Embodiment 2

[0019] In this example, the calcined lime mud treated in Example 1 is used as raw material to prepare glass fiber. The specific operation steps are as follows: (1) Weigh the raw materials according to the following proportions: 50 parts of pyrophyllite, 10 parts of leucolite, dolomite 6 parts of limestone, 10 parts of calcined white clay, 25 parts of kaolin, 7 parts of boronite and 6 parts of albite. Among them, the particle size of albite, dolomite, and calcined white mud is ≤100 mesh, that of boronite is ≤200 mesh, and that of kaolin, pyrophyllite, and leucolite is ≤325 mesh. (2) Send all kinds of raw materials into the pneumatic mixing and stirring sender, and stir evenly, and the uniformity is greater than 92%; (3) Send the uniformly mixed materials into the glass tank furnace for melting to obtain high-temperature glass liquid; melting temperature It is controlled within the range of 1600°C; the melting time is 72h; (4) After clarification and homogenization, the obtained...

Abstract

The invention discloses a method for producing fiberglass by using pulping and papermaking white mud. The method comprises the following steps that in the step of treating the pulping and papermaking white mud, water is added into the white mud to be stirred so as to be uniformly dispersed and diluted, after coarse and big particles are removed, filtering and condensation are carried out to obtain dewatering white mud; the dewatering white mud is dried and calcined at the temperature of 900 and 950 DEG C to obtain a white mud calcining matter; in the step of mixing the following components in parts by weight, the components including 50-60 parts of pyrophyllite, 8-10 parts of quartzitic sandstone, 5-8 parts of dolomite, 8-10 parts of white mud calcining matter, 15-25 parts of kaoline, 7-10 parts of borocalcite and 4-6 parts of albite are mixed; smelting at high temperature to prepare glass liquid and wiredrawing and molding to prepare the fiberglass. According to the method, the problems of environment pollution and land occupation caused by white mud land treatment are solved; and meanwhile, the white mud is subjected to resource utilization, so that exploitation and consumption of natural limestone resources in the fiberglass industry are reduced, the manufacturing cost of the fiberglass can be reduced, and the method has obvious environment benefit and economic benefit.

Description

technical field [0001] The invention relates to a method for processing and utilizing causticized lime mud recovered from pulping and papermaking alkali, and using it as a raw material for glass fiber production, which belongs to the technical field of glass fiber production, and in particular relates to a production method using pulping and papermaking lime mud. Fiberglass method. Background technique [0002] White mud is a kind of solid waste produced after chemical pulping wastewater (also called black liquor) is treated in an alkali recovery system. In order to prevent environmental pollution, the black liquor in the pulp mill is generally treated with the current mature alkali recovery technology, the organic matter in the black liquor is burned to use heat energy, and the caustic soda (NaOH) consumed in pulping can be recovered. The alkali recovery system treats 90% of the pollutants in the pulp mill, but also produces a large amount (about 0.8 tons of lime mud / 1 ton...
