Dacromet mkpuchi mkpuchi-Ntuziaka zuru oke maka teknụzụ mkpuchi mkpuchi zinc-Aluminom maka ngwakọ. 

1.Gịnị bụ Dacromet?

Emepụtara Dacromet na njedebe 1960 site n'aka ụlọ ọrụ America Diamond Shamrock (mgbe e mesịrị MCI, mgbe ahụ NDS / Doerken MKS). N'ịbụ nke e mepụtara iji lebara ọdịda hydrogen embrittlement ọdịda dị na ngwa ngwa ụgbọ ala dị elu, ọ ghọla ọkọlọtọ mkpuchi mgbochi corrosion zuru ụwa ọnụ, akọwapụtara n'okpuru ISO 10683, ASTM B695, na ụkpụrụ mba dị iche iche (GB/T 18684 na China).

Njirimara isi

Usoro na-abụghị electrolytic: A na-etinye dacromet site na mkpuchi dip-spin, ọ bụghị electroplating. Ọ dịghị ọkụ eletrik na-agafe akụkụ ndị ahụ, na-ewepụ ọgbọ hydrogen na ihe egwu ebrittlement metụtara.

Mkpuchi dabere flake: Ihe mkpuchi ahụ nwere zinc microscopic na flakes aluminum (20-60 nm) nke na-adaba dị ka shingle ụlọ, na-emepụta ihe mgbochi dị ukwuu, nke nwere ọtụtụ ihe.

Mkpa na uwe: Ọkpụrụkpụ mkpuchi a na-ahụkarị bụ 4-10 µm - dị gịrịgịrị iji chekwaa eriri dabara na nha nha, n'adịghị ka galvanizing na-ekpo ọkụ na-ekpo ọkụ.

Dabara gburugburu ebe obibi: Dacromet ọgbara ọhụrụ enweghị chromium hexavalent (Cr⁶⁺), izute RoHS, REACH, na ELV (Ụgbọ Ọgwụgwụ nke Ndụ).

Ọkụ na-eguzogide: Ihe mkpuchi inorganic na-eguzogide okpomọkụ ọrụ na-aga n'ihu ruo 250 ° C, na-eme ka ọ dị mma maka njin mmiri na ihe nkwụnye ọkụ dị n'akụkụ.

2. Key Uru

Nguzogide corrosion kacha elu: 500-1,200 awa nke nnu na-anọpụ iche (NSS) kwa ISO 9227 - 5-10 ugboro ka mma karịa zinc plating (96-240 awa).

Ọkpụkpụ hydrogen efu: Usoro na-abụghị nke electrolytic na-ewepu hydrogen absorption, na-eme ka Dacromet bụrụ ihe mkpuchi kachasị mma maka ihe nkedo dị elu (Grade 8.8-12.9) ebe a na-amachibido ma ọ bụ machibido electroplating.

Enyi mkpuchi mkpuchi mara mma: Mkpuchi mgbụsị akwụkwọ na-ekpuchi oghere, oghere kpuru ìsì, na geometry dị mgbagwoju anya karịa otu eletrọpụ ma ọ bụ ịgbanye ọkụ. Eriri crests na mgbọrọgwụ na-enweta mkpuchi na-agbanwe agbanwe.

Mkpuchi dị obere, nnabata echekwara: Na 4-10 µm, Dacromet anaghị egbochi njikọ eriri ma ọ bụ mmekọrịta nhụsianya. Ọnweghị ịpịgharị mkpụrụ osisi a chọrọ, n'adịghị ka ihe nkedo galvanized na-ekpo ọkụ.

Nguzogide ọkụ: Ihe mkpuchi seramiiki nke inorganic dị ka ihe mkpuchi na-ejigide ihe nchebe ya na okpomọkụ ruo 250 ° C (na-aga n'ihu) na 300 ° C (obere oge), nke karịrị ihe mkpuchi organic.

Nkwenye gburugburu: Enweghị Cr⁶⁺, kwekọrọ na ntuziaka RoHS, REACH na ELV. Mmiri mmiri na-ekpuchi mmiri nwere obere ikuku VOC ma e jiri ya tụnyere ihe ndị ọzọ dabere na ihe mgbaze.

Adhesion dị mma na nguzogide eyi: Ihe mkpuchi flake jikọtara kemịkalụ na-eguzogide nbibi, ịcha, na ijikwa mmebi nke ọma karịa plasta nke a na-emekarị.

3. Tụnyere na mkpuchi mkpuchi ndị ọzọ

Tebụl dị n'okpuru na-atụnyere Dacromet na ụzọ mkpuchi mkpuchi mkpuchi abụọ a na-ahụkarị - electroplated zinc plating na hot-dip galvanizing:

Nnu nnu kwa ISO 9227 NSS. Ihe ize ndụ mgbaka hydrogen na-emetụta ihe nkedo eletrọnịkị Ọkwa 10.9 na karịa.

4. Ngwa

Ụgbọala: Ihe mejupụtara injin, ihe nkwụnye chassis, sistemu breeki, akụkụ nkwusioru na ngwaike dị n'okpuru. A na-akọwa Dacromet site na ndị isi OEM (VW, Toyota, GM, Ford) maka bolts dị elu (Grade 8.8-10.9) ebe a ga-ezere embrittlement hydrogen.

Ihe owuwu & akụrụngwa: Njikọ nhazi igwe, ngwaike àkwà mmiri, ihe nkwụnye ọwara, yana njikọ ihe arụrụ arụ nke ekpughere na gburugburu iru mmiri na ihe rụrụ arụ.

Eletriki & ike: Ihe mkpuchi ụlọ elu na-ebufe, ngwa mgba ọkụ ọkụ, na ihe mkpuchi ọkụ eletrik chọrọ ịdịte aka n'èzí ogologo oge.

Ụgbọ okporo ígwè & ụzọ njem: Ihe ngbochi ngwaahịa na-agbagharị agbagharị, ihe ndị na-egwu egwu, na ngwaike akụrụngwa nrịbama ekpughere na nnu na-emebi emebi na ikuku ikuku.

Mmiri & osimiri: Akụrụngwa n'ọdụ ụgbọ mmiri na ọdụ ụgbọ mmiri, ihe nkwụnye ikpo okwu nke dị n'ụsọ osimiri, na akụrụngwa dị n'ime ikuku jupụtara nnu (tinyere akwa mkpuchi mkpuchi maka nchebe kachasị).

Ike ikuku: bolts ụlọ elu flange, ngwa nacelle, na bolts arịlịka ntọala na-achọ ọtụtụ iri afọ nke nchebe corrosion na-enweghị mmezi.

Ngwa & HVAC: Ihe nkwụnye ọkụ na-agbanwe ọkụ, ihe ọkụ ọkụ, na ngwaike dị n'èzí ebe a na-achọrọ ihe abụọ na-eguzogide okpomọkụ na nchebe corrosion.

Nchịkọta

Dacromet bụ teknụzụ mkpuchi mkpuchi corrosion na-arụ ọrụ dị elu maka igwe nchara. Ọdịdị ya pụrụ iche zinc-aluminom flake Ọdịdị, etinyere site a na-abụghị electrolytic dip-spin usoro, na-anapụta 500-1,200 awa nke nnu na-eguzogide na-enweghị hydrogen embrittlement - na-eme ka ọ bụ mkpuchi nke nhọrọ maka elu-ike bolts na ụgbọ ala, ihe owuwu, na ike ngalaba. Site na ihe nkiri ya dị gịrịgịrị, nke edo edo, nnabata gburugburu ebe obibi, yana ezigbo nguzogide okpomọkụ, Dacromet na-ejikọ ọdịiche dị n'etiti igwe anaghị agba nchara dị ọnụ ala na igwe anaghị agba nchara, na-enye nguzozi kachasị mma nke arụmọrụ, ntụkwasị obi na ọnụ ahịa maka ngwa ngwa ngwa ngwa.
