Embodiment 1

[0026] Such as Figure 1-2 Shown, a kind of low expansion coefficient glass fiber cloth desizing method of the present invention, comprises the following steps:

[0027] Step 1: Prepare the glass fiber gray cloth, the glass fiber cloth enters the water tank through the guide roller, and the organic matter on the surface of the glass fiber gray cloth is dissolved in hot water;

[0028] Step 2: Drum washing, the glass fiber gray cloth enters the water tank through the guide roller and is transported on the outer surface of the drum. The drum runs at a high speed driven by the motor to further impact the organic matter in the glass fiber gray cloth;

[0029] Step 3: Drying the glass fiber gray cloth, drying the glass fiber cloth after drum washing, removing the surface moisture of the glass fiber gray cloth, and winding the glass fiber cloth onto the desizing roller;

[0030] Step 4: BH sintering, the glass fiber gray cloth on the desizing roller is placed in a BH sintering furn...

Abstract

The invention discloses a desizing method for glass fiber cloth with a low expansion coefficient, and belongs to the technical field of glass fiber production. The desizing operation of the glass fiber cloth can be realized, glass fiber grey cloth on a desizing roller is placed in a BH smoldering furnace for smoldering, organic matters on the surface are further removed, and a sectional heating curve is set in the BH smoldering furnace for heating; and the organic matters on the surface of the glass fiber cloth are removed, and meanwhile, the tensile strength of the glass fiber cloth is not damaged. The technical development requirements of chip carriers in high-end industries such as aerospace, national defense military industry and supercomputers are met. The problems in the prior art are solved.

Description

technical field [0001] The invention relates to a method for desizing glass fiber cloth with a low expansion coefficient, and belongs to the technical field of glass fiber production. Background technique [0002] Electronic glass fiber with low expansion coefficient is a high-performance glass fiber for electronic packaging materials, mainly used as carrier material for chips, with high tensile strength, high elastic modulus, good impact resistance, good chemical stability, and fatigue resistance Good performance, high temperature resistance and other excellent properties, can be widely used in aerospace, aviation, weapons, ships, chemical industry and other electronic information industry chips that have strict requirements on the performance of composite materials. With the rapid development of intelligence and informatization in the electronic information industry, the market demand for high-strength, high-modulus and low-expansion coefficient electronic glass fibers is ...
