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 karaihe borosilicate me te whakarea roha i (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 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 3.3 o te ao 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 mahana-atete wera;
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 ℃)
