Capillary and Crystalization Strength of Glass Batch Components

The attraction of glass particles simulating quartz sand grains for capillary rings of aqueous solutions of sodium sulfate and carbonate of various concentrations is experimentally investigated.

As water evaporates and the solution becomes saturated, additional cohesion of solid particles is registered, which is caused by the formation of crystallization contacts.

影响玻璃配合料质量的温度因素

从配合料温度的角度分析影响配合料质量的环节和因素。     

Rapid Heating of a Glass Batch in an Advanced Glass Melter

In the advanced glass melter the glass batch is rapidly heated to glass melting temperature by convecting the batch in the combusting gas. Total heating time for the batch, which has particle sizes in the 10- to 150-μm range, is of the order of 50 ms. A computer model has been developed to predict thermal history of the particles including temperature and other phenomena such as calcination and fusion. It also predicts particle velocity and acceleration in the gas and inertial separation of particles from the gas at the target. The model was developed to help in choosing particle sizes of different batch ingredients, defining the operating envelope and optimizing system performance. Experimental measurements of heated batch temperature show good agreement with numerical calculations.     

A Model for Optimizing Glass Batch Compositions
