Cim cov txiaj ntsig ntawm PEX khoom nyob rau hauv cov roj nyob rau hauv cov roj: qhov zoo tshaj plaws ntawm corrosion tsis kam thiab yooj

Lub hauv paus rau phau ntawv

Nyob rau hauv lub realm faib cov tshuab, kev xaiv cov khoom siv rau cov kev cuam tshuam ncaj qha cuam tshuam kev nyab xeeb ncaj ncees, kev ua haujlwm ruaj khov, thiab ua haujlwm ua haujlwm. Hla-txuas Polyethylene (PeX) tau tawm los ua cov khoom siv hloov pauv rau corrosion tsis kam thiab yoog raws li cov hlau ib txwm ua tsis tau. Cov ntawv no tshawb txog li cas pex cov khoom nyob ntawm cov qauv roj tseem ceeb, tshem tawm mus rau hauv nws cov ntawv thov kev ua tau zoo, thiab yav tom ntej thev naus laus zis.

Cov qauv molecular thiab corrosion resistance tshuab

Hla-Txuas Polyethylene Architecture

PEX ua ib qho kev sib tw peb-seem los ntawm kev sib txuas nrog cov saw polyethylene chains, feem ntau ntawm:

Cov Silane Cross-Txuas (PEX-B): Tsim cov hlua khi ntawm cov saw hlau uas siv noo noo-kho kom zoo-ua rau muaj kev sib tw, ua rau muaj kev sib tw.

Electron txig irradiation (PeX-c): Siv cov hluav taws xob siab rau cov hluav taws xob hluav taws xob kom tsis sib xws, ua tiav 70-75 qhov ceev nrog cov kev faib tawm tsis zoo.

Cov qauv network no muab cov kev lag luam tsis kam los ntawm:

Thaiv kev doltusion paths: The cross-linked matrix reduces gas and liquid permeation by 30-40% compared to linear polyethylene.

Tshuaj lom neeg inertness: Polyethylene tsis yog-polar qauv tiv thaiv tawm tsam los ntawm feem ntau acids, alkalis, thiab ntsev pom hauv cov roj ntws.

Piv txwv corrosion tiv thaiv cov ntaub ntawv

Kev ntsuam xyuas cov teb hauv ib lub roj av ntim cov roj av muaj cov qauv kev ntseeg tom qab 10 xyoo, thaum tooj dag li qub hloov hauv 3 xyoos.

Kev hloov pauv tau zoo hauv cov roj av zoo nkauj

Cov yam ntxwv zoo hloov kho

PEX cov khoom pov thawj:
