Glass clarifier

Abstract

The invention discloses a glass clarifier and belongs to the technical field of glass manufacturing. The glass clarifier is made with cerium carbonate and yttrium oxide; ammonium bicarbonate is used as a settling agent; crystal seed is added as an additive; glass clarifier base is prepared. The settling agent is added, cerium carbonate and yttrium oxide solid particles and the settling agent molecules form bridging connection, xi potential is reduced, and the solid particles grow bigger by absorbing settlement in the solution until growing into large particles; the glass clarifier has high bulk density and good settling property and provides better quality for glass products. Glass requires high transparency; as to trace colorants, such as iron, divalent iron can be oxidized into trivalentiron under the strong oxidation of the clarifier, maximum penetration rate of Fe3+ right matches with human eye sensitivity, and high transparency is visually acquired. The problem is solved that existing glass clarifiers have high toxicity and poor environmental friendliness and cannot provide improved mechanical properties of glass.

Description

technical field [0001] The invention belongs to the technical field of glass manufacture, and in particular relates to a glass clarifying agent. 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 produce gas or reduce the viscosity o...
