Zinc dabeere Micro mkpuchi metal mgbochi corrosion mkpuchi mmiri mmiri usoro

Ebisara na 2018-09-17Usoro mkpuchi Dacromet: a na-emepụta ihe eji eme ihe n'ime ihe mkpuchi mmiri na-agbaze, wee kpuchie ya n'elu ihe a na-arụ ọrụ nke a na-emebu, buru ya ụzọ na sintered iji mepụta oyi akwa ihe nkiri inorganic.Usoro bụ isi bụ dị ka ndị a: workpiece degreasing → derusting (na-agbawa) → itinye mkpuchi (ma ọ bụ spraying) → ihicha → tupu mmiri → sintering → jụrụ → nnyocha → nkwakọ.

1. Degreasing: Degreasing organic mgbaze ma ọ bụ alkaline ngwọta deoiling.Site n'echiche nke nchebe gburugburu ebe obibi, ekwesịrị iji alkaline degenreasing mee ihe.Mgbe arụrụ arụrụ arụrụ arụ, a chọrọ ka mmiri wee wepụta elu ya.

A na-etinye workpiece n'ime akpa mechiri emechi, a na-ebutekwa onye na-ehicha ihe na nnukwu nrụgide ma fesa ya maka nhicha.Ebe ọ bụ na elu nke workpiece bụ ịnweta mgbochi nchara mmanụ, a compound surfactant nwere emulsified dispersion na ezi dissolving ike họrọ.

2. Mgbawa agbawa: Iji zere ndakpọ hydrogen na mmetọ gburugburu ebe obibi, a naghị eji nchara eme ihe, mana a na-eji agba agba agba.Igwe nchara nchara a na-eji na igwe ogbugba ogbunigwe nwere dayameta sitere na 0.1 ruo 0.6 mm, ikuku gbakọtara na-agbakwa ya.A na-anakọta uzuzu a kpochapụrụ site na onye na-anakọta uzuzu pụrụ iche ma tinye uche.Mwepu na nkwụsịtụ ga-abụ nke ọma, ma ọ bụghị ya, adhesion na corrosion resistance nke mkpuchi ga-ebelata.

3. Mkpuchi mkpuchi: A na-emikpu ihe eji eme ihe na-arụ ọrụ n'ime ihe ngwọta nke Dacromet emepụtara nke ọma.A na-etinyekarị ihe mkpuchi ahụ maka nkeji 2 ruo 3 n'okpuru ntakịrị ịma jijiji wee kpọọ nkụ.Ọ bụrụ na workpiece buru ibu, fesaa ya.Mgbe mkpuchi mkpuchi ma ọ bụ ịgbasa, ma ọ bụrụ na enweghị isi ma ọ bụ mkpuchi mkpuchi mgbe nyochachara, enwere ike itinye ya na mkpuchi ahịhịa.

4. Tupu ịsa achịcha, ịgwọ ọrịa: A na-etinye workpiece mkpuchi mkpuchi na eriri igwe anaghị agba nchara, a naghị ekwe ka arụ ọrụ ahụ na-arapara n'ahụ ibe ya, banye n'ọkụ na-ekpo ọkụ maka nkeji 10-30, wee gwọọ 15 ruo 30 nkeji.The tupu mmiri, ọgwụgwọ okpomọkụ na oge na-tumadi kpebisiri ike site ọkpụrụkpụ nke mkpuchi na size nke workpiece na dị iche iche mkpuchi mmiri mmiri.A na-achịkwa ọsọ mbufe nke eriri igwe anaghị agba nchara nchara.

5. Ọgwụgwọ mgbe emechara: Ọ bụrụ na elu nke ihe nkedo ahụ siri ike mgbe a gwọchara ya, a pụrụ iji ahịhịa siri ike hichaa elu nke ihe nkedo.
