Urumva 'electro-galvanised' ugatekereza 'kurinda ruswa,' wenda ndetse 'icyatsi' kuko ari zinc, sibyo? Aho niho ikiganiro gikunze gutangirira, kandi akenshi kirangirira. Ariko baza umuntu wese wagombaga kwerekana ibifunga kumiterere yo hanze ibona umunyu wo mumuhanda, cyangwa kubikoresho mububiko butose, maze ikiganiro nyacyo kiratangira. Ese amashanyarazi ya elegitoronike ni amahitamo arambye mubikorwa byinganda, cyangwa turimo gutsimbarara kubikorwa bisanzwe, bihendutse mugihe twirengagije ibiciro byubuzima? Njye maze imyaka nshakisha kandi ngerageza ibi bintu, kandi igisubizo ntabwo kiri murupapuro rwihariye. Ari mumurongo wa rust kumurongo nyuma y'amezi 18, ikiguzi cyo gusimbuza bolts igihumbi kuri sisitemu ya convoyeur, hamwe no guceceka gutuje bamwe mubatanga.

Allure hamwe nukuri guhita

Reka tubyumve neza: amashanyarazi ya elegitoronike afite umwanya wabyo. Inzira iroroshye - isahani ya zinc ikoresheje electrodeposition. Birahenze cyane kubikorwa byinshi. Imbere, yumye, cyangwa aho igifuniko kirenze kugaragara kimwe no kurinda byoroheje, birakora. Nategetse toni zazo ahantu nka Akarere ka Yongnian muri Hebei, umutangito winganda zihuta. Isosiyete iri hanze, Hamagara zitai yihuta ukora co., Ltd., hamwe shingiro ryiburyo ninzira nini zitwara abantu (reba urubuga rwabo kuri https://www.zitaifacens.com niba ushaka kumva igipimo), urashobora kuzenguruka ukoresheje umutwaro wa kontineri. Ibyoroshye ntawahakana.

Ariko igenzura ryambere ryukuri ni ubugari. Igikoresho gisanzwe cya electro-galvanised gishobora kuba microne 5-8. Ibyo biroroshye. Urashobora kwambara hafi ukoresheje urutoki niba ugerageza. Gereranya ibyo na hot-dip galvanizing, aho ureba microni 50+, kandi itandukaniro rirambye ntabwo ari umurongo-ni exponential. Ibi nabyize kare, ngaragaza amashanyarazi ya M12 ya elegitoronike ya kabili ya tray tray mu ruganda rutose. Mu myaka ibiri, twagize ingese yera na rust itukura kare kumuzi. Ntabwo ari ibyago, ariko kubabara umutwe ntitwari twateganije.

Ikibazo kirambye gitangirira hano: niba ibicuruzwa binaniwe byihuse kandi bikeneye gusimburwa vuba, kuzigama umutungo wambere (zinc nkeya, ingufu nke mubisahani) bihita byangwa numusaruro, kohereza, nogushiraho umusimbura. Urimo gucuruza hasi yimbere ya karubone ikirenge cya gishobora kuba hejuru yubuzima bwose. Nibyo kubara ntidukunze gukora kumaduka mugihe dushyizeho itegeko.

Ibiciro Byihishe: Imikorere ya ruswa hamwe nimbibi zikorwa

Aho electro-galvanizing yerekana imipaka yayo iri mubidukikije byose hamwe na chloride, acide, cyangwa ubuhehere buhoraho. Ipitingi ya zinc nigitambo, nibyiza, ariko biroroshye cyane bigabanuka vuba. Ndibuka umushinga urimo guhuza imiyoboro ihanamye yinyanja. Twakoresheje ASTM F1941 ifata amashanyarazi, twibwira ko byaba byiza. Gutera umunyu byihutishije kwangirika, kandi zinc yagiye mumwanya mumezi, biganisha kuri bimetallic kwangirika hamwe nicyuma kiri munsi. Ibisanzwe, birindwa kunanirwa.

Ikindi kibazo gikunze kwirengagizwa ni hydrogène embrittlement. Inzira ya electroplating irashobora kwinjiza hydrogene mubyuma bikomeye (Icyiciro cya 8.8 no hejuru), bigatuma igabanuka kandi ikunda kuvunika gitunguranye. Ibi ntabwo ari ingaruka zifatika. Nabonye bolts ifata mugihe cya torque-up, kandi mugihe guteka bishobora kugabanya hydrogène, ni intambwe yinyongera yongerera ibiciro kandi bigoye, kandi ntabwo buri gihe bikorwa byizewe kubiciro bidahenze, binini cyane. Rero, urashobora gucuruza ruswa ikingira ibyago byubukanishi. Ntabwo ari ikintu kinini.

Noneho hariho ikibazo cyo gutwikira uburinganire. Ku bice bigoye nka bolts hamwe nududodo twimbitse, electrodeposition irashobora kutaringaniza, hasigara umuzi wurudodo-ingingo ikomeye cyane-hamwe nuburinzi buke. Nibikorwa byibanze bigarukira. Urashobora gutondekanya chromate ihinduka (ubururu, umuhondo, oxyde yumukara) kugirango wongere passivation, ariko ibyo byongeramo imiti myinshi murwego rwibikorwa. Mu buryo butunguranye, isahani yoroshye ya zinc ntabwo yoroshye cyangwa isukuye.

Gupima icyatsi muri Zinc

Abamushyigikiye berekana zinc nkibintu bisanzwe, bisubirwamo. Nukuri. Ariko inzira ya electroplating ubwayo ntabwo ari nziza. Amazi mabi ava mubwogero arimo zinc ion, acide, nindi miti. Kuvura neza ntabwo biganirwaho kugirango hubahirizwe ibidukikije. Mu turere dufite inganda zikora cyane, nka Yongnian, imicungire y’ibidukikije y’amaduka y’amasahani ni yo mbogamizi irambye. Utanga isoko nka Zitai Ihuta gukorera ku rugero birashoboka ko byashyizwe hamwe, bigezweho byo kuvura, ariko ibyo ntabwo ari garanti yisi yose. Kuramba kwa bolt bifitanye isano itaziguye no kumaduka yububiko.

Gusubiramo ni inyongera. Iyo ubuzima bwanyuma burangiye, ibyuma birasubirwamo, kandi igicucu cyoroshye cya zinc cyatakaye mugushonga, ariko ntabwo cyanduye. Nyamara, iyi nyungu yanyuma yubuzima irakomeye cyane kubice bishyushye bishyushye cyane. Kuri bolt ntoya, ingufu zongera gukoresha ikirenge cyicyuma ubwacyo kiriganje; umusanzu wa coating ni marginal. Inzira nini yo kuramba ni ukongera ubuzima bwa serivisi kugirango itinde icyo gikorwa cyo gutunganya igihe kirekire gishoboka.

Noneho, nicyatsi kirenze, tuvuge, icyuma kidafite ingese? Kubidukikije byangirika, birashoboka, ku mbaraga zitanga umusaruro (gukora ibyuma bidafite ingese ni imbaraga nyinshi). Ariko mugihe cyangirika, Bolt imwe 304 cyangwa 316 idafite ingese imara imyaka 30 birashoboka rwose ko iramba kuruta gusimbuza amashanyarazi ya elegitoronike buri myaka 5-10, ndetse no kuyitunganya. Imibare irahinduka iyo urebye ubuzima bwuzuye.

Impinduka zifatika hamwe nubwihindurize

Inganda ntizihagaze neza. Ikiganiro kigenda kiva kumurongo gusa ugana imikorere. Ndimo kubona anketi nyinshi kubijyanye no gukanika imashini (birinda kwinjiza hydrogène) cyangwa se udushya twinshi twa firime ya firime polymer utanga imbaraga zo kurwanya ruswa kuruta electro-zinc mubyimbye bisa. Abatanga isoko nziza barimo kumenyera.

Iyo uganiriye na tekinike yo kugurisha rep ku ruganda rwashizweho-kandi nagize ibi biganiro hamwe nabantu kuva mubikorwa nkibyo kuri Handan Zitai Yihuta—Ntabwo bagisunika gusa numero ya catalog. Barabaza kubyerekeye ibidukikije: Ari murugo? Imiti iyo ari yo yose? Inkombe? Bashobora kukuyobora kure yumuriro wa elegitoronike ugana hejuru ya zinc-flake yuzuye cyangwa uburyo bushyushye niba icyifuzo cyawe ari ukuramba kurenza igiciro cya mbere. Icyo ni ikimenyetso cyo gukura. Ahantu habo hashingiwe kubikorwa bivuze ko babona ibyananiranye byose hamwe nubutsinzi bitambuka, kandi ibyo bitekerezo byinjira mubyifuzo byabo.

Twagerageje guhindura umukiriya muburyo bwa Dacromet (zinc-flake) yashizwemo Bolt kuva mubisanzwe amashanyarazi ya elegitoronike kugirango akoreshe ibikoresho byubuhinzi. Igiciro cyari hejuru ya 15-20%. Imyaka ibiri irashize, amashanyarazi ya elegitoronike kumashanyarazi ashaje yerekanaga ingese kumutwe wa hex, mugihe ibishya byasaga nkibishya. Umukiriya yaretse kwinubira igiciro. Guhitamo kuramba kwabitse amafaranga mugihe kirekire wirinda igihe cyo gusimburwa. Nibyo bimenyetso bifatika.

None, Icyemezo ni iki?

Hamagara amashanyarazi ya galvaniside arambye yinganda ni mugari cyane. Ni a birambye guhitamo. Kugenzurwa, ibidukikije byiza aho kurwanya igihe kirekire kwangirika bidakomeye, bitanga impuzandengo nziza yikiguzi, imikorere, hamwe no gukoresha umutungo. Kuramba kwabo kugwiza iyo imipaka yabo yubahirijwe.

Nyamara, kugirango ukoreshe inganda rusange-akenshi bisobanura ubushuhe butandukanye, ubukonje, umwanda, cyangwa imiti iterwa na chimique - kwishingikiriza kumashanyarazi asanzwe ya elegitoronike akenshi usanga ari ubukungu bwibinyoma n'inzira idashoboka. Itera ibidukikije n'ibiciro biremereye mugihe kizaza binyuze kunanirwa imburagihe.

Uburyo burambye ni uguhuza tekinoroji yo gutwikisha cyane ibidukikije, nubwo bisaba byinshi imbere. Bisobanura kubaza ibibazo bikomeye byabatanga isoko, kureba ibirenze igiciro kuri kilo, no gusuzuma igiciro cyose cya nyirubwite. Inganda zifite amahitamo meza ubu. Kuramba ntibireba gusa ibikoresho; ni uguhitamo neza kugirango ibicuruzwa ntibikeneye kongera gukorwa vuba aha. Kandi rimwe na rimwe, bolt irambye cyane niyo utigera utekereza gusimbuza.
