Kub plating hlaunyob rau hauv cov txheej txheem tsim, vim tias qhov cuam tshuam ntawm ib puag ncig, yuav ua rau cov tsos ntawm galvanized dub, thaum lub sij hawm muaj qee yam cuam tshuam xws li huab cua tsis zoo, impurities hauv cov txheej txheem tsim, tes hws thiab lubricating roj, yuav ua rau cov tsos ntawm galvanized dub. .Qee qhov kev daws teeb meem yooj yim tuaj yeem zam tsis txhob kub plating hlau nyob rau hauv cov txheej txheem tsim, blackening los yog ncua lub sij hawm discoloration, xws li cov chaw ua hauj lwm raws li boring, txiav thiab tsis xav tau cov tshuaj, tus neeg teb xov tooj nrog huv si hnab looj tes, thiab lwm yam.
Zinc passivation kev kho mob yuav tsum tau ua tom qab zinc immersion.Zinc passivation kev kho mob muaj txiaj ntsig zoo los tiv thaiv kev puas tsuaj, uas tuaj yeem siv los txuas ntxiv lub sijhawm ntawm kev hloov xim.Qhov ob tuaj yeem siv tau los ntawm kev siv cov discoloration.Qhov zoo ntawm annealing hlau:dub kabmuaj elasticity zoo heev thiab yooj, tuaj yeem tswj nws qib ntawm softness thiab hardness nyob rau hauv cov txheej txheem annealing, ua los ntawm cov hlau zoo, feem ntau yog siv rau kev khi hlau thiab khi hlau hauv kev tsim kho kev lag luam.
Tus xov tooj tseem ceeb yog 5 #-38 #, uas yog softer thiab hloov tau ntau dua li cov hlau dub zoo tib yam.Lub softness yog uniform thiab xim zoo ib yam.Annealing hlau kuj yog siv dav, hlau mesh weaving tom qab plating, plating thiab lwm txoj kev, tom qab kev kho mob ntawm cov hlau los yog hlau mesh muaj corrosion kuj zoo, oxidation kuj yam ntxwv, yog li siv nyob rau hauv lwm yam yuav zoo dua ua si lub luag hauj lwm ntawm annealing hlau.
