1. Okwu mmalite

Na injinia ọgbara ọhụrụ na n'ichepụta, ntụkwasị obi nke nkwonkwo bolted dị oke mkpa maka iguzosi ike n'ezi ihe, nchekwa, na ịrụ ọrụ ogologo oge. Ihe nkedo ọdịnala na-enwekarị mmerụ ahụ, ọkachasị na gburugburu ebe siri ike metụtara mmiri, nnu, kemịkalụ, ma ọ bụ oke okpomọkụ. Dacromet flange bolts na-elebara ihe ịma aka ndị a anya site na ijikọta mkpuchi flake zinc-aluminom pụrụ iche yana uru ọrụ nke imepụta isi flange.

Dacromet flange bolt bụ ihe nkedo na-arụ ọrụ dị elu nke na-ejikọta ihe nrụnye arụrụ arụ dị ka flange n'okpuru isi ya na mkpuchi na-abụghị electrolytic zinc-flake nke a maara dị ka Dacromet (ma ọ bụ zinc flake mkpuchi usoro nke sitere na ya). Ngwakọta a na-enye nguzogide corrosion pụrụ iche, ike njigide na-agbanwe agbanwe, yana nnwere onwe pụọ na embrittlement hydrogen-na-eme ka ọ dabara adaba maka ngwa ike dị elu na ngalaba ụgbọ ala, ihe owuwu, mmiri, ike na ụlọ ọrụ mmepụta ihe.

2. Gịnị bụ mkpuchi Dacromet?

Dacromet bụ sistemu mkpuchi mkpuchi zinc-aluminom flake inorganic nke emebere na 1970s. Ọ nwere zinc na aluminom flakes kwụsịtụrụ n'ime ihe nkedo chromate (ma ọ bụ chromium na-enweghị). A na-etinye ihe mkpuchi ahụ site na ntinye-spin, spray, ma ọ bụ ụzọ imikpu wee gwọọ ya na okpomọkụ dị elu (nke dị ihe dịka 300 Celsius C), na-eme ihe nkiri nchebe dị gịrịgịrị, nke siri ike, nke nwere ọtụtụ ihe.

Njirimara isi nke mkpuchi ahụ gụnyere:

Ọkpụrụkpụ ihe nkiri dị obere: Ọ na-abụkarị 4-12 μm (nke na-adịkarị 6-8 μm), nke na-akwado nnabata eri.

Ihe mgbochi + nchebe ịchụ àjà: Ngwongwo ọla na-ekpuchi ekpuchi na-emepụta ihe mgbochi anụ ahụ ebe zinc na-enye nchebe galvanic (àjà).

Enweghị mmiri mmiri hydrogen: Usoro nke na-abụghị nke electrolytic na-ezere nchịkọta acid na electrolysis, na-ewepụ ihe ize ndụ nke nkwụsịtụ nke hydrogen na-egbu oge na ígwè ndị dị elu.

Nguzogide ọkụ: Kwụsie ike ruo ihe dịka 300°C okpomọkụ ọrụ na-aga n'ihu.

Ọdịdị: Ọla ọlaọcha-isi awọ matte imecha.

Rịba ama na "Dacromet" bụ aha azụmahịa; A na-eji usoro zinc-flake yiri nke ahụ (dị ka Geomet, nke na-enweghị chromium) taa iji zute ụkpụrụ gburugburu ebe obibi ọgbara ọhụrụ (RoHS, REACH, ELV).

3. Gịnị bụ Flange Bolts?

Ihe mkpuchi flange (nke a na-akpọkwa ihe mkpuchi isi hex flanged ma ọ bụ etiti bolt) na-egosipụta flange okirikiri dị n'okpuru isi hexagonal nke na-arụ ọrụ dị ka igwe eji arụ ọrụ. Nhazi a na-ekesa ibu clamping n'elu ebe buru ibu, na-ebelata ihe ize ndụ nke itinye n'ime ihe ejikọtara, na-eme ka iguzogide ịma jijiji dị nro, ma na-ewepụkarị mkpa maka ihe nhicha dị iche.

Ụdị nkịtị gụnyere:

Hex flange bolts (nke a na-ahụkarị)

bolts flange serated (ya na serrashi n'okpuru isi maka mgbochi ntụgharị)

Isi oghere ma ọ bụ ụdị flange ọpụrụiche ndị ọzọ

Mgbe ejikọtara ya na mkpuchi Dacromet, bolts ndị a na-enye ma arụmọrụ kachasị elu yana ịdịte aka gburugburu ebe obibi.

Tebụlụ na-esonụ na-achịkọta ụdị ọrụ dị iche iche:

Ngwongwo	Dacromet	Electro-Zinc	Hot-Dip Galv.	Igwe anaghị agba nchara
Mgbasa nnu (awa elekere)	1,000–1,500+	100–300	500–1,000+	pụta

Mara: arụmọrụ dị adị dịgasị iche na ọkwa mkpuchi, ọkpụrụkpụ, topcoat na ọnọdụ gburugburu ebe obibi. Sistemu flake zinc na-enweghị Chromium (dịka ọmụmaatụ, Geomet) na-enye nchebe corrosion yiri nke ahụ ka ọ na-emezu ụkpụrụ gburugburu ebe obibi siri ike.

5. Mpaghara ngwa ngwa

A na-eji bolts flange dacromet eme ihe na akụrụngwa chassis, sistemu nkwusioru, igwe igwe, mgbakọ breeki, sistemu iyuzucha na akụkụ ahụ. Ha na-anagide nnu n'okporo ụzọ, ịnya igwe ọkụ, ịma jijiji, na oke okpomọkụ n'okpuru mkpuchi ma na-enye ibu mwekota a pụrụ ịdabere na ya.

N'ime àkwà mmiri, ụlọ elu nnyefe, ihe owuwu ígwè, na ihe ndị dị n'ụsọ oké osimiri, bolts ndị a na-enye nchebe ogologo oge megide corrosion ikuku ma na-ebelata oge nhazi.

Ntọala turbine nke dị n'ụsọ osimiri, sistemu mgbago anyanwụ, iwu ụgbọ mmiri, na akụrụngwa ọdụ ụgbọ mmiri na-erite uru site na nguzogide nnu nnu dị elu na ikike ịkwa akwa geometries dị mgbagwoju anya n'otu n'otu.

Akụrụngwa ekpughere fatịlaịza, kemịkalụ, mmiri, na abrasion-dị ka igwe ọrụ ugbo, nfuli, valvụ, na akụrụngwa nhazi—na-akọwapụtakarị flange fasteners nwere mkpuchi Dacromet maka ogologo ndụ ọrụ.

6. Ọkwa nkịtị, ụkpụrụ, na ntụzịaka nhọrọ

Klas nke ihe onwunwe: Dacromet flange bolts dị na klaasị 4.8, 8.8, 10.9, na 12.9 (metric), yana ọkwa 5 na ọkwa 8 (imperial). Ọkwa dị elu (10.9/12.9) na-erite uru karịsịa site na enweghị ihe ize ndụ nke ikuku hydrogen.

Ụkpụrụ akụkụ: Ntụ aka na-agụnye ISO metric flange bolt standards, DIN, GB (Chinese), na ASME/ANSI maka usoro inch.

Nkọwa mkpuchi mkpuchi: A na-akọwakarị arụmọrụ site n'ịdị arọ mkpuchi opekempe (dịka, ọkwa A ≈ 24 g/m², Ọkwa B ≈ 36 g/m²) na ihe nfesa nnu chọrọ. Enwere ike ịgbakwunye uwe elu maka mma mmanye mmanye, agba, ma ọ bụ nchebe mgbochi ọzọ.

Atụmatụ nhọrọ: Dakọtara usoro mkpuchi na ụdị corrosion nke gburugburu ebe obibi (dịka, C3-C5 kwa ISO 12944). Maka nkwonkwo nhazi siri ike dị elu, kwado data torque-tension na mkpuchi na topcoat kpọmkwem. Họrọ sistemu na-enweghị chromium mgbe achọrọ nnabata gburugburu ebe obibi.

7. Nwụnye na Atụmatụ bara uru

Jiri nlezianya jikwaa: Ọ bụ ezie na mkpuchi ahụ nwere ezigbo adhesion, zere mmebi arụ ọrụ siri ike n'oge njikwa na ntinye.

Njikwa torque: Jiri ọnụọgụ esemokwu nke ndị na-ebu ihe mkpuchi nyere. Sistemụ Dacromet lubricated na-emepụta ibu mwekota na-agbanwe agbanwe karịa mkpuchi zinc enweghị mmanụ.

ndakọrịta: Dacromet na-adakọkarị na ọtụtụ gasket na ihe mkpuchi ma nwee ike ịse ya karịa ma ọ bụrụ na achọrọ ya.

Nyocha: Nlele anya maka mkpuchi na-aga n'ihu na nyocha adhesion (ebe akọwapụtara) kwesịrị ịbụ akụkụ nke njikwa mma.

8. Mmechi

Dacromet flange bolts na-anọchi anya ihe nrụgide tozuru oke na arụ ọrụ dị elu nke na-edozi nchebe corrosion pụtara ìhè, ntụkwasị obi n'ọrụ, na nhazi akụkụ. Site n'iwepụ ihe egwu ikuku hydrogen ka ha na-ebuga arụmọrụ nnu dị elu karịa plating zinc, ha abụrụla nhọrọ kacha amasị maka ịchọ ngwa n'ofe ụgbọ ala, ike, ihe owuwu na ngalaba ụlọ ọrụ.

Ka ụkpụrụ gburugburu ebe obibi na-aga n'ihu na-akwalite nnabata nke sistemụ zinc-flake na-enweghị chromium, teknụzụ na-aga n'ihu na-etolite ma na-ejigide uru ya. Mgbe a na-akọwa ihe nkedo maka gburugburu corrosive ma ọ bụ nke dị elu-karịsịa ebe a chọrọ akara ule dị elu-Dacromet (ma ọ bụ ihe yiri zinc-flake) nke a na-ekpuchi flange bolts kwesịrị ka a na-ewere nke ọma dị ka ihe ngwọta a nwapụtara na nke dị irè maka ndụ ọrụ nke mgbakọ ahụ.

A na-agba ndị injinia na ndị na-azụ ahịa ume ka ha kpọtụrụ ndị na-ebubata ihe mkpuchi maka mpempe data teknụzụ zuru ezu, ọnụọgụ esemokwu, na akụkọ nnwale ịgbasa nnu kpọmkwem maka sistemụ ahọpụtara yana chọrọ ngwa.

Enweghị. Na-esote.
