Abstract

The invention discloses a composite glass clarifying agent, which belongs to the field of the glass production. The composite glass clarifying agent is prepared from the raw materials such as acrylamide and sodium dimethyl diacrylamide sulfonate and can be slowly expanded after being heated, and can form a wrapping and supporting effect for a netted structure formed by silicate and SiO2 in a glasssystem, polymer microspheres comprise partial gas in the preparation process, in the application process, the partial gas overflows rapidly, so that the dispersity is good, and a better bubble inhibition and removal effect can be achieved; and polyether is introduced into the organic silicon, no only can the hydrophilic group but also the oleophylic group be provided, by introducing the paraffinand microcrystalline paraffin, a long-chain aliphatic compound can be introduced, the silicon tetrahydride can be rapidly hydrolyzed into orthosilicic acid and hydrogen under an alkaline condition, generation of other bubbles can be prevented, the secondary bubbles can be further prevented, and a better bubble eliminating effect can be achieved. By adopting the composite glass clarifying agent, the problem that the conventional glass clarifying agent is poor in bubble removal efficiency.

Description

technical field [0001] The invention belongs to the field of glass manufacturing, and in particular relates to a clarifier for composite glass. Background technique [0002] Glass clarifying agent belongs to one of the products of glass manufacturing technology. Bubbles in glass are one of the main defects of glass products, and the existence of a large number of bubbles seriously affects the quality of glass. Glass clarifier is an important auxiliary raw material in glass production. Most clarifiers can vaporize or decompose to release gas at high temperature, so that the partial pressure of gas in the glass liquid is greater than the partial pressure of gas in the small bubbles in the equilibrium state, thus The balance among the kiln gas, glass liquid and small bubbles is broken, so that the small bubbles become the atmosphere and run out of the glass liquid to achieve the effect of clarification. [0003] Any raw material that can generate gas or reduce the viscosity o...
