Whakataki Hangarau

3.3 Ko te karaehe borosilicate teitei te mea tino pai rawa atu o te ao ka taea te whakamahi ki te hanga taputapu patu matū, te paipa paipa me te taputapu karaihe kua whakamahia e te taiwhanga.3.3 te karaehe borosilicate teitei he poto mo te karaehe borosilicate me te whakarea roha i te (3.3±0.1）×10-6/K-1, e kiia ana ko te karaihe Pyex i te ao.

Ko nga whakaritenga o te paerewa o te ao IS03587: ko te whakauru karaihe me te taputapu karaihe e whakamahia ana mo nga taputapu matū me tango te 3.3 karaihe borosilicate teitei.

Ko te paipa karaihe me nga whakaurunga kei roto i te Kamupene Nantong Sanjing ka mau katoa te karaehe borosilicate o te ao 3.3 mo te hanga me te hanga.

Te kounga o te wera

Ko te karaehe he kaikawe kino, he mea pakarukaru hoki, engari he rereke te karaehe borosilicate 3.3 mo ona waahanga matū kei roto 12.7% o te B2O3 e tino pai ake ana te pumau o te waiariki.

IS03587 nga korero:

Mo te karaehe borosilicate teitei me te diameter <Φ100mm, kaore i teitei ake i te 120 ℃ tona pāmahana wera-atete;

Mo te karaehe borosilicate teitei me te diameter> Φ100mm, karekau he teitei ake i te 110 ℃ te pāmahana o te wera-atete.

I raro i te pehanga tonu （20 ℃-100 ℃）
