1. Cov khoom lag luam Raw yog dab tsi?
Xaiv Xaiv Sau
Cov ntaub ntawv nquag: Carbon Hlau xws li Q235, Q345, 45 # STEEL, lossis cov hlau tsawg (xws li 20cr) {}}
Cov kev qhia tshwj xeeb: Round bar txoj kab txoj kab feem ntau yog 5 ~ 200mm, txiav kom teev qhov ntev raws li kev txiav txim.
Nto Pretreatment
Degreasing: Use alkali solution (such as sodium hydroxide) or organic solvent to remove surface oil stains to avoid affecting the adhesion of the zinc layer.
Rust tshem tawm: Tshem tawm cov nplai oxide los ntawm pickling (hydrochloric acid los ntawm cov roj acid lossis sulfuric acid daws) kom ua rau cov hlau substrate .
2. Dab tsi yog cov txheej txheem tseem ceeb ntawm kub-dip galvanizing?
Plating kho
Tom qab pickling, reating nyob rau hauv lub plating daws kev daws teeb meem + ammonium chloride) los tiv thaiv cov tshuaj oxidide ntsev thiab txhawb nqa zinc cov kua rau infiltration {}}
Kub dip galvanizing
Zinc Lauj Cua Sov: Qhov Kub Kub Kub no yog tswj hwm ntawm 430 ~ 460 {{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{}
Tshav kub diffusion thiab txias
Nqa thiab ntsuas kub: Tom qab rod rod yog tsa tawm ntawm cov kua zinc uas tau tawg ntawm cov txheej huab cua (cov txheej kub siab) los tswj cov txheej zinc (cov txheej siab ntawm zinc txheej {}}
Txias: Ntuj cua txias lossis dej txias, yog li cov txheej yas-zinc alloy txheej (zn fe txheej .
3. Cov dab tsi tom qab ua xws li?
Nto Kho
Passivation: kev cuam tshuam hauv kev daws teeb meem chromate (xws li kev ua haujlwm passivation (chromium-free passivation tuaj yeem siv rau ib puag ncig cov txheej txheem phooj ywg zoo).
Oiling: Txau tawm tsam roj xeb, tsim nyog rau kev khaws cia hauv thaj chaw noo noo.
Kev Soj Ntsuam Zoo
Zinc Txheej Thickness: pom nrog cov xim thoj sib nqus ntawm .
Cov tsos tshuaj xyuas: visually tshem zinc nodules, ploj plating, nto nrws thiab lwm yam tsis xws luag .
Daim Ntawv Qhia Tawm: khoov test los yog rab las kuaj kom ntseeg tau tias cov txheej zinc tsis poob tawm .
{{0 {}} Dab tsi yog qhov tseem ceeb tswj cov ntsiab lus ntawm cov txheej txheem?
Pengling concentration: hydrochloric acid confentration 15% ~ 20%, ntsuas kub, zam dhau kev tsis tuaj yeem thiab substrate ploj .
Zinc Lu Impurities: Tsis tu ncua Xinc Slag, Tswj Cov Hlau Cov Ntsiab Lus<0.03% to prevent the zinc layer from becoming brittle.
Cua txias tus nqi: Txoj kab uas hla loj dua yuav tsum tau txias los ntawm kev sib tw kub, kom tsis txhob muaj kev ntxhov siab los ntawm qhov sib txawv ntawm sab hauv thiab sab nraud .
5. Dab tsi yog qhov tshwm sim nquag thiab cov kev daws teeb meem?
Kev tsis sib xws zinc txheej: kho cov pas nrig Lifting ceev thiab ntsuas hniav rab riam
Missed Plating: ntxiv dag zog rau kev xaiv thiab hloov cov plating daws
TAS TAS Zinc Txheej: Luv Dicken lub sijhawm siv zinc thiab nce zinc adass kub
