HDPE (High-Density Polyethylene) cov kav dej tuaj yeem koom nrog siv ntau txoj hauv kev nyob ntawm daim ntawv thov thiab qhov yuav tsum tau ua. Nov yog peb txoj hauv kev los koom nrog HDPE kav:
1.Npaj Fusion
Butt fusion yog txoj kev siv ntau tshaj plaws los koom nrog HDPE kav. Nws suav nrog cua sov qhov kawg ntawm cov kav dej mus rau lawv qhov chaw melting siv lub tshuab taub qab fusion. Thaum qhov kawg yog molten, lawv raug nias ua ke thiab tuav hauv siab kom txog thaum cov khoom txias thiab tsim cov khoom sib koom ua ke. Txoj kev no muab kev sib txuas ruaj khov thiab tsis muaj pov thawj.
2. Hluav taws xob
Electrofusion yog lwm txoj kev nrov rau kev koom nrog HDPE kav. Nws suav nrog kev siv tshwj xeeb fittings nrog embedded cua sov ntsiab. Cov fittings tau muab tso rau ntawm qhov kawg ntawm cov kav dej, thiab cov khoom siv hluav taws xob tau dhau los ntawm cov khoom cua sov, yaj cov khoom siv HDPE thiab tsim kom muaj kev sib txuas ntawm cov yeeb nkab thiab cov khoom siv. Electrofusion pob qij txha yog txhim khu kev qha thiab feem ntau siv nyob rau hauv cov pa roj faib systems.
Mechanical Couplings
Mechanical couplings los yog compression fittings yog siv rau me me txoj kab uas hla HDPE kav los yog nyob rau hauv daim ntawv thov uas yuav tsum tau disassembly. Cov couplings no muaj ob ntu: cov txiv ntoo compression thiab ib lub nplhaib sib cais. Lub nplhaib sib cais yog muab tso rau ib ncig ntawm cov yeeb nkab, thiab cov txiv ntoo compression yog nruj, compressing lub nplhaib sib cais tawm tsam cov yeeb nkab thiab tsim kom muaj kev ruaj ntseg sib koom ua ke.
Nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov chaw tsim khoom cov lus qhia thiab cov qauv kev lag luam thaum koom nrog cov kav dej HDPE kom ntseeg tau tias kev txhim kho kom zoo thiab kev sib raug zoo.
