DACROMET HEXAGON BOLTS-Elu Corrosion-Na-eguzogide Ngwọta Mgbakwunye 

N'adịghị ka bolts electro-galvanized ma ọ bụ na-ekpo ọkụ na-ekpo ọkụ, Dacromet hexagon bolts na-eji usoro mkpuchi na-abụghị electrolytic. Nke a na-ewepụ ihe ize ndụ nke embrittlement hydrogen-uru dị oke mkpa maka bolts dị elu nke akara ule 8.8, 10.9, na 12.9. Ihe nkiri Dacromet dị gịrịgịrị, edo edo (nke a na-ahụkarị 4-12 μm) na-enye nkwụsi ike ịgba nnu dị elu, nguzogide okpomọkụ, yana ogologo oge mgbochi nchara, na-eme ka bolts ndị a bụrụ nhọrọ kacha mma na ụgbọ ala, ihe owuwu, ike ikuku, mmiri na ngwa akụrụngwa ụlọ ọrụ.

2. Gịnị bụ mkpuchi Dacromet?

Dacromet bụ inorganic, teknụzụ ọgwụgwọ elu igwe dabere na mmiri nke nwere isi nke ultra-fine zinc flakes, flakes aluminom, na ihe nkedo dabere na chromium. Mgbe etinyere ya na bolt hexagon ma gwọọ ya na okpomọkụ dị elu (ihe dị ka 300 Celsius C), flakes na-adaba n'ọtụtụ n'ígwé na-ekpuchi elu, na-etolite ihe mgbochi ọla ọcha na-acha ntụ ntụ. Nke a multi-layer Ọdịdị na-emepụta ma a anụ ahụ mgbochi megide mmiri na electrolytes na àjà anodic usoro nke na-arụsi ọrụ ike na-eguzogide nchara guzobe.

Ihe mkpuchi dị na bolt hexagon Dacromet na-enye nchebe abụọ: flakes zinc na-arụ ọrụ dị ka anode ịchụàjà, na-emebi emebi nke ọma iji chebe mkpụrụ nchara, ebe flakes aluminom na matrix inorganic na-eme ka ihe mgbochi na-eme ka ọ dịkwuo mma. N'ihi na usoro a abụghị nke electrolytic, ọ dịghị hydrogen a na-ewebata n'ime ígwè lattice, na-echekwa n'ụzọ zuru ezu n'ibu ike bolts.

3. Usoro mkpuchi Dacromet maka Hexagon Bolts

Mmepụta nke bolt hexagon Dacromet a pụrụ ịdabere na ya na-eso usoro ejiri nlezianya chịkwaa iji bulie nrapado, ịdị n'otu, na arụ ọrụ mgbochi corrosion:

1. Nkwadebe elu: A na-enweta ihe mkpuchi ahụ nke ọma na nchacha ma ọ bụ nchacha alkaline. A na-ama ụma na-ezere ịchịkọta acid iji gbochie mmịnye hydrogen nke nwere ike iduga n'ịgbata bolts dị ike.

Ngwa mkpuchi 2. A na-emikpu bolts hexagon ahụ a kpochara, na-efesa ya, ma ọ bụ tinye ya n'ime mmiri Dacromet slurry nwere zinc na flakes aluminum. Dip-spin bụ usoro mmepụta ihe na-emekarị maka nhazi nke bolts.

3.Curing / Sintering: A na-esi nri bolts ndị a na-ekpuchi ya na ihe dịka 300 Celsius. N'oge na-agwọta ihe nkedo reacts na dara flakes sinter n'ime a na-aga n'ihu, tightly adherent inorganic nkiri.

4. Nyocha nke ọma: A na-enyocha bolts hexagon Dacromet emechara maka mkpuchi mkpuchi, nrapanye, ọdịdị na arụmọrụ nnu iji kwe nkwa nchebe mgbochi nchara na-agbanwe agbanwe.

4. Ntụle arụmọrụ nke mkpuchi mgbochi corrosion

Tebụlụ na-esonụ na-achịkọta isi ọdịiche dị n'etiti Dacromet hexagon bolts na bolts ejiri ụzọ mgbochi nchara mechaa:
