Taw qhia: Tus txias - huab cua camer rau pvc
Polyvinyl chloride (PVC) cov yeeb nkab fittings tau siv dav hauv cov kav dej, dej, thiab kev lag luam tiv thaiv, thiab yooj yim ntawm kev teeb tsa. Txawm li cas los xij, ib qho ntawm tus tseem ceeb cov nyom pvc ntsej muag yog nws tau txais tus kheej brittleness ntawm tsawg kub. Raws li kub hnyiab, qhov cuam tshuam tsis ntawm daim ntawv los ntawm daim ntawv los ntawm pvc txo qis, muaj peev xwm ua rau tawg lossis ua tsis tiav. Cov ntawv no tshawb nrhiav txog kev tsim kho niaj hnub no thiab tsim kev txhim kho pab PVC fittings ua tau zoo dua hauv ib puag ncig txias.
Nkag siab txog qhov ua rau muaj qis - kub tawm
Ntawm qis dua kub, pvc dhau los ua kom nruj vim txo cov lus qhia molecular nyob hauv nws cov saw polymer. Qhov no rigidity txwv cov khoom siv muaj peev xwm nqus lub zog los ntawm cov rog sab nraud. Raws li qhov tshwm sim, fittings nthuav tawm kev cuam tshuam lossis siab hloov pauv yog ntau dua nquag ua rau tawg. Tsawg - kub brittleness yog qhov kev txhawj xeeb tseem ceeb hauv sab nraum zoov lossis tsis muaj kev sib koom ua ke, tshwj xeeb hauv huab cua sab qaum teb lossis thaum lub caij ntuj no.
Cov Khoom Siv Ua Qauv thiab Ntxiv
Txhawm rau tawm tsam Brittleness, cov chaw tsim khoom lag luam feem ntau hloov kho tus PVC sib txuas los ntawm Acrylonitrile (ABS) lossis crocorinated polyethylene (CPE). Cov khoom ntxiv no txhim kho cov khoom siv hloov thiab tawv hauv qab txias. Kev siv cov plyasizers hauv qee hom pvc yam, tshwj xeeb tshaj yog nyob rau hauv tsis- qhov kev siv siab, tseem txhawb tau kev txhim kho kev ua tau zoo ntawm qhov chaw kub qis dua.
Tsim cov yam ntxwv uas txhim kho txias tsis kam
Cov geometry ntawm ib tug PVC phim kuj tseem tuaj yeem cuam tshuam nws qhov kev ua tau zoo hauv cov chaw txias. Cov fittings nrog du curves thiab thickened cov ntsiab lus tsis tshua muaj zog rau kev ntxhov siab lub siab, txo qhov ntxim nyiam ntawm kev tawg. Tsis tas li ntawd, qhov chaw thiab xov tsim qauv uas ua tib zoo faib kev pab tiv thaiv kev tiv thaiv tawg rog thaum lub thermal meraction. Cov Phab Ntsa kom zoo thiab cov kev tsim kev lag luam tsis sib xws ntxiv txhim kho kev ntseeg siab.
Kev ua zoo tshaj plaws rau kev txhim kho huab cua
Txawm hais tias nrog cov ntaub ntawv txhim kho thiab tsim qauv, cov txheej txheem daws teeb meem yog qhov tseem ceeb. Cov ntaub ntawv yuav tsum zam kev siv cov quab yuam ntau dhau thaum sib dhos thiab yuav tsum tau tiv thaiv kev tawm tsam lossis khob qhov chaw sov, tshwj xeeb yog qis dua 5℃(41℃(41℃f). Ua ntej {{4 {}}}} sov sov fittings lossis khaws cia rau hauv ib puag ncig rhuab ua ntej siv kuj tuaj yeem txo kev pheej hmoo ntawm kev puas tsuaj. Nws tseem tab tom muaj kev pom zoo los siv cov kuab tshuaj uas tsim rau txias- cov duab thov huab cua, raws li cov qauv nplaum ua tsis tiav.
Xaus: Txhim Kho Kev Ntseeg Txog Hauv Kev Nyab Xeeb
PVC cov yeeb nkab fittings tau hloov zuj zus los ua kom zoo dua nrog cov kev cov nyom uas tsis muaj tsawg -} qhov chaw ib puag ncig. Los ntawm cov khoom kom zoo, tsim qauv ntse, thiab cov tswv yim tsim nyog, cov cuab yeej siv kom ruaj khov, muaj cov huab cua sov} {}} qhov tsis ua haujlwm. Rau cov ntawv tseem ceeb, xaiv cov fittings tau ntawv pov thawj rau qis- kub siv ua kom muaj kev sib haum xeeb thiab kev thaj yeeb ntawm lub siab.
