Using quartz sand, limestone, dolomite and other natural mineral as the main raw material, cooperate with some soda, borax etc chemical raw materials melting into glass. 采用石英砂、石灰石、白云石等天然矿石为主要原料,配合一些纯碱、硼砂等化工原料熔成玻璃。
The effects of borax glass inhibitor content on oxidation resistance of C/ C composites was studied by oxidation experiments. The oxidation mechanism was analyzed on the basis of SEM results. 采用氧化烧蚀试验研究了改性剂硼玻璃含量对C/C复合材料抗氧化性能的影响,通过扫描电镜(SEM)观察分析了其抗氧化机理。
Introducing of alkali metal oxide, borax, cryolite facilitates melt and accelerates the refining and homogenizing of glass, so they can indirectly prevent the colorant from evaporating. 碱金属氧化物、冰晶石、B2O3主要起助熔作用,降低玻璃熔制温度,加速玻璃的澄清和均化,间接防止着色剂硒和硫的挥发。
At present, the domestic purification technologies of industrial boric acid and borax have a certain gap for preparation of nuclear grade boric acid and borax for high-borosilicate glass. Impurity content is obviously higher than standard or required. 目前国内对工业硼酸、硼砂的纯化技术距离制备核工业级硼酸和高硼硅酸盐玻璃用硼砂还有一定差距,杂质含量达不到要求。
