Txawm li cas los xij, pvc kav tsis yog li muaj zog raws li cov kav hlau hlau thiab tej zaum yuav dhau los ua cov nkig nyob rau hauv huab cua hauv huab cua sov lossis UV kis.
1.5 CPVC (chlorinated polyvinyl chloride) kav dej
CPVC kav yog zoo ib yam li pvc tab sis tuaj yeem ua kom muaj qhov kub thiab txias.
Lub zog thiab lub zog
Ntau cov cua sov-resistant dua li pvc.
Muaj zog thiab ntau ruaj khov nyob rau hauv cov ntawv thov dej kub.
Tuaj yeem kawg50+ xyoo, tab sis tej zaum yuav ua rau tsis muaj hnub ci ncaj qha.
1.6 HDPE (High-ntom polyethylene) kav dej
Hdpe kav yog dav siv rau cov dej mov, roj faib, thiab cov ntawv thov kev lag luam vim lawv qhov siab hloov kho thiab muaj zog.
Lub zog thiab lub zog
Heev tiv tau rau kev corrosion, tshuaj lom neeg, thiab kev cuam tshuam.
Muaj peev xwm kav 50-100 xyoo.
Saj zawg zog thiab tiv taus kev tawg, tab sis yuav tsis muaj zog nyob rau hauv cov loads huab ua steel lossis hlau.

Lub zog thiab lub zog
Tiv taus khov thiab nthuav dav.
Muaj peev xwm kav 40-50 xyoo.
Txawm li cas los xij, tsis yog muaj zog raws li cov kav hlau hlau thiab tuaj yeem puas los ntawm UV kis.
2. Cov yeeb nkab twg yog qhov muaj zog tshaj?
Zas cov kav hlau yog qhov muaj zog tshaj plaws thiab feem ntau siv tau ntau yam thiab muaj cov khoom muaj zog ntau.
Cov kav hlau steel (cov hlau roj carbon (carbon lossis stainless hlau) kuj muaj zog heev thiab tuaj yeem siv rau hauv cov chaw siab thiab kev muaj kev lag luam.
