CPVC thiab CPVC CTSnyob rau hauv Kev Siv Hluav Taws Xob
Raws li peb tau hais, peb muaj kev tsis ncaj ncees me ntsis rau PVC, tab sis qhov ntawd tsis tau txhais hais tias peb tsis paub lwm yam khoom zoo thaum peb pom lawv - xws li CPVC thiab CPVC CTS.Ob yam khoom zoo ib yam li PVC, tab sis lawv muaj qee qhov zoo.

CPVC yog chlorinated PVC (qhov no yog qhov ntxiv C los ntawm).CPVC yog ntsuas rau 200 ° F, ua rau nws yog thawj qhov kev xaiv rau kev siv dej kub.Ib yam li PVC yeeb nkab, CPVC yog ib qho yooj yim rau nruab, ruaj thiab yuav tsum tau saib xyuas me ntsis.

Ob leeg PVC thiab CPVC siv tib daim ntawv loj, uas tsis sib xws nrog cov yeeb nkab tooj liab.Rau feem ntau ntawm 20th thiab thaum ntxov 2000s, cov yeeb nkab tooj liab yog cov yeeb nkab uas xaiv rau cov kav dej.Koj tsis tuaj yeem siv PVC lossis CPVC hauv koj cov yeeb nkab tooj liab vim qhov sib txawv me me, qhov ntawd yog qhov CPVC CTS los rau hauv. CPVC CTS yog CPVC hauv cov yeeb nkab tooj liab.Cov kav dej no tau tsim zoo li CPVC thiab tuaj yeem siv nrog cov kav dej tooj liab thiab fittings.

Vim li cas koj yuav tsum siv PVC yeeb nkab
