Icyiciro cya SPA-H ikirere cyicyuma, icyuma cya Corden
1. Ibisobanuro byoroshye:
SPA-Hikirere, bizwi kandi nk'icyuma cyangirika cyangiza ikirere, bivuga ubwoko buke-alloyibyuma bikomeye
ikubiyemo ibintu bike bivangavanze, igiciro gito, hamwe no kurwanya ruswa neza mukirere. Umuti nyamukuru
ibintu ni Cu, P, Cr, Ni, Si, Mn, V, RE, nibindi Mugihe cyo gukoresha ibyuma byikirere, firime yuzuye kandi ifatanye neza
Ibicuruzwa byangirika bizagenda buhoro buhoro hejuru kugirango birinde ogisijeni, amazi nibindi bitangazamakuru byangirika mu kirere
kurushaho kwangirika substrate, kuburyo igipimo cyo kwangirika kigabanuka cyane ugereranije nicyuma cya karubone. . Bitewe n'imbaraga zayo nyinshi kandi
igiciro cyumvikana, igiciro cyumusaruro kiri munsi cyane yicyuma. Ubuyobozi bukuru bwa SPA-H ni: JISG3125-2015.

4. Gusaba:
1) SPA-H nicyuma cyikirere cyo gutunganya ibikoresho, gukata no gusudira. SPA-H ikoreshwa cyane mubikoresho byubwato,
ibiraro by'ibyuma, amato n'ibigega kugirango birinde kwangirika kw'ikirere.
2) Icyuma cya SPA-H gikoreshwa cyane mugukora ibikoresho. Inganda zitwara kontineri zifite amateka arenze
Imyaka 50 kwisi. Imyaka 30 irashize, gutwara kontineri yigihugu cyanjye byari bikiri ubusa. Kuva ivugurura no gufungura, igihugu cyanjye
kubaka ibyambu no gutwara ibintu byakomeje gutera imbere. Cyane cyane mu myaka yashize, amahanga yahuye nayo
ibintu bya “kontineri imwe biragoye kuyibona.
5. Ihame ryo kurwanya ruswa ：
Iyo ibyuma bihuye nizuba ryumuyaga n umuyaga, kurwanya ruswa ni ngombwa cyane. Nyuma yo kongeramo fosifore, umuringa, chromium,
nikel nibindi bintu byerekana ibyuma, hazashyirwaho firime yuzuye kandi ikomeye yo gukingira hejuru yumuringa,
irashobora kugira uruhare runini rwo kurinda.
