pretreatment nruas & cua sov
Product Description
- Pretreatment yog txheej txheem tseem ceeb ntawm kub-dip galvanizing, uas muaj feem cuam tshuam rau qhov zoo ntawm cov khoom galvanized. Pretreatment cua sov muaj xws li: degreasing, xeb tshem tawm, ntxuav dej, plating pab, ziab txheej txheem, thiab lwm yam.
Tam sim no, nyob rau hauv domestic kub-dip galvanizing kev lag luam, cov pob zeb granite pickling tank yog dav siv. Nrog rau kev qhia txog kev siv tshuab kub-dip galvanizing siab heev hauv Tebchaws Europe thiab Amelikas, PP (polypropylene) / PE (polyethylene) pickling tso tsheb hlau luam tau nce siv hauv qee qhov tsis siv neeg kub-dip galvanizing ntau lawm kab.
Nyob ntawm qhov hnyav ntawm cov roj stain ntawm lub workpiece nto, degreasing raug tshem tawm hauv qee cov txheej txheem.
Lub tank degreasing, dej ntxuav tank thiab plating aid tank feem ntau yog cov qauv ua vaj tse, thiab qee qhov yog ua los ntawm cov khoom siv tib yam li lub tank pickling.
Pretreatment cua sov
Siv cov khoom siv hluav taws xob pov tseg ntawm cov roj hluav taws xob kom sov txhua lub tank ua ntej kev kho mob, suav nrog degreasing,picklingthiab pab plating. Cov khib nyiab cua sov system muaj xws li:
1) Kev teeb tsa ntawm cov khoom siv hluav taws xob sib xyaw ua ke hauv flue;
2) Ib txheej ntawm PFA kub exchanger yog ntsia ntawm ob qho kawg ntawm txhua lub pas dej;
3) Mos dej system;
4) Tswj system.
Pretreatment cua sov muaj peb ntu:
① Flue gas heat exchanger
Raws li tag nrho cov cua sov uas yuav tsum tau rhuab, qhov sib xyaw flue heat exchanger yog tsim thiab tsim, kom cov cua sov tuaj yeem ua tau raws li qhov xav tau cua sov. Yog tias tsuas yog cov hluav taws kub ntawm lub flue tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov cua kub cua sov ntawm kev kho ua ntej, ib txheej ntawm cov cua kub cua sov tuaj yeem muab ntxiv los xyuas kom meej cov roj flue ntim.
Lub tshav kub exchanger yog ua los ntawm cov cua kub-resistant stainless hlau los yog 20 # seamless steel yeeb nkab nrog ib tug tshiab infrared nano high-temperature zog-txuag anti-corrosion txheej. Lub zog nqus hluav taws xob yog 140% ntawm cov cua sov nqus los ntawm cov khoom siv hluav taws xob zoo tib yam.
② PFA kub exchanger
③Qhuav qhov cub
Thaum cov khoom uas ntub dej nkag mus rau hauv zinc da dej, nws yuav ua rau cov kua zinc tawg thiab txaws. Yog li ntawd, tom qab kev pab plating, cov txheej txheem ziab yuav tsum tau saws rau qhov chaw.
Feem ntau, qhov ziab kom qhuav yuav tsum tsis pub tshaj 100 ° C thiab yuav tsum tsis txhob qis dua 80 ° C. Txwv tsis pub, cov khoom tuaj yeem tsuas yog muab tso rau hauv qhov chaw ziab kom ntev, uas yuav yooj yim ua rau cov dej nqus ntawm zinc chloride hauv cov ntsev. zaj duab xis ntawm cov plating pab rau saum npoo ntawm qhov chaw.
