Icyitegererezo cyubuntu kubushinwa ASTM A53 / BS1387 Urudodo rufatanije kandi rushyizwe hamwe rushyushye rwashyizwemo umuyoboro wibyuma
Incamake
Buri munyamuryango ku giti cye avuye mu bikorwa byinshi byinjiza abakozi baha agaciro ibyo abakiriya bakeneye ndetse n’itumanaho ryishyirahamwe rya ASTM A53 / BS1387 Umuyoboro ushushe wa Galvanized Umuyoboro el Hamwe natwe amafaranga yawe mukurinda ubucuruzi bwawe mumutekano. Twizere ko dushobora kuba abaguzi bawe bizewe mubushinwa. Dutegereje ubufatanye bwawe .Mu myaka irenga 9 y'uburambe hamwe n'itsinda ry'umwuga, twohereje ibicuruzwa byacu mu bihugu byinshi no mu turere twinshi ku isi. Twishimiye abakiriya, amashyirahamwe yubucuruzi ninshuti ziturutse impande zose zisi kutwandikira no gushaka ubufatanye kubwinyungu rusange.
Gushyushya-guswera bifite ibyiza byo gutwikira kimwe, gukomera hamwe no kuramba kuramba. Imyitwarire igoye yumubiri na chimique iba hagati ya matrike yicyuma nigisubizo cyashongeshejwe kugirango kibe ruswa idashobora kwangirika kwangirika kwa zinc-fer alloy layer. Umuti wa alloy wahujwe hamwe na zinc nziza kandi matrike yicyuma. Kubwibyo, kurwanya ruswa kwayo birakomeye.
Twabibutsa ko 1960 na 1970, ibihugu byateye imbere kwisi byatangiye guteza imbere ubwoko bushya bwimiyoboro kandi buhoro buhoro bibuza imiyoboro ya galvanis. Minisiteri na komisiyo enye zirimo Minisiteri y’ubwubatsi n’Ubushinwa nazo zasohoye inyandiko isobanura ko imiyoboro ya galvanis yabujijwe guhera mu 2000. Imiyoboro ya galvaniside ikoreshwa gake mu miyoboro y'amazi akonje mu baturage bashya, kandi imiyoboro ikoreshwa mu miyoboro y'amazi ashyushye mu baturage bamwe.
Gusaba
Irakoreshwa Cyane kubice byingufu nigitutu, no mubikorwa rusange ibyuka, amazi, gaze numuyoboro wikirere.
