Dacromet Flange Bolts: Intangiriro Yuzuye Kumikorere Yinshi-Ruswa-Kurwanya-Kwizirika.

2026-09-14

1. Intangiriro

Mubuhanga bugezweho nubukorikori, kwizerwa kwingingo zingirakamaro ningirakamaro muburinganire bwimiterere, umutekano, no gukora igihe kirekire. Gufata gakondo bikunze kurwara ruswa, cyane cyane ahantu habi harimo ubushuhe, umunyu, imiti, cyangwa ubushyuhe bwinshi. Dacromet flange bolts ikemura ibyo bibazo muguhuza flake yihariye ya zinc-aluminium hamwe nibyiza bya tekinike yo gushushanya umutwe wa flange.

Dacromet flange bolt nigikorwa cyihuta cyane gihuza ibyuma byubatswe bisa nkibikoresho byogejwe munsi yumutwe hamwe na cinc-flake itari electrolytike izwi nka Dacromet (cyangwa sisitemu yo gutwikira zinc flake ikomokaho). Ihuriro ritanga imbaraga zidasanzwe zo kurwanya ruswa, imbaraga zidahwema gukomera, hamwe nubwisanzure bwo kwinjiza hydrogène - bigatuma bikenerwa cyane cyane nimbaraga zikoreshwa cyane mumodoka, ubwubatsi, inyanja, ingufu, ninganda.

2. Gutwika Dacromet ni iki?

Dacromet ni sisitemu ishingiye kumazi, sisitemu ya zinc-aluminium ya flake ya coating yatunganijwe bwa mbere mu myaka ya za 70. Igizwe na flake ya zinc na aluminiyumu ihagarikwa muri chromate (cyangwa chromium idafite). Igipfundikizo gikoreshwa muburyo bwo kwibiza, gutera, cyangwa kwibiza hanyuma bigakizwa mubushyuhe bwo hejuru (mubisanzwe hafi 300 ° C), bigakora firime yoroheje, yuzuye, yuzuye ibice byinshi.

Ibintu by'ingenzi biranga igifuniko harimo:

Ubunini bwa firime: Mubisanzwe 4-12 mm (mubisanzwe 6-8 mm), ikomeza kwihanganira insanganyamatsiko.

Inzitizi + kurinda ibitambo: Gufunga ibyuma byuzuye bitera inzitizi yumubiri mugihe zinc itanga uburinzi bwa galvanic (ibitambo).

Nta hydrogène yinjira: Inzira idafite amashanyarazi irinda gufata aside hamwe na electrolysis, bikuraho ibyago byo gutinda kwa hydrogène gutinda kuvunika mubyuma bikomeye.

Kurwanya ubushyuhe: Hagarara hafi ya 300 ° C ikomeza ubushyuhe bwa serivisi.

Kugaragara: Icyuma cya silver-gray matte kurangiza.

Menya ko "Dacromet" nizina ryubucuruzi; sisitemu isa na zinc-flake (nka Geomet, idafite chromium) ikoreshwa cyane uyumunsi kugirango yubahirize amabwiriza agezweho y’ibidukikije (RoHS, REACH, ELV).

3. Flange Bolts ni iki?

Ikibaho cya flange (nanone cyitwa flanged hex head bolt cyangwa frame bolt) kirimo uruziga ruzengurutse munsi yumutwe wa mpande esheshatu zikora nkuwiyuhagira. Igishushanyo gikwirakwiza umutwaro ufashe hejuru yubuso bunini, bigabanya ibyago byo kwinjiza mubintu byahujwe, bigateza imbere kurwanya ihindagurika ryinyeganyeza, kandi akenshi bikuraho gukenera gukaraba.

Ubwoko busanzwe burimo:

Hex flange bolts (ibisanzwe)

Seriveri ya flange (hamwe na seriveri munsi yumutwe wa anti-rotation)

Sock umutwe cyangwa ubundi buryo bwihariye bwa flange

Iyo uhujwe na Dacromet coating, ibi byuma bitanga imikorere isumba iyindi mashini hamwe nigihe kirekire cyibidukikije.

4. Kugereranya hamwe na Coatings

Imbonerahamwe ikurikira irerekana muri make itandukaniro ryimikorere itandukanye:

Umutungo	Dacromet	Electro-Zinc	Ashyushye-Galv.	Ingese
Gusiga umunyu (amasaha)	1.000.500 +	100–300	500–1,000 +	Umurage
Ubunini	4-12 mm	5-15 mm	40–100 + mm	N / A.
H Ingaruka zo Kwinjira	Nta na kimwe	Hejuru (kuri ≥10.9)	Hagati	Nta na kimwe
Ikigereranyo Cyiza Cyiza.	~ 300 ° C.	~ 100–120 ° C.	~ 200 ° C.	Hejuru
Ingingo Ihuza Ingaruka	Ntarengwa	Hasi	Birahambaye	Nta na kimwe

Icyitonderwa: Imikorere nyayo iratandukanye nicyiciro cyo gutwikira, ubunini, ikoti hejuru, hamwe nibidukikije. Sisitemu idafite Chromium idafite zinc-flake (urugero, Geomet) itanga uburinzi busa mugihe cyujuje ubuziranenge bwibidukikije.

5. Ibice byingenzi byo gusaba

Dacromet flange bolts ikoreshwa cyane mubice bya chassis, sisitemu yo guhagarika, moteri ya moteri, guteranya feri, sisitemu yo gusohora, hamwe nimiterere yumubiri. Bihanganira imyunyu yo mumuhanda, gusiganwa ku magare yumuriro, kunyeganyega, hamwe nubushyuhe bwo hejuru butari munsi ya hood mugihe batanga umutwaro wizewe.

Mu biraro, iminara yohereza, ibyuma, hamwe n’ibikoresho byo ku nkombe, ibyo byuma bitanga uburinzi burambye bwo kwangirika kwikirere no kugabanya inshuro zo kubungabunga.

Urufatiro rwumuyaga wa turbine kumurongo, sisitemu yo gushiraho izuba, kubaka ubwato, nibikoresho byicyambu byungukirwa no kurwanya umunyu mwinshi hamwe nubushobozi bwo gutwikira geometrike imwe.

Ibikoresho byugarije ifumbire, imiti, ubushuhe, hamwe na abrasion - nk'imashini zikoreshwa mu buhinzi, pompe, indangagaciro, hamwe n’ibikoresho bitunganyirizwa - bikunze kwerekana ibyuma bifata ibyuma bya Dacromet bifatanyirizwa mu gihe kirekire cyo gukora.

6. Ibyiciro rusange, Ibipimo, hamwe nubuyobozi bwo gutoranya

Ibyiciro byumutungo: Dacromet flange bolts iraboneka mubyiciro byumutungo 4.8, 8.8, 10.9, na 12.9 (metric), kimwe nicyiciro cya 5 nicyiciro cya 8 (imperial). Impamyabumenyi ikomeye (10.9 / 12.9) yunguka cyane cyane kubura ingaruka za hydrogène.

Ibipimo by'ibipimo: Ibisanzwe bikunze kugaragara harimo ISO metric flange bolt ibipimo, DIN, GB (Igishinwa), na ASME / ANSI kumurongo wa santimetero.

Ibisobanuro byihariye: Imikorere ikunze kugaragazwa nuburemere buke (urugero, Icyiciro A ≈ 24 g / m², Icyiciro B ≈ 36 g / m²) hamwe nibisabwa-gutera umunyu. Topcoats irashobora kongerwamo amavuta meza, ibara, cyangwa kurinda inzitizi.

Inama zo guhitamo: Huza sisitemu yo gutwikira icyiciro cyangirika cyibidukikije (urugero, C3 - C5 kuri ISO 12944). Kubintu bikomeye-byubatswe byubaka, wemeze amakuru ya torque-tension hamwe na coating yihariye na topcoat. Hitamo sisitemu idafite chromium mugihe bikenewe kubahiriza ibidukikije.

7. Kwishyiriraho no gutekereza kubikorwa

Koresha witonze: Nubwo igifuniko gifatanye neza, irinde kwangirika gukomeye mugihe cyo gutunganya no gushiraho.

Igenzura rya Torque: Koresha coefficient zo guterana zitangwa nuwatanze ibicuruzwa. Sisitemu ya Dacromet yamavuta itanga ibintu byinshi bya clamp imitwaro irenze amavuta ya zinc.

Guhuza: Dacromet muri rusange ihuza nibikoresho byinshi hamwe nibikoresho bifunga kandi birashobora gusiga irangi birenze iyo bikenewe.

Ubugenzuzi: Ubugenzuzi bugaragara bwo gutwikira no kugerageza (aho byerekanwe) bigomba kuba igice cyo kugenzura ubuziranenge.

8. Umwanzuro

Dacromet flange bolts yerekana igisubizo gikuze, cyihuse-cyihuse cyo gukemura neza kuringaniza neza kurinda ruswa, kwizerwa kwa mashini, hamwe nibisobanuro byuzuye. Mugukuraho ingaruka ziterwa na hydrogène mugihe zitanga imikorere yumunyu-spray urenze kure isahani isanzwe ya zinc, babaye amahitamo meza yo gusaba ibisabwa mumodoka, ingufu, ubwubatsi, ninganda.

Mugihe amabwiriza y’ibidukikije akomeje guteza imbere ikoreshwa rya sisitemu ya chromium idafite zinc-flake, ikoranabuhanga rikomeje gutera imbere mu gihe rigumana ibyiza byaryo. Mugihe hagaragajwe ibyuma byangiza cyangwa ubushyuhe bwo hejuru-cyane cyane aho hasabwa amanota menshi-Dacromet (cyangwa ihwanye na zinc-flake ihwanye na flake) igomba gufatwa nkigisubizo cyemejwe kandi gihenze mubuzima bwinteko.

Ba injeniyeri n'abaguzi barashishikarizwa kugisha inama abatanga ibicuruzwa kugirango babone impapuro zirambuye za tekiniki, coefficient zo guterana, hamwe na raporo y'ibizamini byumunyu-spre yihariye ya sisitemu yahisemo nibisabwa.

Ntugire. Ibikurikira.
