Equipment for continuous acid leaching treatment of high silica glass fiber cloth

Abstract

The invention discloses equipment for continuous acid leaching treatment of high silica glass fiber cloth. The equipment comprises an acid leaching slot; the acid leaching slot comprises a presoaking acid slot, a thermal acid slot I, a thermal acid slot II and a thermal acid slot III; the glass fiber cloth arranged on an unwinding machine enters the presoaking acid slot, the thermal acid slot I, the thermal acid slot II, the thermal acid slot III, a water washing slot I, a water washing slot II and a water washing slot III in sequence by a cloth feeding machine, pickling and washing are finished, the glass fiber cloth is dried and flattened by drying and flattening equipment, and is wound by a winding machine beside the drying and flattening equipment, and the production line operation is finished. The equipment is a piece of production line equipment, the content of SiO2 in the glass fiber cloth can be improved from 70% to be over 96% by controlling the process parameters through the process steps, the temperature resistance performance of grey cloth is improved to 100 DEG C, the continuous production line acid leaching production efficiency is high, the SiO2 content of obtained grey cloth is stable, the comprehensive performance of the product is greatly improved, and benefits are increased for an enterprise.

Description

technical field [0001] The invention relates to acid leaching treatment equipment, in particular to equipment for continuous acid leaching treatment of high silica glass fiber cloth, and belongs to the technical field of mechanical equipment. Background technique [0002] In recent years, with the changes in the international situation and the great emphasis on anti-terrorism, the fire protection of landmark buildings and high-rise buildings has been paid special attention. This has formed a market with a large demand for glass fiber cloth with advantages such as high temperature resistance, fire prevention, heat insulation, and insulation. In the past two decades, with the development of industrial technology and the revolutionary breakthrough of material science, the application fields and demands of high temperature resistant cloth have been continuously developed, and the market prospect is very broad. [0003] High temperature resistant glass fiber cloth is named accor...

AI Technical Summary

Problems solved by technology

In the follow-up, a separate process is required to wash and dry it. Since the intermittent equipment cannot meet the higher requirements for high temperature resistance of glass fiber cloth, the silica content in the treated gray cloth can only reach 90%. Poor, especially the high temperature resistance cannot be guaranteed, and the intermittent pickling process is discontinuous, resulting in unstable silicon content of the obtained product, which is difficult to meet the needs of large-scale production
