Qhov txawv ntawm dej qab zib-txiv qaub iav thiab borosilicate iav
Mar 20, 2024
Sodium calcium iav thiab high-boron silicon iav, tseem hu ua borosilicate iav, yog ob hom iav nrog cov khoom sib txawv thiab kev siv. Nov yog qee qhov sib txawv tseem ceeb ntawm lawv:
Muaj pes tsawg leeg: Sodium calcium iav feem ntau yog tsim los ntawm sodium oxide (Na2O) thiab calcium oxide (CaO), nrog rau silicon dioxide (SiO2). Ntawm qhov tod tes, borosilicate iav muaj boron oxide (B2O3) ntxiv rau silicon dioxide. Lub xub ntiag ntawm boron oxide hauv borosilicate iav muab nws cov khoom tshwj xeeb.
Cov khoom siv thermal: Borosilicate iav muaj qhov sib npaug qis ntawm thermal expansion, txhais tau tias nws tuaj yeem tiv taus qhov kub hloov pauv sai yam tsis muaj qhov tawg. Cov cuab yeej no ua rau nws tsim nyog rau chav kuaj iav, cookware, thiab lwm yam kev siv uas yuav tsum tau tiv thaiv thermal shock. Sodium calcium iav, thaum tseem muaj qee qhov thermal kuj, tej zaum yuav tsis muaj tib theem ntawm thermal shock kuj zoo li borosilicate iav.
Tshuaj tiv thaiv: Borosilicate iav yog cov tshuaj tiv thaiv corrosion los ntawm acids, bases, thiab ntau lwm yam tshuaj. Nws yog feem ntau siv nyob rau hauv cov chaw soj nstuam tshuaj thiab kev lag luam chaw uas tsis kam mus rau tshuaj tua kab mob tseem ceeb heev. Sodium calcium iav, txawm hais tias feem ntau chemically resistant, tej zaum yuav tsawg resistant rau tej yam aggressive chemicals piv rau borosilicate iav.
Cov khoom siv kho qhov muag: Sodium calcium iav nthuav tawm cov khoom siv kho qhov muag zoo, ua rau nws tsim nyog rau kev siv kho qhov muag xws li lo ntsiab muag thiab qhov rais. Borosilicate iav kuj muaj qhov pom kev pom zoo, tab sis nws qhov txiaj ntsig tseem ceeb nyob hauv nws cov thermal thiab tshuaj tiv thaiv ntau dua li qhov khoom siv kho qhov muag.
Daim ntaub ntawv: Vim nws zoo heev thermal poob siab tsis kam thiab chemical durability, borosilicate iav yog feem ntau siv nyob rau hauv lub chav kuaj iav, cookware, tshuaj ntim khoom, teeb pom kev zoo khoom, thiab ntau yam kev siv. Sodium calcium iav feem ntau yog ua haujlwm hauv cov khoom siv kho qhov muag, qhov rais, thiab cov iav ntim uas nws cov khoom kho qhov muag tseem ceeb dua.
Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm sodium calcium iav thiab high-boron silicon iav (borosilicate iav) nyob rau hauv lawv cov muaj pes tsawg leeg, thermal zog, tshuaj tiv thaiv, kho qhov muag, thiab kev siv. Borosilicate iav yog lub npe hu rau nws superior thermal thiab tshuaj tiv thaiv, thaum sodium calcium iav muaj nuj nqis rau nws cov khoom kho qhov muag.
