Glass fiber sheet As a common building material, it has excellent heat insulation, corrosion resistance and acid and alkali resistance, and is widely used in the construction field. The process technology for manufacturing glass fiber sheet will be introduced in detail below.

1. Raw material preparation

The first step in manufacturing glass fiber sheet is to prepare the required raw materials. These raw materials include glass fiber, resin and additives. The glass fiber can be in the form of filament or staple, and the resin can be epoxy resin or phenolic resin. The type of additives depends on the specific use needs.

2. Fiber stretching

The glass fiber is stretched through a wire drawing machine to form a slender fiber. The key to this step is to control the drawing speed and temperature to obtain high-quality glass fiber sheets. The stretched fiber will be collected in the fiber collection tank for subsequent treatment.

3. Fiber coating

Fiber coating refers to immersing the drawn glass fiber into the resin to make the fiber absorb the resin evenly. The purpose of this step is to fully combine resin and fiber to enhance the strength and resistance of glass fiber sheet. Coating is usually carried out by dipping, roller coating or spraying, among which dipping is the most common method.

4. Fiber layout

The coated fibers need to be arranged to ensure the direction and distribution of fibers are uniform. The arrangement process is usually carried out manually or automatically, and the coated fibers are arranged in a crisscross manner according to the design requirements.

5. Fiber curing

The arranged fiber sheet needs to be cured to form a stable structure. The main method of this step is to cure the fiber sheet by heating or light curing to make the chemical reaction in the resin occur. Heat curing needs to be carried out under appropriate temperature and time conditions, while UV curing needs to use ultraviolet or visible light radiation.

6. Post treatment

The cured glass fiber sheet also needs some post-treatment work to improve its quality and appearance. Common post-treatment includes cutting, trimming, polishing and polishing. These steps can further improve the flatness and smoothness of the glass fiber sheet.

7. Inspection and packaging

The manufactured glass fiber sheet needs to be strictly inspected to ensure its quality meets the requirements. Inspection mainly includes appearance inspection, dimension measurement and performance test. After passing the inspection, the glass fiber sheet shall be packaged for storage and transportation.

To sum up, the process technology for manufacturing glass fiber sheet includes the steps of raw material preparation, fiber stretching, fiber coating, fiber layout, fiber curing, post-treatment, inspection and packaging. The reasonable operation and control of these steps can ensure the production of high-quality glass fiber sheets and provide excellent thermal insulation materials for the construction field.
