Qhov txawv ntawm siab borosilicate iav thiab cov khoom iav zoo tib yam

Neighborosilicate iav, tseem hu ua borosilicate iav, yog ib hom iav uas yog tsim los ntawm kev ntxiv boron oxide rau cov iav sib xyaw ua ke. Qhov sib ntxiv no ua rau cov iav tiv taus kev ntxhov siab thiab thermal shock, uas yog vim li cas nws feem ntau siv hauv kev sim thiab kev siv hauv kev lag luam. Hauv qhov sib piv, cov khoom siv iav zoo tib yam tsis muaj boron oxide thiab yog li ntawd ntau dua rau thermal stress thiab breakage.

Lwm qhov sib txawv ntawm cov iav nyob sib ze thiab cov khoom iav zoo tib yam yog lawv qhov pom tseeb thiab pob tshab. Neighborosilicate iav khoom muaj qib siab dua ntawm pob tshab thiab pom tseeb piv rau cov iav zoo tib yam. Qhov no yog vim qhov qis qis ntawm impurities thiab npuas hauv cov iav nyob ze, uas muab nws qhov zoo tshaj plaws kho qhov muag.

Thaum kawg, cov khoom siv iav nyob sib ze kuj tseem muaj zog dua li cov khoom iav zoo tib yam. Qhov no yog vim hais tias cov iav nyob sib ze muaj qis dua coefficient ntawm thermal expansion, uas txhais tau tias nws tsis nthuav los yog cog lus ntau npaum li qhov kub thiab txias. Raws li qhov tshwm sim, cov iav nyob sib ze tsis tshua muaj kev tawg lossis tawg thaum raug hloov pauv sai hauv qhov kub thiab txias.

Zuag qhia tag nrho, cov iav nyob sib ze yog hom iav zoo dua piv rau cov khoom iav zoo tib yam vim nws cov thermal tsis kam, clarity, thiab durability.
