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 kev ua kom 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 cov 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. Xyuas kom raug kho los ntawm cov kuab tshuajNyeem ntxiv…
Kev daws teeb meem ntawm cov hmoov txheej txheej kub dip galvanizing
1. Kev kho tsis tiav: Polyester hmoov txheej hmoov yog cov thermosetting resins uas hla mus rau lawv daim ntawv organic kawg los ntawm kev tuav ntawm qhov kub (feem ntau 180 o C), li 10 feeb. Curing qhov cub yog tsim los muab lub sijhawm no ntawm qhov kub thiab txias ua ke. Nrog cov khoom kub dip galvanized, nrog rau lawv cov ntu hnyav dua, nws yog ib qho tsim nyog los xyuas kom meej tias lub sij hawm stoving txaus tau tso cai kom ua tau raws li cov lus qhia kho. Ua ntej cua sov ntawm kev ua haujlwm hnyav yuav pab ua kom cov txheej txheem kho kom saiNyeem ntxiv…
