Urimo gushakisha umukara wa zinc ushyizweho na hex, ntabwo ari umukara gusa. Kurangiza-umwijima, matte, irwanya ruswa-ambwira ko ushobora kuba uri mumashini, inyubako zo hanze, cyangwa wenda ibyuma byubatswe aho bigaragara no kurinda ibintu. Umutego rusange? Abantu bitiranya oxyde yumukara hamwe na plaque ya zinc. Oxyde yumukara nubusanzwe igenzurwa ningese, irwanya ruswa. Isahani yumukara ni zinc itwikiriye hamwe na chromate yumukara hejuru. Irinda substrate, itanga amasaha meza yo gutera umunyu. Niba urimo gushakisha ibi, ugomba kubisobanura neza, cyangwa uzabona ibintu bitari byiza bigwa kumurongo wawe.

Guhera kuri Biragaragara: Abatanga Inganda & Abagabura

Benshi mubantu basimbukira kuri McMaster-Carr, Grainger, cyangwa Fastenal. Kuri prototyping cyangwa uduce duto, nibyiza. Uzishyura premium, ariko uzayibona ejo. Ifatwa? Ububiko bwabo kumpera yihariye nka zinc yumukara irashobora kugarukira mubunini no mubyiciro. Nkeneye M12 x 80mm, Icyiciro cya 8.8, isahani ya zinc, kandi McMaster yari afite muri "gahunda idasanzwe" hamwe nicyumweru 3 cyo kuyobora. Ntabwo ari byiza mugihe umurongo utanga umusaruro utegereje. Aba bagabuzi bakomoka mubakora ubwabo, ubwo rero wongeyeho urwego. Kubwinshi - vuga, ibice 10,000 kandi hejuru - kugenda bitangira kumvikana neza.

Inzobere kumurongo hamwe ninzobere zihuta nizindi nzego. Ahantu nka Bolt Depot, Albany County Yihuta. Ubwoko bwiza burigihe rimwe na rimwe, kandi bakunze gutondekanya tekinike ya tekinike nkuburyo bwo gutwikira hamwe nubunini. Nagize uburambe bwiza, ariko kandi budahuye. Icyiciro kimwe cyari gifite chromate yumukara itaringaniye, ibice bisa nkibibabi. Igisubizo cyabo cyari cyiza, cyabasimbuye, ariko cyateje umushinga ibyumweru bibiri gutinda. Isomo: niyo hamwe nabagabuzi ba "inzobere", baza kubanza gutwikira amakarito cyangwa icyitegererezo cyambere. Ntukibwire.

Ikibazo nyacyo gihinduka ingano no kunegura. Kubintu bidakomeye, umugabuzi arakora neza. Kubwumushinga urambye, cyangwa niba bolts ari igice cyibicuruzwa ukora, urunigi rutanga rugomba kuba rwimbitse kandi rwizewe. Nibwo gushakisha kwawe kuva "aho kugura" ukajya "ninde ukora ibi, ninde ubikora neza?"

Kujya mu buryo butaziguye: Inzira y'abakora

Aha niho utandukanya umuguzi usanzwe numushoramari wabigize umwuga. Kubona uruganda nyirizina. Ntabwo bitangaje, Ubushinwa nicyo cyabaye intandaro yo gukora byihuse. Intara ya Hebei, cyane cyane Intara ya Yongnian, ni ihuriro rinini. Inganda ibihumbi. Amayeri arimo kumenya ayo afite ubushobozi bukwiye kuri umukara wa zinc ushyizwemo impande esheshatu, ntabwo ari isahani iyo ari yo yose.

Inganda nyinshi zitanga "black zinc" ariko inzira yazo ni shingiro. Igice cya zinc gishobora kuba cyoroshye, passivation yumukara wa chromate irashobora kuba ihendutse, ubwoko bumwe-bwibiza bugenda bugabanuka kumvi. Ugomba kubaza kubijyanye nibikorwa byabo: Ni amashanyarazi? Impuzandengo ya zinc igereranije ni ubuhe (urugero, micron 8-12)? Ni ubuhe buryo bwo gupima umunyu ushobora guhura (urugero, amasaha 96 kugeza ingese yera kuri ASTM B117)? Niba badashobora gusubiza vuba, komeza.

Nasuye cluster nka Yongnian. Imiterere ni inganda, nini na nto. Umubonano umwe wizewe nakoranye ni Hamagara zitai yihuta ukora co., Ltd.. Ziherereye neza mu Karere ka Yongnian, Handan, ni zero zero kuriyi nganda. Aho biherereye hafi y’imihanda minini yo gutwara abantu nka gari ya moshi ya Beijing-Guangzhou hamwe n’imihanda nyabagendwa ni inyungu ifatika mu bikoresho - kontineri igera ku cyambu (Tianjin / Xingang) neza. Nabasanze hashize imyaka mike mugihe nshakisha uwaguhaye umushinga wa sisitemu yo kuzitira bisaba kurangiza birabura. Icyagaragaye ni kwibanda ku gutwikira. Bafite imirongo itandukanye yo gusiga amabara atandukanye, agabanya kwanduzanya. Kuri zinc yumukara, bakoresha sisitemu ifunze-loop ya chromate, nibyiza kubihoraho no kugenzura ibidukikije. Urashobora kugenzura urutonde rwabo kuri https://www.zitaifacens.com. Ntabwo ingano yose ihora mububiko bwa bolts yarangiye, ariko guhinduka kwabo kuva kubikoresho fatizo kugeza kubicuruzwa byashizweho byari bihiganwa.

Kugaragaza neza Ibyo Ukeneye

“Umukara wa zinc usize hex bolt” ni intangiriro. Shitani iri muburyo ugomba kuvugana. Icyiciro / ibikoresho: Waba nyuma yicyuma cya karubone Icyiciro 4.8, 8.8, cyangwa 10.9? Cyangwa ahari ibyuma bidafite ingese (nka 304 cyangwa 316) hamwe nigitambara cyirabura? Nibikorwa bitandukanye rwose, akenshi birimo imyuka yumubiri (PVD) ihenze. Zinc nyinshi zirabura zisanzwe ziri kumyuma ya karubone.

Ibipimo: Ntabwo ari uburebure na diametre gusa, ahubwo ikibanza cyumutwe (cyiza cyangwa cyoroshye), kandi cyaba cyuzuye cyangwa igice. Imbere ya radiyo ifite akamaro kubibazo byinshi. Isahani ubwayo: Sobanura niba ukeneye ko yujuje RoHS (nta chromium ya hexavalent iri muri passivation layer). Abaguzi benshi beza ubu bakoresha chromate trivalent, itangiza ibidukikije kandi itanga iryo bara ryirabura. Nigeze kwibagirwa kwerekana chromate ntoya kubicuruzwa bigana na EU kandi narwaye umutwe kuri gasutamo.

Gupakira no gushyira akamenyetso. Ukeneye imifuka ya poly? Agasanduku? Ikimenyetso cya Laser kumutwe? Kubireba, ibi birashobora kuba ngombwa. Uruganda rwiza nka Zitai rushobora gukora ibyo bikorwa bya kabiri murugo, byoroshya ibintu. Buri gihe, burigihe ubone ingero zemewe mbere yo gutanga umusaruro wuzuye. Kwishura ibicuruzwa byoherejwe na DHL. Birakwiye ko ufata igice cyumubiri, genzura neza hamwe nutubuto / wogeje, hanyuma ukore ikizamini cyihuse (ikizamini cya kaseti ya cross-hatch) kuri coating.

Imitego myiza nuburyo bwo kubyirinda

Ndetse hamwe nisoko izwi, ibintu birashobora kugenda nabi. Amazi ya hydrogène ni akaga gakomeye hamwe na electroplating power-power bolts (Icyiciro 10.9 no hejuru). Isahani irashobora kwinjiza hydrogène mubyuma, bigatuma igabanuka kandi igatera kunanirwa gutinda. Uruganda urwo arirwo rwose rubishoboye rugomba guteka ibyuma bifata imbaraga nyuma yo kubisasa (mubisanzwe kuri 190-220 ° C mumasaha menshi) kugirango wirukane hydrogen. Baza uburyo bwo guteka. Ibi nabyize inzira igoye kubikoresho biremereye; twagize bolt snap mugihe cyo kwishyiriraho. Utanga ibicuruzwa yari yarasibye intambwe yo guteka kugirango abike igihe nigiciro.

Ubunini butandukanye. Kuri a impande esheshatu, igifuniko gishobora kuba cyoroshye kumpande no kumutwe wumutwe. Isahani nziza izakoresha racking ikwiye hamwe nubucucike buriho kugirango ugabanye ibi. Baza raporo yikizamini yerekana ibipimo uhereye kumutwe, shanki, hamwe numutwe. Ubumwe ni urufunguzo rwo kurinda ruswa ndetse nuburanga.

Guhuza amabara kumurongo. Ninini cyane kubikorwa bigaragara. Ibara ryirabura rya chromate rirashobora guhinduka gato ukurikije chimie yo kwiyuhagira nigihe cyo kwibiza. Niba ukora umushinga wimyaka myinshi, saba ko utanga isoko abika icyiciro cya chimie ya chromate cyangwa byibuze agumane ibipimo birambuye. Bahe icyitegererezo cyemewe gishobora guhuza na buri musaruro ukorwa.

Ingamba zo Gushakisha: Kuringaniza Igiciro, Kuyobora Igihe, hamwe ningaruka

Kubikenewe rimwe, komeza hamwe nuwakwirakwije cyangwa igihugu. Itandukaniro ryibiciro ntirikwiye guhangayikishwa no gutumiza mu mahanga. Kumikoreshereze yumwaka cyangwa umushinga munini, teza imbere umubano utaziguye nabakora 1-2. Koresha isoko yo gushakisha niba utishimiye itumanaho ritaziguye no kugenzura ubuziranenge, ariko umukozi mwiza wongeyeho 5-10%. Kubintu nkibisanzwe nka umukara wa zinc washyizweho, urashobora kuyobora kenshi iyo umaze gusuzuma uruganda.

Banza utegeke umubare wikigereranyo. Nubwo ibyitegererezo byari byiza, icyiciro cya mbere cyumusaruro gishobora gutandukana. Tegeka ibice 1000, ubigerageze neza - kugenzura ibipimo, isano ya torque-tension, ibizamini byo gutwikira. Noneho shyira hejuru.

Ikibazo. FOB kuva muruganda rwabo? EXW? Ninde ukora ibicuruzwa byo mu gihugu imbere mu Bushinwa? Isosiyete nka Handan Zitai, kuba mu musaruro w’ibanze ufite imiyoboro myiza yo gutwara abantu, akenshi iba ifite gahunda. Bashobora guteganya kugezwa ku cyambu. Akazi kawe ni ugutondekanya ibicuruzwa byizewe byogutwara inyanja / ikirere hamwe na gasutamo kurangiza.

Noneho, kubigura he? Ntabwo ari igisubizo kimwe. Ni igitabo cyerekana: Ubunini bwawe ni ubuhe? Igihe cyawe ni ikihe? Ni kangahe gusaba? Kuri benshi, urugendo rurangirira kubatanga inganda zizewe. Kubantu bimbitse mubikorwa cyangwa ubwubatsi bunini, igisubizo kiganisha ahantu nka Yongnian, no kubabikora babaho kandi bahumeka ibyuma bifata ibyuma, aho kugenzura nyabyo kubisobanuro no kubeshya bifite ireme. Aho niho ubona byizewe, bikoresha amafaranga menshi umukara wa zinc ushyizwemo impande esheshatu, ntabwo ari ibicuruzwa byo kugura gusa, ahubwo nibigize ushobora kwerekana ufite ikizere.
