Dacromet Flange Bolts: Arụmọrụ mgbochi corrosion kacha elu maka ngwa ngwa ngwa ngwa 

Uru ndị bụ isi nke Flange Bolts nwere mkpuchi Dacromet

Mgbe etinyere Dacromet na flange bolts, nchikota nke nkesa ibu geometric na nchedo elu dị elu na-enye usoro ngwa ngwa nke kachasị na ọnọdụ ọrụ na-achọsi ike. Uru ndị bụ isi gụnyere:

Nrụrụ pụrụiche na Nguzogide nchara

Nnwale ụlọ nyocha onwe onye dabere na ASTM B117 na ISO 9227 na-egosi na mkpuchi Dacromet etinyere nke ọma na flange bolts nwere ike iguzogide ihe karịrị awa 1,000 nke ikpughe ịgba nnu na-anọpụ iche na-enweghị nchara na-acha ọbara ọbara. N'ọtụtụ usoro, ngwaahịa corrosion ọcha na-adị ntakịrị ọbụlagodi mgbe ekpughere ogologo oge. Ọmụmụ ihe atụnyere na-egosi Dacromet na-eme ka zinc plating na-emebu site n'ihe dị ka asaa ruo iri na karịa galvanizing na-ekpo ọkụ n'ime ihe nkiri dị mkpa na nkwụsi ike ogologo oge. Ndụ ọrụ n'ezie na ikuku mmiri, mmiri, na ụlọ ọrụ mmepụta ihe na-adịkarị karịa afọ iri na ise ruo iri abụọ mgbe akọwapụtara ma tinye usoro mkpuchi ahụ nke ọma.

Nnwere onwe pụọ na mgbami hydrogen

Ihe mgbochi flange dị elu na-enwe mmetụta karịsịa maka mgbawa hydrogen kpatara. N'ihi na usoro Dacromet bụ kpamkpam na-abụghị nke electrolytic ma na-ezere nkwadebe elu acidic, ọ dịghị hydrogen atomiki na-emepụta ma ọ bụ tinye n'ime microstructure ígwè. Nnwale iru eru na ASTM A490 bolts structural na akara ule dị elu yiri nke ahụ ekwenyela na Dacromet anaghị ewebata embrittlement hydrogen n'ime ma ọ bụ na-akwalite mmechi hydrogen gburugburu n'okpuru ọnọdụ ọrụ.

Mkpuchi uwe dị mkpa, dakọtara na eriri ziri ezi

Ụdị ihe nkiri Dacromet na-ahụkarị nke 5-12 µm dị gịrịgịrị karịa galvanizing na-ekpo ọkụ (na-abụkarị 50-80 µm). N'ihi ya, eriri eriri na mgbọrọgwụ radii na-anọgide n'ụzọ ziri ezi, na-ekwe ka mkpụrụ osisi na-agbakọta nke ọma na-enweghị mkpa maka nnukwu taps ma ọ bụ nkwụnye ụgwọ ụgwọ. Ihe mkpuchi ahụ na-abanyekwa n'ebe ezumike, n'okpuru isi ihe, na flange n'okpuru isi nke bolt, na-enye mkpuchi mgbochi corrosion na-aga n'ihu ebe ịkwa akwa nwere ike ịhapụ mpaghara dị nro ma ọ bụ porous.

Nkwụsi ike nke okpomọkụ na ịdịte aka n'ibu

Dacromet na-edobe iguzosi ike n'ezi ihe nchebe na okpomọkụ ọrụ na-aga n'ihu ruo ihe dịka 300 Celsius ma na-anabata mkpughe oge dị mkpirikpi karịa ọnụ ụzọ ahụ. Ihe mkpuchi ahụ na-egosiputa nrapanye dị mma, nguzogide abrasion n'oge njikwa na nrụnye, yana mmanu a na-achịkwa nke na-enye aka na mmekọrịta nhụsianya na-agbanwe agbanwe-karịsịa bara uru maka mgbakọ flange bolt ebe preload otu dị oke mkpa.

Nrube isi na gburugburu ebe obibi na usoro iwu

Dị ka usoro mmiri na-enweghị cadmium, ndu, na (na usoro ọgbara ọhụrụ) nchegbu chromium hexavalent mgbe ejiri ya nke ọma, Dacromet na-akwado nrube isi na ntuziaka RoHS, REACH, na ELV. Usoro a na-ebute ntakịrị ihe mkpofu dị ize ndụ ma e jiri ya tụnyere ahịrị electroplating ọdịnala, na-adakọ na ihe nkwado dị ugbu a maka ngwa ngwa ụlọ ọrụ.

Ebe ngwa ngwa maka Dacromet Flange Bolts

Ngwakọta pụrụ iche nke ntụkwasị obi dị elu na arụmọrụ mgbochi nchara ogologo oge na-eme ka Dacromet flange bolts bụrụ nhọrọ kachasị amasị n'ofe ọtụtụ ụlọ ọrụ:

Akụrụngwa na injinia obodo: Ngwunye mgbasawanye akwa akwa, ụlọ ndị nwere nchara, ụlọ elu nnyefe, na ihe owuwu dị n'akụkụ osimiri nke ekpughere na mbara ikuku nwere chloride.
