Tshaj tawm rau 22-06-2016 Zinc flake txheej yog ib hom tshiab ntawm corrosion kuj txheej, nws tau siv dav, zinc flake txheej txheej txheem feem ntau yog cov khoom siv hauv paus, degreasing, derusting, txheej, preheating, curing, txias.
1. Degreasing: workpiece nto yuav tsum degreased, feem ntau muaj peb txoj kev: organic solvent degreasing, dej-raws li degreasing tus neeg saib xyuas, kub carbonization degreasing.Txawm hais tias degreasing kom huv si, yuav ncaj qha cuam tshuam lub adhesion ntawm txheej.
2. Derusting thiab deburring: lub workpiece nrog xeb los yog burr yog nruj me ntsis txwv tsis pub ncaj txheej txheej, yuav tsum dhau lub derusting thiab deburring txheej txheem, cov txheej txheem no tau zoo siv txhua yam txoj kev, tsis txhob acid los tiv thaiv hydrogen embrittlement.
3. Txheej: workpiece tom qab degreasing thiab derusting yuav tsum dipping, txau los yog txhuam asap.
4. Ua ntej cua sov: workpiece nrog zinc flake txheej xim rau ntawm qhov chaw yuav tsum ua ntej cua sov 10-15 feeb asap nyob rau hauv qhov kub ntawm 120 + 20 ℃, ua rau cov txheej txheej kua dej evaporation.
5. Curing: workpieces tom qab cua sov ua ntej yuav tsum kho nyob rau hauv 300 ℃ siab kub, kho lub sij hawm 20-40 feeb, kuj yuav tsim nyog tsa qhov kub thiab txias kom shorten curing lub sij hawm.
6. Ua kom txias: Cov khoom ua haujlwm tom qab kho yuav tsum tau ua kom txias tag nrho los ntawm kev ua kom txias rau kev rov ua dua lossis ua tiav cov khoom kuaj xyuas.
