Kedu ihe bụ ọgwụgwọ mbụ maka mkpuchi agụụ?

Ọrụ pretreatment nke mkpuchi mkpuchi na-agụnye usoro ndị a, nke ọ bụla n'ime ha na-ewere ọrụ dị iche iche iji hụ na àgwà na mmetụta nke usoro mkpuchi:

Mba.1 Usoro ọgwụgwọ tupu ọgwụgwọ

1. Egweri elu na polishing

Jiri abrasives na ihe na-egbuke egbuke mee ihe na-arụ ọrụ nke ọma n'elu akụkụ ndị a kpụrụ akpụ iji wepụ microstructure siri ike nke elu ma nweta ọkwa ụfọdụ.

Ọrụ: Meziwanye nkwekọ na ịdị n'otu nke mkpuchi ahụ, mee ka elu nke mkpuchi ahụ dịkwuo mma ma mara mma.

2.Degreasing

Nabata mgbaze mgbaze, chemical ma ọ bụ electrochemical ụzọ wepụ griiz na mmanụ n'elu plated akụkụ.

Ọrụ: Gbochie mmanụ na griiz ka ọ ghara ịmịpụta afụ, flaking na ntụpọ ndị ọzọ na usoro mkpuchi, ma melite nchikota nke mkpuchi.

3.Nhicha

Jiri acid, alkali, ihe mgbaze na ihe ngwọta kemịkal ndị ọzọ imikpu ma ọ bụ ultrasonic, plasma ihicha akụkụ plated iji wepụ oxides elu, nchara na adịghị ọcha ndị ọzọ.

Ọrụ: iji mee ka ọ dịkwuo ọcha n'elu akụkụ ndị a na-ekpuchi, iji hụ na ihe mkpuchi na ihe dị n'etiti njikọ dị nso.

4.Ativation ọgwụgwọ

Mebie elu nke akụkụ plated na acid na-adịghị ike ma ọ bụ ngwọta pụrụ iche iji wepụ oyi akwa passivation n'elu ma melite ọrụ nke elu.

Ọrụ: iji kwalite mmeghachi omume kemịkalụ ma ọ bụ ngwakọta anụ ahụ n'etiti ihe mkpuchi na elu plated, iji meziwanye nchikota na ịdịte aka nke mkpuchi.

Nke 2 ọrụ nke pretreatment

1. Meziwanye mma mkpuchi

Ngwọta mbụ nwere ike hụ na elu nke akụkụ ndị a na-ekpuchi efere dị ọcha, dị nro na nke na-adịghị ọcha, nke na-eme ka a na-edozi otu nke ihe mkpuchi na nchikota nso.

Nke a na-enyere aka melite adhesion mkpuchi, ịdị n'otu na ike siri ike na ihe ngosi arụmọrụ ndị ọzọ.

2. Kwalite usoro mkpuchi

Enwere ike imezi usoro nhazi ahụ dị ka ihe dị n'ime ihe ndị a na-emepụta ihe na ihe mkpuchi chọrọ iji gbanwee usoro mkpuchi na ngwá ọrụ dị iche iche.

Nke a na-enyere aka ịkwalite usoro usoro mkpuchi ma melite arụpụta ọrụ na mkpuchi mkpuchi.

3. Belata ntụpọ mkpuchi

Ngwọta ọgwụgwọ nwere ike wepụ oxides, anụ ahụ na-adịghị mma, burrs na ihe ndị ọzọ dị n'elu akụkụ ndị a na-ekpuchi, na-egbochi ihe ndị a ka ọ bụrụ isi iyi nke ntụpọ n'oge usoro mkpuchi.

Nke a na-enyere aka ibelata afụ, flaking, cracks na ntụpọ ndị ọzọ na usoro mkpuchi, ma melite mma na ojiji nke mkpuchi.

4. Gbaa mbọ hụ na nchekwa mmepụta

Nzọụkwụ nke mkpocha mmanụ na ihicha kemịkalụ n'ime usoro ọgwụgwọ mbụ nwere ike wepụ ihe ndị na-ere ọkụ na ihe mgbawa na ihe ndị na-egbu egbu na ndị na-emerụ ahụ n'elu akụkụ nke plated.

Nke a na-enyere aka belata ihe ize ndụ nke ọkụ, mgbawa ma ọ bụ mmetọ gburugburu ebe obibi na ihe mberede nchekwa ndị ọzọ na usoro mkpuchi.

Na nchịkọta, ọrụ pretreatment nke oghere mkpuchi na-agụnye ichikota elu na polishing, mmanu mmanu, ihicha kemịkal na ịgbalite usoro ọgwụgwọ. Nke ọ bụla n'ime usoro ndị a na-ewere ọrụ dị iche iche iji hụ na ịdị mma na ịdị irè nke usoro mkpuchi. Site na pretreatment, mkpuchi mma nwere ike imeziwanye, usoro mkpuchi nwere ike ime ka ọ dịkwuo mma, enwere ike ibelata ntụpọ mkpuchi na nchekwa mmepụta ihe.
