Cov kav dej ntawmCOMPACT POB VALVEyog ib hom khoom siv hauv tsev, uas tau hlub los ntawm ntau tus neeg siv khoom rau lawv cov yam ntxwv zoo thiab kev ua haujlwm siab.Yog li no, hnub no, peb yuav pib nrog kev faib cov kav dej yas, thiab qhia txhua tus paub txog cov kav dej yas.
Nyob rau theem no, muaj cov nram qab no 6 hom ntawm cov kav dej yas feem ntau siv hauv kev muag khoom:
1. Rigid polyvinyl chloride yas yeeb nkab, alias UPVC yeeb nkab.Nws yog lub teeb hauv qhov hnyav, tsis tshua muaj zog, muaj qhov ua tau zoo ntawm tus kheej tua hluav taws thiab kev ruaj ntseg tshuaj zoo, thiab tuaj yeem siv rau cov dej ntws, dej phwj tuaj, qhov cua, thiab lwm yam.
2. Polyethylene yeeb nkab, alias PE yeeb nkab.Raws li qib ntawm qhov ntom ntom, nws tuaj yeem muab faib ua ntau ntom ntom polyethylene yeeb nkab, nruab nrab ntom polyethylene yeeb nkab thiab qis ntom polyethylene yeeb nkab.High-density ones muaj lub zog siab thiab cov cua kub zoo, thiab tuaj yeem siv rau hauv nroog cov pa roj thiab cov kav dej;medium-density sawv daws yuav muaj zog ib txwm nruj thiab lub zog, tab sis muaj zoo elasticity thiab creep kuj;Tsawg-qhov ntom tau yooj yim, elongation tus nqi ntev tau muaj qee qhov kev ua tau zoo, thiab nws tuaj yeem siv rau cov dej khov, hluav taws xob, kev sib txuas lus cable, thiab lwm yam.
3. Cross-linked polyethylene yeeb nkab, alias PE-X yeeb nkab.Nws muaj lub cim xeeb zoo, kev tiv thaiv ib puag ncig, tshuaj lom neeg, tiv thaiv corrosion, kub tsis kam, thiab tuaj yeem siv rau cov khoom siv cua txias thiab cua sov hauv cov tsev, xws li cov kav dej cua sov, cov kav dej hauv nruab nrab, cov kav dej kub, thiab lwm yam. Nws kuj tseem siv tau los ua cov kav dej thauj mus los rau cov zaub mov hauv kev lag luam zaub mov.
4. Random copolymer polypropylene yeeb nkab, alias PP-R yeeb nkab.Nws yog non-toxic, odorless thiab huv si heev.Nrog cov khoom siv hluav taws xob zoo thiab cov khoom ua kom tsis muaj zog, nws yog cov khoom siv dej kub thiab dej txias zoo tagnrho.Nws yog tsuas yog siv rau cov khoom siv dej txias thiab kub kub, dej haus thiab kev thauj mus los, cov cua kub cua sov, thiab cov cua txias hauv cov tsev thiab cov tsev.
5. Polybutene raj, alias PB raj.Nws muaj lub zog siab, zoo creep kuj, thiab yooj yim rau nruab thiab yooj yim rau kev khiav lag luam.Nyob rau tib lub sijhawm, nws tus nqi siab, txoj kab uas hla ntawm cov yeeb nkab yog me me, thiab nws tau yooj yim eroded los ntawm qee cov ntxhiab hydrocarbons thiab cov kuab tshuaj chlorinated, yog li muaj qee qhov kev txwv hauv daim ntawv thov.
6. Acrylonitrile-butadiene-styrene yeeb nkab, alias ABS yeeb nkab.Nws muaj cov cua sov ua haujlwm siab, tiv thaiv corrosion, nkag mus, thiab tsis muaj tshuaj lom, tsis muaj ntxhiab, huv thiab huv, tab sis muaj cov yam ntxwv tsis zoo ntawm cov cua sov hloov mus rau qhov chaw raug tshav ntuj.Txawv teb chaws, nws yog feem ntau yog siv rau cov dej phwj tuaj, irrigation, thiab underground conduction;nyob rau hauv Suav teb, nws yog feem ntau yog siv rau sab hauv tsev dej mov, tsheb thauj mus los ntawm corrosive tshuaj, thiab lwm yam.
