Reka tugabanye kwirukanwa: niba utekereza ko gasketi isanzwe ya electrogalvanised ari igisubizo cyizewe cyigihe kirekire cyo gutera umunyu, gutera imiti, cyangwa ubuhehere bwinshi, birashoboka ko wishyiriyeho kunanirwa kumurima uhenze. Ikibazo nyacyo ntabwo kijyanye no gutwikira ubwacyo, ahubwo kijyanye nuburyo bwihariye bwo gutsindwa bwirengagizwa kugeza bwije.

Icyizere kidahwitse muri Micron-Ntoya

Nabibonye inshuro nyinshi. Ikirangantego guhamagarira galvanised, na electrogalvanizing ibona umutwe kuko ihendutse kandi isa neza neza mukibanza-cyiza kandi kirabagirana. Ibitekerezo ni byose ni zinc, igomba rero gutanga uburinzi busa. Ngiyo umutego wambere. Electrogalvanizing mubyukuri ni inzira ya electrolytike ibika inanutse, ndetse igaragara, mubisanzwe hafi ya microni 5-10. Nibyiza kubigaragara kandi bitanga uburinzi bwibanze bwo kwirinda kwangirika kwikirere. Ariko mubyukuri ibidukikije bibi- tekereza ku mbuga za interineti zo ku nkombe, imirongo itunganya imiti, cyangwa munsi yimashini zidafite aho zihurira - icyo cyizere kirashira vuba. Igice ni gito cyane kugirango gitange ibikorwa byinshi byo gutamba anode ibikorwa bimaze guhungabana.

Kunanirwa gake bitangira nkingese rusange. Akenshi ni igitero cyaho cyo gutera. Igishushanyo mugihe cyo kwishyiriraho, micro-crack yo kuva, cyangwa niyo mpande gusa aho igifuniko gisanzwe cyoroshye gihinduka intangiriro. Mugihe gishyushye cyane, igipfundikizo cyinshi hamwe nicyuma cya zinc alloy irashobora gukomeza kurinda ibyuma. Mu bice by'amashanyarazi, icyuho kigera ku cyuma fatizo hafi ako kanya. Kuva aho, munsi ya firime ya ruswa iranyerera, kandi zinc ntishobora kurinda igitambo ahantu hanini kuko nta misa ihagije ihari. Urangiza ufite ingese ziva mumaraso munsi ya zinc igaragara neza, ninzozi mbi yo kugenzura.

Twakoresheje ibizamini ku rundi ruhande hashize imyaka, nta nubwo ari siyansi, gusa twamanitse ingero ku ruzitiro hafi y'uruganda rutunganya amazi. Ibyitegererezo bishyushye byerekanaga ingese yera (okiside ya zinc) nyuma y'amezi 6 ariko nta ngese itukura. Uwiteka Gasketroga ingero? Batangiye kwerekana ibibara bitukura ku mwobo wa bolt no guca impande munsi yiminsi 90. Ukwezi kwa 8, ingese yariyongereye. Iyo myenda yoroheje, imwe ni umwanzi wayo - nta mubyimba wongeyeho ku mpande zoroshye.

Aho Electrogalvanized ishobora gufata (Kandi Aho itazashoboka rwose)

Ntabwo ari ibyago byose. Hano haribidukikije bigenzurwa aho electrogalvanizing ihagije kandi ihendutse. Porogaramu yo mu nzu ifite ubuhehere butajegajega, cyangwa mu nteko zifunze mu kirere (nko mu mashanyarazi amwe n'amwe afite kashe ya gaze). Urufunguzo ni ukubura ubuhehere buhoraho cyangwa imiti ikaze. Nabisobanuye kubijyanye nimiterere yimbere mububiko bwububiko, kurugero. Nibyiza.

Uturere twose ntidushobora kujya harimo chloride, inshuro nyinshi zumye-zumye, cyangwa umwotsi wa aside / alkaline. Ndibuka umushinga urimo imiyoboro mu ruganda rutunganya ibiryo hamwe na acide acide yoroheje. Injeniyeri yerekanye gasketi ya elegitoronike ya flanges zose. Basaga neza mugihe cyo kwishyiriraho. Mu gihe cy'umwaka umwe, twatembye ahantu hamwe. Igipapuro cyari cyangiritse kugeza aho gitakaza imbaraga zo gufunga no gufunga ubunyangamugayo. Igicuruzwa cyangirika (ingese) nacyo cyatwaye amajwi menshi, gishobora kongera ibitekerezo byongera umutwaro wa bolt, ariko mubyukuri, washenye gusa ibintu byangiritse. Gukosora byari kuzimya no gusimburwa na gaseke 316 idafite ibyuma - isomo ribabaza mugiciro cyose cyashyizweho.

Ikindi kintu gikunze kwirengagizwa ni guhuza galvanic. Mwembi an Gasketroga hamwe nicyuma kidafite ingese hamwe na bolt mubidukikije bitose, kandi waremye bateri. Zinc (anodic) izangirika cyane kugirango irinde ingese (cathodic). Ibi birashobora kwihutisha ikoreshwa ryurwego ruto rwa zinc ku gipimo giteye ubwoba. Muburyo nk'ubwo, ushobora kuba mwiza hamwe na gaze ya karubone isanzwe kandi wishingikirije kuri passivation ya stainless, cyangwa nziza nyamara, ihuza ibikoresho byose. Ingingo ni, gasketi ntishobora gutoranywa mu bwigunge.

Ibitekerezo byabatanga ibintu bifatika

Kuganira nababikora bitanga urumuri ku mbogamizi zifatika. Kubijwi byinshi, ibice bisanzwe, electrogalvanizing numwami kubera umuvuduko, igiciro, no kwisiga birangiye. Isosiyete nka Hamagara zitai yihuta ukora co., Ltd., ifite icyicaro gikuru cy’ibicuruzwa byihuta cyane mu Bushinwa i Yongnian, Hebei, irashobora gukoresha ibice byinshi bya gasketi isanzwe binyuze mumashanyarazi neza. Aho biherereye hafi yinzira nyabagendwa nka Gari ya moshi ya Beijing-Guangzhou hamwe n’umuhanda w’igihugu 107 ni inyungu y’ibikoresho byo gutanga ibyo bikoresho byoroheje, binini cyane ku isi. Urashobora kugenzura amaturo yabo asanzwe kurubuga rwabo kuri https://www.zitaifacens.com. Kuri bo, ni inzira isanzwe yujuje igice kinini cyibikenewe muri rusange.

Ariko, iyo ucukuye mubisabwa tekinike ya serivisi ikaze, ikiganiro kirahinduka. Abatanga ibintu kimwe bazasaba kenshi kwimuka bava mumashanyarazi meza kugirango bakoreshwe. Bashobora gutanga ibitekerezo nyuma yubuvuzi nka chromate ihinduranya (umuhondo, ubururu, cyangwa bisobanutse) byongeramo urwego rwo kurwanya ruswa mukunyuza hejuru ya zinc. Ibi bifasha gutinda gutangira ingese yera kandi, ku rugero ruto, ingese zitukura. Ariko ni ugutinda, ntabwo ari impinduka zifatika kubyimbye cyangwa ubushobozi bwo gutamba. Ku giciro gito cyane, ibishishwa bya zinc-flake (nka Geomet cyangwa Delta Protekt) bitanga imikorere isumba kure, kuko yubaka umubyimba mwinshi, urwanya inzitizi zirimo na aluminiyumu. Ariko ubu urimo kuva mubice byihuta bihendutse.

Ikiruhuko? Urunigi rwogutanga ibintu rwiza kubisanzwe. Kugaragaza ibidukikije bikaze bivuze ko ugomba guhitamo-guhitamo bisanzwe kandi akenshi ukitabira gahunda idasanzwe, bigira ingaruka kumwanya no kugiciro. Nubucuruzi-imishinga myinshi yibeshya mubyiciro byubwubatsi.

Ikibazo mu ngingo: Retrofit yatwigishije kurenza kunanirwa kwambere

Twari dufite akazi ka retrofit kumuyoboro wo hanze mubikoresho bya peteroli. Igipapuro cyumwimerere cyari ibyuma bya karubone bisanzwe, kandi byangiritse cyane kuri flanges, bisaba akazi ko gucana. Ivi-jerk reaction kwari ukuzamura amashanyarazi kugirango wirinde gukomera. Twakoze. Nyuma yimyaka ibiri, mugihe cyahindutse, twasanze gaseke nshya idafatanye, ariko yarangiritse cyane, hamwe no gutakaza umubyimba mwinshi. Ubuso bwa kashe bwarashyizweho kandi ntiburinganiye.

Ibidukikije byari umwicanyi combo: ibisigazwa byamazi rimwe na rimwe (ubushyuhe nubushuhe), ibinyabuzima bya sulfure bidukikije mu kirere, n'umunyu wo ku nkombe. Ipitingi ya electrogalvanised yari imaze igihe kinini. Isesengura rya post-mortem ryanzuye ko igicucu cya zinc cyakoreshejwe vuba mu mwaka wa mbere. Ibyuma by'ibanze bisigaye noneho byangirika ku muvuduko wihuse, birashoboka bitewe nigikorwa cyambere cya galvanic hamwe nibidukikije bikaze. Kuzamura mubyukuri byaduhaye umutekano wibinyoma kandi biganisha ku kashe yangiritse cyane kuruta niba twarakoresheje igicucu kinini, cyoroshye cyane kuva twatangira, cyangwa ibintu bitandukanye rwose.

Uku kunanirwa kwadusunikiraga kwerekana ubushyuhe bushyushye (hamwe no kwita ku kwihanganira ibipimo no gutonyanga) cyangwa zinc-flake kubikorwa nkibi bikabije. Kubibazo bikomeye rwose, twasibye ibyuma bya karubone byuzuye hanyuma twimukira muri aluminium cyangwa ibyuma bitagira umwanda, nubwo ibiciro byasimbutse. Igiciro cyose cyo kumeneka cyangwa guteganya guhagarika dwarf igiciro cyibikoresho.

Kwifata neza no Kugaragaza Amaso Yuguruye

None, umwanzuro ni uwuhe amashanyarazi yamashanyarazi aramba? Nibisabwa yego, hamwe na caveats ziremereye. Ugomba gusobanura bikabije. Nibisanzwe rimwe na rimwe, cyangwa ni spray itaziguye? Ntabwo pH itabogamye, cyangwa irahari gato? Ubushuhe ni ubuhe? Ibisobanuro birambuye kuruta ikirango cyagutse.

Amategeko yanjye akomeye kuri ubu: Niba ibidukikije byangiritse bihagije kuburyo bisaba ibirenze akazi ko gusiga amarangi ku byuma bikikije ibyuma, noneho amashanyarazi ya elegitoronike yonyine ku kintu gikomeye cyo gufunga ni urusimbi. Bitekerezeho kwisiga cyangwa byoroheje birinda kurangiza, ntabwo ari uburyo bukomeye bwo gukumira ruswa. Buri gihe ushire mubikorwa ingaruka zo gutsindwa. Igipapuro cyananiwe kumwanya winjira birababaje. Igicapo kimwe cyananiwe kumurongo wa peteroli mwinshi ni impanuka.

Hanyuma, andika ibidukikije muri spec yawe. Ntukandike gusa galvanised. Kugaragaza inzira (electrogalvanised kuri ASTM B633, Ubwoko bwa I, Fe / Zn 5), kandi nibishoboka, bisaba chromate ihinduranya (Ubwoko II) kugirango irwanye gato. Cyangwa, icyiza kurushaho, sobanura amasaha asabwa yo gutera umunyu kunanirwa (urugero, ASTM B117). Amasaha 96 adafite ingese itukura aratandukanye cyane namasaha 500. Ibi bihatira ibiganiro byimbitse hamwe nuwaguhaye isoko, yaba uruganda runini nka Handan Zitai twavuze haruguru cyangwa umugabuzi waho. Yimura ibiganiro kuva mubicuruzwa bikagera kubintu byakozwe, nibyo rwose gasike mubidukikije bigomba kuba.
