Izixhobo zokulungisa zePVC luhlobo lwezongezo zekhemikhali ezisetyenziswa kwimveliso yeplastiki, kwaye zininzi iindidi zePVC zokuncedisa ekusetyenzweni. Yeyiphi imisebenzi yezixhobo ezahlukeneyo zokusetyenzwa kwePVC?

I-Heat stabilizer: Ukulungiswa kweplastiki kunye nokubunjwa kuya kuqhutyelwa unyango lokufudumeza, kwaye ngexesha lokufudumeza, iplastiki ayinakwenzeka ukuba isebenze ngokungazinzi. Ukongeza i-heat stabilizers kukuzinzisa ukusebenza kwezinto ze-PVC ngexesha lokufudumala.

Ukuphuculwa kwezixhobo zokulungisa: Njengoko igama libonisa, into ebizwa ngokuba yi-processing aid ephuculweyo yenzelwe ukuphucula ezinye iipropathi zePVC ngexesha lokucubungula, kubandakanywa nokuphucula ukuhamba kakubi kwePVC, ekulungele ukunamathela kwizixhobo kunye nokupheka. Ke ngoko, inani elithile lezixhobo zokuncedisa kufuneka zongezwe kwimveliso yeeprofayili zeplastiki ukoyisa iziphene zeeprofayili zeplastiki ngokwazo.

IiFillers: Izigcwalisi zizongezo eziqinileyo ezahlukileyo ngokubunjwa kunye nesakhiwo kwiiplastiki, ezikwabizwa ngokuba zizizalisi. Ineempembelelo ezibalulekileyo kunye nexabiso lezoqoqosho ekuphuculeni iimpawu ezithile zomzimba kunye noomatshini beeplastiki kunye nokunciphisa iindleko zeplastiki. Ukongeza izihluzi kwifomula yemveliso yeeprofayili zeplastiki kunokunciphisa isantya sokutshintsha ubungakanani emva kokufudumeza, ukuphucula amandla empembelelo, ukwandisa ubulukhuni, kunye nokunciphisa iindleko zemveliso.

I-Lubricant: Umsebenzi ophambili we-lubricant kukunciphisa ukungqubuzana phakathi kwepolymer kunye nezixhobo zokucubungula, kunye naphakathi kweemolekyuli zangaphakathi ze-polymer, ukuthintela ukuthotywa kwe-resin okubangelwa ukushisa okugqithiseleyo, kunye nokuphucula ukusebenza kakuhle kwezinzisi zokushisa.
