威海Surface treatment technology of fiberglass board

Fiberglass board is a kind of high-performance, multi-functional building material, which is widely used, especially in the construction industry has been widely used. The surface treatment technology of fiberglass board has an important impact on the performance, aesthetics and durability of fiberglass board. Glass fiber board manufacturers will discuss the meaning of glass fiber board surface treatment, the classification of surface treatment, the way of surface treatment and the effect of surface treatment.

First, the significance of surface treatment

1. Improve the weathering resistance of fiberglass board

Although the fiberglass board has excellent performance, in the long-term use process, its surface is vulnerable to the influence of the external environment and lose stability. Surface treatment can improve the surface hardness and weathering resistance of fiberglass board, and reduce the surface loss and cracking.

2. Improve the durability of fiberglass board

The surface treatment can make the fiberglass board have better anti-corrosion, waterproof, anti-ultraviolet, wear resistance and other properties, so as to improve the durability and service life of the fiberglass board.

3. Improve the appearance of fiberglass board

The surface treatment can make the color of the surface of the fiberglass board more uniform, the surface luster more bright, and can provide a good primer for the surface coating of the fiberglass board. This can improve the beauty of the fiberglass board and better reflect the visual effect.

Second, the classification of glass fiber board surface treatment

1. Mechanical treatment

Mechanical treatment is a technology that deals with the surface of fiberglass board by mechanical force. In the process of processing, the surface of fiberglass board is stressed and deformed, so as to achieve the effect of surface treatment. This method usually uses tools such as grinding wheels, brushes, and wire brushes.

2. Physical processing

Physical treatment refers to a technology that uses physical methods to treat the surface of glass fiber board. For example, chemicals are used to dissolve the chemical film on the surface of the fiberglass board, thus making the surface harder. The main methods of physical treatment are sandblasting, painting and electrophoresis.

3. Chemical treatment

Chemical treatment is a technique that treats the surface of fiberglass board by using a chemical solution. In the chemical treatment process, the chemical composition of the surface of the fiberglass board will be changed, so as to achieve the desired treatment effect. Chemical treatment mainly includes fluorination treatment, pickling treatment and electrochemical treatment.

Third, the surface treatment

1. Sand blasting

Sandblasting is a mechanical treatment. In the sandblasting process, the sandblasting gun is used to impact the surface of the fiberglass board to remove the impurities on the surface and achieve the effect of frosting. The method is simple and easy, and does not change the environmental properties, adsorption properties and costs of fiberglass board.

2. Paint

Painting is also a form of physical treatment. In the surface treatment process, the surface of the fiberglass board is first coated with primer, then painted, and then the fiberglass board is put into the baking room for drying. Then apply varnish to give it a shiny surface. This method is commonly used in the surface treatment process of electrical products.

Step 3: Electrophoresis

Electrophoresis is a method of surface treatment by depositing colored particles in liquid on the surface of a material with opposite electrical polarity through electrochemical principles. In the surface treatment process, the fiberglass board is suspended in an electrophoresis tank, and the water-soluble pigments in the tank are electrolytically decomposed and adsorbed on the surface of the fiberglass board to form a coating.

Fourth, the effect of surface treatment

1. Bright and smooth

After surface treatment, the surface of the fiberglass board will become smoother and brighter. For example, the surface of the paint looks very flat, no pores, high gloss.

Step 2: Durable

The surface of the glass fiber board after surface treatment has the characteristics of high coverage and stability, and the glass fiber board after the surface is covered is more durable.

Step 3 Look good

In addition to durability and weathering resistance, the surface of the glass fiber board after surface treatment is more uniform, delicate, and more beautiful. For example, electrophoretic surface treatment can make fiberglass board have a smooth surface and increase the brightness of the color.

In short, surface treatment is a common treatment of fiberglass board, through surface treatment can improve the surface of fiberglass board, improve the performance of fiberglass board, beauty and durability, so that it is more widely used in the construction industry.
