Vim li cas PVC siv hauv kev tsim kho los ntawm ntau tus neeg tam sim no? Nws qhov zoo yog dab tsi?

Muaj ntau qhov laj thawj vim li cas PVC (polyvinyl chloride) tau siv ntau dua hauv kev tsim kho.
Ua ntej ntawm tag nrho cov, PVC yog ib qho khoom siv rau ib puag ncig. Piv nrog cov tsoos ntoo thiab hlau, nws cov txheej txheem ntau lawm ua rau muaj kuab paug tsawg dua rau ib puag ncig thiab rov ua dua tshiab, raws li cov neeg niaj hnub niaj hnub nrhiav kev tiv thaiv ib puag ncig.
Thib ob, PVC yog cov khoom siv ruaj khov uas tsis muaj dej tsis zoo, tsis muaj dej tsis zoo, tiv thaiv corrosion thiab tsis-flammable. Nws yog dav siv hauv kev tsim cov phab ntsa sab nrauv, ru tsev, pem teb, phab ntsa vaj huam sib luag, qhov rooj thiab qhov rais, thiab lwm yam. Cov khoom siv hauv tsev ua los ntawm PVC muaj lwm yam zoo dua li kev tiv thaiv ib puag ncig thiab ruaj khov. Lawv yog cov hnyav heev thiab yooj yim los tuav thiab txhim kho, ua rau kev tsim kho ntau dua. Qhov saum npoo ntawm cov khoom siv PVC yog cov dej tsis muaj dej thiab yuav tsis raug puas los ntawm qhov chaw ntub dej lossis dej corrosion.
Tsis tas li ntawd, cov khoom siv hauv tsev PVC muaj ntau hom thiab cov lus qhia tshwj xeeb thiab tuaj yeem ua tau raws li cov kev xav tau sib txawv ntawm cov neeg siv khoom, yog li lawv muaj kev lag luam dav dav. PVC cov ntaub ntawv hauv tsev kuj muaj cov haujlwm ntawm lub suab rwb thaiv tsev thiab kev txuag hluav taws xob. Cov khoom siv hauv tsev xws li PVC qhov rooj thiab qhov rais muaj cov suab rwb thaiv tsev zoo dua li cov qhov rais ntoo lossis aluminium alloy qhov rais thiab tuaj yeem txo kev cuam tshuam los ntawm cov suab nrov sab nraud. PVC kuj tseem yog cov khoom siv hluav taws xob tsawg thermal conductivity, uas tuaj yeem txo cov cua sov ntawm cov tsev, yog li txo cov kev siv hluav taws xob.
Tsis tas li ntawd, tus nqi saib xyuas ntawm PVC kuj tsawg heev, thiab nws tsis tas yuav tsum tau tu thiab tu, txuag nyiaj thiab siv zog. Qhov tseem ceeb tshaj plaws yog vim tias PVC cov ntaub ntawv hauv tsev yog cov khoom siv hluavtaws, lawv yuav tsis nqus dej los yog deform, kom tsis txhob muaj qee qhov tsis xws luag uas yuav tshwm sim hauv cov ntaub ntawv ntuj xws li ntoo.
