GEOMET® (Jumete) Ihe mkpuchi Hexagonal Bolts-Mwebata nka nka 

1. Okwu Mmalite na GEOMET® (久美特) mkpuchi

GEOMET® (nke a na-akpọkarị na Chinese dị ka 久美特 ma ọ bụ Jumete) bụ ihe mkpuchi flake na-enweghị chromium, nke dabeere na zinc-aluminom nke NOF Metal Coatings Group mepụtara dị ka onye na-anọchi anya gburugburu ebe obibi na usoro DACROMET® ọdịnala. Ọ na-enye nchebe corrosion pụtara ìhè maka ihe nchara ígwè, ọkachasị bolts hexagonal, ebe ọ na-erube isi n'iwu gburugburu ebe obibi ọgbara ọhụrụ dịka RoHS, REACH, ELV (2000/53/EC), na ISO 10683.

Ihe mkpuchi ahụ nwere zinc na flakes aluminom na-agafe site na matriks inorganic. Tinyere ya site n'ụzọ dip-spin ma ọ bụ ịgbasa wee gwọọ ya na obere okpomọkụ, GEOMET® na-emepụta ihe nkiri ọlaọcha na-acha ntụ ntụ (nke na-abụkarị 6-12 μm) nke na-adịghị emetụta akụkụ eri ma ọ bụ dabara. N'ihi na usoro a na-abụghị electrolytic, ọ na-ewepụ kpamkpam ihe ize ndụ nke hydrogen ebrittlement-uru dị mkpa maka elu-ike bolts (Klas 8.8, 10.9 na 12.9).

2. Mechanical ike → họrọ ihe onwunwe klas 8.8, 10.9 ma ọ bụ 12.9 dị ka ibu na nchekwa ihe.
3. Ụdị eriri → eriri akụkụ (ISO 4014) maka nkwonkwo dị oke egwu; eri zuru oke (ISO 4017) maka ntinye aka kacha.
4. Ọnụọgụ esemokwu → ezipụta uwe elu PLUS® ma ọ bụrụ na mmekọrịta ọgbaghara na-achịkwa dị oke mkpa.
5. Ihe chọrọ gburugburu ebe obibi & usoro iwu → GEOMET® na-eju RoHS, REACH na ELV na-enweghị ihe mgbakwunye ọzọ.

4.3 ndetu mmesi obi ike

Ndị na-achọ mkpuchi mkpuchi a ma ama na-edobe asambodo usoro (ISO 9001) ma na-ejidekwa nkwado OEM (Toyota, GM, wdg). Ekwesịrị ịnwapụta ọkpụrụkpụ mkpuchi mkpuchi, adhesion (nnwale teepu), arụmọrụ nnu na ọnụ ọgụgụ esemokwu dị ka ISO 10683 na eserese ndị ahịa si dị. Ọdịdị a na-ahụ anya bụ ọla ọcha na-acha ntụ ntụ edo edo; variants ojii (GEOBLACK®) dịkwa mgbe ihe ịchọ mma ma ọ bụ njirimara chọrọ ya.

5. Nkwubi okwu

GEOMET® (久美特) mkpuchi hexagonal nwere mkpuchi na-ejikọta ntụkwasị obi a nwapụtara nke ọma nke ihe mkpuchi isi hex-isi nke ISO nwere mkpuchi mkpuchi zinc-aluminom na-enweghị chromium nke na-enye nchebe pụrụ iche, nnabata gburugburu ebe obibi na nnwere onwe pụọ na hydrogen embrittlement. Ma ejiri ya na chassis ụgbọ ala, nchara arụrụ arụ ma ọ bụ igwe mmepụta ihe, ihe nkedo ndị a na-enye usoro teknụzụ dị elu yana ihe akaebe ga-eme n'ọdịnihu maka ngwa chọrọ.

Maka ndụmọdụ ndị akọwapụtara nke ọma, nkọwa mkpuchi ma ọ bụ data akụrụngwa akụrụngwa, lelee ụkpụrụ ISO dị mkpa (4014, 4017, 898-1, 10683) yana mpempe data teknụzụ nke NOF Metal Coatings Group nyere ma ọ bụ ndị ntinye ikike ikike.
