PVC, lub npe tag nrho polyvinyl chloride, kuj yog ib yam khoom yas.
PVC ua li cas?
Nws tuaj yeem pom los ntawm nws lub npe Suav polyvinyl chloride tias nws cov ntaub ntawv raw yog chlorine thiab ethylene. Ethylene kuj yog cov khoom siv raw rau kev tsim cov ethylene glycol thiab polyethylene. Lub hauv paus ntawm ethylene yog natural gas thiab crude roj; Lub hauv paus ntawm chlorine yog los ntawm cov dej ntsev thiab lub rooj ntsev. Cov khoom tseem ceeb yog sodium chloride. Cov roj chlorine tuaj yeem tau los ntawm electrolysis, thiab tom qab ntawd cov roj chlorine thiab ethylene yog siv los npaj polyvinyl chloride. Txoj kev no hu ua ethylene method.
Txoj kev calcium carbide, lwm cov txheej txheem ntawm PVC, yog npaj siv raw cov ntaub ntawv acetylene ntsev thiab muaj chloride. Cov khoom siv raw ntawm ethyl sulfate yog calcium carbide, thiab qhov chaw yog thee.
Ob txheej txheem yog nyob rau hauv txawv kev loj hlob lub neej voj voog, thiab lub expansion tank yog kev lag luam. Nyob rau hauv qhov tseeb, nws yog tus nqi kom zoo dua ntawm cov tuam txhab uas muaj lawv tus kheej lub hwj chim noj nyob rau hauv zus tau tej cov calcium carbide txoj kev uas cuam tshuam.
Cov chaw twg PVC ua si?
