Dacromet Flange Bolts-Incamake ya tekiniki 

1. Intangiriro

Dacromet flange bolts nimbaraga zikomeye zifatanije zihuza igishushanyo mbonera cyumutwe hamwe na flake ya zinc-aluminium yateye imbere izwi nka Dacromet (nanone yitwa zinc-chromium). Flange ihuriweho munsi yumutwe ikwirakwiza imitwaro iringaniye, yongerera ubuso bwayo, itezimbere kurwanya ihindagurika ryatewe no guhindagurika, kandi akenshi bikuraho gukenera gukaraba.

Yatejwe imbere mu myaka ya za 70 nkuburyo bukomeye bwo gukoresha amashanyarazi asanzwe hamwe na kadmium, tekinoroji ya Dacromet yabaye uburyo bwo kuvura hejuru yicyiciro cya 8.8, 10.9 na 12.9. Ibi bifunga bikoreshwa cyane mumashanyarazi ya chassis hamwe na powertrain, ibyuma byubaka umuyaga, imashini zubuhinzi nubwubatsi, ibikoresho byo gutunganya imiti, ibikoresho byo mu nyanja hamwe n’ibikorwa remezo byo hanze aho kurwanya ruswa igihe kirekire ari ngombwa.

Igicapo A. Kugereranya isura ya Dacromet ikozweho hex flange bolts (metallic silver-gray finish).

2. Gutwika Dacromet ni iki?

Dacromet ni amashanyarazi adafite amashanyarazi, ashingiye ku mazi adafite umubiri ugizwe na zinc flake, flake ya aluminiyumu hamwe n’ibintu bya chromium (cyangwa imashini zigezweho za chromium) zikwirakwizwa muri matrise yihariye. Ipitingi ikoreshwa hakoreshejwe uburyo bwa dip-spin, spray cyangwa uburyo bwo gukuramo amazi hanyuma igakira neza kuri 300-320 ° C. Mugihe cyo gukiza ibintu byinshi, ibyiciro byinshi bya lamellar bishyirwaho icyarimwe bitanga kurinda inzitizi no kurinda ibitambo (cathodic) kurinda ibyuma byubutaka.

Ubusanzwe bwumye-firime yuburebure buri hagati ya 5 na 12 mm. Nubwo yoroheje, igifuniko gisanzwe gitanga amasaha 1.000 (mubisanzwe amasaha 1.200-2000 ya sisitemu yogukoresha neza) yo gukingira mugupima umunyu utabogamye (ASTM B117 / ISO 9227) mbere yuko hagaragara ingese zitukura - hafi inshuro 7 kugeza ku 10 imikorere ya electro-galvanizing yubunini bugereranije.

3. Ibyiza byingenzi

• Kurwanya ruswa idasanzwe: ≥1,000–1,500 h gutera umunyu bisanzwe; imikorere-yimikorere irenze 2000 h.
• Impanuka ya Zeru Hydrogen: Inzira ntikoresha aside cyangwa electrolysis, ituma iba ifite umutekano muke (Grade 10.9+).
• Ubushobozi bwo hejuru-Ubushyuhe: Imikorere yo gukingira igumana hafi 300 ° C.
• Igenzura ryiza cyane: Filime ntoya irinda urudodo geometrie; ntagikenewe kubuto bunini.
• Inyungu zo gushushanya Flange: Ndetse no gukwirakwiza imizigo, kugabanya umuvuduko wubutaka no kunoza ihindagurika.
• Umwirondoro mwiza wibidukikije: Chimie ishingiye kumazi hamwe no gufunga-kugabanya no kugabanya imigezi.

5. Gukora & Gutunganya

Inzira isanzwe ikurikirana igizwe: gusukura alkaline no gutesha agaciro; kumanura imashini cyangwa guturika (gufata aside irinda nkana); ikoreshwa rya zinc-flake slurry ukoresheje dip-spin cyangwa spray; gukiza ubushyuhe kuri 300–320 ° C; guhitamo kubushake bwamavuta cyangwa kurinda topcoat; no gukonjesha kwa nyuma wongeyeho ubugenzuzi. Porogaramu ebyiri zikurikirana zikoreshwa cyane kugirango zigere ku mubyimba usabwa no kurwego. Igenzura rikomeye ririmo isuku yubuso, ubwiza bwihuta, ibipimo bya spin, ubushyuhe bwitanura hamwe no kugenzura uburemere bwa nyuma.

6. Ibisanzwe

• Imodoka & Ubwikorezi: Chassis, guhagarikwa, moteri na feri-sisitemu ifata umunyu wo mumuhanda, ubushuhe hamwe nigare ryumuriro.
• Ingufu z'umuyaga: Umunara na fondasiyo ya turbine kumurongo no kumurongo bigomba kwihanganira imyaka myinshi ihura nikirere cyumunyu hamwe no kubungabunga bike.
• Imashini zubuhinzi nubwubatsi: Ibikoresho bikorera mubidukikije birimo ubushuhe, ifumbire, gukuramo ubutaka hamwe nikirere cyo hanze.
• Inganda zikora imiti n’inganda: Guhuza flange hamwe no gufatisha imiterere mubimera bitwara ibintu byangirika cyangwa ikirere.
• Ibikorwa Remezo & Marine: Ikiraro, iminara yoherejwe, inyubako zo ku nkombe, ibikoresho byicyambu hamwe na platifomu yo hanze.

Igishushanyo 4. Imbaraga zijyanye nibikorwa byingenzi bya Dacromet.

7. Ibipimo, amanota & Guhitamo ubuyobozi

Ibipimo ngenderwaho bikunze kuvugwa harimo DIN 6921 na ISO 4162 (hexagon flange bolts) hamwe nibipimo byigihugu bihwanye nka GB / T 5787. Ibyiciro byumutungo wimashini bikunze gutangwa na Dacromet ni 8.8, 10.9 na 12.9 ukurikije ISO 898-1. Imikorere yo gutwikira isanzwe igaragazwa haba muburemere (Grade A ≈ 24 g / m², Grade B ≈ 36 g / m²) cyangwa numubare muto wamasaha yo gutera umunyu. Imodoka nyinshi za OEM nibisobanuro byuburyo bikunda neza sisitemu ya zinc-flake kumashanyarazi akomeye cyane kuko bikuraho ingaruka za hydrogène.

Inama zifatika zo guhitamo:

1. Hitamo icyiciro cyo gukora ukurikije icyiciro giteganijwe kubora ibidukikije (ISO 9223 C3 - C5 cyangwa irenga).
2. Ku cyiciro cya 10.9 no hejuru, vuga Dacromet cyangwa igifuniko gihwanye na zinc-flake aho kuba amashanyarazi asanzwe.
3. Mugihe inteko ya torque itomoye cyangwa imikorere-yogukomeza byinshi ni ngombwa, saba ikoti ryagenzuwe-igereranya (coefficient de coiffure 0.10–0.18).
4. Koresha kandi ushyireho Bolt witonze kugirango wirinde kwangirika kwa firime ugereranije byoroshye.

8. Umwanzuro

Dacromet flange bolts itanga impagarike nziza yimbaraga za mashini nyinshi, kurinda igihe kirekire kwangirika, kugereranya neza numutekano wibikorwa. Mugukuraho ibyago byo kwinjiza hydrogène no gutanga ubuzima bwimyaka myinshi ndetse no mubidukikije bikaze, bigabanya amafaranga yo kubungabunga no kongera ubwizerwe bwimiterere murwego rwimodoka, ingufu zishobora kongera ingufu, inganda nibikorwa remezo. Kugaragaza neza ibyiciro byubukanishi busabwa, ibipimo ngenderwaho, icyiciro cyo gutwikira ibyiciro hamwe nibisabwa hejuru ya kote yemeza ko abizirika bazakora nkuko byateganijwe mubuzima bwabo bwa serivisi.
