Dacromet Flange Bolts–Mgbochi mgbochi corrosion Flange fasteners nwere Zinc-Aluminom flake mkpuchi 

Akụkụ 1 - Flange Bolt Overview

Kedu ihe bụ Flange Bolt?

Ihe mkpuchi flange bụ ihe mkpuchi isi hex nwere flange dị ka flange agbakwunyere na ala isi. Flange ahụ na-ekesa ibu nkedo n'elu ebe sara mbara, na-ebelata nrụgide elu na ihe ejikọrọ na igbochi mmebi nke ebe dị nro ma ọ bụ ihe osise. Nke a na-ewepụ mkpa maka ịsa akwa dị iche iche, na-eme ka mgbakọ dị mfe ma belata ọnụ ọgụgụ akụkụ.

Ngwakọta flange: Na-ekesa ike njide n'ofe mpaghara buru ibu karịa isi hex ọkọlọtọ, na-ebelata nrụgide ibu na igbochi ntinye elu.

Nhọrọ echekwabara: Flange dị n'okpuru na-ata ata n'elu mating, na-enye nguzogide ntọhapụ arụnyere na-enweghị ihe mkpuchi ọzọ.

Akụkụ ahaziri ahazi: Emepụtara ya na DIN 6921, ISO 4162, ma ọ bụ GB/T 5787, na-agba mbọ na-agbanwe agbanwe n'okirikiri ọkọnọ zuru ụwa ọnụ.

Ọkwa ike dị elu: Dị na klaasị 8.8 na 10.9, dabara maka ngwa nhazi na ibu ibu.

Nkebi 2 - Dacromet mkpuchi mkpuchi

Dacromet (达克罗) bụ ọgwụgwọ elu nke na-abụghị nke elektrọnik nke na-etinye ihe nkiri dị mkpa nke zinc na flakes aluminom jikọtara ya na ogige chromium inorganic. A na-etinye ya site na usoro ọgwụgwọ dip-spin-cure, ọ na-enye ọtụtụ ihe nchebe corrosion na-enweghị iwebata hydrogen n'ime ígwè - uru dị oke mkpa maka ihe ndị na-eme ka ike dị elu.

Usoro nchedo corrosion

Nchedo ịchụ àjà: Zinc flakes na-emebi emebi nke ọma iji chebe mkpụrụ nchara, ọbụlagodi mgbe a na-akpụcha mkpuchi ahụ.

Ihe mgbochi anụ ahụ: Ihe nkpuchi zinc-aluminom na-agbakọta na-emepụta ụzọ na-emerụ ahụ nke na-egbochi mmiri, oxygen, na ion corrosive.

ngafe kemịkalụ: Ngwakọta chromium na-etolite oyi akwa na-agafe agafe nke na-ebelata mgbasa nke zinc ma na-enye ọgwụgwọ onwe ya na micro-scratches.

Uru dị mkpa maka Flange Bolts

Enweghị mmiri mmiri hydrogen: Usoro na-abụghị electrolytic - nchekwa maka ọkwa 8.8-10.9 elu-ike flange bolts ebe electroplating na-egbochi.

Mkpa & uwe: 4–10 µm mkpuchi na-echekwa eri dabara na geometry flange. Ọnweghị ịpịgharị mkpụrụ osisi achọrọ.

Mgbasa nnu 500-1,200: 5-10 ugboro mma karịa ot zinc plating, adabara ogologo oge n'èzí ikpughe.
