Thaum nws los txog rau cov kav dej, xaiv cov khoom tsim nyog rau koj cov kav dej yog qhov tseem ceeb heev. Galvanized steel kav thiab PVC kav yog ob txoj kev xaiv, txhua tus muaj lawv tus kheej zoo thiab qhov tsis zoo. Hauv tsab ntawv blog no, peb yuav tshawb xyuas qhov sib txawv ntawm cov kav dej galvanized thiab PVC kav thiab pab koj
xaiv cov khoom tsim nyog rau koj cov kav dej xav tau.
Galvanized steel kav
Galvanized steel kav yog steel kav uas tau coated nrog ib txheej ntawm zinc los tiv thaiv corrosion thiab xeb. Cov txheej txheem ntawm galvanizing suav nrog dipping cov kav hlau hauv molten zinc, tsim kom muaj kev sib raug zoo ntawm cov hlau thiab zinc txheej. Galvanized steel kav yog muaj zog, ruaj, thiab tiv taus corrosion thiab xeb. Lawv feem ntau siv hauv cov kav dej, HVAC, thiab kev siv dej kho mob.
Qhov zoo ntawm Galvanized Steel Pipes rau Cov kav dej:
Durability: Galvanized steel kav yog qhov ruaj khov, ua rau lawv muaj kev xaiv zoo rau kev siv kav dej.
Corrosion Resistance: Cov zinc txheej ntawm cov kav dej galvanized ua rau lawv tiv taus xeb thiab xeb.
Kub Ua Haujlwm: Galvanized steel kav tuaj yeem tiv taus qhov kub thiab txias, ua rau lawv haum rau kev siv dej kub.
Qhov tsis zoo ntawm Galvanized Steel Pipes rau Cov kav dej:
Nqi: Galvanized steel kav yuav kim dua lwm yam ntaub ntawv.
Kev teeb tsa: Galvanized steel kav yuav tsum muaj kev txawj ua haujlwm rau kev teeb tsa thiab tuaj yeem ua haujlwm nyuaj vim lawv qhov hnyav thiab nruj.
Cov kav dej PVC
Cov kav dej PVC yog tsim los ntawm cov khoom siv yas hu ua polyvinyl chloride. Lawv yog lub teeb yuag, yooj yim rau kev ua haujlwm nrog, thiab tiv taus corrosion thiab xeb. Cov kav dej PVC feem ntau yog siv rau hauv cov kav dej, dej, thiab kev siv dej.
Qhov zoo ntawm cov kav dej PVC rau cov kav dej:
Tus nqi:
Cov kav dej PVC feem ntau pheej yig dua li lwm yam khoom siv.
Lub teeb yuag: PVC kav yog lub teeb yuag thiab yooj yim los tuav, ua rau lawv yooj yim rau nruab.
Chemical Resistance: PVC kav yog resistant rau feem ntau cov tshuaj, ua rau lawv haum rau ntau yam kev siv kav dej.
Disadvantages ntawm PVC yeeb nkab rau kav dej:
Kev Txwv Kub Kub: Cov kav dej PVC muaj qhov txwv kub thiab tsis haum rau kev siv dej kub.
Brittle: PVC cov kav dej tuaj yeem ua nkig dhau sijhawm, ua rau lawv muaj kev cuam tshuam los yog tawg.
