Problems solved by technology

However, these methods have not been applied on a large scale, and the main problems are: the processing cost is too high, the income is small, and there is no promotion value; the consumption of lime mud is small, and the actual feasibility is small; the refining technology of lime mud is not mature enough, and its quality is still low. It cannot meet the requirements of many industries, and further r

Abstract

The invention discloses a method for producing glass fiber by using pulping and paper-making white mud. Raw materials comprise 18-23 parts of white mud calcined powder, 33-38 parts of pyrophyllite, 5-8 parts of dolomite, 5-8 parts of colemanite, 25-30 parts of quartzitic sandstone, 8-10 parts of kaolin, 1.8-2 parts of albite, 2.5-2.9 parts of fluorite, and 0.4-0.6 parts of a composite clarifying agent. The production method comprises the following steps: the raw materials are well mixed according to the ratio, and are melted; and the mixture is drawn, such that the glass fiber is obtained. According to the invention, white mud is adopted as a glass fiber production main raw material. White mud open storage can be reduced through comprehensive utilization; white mud environment pollution can be reduced; white mud can be turned from waste into a valuable matter; and produced glass fiber has higher strength.

Description

technical field [0001] The invention relates to the technical field of glass fiber preparation, in particular to a method for producing glass fiber by using white mud for pulping and papermaking. Background technique [0002] In the process of chemical pulping and papermaking, a large amount of black liquor will be produced. These black liquors contain a large number of substances harmful to the environment and cannot be directly discharged into the environment. The state stipulates that they must be treated before they can be discharged. [0003] In order to reduce environmental pollution, the black liquor produced by chemical pulping is processed by relatively mature alkali recovery technology, which burns the organic matter in the black liquor to use heat energy, and recovers the alkali consumed by pulping. The alkali recovery system treats 90% of the pollutants in the chemical pulp mill, but at the same time it also produces a certain amount of solid waste white mud. Th...
