Abstract

The invention relates to a glass refining agent and a preparation method thereof, and belongs to the field of the glass refining agents. Catalytic oxygen evolution is performed through catalyst additive release by gas; meanwhile, the assembly is formed with ferriporphyrin; the catalysis active center sites are increased; the catalysis process is promoted; water steam and glass melt take reaction at the molten high temperature; the viscosity and surface tension of the glass are reduced; the bubble discharge is promoted; a branched structure is formed through an extrusion foam discharge agent; the flowability of a refining agent is improved; substances with elastic structures and good mechanical performance form elastic deformation, so that the extrusion discharging of bubbles is further promoted; the glass crystallization is induced through light transmission nucleation additives; the light effect of the glass is improved, so that the transparency of the glass is improved; auxiliary additives are added in an auxiliary way to realize the coordination participation into a glass silica network structure; the softening point of the glass is improved; the better melting is realized. Theglass refining agent and the preparation method solve the problems that by using the existing glass refining agent, micro bubbles liable to occur on the glass plate surface, and flaws are caused.

Description

technical field [0001] The invention relates to the technical field of glass clarifiers, in particular to a glass clarifier and a preparation method thereof. Background technique [0002] Air bubbles formed by contaminants in the glass melt are called "air seeds". The existence of air seeds has an impact on the refractive index, density and light transmittance of glass. During the process of glass batch melting at high temperature to form glass, complex physical and chemical changes have taken place. Accompanied by these reactions and changes, a large amount of gas is released. The main sources of gas are: the gas entrained by the batch material and the gas adsorbed on the surface. The amount of this gas is insignificant compared with the gas generated by the decomposition of the batch material. Unless the batch material forms a large mass and does not melt away so that the gas cannot escape, this form of gas escapes through volatilization or evaporation at the early stag...
