Igipimo Gishya Gituma Umuriro Udashira ku Bikoresho Bitari Iby'Ibyuma

Amabwiriza y’Igihugu agenga amagare y’amashanyarazi “Ibisobanuro by’umutekano ku magare y’amashanyarazi” (GB 17761-2024), verisiyo ivuguruye yasohotse ku mugaragaro kandi ishyirwa mu bikorwa guhera ku ya 1 Nzeri 2025, isimbura iy’ayari asanzweho (GB17761-2018).

Amabwiriza mashya ya “Tekiniki ku Mutekano w’Amagare y’Amashanyarazi” (GB 17761-2024) ashyiraho amabwiriza akomeye ku mikorere y’ibikoresho bitari iby’icyuma biri mu modoka.Uretse imiyoboro y'amashanyarazi n'ibice by'amashanyarazi bihujwe bigomba kugera ku rwego rwa UL94 V-0 nk'uko biteganywa mu 2018, iri hame rishya rinavuga ko igice cy'amashanyarazi kigomba kugera ku rwego rwa UL94 V-0, mu gihe imitako yoroshye, imyenda, uruhu, insinga z'amashanyarazi, n'ingero nto zoroshye gupfunyika bigomba kugera ku rwego rwo hejuru rudakoresha umuriro. Iri hinduka rigamije kongera umutekano w'amagare y'amashanyarazi mu bihe bikomeye nko mu nkongi z'umuriro.

Igipimo Gishya ku Bikoresho Bitari Iby'Ibyuma / Ni ibihe bisabwa byihariye kugira ngo habeho kurwanya inkongi no kudakoresha umuriro?

6.4.1 Ibisabwa ku bigabanya inkongi n'inkongi z'umuriro

Ibikoresho bitari iby'icyuma bikoreshwa mu magare y'amashanyarazi byujuje ibi bikurikira kugira ngo birwane n'inkongi kandi bitinde umuriro.

• a) Imikorere yo gutwika ibikoresho bitari iby'icyuma biri mu nsinga zose z'amashanyarazi n'ibice byazo by'amashanyarazi bihujwe (nk'insinga zo gusharija, swichi z'amashanyarazi, ibikoresho birinda insinga ngufi, insinga z'amashanyarazi, insinga, nibindi, uretse insinga) bigomba kubahiriza ibisabwa ku rwego rwa V-0 muri GB/T5169.16.
• b) Ibikoresho by'umusego ukozwe mu buryo bwa elastic (nk'ibikoresho byuzuye ifuro mu ntebe) bigomba kuzuza ibisabwa mu miterere y'umuriro nk'uko bigaragara mu mbonerahamwe ya 2 ya GB38262-2019 ku bikoresho by'umusego ukozwe mu buryo bwa elastic.
• c) Igihe cyo gutwika ibikoresho by'imyenda bitari iby'icyuma (nk'ibipfundikizo by'intebe) kigomba kuba ≤ 15s, igihe cyo gushyushya umwotsi kigomba kuba ≤ 30s, uburebure bw'ibyangiritse bugomba kuba ≤ 200mm, naho igipimo cya ogisijeni kigomba kuba ≥ 26.0%.
• d) Ibikoresho by'uruhu bitari iby'icyuma (nk'uruhu rutwikiriye intebe, nibindi) bigomba kuzuza ibisabwa ku miterere y'ibikoresho by'uruhu (ku ntebe) nk'uko bigaragara mu mbonerahamwe ya 2 ya GB382622019.
• e) Urwego rw'imikorere y'ibikoresho bitari iby'icyuma (nk'ibice bya bateri) bihuye neza n'agapaki k'ibati rugomba kuzuza ibisabwa ku rwego rwa V-0 muri GB/T5169.16.
• f) Insinga zose z'amashanyarazi zigomba kugira umucanwa uhagaze wa ≤425 mm.
• g) Uburyo bwo gutwika bw'ibindi bikoresho bitari ibyuma (nk'ibice by'imitako, ibirinda ibishingwe, nibindi, ariko hatarimo amapine) bugomba kuba bwujuje ibisabwa ku rwego rwa V-1 muri GB/T5169.16. Ku bipimo byoroheje bishobora kunama n'ibipimo byijimye ariko ntibika umuriro iyo bihuye n'umuriro, ubushobozi bwo gutwika bwabyo bugomba kuba bwujuje ibisabwa ku rwego rwa VTM-1 muri GB/T40302.

Sichuan Taifeng nk'umutanga serivisi w'umwuga wibanda ku bushakashatsi n'iterambere, umusaruro, no kugurisha ibintu bigabanya umuriro, dufite ubwoko butandukanye bw'ibicuruzwa bya ammonium polyphosphate (APP)

TF-201: bakunda gukoresha irangi rituma umuriro udashira

TF-211/TF-212: bakunda gusiga imyenda

TF303/TF-303S: Ishobora gushonga mu mazi, ikunda gukoreshwa mu kuvoma no mu kugabanya umuriro w'imbaho, fibreboard, impapuro, imyenda, imigozi y'imigano, n'ibindi.

TF-241: ikunda polyolefin (nka PP, PE, PBS) na rubber.

Ibikoresho bya Taifeng bya Ammonium Polyphosphate bidakoresha umuriro wa halogen byiteguye, murakaza neza kutwandikira.
