Dacromet-Yashizweho Hex Bolts

2026-10-27

1. Intangiriro

Igice cyose gihindagurika ni intambara yo kurwanya ruswa. Hex bolt (hexagon head cap screw) irashobora kuba yihuta cyane kwisi, ariko iyo imaze gushyirwa mubiraro, umunara wogukwirakwiza, cyangwa uruganda rukora imiti, ihita yibasirwa nubushuhe, ogisijeni, ion ya chloride, na dioxyde de sulfure. Ingese - ubanza ingese (ibicuruzwa bya okiside ya zinc), hanyuma ingese itukura .

Ipitingi ya Dacromet (nanone yitwa DACROMET, igipande cya zinc-flake, cyangwa icyuma kitari electrolytike zinc-aluminium flake coating) yakozwe neza kugirango itsinde iyi ntambara. Itanga ibishishwa bya hex, sitidiyo, hamwe nuduce twa hex hamwe nogeshe intwaro yoroheje, imwe, idafite hydrogène idafite ubuzima burenga amasaha 700 yo kwipimisha umunyu utabogamye (NSS) - inshuro nyinshi kurwanya ruswa ya electro-galvanizing mubwinshi bumwe.

2. Ibyingenzi Byihuta: Hex Bolt muguhuza

Hex bolt ikorana nutubuto (cyangwa umwobo wafashwe) kugirango uhambire ibice bibiri cyangwa byinshi hamwe. Ubunyangamugayo buhuriweho biterwa na preload (clamp umutwaro) yatangijwe mugihe cyo gukomera, igenzurwa nibisabwa torque, Urudodo Umwanya, na coefficient (μ) hagati yuburinganire bwimitwe hamwe nududodo. Mumateraniro igenzurwa na torque, injeniyeri bahindura intego preload mubiciro bya torque bakoresheje ibinyomoro (K ≈ 0.12–0.16 kubisiga amavuta ya zinc-flake yometseho).

Ibice bisanzwe byo gushyingiranwa mu nteko ihindagurika harimo:

Hex bolts / hex cap screw- urudodo rwuzuye (DIN 933 / ISO 4017) cyangwa urudodo rwigice (DIN 931 / ISO 4014), icyiciro cyumutungo 8.8, 10.9, cyangwa 12.9;
Hex nuts- ISO 4032 isanzwe cyangwa ISO 4033 yoroheje / jam nuts, icyiciro gihuye na bolt;
Gukaraba neza(DIN 125) na abamesa isoko (DIN 127) - gukwirakwiza umutwaro wo gutwara no kongeramo imbaraga zo kunyeganyega;
Kwiga hamwe ninkoni- kubijyanye no guhuza hamwe no guterana-guterana;
Imbuto za flange na bolts- hamwe na flanges yuzuye yibikoresho byoroshye.

Buri kimwe muri ibyo bice kigomba gusangira sisitemu imwe yo kurinda ruswa; Bolt ya Dacromet ihujwe nimbuto isanzwe ya zinc ikora a couple ya galvanic kibanza gutamba ibinyomoro.

3. Kurwanya Ruswa: Dacromet na Bolt Irangiza

Kwihangana kwumunyu (ISO 9227 / ASTM B117, amasaha kugeza ingese zitukura) nicyo gipimo cyinganda zo kurinda ruswa vuba.

Kurangiza / gutwikira sisitemu	Umubyimba	Amasaha yo gutukura (NSS)	Ingese yera (NSS)	Hydrogen	Inyandiko
Ikibaya (kwishushanya, gusiga amavuta)	—	<24h	—	Nta na kimwe	Gukoresha mu nzu gusa
Isahani ya Zinc, chromate yubururu (Zn3)	5 mm	≈ 48 h	12-24 h	Hejuru	Igiciro gito, ibicuruzwa byabaguzi
Isahani ya Zinc, passivate yuzuye (Zn12)	12 mm	≈ 192 h	96-168 h	Hejuru	Ntabwo ari ibyiciro ≥ 10.9
Gukoresha imashini	20-50 mm	300-800 h	200-400 h	Hasi cyane	Nibyiza kubice binini
Ashyushye cyane (HDG)	45-85 mm	500-100 h	200-500 h	Hasi	Imitwe ikeneye kongera gukanda
Dacromet Icyiciro cya 2	8 mm	20 720 h	300-500 h	Nta na kimwe	Nka-gukata urudodo neza
Dacromet Icyiciro cya 3 / umukara	10-12 mm	≈ 1.000 h	500-720 h	Nta na kimwe	Ibipimo byimodoka OEM

Dacromet nayo iruta zinc isa muri Ikizamini cya Kesternich (SO₂ ruswa, ISO 6988 - ikirere cyinganda nimvura ya aside), muri ibizamini bya ruswa (CCT: guhuza umunyu spray / ubuhehere / gukama), muri guhuza galvanic hamwe na aluminiyumu (dukesha aluminium flake), muri gusiganwa ku magare . imiti irwanya imiti kumunyu wo mumuhanda hamwe na de-icing imiti.

4. Umwanzuro

Kuri hex bolts hamwe nibikoresho byabo byo gushyingiranwa, Ipitingi ya Dacromet itanga uburinganire bwiza bwo kurinda ruswa, gutondeka neza, hamwe no kwizerwa kwiteraniro biboneka uyumunsi: kwihanganira gutera umunyu kugeza kumasaha 1.000, ubudahangarwa bwo kwinjiza hydrogène, kubika urudodo rwa geometrie, hamwe no guterana gushikamye kubiterane bigenzurwa na torque. Ahantu hose hahindutse hagomba kubaho imvura, umunyu, nigihe, ibisobanuro byo kwibuka ni: imbaraga-ndende hex bolt, zinc-flake (Dacromet) yometseho, ISO 10683 / ASTM F1136 yujuje.

Ntugire. Ibikurikira.
