Mpụta nke teknụzụ Dacromet (nke a makwaara dị ka mkpuchi zinc-aluminom flake) na-enye ezigbo ngwọta maka ihe ịma aka a. Dacromet countersunk hex socket bolts na-ejikọta mkpuchi mgbochi corrosion zinc-aluminom dị elu yana nhazi nhazi oghere hex ziri ezi. Ọ bụghị nanị na ha na-enye ezigbo nguzogide corrosion na mgbochi nchara kamakwa na-ejigide ike ọrụ dị elu na ịdị mfe nke mgbakọ. Edemede a na-ewebata n'ụzọ zuru ezu njirimara teknụzụ yana uru ngwa nke Dacromet countersunk hex socket bolts site na echiche nke ụkpụrụ mkpuchi, nhazi ngwaahịa, uru mgbochi corrosion, ọnọdụ ngwa, na ndụmọdụ nhọrọ.

2. Nchịkọta nke teknụzụ mkpuchi mkpuchi Dacromet

Dacromet, nke a na-akpọkwa mkpuchi zinc-chromium ma ọ bụ mkpuchi zinc-aluminom, bụ teknụzụ ọgwụgwọ elu igwe anaghị arụ ọrụ nke ọma. Ultra-mma zinc flakes na aluminom flakes na-agwakọta ya na chromate na ndị ọzọ inorganic binders na-etolite a mmiri mkpuchi. A na-etinye ihe mkpuchi ahụ n'otu n'otu na mkpụrụ metal ahụ site n'itinye, fesa, ma ọ bụ brushing, wee gwọọ ya site na ikpo ọkụ dị elu iji mepụta akwa akwa mgbochi corrosion. Usoro a nke nwere ọtụtụ ihe mkpuchi zinc-aluminom flakes, jikọtara ya na ihe nkiri passivation chromate, na-emepụta ihe mgbochi pụrụ iche nke na-egbochi nnabata nke mmiri, oxygen na mgbasa ozi na-emebi emebi, si otú ahụ na-enweta ọmarịcha mgbochi corrosion na mgbochi nchara.

2.2 Isi Uru nke mkpuchi Dacromet

E jiri ya tụnyere omenala electro-galvanizing na ọkụ-mikpu galvanizing usoro, Dacromet mkpuchi na-enye nnukwu uru na mgbochi corrosion na nchara mgbochi:

• Nguzogide corrosion nnu na-efe efe dị elu: Ihe mkpuchi Dacromet ọkọlọtọ nwere ike idi awa 500-1500 ma ọ bụ karịa na nyocha nnu na-anọpụ iche, karịrị akarị eletrọ-galvanizing nkịtị (nke na-abụkarị naanị awa 72-200), na-agbatị ndụ ọrụ bolt na ihu igwe mmiri na gburugburu nnu na-emebi emebi.
• Ọ dịghị ihe ize ndụ nke hydrogen embrittlement: Omenala electroplating nwere ike iwebata hydrogen atom n'ime elu ígwè substrates ike dị elu, na-eme ka hydrogen embrittlement mgbaji. Dacromet bụ usoro na-abụghị nke electrolytic nke na-ewepụ ihe ize ndụ a kpamkpam, na-eme ka ọ dị mma maka bolts dị elu.
• Okpomọkụ dị elu na nguzogide ihu igwe dị mma: mkpuchi na-adịgide adịgide maka iji ogologo oge na gburugburu 250 Celsius ma nwee ike iguzogide okpomọkụ dị elu maka obere oge. Ọ na-egosipụtakwa nguzogide siri ike megide radieshon ultraviolet na okirikiri iru mmiri, na-eme ka arụ ọrụ mgbochi corrosion na-adịgide adịgide na mgbochi nchara.
• Ngwọta onwe onye na nchedo cathodic: Mgbe mkpuchi ahụ mebiri emebi na mpaghara, zinc na flakes aluminum na-eme ihe dị ka anodes ịchụàjà, na-enye nchebe electrochemical na mkpụrụ nke ekpughere ma na-emewanyewanye ikike mgbochi corrosion na nchara.

3. Atụmatụ nhazi nke Countersunk Hex Socket Bolts

Countersunk hex socket bolts (nke a makwaara dị ka screws skru hex flat-head) nwere njiri isi conical ma ọ bụ cylindrical countersunk. Mgbe echichi gasịrị, isi na-anọdụ ala kpamkpam n'ime countersink nke workpiece, na-enweta ebe dị nro, nke na-enweghị protrusion. Ụgbọ ala hex dị n'ime dị n'etiti isi, na-enye ohere ijikwa mkpịsị ugodi nke ọma na iwepụ ya mgbe ọ na-ebelata ihe ize ndụ nke ịpụpụ.

Nha ndị a na-ahụkarị sitere na M3 ruo M20 na dayameta buru ibu, na ogologo ha nwere ike ịhazi dịka achọrọ. Ihe na-abụkarị carbon steel, alloy steel, ma ọ bụ igwe anaghị agba nchara, a na-agwọ ọkụ iji nweta klaasị akụrụngwa dịka 8.8, 10.9, ma ọ bụ 12.9. Ọgwụ Dacromet na-enye nchebe zuru oke nke mgbochi corrosion na mgbochi nchara na-enweghị imebi eziokwu eri ma ọ bụ ihe eji arụ ọrụ, na-eme ka bolts ndị a dabara adaba maka ngwa na-achọ ma elu elu na nguzogide corrosion dị elu.
