Igicuruzwa Intangamarara

Intangamarara – Ni iki umuyoboro w’ivyuma & Ni igiki gishushe-Dip Gal

Igiti c’icuma gikomeye ni ubwoko bw’igiti c’icuma gipfutse igipande c’ivyuma gikingira ku ruhande rwaco. Ico gipfukisho ca zinc gikora nk’intambamyi y’umubiri be n’igipfukisho c’ikimazi, bisobanura yuko naho ico gipfukisho coba carakozweko, igipfukisho ca zinc kigikikuje kirabanza gusenyuka kugira ngo kikingire icuma kiri munsi yaco kugira ngo ntikigire umwuka. Ivyo bituma imiyoboro y’ivyuma ishobora gukomera cane mu bidukikije bifise ubukonje canke bishobora gusenyuka.
Hari uburyo bubiri busanzwe bwo gutera ivyuma:

Umuyagankuba-ugutera ivyuma– Igipande ca zinc gitoya, ahantu haryoshe, kifatanya neza, ariko n’ubushobozi bwo guhangana n’ugusenyuka buke cane.
Gushuha-ugutera ivyuma (HDG)– Umuyoboro w’icuma usukuwe wibizwa mu zinc iyunguruye ku bushuhe bwa degre 450–500 , ugahingura igice c’icuma-cyuma gifatanye n’icuma mu buryo bw’ubuhinga bw’ivyuma be n’igice co hejuru c’icuma gisukuye. Igipfukisho gishobora kuva kuri 35 μm gushika kuri 650 μm, kikaba gitanga ubushobozi bwo guhangana n’ugusenyuka n’ubuzima bwiza cane ugereranije n’ugukoresha umuyagankuba.

Kubera ko umuyoboro w’icuma gikomeye, uhuye kandi ufatanye cane, ukoreshwa cane mu gutanga amazi, mu gutanga gazi, mu bikorwa vy’ubuhinga bwa peteroli, mu kwubaka, mu gucungera amabarabara, no mu bikorwa vyo hanze, bikaba bitanga umuti w’uburinzi bw’ubutunzi kandi bw’igihe kirekire{1}}.

Ivyagezwe n'ibisobanuro bifitaniye isano

ASTM A123– Ivyuma vy’ivyuma n’ivyuma vy’ivyuma
ASTM A53 (Ihitamwo ry'ivyuma)– Umuyoboro w’icuma udafise umurongo kandi ushizwemwo amabuye
BS 1387– Amatiyo y'amazi, gazi n'umwotsi
GB/T 3091– Amatiyo y’icuma akozwe mu cuma co gutwara amazi afise umuvuduko muto

Uburyo bwo gukora / gupfuka

Intambwe	Imvugo
a. Gutegura ahantu hose	Amatiyo y’icuma arakurwako amavuta, arasukurwa, araterwa n’amazi (aside asukurwa) kugira ngo akuremwo umugera w’insyo n’umugese; flux ishobora gukoreshwa kugira ngo ntihagire oxidation igira oxidation imbere yo gutera galvaniser.
b. Kwibizwa muri Zinc iyunguruye	Amatiyo ashirwa mu bwogero bwa zinc bushonze ku bushuhe bwa degre nka 450-500 , ivyo bikaba bituma ubuhinga bwo gukora ivyuma bugira ibice vy’ivyuma vy’ivyuma n’ivyuma vy’inyuma vy’ivyuma vy’ivyuma.
c. Kuzimya / Gukonjesha	Amatiyo arakurwako, zinc irenze urugero ikarekurwa ngo isohoke, hanyuma igazimwa canke igakonjeshwa n’umuyaga kugira ngo iyo mpuzu ikomeze kandi igabanye utunenge.
d. Inyuma-Ubuvuzi / Guheza	Rimwe na rimwe gusukura amabuye y’agaciro, gusya amabuye y’agaciro iyo bikenewe, kumenya neza ko mbere asa n’uwundi; guhitamwo passivation canke coating hejuru y’ugutera ivyuma ku bw’igikorwa kinaka.
e. Gusuzuma no gusana	Suzuma uburemere bw’igipfukisho, utunenge tuboneka n’utudashobora gusenyura (imisi mikuru), ukuntu wifatanya, ukuntu uhuye ku mubiri, ukuntu ivyuma bifatanya n’indodo.

Uburyo bwo kwikingira

Uburinzi bw'intambamyi– Igipfukisho ca zinc gitandukanya ivyuma n’ubukonje n’umwuka w’ikirere.
Uburinzi bwa Katolika– Zinc irabora cane, ikingira ivyuma vyerekanwa iyo bikozweko canke ku mpande.
Ugufatanya kw'ibipande vy'ivyuma– Zinc-ivyuma vy’ivyuma bitanga ubufatanye bwiza cane kandi ntibishobora gusenyuka canke gusenyuka.

Inyungu nyamukuru (Vyagutse)

Ubuzima bwagutse– Mu bihe bisanzwe vy’ikirere, imiyoboro y’ivyuma ishobora kumara imyaka 30–50; mu bidukikije vy’inganda canke vyo ku nkengera y’ikiyaga, imyaka 15–20 yo gukingira ni ikintu gisanzwe.
Ugupfuka kwose– Itanga uburinzi bumwe ku muyoboro wose, harimwo n’ibifatanya, imfuruka, n’ibibanza bikomeye-ku-gushikako.
Igiciro-Birakora– Gutera ibara rimwe -bitanga uburinzi bw’imyaka mirongo, bikagabanya amafaranga yo kwitaho no gusubira gutera ibara mu kiringo c’ubuzima.
Ugukomera cane– Igipande c’icuma gikomeye cane gishobora guhangana n’ugushaza n’ugukubitwa n’ibintu mu gihe co gukoresha, gutwara, no gushiramwo.
Ibidukikije-Ivyiza– Zinc irashobora gusubirwamwo, kandi gukoresha ivyuma bishushe-bifise ingaruka nke ku bidukikije ugereranyije n’uburyo bwinshi bwo gushushanya.
Gusuzuma vyoroshe– Uburebure bw’igipfukisho n’uburyo bwo ku ruhande bishobora kugenzurwa bitagoranye hakoreshejwe ugusuzuma n’amaso canke ibipimo vy’uburemere.

Ibisobanuro bisanzwe

Kugenzura uburyo n'ubushobozi bwo gutanga

Ku muyoboro wa Octal, imiyoboro y'ivyuma ikoreshwa n'ivyuma ikoreshwa mu buryo bukomeye bwa QA/QC:

Igerageza ry'uburebure bw'igipfukisho (μm canke g/m2) ku rugero rwa ASTM/BS/GB
Ukwifatanya, uguhuza, n'igerageza ry'umunyu
Igenzura ry'ingero ryose n'iry'amaso kugira ngo umuntu yizere ko ata n'akanenge -aheza
Ivyo bikoresho bishobora guhinduka bifise ubwoko bwinshi bw'ivyuma, uburebure n'uburebure
Inyandiko z'uburyo bwuzuye n'ugukurikirana kugira ngo umugambi wemererwe
