Ku masahani y’ingǒgo y’ivyuma bishushe akoreshwa mu mirongo y’ugutanga amashanyarazi, ugushirwa mu ngiro kw’uburyo bwo gukoresha ivyuma bishushe-bigena ata guca ku ruhande ubuzima bw’igikoresho n’ubushobozi bw’umutekano. Iki kiganiro kizotanga intangamarara ido n’ido iva ku mice y’ingingo ngenderwako z’imigenderanire, uburyo nyamukuru, ingingo nyamukuru zo kugenzura uburyo, inyungu z’imigenderanire, n’ingingo ngenderwako zo kwubahiriza ubudandaji n’amahanga.
Gutera ivyuma bishushe-dip ni ahanini igikorwa co gufatanya ivyuma. Iyo ingǒgo y’icuma isukuye ku ruhande -yibitswe mu zinc ishongesheje ku bushuhe bwa degre nka 450 , icuma (Fe) kiri mu gitereko c’icuma n’icuma (Zn) kiri mu gice c’icuma gishongeshejwe bica mu nzira idahera yo gukwiragira no gukorana, bikagira ivyuma bitatu {gal{4}ized layer. Kuva imbere gushika hanze, ivyo bipande ni:
Iron-Zinc Alloy Layer (Inner Layer): Ifatanye ata guca ku ruhande n’icuma, ahanini igizwe na Fe3Zn10 na FeZn7, irakomeye kandi irafise ubushobozi bwo kwifatanya cane, itanga ingwati nyamukuru y’uko ivyuma bishobora guhangana n’ugusenyuka be n’ubushobozi bwo kurwanya uburozi bw’ivyuma.
Zinc-Igipande c’Ivyuma (Igipande co Hagati): Gigizwe na FeZn13, gifise uburemere buringaniye kandi gifatanya ubukomezi n’ubukomezi.
Pure Zinc Layer (Outer Layer): Ipfutse igice co hanze cane, iraryoshe kandi irakomera, igakora igipande gikomeye co gukingira zinc oxide ku ruhande. Ikindi kandi, iyo habaye imikovu y’aho hantu, itanga uburinzi buhoraho ku hantu hakozwe biciye ku ngaruka y’uburinzi bw’ikimazi.
Ku bipande vy’ingǒgo vy’ivyuma bishaje, uburebure bwose bw’imiterere y’ibice bitatu-butegerezwa kugenzurwa cane kugira ngo bube hejuru ya 65μm. Ku bikorwa bisaba cane-, uburebure burashobora kwongerwa bukagera kuri 85μm kugira ngo bushitse ku bikenewe vy’ugutera umunyu mwinshi n’ibidukikije bishobora gusenyuka cane.
Uburyo bwo gukora amasahani y’ingǒgo y’ivyuma bishushe butegerezwa gukurikira uburyo busanzwe bwo gusuzuma imbere y’ugutera - ivyuma vy’ivyuma - inyuma yo gutera -. Muri izo, gutera imbere ni intambwe nyamukuru igena uburyo bwo gutera ivyuma kandi bikagira ico bikoze ata guca ku ruhande ku kwifatanya n’uguhuza kw’ivyo bikoresho.
Ivyo gukuraho amavuta: Koresha umuti wo gukuraho amavuta y’amazi kugira ngo ushire mu mazi ku bushuhe bwa degre 60-80 mu minota 5-10, canke ukoreshe uburyo bwo gusukura bukoresheje umuvuduko munini kugira ngo ukureho amavuta yo gutera ikidodo, amavuta yo gukingira umugese, inkungugu n’amabara y’amavuta ku ruhande rw’ivyo bikoresho. Ivyumba vy’ingǒgo biteye ikidodo be n’inkuta z’imbere z’ibinogo vy’amabuye ni ahantu hashobora gusigara amavuta, bikaba bisaba igihe kirekire co gutera canke gusukura bifashijwe n’ijwi ry’imbere.
Ukwoza amazi no kuyasukura: Ushobora gusukura biciye mu gitereko c’amazi c’intango n’ica kabiri kugira ngo ukuremwo ibintu bisigaye bikuramwo amavuta. Ivyo bitegerezwa gutuma ata mazi yirundanira canke ikintu gisigaye mu myobo y’amabuye.
Gutera aside n’ugukuraho umugese: Koresha aside y’amazi mu gutera, uyibike mu bushuhe bwo mu cumba iminota 10-15 kugira ngo ukureho umugera wa oxide, umugese, n’igice c’umugese kigendagenda ku ruhande rw’isahani y’ingǒgo. Ku rugero rw’ivyuma vy’amazi bikomeye cane, igihe co gutera ivyatsi gishobora kwagurwa neza, ariko birakenewe ko umuntu agenzura neza kugira ngo ntibishire ivyatsi birenze urugero, ivyo bikaba bishobora gutuma ahantu hagira ububabare kandi bikagabanya ukuntu ivyatsi bifatanya.
Ukwoza amazi no kuyakuramwo ubumara: Ubibike mu gitereko co gukuraho ubumara bw’amazi kugira ngo akuremwo ibintu vy’aside bisigaye, kugira ngo habe ahantu hatagira ubumara. Inkuta z’imbere z’ibinogo vy’amabuye zitegerezwa gusukurwa neza kugira ngo amasigarira y’aside ntatere ibivyimba mu gice c’ivyuma.
Drying and preheating: Dry at 120-150℃ for 10-15 minutes to completely remove surface moisture. The surface must be free of water stains and oxidation; otherwise, the galvanized layer may show signs of blistering or exposure to oxidized material. Defects such as those mentioned above; Zinc immersion: The zinc immersion temperature is strictly controlled at 445-460℃. The immersion time is adjusted according to the thickness of the plate. When the thickness is ≤6mm, the immersion time is 1-2 minutes. When the thickness is >6mm, igihe co kwibiza ni iminota 2-3. Ivyo gukonjesha: Koresha ugukonjesha kw’umuyaga canke ugukonjesha kw’amazi kugira ngo ukonjeshe gushika ku bushuhe bwo mu cumba. Mu gihe co gukonjesha, niwirinde gutombora hagati y’Ibipande vy’Ingogo vy’Igikoresho c’Igikoresho c’Igikoresho c’Igikoresho c’Igikoresho c’Igikoresho c’Igikoresho c’Igikoresho c’Igikoresho c’Igikoresho c’Igikoresho.
Ku bijanye na Hot Dip Galvanized Yoke Plates zirungikwa hanze, uburyo bwo kuzikora butegerezwa kuba buhuye n’ingingo mfatirwako zibereye be n’ibisabwa vyo kwemeza isoko ry’intumbero; ahandi ho ntibazoshobora kwinjira mw’isoko. Nk’umuhinguzi w’umwuga, ishirahamwe ryacu rishira imbere uburyo bw’ibicuruzwa; ndagusavye ntutinye kugura.
