Tsis tas li ntawd, cov coatings tuaj yeem muab kev zoo nkauj zoo nkauj, tso cai rau kev hloov xim uas tuaj yeem pab txheeb xyuas cov kav dej lossis cov tshuab. Tsis tas li ntawd, qee cov coatings tuaj yeem txo qhov kev sib txhuam, txhim kho cov yam ntxwv ntawm cov dej hauv kev siv dej. Qhov kev sib xyaw ua ke ntawm cov txiaj ntsig no ua rau coatings ib qho kev xaiv zoo nkauj rau cov tuam txhab nrhiav kev ua kom zoo dua ntawm PPH fittings.
Kev siv hauv ntau yam kev lag luam
PPH fittings nrog coatings pom cov ntawv thov hauv ntau qhov kev lag luam, suav nrog kev ua tshuaj, kev kho dej, thiab kev tsim kho. Hauv kev lag luam tshuaj, qhov twg raug cov kuab tshuaj hnyav heev, cov txheej txheem tuaj yeem muab cov txheej txheem ntxiv ntawm kev tiv thaiv corrosion thiab degradation. Hauv cov chaw kho dej, coated PPH fittings yog qhov tseem ceeb rau kev tswj xyuas kev nyiam huv thiab tiv thaiv kev sib kis, vim qee cov txheej txheem tsim los tiv thaiv kev loj hlob ntawm cov kab mob thiab biofilms. Tsis tas li ntawd, nyob rau hauv kev tsim kho kev siv, kev zoo nkauj thiab kev tiv thaiv zoo ntawm cov coatings txhim khu kev ruaj khov thiab pom kev pom ntawm PPH fittings siv hauv cov kav dej thiab cov kav dej.
Kev sib tw hauv Txheej PPH Fittings
Txawm hais tias qhov zoo, txheej PPH fittings los nrog nws tus kheej cov teeb meem. Ib qho ntawm cov kev txhawj xeeb tseem ceeb yog qhov adhesion ntawm txheej rau PPH nto, uas tuaj yeem cuam tshuam los ntawm yam xws li kev npaj nto thiab hom txheej siv. Kev tu kom zoo thiab priming yog qhov tseem ceeb los xyuas kom muaj zog adhesion thiab tiv thaiv delamination. Tsis tas li ntawd, cov khoom siv thermal ntawm PPH tuaj yeem tsim teeb meem, vim qee cov txheej txheem yuav tsis tuaj yeem tiv taus qhov kub thiab txias thaum ua haujlwm lossis hauv kev pabcuam. Cov neeg tsim khoom yuav tsum ua tib zoo xav txog cov teeb meem no los xaiv cov khoom tsim nyog thiab cov txheej txheem uas ua kom ntseeg tau tias cov khoom siv coated fittings.
Xaus
Hauv kev xaus, cov txheej txheem txheej siv rau PPH fittings ua lub luag haujlwm tseem ceeb hauv kev txhim kho lawv cov kev ua tau zoo thiab nthuav lawv cov kev siv tau thoob plaws ntau yam kev lag luam. Los ntawm kev nkag siab txog cov txheej txheem txheej txheej sib txawv thiab lawv cov txiaj ntsig, cov tuam txhab tuaj yeem txhim kho PPH fittings rau cov kev xav tau tshwj xeeb, txawm tias kev txhim kho tshuaj tiv thaiv, kev zoo nkauj, lossis kev ua haujlwm zoo. Raws li kev lag luam txuas ntxiv mus ntxiv, qhov tseem ceeb ntawm cov txheej txheej hauv kev ua kom muaj peev xwm ntawm PPH fittings yuav dhau los ua qhov tseem ceeb, kom ntseeg tau tias cov khoom siv ntau yam ua tau raws li qhov xav tau ntawm cov ntawv thov niaj hnub no.
