Yuav tsum tau rau hmoov txheej tshaj kub dip galvanizing

Cov lus qhia hauv qab no tau pom zoo:

• Siv zinc phosphate pretreatment yog tias xav tau qhov adhesion siab tshaj plaws. Nto yuav tsum huv si zoo kawg nkaus. Zinc phosphate tsis muaj tshuaj ntxuav tes thiab yuav tsis tshem cov roj lossis av.
• Siv hlau phosphate yog tias xav tau kev ua tau zoo. Hlau phosphate muaj ib qho tshuaj ntxuav me ntsis thiab yuav tshem tawm cov kab mob me me. Qhov zoo tshaj plaws siv rau pre-galvanized khoom.
• Pre-heat ua hauj lwm ua ntej daim ntawv thov hmoov.
• Siv 'degassing' qib polyester hmoov txheej nkaus xwb.
• Tshawb xyuas qhov kho kom raug los ntawm kev ntsuas hnyav.
• Kho cov cua sov ua ntej thiab kab nrawm kom ntseeg tau tias muaj kev kho mob tag nrho.
• Kub dip galvanize thiab tsis txhob dej los yog chromate quench.
• Tshem tawm tag nrho cov dej ntws tawm thiab qhov tsis xws luag.
• Powdercoat hauv 12 teev tom qab galvanizing. Tsis txhob ntub qhov chaw. Tsis txhob tawm sab nraud
• Khaws qhov chaw kom huv si. Tsis txhob thauj cov khoom uas tsis tau npog. Diesel fumes yuav paug nto
• Yog hais tias qhov chaw paug tau tshwm sim los yog xav tias, huv si saum npoo nrog proprietary solvent / detergent tsim los ntxuav ua ntej ua hmoov txheej.
