Umuyoboro ushyushye

Icyuma gishongeshejwe gifata matrike yicyuma kugirango kibyare uruvange, kuburyo matrix hamwe nigitambaro byahujwe. Amashanyarazi ashyushye ni ukubanza gutora umuyoboro wibyuma, kugirango ukureho okiside yicyuma hejuru yumuyoboro wicyuma, nyuma yo gutoragura, ukoresheje amonium chloride ya amonium cyangwa zinc chloride yumuti wamazi cyangwa chloride ya amonium na zinc chloride ivanze nigituba cyamazi yo kwisukura, hanyuma ikinjira mubigega bishyushye. Gushyushya ibishyushye bifite ibyiza byo gutwikira kimwe, gukomera hamwe no kuramba kuramba. Byinshi mubikorwa byo mumajyaruguru bifata inzira yo kuzuza zinc ya galvanised umukandara utaziguye.

Umuyoboro ukonje

Ubukonje bukonje ni amashanyarazi, amashanyarazi ni make cyane, 10-50g / m2 gusa, kwihanganira kwangirika kwayo gutandukanye cyane numuyoboro ushyushye. Abakora imiyoboro isanzwe ya galvanised, kugirango barebe ubuziranenge, benshi ntibakoresha amashanyarazi (plaque ikonje). Gusa iyo mishinga mito ifite ibikoresho bitagikoreshwa ikoresha amashanyarazi, birumvikana ko ibiciro byayo bihendutse. Mu bihe biri imbere, imiyoboro ikonje ikonje ntabwo yemerewe gukoreshwa nk'imiyoboro y'amazi na gaze.

Umuyoboro ushushe ushyushye

Imyitwarire igoye yumubiri nubumashini bibaho hagati yicyuma cyogosha nicyogero cyashongeshejwe kugirango kibe icyuma cya zinc-fer cyoroshye kandi kirwanya ruswa. Umuti wa alloy urahujwe hamwe na zinc nziza kandi matrike yicyuma. Kubwibyo, kurwanya ruswa kwayo birakomeye.

Nyuma yo guteza imbere umuyoboro w’icyuma ushyushye mu myaka ya za 1960 kugeza mu myaka ya za 70, ubwiza bw’ibicuruzwa bwarazamutse cyane, 1981 kugeza 1989 buhabwa Minisiteri y’ubutare y’ibicuruzwa byujuje ubuziranenge ndetse n’igihembo cy’ifeza mu gihugu, umusaruro nawo wiyongereye mu myaka myinshi, 1993 umusaruro wa toni zirenga 400.000, 1999 uva muri toni zirenga 600.000, kandi woherezwa mu majyepfo y’amajyepfo ya Aziya, Afurika, Amerika, Ubuyapani, Ubudage n’ibihugu. Imiyoboro ishyushye cyane ikoreshwa cyane nk'imiyoboro y'amazi n'imiyoboro ya gaze, kandi ibisobanuro rusange ni + 12.5 ~ + 102 mm. Nyuma ya za 90, kubera ko leta yitaye cyane ku kurengera ibidukikije, kugenzura imishinga y’umwanda mwinshi biragenda birushaho gukomera, "imyanda itatu" itangwa mu gukora imiyoboro y’amashyanyarazi ashyushye biragoye kuyikemura, ijyanye n’iterambere ryihuse ry’imiyoboro isudira ibyuma, imiyoboro ya PVC hamwe n’imiyoboro ihuriweho, ndetse na leta kugira ngo iteze imbere ikoreshwa ry’ibikoresho bya chimique, hamwe n’ibihugu bigamije guteza imbere ikoreshwa ry’ibikoresho bya chimique, hamwe n’igihugu kugira ngo biteze imbere ikoreshwa ry’ibikoresho bya chimique, imiyoboro isudira ya galvanised yibasiwe cyane na Beam na limit, umuyoboro ushyushye wa galvanised umuyoboro weld nyuma nyuma ukura buhoro buhoro.

Umuyoboro w'icyuma ukonje

Igice cya zinc ni icyuma gikoresha amashanyarazi, kandi igipimo cya zinc cyigenga cyigenga hamwe na matrike yicyuma. Igice cya zinc ni cyoroshye, kandi igipande cya zinc gifatanye gusa na materique yicyuma kandi byoroshye kugwa. Kubwibyo, kurwanya ruswa kwayo ni muke. Mu nyubako nshya zo guturamo, birabujijwe gukoresha imiyoboro ikonje ikonje nk'imiyoboro itanga amazi.
