1. Kumenyekanisha ibyuma birwanya aside Q315NS:
Ikirango: Q315NS
Izina ryibicuruzwa: Acide sulfurique irwanya ibyuma byubushyuhe buke bwikime
Igipimo ngenderwaho: GB / T28907-2012
Ingano, imiterere, uburemere hamwe no gutandukana kwa Q315NS bigomba kubahiriza GB / T709.

2. Ibisobanuro bya Q315NS ibyuma birwanya aside:
Q315NS uburyo bwo kwerekana: Q - inyuguti ya mbere ya pinyin yo mu gishinwa ya “qu” mu mbaraga zitanga umusaruro;315 - umusaruro muke wibyuma, muri MPa;NS - inyuguti ya mbere ya pinyine yo mu Bushinwa ya “irwanya” na “aside”.Q315NS ibyuma birwanya aside bivuga kwongeramo umubare munini wibintu bivanga mubyuma kugirango byongere imbaraga zo kurwanya aside sulfurike iterwa no guhuza triuxide ya sulfure namazi munsi yikime mugihe ibyuma bihuye na gaze ya sulfuru (nka a chimney ibyuma birimo gaze ya gaze).Imikorere ya ruswa.

3. Ibigize imiti ya Q315NS ibyuma birwanya aside:
Ibikoresho CSiMnPSCrCuSbQ345NS≤0.15≤0.55≤1.20≤0.035≤0.0350.30-1.200.20-0.50≤0.15

4. Ibikoresho bya mashini ya Q315NS ibyuma birwanya aside: imbaraga zitanga umusaruro Ra MPa imbaraga zingana Ra MPa kuramba nyuma yo kuvunika A% Q315NS≥315≥440≥22Q345NS≥345≥470≥20

5. Kurwanya ruswa ya Q315NS ibyuma birwanya aside:
Ukurikije uburyo bwikizamini bwerekanwe muri JB / T7901, igipimo cya ruswa ntikirenza 10mm / a (0.89mg / cm² * h, 30% ugereranije n’ikigereranyo cya ruswa ya Q235B mu gihe cy'ubushyuhe bwa 20 ℃, sulfurique acide yibice 20%, hamwe no kwibiza byuzuye mumasaha 24);Ukurikije ubushyuhe 70 ℃ no kwibizwa byuzuye kuri 24h, ikigereranyo cyo kwangirika ntikirenga 250mm / a (22.4mg / cm² * h, 50% ugereranije na Q235B igipimo cya ruswa).
