Txoj kev kos iav hlaws dai
Khoom piav qhia
iav hlaws yog ib yam tshiab ntawm cov khoom siv dav siv thiab cov khoom tshwj xeeb tsim nyob rau xyoo tas los no.Cov khoom yog ua los ntawm borosilicate raw cov ntaub ntawv los ntawm high-tech ua.Nws yog ib tug me me iav hlaws nrog uniform particle loj.Cov khoom muaj qhov zoo ntawm lub teeb yuag, tsis tshua muaj thermal conductivity, siab zog, zoo tshuaj stability, xav txog thiab lwm yam.Cov tshuaj muaj pes tsawg leeg: SiO2> 67%, Cao> 8.0%, MgO> 2.5%, Na2O14%, Al2O3 0.5-2.0, Fe2O3 >0.15, lwm yam 2.0%;Lub ntiajteb txawj nqus tshwj xeeb: 2.4-2.6 g / cm3;Qhov tsos: du, puag ncig, pob tshab iav tsis muaj impurities;Rounding tus nqi: ≥85%;Cov khoom sib nqus yuav tsum tsis pub tshaj 0.1% ntawm cov khoom hnyav;Cov ntsiab lus ntawm npuas hauv iav hlaws yog tsawg dua 10%;Nws tsis muaj cov khoom siv silicone.
