Galvanized Hlau Pulley

Galvanized Hlau Pulley nyob hauv ib qho tshwj xeeb hauv kev ua lag luam, txhais tau tias yuav luag tshwj xeeb los ntawm nws cov nqi txiav txim siab kom zoo dua. Qhov no pulley yog tsim los ntawm stamped los yog cam khwb cia hlau, uas yog ces coated nrog ib tug txheej ntawm zinc (galvanized) los muab ib tug yooj yim kev tiv thaiv tiv thaiv rusting tam sim ntawd. Nws lub hauv paus yog vim li cas rau qhov uas twb muaj lawm yog los pab tsim cov khoom lag luam zawv zawg ntawm tus nqi qis tshaj plaws, ua kom yooj yim tshuaj ntsuam kab nkag tau rau ultra- pob nyiaj siv nruj lossis cov xwm txheej pom tau ib ntus.

Txawm li cas los xij, nws yog ib qho tseem ceeb kom nkag siab txog cov kev txwv uas muaj nyob nrog cov nqi qis no. Lub galvanized hlau pulley muaj lub hauv paus ua haujlwm luv dua. Cov zinc txheej yog nyias thiab tuaj yeem hnav tawm los ntawm kev sib txhuam tawm tsam aluminium khiav. Thaum lub hauv paus hlau raug, nws yuav sai sai oxidize thiab xeb. Cov xeb no ua rau cov khoom ntxhib, tsis sib xws uas ua rau lub rub tawm lo, jam, thiab tsim cov suab nrov sib tsoo. Cov xeb residue kuj tuaj yeem stain thiab ua puas rau nws tus kheej. Tsis tas li ntawd, cov hlau tsis zoo li hnav- tiv taus zoo li nylon, ua rau cov neeg kho tshuab degradation sai dua. Thaum pib ua haujlwm, Galvanized Iron Pulley feem ntau sawv cev rau lub sijhawm ntev dua - tus nqi vim qhov xav tau hloov ua ntej ntawm tag nrho lub vijtsam.
