Embodiment 1

[0011] Embodiment 1: First, the mica raw material is broken into mica raw pulp through a pulper, and the mica raw pulp is sent to the pulp making tank, and then 34 kg of water is filled in a container, and the bone glue with a viscosity of 8 ° E is added to the water, and the added The quality of bone glue is 15% of the water quality, and the bone glue is dissolved in water by heating with 70°C steam, and the insoluble impurities are filtered out through a 90-mesh screen to form a bone glue solution, and then the bone glue solution and defoamer (JY-801) are added to the In the paper-making pulp tank of mica raw pulp, the amount of bone glue solution added is 4‰ of the total mass of mica raw pulp in the paper-making pulp tank, and the amount of defoaming agent is 0.005% of the total mass of mica raw pulp in the paper-making pulp tank, so that the mica raw pulp Mix evenly with bone glue solution and defoamer, and finally pass mica paper machine to form and dry to produce qualifie...

Embodiment 2

[0012] Embodiment 2: First, the mica raw material is broken into mica raw pulp through a pulping machine, and the mica raw pulp is sent to the pulp making tank, and then 35 kg of water is filled in a container, and the bone glue with a viscosity of 10 ° E is added to the water, and the added The quality of bone glue is 17.5% of the water quality, and the bone glue is dissolved in water by heating with 80°C steam, and the insoluble impurities are filtered out through a 90-mesh screen to form a bone glue solution, and then the bone glue solution and defoamer are added to the papermaking machine containing mica puree In the slurry tank, the amount of bone glue solution added is 5‰ of the total mass of mica pulp in the papermaking pulp tank, and the amount of defoaming agent is 0.01% of the total mass of mica pulp in the papermaking pulp tank. The foaming agent is mixed evenly, and finally it is shaped by a mica paper machine and dried to produce qualified mica paper.

Embodiment 3

[0013] Embodiment 3: First, the mica raw material is broken into mica raw pulp through a pulping machine, and the mica raw pulp is sent to the pulp making tank, and then 36 kg of water is filled in a container, and the bone glue with a viscosity of 12 ° E is added to the water, and the added The quality of bone glue is 20% of the water quality, and the bone glue is dissolved in water by heating with 90°C steam, and the insoluble impurities are filtered through a 90-mesh screen to form a bone glue solution, and then the bone glue solution and defoamer (JY-801) are added to the In the paper-making pulp tank of mica raw pulp, the amount of bone glue solution added is 6‰ of the total mass of mica raw pulp in the paper-making pulp tank, and the amount of defoaming agent is 0.015% of the total mass of mica raw pulp in the paper-making pulp tank, so that the mica raw pulp Mix evenly with bone glue solution and defoamer, and finally pass through the 1092 cylinder mica paper machine on ...

Abstract

The invention provides a production method of sizing mica paper. Firstly, mica raw materials are crushed to mica raw pulp through a pulping machine, the mica raw pulp is conveyed to a papermaking pulp tank, and the papermaking pulp tank is filled with water through a container, bone glue with viscosity between 8 DEG C and 12 DEG C is added to the water, the volume of the added bone glue is 15% to 20% of the water mass, the water is heated by steam with the temperature between 70 DEG C and 90 DEG C so as to enable the bone glue to be dissolved in the water, insoluble impurities are filtered and bone glue solution is made, the bone glue solution and antifoaming agents are added to the papermaking pulp tank containing the mica raw pulp, the volume of the added bone glue solution is 4%. to 6%. of the total mass of the mica raw pulp in the papermaking pulp tank, the volume of the antifoaming agents is 0.005% to 0.015% of the total mass of the mica raw pulp in the papermaking pulp tank, the mica raw pulp, the bone glue solution and the antifoaming agents are mixed evenly, and eventually the mica paper is made in a papermaking molding mode through a mica paper machine, the mica paper is dried and the standard mica paper is produced. According to the production method of the sizing mica paper, adhesive force on the surface of lodicule in the production method of the mica paper can be improved, tensile force of the mica paper in the process of production is increased and the purpose of winding the paper easily is achieved.

Description

technical field [0001] The invention relates to a production technology of mica paper, in particular to a production method of sizing mica paper. Background technique [0002] Mica is a natural mineral with excellent high insulation, anti-corona, acid and alkali resistance, and anti-radiation effects. Mica is generally used in the electrical industry and military products to make insulating materials for cables and large-scale electromechanical equipment. For example, it is pressed into commutator mica plates of different thicknesses, and processed into stamping parts to be used as the main insulating parts of electrical equipment such as generators and motors. Mica capacitors are used in aerospace, navigation, and radar, and have a wide range of applications. They are indispensable high insulation, acid and alkali resistance, and heat insulation materials in today's world. [0003] Studies have shown that mica is a natural mineral that does not contain harmful substances t...
