Nigute wakwirinda kwangirika kwicyuma?
Hamwe no kwiyongera kwibyuma bisohoka, ibyuma nibyinshi birakunzwe.Ikoreshwa cyane nkububiko, amahugurwa, igaraje, inzu ya prefab, inzu yubucuruzi, stade prefab, nibindi. Ugereranije ninyubako za beto zubakishijwe ibyuma, inyubako zubatswe nicyuma zifite ibyiza byo kubaka byoroshye, imikorere yimitingito myiza, kutangiza ibidukikije no kongera gukoreshwa.Nyamara, ibyuma byubatswe byoroshye kubora, bityo anti-ruswa ningirakamaro cyane mubyuma.
Ubwoko bubora bwububiko bwibyuma birimo kwangirika kwikirere, kwangirika kwaho no kwangirika.
(1) Ruswa ya Atmospheric
Kwangirika kwa Atmospheric ibyuma byubatswe ahanini biterwa ningaruka za chimique na electrochemicique yamazi na ogisijeni mukirere.Umwuka w’amazi mu kirere ukora urwego rwa electrolyte hejuru yicyuma, kandi ogisijeni yo mu kirere irashonga muri yo nka cathode depolarizer.Bakora ibyingenzi byangirika galvanic selile hamwe nibyuma.Iyo ingese imaze kuboneka hejuru yicyuma cyangirika kwikirere, ibicuruzwa byangirika bizagira ingaruka kuri electrode yangirika kwikirere.
(2) Ruswa yaho
Ruswa yaho niyo ikunze kugaragara mubyubatswe mubyuma, cyane cyane kwangirika kwa galvanic no kwangirika.Kwangirika kwa Galvanic kugaragara cyane mubyuma bitandukanye cyangwa guhuza ibyuma.Icyuma gifite ingaruka mbi zishobora kwangirika vuba, mugihe icyuma gifite ubushobozi bwiza kirarinzwe.Ibyuma byombi bigize ingirabuzimafatizo ya galvanic.
Kwangirika kwa crevice kugaragara cyane cyane mubuso bwubuso hagati yimiterere itandukanye yimiterere yimiterere yicyuma no hagati yicyuma nicyuma.Iyo ubugari bwa crevice bushobora gutuma amazi ahagarara muri ruhurura, ubugari bworoshye cyane bwubugari bwibyuma byubatswe ni 0.025 ~ o.1mm.
(3) Shimangira ruswa
Muburyo bwihariye, ibyuma byubaka bifite ruswa nke mugihe bidahangayitse, ariko nyuma yo guhura nimpagarara zikomeye, ibice bizacika gitunguranye nyuma yigihe runaka.Kuberako nta kimenyetso kigaragara cyo kuvunika kwangirika hakiri kare, akenshi biganisha ku ngaruka mbi, nko gusenyuka kw'ikiraro, kumeneka kw'imiyoboro, gusenyuka kw'inyubako n'ibindi.
Ukurikije uburyo bwo kwangirika bwimiterere yicyuma, kwangirika kwayo ni ubwoko bwangiritse butaringaniye, kandi ruswa ikura vuba.Ubuso bw'imiterere y'ibyuma nibumara kwangirika, urwobo rwangirika ruzatera imbere byihuse kuva mu rwobo kugera ku bujyakuzimu, bikavamo kwibanda ku miterere y'ibyuma, bizihutisha kwangirika kw'ibyuma, bikaba ari uruziga rukabije.
Ruswa igabanya ubukonje bukabije bwimbaraga nimbaraga zumunaniro wibyuma, bikaviramo kuvunika gutunguranye kwibintu bitwara imitwaro nta bimenyetso bigaragara byerekana ko byahindutse, bikaviramo gusenyuka kwinyubako.
Uburyo bwo kurinda ibyuma byubaka
1. Koresha ibyuma birwanya ikirere
Icyuma giciriritse cyicyuma hagati yicyuma gisanzwe nicyuma.Ibihe byikirere bikozwe mubyuma bisanzwe bya karubone hamwe nibintu bike birwanya ruswa nka muringa na nikel.Ifite ibiranga imbaraga nubukomezi, kwagura plastike, gukora, gusudira no gukata, abrasion, ubushyuhe bwinshi no kurwanya umunaniro wibyuma byo mu rwego rwo hejuru;Kurwanya ikirere bikubye inshuro 2 ~ 8 icyuma gisanzwe cya karubone, kandi imikorere yo gutwikira ikubye inshuro 1.5 ~ 10 icyuma gisanzwe.Muri icyo gihe, ifite ibiranga kurwanya ingese, kurwanya ruswa yibigize, kwagura ubuzima, kugabanuka no kugabanya ibyo ukoresha, kuzigama abakozi no kuzigama ingufu.Ikirere gikoreshwa cyane cyane mubyuma byubatswe nikirere igihe kirekire, nka gari ya moshi, ibinyabiziga, ibiraro, iminara nibindi.Ikoreshwa mu gukora kontineri, ibinyabiziga bya gari ya moshi, derricks ya peteroli, inyubako zo ku cyambu, urubuga rutunganya amavuta hamwe n’ibikoresho birimo hydrogène sulfide itangaza ruswa mu bikoresho bya shimi na peteroli.Ingaruka yubushyuhe bwo hasi nayo irakomeye kuruta icyuma rusange cyubatswe.Igipimo ni ikirere cyuma cyubatswe (GB4172-84).
Amorphous spinel oxyde igizwe na metero 5O ~ 100 m zakozwe hagati ya ruste na matrix ni nyinshi kandi ifatanye neza nicyuma cya matrix.Bitewe nuko iyi firime yuzuye ya oxyde, irinda kwinjiza ogisijeni namazi mukirere muri matrike yicyuma, bidindiza iterambere ryimbitse ryangirika ryibikoresho byibyuma, kandi bitezimbere cyane kurwanya kwangirika kwikirere kwangiza ibikoresho byibyuma.
2. Gushyira ibishyushye
Kwirinda gushyushya ruswa birinda ruswa ni ugushira igihangano kugirango ushyirwe mu bwogero bwicyuma cya zinc cyashongeshejwe kugirango ushyireho isahani, kugirango ubashe gukora zinc itwikiriye hejuru yumurimo wakazi hamwe na zinc ivanze hejuru ya kabiri, kugirango ubimenye kurinda ibyuma n'ibyuma.
3. Arc gutera anticorrosion
Gutera Arc nugukoresha ibikoresho byihariye byo gutera kugirango ushongeshe insinga zicyuma zatewe nigikorwa cyumuvuduko muke hamwe numuyoboro mwinshi, hanyuma ukayitera kubice byicyuma mbere yumusenyi kandi bigasenywa numwuka uhumeka kugirango ube arc spray zinc na aluminiyumu, aribyo yatewe hamwe na kashe yo kurwanya ruswa kugirango ikore igihe kirekire cyo kurwanya ruswa.Igipfundikizo cyinshi kirashobora gukumira neza uburyo bubora butangirika muri substrate.
Ibiranga arc gutera anti-ruswa ni: igifuniko gifatanye cyane, kandi gufatana kwayo ntagereranywa n irangi rikungahaye kuri zinc hamwe na zinc zishyushye.Ibisubizo by'ibizamini byunamye ku gihangano cyakorewe hamwe na arc gutera imiti igabanya ubukana ntabwo yujuje gusa ibipimo bijyanye, ariko bizwi kandi nka "plaque yamashanyarazi";Igihe cyo kurwanya ruswa cyo gutera arc gutera ni kirekire, muri rusange 30 ~ 60A, kandi uburebure bwa coating bugena ubuzima bwo kurwanya ruswa.
4. Kurwanya ruswa yubushyuhe bwa aluminiyumu (zinc)
Gutera ubushyuhe bwa aluminiyumu (zinc) ikomatanya ni uburyo bwigihe kirekire bwo kurwanya ruswa hamwe ningaruka zimwe na galvanizing ishyushye.Inzira nugukuraho ingese hejuru yumunyamuryango wibyuma muguturika umucanga, kugirango ubuso bugaragare hamwe nicyuma cyumucyo kandi gikomye;Noneho koresha umuriro wa ogisijeni wa acetylene kugirango ushonge insinga ya aluminium (zinc) ikomeza koherezwa hejuru yicyuma cyumuyaga uhumeka kugirango ukore ubuki bwa aluminiyumu (zinc) itera (uburebure bwa 80 ~ 100m);Hanyuma, imyenge yuzuyemo epoxy resin cyangwa irangi rya neoprene kugirango ikore igifuniko.Ubushyuhe bwatewe na aluminium (zinc) ikomatanya ntishobora gukoreshwa kurukuta rwimbere rwabanyamuryango.Kubwibyo, impande zombi zabanyamuryango zigomba gufungwa umuyaga mwinshi kugirango wirinde kwangirika kurukuta rwimbere.
Ibyiza byiyi nzira nuko ifite imiterere ihuza cyane nubunini bwibigize, kandi imiterere nubunini bwibigize ntibigira umupaka;Iyindi nyungu nuko ingaruka ziterwa nubushyuhe bwibikorwa byaho, bityo ibice ntibizabyara ubushuhe.Ugereranije na hot-dip galvanizing, urwego rwinganda zo gutera amashyanyarazi ya aluminium (zinc) ikomatanya ni mike, ubukana bwumurimo wo guturika umucanga na aluminium (zinc) ni mwinshi, kandi ubwiza nabwo bugira ingaruka kuburyo bworoshye nimpinduka zamarangamutima yabakora .
5. Gupfuka anticorrosion
Igipfundikizo kirwanya ruswa yimiterere yicyuma gikenera inzira ebyiri: kuvura shingiro no kubaka ubwubatsi.Intego yo kuvura amasomo yibanze ni ugukuraho burr, ingese, amavuta yandi mavuta hamwe nibindi bifatanye hejuru yibigize, kugirango ugaragaze urumuri rwinshi hejuru yibigize;Nuburyo bunoze bwo kuvura shingiro, nibyiza ingaruka zifatika.Uburyo bwibanze bwo kuvura burimo kuvura intoki nubukanishi, kuvura imiti, kuvura imiti, nibindi.
Kubijyanye no kubaka ibifuniko, uburyo bukoreshwa cyane bwo gukaraba burimo uburyo bwo koza intoki, uburyo bwo kuzunguruka intoki, uburyo bwo gutwika, uburyo bwo gutera ikirere hamwe nuburyo bwo gutera umwuka.Uburyo bwiza bwo gukaraba burashobora kwemeza ubuziranenge, gutera imbere, kuzigama ibikoresho no kugabanya ibiciro.
Kubijyanye nuburyo bwo gutwikira, hari uburyo butatu: primer, irangi ryo hagati, primer, primer na primer.Primer ahanini igira uruhare rwo gufatira hamwe no kwirinda ingese;Ikoti ryo hejuru rifite uruhare runini rwo kurwanya ruswa no kurwanya gusaza;Imikorere yo gusiga irangi iri hagati ya primer no kurangiza, kandi irashobora kongera ubunini bwa firime.
Gusa iyo primer, ikote ryo hagati hamwe na kote yo hejuru bikoreshejwe hamwe birashobora kugira uruhare rwiza no kugera ku ngaruka nziza.
