Four Advantages of Glass Fiber Reinforced Plastic Negative Pressure Fan

The four major advantages of fiberglass negative pressure fans are that high-temperature air generates water vapor through the water curtain, which lowers the temperature and generates a large amount of negative ion oxygen, thereby improving the oxygen content in the workshop, effectively regulating the mood of staff, and improving work efficiency. 1. The fan housing is made of corrosion-resistant fiberglass, which is characterized by acid and alkali resistance, rust resistance, and long service life. The TPi6206 bearing is used as the rotating bearing. The bearing is processed by CNC to ensure good concentricity, and the shaft center is processed by external circle to ensure concentricity and smoothness, thereby ensuring the stability and durability of the entire bearing operation.

1. Low investment and low energy consumption. With the same cooling rate, the one-time investment is about one sixth of that of air conditioning, and the operating cost is about one tenth of that of air conditioning;

2. The air is fresh and moist. The air cleanliness can reach above 90-97%%;

3. High temperature air generates water vapor through the water curtain, which lowers the temperature and generates a large amount of negative ion oxygen, thereby increasing the oxygen content in the workshop, effectively regulating the mood of staff, and improving work efficiency.

4. Obvious effect and strong cooling. In summer, the temperature can be reduced by more than 5-15 degrees Celsius, and the higher the temperature, the greater the cooling range (indoor can be reduced to about 25 degrees Celsius);

Negative pressure fans are currently the most commonly used ventilation fans in factories, and the main outer frame materials of mainstream negative pressure fans are fiberglass and galvanized sheet materials. What are the advantages of fiberglass negative pressure fans compared to galvanized sheet materials? Let’s take a look together.

1. Lightweight and high-strength

The relative density ranges from 1.5 to 2.0, which is only 1/4 to 1/5 of carbon steel, but the tensile strength is close to or even exceeds that of carbon steel, and the specific strength can be compared to high-grade alloy steel. Therefore, it has achieved remarkable results in aviation, rockets, spacecraft, high-pressure vessels, and other products that require weight reduction.

2. Good corrosion resistance

Fiberglass reinforced plastic is a good corrosion resistant material that has good resistance to atmospheric, water, general concentrations of acids, alkalis, salts, as well as various oils and solvents. It has been applied to various aspects of chemical anti-corrosion and is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.

3. Good electrical performance

It is an excellent insulation material used to manufacture insulators. It can still protect good dielectric properties at high frequencies. Microwave transmission is good, so it is widely used in radar radomes

4. Low thermal conductivity

At room temperature, it ranges from 1.25 to 1.67kJ/(m · h · K), with only 1/100 to 1/1000 of metal fiberglass safety helmets [2]/1000, making it an excellent insulation material. Under instantaneous ultra-high temperature conditions, it is an ideal thermal protection and ablation resistant material that can protect spacecraft from high-speed airflow erosion above 2000 ℃.

The advantages of fiberglass fans are as follows:

1. Strong relative density

The relative density ranges from 1.5 to 2.0, which is only 1/4 to 1/5 of carbon steel, but the tensile strength is close to or even exceeds that of carbon steel, and the specific strength can be compared to high-grade alloy steel. Therefore, it has achieved remarkable results in aviation, rockets, spacecraft, high-pressure vessels, and other products that require weight reduction. The tensile, bending, and compressive strength of some epoxy FRP can all reach over 400Mpa. The density, strength, and specific strength of some materials.

2. Good corrosion resistance.

FRP is a good corrosion resistant material that has good resistance to atmospheric, water, and general concentrations of acids, alkalis, salts, as well as various oils and solvents. It has been applied to various aspects of chemical anti-corrosion and is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.

3. Good electrical performance

It is an excellent insulation material used to manufacture insulators. It can still protect good dielectric properties at high frequencies.

4. Good thermal performance

FRP has a low thermal conductivity, ranging from 1.25 to 1.67kJ/(m · h · K) at room temperature, only 1/100 to 1/1000 of metal, making it an excellent insulation material. It is an ideal material for thermal protection and erosion resistance under instantaneous ultra-high temperature conditions.

5. Good designability

Various structural products can be flexibly designed according to needs to meet usage requirements, resulting in a good overall product.

6. Excellent craftsmanship

The process is simple and can be formed in one go, with outstanding economic effects, especially for products with complex shapes and small quantities that are difficult to form, highlighting its technological superiority. The surface treatment is simple and can replicate the effects of many materials.
