Olyvinyl chloride, feem ntau hu ua PVC, yog ntau yam khoom siv thermoplastic uas muaj ntau yam kev siv thoob plaws ntau yam kev lag luam. PVC yog tsim los ntawm 57 feem pua chlorine thiab 43 feem pua carbon, ua rau nws yog ib qho ntawm cov khoom siv nrov tshaj plaws hauv kev lag luam thiab kev lag luam.
PVC cov khoom siv dav siv vim nws cov khoom tshwj xeeb xws li kev ua haujlwm ntev, yooj yim, tsis tshua muaj txij nkawm, thiab muaj zog. Cov yam ntxwv ntawm PVC ua rau nws xaiv zoo rau ntau yam kev siv xws li kev tsim kho, kev kho mob, tsheb, hluav taws xob, thiab ntim khoom. Hauv tsab xov xwm no, peb yuav tham txog qee qhov kev siv ntawm cov khoom siv PVC.
PVC yog dav siv nyob rau hauv kev tsim kho kev lag luam vim nws lub zog, toughness, thiab tsis kam mus rau tshuaj. Piv txwv li, cov kav dej PVC yog siv rau hauv ntau daim ntawv thov xws li dej, dej phwj tuaj, cov kav dej, cov kav dej, thiab cov kab hluav taws xob hauv av. PVC kuj tseem siv rau hauv kev tsim cov qhov rais thiab qhov rooj, vov tsev, guttering, thiab soffits.
Vim nws cov dej tsis zoo thiab hluav taws kub-resistant, PVC feem ntau yog siv los tsim cov vov tsev, cov ntaub thaiv dej tsis zoo, thiab cov ntaub hauv ob sab phlu. Qhov no ua rau PVC yog cov khoom siv zoo heev rau cov rooj tog zaum nraum zoov, decking, laj kab, thiab lwm yam kev siv.
Kev kho mob
PVC yog tshwj xeeb tshaj yog haum rau ntau daim ntawv thov kev kho mob vim nws cov khoom tu cev thiab tshuaj tua kab mob. Nws yog dav siv los ua cov khoom siv rau cov hnab looj tes pov tseg, aprons, thiab lwm yam khoom siv hauv kev khiav haujlwm ua yeeb yam thiab lwm qhov chaw kho mob.
Nws muaj peev xwm tiv taus cov tshuaj tua kab mob hnyav thiab tshuaj tua kab mob ua rau nws yog ib qho khoom siv zoo heev rau lub txaj pw hauv tsev kho mob, lub ntsej muag oxygen, thiab tubing. PVC kuj tseem siv rau hauv kev tsim cov tso zis tso zis, lub plawv li qub, cov hnab ntshav, thiab lwm yam khoom siv kho mob.
Automotive
PVC feem ntau pom nyob rau hauv kev tsim khoom ntawm ntau yam khoom ntawm tsheb sab hauv thiab sab nrauv. Vim nws qhov yooj yim thiab muaj peev xwm ua tau pwm, PVC yog siv los tsim cov qhov rooj, dashboards, thiab cov ntaub pua tsev.
Tsis tas li ntawd, PVC yog siv los tsim lub rooj zaum npog, lub kauj log, thiab cov iav qib npog, uas ua rau lawv xis nyob thiab yooj yim los ntxuav. PVC kuj tseem siv rau hauv kev tsim cov khoom hauv qab-lub-hood uas yuav tsum tau ua haujlwm rau qhov kub thiab txias.
Electronics
Kev lag luam hluav taws xob feem ntau siv cov khoom siv PVC rau nws cov hluav taws xob rwb thaiv tsev. Vim nws lub zog dielectric siab, PVC yog qhov kev xaiv zoo tshaj plaws rau insulating cables, uas muab hluav taws xob rwb thaiv tsev thiab tiv thaiv tib neeg los ntawm hluav taws xob phom sij.
PVC kuj tseem siv rau hauv kev tsim hluav taws xob vaj tsev, vaj huam sib luag, thiab npog, muab kev tiv thaiv los ntawm UV hluav taws xob, dej, thiab lwm yam ib puag ncig. Ntau cov khoom siv hluav taws xob xws li cov kav hlau txuas, cov tais cable, thiab cov khoom sib txuas kuj yog ua los ntawm cov khoom siv PVC.
Ntim
PVC yog ib qho khoom siv zoo heev rau kev ntim khoom vim nws cov kav ntev thiab yoog raws. Qee cov khoom ntim khoom siv PVC muaj xws li lub raj mis, ntim ntim, ntim zaj duab xis, thiab ntim khoom noj. PVC lub peev xwm los tuav nws cov duab, lub zog, thiab tiv thaiv kev ncab ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev ntim khoom uas yuav tsum muaj cov kua dej, gases, thiab lwm yam khoom.
Xaus
Cov khoom siv PVC muaj ntau daim ntawv thov thoob plaws ntau yam kev lag luam vim nws cov khoom tshwj xeeb. Nws yooj yim, muaj zog, ruaj khov, thiab yooj yim-rau-kev cai xwm ua rau nws xaiv zoo heev rau kev tsim kho, kev kho mob, tsheb, hluav taws xob, thiab kev ntim khoom. Raws li lub ntiaj teb txav mus rau cov khoom siv tau zoo, ruaj khov, thiab muaj kev nyab xeeb rau cov ntawv thov sib txawv, PVC zoo li yuav yog qhov tseem ceeb hauv ntau qhov chaw.
