Taw qhia
PPR (polypropylene random copolymer) fittings feem ntau siv hauv cov kav dej vim lawv hnav, ruaj, thiab corrosion-resistant. Txawm li cas los xij, kev txhawj xeeb tau hais txog qhov muaj feem cuam tshuam uas PPR fittings yuav muaj rau cov dej zoo uas ntws los ntawm lawv. Hauv tsab xov xwm no, peb yuav tshawb xyuas seb PPR fittings puas muaj kev cuam tshuam rau cov dej zoo, thiab yog tias muaj, cov teebmeem no yuav ua li cas.
Cov khoom sib xyaw ntawm PPR Fittings
PPR fittings yog tsim los ntawm cov thermoplastic resin hu ua polypropylene. Cov resin yog ua tiav nrog cov txheej txheem copolymer random uas suav nrog qhov sib ntxiv ntawm ethylene monomer, uas txhim kho cov khoom siv lub zog thiab hloov tau yooj yim. PPR fittings yog tsim los tiv taus qhov kub thiab txias thiab yog qhov kev xaiv zoo tshaj plaws rau kev siv dej kub thiab cua sov.
Lub peev xwm cuam tshuam ntawm PPR Fittings ntawm Dej Zoo
Kev tshawb fawb tau pom tias PPR fittings yuav muaj qee yam cuam tshuam rau cov dej zoo. PPR fittings tuaj yeem ua rau muaj tshuaj lom neeg hauv dej, uas ua rau muaj qee yam tshuaj lom neeg, xws li txhuas thiab tooj liab, hauv dej. Cov leaching ntawm cov tshuaj los ntawm cov fittings rau hauv dej tuaj yeem tshwm sim los ntawm ntau yam, xws li qhov kub thiab txias ntawm cov dej, nrog rau qhov zoo ntawm qhov haum nws tus kheej.
Cov kev tshawb fawb tau pom tias PPR fittings tuaj yeem tso cov tshuaj xws li bisphenol-A (BPA), txhuas, thiab tooj liab rau hauv dej. BPA yog ib qho tshuaj uas feem ntau siv los tsim cov yas polycarbonate thiab epoxy resins. BPA yog tus paub txog endocrine cuam tshuam thiab tuaj yeem ua rau tib neeg noj qab haus huv yog tias noj ntau ntau. Cov hmoov txhuas kuj yog cov tshuaj txaus ntshai uas tuaj yeem pom muaj nyob hauv qee qhov PPR fittings, thiab nws cov khoom noj tuaj yeem ua rau muaj teeb meem loj, tshwj xeeb tshaj yog rau cov menyuam yaus.
Muaj peev xwm cuam tshuam txog kev noj qab haus huv cuam tshuam nrog PPR Fittings
Qhov cuam tshuam txog kev noj qab haus huv cuam tshuam nrog PPR fittings tuaj yeem loj heev, tshwj xeeb tshaj yog tias lawv tsis raug ntsia kom raug lossis raug ntsuas tsis tu ncua rau hnav thiab tsim kua muag. Kev noj cov dej uas muaj cov tshuaj phem tuaj yeem ua rau muaj teeb meem kev noj qab haus huv, suav nrog teeb meem plab hnyuv thiab lub siab, txo lub raum ua haujlwm, thiab mob qog noj ntshav.
Cov qauv kev cai rau PPR Fittings
Cov koom haum tswj hwm hauv ntau lub tebchaws tau teeb tsa cov qauv tsim thiab teeb tsa PPR fittings los tiv thaiv pej xeem kev noj qab haus huv thiab kev nyab xeeb. Cov qauv no suav nrog cov txheej txheem kev soj ntsuam nruj uas ntsuas qhov zoo thiab kev nyab xeeb ntawm cov fittings, theem ntawm leaching ntawm cov tshuaj phem, thiab qhov cuam tshuam ntawm yam xws li kub thiab siab ntawm cov dej zoo.
Xaus
PPR fittings feem ntau siv hauv cov kav dej vim lawv lub teeb yuag, ruaj khov, thiab tiv taus corrosion. Txawm hais tias PPR fittings feem ntau suav hais tias muaj kev nyab xeeb, kev tshawb fawb tau pom tias lawv tuaj yeem cuam tshuam cov dej zoo thiab tuaj yeem tso cov tshuaj phem xws li BPA, txhuas, thiab tooj liab rau hauv dej. Yog li, nws raug pom zoo tias PPR fittings raug ntsia kom raug, soj ntsuam tsis tu ncua rau hnav thiab tsim kua muag, thiab hloov yog tias tsim nyog. Nws tseem yog ib qho tseem ceeb uas yuav tau xaiv cov fittings uas ua tau raws li cov qauv kev tswj hwm kom ntseeg tau tias lawv tsis ua rau muaj kev phom sij rau pej xeem kev noj qab haus huv lossis ib puag ncig.
