Fiberglass board, also known as fiberglass board (FR-4), is a new type of board composed of fiberglass material and high heat resistance composite material. It has various excellent physical and chemical properties and is widely used in multiple fields. The following is a detailed introduction to fiberglass board:
1、 Material characteristics
High temperature resistance: Fiberglass board has good high temperature resistance and can maintain structural stability at high temperatures ranging from 150 ℃ to 260 ℃, making it less prone to deformation and cracking.
Corrosion resistance: This board can resist the erosion of chemical substances such as acid and alkali, and will not deform or crack during long-term use.
Wear resistance: The surface is smooth and flat, with good wear resistance, long service life, and strong durability.
Good insulation performance: Fiberglass board has excellent electrical insulation properties and is suitable for products with high-performance electronic insulation requirements.
Lightweight and High Strength: With light density and weight, it has high structural strength and excellent properties such as tensile, bending, and impact resistance.
Good processability: easy to process into various shapes and sizes to meet different application needs.
2、 Application Fields
Construction industry: Fiberglass panels are widely used in the construction industry, such as cooling towers, building structures, indoor equipment and decorative parts, fiberglass plates, decorative panels, and solar energy utilization devices. Its excellent high temperature resistance, corrosion resistance, and wear resistance enable buildings to maintain stability and safety even in high temperature, humid, or corrosive environments.
Chemical industry: In the field of chemical engineering, fiberglass board is used to manufacture corrosion-resistant pipelines, corrosion-resistant conveying pumps and their accessories, grilles, ventilation facilities, as well as wastewater and sewage treatment equipment. Its excellent corrosion resistance ensures the long-term stable operation of chemical equipment.
Automotive and transportation industry: In the automotive field, fiberglass panels are widely used in body, interior, sound insulation materials, and other aspects. Its lightweight and high-strength characteristics help reduce the overall weight of the car, improve fuel efficiency and safety. In the field of transportation, such as road signs, isolation piers, and highway guardrails in highway construction, fiberglass panels are also commonly used.
Electrical and electronic industry: Fiberglass board has been widely used in the electrical and electronic industry due to its excellent insulation performance and high temperature resistance. Used for manufacturing PCB test stands, insulation partitions for electrical equipment, insulation pads, transformer insulation components, motor insulation components, etc.
3、 Production process
The production process of fiberglass board mainly includes steps such as raw material processing, melting, drawing, winding, weaving, and composite. The raw materials mainly include ores such as pyrophyllite, quartz sand, limestone, etc. After high-temperature melting, glass liquid is formed, and then glass fiber cloth is made through processes such as drawing, winding, and weaving. Finally, composite materials such as glass fiber cloth and resin are laminated into sheets under high temperature and high pressure.
4、 Environmental Protection and Safety
Fiberglass board meets environmental protection requirements during production and use, and does not contain harmful asbestos components to the human body. At the same time, it has excellent flame retardant properties and is not easy to burn in a fire, which helps reduce fire losses.
In summary, fiberglass board has become one of the indispensable materials in modern industry due to its excellent physical and chemical properties and wide range of applications.
