摘要
市场已有的料器玻璃料、钠钙玻璃料、铂组玻璃等、一般为载币玻璃,这些材料成本高,因它的形状系数大,80-100×10-7,熔点低,软化点低300-400℃,热稳定性能差,耐热温度120℃左右就爆型。化学稳定性差,长期在潮气下,表面会出现小斑点、变松和发毛等,为“风化现象”。粘皮也差,加工性能较差,长时间熔经,容易出现失透现象,故不能制作精细复杂的工艺品。
The glasses on the market almost are soft glasses, such as Glassware glass, soda-lime glass and so on. They have many characters such as high cost, large coefficient of expansion 80-100×10^-7. low melting point low soften point 300-400℃, the margin of sudden lemperature change about 120℃. bad chemical stability, easy to be weathered, low viscosity, difficult to be processed and so on.
