I-PVC isifinyezo se-polyvinyl chloride.I-resin yinto evame ukusetshenziswa ekukhiqizeni amapulasitiki namarabha.I-PVC resin iyimpushana emhlophe evame ukusetshenziselwa ukukhiqiza i-thermoplastics.Yimpahla yokwenziwa esetshenziswa kabanzi emhlabeni namuhla.I-Polyvinyl chloride resin inezici ezivelele njengokuchichima kwezinto zokusetshenziswa, ubuchwepheshe bokukhiqiza obuvuthiwe, intengo ephansi, kanye nenhlobonhlobo yokusetshenziswa.Kulula ukucubungula futhi ingacutshungulwa ngokubumba, i-laminating, ukubunjwa komjovo, i-extrusion, i-calendering, i-blow molding nezinye izindlela.Ngezakhiwo ezinhle zomzimba namakhemikhali, isetshenziswa kabanzi embonini, kwezokwakha, ezolimo, empilweni yansuku zonke, ekupakishayo, ugesi, izinsiza zomphakathi, nakweminye imikhakha.Ama-resin e-PVC ngokuvamile anokumelana namakhemikhali aphezulu.Inamandla kakhulu futhi imelana namanzi nokuhuzuka.I-Polyvinyl chloride resin (PVC) ingacutshungulwa ibe yimikhiqizo ehlukahlukene yepulasitiki.I-PVC iyipulasitiki engasindi, engabizi, futhi enobungani bemvelo.I-Pvc Resin ingasetshenziswa kumapayipi, amafreyimu amafasitela, amapayipi, izikhumba, izintambo zocingo, izicathulo kanye neminye imikhiqizo ethambile evamile, amaphrofayili, okokufakwayo, amaphaneli, umjovo, ukubumba, izimbadada, ishubhu eliqinile nezinto zokuhlobisa, amabhodlela, amashidi, ikhalenda, umjovo oqinile kanye nokubunjwa, njll nezinye izingxenye.
Izici
I-PVC ingenye yezinhlaka ze-thermoplastic ezisetshenziswa kakhulu.Ingasetshenziselwa ukwenza imikhiqizo enobulukhuni obuphezulu namandla, njengamapayipi nokufakwa, iminyango enephrofayili, amafasitela namashidi okupakisha.Ingakwazi futhi ukwenza imikhiqizo ethambile, efana namafilimu, amashidi, izintambo zikagesi nezintambo, amabhodi aphansi kanye nesikhumba sokwenziwa, ngokwengeza ama-plasticizers.

Isicelo
I-PVC resin iyi-resin ye-molecular weight suspension ephakathi nendawo ye-PVC elungele imikhiqizo eqinile ye-extrusion.Kunconywa ngokukhethekile amapayipi aqinile namapayipi,amaphrofayili aqinile, amashidi aqinile, ifilimu yeshubhu engafakwanga epulasitiki njll. Inhlanganisela yayo yesisindo samangqamuzana aphakathi nendawo enobuningi obubonakalayo obuphezulu iyenza ifaneleke ukucutshungulwa kalula ngezinga eliphezulu lokuphumayo, isagcina izakhiwo eziphezulu zemishini.Impahla yayo yokulahlekelwa ukushisa elinganiselwe ayivumeli i-static ukuthuthukisa futhi inciphisa isikhathi sokugeleza.Ngesikhathi esifanayo i-resin iqukethe ama-volatiles amancane.Uhlu oluncane lwe-porosity lwenza kube lula ukugcina iphoyinti lokuhlanganisa elilinganayo ezingeni elihlala njalo lokuthambisa.Ukuqina okulinganayo kwezinhlamvu zale resin kuholela ekuphathweni kwenqwaba kalula, isidingo esincane se-lubricant kanye nokuguquguquka okufanayo ku-extruder.
