Ubushinwa Bwashyushye Umuyoboro wicyuma / Umuyoboro wicyuma, ASTM A53 API 5L
Incamake
Birashobora kuba inshingano zacu guhaza ibyo ukunda kandi biguha ubushobozi. Guhazwa kwawe nigihembo cyacu gikomeye. Turashaka imbere yuruzinduko rwawe kugirango dukure hamwe. Kubera imbaraga zacu, ibicuruzwa byacu byatsindiye abaguzi kandi byagurishijwe cyane kimwe hano ndetse no mumahanga. Uruganda rwacu rwatsimbaraye ku ihame rya "Ubwiza Bwambere, Iterambere Rirambye", kandi rifata "Ubucuruzi buvugisha ukuri, inyungu za mugenzi wawe" nkintego yacu yiterambere. Abanyamuryango bose ndashimira byimazeyo inkunga yabakiriya bose bashya kandi bashya. Tuzakomeza gukora cyane tunaguha ibicuruzwa na serivisi nziza.
Ibyerekeranye nicyuma cya karubone gisudira kandi kidafite kashe, kugirango byongere ubushobozi bwo kurwanya ruswa, hazabaho uburyo bunoze bwo kuvura imiyoboro. Imwe murimwe ikoreshwa cyane ni ikote rya zinc (galvanize). Hariho uburyo bubiri bwa galvanize: glavanizing ikonje (electrogalvanizing) hamwe na galvaniza. Kuberako ikibazo cyibidukikije, glavanizing ikonje yagabanutse mubushinwa, kandi galvanizing nayo ntishobora gukoreshwa nkumuyoboro wogutanga amazi, ariko ikoreshwa cyane mukuzimya umuriro, amashanyarazi numuhanda.
Ubukonje bukonje ni amashanyarazi, kubera imipaka yubuhanga, ikote rya zinc ntabwo ari myinshi, cyane cyane muri 10-50g / m2, kubwibyo, ubushobozi bwayo bwo kurwanya ruswa ntabwo ari munsi ya hoteri. Minisiteri y’ubwubatsi yahagaritse ku mugaragaro kurandura imiyoboro ikonje ikonje ikoresheje ikoranabuhanga ryasubiye inyuma, kandi birabujijwe gukoresha imiyoboro ikonje ikonje mu miyoboro y’amazi na gaze. Icyuma cya galvanizike yumuyaga ukonje-dip galvanised umuyoboro nicyuma cya electroplated, naho zinc layer na substrate yicyuma byubatswe byigenga. Igice cya zinc ni gito cyane, kandi urwego rwa zinc rwizirika gusa kumashanyarazi yicyuma kandi byoroshye kugwa. Kubwibyo, kurwanya ruswa kwayo ni bibi.
Umuyoboro ushyushye wa galvanizing umuyoboro ushyirwaho nigikorwa cyicyuma gishongeshejwe hamwe nicyuma cyuma, kuburyo substrate hamwe nicyuma gishyizwe hamwe, kandi igipande nticyoroshye kugwa. Gushyushya ibishyushye bifite ibyiza byo gutwikira kimwe, gukomera hamwe no kuramba kuramba. Amashanyarazi ashyushye ashyushye hamwe nicyuma gishongeshejwe gikozwe mumashanyarazi bigira ingaruka zikomeye kumubiri no mubumara kugirango habeho ruswa idashobora kwangirika ya zinc-fer alloy layer hamwe nuburyo bworoshye. Umuti wa aliyumu uhujwe na zinc yuzuye hamwe na pisitoro yicyuma, bityo irwanya ruswa irakomeye.
Gusaba
Irakoreshwa Cyane kubice byingufu nigitutu, no mubikorwa rusange ibyuka, amazi, gaze numuyoboro wikirere.
