Abstract
The invention provides a raw material wetting agent used in a process of plate glass for a display and a preparation method, solving the technical problem of the enhancing of the mixture uniformity in a glass raw material. The wetting agent is prepared by the step of mixing organic acids. The organic acid mixture comprises the following compositions in percentage by weight: 50-68 percent of Cl8H32O2, 20-37 percent of C18H34O2, 2-10 percent of C16H32O2, 1-7 percent of C18H30O2, 0.6-6 percent of C18H36O2, 0.1-1 percent of C20H40O2 and the balance of organic impurity, wherein C18H30O2+C18H36O2+C20H40O2=4-10 percent. The wetting agent greatly enhances the mixture uniformity and has the advantages of high adhesion, little scattering quantity and weak condensability, thereby enhancing the quality of mixture.
Description
Technical field
The invention belongs to glass manufacturing area, relate to the former batching wetting agent and the preparation method that use in a kind of plate glass for display manufacture craft, particularly can improve the wetting agent of batching uniformity coefficient.
Background technology
On chemical physical property, necessary uniformity is if mix inhomogeneous with admixtion for glass, then the more part burn-off rate of lyotrope such as soda ash is fast, the more part of refractory compound, fusing are just relatively more difficult, even can fusing time be prolonged residual unfused quartz particles.So just destroy the homogeneity of glass, and easily produced defectives such as calculus, striped, bubble, and the more part of lyotrope, when contacting with pool wall, easily erosion of refractory also causes glass inhomogeneous.Particularly PDP glass melting temperature is higher than about general float glass 100 degree, and this has more quickened the erosion process of melting furnaces.But because various grain size of raw material differ bigger, moisture is different with material property, wants to reach to mix, and minimizing is dispersed, and is very difficult thing.
The method that domestic general employing adds water increases the adhesivity between each raw material, reach the uniformity coefficient requirement of compound, winter is because temperature is low, adds that soda ash and the saltcake in the compound still exists with the form of crystal water behind the water, cause the compound inequality, also do not reach processing requirement even add hot water.Reduction along with the material temperature produces new layering in the raw material course of conveying simultaneously, mixes and expects behind the furnace hopper because temperature rising moisture loss produces new layering again.Compound needs big energy when advancing behind the kiln moisture evaporation, has increased energy consumption like this, because part moisture evaporates in advance, compound still produces the serious phenomenon of dispersing in kiln, cause shortcomings such as checker obstruction, the erosion of kiln body simultaneously.
Summary of the invention
The objective of the invention is to improve the inhomogeneity technical barrier of compound in the frit in order to solve, the former batching wetting agent and the preparation method that use in a kind of plate glass for display manufacture craft have been designed, add water blended method with adding in the preparing glass charge in the alternative prior art of wetting agent of the present invention, and then improve the compound uniformity coefficient, significantly improve melting efficiency.
