Nrog rau kev loj hlob sai ntawm kev npaj hauv nroog thiab kev tsim kho,PE tubtam sim no tau siv dav hauv ntau yam kev tsim kho, thiab qhov zoo tau lees paub los ntawm peb.Yuav kom siv tau zoo dua, cia peb kawm txog cov txheej txheem ntawm PE yeeb nkab electrofusion vuam.Muaj ntau txoj hauv kev vuam rau PE kav, ntawm cov khoom siv hluav taws xob fusion vuam yog qhov ntau heev.
Peb siv lub tshuab hluav taws xob fusion vuam tshuab los ua kom muaj zog thiab ua kom sov cov hlau tsis kam kos rau hauv phab ntsa sab hauv ntawm cov yeeb nkab electrofusion, thiab siv lub zog cua sov los txuas rau PE yeeb nkab nrog cov yeeb nkab.Feem ntau, thaum cov yaj nyob rau hauv qhov kub thiab txias siab, cov saw hlau molecular ntawm PE yeeb nkab yaj yuav diffuse nrog ib leeg nyob rau hauv lub molten ib feem ntawm lub interface tom qab qhov khoob ntawm ob kawg ntawm cov yeeb nkab raug kaw.
Thaum qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv mus txog qhov loj me uas txiav txim siab los ntawm cov saw txuas, lub interface tom qab ntuj txias yuav tsum muaj qee qhov vuam lub zog los tsim cov yeeb nkab txuas txuas.Kev sib txuas ntawm PE rau cov raj xa dej feem ntau yog nyob ntawm qhov tsim ntawm cov hluav taws xob fusion yeeb nkab qhov chaw thiab qhov kub ntawm qhov tsis kam.
Cov yam ntxwv tsis kam, kev ruaj ntseg ntawm cov khoom siv hluav taws xob yog muab los ntawm electrofusion vuam, kev ua haujlwm ntawm cov khoom siv raj thiab cov khoom siv raj.Yog li ntawd, thaum peb welding PE kav, peb yuav tsum kub-kho cov PE kav ua ntej.Qhov no tuaj yeem tsis tsuas yog txhim kho lub zog ntawm cov kav dej, tab sis kuj ua tiav cov txiaj ntsig zoo.
