Intangiriro kuri Dacromet Hexagonal Bolts

2026-09-09

1. Intangiriro

Mubuhanga bugezweho nubukorikori, kwizerwa kwimashini akenshi biterwa nubwiza nigihe kirekire byiziritse. Muburyo butandukanye bwo kuvura buboneka kumashanyarazi, icyuma cya Dacromet cyagaragaye nkikoranabuhanga rikomeye mugutanga ruswa idasanzwe bitabangamiye imbaraga za mashini. Dacromet ya hexagonal bolts - imitwe ya hexagon ivuwe hamwe niyi feza ya zinc-aluminium ya flake - isobanurwa cyane mu nganda aho gukora igihe kirekire mu bihe bibi by’ibidukikije ari ngombwa.

Iyi ngingo itanga incamake yuzuye ya Dacromet ya mpande esheshatu, ikubiyemo imiterere yikoranabuhanga rya coating, inzira yo gukora, ibyiza byingenzi byo gukora, kugereranya nimyenda gakondo, ikoreshwa mubisanzwe, hamwe ninganda zinganda. Gusobanukirwa nibi bintu bifasha injeniyeri, abaguzi, hamwe ninzobere mu kubungabunga gufata ibyemezo byuzuye mugihe uhitamo ibifunga kubisabwa bikomeye.

2. Gutwika Dacromet ni iki?

Dacromet (ikirango cyanditswemo cyahindutse ibisobanuro rusange byikoranabuhanga) ni sisitemu idafite amashanyarazi, idafite ingufu za zinc-flake. Igizwe ahanini na ultra-nziza zinc na aluminiyumu ikwirakwizwa mumazi ashingiye kumazi arimo chromium. Nyuma yo kuyikoresha no gukira, flake ikora urwego rwinshi rwa lamellar itanga inzitizi ndetse nigitambo (cathodic) kurinda ibyuma byubatswe munsi.

Bitandukanye na electroplating isanzwe cyangwa hot-dip galvanizing, inzira ya Dacromet ntabwo ikubiyemo gufata aside cyangwa gushira electrolytike. Ahubwo, ibice bisanzwe bisukurwa muburyo bwa mashini, byinjizwa cyangwa bigaterwa kumazi yo gufunga amazi (bikunze gukoreshwa uburyo bwo kwibiza), hanyuma bigakira hafi 300 ° C. Mugihe cyo gukira, binder ikora matrike yuzuye ya organic organique ifunga ibyuma byuma kandi bigahuza neza nicyuma fatizo.

Filime yavuyemo ni ntoya cyane - mubisanzwe ni 4-8 mm (micrometero) - itanga imbaraga zo kurwanya ruswa inshuro nyinshi kuruta ibisanzwe bya zinc bitwikiriye cyangwa binini cyane. Kugaragara kurangiye mubisanzwe ni icyuma kimwe cya silver-imvi. Impinduka zigezweho, zirimo chrome yagabanijwe hamwe na sisitemu idafite chrome (nka Geomet), ikemura amategeko agenga ibidukikije bigenda bihindagurika mugihe hagumijwe inyungu zingenzi zikorwa.

3. Bolt ya mpande esheshatu n'uruhare rwo kuvura ubuso

Hexagonal bolts (nanone yitwa hex head bolts cyangwa hexagon head screw) iranga umutwe wimpande esheshatu zituma urumuri runini rushyirwa hamwe nibisanzwe cyangwa socket. Biri mubintu bisanzwe bifatirwa mugukoresha, ibinyabiziga, imashini, hamwe nubwubatsi. Impamyabumenyi itangirira ku mbaraga nke (urugero, ibyiciro byumutungo 4.8) kugeza imbaraga nyinshi (8.8, 10.9, 12.9 na nyuma yayo), bikozwe mubyuma bya karubone cyangwa ibyuma bivangavanze hamwe nubushyuhe buvurwa kugirango bigere kumiterere yubukanishi bukenewe.

Kuvura hejuru birahambaye kuko ibyuma byambaye ubusa birashobora kwangirika, bishobora kugabanya ubushobozi bwo gutwara imizigo, gufata insinga, hanyuma bikaviramo kunanirwa hamwe. Amahitamo gakondo nka electro-galvanizing na hot-dip galvanizing ifite aho igarukira bizwi: ibyago byo kwinjiza hydrogène mubyuma bikomeye, ubuzima bwangirika bworoheje mubidukikije bikaze, hamwe no kwivanga kwinshi guterwa no gutwikira umubyimba ku nsanganyamatsiko nziza. Igikoresho cya Dacromet cyakozwe kugirango tuneshe izo nenge.

4. Ibyiza byingenzi bya Dacromet Hexagonal Bolts

4.1 Kurwanya Ruswa Kuruta

Nubwo umubyimba ufite uburebure bwa mm 4-8 gusa, Dacromet itanga uburinzi bwangirika bukubye inshuro 7-10 kurenza amashanyarazi asanzwe. Mu gupima umunyu utagira aho ubogamiye (ASTM B117 / ISO 9227), ushyizwe neza neza Dacromet ikunze kurenza amasaha 1.000 - kandi akenshi igera kumasaha 1.200 cyangwa arenga - nta bigaragaramo ingese zitukura. Sisitemu zimwe-zikora cyane zigera no kumara igihe kirekire. Uku kuramba kudasanzwe guturuka kuri barrière-barrière yuzuye ya zinc na aluminiyumu ifatanije ningaruka ya passivatif ya bordorganic binder.

4.2 Kubura Hydrogene

Kimwe mu byiza byingenzi kubifata imbaraga nyinshi ni ukubura burundu ibyago byo kwinjiza hydrogène. Inzira gakondo ya electroplating ikubiyemo gusukura aside hamwe no guterwa catodiki, byombi bishobora kwinjiza hydrogène ya atome mumashanyarazi. Iyi hydrogène irashobora gutera kuvunika gutinda kumeneka cyane - cyane cyane mubyiciro byumutungo 10.9, 12.9 no hejuru. Kuberako inzira ya Dacromet idakoresha aside irike cyangwa electrolysis, imbaraga zikomeye zirashobora gutwikirwa neza mugihe zigumana ubunyangamugayo bwuzuye.

4.3 Kurwanya Ubushyuhe buhebuje

Ipasitike ya Dacromet ikomeza kuba nziza kandi ikingira ubushyuhe bwa serivisi ikomeza kugera kuri 300 ° C (no guhura nigihe gito ndetse no hejuru). Amashanyarazi asanzwe ya zinc atangira kwangirika no gutakaza imbaraga zo kwangirika munsi ya 100-150 ° C. Ihungabana ryumuriro rituma Dacromet ya hexagonal ihinduranya neza kubice bya moteri, sisitemu yo gusohora, itanura ryinganda, nibindi bidukikije byashyizwe hejuru.

4.4 Filime Ntoya hamwe nu murongo uhuza

Ipfunyika yoroheje, imwe irinda urwego rukomeye hamwe no kwihanganira. Bitandukanye na galvanizing ishyushye, ibika 50-80 mkm cyangwa irenga kandi akenshi bisaba ubunini burenze urugero cyangwa nyuma yo gutwikisha umugozi wiruka, Dacromet yometseho ibishishwa irashobora guhuzwa nimbuto zisanzwe nta nkomyi. Igipfukisho kandi cyinjira mu biruhuko, insinga zimbere, hamwe na geometrike igoye guhuza isahani imwe hakoreshejwe uburyo bwa electrolytike.

4.5 Kwizirika gukomeye no gusubiranamo

Filime yakize ya Dacromet ikomera cyane kuri substrate yicyuma. Itanga kandi urufatiro rwiza rwimyenda ya topco cyangwa amarangi mugihe iyindi mabara ya code, kugenzura friction, cyangwa ibisabwa byiza. Amakoti agenzurwa-yogusebanya (nka sisitemu ya Dacrolub cyangwa Plus) akoreshwa kenshi kugirango agere kumubano uhoraho wumuriro mugihe cyo guterana.

4.6 Inyungu zibidukikije nibikorwa

Chimie ishingiye kumazi hamwe no gufunga-gufunga ibyara imyanda ishobora guteza akaga cyane kuruta imirongo isanzwe. Mugihe ibyakera bya Dacromet birimo chromium ya hexavalent, chromium igezweho cyangwa idafite chromium nkeya (Geomet nibindi bisa) byujuje amabwiriza akomeye y’ibidukikije nka RoHS, ELV, na REACH mugihe atanga umusaruro ugereranije.

5. Kugereranya na Coatings gakondo

Imbonerahamwe ikurikira irerekana incamake yimikorere itandukanye hagati ya Dacromet nuburyo bubiri busanzwe bwa zinc:

Umutungo	Dacromet	Amashanyarazi	Ashyushye
Ubunini	4-8 mm	5-15 mm	50-80 mm
Gusiga umunyu (nta ngese itukura)	≥1,000–1,200 h	100–300 h	500-800 h
Amashanyarazi ya hydrogen	Nta na kimwe	Ibyago byinshi	Ntibisanzwe
Kurwanya Ubushyuhe	Kugera kuri 300 ° C.	≤100 ° C.	≤200 ° C.
Ingingo Ihuza Ingaruka	Ntarengwa	Hasi	Birahambaye
Bikwiranye na HS Bolts	Cyiza	Ntarengwa	Guciriritse

Imbonerahamwe 1. Kugereranya incamake yibisanzwe bya zinc bishingiye kubifata.

7. Umwanzuro

Dacromet ya hexagonal bolts yerekana igisubizo gikuze, gikora neza cyane kubisabwa bisaba kurinda igihe kirekire kwangirika, gutuza ubushyuhe, no kubura hydrogène. Ipine yoroheje ariko ikora cyane ya flake ya zinc-aluminiyumu irenga byinshi mu mbogamizi zijyanye na electro-galvanizing isanzwe hamwe na hot-dip galvanizing, mugihe igumye ihujwe nibisabwa murwego rwo guteranya neza.

Mu gihe inganda zikomeje guharanira ko ubuzima bumara igihe kirekire, kugabanuka kubungabungwa, no kubahiriza amabwiriza akomeye y’ibidukikije, hashyizweho ingamba zo gutera imbere zinc-flake-harimo n’ibindi bigezweho bya chrome-biteganijwe kwaguka. Kuri ba injeniyeri n'abanditsi basobanura, guhitamo Dacromet-itwikiriwe na hexagonal bolts ni ingamba zagaragaye zo kuzamura kwizerana hamwe kwangirika, ubushyuhe bwinshi, cyangwa imbaraga-zikomeye zidukikije.

Mugihe hagaragajwe ibyo bifunga, hagomba kwitonderwa urwego rwo gutwikira (uburemere bwa coating), amakoti atabigenewe yo kugenzura amakimbirane, ibyiciro byumutungo shingiro, no kugenzura niba byubahirizwa n’ibipimo mpuzamahanga cyangwa abakiriya. Guhitamo neza hamwe nubuziranenge bugenzurwa neza byemeza ko ubushobozi bwuzuye bwikoranabuhanga rya Dacromet bugaragara muri serivisi.
