Taw qhia
Cov txheej txheem dej yog ib qho tseem ceeb ntawm lub neej niaj hnub, muab dej huv thiab siv tau rau cov tsev, kev lag luam, thiab kev lag luam. Ib qho kev txiav txim siab tseem ceeb hauv kev tsim thiab tsim cov khoom siv dej yog kev xaiv cov khoom siv yeeb nkab. Ntawm cov khoom siv yeeb nkab nrov muaj, polyethylene (PEX) thiab polyvinyl chloride (PVC) cov kav dej feem ntau siv rau hauv cov kav dej. Daim ntawv no muab ibnkag siabsive kev sib piv ntawm PEX thiab PVC kav los txheeb xyuas qhov twg yog qhov kev xaiv zoo dua rau cov kav dej.
PEX Pipes
PEX cov kav dej yog tsim los ntawm kev sib txuas ntawm polyethylene, cov khoom siv yas uas muaj peev xwm tswj tau qhov kub thiab txias. PEX cov kav dej yog lub teeb yuag, yoog raws, thiab yooj yim rau nruab, ua rau lawv muaj kev xaiv nrov rau ob qho tib si hauv tsev thiab kev lag luam dej. Qhov txiaj ntsig tseem ceeb ntawm cov kav dej PEX yog lawv lub peev xwm nthuav dav thiab cog lus nrog kev hloov pauv ntawm qhov kub thiab txias, txo qhov muaj feem cuam tshuam los yog tawg vim yog khov lossis lwm yam mob hnyav.
Qhov zoo ntawm PEX Pipes
1. Flexibility: PEX cov kav dej hloov tau yooj yim, ua rau lawv yooj yim rau nruab thiab khoov nyob ib puag ncig cov teeb meem xws li cov ces kaum lossis qhov chaw nruj yam tsis tas yuav tsum muaj cov fittings ntxiv.
2. Corrosion kuj: PEX cov kav dej yog cov resistant rau corrosion, ua rau lawv nyob ntev thiab zoo tagnrho rau siv nyob rau hauv cov cheeb tsam uas muaj acidity siab.
3. Thermal resistance: PEX cov kav dej tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj kev tawg lossis tawg, ua rau lawv haum rau siv hauv cov dej kub.
Cov kav dej PVC
Cov kav dej PVC yog tsim los ntawm Polyvinyl Chloride, cov khoom siv yas paub txog nws cov kav ntev thiab tsis kam rau cov tshuaj hnyav. Cov kav dej PVC feem ntau yog siv rau cov khoom siv dej vim lawv lub zog, tus nqi qis, thiab kev yooj yim ntawm kev teeb tsa. Tsis zoo li PEX cov kav dej, cov kav dej PVC yog nruj thiab hloov tsis tau thiab xav tau cov khoom siv ntxiv rau kev taw qhia cov ces kaum lossis nyob ib puag ncig lwm yam teeb meem.
Qhov zoo ntawm cov yeeb nkab PVC
1. Kev them taus: cov kav dej PVC kuj pheej yig dua piv rau lwm cov khoom siv yeeb nkab.
2. Lub zog: PVC cov kav dej muaj zog thiab ruaj khov, tiv taus deformation thiab tawg, txawm tias nyob rau hauv siab.
3. Tshuaj tiv thaiv: PVC cov kav dej tiv taus ntau yam tshuaj hnyav uas feem ntau pom nyob rau hauv cov kav dej.
Kev sib piv ntawm cov kav dej PEX thiab PVC kav dej rau cov kav dej
1. Durability: Ob lub kav dej PEX thiab PVC kav yog paub txog lawv cov kav ntev thiab ntev. Txawm li cas los xij, PEX cov kav dej zoo li muaj qhov ua tau zoo dua rau qhov kub thiab txias thiab thermal expansion / contraction, ua rau lawv tsis tshua muaj dej los yog tawg.
2. Kev txhim kho: PEX cov kav dej yog yooj yim rau nruab, yuav tsum muaj tsawg dua fittings thiab cov khoom sib txuas, thiab tuaj yeem khoov ib ncig ntawm cov teeb meem, txo qhov kev pheej hmoo ntawm kev xau vim cov pob qij txha tsis muaj zog lossis nkig. PVC kav, ntawm qhov tod tes, yuav tsum tau ntxiv fittings, connectors, thiab nplaum rau nruab, ua rau lawv ntau zog-intensive.
3. Tus nqi: PVC cov kav dej feem ntau tsis tshua kim tshaj cov kav dej PEX, ua rau lawv xaiv zoo rau cov neeg tsim khoom siv nyiaj txiag lossis cov tswv tsev.
4. Kev cuam tshuam ib puag ncig: PVC cov kav dej yog tsim los ntawm cov khoom siv hluavtaws, uas ua rau muaj kev txhawj xeeb txog lawv qhov cuam tshuam rau ib puag ncig. Hauv qhov sib piv, PEX cov kav dej tsis muaj cov tshuaj phem, ua rau lawv muaj kev xaiv zoo dua thiab muaj txiaj ntsig zoo.
Xaus
Hauv kev xaus, ob qho tib si PEX thiab PVC kav muaj lawv qhov zoo thiab qhov tsis zoo, ua rau lawv tsim nyog rau kev siv dej sib txawv. Rau cov neeg siv nyiaj, cov kav dej PVC feem ntau yog qhov kev xaiv zoo dua vim lawv pheej yig, ua haujlwm ntev, thiab tsis kam rau cov tshuaj hnyav. Rau cov neeg uas tab tom nrhiav kev xaiv ntau dua hauv eco-phooj ywg lossis rau thaj chaw uas muaj qhov hnyav ib puag ncig, PEX cov kav dej 'kev ua haujlwm zoo dua thiab ua kom yooj yim ua rau lawv xaiv zoo dua. Thaum kawg, kev xaiv cov khoom siv yeeb nkab yuav nyob ntawm ntau yam xws li kev ua haujlwm, kev ua haujlwm ntev, kev teeb tsa tus nqi, thiab qhov tseem ceeb tshaj plaws, ib puag ncig, thiab lwm yam.
