Ib lub sijhawm zoo tshaj plaws hauv tib neeg keeb kwm yog qhov tshwm sim ntawm cov kav dej hauv tsev. Cov kav dej hauv tsev tau nyob thoob ntiaj teb txij li xyoo 1840, thiab ntau yam khoom siv tau siv los muab cov kav dej. Nyob rau hauv xyoo tas los no, cov kav dej PVC tau dhau los ua ntau dua thiab nrov dua li cov kav dej tooj liab yog thawj qhov kev xaiv rau cov kav dej hauv tsev. PVC yog ruaj, pheej yig, thiab yooj yim rau nruab, cementing nws txoj hauj lwm ua ib qho kev xaiv zoo tshaj plaws rau cov kav dej.

Qhov zoo ntawm kev siv PVC hauv cov kav dej
Cov kav dej PVC tau nyob ib puag ncig txij li xyoo 1935 thiab pib siv rau cov kav dej khib nyiab-qhov cua thaum rov tsim kho tom qab Tsov Rog Ntiaj Teb Zaum II. Nws tsuas yog loj hlob nyob rau hauv muaj koob meej txij thaum ntawd los thiab tau dhau los ua qhov kev xaiv zoo tshaj plaws rau cov kav dej thoob ntiaj teb. Thiab, txawm hais tias peb yuav muaj kev tsis ncaj ncees me ntsis, nws yooj yim pom vim li cas qhov no yog qhov teeb meem.

PVC yog ib qho ntawm cov khoom siv kim tshaj plaws hauv kev ua lag luam niaj hnub no. Tsis tas li ntawd xwb, tab sis nws yog lub teeb yuag, ruaj thiab yooj yim rau nruab.PVC cevtuaj yeem tiv taus kub txog 140 ° thiab tuaj yeem tiv taus siab txog 160psi. Zuag qhia tag nrho, nws yog ib qho khoom siv zoo heev. Nws yog abrasion thiab tshuaj resistant thiab tuaj yeem tiv taus ntau yam huab cua sib txawv. Tag nrho cov no ua ke los ua PVC cov khoom siv ruaj khov uas tuaj yeem kav ntev txog 100 xyoo. Tsis tas li ntawd, cov kev hloov tsis tu ncua no pab txo qhov cuam tshuam ib puag ncig.

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 lag luam 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 ntawm kev xaiv 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
Cov kav dej yog qhov tseem ceeb ntawm txhua lub tsev lossis kev lag luam, thiab nws raug nqi ntau heev. Los ntawm kev siv cov kav dej PVC, koj tuaj yeem txuag koj tus kheej cov nqi kho thiab cov nqi ua ntej ntawm cov kav hlau. Nrog nws tsis kam mus rau tshav kub, siab thiab tshuaj lom neeg, nws cov peev txheej yuav kav mus ib txhis.
