Icyuma kitagira umugese cyo mu rwego rw'ibiribwa ni iki?

Icyuma kidafunze cyo mu rwego rwo hejuru rw'ibiribwa bivuga ibikoresho by'icyuma kidafunze bikurikiza amahame y'Igihugu y'Igihugu cy'Ubushinwa / Amabwiriza y'Isuku ku Bikoresho by'Ibyuma bidafunze GB 9684-88. Ingano yacyo ya lisansi na chromium ni nke cyane ugereranyije n'iy'icyuma gidafunze rusange.

Iyo ibyuma biremereye ibikoresho by'icyuma kitagira umugese bijya mu bikorwa birengeje urugero, bishobora gushyira ubuzima bw'abantu mu kaga. Kubera iyo mpamvu, Amabwiriza y'Igihugu agenga umutekano w'ibiribwa ya “Stainless Steel Products” (GB9684-2011) yashyizeho amahame akomeye agenga igwa ry'ibyuma biremereye bitandukanye nka chromium, cadmium, nickel, na lisade mu bikoresho byo guteka. Impamvu imwe ni uko ubwiyongere bw'ingano ya manganese mu byuma bitagira umugese, habaho gutakaza imikorere nko kurwanya ingese no kurwanya ingese mu gikoni. Iyo ingano ya manganese igeze ku gaciro runaka, iki gicuruzwa ntigishobora gukoreshwa nk'igikoni cyangwa ntikishobora kwitwa igikoni gitagira umugese. Ariko nubwo ingano ya manganese nyinshi, muri rusange nta ngaruka ku buzima. 304 stainless steel ni icyuma gisanzwe cyane, cyitwa kandi 18-8 stainless steel mu nganda. Indwara yacyo ya 304 stainless steel ni nziza kurusha 430 stainless steel, irwanya ingese nyinshi, kandi irwanya ubushyuhe bwinshi, ikora neza, bityo ikoreshwa cyane mu nganda, mu mitako yo mu nzu, no mu nganda z'ubuvuzi, urugero, ibikoresho byo ku meza bya steel stainless steel, ubwiherero, ibikoresho byo mu gikoni.

Kugira ngo icyuma kidashonga kigumane ubukana bwacyo bwo kwangirika, icyuma kigomba kuba kirimo chromium irenga 17% na nikeli irenga 8%. Ugereranije, icyuma kidashonga cya 201, 202 (kizwi nka icyuma gifite manganese nyinshi) gikoreshwa mu nganda kandi ntigishobora gukoreshwa nk'ibikoresho byo ku meza, kuko: Ingano ya manganese irenze urugero, ikoreshwa ryinshi rya manganese mu mubiri w'umuntu rishobora kwangiza uturemangingo tw'imitsi.

Mu buzima bwa buri munsi, dufite amahirwe menshi yo gukora ku bikoresho by'icyuma kidashonga, kandi amasafuriya y'amashanyarazi akoresha icyuma kidashonga ni amwe muri yo. Biragoye gutandukanya ayo ari "201″? Ni ayahe ari "304″?"

Kugira ngo hamenyekane ibi bikoresho bitandukanye by'icyuma kidashonga, uburyo bukoreshwa muri laboratwari ahanini ni ukumenya imiterere y'ibintu. Hari itandukaniro rinini mu miterere y'icyuma mu bikoresho bitandukanye by'icyuma kidashonga. Ku bakoresha basanzwe, ubu buryo ni ubw'umwuga cyane kandi ntibukwiriye, kandi bukwiriye cyane ni ugukoresha igikoresho cyo gupima ingano ya manganese ya 304. Gushaka gusa kumanuka hejuru kugira ngo umenye niba ibikoresho bifite ingano ya manganese irenze urugero, bityo umenye ingano ya manganese ya 201 na 304. Kandi ku itandukaniro riri hagati y'icyuma kidashonga gisanzwe cya 304 n'icyuma kidashonga gisanzwe, hakenewe isuzuma rirambuye rya laboratwari kugira ngo umenye itandukaniro. Ariko tugomba kumenya ko imiterere y'icyuma kidashonga gisanzwe ari cyo gikomeye cyane, mu gihe icyuma kidashonga gikoreshwa mu nganda cyoroshye cyane.

Ibikoresho byujuje icyemezo cya GB9684 cy’igihugu kandi bishobora gukora ku biribwa nta ngaruka mbi ku mubiri. Ibyuma bitanduye bya GB9864 ni ibikoresho by’icyuma bitanduye byujuje icyemezo cya GB9684 cy’igihugu, bityo icyuma kitanduye cya GB9864 ni ibikoresho bitanduye byo mu rwego rw’ibiribwa. Muri icyo gihe, icyitwa 304 stainless steel ntabwo gisabwa kwemezwa n’icyiciro cya GB9684 cy’igihugu. Ibyuma bitanduye bya 304 ntabwo bingana n’iby’icyuma bitanduye byo mu rwego rw’ibiribwa. Ibyuma bitanduye bya 304 ntabwo bikoreshwa gusa mu bikoresho byo mu gikoni ahubwo binakoreshwa cyane mu nganda. Mu gihe cyo kugura, ibicuruzwa bisanzwe bizaba byanditseho "food grade 304 stainless steel" ku buso no mu rukuta rw’imbere rw’ibicuruzwa, kandi ibicuruzwa byanditseho "food grade-GB9684" biratekanye cyane.
