摘要
对玻璃配合料中硅灰石取代不同比例的石灰石进行X-射线衍射、粘度和澄清效果的研究,结果表明硅灰石可以显著降低能耗,降低玻璃的粘度,提高澄清的效果。从硅灰石的结构组成分析了其助熔的原因,计算出硅灰石取代石灰石后能耗由249.01kJ/mol降为131.35 kJ/mol,前者约为后者的1.88倍,从理论上证明了硅灰石的节能效果。
X - ray diffraction analysis, viscosity and substituted by wollastonite were investigated. Results refining of the glass in which the limestone was show that this substitution is of benefit to saving energy, reducing glass viscosity and also improving refining. The mechanism of fluxing effect of wollastonite was analyzed on the base of its structure. Calculation indicates that the energy consumeption decreases from 249. 01 kJ/mol down to 131. 35 kJ/mol due to the subsitution of limestone by wollastonite , i. e. energy consumption of original glass is 1.88 times higher than that substituted by wollastonite. It proves the energy - saving effect of the wollastonite in theory.
