Dacromet Hexagonal Bolts- Mgbochi mgbochi dị elu & Ngwọta Mgbochi Mgbochi Mgbochi 

2. Gịnị bụ mkpuchi Dacromet?

Dacromet bụ ihe mkpuchi zinc-aluminom flake nke emepụtara dị ka ihe ọzọ dị elu maka ịgbanye ọkụ eletrik. Ihe mkpuchi ahụ nwere ihe mkpuchi zinc na-ekpuchi na flakes aluminom n'ime ihe nkedo inorganic. Mgbe etinyere ya na bolts hexagonal wee gwọọ ya n'ihe dịka 300 Celsius, ọ na-etolite ihe mgbochi dị ukwuu, nke nwere ọtụtụ ihe na-ebupụta ihe pụtara ìhè. mgbochi nchara na mgbochi corrosion arụmọrụ.

Isi njirimara nke mkpuchi Dacromet na bolts:

• Ihe nkiri dị obere: A na-ahụkarị naanị 4-12 μm (mgbe ọ na-abụkarị 6–8 μm), na-echekwa jiometry eri na dabara na bolts hexagonal ziri ezi.
• Ihe mgbochi + nchebe ịchụ àjà: Zinc laminated na flakes aluminum na-egbochi mmiri / oxygen ma na-enye nchebe galvanic (àjà) nke mkpụrụ nchara.
• mkpuchi uwe: Ngwa ntupu ma ọ bụ ịgbasa na-eme ka mkpuchi dị mma na geometry dị mgbagwoju anya, gụnyere eriri miri emi na isi hexagonal.
• Ọdịdị: Uniform metallic silver-gray matte finish, dabara adaba maka arụ ọrụ na ihe ịchọ mma.

3. Isi uru nke Dacromet Hexagonal Bolts

Nguzogide nrụrụ pụrụiche & arụrụ nchara mgbochi

Uru bụ isi nke bolts hexagonal nwere mkpuchi Dacromet bụ pụtara ìhè iguzogide corrosion na ogologo oge mgbochi nchara ike. N'agbanyeghị mkpuchi dị obere nke naanị 4-8 μm, bolts ndị a na-eguzogide ule ịgba nnu na-anọpụ iche (ASTM B117 / ISO 9227) karịa awa 1,000 - yana mgbe mgbe 1,200 ruo ihe karịrị awa 2,000 - na-enweghị nchara uhie. Nke a na-adịkarị 7-10 ugboro mma karịa ot electro-galvanizing (100-300 awa) na asọmpi na ma ọ bụ karịa ọtụtụ thicker na-ekpo ọkụ-mikpu galvanized galvanized.

Ihe owuwu dị iche iche nke zinc-aluminom flake na-egbochi mmiri, oxygen, na chlorides. Ọbụlagodi na mpaghara mebiri emebi, ihe ịchụ aja nke zinc na-aga n'ihu na-echebe mkpụrụ osisi bolt, na-abawanye n'ozuzu ya. mgbochi nchara. Nke a na-eme Dacromet hexagonal bolts dị mma maka oke osimiri, mmiri, ụgbọ ala na gburugburu ụlọ ọrụ mmepụta ihe.

Ihe ize ndụ embrittlement efu efu

Uru dị oke mkpa maka bolts hexagonal dị elu bụ enweghị ihe egwu embrittlement hydrogen zuru oke. Electroplating na-ewebata hydrogen atọm n'ime ígwè, nke nwere ike ime ka mgbaji na-egbu oge na klaasị 10.9, 12.9, yana bolts nhazi dịka ASTM A490. Dacromet bụ onye na-abụghị electrolytic ma na-ezere pickling acid ike ike, n'ihi ya, ọ dịghị hydrogen ka ewebata. Dacromet dị elu bolts ya mere, achọ ka ọ dịghị post-plating baking na-enye elu pụrụ ịdabere na nchekwa-dị oké egwu nkwonkwo. Ọtụtụ OEM ụgbọ ala na-akọwapụta Dacromet ma ọ bụ mkpuchi zinc-flake dabara adaba maka nke a.

Nguzogide oke okpomọkụ

Ihe mkpuchi dacromet na-edobe iguzosi ike n'ezi ihe na mgbochi corrosion ịrụ ọrụ na okpomọkụ na-aga n'ihu ruo 300 ° C. Electroplating zinc a na-ahụkarị na-eweda n'elu 100-120 Celsius C, ebe galvanizing na-ekpo ọkụ nwere oke ala dị elu. Nkwụsi ike a na-ekpo ọkụ dabara Dacromet hexagonal bolts maka ngalaba injin, sistemu iyuzucha, oven ụlọ ọrụ mmepụta ihe, na akụrụngwa na-emepụta ike ebe ma ike njigide na ogologo oge. mgbochi nchara achọrọ.
