1. Whakataki o Q315NS maitai waikawa-ātete:
Waitohu: Q315NS
Ingoa Hua: Te rino atete waikawa whanariki mo te iti o te pāmahana te waikura ira hauhautanga
Paerewa Kaiwhakahaere: GB/T28907-2012
Ko te rahi, te ahua, te taumaha me te rerekee e whakaaetia ana o Q315NS me ū ki te GB/T709.

2. Whakamāramatanga o te rino ātete waikawa Q315NS:
Q315NS tikanga whakapuaki: Q-te reta tuatahi o te pinyin Hainamana o "qu" i roto i te kaha tuku;315—te rohe tuku iti o te maitai, i te MPa;NS—ko te reta tuatahi o te pinyin Hainamana o te "atete" me te "waikawa".Q315NS rino ātete waikawa e tohu ana ki te taapiri i etahi huānga whakakotahi ki te rino hei whakanui ake i te parenga ki te waikawa pungatara i hangaia e te whakakotahitanga o te whanariki trioxide me te wai i raro i te toma i te wa e pa ana te maitai ki te hau sulfuric (pērā i te tumere maitai kei roto te hau whakamomori).Te mahi waikura.

4. Nga taonga miihini o Q315NS waikawa-atete rino: te kaha tuku rauemi Ra MPa te kaha whakaroa Ra MPa i muri i te whati A%Q315NS≥315≥440≥22Q345NS≥345≥470≥20

5. Te parenga waikura o te rino-waikawa Q315NS:
E ai ki te tikanga whakamatautau i tohua i roto i te JB/T7901, ko te reiti waikura kaua e neke ake i te 10mm/a (0.89mg/cm²*h, 30% e pa ana ki te reiti waikura o Q235B i raro i nga tikanga o te pāmahana o te 20 ℃, he sulfuric. te kukū waikawa o te 20%, me te rumaki katoa mo te 24 haora);I raro i te ahua o te pāmahana 70 ℃ me te rumaki katoa mo te 24h, ko te reeti waikura toharite kaua e neke ake i te 250mm/a (22.4mg/cm²*h, 50% e pa ana ki te tere waikura Q235B).
