cov khoom siv
Ob cov ntaub ntawv zoo sib xws vim lawv cov khoom siv tau yooj yim, tab sis lawv cov khoom sib xyaw, daim ntawv thov thiab kev teeb tsa sib txawv heev.Peb mam li pib los ntawm kev saib cov khoom.PEX stands rau cross-linked polyethylene.Nws yog ua los ntawm high-density polyethylene nrog cross-linked bonds nyob rau hauv lub polymer qauv.Nws suab nyuaj, tab sis nws tsuas yog txhais tau hais tias cov khoom siv hloov pauv tau thiab tuaj yeem tiv taus qhov kub siab (txog 180F rau kev siv kav dej).

Saj zawg zog PVC yog tsim los ntawm tib yam khoom siv li niaj zaus PVC: polyvinyl chloride.Txawm li cas los xij, plasticizers tau ntxiv rau qhov sib xyaw kom nws yooj yim.Saj zawg zog PVC tuaj yeem tiv taus qhov kub ntawm -10F txog 125F, yog li nws tsis haum rau cov dej kub.Txawm li cas los xij, nws muaj txiaj ntsig zoo hauv ntau daim ntawv thov, uas peb yuav npog hauv ntu tom ntej.

daim ntawv thov
Qhov sib txawv ntawm ob lub kav dej yog ntau dua li lawv cov qauv.Lawv kuj tau siv rau hauv daim ntawv thov sib txawv kiag li.PEX yeeb nkab feem ntau yog siv hauv cov kav dej hauv tsev thiab kev lag luam vim nws qhov chaw me me thiab qhov kub tsis kam.PEX yog qhov zoo tshaj plaws rau cov haujlwm no vim tias nws tuaj yeem khoov tau yooj yim thiab khoov rau txhua qhov kev taw qhia yam tsis tas siv ntau yam khoom siv.Nws yooj yim rau nruab dua li tooj liab, uas tau ua tus qauv dej kub rau ntau tiam neeg.

Cov yeeb nkab PVC yooj yooj yim yuav tsis tuav dej kub, tab sis nws muaj lwm yam zoo.Nws cov txheej txheem thiab tshuaj toughness ua kom yoog raws PVC zoo tagnrho rau cov pas dej da dej thiab dej.Cov tshuaj chlorine siv rau cov dej hauv pas dej ua rau muaj kev cuam tshuam me ntsis ntawm cov yeeb nkab tawv no.Flex PVC kuj yog qhov zoo rau kev ua dej hauv vaj, vim nws tuaj yeem ua rau txhua qhov chaw koj xav tau yam tsis muaj kev cuam tshuam ntau ntxiv.

Raws li koj tuaj yeem pom, piv PEX yeeb nkab rau PVC hloov tau zoo li pitting pab pawg ntaus pob ntaus pob hockey.Lawv txawv heev, lawv sib tw tsis tau!Txawm li cas los xij, qhov no tsis yog qhov sib txawv kawg.Peb mam li saib ib qho ntawm cov yam ntxwv tseem ceeb ntawm txhua hom yeeb nkab: kev teeb tsa.Nyeem ntxiv txog PEX apps hauv kab lus no los ntawm Tsev Neeg Handyman.
