Ku rwego mpuzamakungu, ingingo ngenderwako nka ASTM A740 na EN 10223-3 zirakurikizwa, zifise ibisabwa bitomoye ku buremere bw’uruzitiro rwa zinc n’imiterere y’ubuhinga. Nk'akarorero, uburemere bw'igice c'ivyuma gishushe-butegerezwa kuba Bunini canke bungana na 122g/m2. Ubushinwa bushira mu ngiro itegeko rya GB/T 33281-2016, rivuga ko uburebure bw’urusenga rw’intsinga rwo kwubaka butegerezwa kuba burengeye canke bungana na 12%. Ivyuma bimwe bimwe bikomeye bikoreshwa mu migambi y’ibikorwa remezo na vyo nyene bikozwe mu nsinga z’icuma zifise imirongo 500MPa kugira ngo bishobore gushitsa inkomezi zikenewe mu migambi minini.
Ibikorwa bisanzwe vy’urusenga rw’ivyuma vy’agaciro vyibanze cane ku bice bikurikira:
Injeniyeri y’ubwubatsi:Ni ikintu gikoreshwa cane mu bijanye n’ubwubatsi. Ibintu bifise umurongo w’urutsinga rwa 1,5mm n’ubunini bw’urusenga rwa 19mm birashobora gukoreshwa mu bikoresho vyo gukingira uruhome rw’inyuma no mu gutera ivyuma kugira ngo uruhome ntirusaduke; birashobora kandi gukoreshwa mu gusanura imiyoboro y’ubushuhe mu gihe co gushiramwo ubushuhe bwo munsi y’ubutaka no kwongerera inkomezi z’ibipande vy’ukwuzuza beton; mu migambi yo gushigikira ivyobo vy’umushinge, birashobora gukoreshwa hamwe n’imisumari y’ubutaka kugira ngo ubutaka ntibumeneke.
Ubuhinzi n’Ubworozi:Ibintu bifise umurongo w’urutsinga rwa 2.5mm n’uburebure bw’urusenga rwa 50mm×50mm akenshi bikoreshwa mu bibanza vy’inkoko n’inzitiro z’amatungo, bikaba bitanga umwuka n’uburinzi; mu mirima y’ivyamwa, irashobora gukoreshwa mu gukora urusenga rw’inyoni kugira ngo inyoni ntizitere ivyamwa no kugira ngo ingemwe zikingirwe n’ibikoko vyo mw’ishamba.
Inganda n’Ibikorwa remezo:Mu bijanye n’ubucukuzi bw’amabuye y’agaciro, bishobora gukoreshwa mu gukora urusenga rwo gusesagura ibice vy’amabuye y’agaciro; iki gikoresho kandi gikoreshwa cane ku bipande vy’urusenga vy’imirongo mu bibanza vy’ububiko, n’ibikoresho bifise umurongo w’urutsinga rwa 3mm bishobora kwikorera imizigo irenga 500kg/m2; mu migambi yo gukingira amabarabara n’ibiraro, birashobora gutuma ubutaka buhungabana, bikagabanya ugusenyuka kw’ubutaka n’ingorane zo gusenyuka kw’ubutaka.
Umutekano n’uburinzi: Bishobora gukoreshwa nk’uruzitiro rwo gukingira amabarabara n’ibibanza vy’itumanaho kugira ngo abakozi n’ibikoko bitagira akamaro ntibegere no kugira ngo ibikoresho bibe vyiza; birashobora kandi guhindurwa insenga zirwanya-ubusuma, ibikingi vy’inzira, n’ibindi kugira ngo bibe vyiza mu bibanza no mu bibanza vya bose.
Ikoreshwa ryinshi ry’urusenga rw’icuma gikozwe mu cuma gifitaniye isano cane n’ibiranga. Nk’umuhinguzi w’ibintu vy’umwuga, ishirahamwe ryacu riguma rikora ibintu bishasha kandi rinonosora ibiranga ibikorwa vyaryo kugira ngo rishobore gukoreshwa mu bikorwa vyinshi.
Corrosion-ishobora guhangana n’ugusenyuka kandi iramba: Igipande c’ivyuma gitandukanya umugozi w’icuma n’ikirere n’ubukonje. Igipande c’ivyuma gishobora gushika kuri 30-50μm, kandi gishobora kwihanganira amasaha arenga 500 y’ugupima umunyu ata n’umugese utukura. Ibintu vy’ivyuma bikoresheje ivyuma bishushe birashobora mbere kumara imyaka irenga 30 mu bihe bisanzwe, bikaba vyiza mu bidukikije bitandukanye bikomeye nk’ivyo hanze, ahantu hari ubukonje, n’aho hari aside/alkali.
Inkomezi nyinshi n’ubushobozi bwo guhangana n’ingaruka: Ahanini ikoresha ivyuma bifise carbone ntoya nka Q195 na Q235 nk’ibikoresho vy’ishimikiro, bifise inkomezi z’ugukomera zirengeye canke zingana na 380MPa, kandi irafise ubushobozi bwo guhinduranya neza, ishobora guhangana n’uguhinduka kw’ibintu iyo ishikiwe n’ingaruka zikomeye, kandi igahura n’ivya nkenerwa bitandukanye nk’uko {4
Igiciro kinini-ubushobozi n'ukwitaho vyoroshe: Igiciro kiri hasi cane y'urusenga rw'icuma kitagira ibara, gisaba hafi nta yindi kwitaho mu gihe co gukoresha, gusa ugusuzuma kworoshe mu bihe bitandukanye, bikagabanya cane igiciro c'ibikorwa vy'igihe kirekire-. Vyongeye, ivyo bintu ahanini bishirwa mu mizingo, ntibiremerera cane, birashobora gutemwa uko bikenewe, kandi biraryoshe gushiramwo no kubika.
Niba nawe ukeneye iki gikoresho c’ivyuma vy’umuringa, urashobora kuza muri sosiyete yacu kugira ngo uyisuzume, canke ukatubwira ivyo ukeneye tuzogukorera n’umutima wawe wose.
