Glass microfiber cotton and filter paper

Abstract

The invention provides glass microfiber cotton and filter paper, the glass microfiber cotton comprises the following components in parts by weight: 50-65.5 parts of SiO2, 1.5-10 parts of Al2O3, 7-16 parts of B2O3, 8-21 parts of RO, 2-15 parts of MO and 2-7 parts of ZnO, and RO is the sum of Li2O, Na2O and K2O in the glass microfiber cotton; and MO is the sum of MgO, CaO and BaO in the glass microfiber cotton component. The glass microfiber cotton has good tensile strength and tensile strength after irradiation and small fiber diameter distribution standard deviation, slag ball content and acid soaking weight loss, and the tensile strength, the tensile strength after irradiation, the fiber diameter distribution standard deviation, the slag ball content and the acid soaking weight loss have good balance. The glass microfiber cotton is excellent in comprehensive performance and has good chemical stability and thermal stability.

Description

technical field [0001] The invention relates to the field of inorganic non-metallic materials, in particular to a glass microfiber cotton and filter paper. Background technique [0002] Glass microfiber cotton is an inorganic non-metallic material with excellent performance. It has the characteristics of insulation, heat resistance, flame retardancy, and high strength. It is widely used in filter materials, protective materials, separation materials (coalescence), shielding materials, thermal insulation and sound insulation. and other fields. [0003] According to different applications, glass microfiber wool needs to be set with different properties, such as tensile strength, fiber diameter distribution, shot content and acid and alkali resistance, etc. In general, in order to increase the tensile strength of glass microfiber wool, people often achieve it by reducing the standard deviation of fiber distribution, but this will lead to an increase in the content of slag ball...

AI Technical Summary

Problems solved by technology

In general, in order to increase the tensile strength of glass microfiber wool, people often achieve it by reducing the standard deviation of fiber distribution, but this will lead to an increase in the content of slag balls in the glass microfiber wool, an increase in the weight loss of acid-resistant immersion, and may also affect The increase in strength loss rate after irradiation is not what we want. Therefore, people are eager to have glass microfiber wool with balanced properties to meet the needs of production and life.
