Qhov kub hloov pauv cuam tshuam li cas rau PPR fittings?
Dec 07, 2023
Raws li tus neeg sawv cev ntawm IFAN, Kuv tuaj yeem hais txog qhov kub thiab txias npaum li cas cuam tshuam rau PPR (Polypropylene Random Copolymer) fittings:
Thermal Expansion thiab Contraction: PPR muaj cov coefficient ntawm thermal expansion dua hlau. Qhov no txhais tau tias nws nthuav ntau nrog cua sov thiab cog lus ntau dua thaum txias. Kev txhim kho kom zoo yuav tsum suav rau qhov no txhawm rau tiv thaiv kev ntxhov siab ntawm cov fittings.
Kub Resilience: PPR fittings tuaj yeem tiv taus ntau yam kub, feem ntau ntawm -20 degree mus rau 95 degree, ua rau lawv haum rau ob qho tib si txias thiab dej kub.
Cov Teeb Meem Ntev Ntev: Kev raug kub hnyiab tas mus li tuaj yeem cuam tshuam rau lub neej ntawm PPR fittings, uas ua rau lawv nkig ntau dhau sijhawm.
Kev sib koom ua ke: Qhov kub thiab txias tuaj yeem cuam tshuam cov pob qij txha ntawm PPR fittings. Kev sib koom ua ke kom zoo yog qhov tseem ceeb los xyuas kom muaj kev ruaj ntseg, xau-pov thawj system.
Siab Variations: Raws li qhov kub thiab txias cuam tshuam qhov siab hauv cov kav dej, PPR fittings yuav tsum tau ntsuas los tswj cov kev hloov siab no.
Tshuaj Stability: PPR tuav nws cov tshuaj tiv thaiv thoob plaws nws qhov kev khiav hauj lwm kub, kom tsis txhob muaj leaching lossis degradation.
UV Sensitivity: PPR fittings tuaj yeem nkag siab rau UV hluav taws xob, thiab qhov ntev ntawm lub hnub tuaj yeem cuam tshuam rau lawv cov kav ntev.
Rwb thaiv tsev yuav tsum tau: Nyob rau hauv ib puag ncig uas muaj qhov kub thiab txias hloov pauv, kev rwb thaiv tsev ntxiv yuav tsum tau ua kom muaj kev ncaj ncees ntawm PPR system.
Zuag qhia tag nrho, thaum PPR fittings muaj zog thiab hloov tau rau ntau qhov kub thiab txias, kev nkag siab thiab kev npaj rau cov teebmeem no thaum lub sijhawm teeb tsa thiab siv yog qhov tseem ceeb rau kev ua haujlwm ntev thiab kev nyab xeeb.
