Galvanized steel nruas khoom thiab txheej txheem txheej txheem

Galvanized steel nruas khoom: Zinc yog yooj yim soluble nyob rau hauv acid thiab alkali, yog li nws yog hu ua amphoteric hlau. Galvanized steel nruas tsis tshua hloov hauv huab cua qhuav. Nyob rau hauv cov huab cua ntub, ib tug tuab yooj yim zinc carbonate zaj duab xis yuav tsim nyob rau saum npoo ntawm galvanized steel nruas. Nyob rau hauv cov huab cua uas muaj sulfur dioxide, hydrogen sulfide thiab marine, corrosion kuj tsis zoo, tshwj xeeb tshaj yog nyob rau hauv cov huab cua uas muaj organic acid nyob rau hauv kub thiab high humidity, zinc txheej ntawm galvanized steel nruas yog yooj yim corroded. Tom qab zinc txheej ntawm galvanized steel nruas yog passivated, dyed los yog coated nrog lub teeb tiv thaiv, nws cov kev tiv thaiv thiab cov khoom zoo nkauj tuaj yeem txhim kho tau zoo. Cov khoom no tsis tshua muaj siv rau hauv cov kaus poom tinplate! Tsis txhob hais txog 1L steel nruas thiab 5L steel nruas! Txawm li cas los xij, 18L galvanized steel nruas yog ib qho tshwj xeeb, vim tias lawv hnyav dua thiab tsis tuaj yeem siv li 20L steel nruas. Lubricating roj ntim steel nruas. Cov txheej txheem txheej txheem ntawm galvanizing: nyob rau hauv ib lub thoob nrog plating pieces, iav pob, zinc hmoov, dej thiab ib tug rotating nruas, lub iav pob raws li ib tug cuam tshuam nruab nrab rotates nrog lub nruas, rubbing rau saum npoo ntawm daim plating thiab hammering los tsim mechanical. thiab lub zog lub cev, nyob rau hauv qhov kev txiav txim ntawm cov neeg ua hauj lwm tshuaj, cov plated zinc hmoov yog "txias-welded" rau saum npoo ntawm plated ib feem los ua ib tug du, uniform thiab meticulous txheej nrog ib tug tuab.
