GEOMET® (Jumete) Yashizweho Hexagonal Bolts-Intangiriro ya Tekinike 

1. Intangiriro kuri GEOMET® (久美特) Igipfukisho

GEOMET® (bakunze kwita mu gishinwa nka 久美特 cyangwa Jumete) ni chromium idafite amazi, ishingiye ku mazi ya zinc-aluminium flake yatunganijwe na NOF Metal Coatings Group nk'umusimbura wangiza ibidukikije mubikorwa gakondo bya DACROMET®. Itanga uburinzi budasanzwe bwo kwangirika kwicyuma, cyane cyane impande esheshatu, mugihe hubahirizwa byimazeyo amategeko agenga ibidukikije nka RoHS, REACH, ELV (2000/53 / EC), na ISO 10683.

Ipitingi igizwe na zinc passivated zinc na aluminiyumu ihujwe na matrike idasanzwe. GEOMET® ikoreshwa muburyo bwa dip-spin cyangwa spray hanyuma igakira mugihe cy'ubushyuhe buke, GEOMET® ikora firime yoroheje ya silver-imvi (mubisanzwe 6-12 mm) idahindura cyane mubipimo byurudodo cyangwa bikwiye. Kuberako inzira itari electrolytike, ikuraho burundu ibyago byo kwinjiza hydrogène-inyungu yingenzi kumashanyarazi akomeye (ibyiciro byumutungo 8.8, 10.9 na 12.9).

1.1 Ibyiza byingenzi bya GEOMET®

• Chromium yuzuye (nta Cr⁶ cyangwa Cr³⁺) kandi ishingiye kumazi - gukora ibidukikije byangiza ibidukikije.
• Kurwanya umunyu mwiza-spray: amasaha 720–1500 + amasaha (ISO 9227 / ASTM B117) bitewe nurwego n'ubunini.
• Nta hydrogène yinjira - nibyiza kubifata cyane.
• Filime ntoya (≈ 8 μ m ugereranije) - ntabwo ibangamira inteko ya bolt-nut cyangwa indangagaciro za torque.
• Ubushyuhe bwiza bugera kuri 300 ° C hamwe no kurwanya ibinyabiziga bitwara ibinyabiziga, ibishishwa hamwe na ruswa.
• Amashanyarazi hamwe na bimetallic guhuza na aluminium.
• Byemejwe na OEM nini: Toyota, Honda, VW, BMW, GM, Ford, Daimler, Fiat, nibindi.

1.2 Icyiciro cya GEOMET®

Imbonerahamwe 1 - Kugereranya Sisitemu Zisanzwe za GEOMET®

Icyitonderwa: Imikorere nyayo iterwa nuburemere bwo gutwikira (mubisanzwe> 24 g / m²), gutegura substrate, hamwe namakoti ya PLUS® atabishaka bikomeza guhindura coefficient (μ ≈ 0.06–0.20 kuri ISO 16047).

2. Impande esheshatu - Igishushanyo nubuziranenge

Hexagonal (hex) umutwe wumutwe uri mubintu bikoreshwa cyane. Umutwe wabo wimpande esheshatu zituma kworoha byoroshye hamwe nudusanduku dusanzwe cyangwa socket kandi bitanga ubuso bunini. Iyo uhujwe na GEOMET® itwikiriye, ibi byuma bitanga imbaraga zumukanishi mwinshi hamwe nigihe kirekire cyo kurwanya ruswa.

2.1 Ibipimo mpuzamahanga bijyanye

• ISO 4014 / DIN 931 - Hexagon umutwe uhinduranya umugozi wigice (shank munsi yumutwe).
• ISO 4017 / DIN 933 - Hexagon imitwe yimitwe yuzuye.
• ISO 898-1 - Ibikoresho bya mashini bifata ibyuma bikozwe mubyuma bya karubone nicyuma kivanze (ibyiciro byumutungo 4.6 kugeza 12.9).
• ISO 10683 - Gukoresha amashanyarazi ya zinc flake yometse kuri feri (ikoreshwa kuri GEOMET®).
• ASTM F1136 / F1136M - Zinc / Aluminium Yangirika Kurinda Ibifunga.

2.2 Ibyiciro byumutungo wa mashini (ISO 898-1)

Imbonerahamwe 2 - Ibyiciro byumutungo rusange kuri Steel Hex Bolts

Gupfundikanya GEOMET® bifite agaciro cyane cyane mubyiciro 10.9 na 12.9 kuko inzira itari electrolytique irinda kwinjiza hydrogène ishobora kubaho hamwe na electro-galvanizing isanzwe.

2.3 Ibipimo bisanzwe

Ibipimo bya mpande esheshatu bitangwa mubipimo kuva kuri M5 kugeza M36 (kandi binini kubisabwa). Ikibanza cyumutwe gikurikira ISO metric coarse ikurikirana. Igice-cyumutwe (ISO 4014) usige shanki idasomwe itezimbere imbaraga zogosha; Bolt-yuzuye-bolts (ISO 4017) yerekana uruhare runini mu mwobo wafashwe.

3. Imikorere Data & Coating Ibiranga

3.1 Amakuru yo Kurwanya Ruswa

Imbonerahamwe 3 - Imikorere isanzwe idafite aho ibogamiye (NSS) Imikorere (ISO 9227 / ASTM B117)

Ibizamini bya ruswa byangirika (urugero, GMW 14872, SAE J2334, ACT) nabyo byerekana ibisubizo byiza-mubisanzwe inzinguzingo 60 cyangwa zirenga nta ngese itukura iyo ikoreshejwe neza.

3.2 Ibintu byiyongera kumikorere

1. Kurwanya ubushyuhe: Imikorere yagumanye nyuma ya 100 h kuri 180 ° C; ikoreshwa kugeza kuri ≈ 300 ° C mugihe gito.
2. Kurwanya imiti: Kurwanya neza ibicanwa, amavuta, amazi ya feri, ibicurane hamwe nudukoko twinshi (VDA 621-412).
3. Kuramba kwa mashini: Kurwanya bihebuje gukemura ibyangiritse no kuzunguruka kwinshi mugihe amakoti yamavuta yakoreshejwe.
4. Irangi: Bihujwe nuburinganire bwinshi hamwe nifu ya poro.

3.3 Kugereranya nubundi buryo bwo gutwikira

Imbonerahamwe 4 - GEOMET® nubundi Bisanzwe Byihuta

4. Gusaba no Guhitamo Amabwiriza

GEOMET® itwikiriwe na mpande esheshatu zigaragara cyane mu nganda aho kurinda ruswa igihe kirekire, kubahiriza ibidukikije ndetse n’imikorere yizewe isabwa icyarimwe.

4.1

• Imodoka: chassis, guhagarikwa, powertrain, kwizirika munsi yumubiri (byemejwe na VW, BMW, GM, Toyota, Honda, nibindi).
• Ubwubatsi & ibikorwa remezo: ibyuma, ibiraro, gari ya moshi, iminara ya turbine.
• Imashini zubuhinzi nubwubatsi.
• Inzu y'amashanyarazi na elegitoronike aho bikenewe kandi birwanya ruswa.
• Ibikoresho rusange byinganda byerekanwe nubushuhe, umunyu cyangwa ubushyuhe bwa cycle.

4.2 Ibyifuzo byo gutoranya

Mugihe ugaragaza GEOMET® ya mpande esheshatu, suzuma ibi bikurikira:

1. Icyiciro cya ruswa gisabwa → hitamo GEOMET 321 (isanzwe), 500 (igenzurwa na friction) cyangwa 720 (uburinzi ntarengwa).
2. Imbaraga za mashini → hitamo ibyiciro byumutungo 8.8, 10.9 cyangwa 12.9 ukurikije imitwaro numutekano.
3. Ubwoko bwinsanganyamatsiko thread umugozi wigice (ISO 4014) kubice byogosha; insanganyamatsiko yuzuye (ISO 4017) yo gusezerana ntarengwa.
4. Coefficient de fraction → vuga ikoti ya PLUS® niba igenzurwa rya torque-tension ari ngombwa.
5. Ibidukikije & amabwiriza asabwa → GEOMET® yujuje RoHS, REACH na ELV nta musoro wongeyeho.

4.3 Inyandiko zubwishingizi bwiza

Abasaba kwifata bazwi cyane babika ibyemezo (ISO 9001) kandi akenshi bafite ibyemezo bya OEM (Toyota, GM, nibindi). Ubunini bwa coating, adhesion (test tape), imikorere yumunyu-spray hamwe na coefficient de friction igomba kugenzurwa ukurikije ISO 10683 nigishushanyo cyabakiriya. Kugaragara kugaragara ni icyuma kimwe cya silver-imvi; ibara ryirabura (GEOBLACK®) naryo riraboneka mugihe ubwiza cyangwa indangamuntu bisaba.

5. Umwanzuro

GEOMET® (久美特) itwikiriye impande esheshatu zihuza guhuza imashini zizewe za ISO-zisanzwe zifata imitwe hamwe na kijyambere, chromium idafite zinc-aluminium flake itanga uburyo bwo kurinda ruswa idasanzwe, kubahiriza ibidukikije ndetse nubwisanzure bwa hydrogène. Byaba bikoreshwa muri chassis yimodoka, ibyuma byubatswe byubatswe cyangwa imashini zinganda, ibyo bifata bitanga igisubizo gisumba tekiniki kandi kizaza-gisabwa kubisabwa.

Ushaka ibyifuzo byihariye byumushinga, ibisobanuro bifatika cyangwa amakuru yumutungo wubukanishi, baza ibipimo ngenderwaho bya ISO (4014, 4017, 898-1, 10683) hamwe nimpapuro zamakuru ya tekiniki yatanzwe na NOF Metal Coatings Group cyangwa ababisabye babiherewe uburenganzira.
