Cov kav dej tawg, xws li PVC (polyvinyl chloride) thiab cpvc (cprorinated polyvinyl chloride), tau siv dav hauv cov kav dej tab sis muaj qhov sib txawv ntawm cov yeeb nkab peg. Thaum tag nrho ntawm cov ntaub ntawv no yog teastics, lawv cov khoom txawv heev, tshwj xeeb tshaj yog thaum nws los daws qhov kub thiab txias.
1. Cov txheej txheem tsim khoom
Qhov muaj teeb meem tshaj plaws ntawm GB18997 Pipes roj hmab li niaj zaus nyob hauv kev tsim khoom. Thaum PVC thiab CPVC kav yog tsim los ntawm kev kho kab ntawm polymer, PIPES dhau los sib txuas, uas txuas rau ntawm ib tus neeg polymer chains los tsim ib tug peb-seem network. Qhov network no txhim kho lub zog thiab lub zog ntawm GB18997 Cov yeeb nkab PB18997 PEX cov yeeb nkab, ua rau nws yoog tau ntau thiab tiv taus kev tawg ntawm lub siab lossis huab cua sov.
Rau pvc thiab cpvc, cov ntaub pua npab, cov polymer ua tiav linear, uas txwv lawv yooj yim thiab ua rau lawv tawg kom khov lossis muaj kev cuam tshuam ntau.
2. Yooj yooj
Ib qho ntawm cov khoom seem ntawm PEX cov yeeb nkab yog nws qhov yooj. PEX yog ntau dua yooj yim dua li cov kav dej yas tsoos, xws li PVC lossis CPVC, uas yuav tsum muaj cov fittings ntawm txhua qhov sib txuas. Qhov kev hloov pauv no tso cai rau PEX kom tau yooj yim nyob ib ncig ntawm cov fab tsis muaj kev xav tau ntxiv cov fittings ntxiv, ua kom cov teeb tsa nrawm dua thiab muaj txiaj ntsig zoo dua. Ib qho ntxiv, nws yoog tau Pex kom coiled, txo cov pob qij txha uas xav tau hauv ib qho system.
Hauv kev sib piv, PVC thiab CPVC yog tsis yeem thiab yuav tsum tau fittings rau kev hloov pauv ntawm kev coj. Qhov no ua rau kev teeb tsa ntau yam teeb meem thiab siv sijhawm ntau dua piv rau PEX.
3. Ua tsis taus
PeX kav yog paub rau lawv lub peev xwm los nthuav dav yog dej hauv lawv freezes, uas pab tiv thaiv kom txhob tawg lossis tawg. Qhov no yog vim yog lawv hloov tau yooj yim, hla cov qauv sib txuas. Thaum khov, PeX kav tuaj yeem nthuav tsis muaj tawg, thiab ib zaug dej yaj, cov yeeb nkab rov qab rau nws cov qauv qub.
Cov kav dej ua kom tsis tu ncua xws li PVC thiab CPVC, ntawm qhov tod tes, muaj kev pheej hmoo ntau rau khov. Thaum cov dej hauv cov kav dej khov, lub expansion tuaj yeem ua rau cov kav dej yuav ua rau cov kav dej kom tawg lossis tawg, ua rau muaj kev puas tsuaj thiab dej puas. Qhov no yog qhov tseem ceeb ntawm cov kav dej khov ntawm cov roj hmab yas hauv cov huab cua txias.
4. Kub tiv thaiv
PeX kav tseem paub rau lawv cov kub siab tiv thaiv qhov piv rau cov kav dej yas li niaj zaus. Cov txheej txheem sib txuas hla kev txhim kho Pex lub peev xwm los lis ob qho dej kub thiab dej txias tsis yog deforming lossis poob zog. PeX kav tau ntsuas rau cov dej kub txog 200 degree), ua rau lawv zoo tagnrho rau ntau yam ntawm cov kav dej muaj zog thiab cov dej num ua lag luam, suav nrog cov dej sov uas muaj radiant pem teb.
Pvc kav feem ntau tsuas yog ntsuas rau cov dej txias, thiab thaum CPVC tuaj yeem tswj cov dej kub, nws qhov kub tsis kam yog PEX. Tsis tas li ntawd, CPVC yog ntau dua nquag ua rau tawg thaum raug rau qhov kub thiab txias hloov.
5. Tshuaj Kuj
PeX kav muaj lub peev xwm zoo tshaj plaws los tiv thaiv kev puas tsuaj rau kev ua phem rau PVC lossis CPVC. Cov txheej txheem sib txuas hla ua rau ntau cov tshuaj muaj ntau yam, xws li chlorine, thiab lwm yam tshuaj muaj nyob hauv cov dej hauv nroog. Qhov no txhais tau tias PEX kav yog tsawg yuav tsis tshua txaus ntshai lossis tsis muaj zog nyob rau lub sijhawm thaum raug cov tshuaj no.
Hauv kev sib piv, PVC thiab CPVC muaj kev cuam tshuam ntau dua los ntawm cov tshuaj lom neeg thiab tuaj yeem tsis zoo thaum raug qee yam. Qhov no yog ib qho laj thawj yog vim li cas peox feem ntau nyiam nyob rau thaj chaw uas cov dej zoo yog kev txhawj xeeb.
Qhov zoo ntawm PEX cov yeeb nkab hla cov kav dej roj hmab niaj zaus
Lub teeb meem tshwj xeeb ntawm PEX yeeb nkab muab ob peb qhov zoo dua cov kav dej yas li qub zoo li PVC thiab CPVC. Nov yog qee cov txiaj ntsig tseem ceeb ntawm kev xaiv Pex rau cov kav dej kav dej:
1. Yooj yim ntawm kev teeb tsa
PeX kav yog qhov yooj yim dua thiab sai dua rau nruab dua cov kav dej yas tsoos vim lawv cov roj ntxiv. Txij li thaum Pex tuaj yeem bent kom haum rau cov fab tsis muaj qhov xav tau rau cov fittings, installation yog feem ntau nrawm dua thiab yuav tsum muaj tsawg dua qhov chaw. Tsis tas li ntawd, PEX tuaj yeem ntsia tau siv CRIMP, clamp, lossis laub cov txheej txheem, txhua tus yog cov neeg siv-tus phooj ywg zoo rau cov cuab yeej tshwj xeeb.
2. Yam ruaj khov
PeX kav yog cov ruaj khov thiab tiv taus rau yam uas feem ntau cuam tshuam cov kav dej roj yas. Lawv tuaj yeem tiv taus huab kub heev, ob qho tib si kub thiab txias, tsis muaj kev tawg lossis tawg. Lawv txoj kev tawm tsam kom khov ua rau lawv cov kev xaiv zoo tshaj plaws hauv huab cua nrog rau lub caij ntuj sov khov.
Tsis tas li ntawd, PEX kav yog resistant rau corrosion, nplai, thiab croundine, uas yog cov xwm txheej uas tuaj yeem ua kev puas tsuaj PVC thiab CPVC kav dhau sijhawm.
3. Txo kev pheej hmoo ntawm txi
PeX systems tsis tshua muaj peev xwm tsim kom muaj kev lom zem vim lawv qhov xwm yeem hloov tau. Tsawg dua cov pob qij txha thiab fittings xav tau, uas txo qhov peev xwm rau cov ntsiab lus tsis muaj zog uas tuaj yeem ua rau xau. Hauv kev sib piv, PVC thiab CPVC xav tau ntau dua cov fittings, uas tuaj yeem dhau los ua cov ntsiab lus ntawm lub sijhawm dhau los, tshwj xeeb tshaj yog tias cov kab ke tsis raug teeb tsa lossis raug mob hnyav.
4. Ncua sijhawm ntev dua
PeX kav feem ntau muaj lub neej ntev dua li cov kav dej yas tsoos. Vim tias lawv tiv taus corrosion, tshuaj lom neeg depadation, thiab khov, PeX system tuaj yeem nyob rau ntau caum yam tsis tas yuav hloov. PVC thiab CPVC kav, thaum tseem ruaj, yuav tsum tau hloov chaw sai, tshwj xeeb yog nyob rau hauv ib puag ncig hnyav lossis kev teeb tsa muaj kev nyuaj siab.
5. Tus nqi qis
Txawm hais tias Pex tuaj yeem kim dua PVC lossis CPVC ib txhais ko taw, cov nyiaj khaws cia hauv kev teeb tsa thiab cov haujlwm tsim txiaj hauv lub sijhawm ntev. Qhov yooj yooj ntawm Pex txo tus naj npawb ntawm fittings thiab cov pob qij txha xav tau, uas txo tus nqi rau kev teeb tsa. Ntxiv mus, lub durability ntawm Pex tuaj yeem txhais tau tias kev kho dua tsawg dua thiab hloov sijhawm thaum lub sijhawm, uas ntxiv cov nyiaj khaws nyiaj ntxiv.
Tag
Thaum cov yeeb nkab peg yog technic ib hom yas, nws tus ntoo khaub lig-txuas nws cais tawm ntawm cov kav dej yas lices zoo li pvc thiab cpvc. Cov txheej txheem hla sib txuas no muab cov kev sib txuas tshwj xeeb, suav nrog kev hloov pauv, khov kho, zoo dua tshuaj lom neeg kuj, thiab txhim kho qhov kub ntawm qhov kub. Cov khoom no ua cov kev xaiv zoo dua rau ntau qhov kev siv dej kav dej, tshwj xeeb tshaj yog thaum piv rau ntau cov kav yas loj dua.
Pex yeeb nkab ntau dua li tsuas yog yas-nws yog ntau yam, ruaj, thiab cov nqi zoo rau cov kav dej yuav tsum tau. Txawm hais tias koj hloov cov kav dej laus lossis txhim kho lub system tshiab, PEX muab kev ua tau ntev ntev nrog kev ua kom khov, xeb, lossis kev puas tsuaj. Nkag siab txog cov kev sib txawv no tuaj yeem pab koj ua qhov kev txiav txim siab paub thaum xaiv cov xa cov khoom xa khoom rau koj cov phiaj xwm txheej txheej.
