Indlela i-WPC Construction Hoarding edlula ngayo iMetal yendabuko kunye nePlywood kwiindawo zokwakha zasezidolophini

Esi sikhokelo sibhalelwe abaphathi beeprojekthi zokwakha ezidolophini, amagosa okhuseleko lwendawo, amaqela okuthenga ucingo lwendawo okwethutyana, kunye nabacebisi bovavanyo lwezakhiwo eziluhlaza abavavanya iindlela zokwakha izakhiwo kwiindawo zokwakha ezixineneyo. Sihamba ngothelekiso olucwangcisiweyo lwe-WPC (wood-plastic composite) yokwakha iindawo ezidityanisiweyo ngokuchasene neendlela ezimbini zemveli (isinyithi esenziwe nge-corrugated kunye ne-plywood), egubungela ixesha lokuphila kwenkonzo ngomjikelo ngamnye wesicelo, ukuthotyelwa kokhuseleko lomlilo ngokwe-EN 13501-1 kunye ne-ASTM E84, ukusebenza kwe-acoustic ngokwe-ISO 10140, ukumelana nokuguquguquka kwemozulu, ixesha lomjikelo wokufaka ngomitha nganye ethe tyaba, indlela yokuphinda isetyenziswe ekupheleni kobomi ngokwemigangatho ye-LEED / BREEAM, kunye neendleko zizonke zobunini kulo lonke ixesha leprojekthi. Imveliso yesalathiso kwiYida Wood-Plastic yi Imveliso yeWPC yokugcina izinto ezingama-206x21, kwaye olu cwangciso lusebenza kuyo nayiphi na iprojekthi yokwakha idolophu apho isigqibo seenkcukacha zokugcinwa kwempahla okwethutyana sivavanywa ngokuthelekisa uhlahlo-lwabiwo mali, ukhuseleko, kunye neenjongo zozinzo lweprojekthi.

Kutheni Ukukhethwa Kwezinto Zokwakha KuyiSigqibo Esibalulekileyo Kwiiprojekthi Zedolophu

Ukugcinwa kwezakhiwo (okubizwa ngokuba yi-site perimeter fencing okanye i-site barrier) lukhuseleko oluyimfuneko kuyo nayiphi na iprojekthi yokwakha idolophu, kwaye ukukhethwa kwezinto kunempembelelo enkulu kakhulu kwixabiso lilonke leprojekthi kunye nokuzinza kunokuba iindleko zokuthenga zokuqala zibonisa. Ukugcinwa kwezakhiwo kusebenzela imisebenzi emininzi ngaphaya komda osisiseko we-perimeter yesiza: kubonelela ngomqobo wokhuseleko ekufikeleleni kwindawo engagunyaziswanga, ukuthintela uthuli kunye nenkunkuma (ngokuthobela imithetho yendalo yasekuhlaleni), ukunciphisa ingxolo kuluntu olujikelezileyo, ithuba lokubonakalisa uphawu olubonakalayo kumphuhlisi kunye nomyili wezakhiwo, kunye nokwanda kwengxelo yozinzo kwiiprojekthi eziqinisekisiweyo ze-LEED / BREEAM. Iindlela ezintathu eziphambili zezinto zokwakha idolophu (isinyithi esenziwe nge-corrugated, i-plywood, kunye ne-WPC) nganye inika ibhalansi eyahlukileyo yale misebenzi, kwaye ukhetho olufanelekileyo luxhomekeke kubude beprojekthi, iimfuno zomthetho wendawo, kunye neenjongo zozinzo lweprojekthi.

Kwiiprojekthi zokwakha zasezidolophini ezinexesha leenyanga ezili-18 ukuya kwezingama-36 kunye nobude bokugcina obuyimitha eziyi-2.4 ukuya kwezingama-3.0, iindleko zezinto zokugcina zihlala zimela ipesenti eyi-0.5 ukuya kwezingama-2.0 yexabiso lilonke leprojekthi, kodwa umahluko weendleko phakathi kwezinto unokuba mkhulu kakhulu xa ixabiso elihlawulweyo kwimijikelo emininzi yeprojekthi liqwalaselwa. Ukugcinwa kwesinyithi esirhabaxa esiqhelekileyo sinobomi benkonzo obuqhelekileyo beminyaka emi-3 ukuya kwemi-5 kwimijikelo yeprojekthi emi-4 ukuya kwezingama-8, ukugcinwa kweplywood kunobomi benkonzo obuqhelekileyo beenyanga ezi-3 ukuya kwezili-12 kwiprojekthi nganye (ngokuyintloko kusetyenziswe kanye kwiiprojekthi zexesha elide), kwaye ukugcinwa kweWPC kunobomi benkonzo obuqhelekileyo beminyaka esi-8 ukuya kwezili-15 kwimijikelo emininzi yeprojekthi. Xa iindleko zokuqala zezinto zihlawulwe kwimijikelo yeprojekthi yokwenyani, ukugcinwa kweWPC kudla ngokuba nexabiso eliphantsi ngomjikelo ngamnye weprojekthi kunye nexabiso eliphantsi lobunini kwiiprojekthi ezinokusetyenziswa okulandelelanayo okuninzi.

Kwiiprojekthi zokwakha ezidolophini ezibeka phambili uzinzo, ukuphinda kusetyenziswe kwakhona kwe-WPC hoarding (ngokugaya nokudibanisa kwakhona) kubonelela ngegalelo elibalulekileyo kwikhredithi yokuchithwa kwenkunkuma yokwakha kwi-LEED v4.1 kunye ne-BREEAM International New Construction. Iphaneli yeWpcIi-s zinokuchazwa ngezinto ezisetyenzisiweyo (ngesiqhelo ziyi-30 ukuya kwi-50 ekhulwini umxholo osetyenzisiweyo emva koshishino), nto leyo enegalelo kwikhredithi yeZixhobo kunye neZixhobo kwi-LEED nakwikhredithi yokufumana izinto ezinoxanduva kwi-BREEAM. Iimveliso zesalathiso kwi Yida Wood-Plastic kuquka uluhlu lwemveliso yephaneli yokuqokelelwa kwe-WPC, Imveliso ye-WPC cladding yakudala (esebenzisa itekhnoloji efanayo yokudibanisa i-co-extrusion kwaye idla ngokuchazwa njengomqobo wesibini wokubonwa okanye njengophawu lokungena kwiprojekthi), kunye I-WPC decking yakudala uluhlu lwemveliso olubonisa ukusebenza kokumelana kwemozulu ixesha elide kunye nozinzo lombala olufezekiswa ziifomyula zeWPC.

Uthelekiso lobomi benkonzo: I-WPC iminyaka eyi-8-15 vs iPlywood iinyanga ezi-3-12 vs iMetal iminyaka emi-3-5

Uthelekiso lobomi benkonzo kuzo zonke izinto ezintathu ezibalulekileyo zokwakha izinto zokugcina izinto zesakhiwo yeyona nto ibalulekileyo ekufuneka iqwalaselwe kwiiprojekthi ezinobude obungaphezulu kweenyanga ezili-12. Ukugcinwa kweplywood (ngesiqhelo i-plywood yomgangatho wokwakha eyi-12 mm ukuya kwi-18 mm) kunobomi obufutshane benkonzo kwiinyanga ezi-3 ukuya kwezili-12 ngeprojekthi nganye kuba i-plywood isengozini enkulu yokufunxwa ngumswakama, ukonakala kwezinto eziphilayo (ukubola, ukungunda, umonakalo weentubi kwiindawo ezishushu), kunye nomonakalo womatshini womphezulu ovela kwiimpembelelo zendawo yokwakha. Ukugcinwa kwesinyithi esenziwe nge-corrugated (ngesiqhelo i-0.5 mm ukuya kwi-0.8 mm ishiti yentsimbi egayiweyo) kunobomi obude benkonzo kwiminyaka emi-3 ukuya kwemi-5 kwimijikelo yeprojekthi emi-4 ukuya kweyisi-8, kodwa iindawo zonxibelelwano zephaneli ukusuka kwisithuba ukuya kwesinye zinokukhula ukubola ngokuhamba kwexesha, kwaye umonakalo obangelwa zizithuthi zendawo yokwakha okanye izinto eziwayo zinokwenza iimbobo ezingapheliyo ezichaphazela ukuqina kwesakhiwo sephaneli kunye nembonakalo ebonakalayo. Ukugcinwa kwe-WPC (ngesiqhelo iphaneli ye-WPC edityanisiweyo enobukhulu obuyi-18 mm ukuya kwi-25 mm) inobomi benkonzo beminyaka esi-8 ukuya kweli-15 kwimijikelo emininzi yeprojekthi ngenxa yokuxhathisa kwezinto ekufunxeni umswakama, ukonakala kwezinto eziphilayo, kunye nomonakalo womatshini womphezulu.

I Ukuqina kweWpc Inzuzo iqhutywa ziimpawu ezine zezinto: (1) izinga lokufunxwa komswakama lingaphantsi kwe-1 pesenti nganye ye-ASTM D570 xa kuthelekiswa ne-8 ukuya kwi-15 pesenti yeplywood yodidi lokwakha, esusa iingxaki zokudumba kunye nokwahlukana ezithintela ubomi benkonzo yeplywood; (2) i-UV-stabilized compound formulation imelana nokufiphala kombala kunye nokutshixwa komphezulu, igcina umgangatho wophawu olubonakalayo kwimijikelo emininzi yeprojekthi; (3) ukuxhathisa kwezinto eziphilayo kuyinxalenye ye-WPC formulation (umxholo weplastiki oqhele ukuba yi-30 ukuya kwi-35 pesenti ye-HDPE okanye i-PVC ubonelela ngomqobo wezinto eziphilayo), isusa iingxaki zokubola kunye neempukane ezichaphazela iplywood kwiimarike zeendawo ezishushu; (4) umaleko wesigqubuthelo se-co-extrusion ufunxa imikrwelo yomphezulu kunye neempembelelo ezincinci ngaphandle kokuveza umongo odibeneyo ongaphantsi, ugcine umgangatho wokubonakala nokuba uphathwa gadalala ngexesha lokufakwa kunye nokususwa kokuhamba.

Kwiiprojekthi zokwakha zasezidolophini ezineenkqubo zokusasazwa ngokulandelelana (ukugcinwa okufanayo okusasazwa kwakhona kwiprojekthi elandelayo emva kokugqitywa kweprojekthi yangoku), iphaneli ye-WPC idla ngokugqiba imijikelo yokusasazwa emi-4 ukuya kwe-8 ngaphambi kokuba ifune ukuhlaziywa okanye ukutshintshwa. Ukuhlaziywa kudla ngokuphela ekuhlaziyeni okubonakalayo (ukusikwa kancinci kunye nokusetyenziswa kwakhona kwe-UV-resistant topcoat) kunye nokutshintshwa kwe-fastener encinci, kunye nesakhiwo sephaneli esihlala sinjalo. Kwi-plywood, ukusasazwa ngokulandelelana akunakwenzeka kuba ukuthembeka kwephaneli kudla ngokusilela emva kokuvezwa kweprojekthi enye. Kwisinyithi esirhabaxa, ukusasazwa ngokulandelelana kunokwenzeka kodwa imbonakalo yephaneli inokonakala kakhulu kwimijikelo emininzi kuba umonakalo wempembelelo kunye nokugqwala kwiindawo zonxibelelwano kudala ukuwohloka kokubonakala okuqhubekayo okusenokungamkeleki kwiiprojekthi zasezidolophini ezibonakala kakhulu.

Ukuthobela uKhuseleko loMlilo: EN 13501-1 kunye nokuthelekiswa kovavanyo lwe-ASTM E84

Ukuthobela ukhuseleko lomlilo yeyona nto yesibini ibalulekileyo ekufuneka iqwalaselwe xa kuqokelelwa izinto zokwakha ezidolophini, kwaye ikhowudi yesakhiwo sendawo idla ngokuchaza ubungakanani bomlilo obuncinci ekufuneka bufikelelwe yinkqubo yokwahlulahlula umlilo ye-European EN 13501-1 (ehlela izinto ukusuka kwi-A1 ezingatshiyo ukuya kwi-F ezingatshiyo) kunye nomgangatho we-ASTM E84 waseMntla Melika (ohlela izinto ukusuka kwi-Class A flame spread 0-25 ukuya kwi-Class D flame spread ngaphezu kwama-200). Ukugcinwa kwesinyithi esenziwe nge-corrugated kufezekisa i-EN 13501-1 Class A1 (engatshiyo) ngokungagqibekanga ngenxa ye-substrate yentsimbi, ebonelela ngomgangatho ophezulu womlilo kodwa ngokutshintshiselana kwexabiso eliphezulu ngeqhekeza ngalinye kunye nesohlwayo sokusebenza kwe-acoustic. Ukugcinwa kwe-WPC kudla ngokufezekiswa i-EN 13501-1 Class B ngokongezwa kwezongezo ezithintela umlilo ngexesha lenkqubo yokudibanisa.

Izithako ezithintela umlilo ezisetyenziswa kwi-WPC formulations zihlala ziyi-aluminium trihydrate (ATH), i-zinc borate, okanye i-magnesium hydroxide, nganye ikwizinga lokulayisha eliyi-10 ukuya kwi-25 ekhulwini ngobunzima. Inqanaba lokulayisha elongezelelweyo limisela umlinganiselo womlilo onokufikelelwa, kwaye lelona lidumileyo. Umthengisi weWpcI-s ingalungisa umthwalo wezongezo ukuze ihlangabezane neemfuno zomgangatho womlilo wemarike yendawo ekuyiwa kuyo (Udidi B ngokwe-EN 13501-1 luluhlu oluqhelekileyo lokugcinwa kwezakhiwo zasezidolophini kwiimarike zaseYurophu, kwaye udidi C ngokwe-ASTM E84 luluhlu oluqhelekileyo kwiimarike zaseMntla Melika). Isongezo se-fire retardant sikwachaphazela iipropati zoomatshini zephaneli ye-WPC kunye nomgangatho wokubonakala, kwaye ingxelo yovavanyo lomlilo yomthengisi kufuneka ibandakanye amaxwebhu omgangatho wokubonakala ukuqinisekisa ukuba umthwalo we-fire retardant awubeki emngciphekweni umphezulu womboniso wophawu.

Kwiiprojekthi zokwakha zasezidolophini apho ukugcinwa kwezindlu kufakwa ecaleni kwezakhiwo ezinabantu abaninzi (iinqaba zokuhlala, izibhedlele, izikolo, iindawo zokuthenga), ikhowudi yesakhiwo sendawo inokufuna umlinganiselo womlilo weKlasi A okanye weKlasi A2, apho ukugcinwa kwezindlu zeWPC ezinezongezo ezithintela umlilo akuyi kwanelisa imfuneko kwaye ukugcinwa kwezindlu zentsimbi ezirhangqiweyo kuya kuba lolona khetho lufanelekileyo. Abathengi bamazwe ngamazwe abachaza ukugcinwa kwezindlu zeWPC kwiiprojekthi zokwakha zasezidolophini ezikufutshane neendawo ezinabantu abanovakalelo kufuneka bacele ingxelo yovavanyo lomlilo yomthengisi kwaye baqinisekise umlinganiselo womlilo kwigunya lolawulo lwezakhiwo lendawo ngaphambi kokuba bagqibezele ukukhetha izixhobo. I-ASTM yaMazwe ngaMazwe ipapasha iindlela zovavanyo ezisemgangathweni zokumisela ireyithingi yomlilo, kunye IKomiti yaseYurophu yoMiselo (CEN) ipapasha indlela yokwahlulahlula ye-EN 13501-1.

Ukusebenza kwe-Acoustic: WPC 25-32 dB vs Metal 12-18 dB nge-ISO 10140 nganye

Ukusebenza kwe-acoustic kuya ngokuya kuba yinto eqwalaselwayo kwiiprojekthi zokwakha ezidolophini ngenxa yemithetho yengxolo yasekuhlaleni ethintela ingxolo yokwakha ngexesha leeyure ezibuthathaka (ngokuqhelekileyo ngokuhlwa, ngeempelaveki, nasekuseni kakhulu kwiindawo zokuhlala nakwiindawo ezisetyenziswa ngeendlela ezahlukeneyo). Ukusebenza kwe-acoustic kwe-hoarding kulinganiswa njengokulahleka kokudluliselwa kwesandi emoyeni ngokwe-ISO 10140, kwaye olu vavanyo luchaphazela ngokuthe ngqo ukunciphisa ingxolo okunikezelwa yi-hoarding kuluntu olujikelezileyo. I-hoarding yokwakha ye-WPC idla ngokufezekisa ilahleko yokudluliselwa kwesandi ye-25 ukuya kwi-32 dB kwiphaneli ye-WPC enobukhulu obuyi-21 mm ngokuchasene ne-12 ukuya kwi-18 dB kwishiti yesinyithi esemgangathweni enobukhulu obulinganayo kunye ne-18 ukuya kwi-25 dB kwi-hoarding yeplywood.

Inzuzo ye-acoustic ye-WPC iqhutywa ikakhulu ziimpawu ezimbini zezinto: (1) uxinano oluphezulu (ngesiqhelo yi-1.2 ukuya kwi-1.4 g/cm³ ye-WPC xa kuthelekiswa ne-0.7 ukuya kwi-0.9 g/cm³ yentsimbi erhabaxa enobukhulu obulinganayo) inika ubunzima obungaphezulu kwindawo nganye ukuvimba ukudluliselwa kwesandi; (2) iimpawu ze-viscoelastic damping ze-WPC compound (indibaniselwano yefayibha yomthi kunye ne-matrix yeplastiki) zifunxa amandla esandi endaweni yokusithumela, zibonelela ngokunciphisa ingxolo eyongezelelweyo ngaphaya kwengqikelelo ye-mass-law. Ukusebenza kwe-acoustic ye-plywood kuphakathi, apho uxinano oluphezulu xa kuthelekiswa nesinyithi lubonelela ngokulahleka okungcono kokudluliselwa kwesandi kodwa uxinano oluphantsi xa kuthelekiswa ne-WPC lubonelela ngokufunxwa kwesandi okuncinci.

Kwiprojekthi zokwakha zasezidolophini ezikufutshane neendawo ezihlala abantu abanengxaki yengxolo (ezokuhlala, ezempilo, ezemfundo), ukusebenza okuphezulu kwe-acoustic kwe-WPC hoarding kubonelela ngokunciphisa i-10 ukuya kwi-15 dB kwinqanaba lengxolo yomsebenzi wokwakha efikelela kwizakhiwo ezingqongileyo, nto leyo enokuba ngumahluko phakathi kokusebenza okuthotyelwayo kunye nokwaphulwa komthetho wengxolo ngexesha leeyure ezinobuzaza. Abathengi bamazwe ngamazwe abachaza i-WPC hoarding kwiindawo zasezidolophini ezinobuzaza kufuneka bacele ingxelo yovavanyo lwe-acoustic ye-ISO 10140 yomthengisi ukuqinisekisa ixabiso lokulahleka kokudluliselwa kwesandi kubukhulu bepaneli ethile efunyenweyo, kwaye umcebisi we-acoustic weprojekthi kufuneka abandakanyeke ukuqinisekisa ukuba ukunciphisa ingxolo okuqikelelweyo kwindawo kuyahlangabezana neemfuno zomthetho wengxolo wendawo.

Imibuzo Ebuzwa Rhoqo evela kuMaqela okuThenga i-Urban Construction Hoarding

Ingakanani ixesha eliqhelekileyo lenkonzo yokugcinwa kwe-WPC xa kuthelekiswa nokugcinwa kwe-plywood kunye ne-metal?
Ubomi obuqhelekileyo benkonzo yokugcinwa kwe-WPC (umthi-plastiki odityanisiweyo) kwizakhiwo zasezidolophini buyiminyaka esi-8 ukuya kweli-15 kwimijikelo emininzi yeprojekthi kunye nokugcinwa okufanelekileyo, kudlula kakhulu ukugcinwa kwe-plywood iinyanga ezi-3 ukuya kwezili-12 kwiprojekthi nganye kunye nokugcinwa kwe-corrugated metal iminyaka emi-3 ukuya kwemi-5 kwimijikelo emininzi yeprojekthi. Inzuzo yokuqina kwe-WPC ivela kukumelana kwezinto ezisetyenziswayo ekufunxeni umswakama (ngaphantsi kwe-1% yokufunxwa kwamanzi kwi-ASTM D570 nganye xa kuthelekiswa ne-8 ukuya kwi-15% ye-plywood yodidi lokwakha), i-UV-stabilized compound formulation yayo echasene nokufiphala kombala kunye nokutshixwa komphezulu, ukumelana kwayo nokuwohloka kwezinto eziphilayo (akukho kubola, akukho kubola, akukho monakalo weentubi), kunye nokumelana kwayo nempembelelo yoomatshini echasene nokuqhekeka kunye nokubhobozwa okuqhelekileyo kwiindawo zokwakha. Ubomi benkonzo obulindelekileyo bephaneli yokuqokelelwa kwe-WPC buqhutywa ziindlela ezintathu eziphambili zokuwohloka: (1) ukufiphala kombala okubangelwa yi-UV (okujongwa ngokongezwa kweziqinisi ze-UV kwifomyula edibeneyo), (2) umonakalo wempembelelo yoomatshini (okujongwa ngumaleko wesigqubuthelo sephaneli esidibanisa imikrwelo kunye neempembelelo), kunye (3) ukudinwa kwe-fastener kuqhagamshelo lwephaneli ukusuka kwisithuba ukuya kwesinye (okujongwa yinkcazo ye-fastener yentsimbi engagqwaliyo). Kwiiprojekthi zokwakha zasezidolophini ezinexesha leenyanga ezili-18 ukuya kwezingama-36, i-WPC yokuqokelelwa kwe-WPC idla ngokusinda kwiprojekthi ngokulungiswa okuncinci komphezulu kwaye inokusetyenziswa kwakhona kwiiprojekthi ezilandelayo, okunciphisa kakhulu iindleko ezihlawulweyo kwiprojekthi nganye.

Ukuqokelelwa kwe-WPC kuthelekiswa njani nokuqokelelwa kwe-plywood kunye ne-metal ngokwemithetho yokhuseleko lomlilo?
Ukugcinwa kwe-WPC ngokuqhelekileyo kufikelela kwinqanaba lomlilo leKlasi B ngokwemigangatho ye-EN 13501-1 yaseYurophu (elingana neKlasi B ye-ASTM E84 eMntla Melika), kunye nokongezwa kwezongezo ezithintela umlilo ngexesha lenkqubo yokudibanisa. Ukugcinwa kwesinyithi esine-corrugated kufikelela kwinqanaba le-A1 (elingenakutsha) ngokwe-EN 13501-1 ngokwesiqhelo, kubonelela ngomgangatho ophezulu womlilo kodwa kunye nokutshintshana kweendleko eziphezulu ngeqhekeza ngalinye, ubunzima bokufakelwa obunzima, kunye nokusebenza okuphantsi kwe-acoustic. Ukugcinwa kwe-plywood ngokuqhelekileyo kufikelela kwinqanaba le-Class D ukuya kwiKlasi C ngokuxhomekeke kunyango, kunye ne-plywood enganyangwanga elinganiswe njengeKlasi D (umgangatho ophantsi owamkelekileyo kwiindawo ezininzi zasezidolophini) kunye ne-plywood ethintelwe ngumlilo elinganiswe njengeKlasi C. Kwiiprojekthi zokwakha zasezidolophini apho ukugcinwa kwe-plywood kufakwe kufutshane nezakhiwo ezinabantu, imfuneko yomgangatho womlilo ngokuqhelekileyo yiKlasi B okanye ngaphezulu ngokwekhowudi yesakhiwo sendawo, kwaye ukugcinwa kwe-WPC ngesongezo esithintela umlilo kuhlangabezana nale mfuneko ngexabiso elikhuphisanayo ngeqhekeza ngalinye. Abathengi bamazwe ngamazwe kufuneka bacele ingxelo yovavanyo lomlilo yomthengisi ngokwe-EN 13501-1 okanye i-ASTM E84 ukuqinisekisa ukuba umlinganiselo womlilo ufezekiswa rhoqo kwiibhetshi zemveliso, kwaye uhlobo lwesongezo esithintela umlilo (ngesiqhelo i-aluminium trihydrate okanye i-zinc borate) kufuneka luchazwe kwiphepha ledatha yezinto eziphathekayo.

Ingakanani intsebenzo ye-acoustic enikezelwa yi-WPC hoarding xa ithelekiswa nesinyithi kunye neplywood?
Ukugcinwa kwe-WPC kwisakhiwo kubonelela ngokusebenza okuphezulu kakhulu kwe-acoustic xa kuthelekiswa nokugcinwa kwe-corrugated metal, kunye nokulahleka kokudluliselwa kwesandi emoyeni ngokwe-ISO 10140 ngokuqhelekileyo ukusuka kwi-25 ukuya kwi-32 dB kwiphaneli ye-WPC enobukhulu obuyi-21 mm xa kuthelekiswa ne-12 ukuya kwi-18 dB kwishidi lesinyithi elisemgangathweni elinobukhulu obulinganayo. Inzuzo ye-acoustic ye-WPC ibangelwa ikakhulu bubuninzi bezinto ezibonakalayo (ngesiqhelo yi-1.2 ukuya kwi-1.4 g/cm³ ye-WPC xa kuthelekiswa ne-0.7 ukuya kwi-0.9 g/cm³ yentsimbi ebotshelelweyo kubukhulu obulinganayo) kunye neempawu ze-viscoelastic damping zezixhobo ezifunxa amandla esandi endaweni yokuwathumela. Kwiiprojekthi zokwakha zasezidolophini ezikufutshane nezakhiwo zokuhlala okanye zorhwebo ezinabantu, ukusebenza kwe-acoustic kwe-hoarding yinto ebalulekileyo ekufuneka iqwalaselwe kuba umthetho wengxolo yendawo uhlala unciphisa ingxolo yomsebenzi wokwakha ngexesha leeyure ezinobuzaza, kwaye ukugcinwa kwengxolo ephezulu kunciphisa umthwalo wengxolo kuluntu olujikelezileyo. Ukugcinwa kwe-plywood kubonelela ngokusebenza kwe-acoustic phakathi kwe-WPC kunye nesinyithi (ngesiqhelo yi-18 ukuya kwi-25 dB) kodwa ngexesha elifutshane kakhulu. Abathengi bamazwe ngamazwe abachaza ukugcinwa kweWPC kwiindawo zasezidolophini ezinengxaki yengxolo kufuneka bacele ingxelo yovavanyo lwe-acoustic ye-ISO 10140 yomthengisi ukuqinisekisa ixabiso lokulahleka kokudluliselwa kwesandi kubukhulu bephaneli ethile efunyenweyo.

Iiphaneli ze-WPC zokuhombisa kufuneka zifakwe njani kwindawo eqhelekileyo yokwakha edolophini?
Ufakelo lwephaneli yokubeka izinto zokwakha iWPC lulandela inkqubo eqhelekileyo enamanyathelo amathathu ekhawulezayo kakhulu kune-corrugated metal equivalent: (1) uphando lwendawo kunye noyilo lweposi, kunye neendawo zeposi eziphawulwe kwizithuba ze-2.0 ukuya kwi-2.5 yeemitha ngokuxhomekeke kwimfuneko yomthwalo womoya wendawo, (2) ukufakwa kweposi kusetyenziswa iintsika zentsimbi ezifakwe kwikhonkrithi okanye iintsika zentsimbi eziqhutywayo ezinekhola yekhonkrithi, kunye nobungakanani beposi obukhethiweyo ngokomgangatho womthwalo womoya wendawo (ngesiqhelo i-50 mm × 50 mm ukuya kwi-80 mm × 80 mm isikwere esingenanto esisikwere sokuphakama kweposi ye-2.5 yeemitha), kunye (3) ukufakwa kwephaneli ngokutyibiliza imiphetho yephaneli yeWPC yolwimi kunye ne-groove kwiitshaneli zeposi kwaye uyiqinise ngeekliphu zentsimbi engagqwaliyo okanye izikrufu zokuzicofa. Ixesha lomjikelo wokufakelwa kwecandelo eliqhelekileyo lokuqokelelwa kwempahla ezidolophini (iimitha ezingama-30 ezithe tyaba) limalunga neeyure ezi-4 ukuya kwezi-6 kwiqela labantu abane abasebenzisa iiphaneli ze-WPC, xa kuthelekiswa neeyure ezi-6 ukuya kwezili-10 zokufakelwa kwempahla yesinyithi efanayo ngenxa yobunzima bephaneli elula (ngesiqhelo yi-8 ukuya kwi-12 kg ngephaneli ye-WPC xa kuthelekiswa ne-18 ukuya kwi-25 kg ngephepha lesinyithi) kunye nenkqubo yoqhagamshelo lolwimi kunye nomngxuma olusetyenziswa ngendlela efanayo. Umjikelo wokuqhaqha wokususwa kweprojekthi ukhawuleza ngendlela efanayo, kunye neephaneli ze-WPC zihlala zisetyenziswa kwakhona izihlandlo ezi-4 ukuya kwezi-8 kwiiprojekthi zasezidolophini ezilandelelanayo ngokuxhomekeke kwimeko yephaneli. Abathengi bamazwe ngamazwe abachaza ukuqokelelwa kwempahla ze-WPC kufuneka baqinisekise inkqubo yeposi ecetyiswayo ngumthengisi (ehambelana nobunini okanye umntu wesithathu), iinkcukacha zoqhagamshelo lwephaneli ukusuka kwiposi ukuya kwiposi, kunye nomlinganiselo ophezulu womthwalo womoya ngokomgangatho wendawo.

Ithini indlela yokulahla iiphaneli zokugcina i-WPC ekupheleni kobomi?
Iiphaneli zokuqokelela izinto zokwakha zeWPC ezifikelele esiphelweni sobomi bazo zinokuphinda zisetyenziswe ngokusila ngoomatshini kunye nokudibanisa kwakhona zibe ziimveliso ezintsha zeWPC, kunye neWPC esetyenzisiweyo enomlinganiselo ofanayo neWPC engasebenziyo kwizicelo ezininzi ezingezizo ezolwakhiwo kubandakanya ukugoba okwesibini, ii-slats zocingo, kunye nomgca womhlaba. Inkqubo yokuphinda isetyenzwe idla ngokubandakanya ukuqokelelwa kweephaneli zokuphela kobomi, ukugoba ngoomatshini zibe ziitships ezi-5 ukuya kwi-10 mm, ukususwa kwesinyithi (kwizibophelelo ezifakwe ngaphakathi kunye nayo nayiphi na insimbi eqinisiweyo), ukuhlamba ukuze kususwe izinto ezingcolisayo kumphezulu, kunye nokudibanisa kwakhona ngezinto ezongezelelweyo zeWPC esetyenzisiweyo kunye nezongezo ukuvelisa iWPC esetyenzisiweyo enomlinganiselo osetyenzisiweyo. Ukugoba ngentsimbi eqinisiweyo kunokuphinda kusetyenzwe ngekhonkco lokuphinda kusetyenzwe ngentsimbi, kodwa uqhagamshelo lwephaneli ukusuka kwisithuba ludla ngokuphumela kwinkunkuma yezinto ezixutyiweyo ezifuna ukwahlulwa ngaphambi kokuba kusetyenzwe kwakhona. Ukugoba ngeplywood kudla ngokusetyenziselwa ukulahla inkunkuma okanye ukubuyiselwa kwamandla e-biomass kuba iikhemikhali zonyango lweenkuni (ingakumbi unyango oluthintela umlilo) zithintela ukhetho lokuphinda kusetyenzwe kwakhona. Kwiiprojekthi zokwakha zasezidolophini ezibeka phambili isiqinisekiso se-LEED, isiqinisekiso se-BREEAM, okanye ukuthotyelwa komgangatho wezakhiwo eziluhlaza zasekuhlaleni, ukuphindeka kwakhona kwe-WPC hoarding kuncedisa kwikhredithi yokuchithwa kwenkunkuma yokwakha kwaye kuxhasa injongo yozinzo iyonke yeprojekthi. Abathengi bamazwe ngamazwe abachaza i-WPC hoarding kufuneka bacele amaxwebhu enkqubo yokuphinda isetyenziswe yomthengisi ekupheleni kobomi kwaye baqinisekise ipesenti yomxholo ophinda usetyenziswe ekhoyo kumjikelo olandelayo weprojekthi.

Kwabaphathi beeprojekthi zokwakha ezidolophini, amagosa okhuseleko lwendawo, kunye namaqela okuthenga ucingo lwendawo okwethutyana avavanya ukugcinwa kweWPC, iqela lokuthumela ngaphandle leYida Wood-Plastic libonelela ngesikhokelo seenkcukacha zeWPC compound (ukukhethwa kwezongezo zovavanyo lomlilo, ukulayisha i-UV stabilizer, ipesenti yomxholo ophinda usetyenziswe), ukwenziwa ngokwezifiso kobukhulu bemida ethile yeprojekthi, ulungelelwaniso lwengxelo yovavanyo lomlilo lwe-EN 13501-1 kunye ne-ASTM E84, ulungelelwaniso lwengxelo yovavanyo lwe-acoustic lwe-ISO 10140, kunye nocwangciso lokuhanjiswa kwindawo yemijikelo yeprojekthi elandelelanayo. Iphepha loqhagamshelwano leYida Wood-Plastic kunye nendawo yeprojekthi yakho, imfuneko yakho yokulinganisa umbane, iimfuno zakho zokulinganisa umlilo kunye nomthetho wengxolo, kunye nobude bexesha leprojekthi yakho. Ubungakanani obuncinci be-odolo yekhathalogu eqhelekileyo yiziqwenga ezingama-5,000 ngokomgaqo-nkqubo wemveliso yomthengisi; ukwenziwa ngokwezifiso kwe-OEM (ubukhulu obuqhelekileyo, ukulayisha okuthintelwa ngumlilo okwenziwe ngokwezifiso, iphakheji ye-UV-stabilizer eyenziwe ngokwezifiso, umbala owenziwe ngokwezifiso) ifumaneka kwiiziqwenga ezingama-50,000 ubuncinane be-odolo.
