I-PVC resin esetshenziselwa ukukhiqiza i-WPC, Izinto ezingavuthiwe zokukhiqizwa kwe-WPC.,
I-WPC iwuhlobo olusha lwezinto ezivikela imvelo, ezixutshwa ngokhuni nepulasitiki, nokuthungwa kokhuni nokuqina kwepulasitiki.Inqubo yokukhiqiza ye-WPC ikakhulukazi ihlanganisa ukulungiswa kwempahla eluhlaza, ukuxuba, ukukhipha, ukupholisa, ukusika nokupakisha.
Ukulungiswa kwezinto ezingavuthiwe kuyisinyathelo sokuqala ekukhiqizeni i-WPC.Izinto zokusetshenziswa ze-WPC ikakhulukazi zifaka ufulawa wezinkuni, amapulasitiki, izithasiselo nokunye.Phakathi kwazo, ufulawa wezinkuni wenziwa ngokhuni ngemuva kokuchotshozwa, ukuhlolwa nezinye izinqubo, futhi ipulasitiki yenziwe nge-polyethylene, i-polypropylene nezinye izinto zokusetshenziswa kwepulasitiki.Izithasiselo zifaka izinto ezigcina imvelo, ama-antioxidants, ama-pigments, njll., asetshenziselwa ukuthuthukisa ukusebenza nobuhle be-WPC.
Ukuxuba kuyinqubo yokuxuba ufulawa wezinkuni, ipulasitiki kanye nezithasiselo ngesilinganiso esithile.Inhloso yokuxuba ukwenza izinto ezihlukahlukene zokusetshenziswa zihlanganiswe ngokugcwele ukuze zenze ingxube efanayo, ilungele inqubo ye-extrusion elandelayo.
Khona-ke, i-extrusion iyinqubo yokukhama izinto zokusetshenziswa ezixubile nge-extruder.I-extruder ishisa impahla eluhlaza exubene ezingeni elithile lokushisa ukuze ithambile, bese iyikhipha ngesikhunta.I-extruded wood-plastic board inomumo nobukhulu obuthile, kodwa futhi idinga ukupholisa nokusikwa.
Bese, ukupholisa kuyinqubo yokubeka i-WPC ekhishwe endaweni yokupholisa ukuze iphole ngokwemvelo.Inhloso yokupholisa ukupholisa ngokushesha i-WPC, ukwenza ukwakheka kwayo nosayizi kuzinze, futhi kugwenywe izinkinga ezinjengokuguqulwa nokuqhekeka.
Ukusika nokupakisha kuyinqubo yokusika nokupakisha i-WPC epholile.Ukusika ukusika ibhodi lezinkuni-plastiki ngokuhambisana nobukhulu obuthile, ukuze lihlangabezane nezidingo zamakhasimende.Ukupakisha ukusika ibhodi lepulasitiki lezinkuni ukuze lifakwe, ukuze kube lula ukuhamba nokuthengisa.
Inqubo yokukhiqiza ye-WPC ihlanganisa ukulungiswa kwempahla eluhlaza, ukuxutshwa, ukukhishwa, ukupholisa, ukusika nokupakisha.Lezi zixhumanisi ziyasebenzisana ukuze kuphothulwe inqubo yokukhiqiza ye-WPC, ihlinzeka abantu ngezinto ezintsha ezinobungani nemvelo, ezinhle futhi ezihlala isikhathi eside.
I-Polyvinyl Chloride, ebizwa ngokuthi i-PVC, ingenye yezinhlobo zepulasitiki ezithuthukisiwe, okukhiphayo okwamanje kungokwesibili ngemuva kwe-polyethylene.I-Polyvinyl chloride isetshenziswe kabanzi embonini, ezolimo kanye nempilo yansuku zonke.I-Polyvinyl chloride iyinhlanganisela ye-polymer eyenziwe nge-vinyl chloride.I-thermoplastic.Impushana emhlophe noma ekhanyayo ephuzi.Incibilika kuma-ketone, esters, tetrahydrofuran kanye nama-hydrocarbon ane-chlorine.Ukumelana kwamakhemikhali okuhle kakhulu.Ukungaqini kahle kokushisa nokumelana nokukhanya, ukukhanya kwelanga okungaphezu kuka-100 ℃ noma isikhathi eside kwaqala ukubola i-hydrogen chloride, ukukhiqizwa kwepulasitiki kudinga ukwengeza isizinzi.Ukufakwa kukagesi kuhle, ngeke kushise.
Ibanga S-700isetshenziswa kakhulu ukukhiqiza amaphepha abonisa ngale, futhi ingagoqeka ibe amashidi aqinile futhi angaqinile ukuze ahlanganiswe, impahla yaphansi, ifilimu eqinile yolwelwesi (yephepha lokugoqa uswidi noma ifilimu yokupakisha ugwayi), njll. ifilimu elincane eliqinile, ishidi, noma ibha emise ngendlela engavamile yephakheji.Noma ingajovwa ukwenza amalunga, ama-valve, izingxenye zikagesi, izesekeli ezizenzakalelayo kanye nemikhumbi.
