Kev hloov pauv ntawm PEX Cov kav dej hauv cov kav dej niaj hnub
Ob peb lub xyoo dhau los, PEX (cross-linked polyethylene) cov kav dej tau tshwm sim los ua kev hloov pauv hauv kev lag luam kav dej, muab qhov tsis sib xws, kev ua haujlwm ntev, thiab kev siv nyiaj txiag. Lawv cov kev taw qhia tau cim qhov kev hloov pauv tseem ceeb ntawm cov khoom siv ib txwm muaj xws li tooj liab thiab galvanized steel, muab kev xaiv ntau dua thiab txhim khu kev qha rau ntau yam kev siv.
PEX cov kav dej yog tsim los ntawm cov txheej txheem uas cuam tshuam nrog kev sib txuas ntawm polyethylene molecules, ua rau cov khoom siv tuaj yeem tiv taus qhov kub thiab txias, kev kub ntxhov, thiab ib puag ncig. Cov txheej txheem no ua kom cov kav dej muaj zog tiv taus cov kab nrib pleb, xau, thiab tawg, txawm tias muaj teeb meem nyuaj.
Ib qho ntawm qhov zoo tshaj plaws ntawm cov kav dej PEX yog lawv qhov yooj yim. Tsis zoo li cov kav dej tsis sib haum, PEX tuaj yeem yooj yim ua haujlwm nyob ib puag ncig ntawm cov ces kaum thiab cov teeb meem, txo qhov xav tau ntawm cov fittings thiab cov ntsiab lus xau. Qhov no tsis tsuas yog ua rau kev txhim kho sai thiab yooj yim dua, tab sis kuj tseem txhim kho kev ntseeg tau ntev ntawm cov kav dej.
Hais txog tus nqi, PEX cov kav dej muaj kev txuag nyiaj ntau dua piv rau lawv cov khoom siv ib txwm muaj. Cov khoom nws tus kheej yog pheej yig dua, thiab txo lub sij hawm installation thiab nqi zog ua rau tag nrho cov nqi-zoo. Tsis tas li ntawd, kev txuag hluav taws xob tau ua tiav vim PEX cov khoom siv thermal zoo ntxiv ua pov thawj rau thawj zaug peev.
Txawm hais tias muaj ntau yam txiaj ntsig, nws tseem ceeb heev kom lees paub tias cov kav dej PEX tsis yog yam tsis muaj kev txwv. Lawv rhiab heev rau UV raug thiab tej yam tshuaj, yuav tsum tau ceev faj tuav thiab installation xyaum. Txawm li cas los xij, nrog kev saib xyuas kom raug thiab ua tib zoo saib xyuas kom meej, PEX kav dej tuaj yeem muab cov kav dej muaj zog thiab siv tau zoo, ua kom zoo dua cov khoom siv hauv kev ua haujlwm thiab kev ua haujlwm ntev.
