Yintoni kanye kanye le nto isetyenziswa kwezi zinto zimbini?
Idekhi ye-WPC (umthi-plastiki odityanisiweyo) yenziwe ngefayibha yomthi okanye umgubo womthi idityaniswe neepolymers zeplastiki (ngesiqhelo i-HDPE, i-PVC, okanye i-PP) kunye nezongezo zozinzo lwe-UV, umbala, kunye nokudibanisa. Umxholo womthi udla ngokuba phakathi kwama-50% ukuya kuma-70% ngobunzima, kwaye okunye kuphakathi kwepolymer kunye nezongezo. Idekhi ye-HDPE yenziwe ngeplastiki ye-polyethylene ephezulu eyi-100%, edla ngokungabi namxholo womthi konke konke - ipolymer kuphela, umbala wepigment, kunye neziqinisi ze-UV.
Umahluko ophambili wokusebenza kukuba i-HDPE yenziwe ngokupheleleyo kwaye ayingeni manzi ngokupheleleyo ngenxa yokwakheka kwezinto, ngelixa i-WPC ixhomekeke kumaleko we-polymer cap (kwi-WPC edibeneyo) okanye unyango lomphezulu (kwi-WPC yesizukulwana sokuqala) ukugcina amanzi engangeni embindini womthi-plastiki. Ibali ledekhi yedama lePhuket elingasentla liyimpazamo ye-WPC yesizukulwana sokuqala; i-WPC edibeneyo iziphatha ngendlela eyahlukileyo kakhulu ngenxa yomaleko we-cap.
Ngaphakathi kwi-WPC, umahluko phakathi kwesizukulwana sokuqala ne-co-extrusion ubaluleke kakhulu kunomahluko phakathi kwe-WPC ne-HDPE kwizicelo zokufuma okuphezulu. I-WPC yesizukulwana sokuqala inomxube ofanayo womthi-plastiki kuyo yonke ibhodi, ngoko ke naluphi na ucezu olusikiweyo okanye umkrwelo womphezulu uveza ifayibha yomthi emanzini. I-Co-extrusion WPC ibopha umaleko wesigqubuthelo sepolymer (ngesiqhelo ubukhulu obuyi-0.5-1.5mm) kumbindi womthi-plastiki ngexesha lenkqubo yokukhupha, ovala ifayibha yomthi ekuchaphazekeni kwamanzi kumphezulu ophezulu nakumacala omabini. Umaleko wesigqubuthelo ukwabonelela nge-wood-grain embossing, umbala ogqamileyo, kunye nozinzo lwe-UV, okushiya umbindi ubonelela ngamandla olwakhiwo. Yingakho umgca wethu wemveliso ye-YD140H23 usebenzisa i-co-extrusion kuphela - senze ubizo lokuyeka isizukulwana sokuqala. Imveliso yeWpci-ion ngo-2022 emva kokubona ukungaphumeleli okuninzi kwentsimi njengePhuket deck.
Kwi-HDPE decking, inkqubo yokuvelisa isondele kwi-extrusion yeplastiki eqhelekileyo. Ii-pellets ze-HDPE ziyanyibilikiswa kwaye zinyanzeliswe nge-die eyenza iprofayili yebhodi, emva koko zipholiswe kwaye zinqunyulwe zibe nobude. Umbala we-pigment uxutywa kwii-pellets ze-HDPE ngaphambi kokuba zikhutshwe, ngoko ke umbala uhamba yonke ibhodi. I-HDPE ayiwamkeli ama-wood-grain embossing acocekileyo njenge-WPC, kodwa imigca ye-HDPE decking yanamhlanje inokuvelisa umphezulu onombala ofana ne-wood grain ebonakalayo, nokuba ayinayo ubunzulu bemibala emininzi be-WPC.

Idekhi ye-WPC edityanisiweyo idla ngokuthatha iminyaka eli-15-25 kwidekhi yedama kunye nokufakwa kwamanzi ngokufakelwa nokugcinwa okufanelekileyo. Idekhi ye-HDPE idla ngokuthatha iminyaka engama-20-30. Zombini ezi zinto zihlala ixesha elide kunemithi yendalo (iminyaka emi-5-10) kwiindawo ezifanayo. Umahluko wobomi phakathi kwezi zimbini ungaphantsi komahluko phakathi kwemithi nemithi.
6. Ngaba idekhi yeWPC iyatshisa xa ilanga litsho ngqo?
Zombini iidekhi zeWPC kunye neHDPE ziyatshisa elangeni ngqo, kwaye amaqondo obushushu obuphezulu afikelela kwi-50-65°C kwiimeko zasehlotyeni eziphezulu. Imibala ekhanyayo ihlala ipholile kunemibala emnyama. Kwizicelo zeedekhi zedama lokudada ezingenazicathulo, sicebisa ukuba kubekho imibala ekhanyayo yeWPC okanye iHDPE kunye nezakhiwo zomthunzi ukuze kugcinwe amaqondo obushushu obuphezulu elawuleka. Ukuqhuba kobushushu kuyafana phakathi kwezinto ezimbini.
