pretreatment nruas & cua sov
Khoom Piav Qhia
- Pretriceator yog tus txheej txheem tseem ceeb ntawm kub-dip galvanizing, uas muaj qhov cuam tshuam tseem ceeb ntawm cov khoom lag luam galvanized. Pretrice cua sov muaj xws li: degreast, xeb tshem tawm, ntxuav dej, plating pab, plating txheej txheem, thiab lwm yam.
Tam sim no, nyob rau hauv lub tsev kub-dip galvanizing kev lag luam, cov qhob pob zeb turving tank yog siv dav. Nrog rau cov lus qhia ntawm kev nce qib kub-dip galvanizing tshuab hauv Europe thiab America, PP (Polyethylene) PE (polyethylene) PU (Polyethylene) yuav siv tsis siv neeg kub-dip galvanizing ntau lawm kab.
Ua raws li qhov mob hnyav ntawm cov roj stain ntawm workpiece nto, degreasing yog tshem tawm hauv qee cov txheej txheem.
Cov kev pab txhawb nqa lub tank, dej pab kub li cas thiab plating pab Tank yog feem ntau ntawm cov qauv ua vaj tse, thiab qee cov khoom siv uas yog lub tank tank.
Pretrice cua
Siv cov khib nyiab kub ntawm Flue roj kom tshav kub txhua lub tsheb tso tsheb hlau npaj ua ntej, suav nrog degreasing,picklingThiab ib qho kev plating plating. Cov khib nyiab kub muaj xws li:
1) installation ntawm kev sib txuas ua ke ua pa hluav taws xob hauv flue;
2) Ib pawg ntawm Pfa Tshav Kub Hloov Hloov nyob rau ntawm ob qho kawg ntawm cov pas dej;
3) cov dej muag muag;
4) Tswj system.
Pretricatment cua sov muaj peb ntu:
Flue Roj Kub Hloov Pauv
Raws li tag nrho cov nyiaj los ua kom sov, cov sib xyaw ua ke nrog cov cua sov ua kom muaj zog thiab tsim kom muaj cua sov tuaj yeem ua kom muaj cua sov kom tau raws li cov cua sov yuav tsum tau ua. Yog tias tsuas yog cov pov tseg kub ntawm cov flue tsis tuaj yeem ntsib cov cua sov cua sov xav tau ntawm kev kho cua sov, ib pawg ntawm cov cua kub kub tuaj yeem muab ntxiv rau cov nplaim hluav taws.
Cov Hluav Taws Kub Kub yog ua los ntawm tshav kub-resistant stainless hlau lossis 20 # seamless steel yeeb nkab nrog lub zog tshiab infrared nano-txuag lub zog tiv thaiv kev tiv thaiv. Lub zog kub nqus hluav taws kub yog 140% ntawm cov cua sov nqus los ntawm cov pa hluav taws kub kom sov kub.
② PFA Tshav Kub Kub Pauv
③Lub Cub Qhuav
Thaum cov khoom uas ntub dej sab saum toj intrudes rau hauv da dej zinc, nws yuav ua rau qhov zinc kua kom tawg thiab txaws. Yog li ntawd, tom qab kev pab plating, cov txheej txheem ziab khaub ncaws kuj tseem yuav tau saws rau ntu.
Feem ntau, cov ziab khaub ncaws kom qhuav yuav tsum tsis pub tshaj 100 ° C thiab yuav tsum tsis txhob muab tso rau hauv cov duab ntub dej rau hauv cov duab ntsev ntawm cov plating pab ntawm cov chaw.
