The ọzịza gị n'ụlọnga gbasaa workpiece nweta n'elu micro-corrosion, mgbe nro ihe n'onwe ya, na-ahapụ na-ezighị ezi nchegbu kpatara injection ịkpụzi ma ọ bụ ihe onwunwe, nke mere na ụdi roughening usoro nwere ike ịbụ uniformly na mma corroded.
Usoro nke ịlele nrụgide dị n'ime nke ihe electroplating ga-adị iche maka ihe dị iche iche.Maka ABS, a na-ejikarị usoro ntinye mmiri glacial acetic acid.
③Na-akpachapụ anya
1. Oke njikwa okpomọkụ: 63 ~ 69 ℃
2. ABS plastic bụ terpolymer nke acrylonitrile (A), butadiene (B) na styrene (S).N'oge usoro nhazi ahụ, a na-etinye ihe ndị ahụ plastik ka ọ na-emepụta olulu, na-eme ka hydrophobic dị elu na hydrophilic, nke mere na oyi akwa na-adabere na akụkụ plastik ma jikọta ya nke ọma.
Mkpachapụ anya:
1) Akwa chromium ngwọta nwere ngwa ngwa agbaze na coarsening ọsọ na mma mkpuchi adhesion;ma mgbe uru nke chromic acid na sulfuric acid karịrị 800 g / L, ngwọta ahụ ga-eme ka ọ dị elu, ya mere ọ dị mkpa iji nọgide na-akpali gas.
2) Mgbe itinye uche na-ezughị ezu, mmetụta na-akụda mmụọ adịghị mma;mgbe ntinye uche dị oke elu, ọ dị mfe ịmebiga ihe ókè, mebie ihe, ma weta nnukwu mfu na ịbawanye ọnụ ahịa.
3) Mgbe okpomọkụ ezughị ezu, mmetụta na-adịghị mma adịghị mma, na mgbe okpomọkụ dị elu, ihe ahụ na-adịkarị mfe nrụrụ.
④ Neutralization (isi akụrụngwa bụ hydrochloric acid)
1. Ọrụ: Hichaa chromium hexavalent fọdụrụ na micropores nke ihe ahụ mgbe ọ gbasasịrị na corrosion iji gbochie mmetọ na usoro na-esote.
2. Usoro nke ime ihe: N'oge roughening usoro, ihe roba ahụ na-etisasịwo pụọ, na-akpụ olulu, a ga-enwe roughening mmiri mmiri fọdụrụ n'ime.N'ihi na ion chromium hexavalent dị na mmiri na-eme ihe na-eme ka ọ dị ike nwere ihe ndị na-eme ka ọ dị ike, ọ ga-emerụ usoro na-esote.Hydrochloric acid nwere ike ibelata ya ka ọ bụrụ ion chromium trivalent, si otú ahụ na-efunahụ ihe ndị na-emepụta ihe.
3. Ihe ndị chọrọ nlebara anya:
1) Hydrochloric acid dị mfe ịgbagha, ịkpali gas nwere ike ịkwalite nkwụsịtụ na nhichapụ mmetụta, ma ikuku ikuku adịghị mfe ka ọ buru ibu, ka ịzenarị nkwụsị nke hydrochloric acid volatilization.
2) Mgbe ntinye uche ezughị oke, mmetụta nhicha adịghị mma;mgbe ịta ahụhụ dị oke elu, ọnwụ na-ebu na-ebuwanye ibu na ọnụ ahịa na-abawanye.
3) Mmụba okpomọkụ nwere ike ịkwalite mmetụta ihicha.Mgbe okpomọkụ dị oke elu, mfu volatilization ga-adị ukwuu, nke ga-eme ka ọnụ ahịa dịkwuo elu ma metọọ ikuku.
4) N'oge eji, trivalent ion chromium ga-agbakọ ma na-abawanye.Mgbe mmiri mmiri ahụ bụ akwụkwọ ndụ akwụkwọ ndụ gbara ọchịchịrị, ọ pụtara na enwere ọtụtụ ion chromium trivalent na a ga-edochi ya mgbe niile.
⑤ Mgbalite (catalysis)
1. Ọrụ: Debe oyi akwa nke colloidal palladium na ọrụ catalytic n'elu ihe.
2. Usoro nke ime ihe: polymers nwere ndị na-arụ ọrụ dị iche iche nwere ike ịmepụta ogige na ion metal dị oké ọnụ ahịa.
3. Akpachara anya:
1) Akwụsịla mmiri mmiri na-arụ ọrụ, ma ọ bụghị ya, ọ ga-eme ka onye na-eme ihe na-agbaze.
2) Mmụba nke okpomọkụ nwere ike ime ka mmetụta nke palladium imi.Mgbe okpomọkụ dị oke elu, onye na-eme ihe ga-emebi.
3) Mgbe itinye uche nke onye na-eme ihe na-ezughị ezu, mmetụta mmiri ozuzo nke palladium ezughị ezu;mgbe ntinye uche dị oke elu, mfu na-ebupụta dị ukwuu na ọnụ ahịa na-abawanye.
⑥ Chemical nickel
1. Ọnọdụ njikwa okpomọkụ: 25 ~ 40 ℃
2. Ọrụ: Tinye akwa akwa akwa akwa akwa n'elu ihe ahụ, nke mere na ihe ahụ gbanwere site na onye na-abụghị onye nduzi na onye nduzi.
3. Ihe ndị chọrọ nlebara anya:
1) Hypophosphorous acid bụ ihe na-ebelata maka nickel.Mgbe ọdịnaya dị elu, ngwa ngwa ntinye ga-abawanye na oyi akwa akwa ga-agba ọchịchịrị, ma nkwụsi ike nke ngwọta na-edozi ahụ ga-adị njọ, ọ ga-eme ka ọnụ ọgụgụ ọgbọ nke hypophosphite radicals dịkwuo elu, na ngwọta nke plating ga-adị mfe decompose.
2) Ka okpomọkụ na-abawanye, ntinye ntinye nke ngwọta plating na-abawanye.Mgbe okpomọkụ dị oke elu, n'ihi na ọnụ ọgụgụ nkwụnye ego na-adị ngwa ngwa, ihe ngwọta na-edozi ahụ na-adịkarị mfe ịmepụta onwe ya na ndụ ngwọta na-ebelata.
3) Uru pH dị ala, ihe ngwọta sedimentation ọsọ na-adị nwayọọ, na ọsọ ọsọ na-abawanye mgbe pH na-abawanye.Mgbe uru PH dị oke elu, a na-edobe mkpuchi ahụ ngwa ngwa ma ọ bụghị oke zuru oke, na ihe ndị dị na ya na-adịkarị mfe ịmepụta.
