Amabara ya zinc yashizwemo pin shaft iramba? 

Urabona iki kibazo kigaragara cyane muri spes na RFQs. Umuntu wese arashaka pin itoroshye kandi isa neza, akenshi yerekana amabara ya zinc isa nkaho ari kurangiza, kutagira ubwenge. Ukuri kurasobanutse neza. Iyo shitingi yubururu, umuhondo, cyangwa umukara ntabwo irangi gusa; ni chromate ihinduranya hejuru ya zinc, kandi kuramba kwayo gushingiye kubintu icumi abantu bakunze kwirengagiza. Ntabwo ari amasaha yo gutera umunyu gusa kurupapuro rwamakuru.

Ibitekerezo Byibanze: Ibara Ringana Imikorere

Benshi mubatanga amasoko, ndetse nabashakashatsi bamwe, babona ibara rirangiye. Bazasaba pin pin yubururu yibwira ko ibara ubwaryo ritanga ruswa. Ngiyo umutego wambere. Ibara ni umusaruro wibikorwa bya chromate-ubururu busanzwe bwa chromate iridescent, umukara ushobora kuba chromate yumukara, nibindi. Inkinzo nyayo nuburebure bwa zinc layer, bipimirwa muri microne, hamwe nubwiza bwa kashe ya chromate. Nabonye amapine afite ubururu bwiza, bwimbitse hue yananiwe imburagihe kuko kubitsa zinc byari bito kandi byoroshye, cyangwa koza chromate byari byanduye. Ibara ryari ryiza rwose kugeza ingese itukura irabye munsi yacyo.

Noneho hariho substrate. Kuramba kwa pin shaft itangira kera mbere yo gushiraho. Niba urimo gukora pin kuva murwego rwo hasi, insinga zanduye zifite ubusembwa bwubuso, isahani izongerera izo nenge, ntizihishe. Ibi twabyize inzira igoye mumyaka yashize kumurongo wibikoresho bya clevis kubikoresho byo hanze. Ibisobanuro byahamagariye umukara zinc kurangiza. Basaga neza cyane mu gasanduku, ariko mu gihe cy'amezi atandatu mu karere k'inyanja, basizwemo ingese zera n'ibyobo byangirika. Post-mortem yerekanaga ko ikibazo atari ubwogero bwa plaque kuri buri mwanya, ahubwo ubuziranenge bwibintu bidahuye nuwatanze insinga. Isahani yakurikiranye gusa ibyuma bya subpar.

Kugenzura inzira ni byose. Ibyiciro byogusukura mbere yo gusya - kugabanuka, gufata aside - twavuga ko ari ingenzi kuruta ikigega ubwacyo. Amavuta yose asigaye cyangwa igipimo cya oxyde irinda zinc neza. Ndibuka ko nasuye uruganda rwihuta, nka Handan Zitai Fastener Manufacturing Co., Ltd. hejuru ya Yongnian, Hebei - ako karere ni ihuriro rinini cyane. Urashobora kubona itandukaniro riri hagati yimirongo. Ibyiza byari bifite isuku ibyiciro byinshi kandi byoza neza. Imirongo ihendutse yagabanya inzinguzingo. Igisubizo? Amapine yatsinze ikizamini cyihuta cyamasaha 24 yumunyu ariko yerekana amanota yo gutsindwa nyuma yubushyuhe buke cyangwa gukuramo byoroheje.

Aho Kuramba Mubyukuri Bipimwa

Mubyukuri, isi ya pin ntabwo yicaye muri laboratoire idafite aho ibogamiye. Irimo gukemurwa, kwinjizwamo, wenda guhura nubushyamirane, guhura nimiti, cyangwa urumuri rwa UV. Kurwanya Abrasion ni nini cyane. Urwo rwego rwa chromate ni ruto, akenshi uduce duto twa micron. Niba gusaba kwawe birimo pin kunyerera no gusohoka inshuro nyinshi, ubwo buso bwamabara meza burashobora gushira vuba, bikerekana zinc yo gutamba hanyuma ibyuma byibanze. Kubihe nkibi, igicucu cyinshi cya zinc hamwe na chromate isobanutse cyangwa yumuhondo (ikunda kuba ndende cyane) irashobora kurenza chromate yumukara yoroheje, ishushanya, kabone niyo umukara ufite igipimo cyinshi cyo gutera umunyu mukigereranyo.

Imiti igaragara nubundi bwicanyi bucece. Tekereza inteko hafi y'ibice bya batiri, cyangwa mumashini zikoreshwa amavuta cyangwa ibikoresho byoza. Bamwe bakora isuku ya alkaline barashobora kwambura chromate ako kanya. Twari dufite dosiye hamwe na pin zikoreshwa mumashanyarazi yimodoka. Berekanye ubururu bwa zinc busize pin shaft kugirango birinde ruswa. Uruganda rwo guteranya rwakoresheje ikirango runaka cyogusukura inganda kumurongo wanyuma. Mugihe cibyumweru, igifuniko cyubururu cyahindutse kijimye kandi kijimye. Ikibazo cyari kidahuye na pH. Filime ya chromate ntabwo yari ihagaze muri ibyo bidukikije byimiti. Gukosora ntibyari byiza bya plaque ya zinc, ahubwo byahinduye chimie itandukanye ya chromate (passivate trivalent aho kuba hexavalent) yari inimiti yashizemo iyo miterere.

Noneho hariho hydrogène embrittlement. Kumashanyarazi akomeye cyane (hejuru ~ 40 HRC), inzira ya electroplating irashobora kwinjiza hydrogene mubyuma, bigatuma ivunika kandi ikunda kuvunika gitunguranye munsi yumutwaro. Iki ntabwo ari ikibazo cyo kwisiga; ni kunanirwa gukora. Uruganda urwo arirwo rwose ruzwi rukora imashini rukomeye rugomba gushyiramo uburyo bwo guteka nyuma yo gusya kugirango wirukane hydrogen. Yongeraho igiciro nigihe, kandi rimwe na rimwe birashimangirwa-nabaguzi batanga inguni. Buri gihe ubaze niba guteka birimo ibice-bikomeye. Ntabwo ari ibiganiro.

Urugero rwa Handan nubucuruzi bufatika

Gukorana nabakora ibicuruzwa ahantu nkakarere ka Yongnian, urabona ibicuruzwa biva mugihe nyacyo. Isosiyete nka Handan Zitai Yihuta (urashobora kubona intera yabo kuri https://www.zitaifacens.com) yashyizweho kubipimo, biherereye iburyo bukomeye bwo gutwara abantu. Ibyiza byabo birahoraho, gutunganya amajwi menshi. Kubisanzwe ibara rya zinc Porogaramu-tekereza ibikoresho byo mu nzu, guhuza imashini zidakomeye, ibikoresho bya elegitoroniki - birashobora gutanga ibicuruzwa bihendutse cyane, byiza-byiza. Kuramba bizaba byiza kubidukikije byimbere.

Ariko kubikorwa bikomeye cyangwa bikaze, ugomba kwishora cyane. Nukugaragaza ibisobanuro birambuye: uburebure bwa zinc (urugero, min 8-12μm min), ubwoko bwa chromate (urugero, chromate yumukara kubora neza gato, iridescent kubwiza bwiza), hamwe na kashe ya posita cyangwa ikoti. Nibyo, ibinyabuzima bisobanutse neza hejuru ya zinc birashobora kongera imbaraga zo gukuramo no kurwanya imiti. Yongeyeho indi ntambwe nigiciro, ariko ihindura ubuzima bwigice mumurima. Ni itandukaniro riri hagati ya pin kubikinisho byumwana na pin kubutaka bwa marine bukwiye.

Isesengura ryananiwe ni mwarimu wawe mwiza. Twigeze gushakira icyiciro cyumuhondo wa zinc ushyizwemo cotter pin kubakora ibikoresho byubuhinzi. Raporo yumurima yaje ifite ingese zikomeye nyuma yigihembwe kimwe. Isesengura rya laboratoire ryerekanye urwego rwa chromate rutaratera imbere, hafi yabuze ahantu. Umuhondo wasangaga irangi. Intandaro? Ubwogero bwa chromate bunaniwe uwabitanze yagerageje kurambura. Isomo: kwizera ariko kugenzura. Ikizamini cya gatatu-cyitegererezo ku byitegererezo biva mu bicuruzwa ni ubwishingizi buhendutse. Ntukishingikirize gusa ku cyemezo cy'urusyo.

None, Ni uwuhe mwanzuro uramba?

Nibisabwa. Byakozwe neza zinc yashizwemo pin shaft hamwe na chromate ihindagurika ikwiye iramba bihagije kumurongo munini wa porogaramu. Itanga ibitambo byiza byo kwangirika no kurwanya kwambara neza. Kurangiza amabara bitanga inzitizi yibanze ninyungu nziza. Ariko imipaka yayo irasobanutse: guhora abrasion, acide ikomeye cyangwa alkalis, ibidukikije byubushyuhe bwo hejuru, hamwe no kwibiza mumazi yumunyu bizayitsinda.

Niba ukeneye byinshi, uzamuka mukubika imashini (nziza kumiterere igoye, ibyago bike byo guterwa), cyangwa ibifuniko nka geometrike cyangwa dacromet, cyangwa amaherezo, ibyuma bitagira umwanda. Ariko kubiciro, pin ya zinc iragoye gutsinda. Urufunguzo ni ugucunga ibiteganijwe no kwerekana neza. Ntukandike zinc gusa. Kugaragaza urwego rwibikoresho fatizo, imbaraga zingana, uburebure bwa zinc ntarengwa, inzira ya chromate (urugero, ISO 4042, ASTM B633 Ubwoko bwa II), hamwe nibisabwa nyuma yubuvuzi nko guteka cyangwa gufunga.

Mu kurangiza, kuramba ntabwo ari umutungo wibara. Numutungo wurwego rwose rwo gukora - kuva muruganda rwinsinga kugeza kubumba, kuvura ubushyuhe, kubumba chimie, no kugenzura inzira. Igipapuro cyatanzwe na producer ufite disipuline hamwe nibisobanuro byoroshye birashobora kumara imyaka. Igipapuro gisa-kimwe kiva mu iduka ryoroheje ntigishobora kugerwaho mu cyi cyinshi. Itandukaniro riri mubisobanuro utigeze ubona kugeza binaniwe.
