Cov khoom siv dav siv rau lub teeb yas muaj xws li polyvinyl chloride (PVC) alloys, polycarbonate, polymethyl methacrylate (PMMA), PVC, polystyrene, thiab polyethylene. Cov ntaub ntawv no tau siv dav hauv cov khoom siv hluav taws xob tsim hluav taws xob vim lawv lub teeb xa hluav taws xob zoo heev, dej tsis kam, ua haujlwm ntev, yooj yim ntawm molding, yooj yim colouring, aging kuj, lub teeb yuag, thiab tus nqi qis.
Lub teeb yas muaj qhov zoo hauv qab no:
Kev ruaj ntseg tshuaj zoo: Cov roj teeb yas tiv taus cov kua qaub, alkalis, thiab tshuaj lom neeg corrosion, ua rau lawv haum rau ntau qhov chaw.
Cov khoom siv hluav taws xob zoo heev: Cov tshuaj chlorine hauv PVC ua rau nws cov khoom siv hluav taws xob zoo heev, nrog rau qhov ntsuas pa siab thiab FV0 qhov ntsuas kub, txhim kho kev nyab xeeb.
Lub neej ua haujlwm ntev: PVC tsis yoog rau kev laus thaum siv sab nraum zoov, thiab nws lub neej kev pabcuam tuaj yeem ncav cuag 20 xyoo.
Zoo qis-kub tsis kam: Hloov PVC alloys tuaj yeem siv ib txwm qis dua 30 degree, yoog rau ntau yam qis- qhov kub thiab txias.
Kev cuam tshuam siab: Los ntawm kev ntxiv qis- cov khoom siv hluav taws xob tiv taus kub thiab cuam tshuam- cov neeg ua haujlwm tiv thaiv, qhov cuam tshuam tsis zoo ntawm cov khoom siv PVC hloov kho tau zoo dua qub, txhim kho cov kav ntev ntawm cov teeb pom kev zoo.
Zoo waterproofing: PVC muaj zog polarity thiab zoo compatibility nrog ntau yam nplaum, kom ntseeg tau lub watertightness thiab airtightness ntawm lub teeb pom kev zoo fixtures, ua rau lawv haum rau huab cua puag.
