PVC K inani 57,
I-PVC resin esetshenziselwa ukwenza ibhodi legwebu,
I-resin ye-PVC enenani le-K lama-55-68 ingasetshenziswa ukwenza igwebu eliqinile, okungukuthi, imikhiqizo eqinile ye-PVC ye-foam ephansi, ehlukile kunani lika-K elinikezwe ulwazi oludlule kanye nezincwadi.Ama-resin e-PVC anamanani e-K angu-69-77 aboniswe ukuthi afaneleka ukwakhiwa kwamagwebu athambile.Kunezindlela eziningi zokukhiqiza i-PVC resin, indlela yokumiswa, indlela ye-emulsion kanye ne-polymerization ngobuningi be-PVC resin ziyatholakala izinto zokusetshenziswa zemikhiqizo enegwebu, ngokuvamile ukumiswa kanye ne-polymerization ngobuningi be-PVC resin kufanelekile.Ama-copolymers e-PVC nama-polymer axhunyelelwe (ama-polymers ayi-granular) nawo anokucutshungulwa okuhle futhi awavamile ukusetshenziswa ngenxa yezici zentengo.
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.
