Dacromet Hex Socket Bolts: Igikoresho cyo Kurwanya Kurwanya Iterambere gihura nigishushanyo mbonera cyihuse

2026-07-27

Dacromet hex sock bolts yerekana guhuza tekinoloji ebyiri zikomeye zihuta: Dacromet ikora cyane murwego rwo kurwanya ruswa hamwe na silindrike ya sock-head (Allen) bolt geometrie. Hamwe na hamwe, batanga igisubizo cyihuse cyihanganira ibidukikije byangirika cyane mugihe gishobora gushyirwaho neza cyane, kugirango bibe ingenzi mumamodoka, inyanja, ubwubatsi, hamwe nimashini ziremereye kwisi yose.

1. Ikoranabuhanga rya Dacromet

Dacromet nuburyo bwihariye bwamazi ashingiye kubutaka bwa organic organique yatunganijwe muburyo bwa karubone hamwe nicyuma. Bitandukanye na zinc zisanzwe zikoresha amashanyarazi, Dacromet ikoresha imiti ya chromium idafite (cyangwa chromium nkeya) ikora imiti ihuza inzitizi nyinshi zifatanije na zinc na aluminium. Igisubizo nikintu cyihariye cya silver-imvi irangiza ihuza kutabogama kwiza hamwe nibikorwa bidasanzwe byo kurinda.

Ibice bitatu bikorana hamwe kugirango bitange uburinzi bwuzuye:

Zinc-aluminium flake base layer - itanga uburinzi bwibitambo (cathodic), ikabora cyane kugirango ikingire ibyuma byubatswe munsi, mugihe flake ya aluminiyumu yongeraho kurinda inzitizi.

Passivation rwagati - firime idasanzwe ya chromate / silikatike ifunga imiterere ya flake metallic, irwanya spray yumunyu, igitero cyimiti, nubushyuhe burenze kure ya zinc isanzwe.

Ikoti rya kashe yo hejuru (itabishaka) - yongerera imbaraga imbaraga zo gukumira no kurwanya ikirere, mugihe itanga ifeza-imvi ihoraho hamwe na coefficient nkeya yo guterana.

Imbonerahamwe 1. Kugereranya Kurwanya Kurwanya Kurwanya (Ikizamini cyumunyu, NSS)

Ubwoko bwo gutwikira	Amasaha yumunyu	Umubyimba (μm)	Porogaramu isanzwe
Dacromet	≥ 1.000 - 3.000	6 - 10	Marine / imodoka
Ruspert	≥ 1.000 - 3.000	3 - 5	Hanze / marine
Zn-Ni ibishishwa	20 720 - 1.000	8 - 12	Imodoka
Isahani isanzwe	96 - 240	5 - 8	Mu nzu / muri rusange

2. Hex Socket Bolts

Hex sock bolts, izwi kandi nka sock head cap screws cyangwa Allen bolts, igaragaramo umutwe wa silindrike hamwe na disiki y'imbere. Iyi geometrie yemerera itumanaho ryinshi hamwe numutwe muto ugereranije numutwe wa hex wo hanze, bigatuma biba byiza kubisabwa bifite aho bigarukira cyangwa aho bisabwa kugira isura nziza.

Ibintu by'ingenzi bishushanya birimo:

Umutwe wa Cylindrical hamwe na disiki yimbere - yemera urufunguzo rusanzwe rwa hex yo kwishyiriraho-torque nini hamwe n'umutwe muto; Ingano yimodoka ihuye na ISO 2936 cyangwa ASME B18.3.

Urudodo rwuzuye cyangwa igice - ibice-byuzuye-bigabura imitwaro iringaniye kuburebure bwasezeranijwe; Ibice-Urudodo Ibihinduka bitanga imbaraga zidasomwe shank yo gukata porogaramu.

Ibyuma bifite imbaraga nyinshi cyane (8.8 / 10.9 / 12.9) - amanota akoreshwa nubushyuhe atuma imbaraga zingana kugera kuri MPa 1,220, zibereye imitwaro yingirakamaro hamwe ningingo zikomeye.

Ubuso bwa Dacromet burangiza - butanga amasaha 1.000 yo kurinda umunyu-spray nta hydrogène yinjizwamo, bigatuma biba byiza cyane bifata imbaraga nyinshi aho amashanyarazi adakwiye.

Imbonerahamwe 2. Ibisanzwe Dacromet Hex Socket Bolt Ibisobanuro (Icyiciro cyumutungo 8.8)

Ingano	Umutwe Dia. (mm)	Uburebure bw'umutwe (mm)	Min. Tensile (MPa)	Porogaramu isanzwe
M4	4	4	800	Ibyuma bya elegitoroniki
M5	5	5	800	Inteko yoroheje
M6	6	6	800	Ibikoresho / imashini
M8	8	8	800	Imashini / imodoka
M10	10	10	830	Ihuriro ryubaka
M12	12	12	830	Imashini ziremereye

3. Incamake

Dacromet hex sock bolts ihuza imbaraga zo kurwanya ruswa ya sisitemu ya Dacromet idasanzwe (igera kumasaha 1.000.000 yo gukingira umunyu-spray nta hydrogène yinjizwamo) hamwe na torque-nini cyane, igishushanyo mbonera cya hex sock bolt. Uku kwishyira hamwe gutuma kwizerwa kwizerwa mubidukikije bisabwa - kuva sisitemu ya chassis na feri kugeza kumiterere yinyanja nibikoresho byo hanze - mugihe harinzwe kugenzura neza umuriro no kumara igihe kirekire. Mugihe inganda zigenda zisaba kwizirika kuringaniza imikorere, umutekano, no kuramba, Dacromet hex sock bolts yahindutse ihitamo kubashakashatsi na OEM kwisi yose.
