High borosilicate iav, nws yog ib yam uas tsis tshua muaj nqi, siab kub resistant, siab zog, siab hardness, siab transmittance thiab High Chemical stability tshwj xeeb iav khoom, piv nrog rau cov iav, uas tsis yog-tshuaj lom tshwm sim, nws txhua yam khoom, thermal stability. , dej tsis kam, alkali tsis kam, acid tsis kam thiab lwm yam khoom muaj zog ntau ntxiv, uas tuaj yeem siv dav hauv kev lag luam tshuaj, aerospace, tub rog, tsev neeg, tsev kho mob thiab lwm yam kev lag luam, tuaj yeem ua rau lub teeb, tableware, scaleplate, telescope, soj ntsuam qhov tshuab ntxhua khaub ncaws, microwave qhov cub tais, hnub ci dej rhaub thiab lwm yam khoom, muaj kev txhawb nqa zoo thiab cov txiaj ntsig kev sib raug zoo, cov iav zoo li no hauv peb lub teb chaws yog cov khoom siv hauv kev lag luam yog kev hloov pauv tshiab.
Lub linear expansion coefficient ntawm siab borosilicate iav yog 3.3 x 0.1 × 10-6 / K.Nws yog ib hom iav nrog sodium oxide (Na2O), boron oxide (B2O2) thiab silicon dioxide (SIO2) raws li cov khoom siv yooj yim.Cov ntsiab lus ntawm borosilicate hauv cov iav tivthaiv yog qhov siab, raws li: boron: 12.5 ~ 13.5%, silicon: 78 ~ 80%, yog li cov iav no hu ua siab borosilicate iav
High borosilicate iav yog tsim los ntawm kev siv cov khoom siv hluav taws xob ntawm iav ntawm qhov kub thiab txias, melting iav los ntawm cua sov hauv lub khob, thiab ua tiav los ntawm kev siv technology siab heev.Siv rau microwave qhov cub.,lub tog raj kheej tshuab ntxhua khaub ncaws tsom qhov rais thiab lwm yam kub-resistant teapot thiab teacup.
Lub cev thiab tshuaj lom neeg cov khoom ntawm siab borosilicate iav yog raws li nram no:
Silicon＞80%
Qhov ntsuas kub yog 520 ℃
Annealing kub 560 ℃
Lub softening kub yog 820 ℃
Kev ua haujlwm kub (104DPAS) yog 1220 ℃
Thermal expansion coefficient (20-300 ° C) 3.3 × 10-6K-1, yog li cov cua txias ceev thiab ceev kub ua hauj lwm yog superior.
Kub kam rau ua: 270 degrees
Qhov ceev (20 ℃)
