What is the production process of Black Fiberglass Tissue Facing?

1. Raw material preparation
The main raw materials of Black Fiberglass Tissue Facing are glass fiber and resin. Glass fiber is usually E-glass or C-glass, which has the characteristics of high strength, high modulus, corrosion resistance, etc. Resin is used as a binder to bond the glass fibers together to form a facial paper with specific properties.

Before production, the glass fiber needs to be pretreated, such as degreasing and dust removal, to ensure the purity and uniformity of the glass fiber. At the same time, the resin also needs to be mixed and stirred to adjust its viscosity and curing speed to meet the requirements of the production process.

2. Fiber dispersion and arrangement
The pretreated glass fiber is fed into the fiber disperser, and the glass fiber is dispersed into uniform fiber bundles by a high-speed rotating dispersion disk. Then, the fiber bundles are arranged into an orderly fiber mesh through a special arrangement device. This step is crucial to the fiber distribution uniformity and finished product performance of Black Fiberglass Tissue Facing.

3. Resin impregnation and curing
The arranged fiber mesh enters the resin impregnation tank, and the resin is evenly infiltrated into the fiber mesh by impregnation and extrusion. The impregnated fiber mesh is pre-cured on the conveyor belt, and the resin is initially cured by heating and pressurizing to form a semi-finished product with a certain strength.

The temperature and pressure of pre-curing need to be precisely controlled to ensure that the curing degree of the resin and the strength of the fiber mesh meet the requirements. At the same time, it is also necessary to pay attention to prevent the deformation and wrinkling of the fiber mesh during the pre-curing process.

4. Surface treatment and dyeing
The pre-cured Black Fiberglass Tissue Facing semi-finished product enters the surface treatment process, and the burrs and unevenness on the surface are removed by sanding, polishing, etc. to improve the surface quality of the product. Then, according to customer needs, the semi-finished product is dyed to give it a black or other color appearance.

In the dyeing process, it is necessary to select environmentally friendly and weather-resistant dyes, and strictly control the dyeing temperature and time to ensure the dyeing effect and the environmental performance of the product.

5. Finished product cutting and packaging
The semi-finished product after dyeing is cut into the required specifications and sizes by a cutting machine, and then sent to the packaging process for packaging. During the packaging process, care should be taken to prevent scratches, deformation and contamination of the product to ensure the quality and appearance of the product.

At the same time, packaging materials also need to choose environmentally friendly and durable materials, such as plastic films, corrugated boxes, etc., to protect the safety of the product during transportation and storage.

6. Quality inspection and delivery
Before the finished product is packaged, the product needs to be quality inspected, including appearance quality, physical properties, chemical properties and other aspects. Through inspection, problems in the production process can be discovered and corrected in time to ensure that the quality of the product meets customer requirements.

After the quality inspection is qualified, the product can be shipped out of the factory for sale. Before leaving the factory, the product needs to be marked and recorded so that customers can trace and query relevant information about the product.

7. Environmental protection treatment
During the entire Black Fiberglass Tissue Facing production process, attention should also be paid to environmental protection treatment. For example, wastewater and waste gas generated during the pretreatment of glass fiber need to be treated before discharge; waste gas generated during resin impregnation and curing also needs to be collected and treated to prevent harm to the environment and human body.

At the same time, waste generated during the production process also needs to be classified and processed. For example, waste fibers and waste resins can be recycled or entrusted to professional organizations for processing.
