2. Gịnị bụ mkpuchi Dacromet?

Dacromet bụ usoro mkpuchi zinc-aluminom flake na-arụ ọrụ dị elu nke emepụtara dị ka ihe dị elu na-agbanwe agbanwe na electroplating ọdịnala na ịgbanye ọkụ na-ekpo ọkụ. Ihe mkpuchi ahụ nwere akwa zinc na flakes aluminom na-ekpuchi ekpuchi n'ime ihe nkedo inorganic. Mgbe etinyere ya site na ụzọ ntuba-spin, ịgba, ma ọ bụ itinye mmiri na ọgwụgwọ okpomọkụ dị elu, flakes na-etolite ihe mgbochi dị ukwuu, nke nwere ọtụtụ ihe na-enye ọtụtụ usoro nke. mgbochi corrosion nchebe.

N'adịghị ka platin zinc a na-emekarị nke na-adabere na otu oyi akwa ọla na-aga n'ihu, usoro lamellar nke zinc na flakes aluminum na-emepụta ụzọ mgbagwoju anya nke na-ebelata ntinye mmiri, oxygen, na ion chloride. Microstructure a pụrụ iche na-etolite ntọala nke mkpuchi mkpuchi iguzogide corrosion na-adịte aka mgbochi nchara ike. Ọkpụrụkpụ mkpuchi Dacromet a na-ahụkarị sitere na 5 ruo 12 micrometers (μm). N'agbanyeghị profaịlụ ya dị gịrịgịrị, oyi akwa Dacromet etinyere nke ọma nwere ike nweta nguzogide nnu nnu karịa awa 1,000 - yana mgbe karịa awa 2,000 - na-enweghị ọdịdị nchara na-acha ọbara ọbara. Nke a larịị nke mgbochi nchara arụmọrụ karịrị ihe mkpuchi elektrọn-galvanized a na-emekarị ma na-egosipụtakarị galvanizing na-ekpo ọkụ na cyclic na ule mkpughe ogologo oge.

3. Isi uru nke Dacromet Flange Bolts

Dacromet flange bolts na-ejikọta ntụkwasị obi igwe na nke ka elu mgbochi corrosion ogologo oge, na-eme ka ha dị mma maka ngwa ike dị elu na nke dị oke egwu.

3.1 Mgbochi nrụrụ pụtara ìhè yana arụrụ nchara

Isi ihe kpatara ịhọrọ bolts flange mkpuchi Dacromet bụ ihe pụrụ iche ha iguzogide corrosion. Nnwale ịgba nnu nwere onwe (ASTM B117 / ISO 9227) na-egosi mgbe niile na mkpuchi Dacromet na-eguzogide 1,000 ruo 2,000 awa ma ọ bụ karịa tupu nchara uhie apụta. Ntụle atụnyere na-egosi na Dacromet na-enyekarị 3 ruo 10 mma mgbochi nchara arụmọrụ karịa ọkọlọtọ zinc electroplating. Nke a dị elu mgbochi nchara ike tụgharịrị gaa na ndụ ọrụ gbatịpụrụ nke ukwuu maka njikọ flange ekpughere na gburugburu ebe ike dị ka oke osimiri, mmiri mmiri, na ikuku ụlọ ọrụ mmepụta ihe.

3.2 Enweghị ihe ize ndụ nke mgbaka hydrogen

Ihe mgbochi flange siri ike dị elu (akara 8.8, 10.9, 12.9 na ASTM A490 / F3125 bolts nhazi) na-enwe mmetụta nke ukwuu maka mwepu hydrogen. Omenala electroplating na-agụnye ịchịkọta acidic na ntinye electrolytic nke nwere ike iwebata hydrogen n'ime ígwè ahụ, na-etinye mgbaji na-egbu oge. Dacromet bụ usoro na-abụghị nke electrolytic nke na-ezere ihe ize ndụ a, na-eme ka bolts na-agwọ Dacromet bụrụ nke kachasị mma. mgbochi corrosion ngwọta maka elu-tensile flange bolts.

3.3 mkpuchi dị nro na ndakọrịta eriri mara mma

N'ụdị ọkpụrụkpụ nke naanị 5-12 μm, ihe nkiri Dacromet anaghị agbanwe oke eri ma ọ bụ gbochie itinye aka na nut. N'ụzọ dị iche, galvanizing na-ekpo ọkụ na-emepụtakarị akwa mkpuchi na-enweghị isi nke na-ejupụta eri ma na-achọ mkpụrụ osisi buru ibu. Ya mere, enwere ike iji mkpụrụ osisi chịkọta dacromet flange bolts ka ọ ka na-ebuga ndị pụtara ìhè iguzogide corrosion na mgbochi nchara nchebe.

3.4 Nkwụsi ike dị elu na nchekwa ọtụtụ usoro

Ihe mkpuchi dacromet na-echekwa ha mgbochi corrosion iguzosi ike n'ezi ihe na okpomọkụ dị elu (nke na-eru 250-300 Celsius C), nke bara uru maka flange bolts dị nso na engines, usoro ikpochapu, ma ọ bụ ihe dị n'èzí. Ihe mkpuchi ahụ na-enye nkwado anọ mgbochi nchara usoro: (1) Mgbochi mgbochi site na nkpuchi zinc-aluminom flakes; (2) Nchekwa ịchụ àjà Galvanic site na zinc; (3) Mmetụta na-edozi onwe ya site na njuputa oxide nke obere mmebi; na (4) ngafe site na ihe nkedo inorganic nke na-akwụsị n'ihu n'ihu corrosion.

4. Ngwa a na-ahụkarị nke Dacromet Flange Bolts

N'ihi nke ọma ha mgbochi corrosion na mgbochi nchara Njirimara, Dacromet flange bolts na-akọwapụta nke ọma n'ofe ụlọ ọrụ chọrọ ntụkwasị obi ogologo oge n'okpuru ọnọdụ mmebi:

Nrụpụta ike na nnyefe: Ihe mkpuchi ụlọ elu na akụrụngwa ọkụ na-adabere na Dacromet mgbochi ncharaarụmọrụ na gburugburu n'èzí.
Igwe dị arọ, ọrụ ugbo na ihe owuwu: Akụrụngwa na-arụ ọrụ na ala mmiri mmiri, fatịlaịza, ma ọ bụ ikuku mmiri dabere na Dacromet iguzogide corrosionna ogologo oge mgbochi nchara.

5. Nchịkọta uru na mmechi

Ịhọrọ ihe mkpuchi flange nke Dacromet na-eweta ọtụtụ uru bara uru:

Emelitere nke ọma iguzogide corrosionna mgbochi nchara arụmọrụ ma e jiri ya tụnyere ihe mkpuchi zinc a na-ahụkarị.
Ogologo oge mmezi ogologo yana belata ọnụ ahịa okirikiri ndụ n'ihi ịgbatị ogologo mgbochi nchara.
Ngwa dị mma na bolts ike dị elu na-enweghị ihe egwu embrittlement hydrogen.
Nchekwa nke geometry eri ziri ezi maka mgbakọ a pụrụ ịdabere na ya na ijikwa ya eme ihe.
Arụmọrụ dị oke mma na gburugburu nnu, iru mmiri, kemịkalụ na oke okpomọkụ.

Na mmechi, Dacromet flange bolts na-anọchite anya ihe tozuru oke, ihe ngwọta dị elu maka ndị injinia na ndị ọkachamara na-arụzi ọrụ na-achọ ma ntụkwasị obi na usoro dị elu. mgbochi corrosion nchebe. Site na nchikota pụrụ iche nke nchebe mgbochi, ọrụ zinc ịchụ àjà, omume ọgwụgwọ onwe onye, na ngafe inorganic, mkpuchi Dacromet na-ebuga pụrụ iche. iguzogide corrosion, pụtara ìhè mgbochi nchara ike, na ogologo oge mgbochi nchara. Ma ejiri ya na igwe ikuku ikuku, akụrụngwa dị n'ụsọ oké osimiri, chassis ụgbọ ala, osisi petrochemical, ma ọ bụ akụrụngwa ụlọ ọrụ dị arọ, flange flange nwere mkpuchi dacromet na-egosipụtakarị ọgwụgwọ elu ala ọdịnala na ịdịte aka na ntụkwasị obi.

Maka njikọ flange dị oke egwu ekpughere na ọnọdụ ọrụ rụrụ arụ, ịkọwapụta Dacromet flange bolts bụ mkpebi teknụzụ dị mma nke na-eme ka nchekwa dịkwuo mma, na-ebelata ụgwọ ọrụ ndụ, ma na-eme ka nguzosi ike n'ezi ihe na-adịgide adịgide site na elu. iguzogide corrosion na a pụrụ ịdabere na ya mgbochi nchara.

Enweghị. Na-esote.
