Peb cov khoom
Zoo Frosted Milky Dawb Borosilicate iav Tubes
Milky dawb frosted silica iav quartz raj
1. Cov iav kub kub kuj tuaj yeem ua haujlwm hauv qab 1200 ° C tsis tu ncua, thiab lub sijhawm luv luv tuaj yeem ua haujlwm qis dua 1450 ° C, nws qhov muag muag yog 1650 ° C, thiab lub ntsiab lus melting yog 1650-1800 ° C.
2.Corrosion resistant, Tsuas yog hydrofluoric acid, Quartz raj tsis hnov mob nrog cov kua qaub thiab lub hauv paus tshwj tsis yog hydrofluoric acid.the stability yog 30 npaug ntawm cov ceramic, thiab 150 npaug ntawm stainless hlau.
3.Excellent thermal shock stability
4.High kis mus rau 85%
5. Hluav taws xob rwb thaiv tsev, nws yog 10000 zaug ntawm ib txwm iav.
