Amashanyarazi yashizwemo icyapa kiramba? 

Reka tugabanye ibicuruzwa byo kwamamaza. Iyo umuntu abajije ibijyanye no kuramba kw'isahani yashizwemo amashanyarazi, akenshi abaza ati: Iki kintu kizangirira imyaka itanu, cyangwa nshobora kubyibagirwa? Igisubizo kigufi, kitorohewe ni: biterwa rwose nibyo urimo, kandi cyane cyane, ibyo uhuza nabyo. Nabonye amasahani asa neza nyuma yimyaka icumi nabandi batangira kwerekana ingese zera zera munsi yimyaka ibiri. Ikosa risanzwe ni ugufata zinc nkingabo yubumaji, ukirengagiza ishyingiranwa ryamashanyarazi-cyangwa intambara-ryinjira rimaze gushyirwaho.

Ukuri kw'igitambo cya Zinc

Electro-galvanizing ninzira yo gukoreramo kubwimpamvu. Birahendutse cyane, bitanga igifuniko gihamye, cyoroshye, kandi gitanga uburinzi bwiza bwo kubora kubisahani ubwabyo mubidukikije byinshi. Imvugo y'ingenzi ni iy'isahani ubwayo. Mugihe uzunguza sitidiyo cyangwa ugahindura ikintu unyuzemo, wangije igifuniko icyo gihe. Ikibazo kiramba noneho gihinduka kuva ku isahani kuri sisitemu yihuta. Niba ukoresha ibyuma bya karubone, waremye couple ya galvanic. Zinc izarinda ibitambo ibyo biti, byangirika byihuse aho bihurira. Ndibuka umushinga wo kubika ububiko aho twakoresheje ibyapa bisanzwe bya EG hamwe nicyuma gisanzwe. Isahani yari nziza, ariko imitwe ya ankeri yari akajagari k'ingese itukura mu myaka itatu muri kiriya gice cy'imbere. Gukosora ntabwo byari binini bya zinc ku isahani; yahindurwaga kuri hot-dip galvanised cyangwa ndetse na ankore idafite ingese kugirango ihuze neza na galvanic.

Ubunini bwo gutwikira ni umurongo wawe wambere wo kwirwanaho, ariko ntabwo ari umubare gusa kurupapuro rwihariye. Igikoresho cya 5-micron gishobora kuba gihagije kuburyo bwumutse, bugenzura imbere. Gerageza ibyo ku isahani yashyizwe mumurongo wa beto muri garage yaparika aho imyunyu ya de-icing ikoreshwa, kandi uzareba kunanirwa mugihe cyizuba. Amategeko? Kubisohoka hanze, biciriritse-serivisi ya porogaramu, ndatinda kwerekana ikintu cyose kiri munsi ya microne 12. Ndetse no muri icyo gihe, ntabwo bijyanye n'uburinganire gusa. Impande, gukata impera, hamwe na weld zone niho gutsindwa bitangirira. Utanga isoko nziza azagira uburyo bugenzurwa bwo kongera gutwikira cyangwa gufunga utu turere nyuma yo guhimbwa, ariko iyo ni intambwe yinyongera kandi bisaba benshi kugerageza gusimbuka.

Noneho hariho gutegura ibyuma fatizo. Aha niho utandukanya abatanga ikinyabupfura nibibazo bitera ibibazo. Niba ibyuma bidasukuwe neza kandi bigatorwa mbere yo kwiyuhagira zinc, gufatira ni bibi. Nabonye gutwikira ibisebe no gukuramo impapuro mugihe cyo gukora, kereka muri serivisi. Nukunanirwa ushobora kubona hakiri kare niba uzi icyo ushakisha: isura ihindagurika gato cyangwa gufatana nabi kuruhande. Isosiyete nka Hamagara zitai yihuta ukora co., Ltd., ishingiye mu Bushinwa bukomeye bwihuta muri Yongnian, mubusanzwe ifite igipimo nigenzura ryogucunga buri gihe, niyo mpamvu biva mubucuruzi bwashizweho bifite akamaro. Aho biherereye hafi yinzira nini zitwara abantu nka Gari ya moshi ya Beijing-Guangzhou bivuze ko zashyizweho kubwinshi, ubuziranenge busanzwe, ntabwo ari imirimo yubukorikori imwe.

Ibidukikije byashyizwemo ni Umwami

Ntushobora kuvuga isahani iramba utavuze kuri beto. Nibihinduka binini. Byinshi-alumina cyangwa chloride yanduye ni igihano cyurupfu kubicyuma cyose cyashyizwemo, amashanyarazi cyangwa ntayo. Ibidukikije bya alkaline ya beto nziza-nziza ifasha kwinyuramo zinc, ikora urwego ruhamye rutinda kwangirika. Ariko beto ntabwo ari ikintu kimwe. Nagize uruhare mu mushinga wo mu nyanja aho spec yahamagaye amashanyarazi. Byari ibyago bitegereje kubaho. Guhora kwa chloride ituruka kumiti yumunyu na splash zone yinjira byarenze ubushobozi bwigitambo cya zinc vuba. Twagombaga gukora umushinga wo guhindura umushinga wo hagati kuri epoxy-yometseho rebar hamwe nudukoni twa karuvati, hamwe nibisahani byahinduwe kugirango bishyushye. Isomo rihenze mugusuzuma ibidukikije.

Kwangiza kwishyiriraho nundi mwicanyi ucecetse. Abakozi bajugunya amasahani mu buryo, bakayagenderaho, cyangwa bafite akazu kegeranye hejuru yabo barashobora gushushanya igipfunsi kugeza ku cyuma cyambaye ubusa. Iyo bimaze gushyirwamo, icyo gishushanyo gihinduka anode muri selile ya galvanic, byihuta kwangirika. Ubu ndatsimbaraye ku ngamba zoroshye zo gukingira nka kaseti y'agateganyo ku bice bifatanye cyangwa kwerekana ko amasahani ashyirwa nyuma ya materi ya rebar yashizweho. Yongeraho wenda 5% mugihe cyakazi ariko irashobora gukuba kabiri ubuzima bwiza bwa serivisi.

Tuvuge iki ku guhuza ibindi byuma? Aha niho ibishushanyo mbonera bya galvanic bihinduka gusoma igihe cyo kuryama. Guhuza isahani ya electro-galvanised (ibyuma bisizwe na zinc) n'umuringa ukwiranye cyangwa umuyoboro w'umuringa munsi y'ubutaka birasaba ibibazo. Zinc izangirika cyane kugirango irinde umuringa mwiza cyane. Nabonye ibi mumashanyarazi yingirakamaro. Igisubizo ni ukwigunga-ukoresheje dielectric bushings cyangwa koza kugirango ucike inzira y'amashanyarazi hagati y'ibyuma bidasa. Nibintu bito, bihendutse hafi ya byose birengagizwa muburyo bwambere.

Iyo Ibyiza Bihagije Ntabwo

Hariho umwanya nahantu ho gushiramo amashanyarazi. Imbere, ibidukikije byumye, ibikoresho byubukanishi aho bihurira na zinc? Nuburyo bwiza, guhitamo neza. Ibibazo bivuka iyo bikoreshejwe nkibisobanuro bidasanzwe nta mpamvu. Nasuzumye ibishushanyo byinshi byubatswe aho buri embed igaragara EG gusa kuko yari kumurongo wanyuma.

Twakoze ikigereranyo cyo kugereranya hashize imyaka mike, dushyingura ibyapa byintangarugero mubikorwa bitandukanye mubwobo bwikizamini hamwe nubutaka bwibasiwe nubunyu. Ingero za electro-galvanised zerekanye igihombo gikomeye cya zinc hamwe no kwangirika kwibyuma kumpera mumezi 18. Ingero zishyushye zashizwemo intangarugero zari zitangiye kwerekana zinc patina. Ingero zicyuma? Biboneka bidahindutse. Ikigereranyo cyibiciro cyari hafi 1: 1.5: 4. Ikigereranyo cyo kuramba nticyari umurongo; byari bimeze nka 1: 3: 20 muri ibyo bidukikije. Urubanza rwubucuruzi rwo gukoresha byinshi imbere rwarasobanutse neza kubyo gusaba byihariye.

Aha niho ibiganiro byo gutanga bigerwaho. Kubwinshi, isahani isanzwe, uwukora nka Zitai yihuta (urashobora kubona intera yabo kuri https://www.zitaifacens.com) birumvikana. Bitanga ku gipimo cyemeza inzira ihamye kumanota asanzwe hamwe na coatings. Ariko kubidukikije binengwa cyane cyangwa byangirika, ushobora gukenera kurenga kurutonde rwabo rusanzwe - ukerekana igipfundikizo kinini, uburyo bwo kuvura chromate nyuma yo gusya, cyangwa nicyuma gitandukanye. Ikibazo nukumenya niba umurongo wabo wo kubyara woroshye bihagije kubyo byateganijwe, cyangwa niba umeze neza hamwe nuwabihimbye.

Uburyo bwo Kunanirwa nicyo Kureba

Kunanirwa kuramba ntibisobanura gake gufata isahani mo kabiri. Ni ugutakaza imikorere. Uburyo busanzwe ni gufata urudodo. Zinc irabora kumutwe wudusudo dusudira, kwaguka no gufunga ibinyomoro. Njye namaze amasaha mabi kurubuga hamwe ningaruka zingaruka hamwe namatara ngerageza kubohora utubuto ku mbuto zari zifite imyaka itandatu gusa. Gukoresha urudodo ruto cyangwa gushira hejuru-zinc anti-seise paste mugihe cyo kwishyiriraho biroroshye, mituweli ihendutse hafi ya yose ntisanzwe.

Ikindi kigabanywa imbaraga zo gukuramo. Nkuko isahani hamwe na sitidiyo yayo bigenda byangirika, ibice byambukiranya bigabanuka. Ibi nibyingenzi kumutekano wingenzi nka sisitemu yo gukingira kugwa cyangwa guhuza imitingito. Ntabwo dufite uburyo bwiza budasenya bwo kugenzura ibi bimaze gushyirwamo, niyo mpamvu ibisobanuro byambere hamwe no gusuzuma ibidukikije ari ngombwa. Niba uri kugenzura imiterere ihari, shakisha ingese irira kuva kuri beto ikikije emb. Nicyo kimenyetso cyo kuvuga ibimenyetso bya ruswa ikora. Mugihe ubonye ko, gutakaza igice bimaze kuba ingirakamaro.

Rimwe na rimwe, kunanirwa ni byiza. Ingese yera (zinc oxyde) yanduye hejuru ya beto yuzuye. Ntabwo byubatswe muburyo hakiri kare, ariko birasa nabi kuruhande. Ibi bikunze kubaho mugihe amasahani abitswe mubihe bitose mbere yo gushiramo, bigatuma ububiko butose. Nibibazo byo kugenzura ubuziranenge kubitanga cyangwa ububiko. Utanga ibintu byiza azumisha neza hamwe namasahani yo gukumira ibi. Niba urimo kubona amasahani asanzwe yerekana ubuso bwera, ifu yubusa uhereye kumasanduku, ubyange. Iyo myenda irinda yamaze gukoreshwa igice mbere yuko ikora akazi kayo.

Icyemezo: Guhitamo Kubarwa

None, isahani yashizwemo amashanyarazi iraramba? Irashobora kuba, ariko kuramba kwayo ntabwo ari umutungo wimbere. Ni umutungo wa sisitemu. Urimo kugura igice hamwe nigitambo. Igihe cyacyo giterwa nigitero cyibidukikije, ubwiza bwibisabwa, ibyuma bikoraho, hamwe nubwitonzi mugihe cyo kwishyiriraho. Ntabwo ari ugushiraho no kwibagirwa igisubizo cyibihe bibi.

Kubidakomeye, imbere, cyangwa ibidukikije bigenzurwa, ni amahitamo meza yubukungu. Kugaragaza umubyimba muto usobanutse neza (Nakwemeza kuri microne 12+ kubintu byose bitari amagufwa-yumye), saba ibyemezo byuwabikoze, kandi urebe ko ibyuma byose bifatanye bifite igifuniko gihuje. Kubidukikije, bitose, cyangwa chloride yibidukikije, birashoboka ko wazamuka ukazamura umurongo urambuye ugashyuha-ushyushye cyangwa ukanika imashini kugirango ubyibushye cyane. Kubintu bikomeye cyane cyangwa byangirika, igiciro cyambere cyambere cyibikoresho bidafite ibyuma nibyo byonyine bihitamo ubushishozi.

Mu kurangiza, biza kuri ibi: gusobanura ibidukikije bya serivisi hamwe nubuzima bwa serivisi bukenewe mbere. Noneho subiza inyuma isahani hamwe nibihuza. Ntugasubire gusa kuri electro-galvanised kuko nikintu cyumurongo abantu bose bazi. Ibyo bitekerezo bidasubirwaho nibyo biganisha kunanirwa imburagihe, guhamagarwa, no gusana bihenze. Kuramba birahari, ariko gusa niba wabishushanyije.
