Dacromet-Yashizweho Hexagon Socket Countersunk Umutwe Bolts

2026-11-02

Dacromet yometse kuri hexagon sock countersunk umutwe wa bolt ikomatanya umutwe wa flush ikwiranye na flinc hamwe na flake ya zinc-aluminiyumu itanga amasaha 720-1000 yo kurwanya umunyu-gutera - inshuro nyinshi kurenza amashanyarazi asanzwe ya zinc. Iyi ngingo isobanura Bolt geometrie, uburyo bwo gutwikira Dacromet, uburyo bwayo bwo kurwanya ruswa, nuburyo igereranya nubundi buryo bwo kuvura ingese kumashanyarazi na bolts.

1. Intangiriro: Impamvu Kurinda Ruswa Ibyingenzi kuri Bolts na Screw

Kwizirika - Bolts, screw, nuts, hamwe nogeshe - nibintu byangirika cyane kwangirika mubice byose byahujwe. Bolt yangiritse itakaza preload, ifata mu mwobo wacyo, kandi amaherezo ibangamira ubusugire bwimiterere yinteko yose. Mu bidukikije byo mu nyanja, ibiraro by’imihanda, imiterere y’izuba, hamwe n’imashini zo hanze, imigozi isanzwe ya zinc irashobora kwerekana ingese zera mu byumweru hamwe n'ingese zitukura mu mezi.

2. Ibicuruzwa Geometrie: Hexagon Socket Countersunk Umutwe Bolt

Ingano yumutwe	Umutwe Diameter (dk)	Uburebure bw'umutwe (k)	Hex Socket (s)	Icyiciro Cyimbaraga Icyiciro	Uburebure busanzwe
M5 × 0.8	10.0 mm	Mm 2.8	4 mm	8.8 / 10.9	Mm 10-60
M6 × 1.0	11,4 mm	3,3 mm	5 mm	8.8 / 10.9	Mm 12-80
M8 × 1.25	15.0 mm	4,4 mm	Mm 6	8.8 / 10.9	Mm 16-100
M10 × 1.5	18,5 mm	5.4 mm	8 mm	8.8 / 10.9	Mm 20-120
M12 × 1.75	21,5 mm	6.5 mm	Mm 10	8.8 / 10.9	Mm 25-150

Ibyiza bya geometrie y'ubwoko bwa screw:

Dacromet-Yashizweho Hexagon Socket Countersunk Umutwe Bolts

Ubuso bwuzuye- umutwe wa comptersunk ntusohoka, ukuraho ingingo zifatika no kwemerera ibice byo gushyingiranwa kwicara hejuru.
Ubushobozi bwo hejuru- hexagon sock ikoresha amasura atandatu yo guhuza, yohereza umuriro wa 30-50% kurenza moteri ya Phillips cyangwa Phillips mbere yo kwiyambura.
Gusezerana kumutwe- imashini yuzuye yimashini (cyangwa kwikubita inshusho kumpapuro zicyuma) zitanga imbaraga zikomeye zifatika zifatanije.

3. Ipitingi ya Dacromet: Uburyo ikora

Dacromet nizina ryanditswemo ryahindutse ijambo rusange ryinganda zinc-aluminium flake ushyizwemo na dip-spin cyangwa spray hanyuma ukira hafi 300 ° C. Bitandukanye na electroplating, inzira ntabwo ari electrolytike, bityo igifuniko ntigishobora kwinjiza hydrogène - ikintu gikomeye cyumutekano muke wimbaraga zikomeye zo murwego rwa 10.9 no hejuru.

Igipfundikizo ni materique yijimye yijimye ya zinc na aluminiyumu (mubisanzwe 0.1-0.5 µm z'ubugari, 15-20 µm byose) bihujwe na chromium idasanzwe. Uburyo bwayo bwo kurwanya ruswa ni butatu:

4. Imikorere yo kurwanya ruswa: Amakuru yumunyu

Ikizamini cyibipimo byihuta byo kurwanya ingese ni ikizamini cyumunyu utabogamye (NSS) kuri ISO 9227 / ASTM B117. Imbonerahamwe 3 igereranya imigozi isize Dacromet hamwe nubuvuzi busanzwe bwo kuvura.

Imbonerahamwe 3 - Kugereranya kurwanya ruswa (ikizamini cya NSS, amasaha kugeza ingese itukura)

Kuvura Ubuso	Ubunini busanzwe	Ingese yera	Umutuku	Amazi ya Hydrogen	Igipimo cyibiciro
Gusiba zinc (Zn)	5-8 µm	24-96 h	150-300 h	Hagati	1.0
Isahani yumuhondo (Zn-Cr)	5-8 µm	96–200 h	300-500 h	Hagati	1.2
Ashyushye cyane (HDG)	50–100 µm	—	1.000.000 h	Hasi	1.5
Dacromet (ikoti 1)	5-8 µm	480–720 h	720–1,000 h	Nta na kimwe	1.8
Dacromet (amakoti 2-3)	10-24 µm	1.000+ h	1.500-25.500 h	Nta na kimwe	2.2
Dacromet + hejuru-kashe	10-24 µm	1.200+ h	2000-3000 h	Nta na kimwe	2.5

5. Umwanzuro

Dacromet yubatswe na hexagon sock countersunk umutwe wa bolt ikemura ibibazo bibiri bishaje mugufatisha urudodo - ingese no gusohoka - mubice bimwe. Ububiko bwa geometrike butanga isuku, isukuye, idafite urusenda hamwe na moteri ya hexagon ifite umuvuduko mwinshi, mugihe icyuma cya zinc-aluminium gitanga igitambo nimbogamizi zo kurwanya ruswa kirinda amasaha 1.000 cyangwa arenga mugupima-gutera umunyu, nta hydrogene yinjizwamo. Kuri ba injeniyeri n'abaguzi bagaragaza imigozi n'ibiti byo hanze, inyanja, cyangwa ubwikorezi bwo gutwara abantu, iki cyiciro cyihuta gitanga kimwe mubintu byiza byangirika-birinda-kugiciro kiboneka muburyo bwa tekinoroji ya bolting.
