What are the four types of primary filter cotton?

Generally speaking, filter cotton refers to primary air filter cotton, which can filter dust in the air and ensure the cleanliness of the air. So, what are the four types of primary filter cotton?

What are the four types of primary filter cotton?

1. Glass fiber filter cotton: Glass fiber filter cotton is mainly made of various thicknesses and lengths of glass fibers through special processing technology. The characteristics of glass fiber are stable performance, high temperature resistance, high efficiency, large capacity, and long service life. In some special cases, only fiberglass can be competent. Widely used in places and environments with high requirements for air filtration, such as primary filters, high-temperature resistant filters, high-efficiency filters, etc. in general ventilation systems.

2. Synthetic fiber filter cotton: The main raw material for synthetic fiber filter cotton is polyester fiber, which is poly (p-xylene) or polyester. Polyester has excellent elasticity, dimensional stability, good electrical insulation, sun resistance, friction resistance, mold resistance, chemical resistance, weak acid and alkali resistance. In general filtration environments, it can completely replace non-woven fabrics and glass fibers to cover a full range of coarse, medium, and high-efficiency filtration products. It is a new type of filter material and the main development direction of future filter materials. Compared with other filter media of the same level, it has the advantages of low resistance, light weight, large capacity, environmental protection (incineration), and moderate price.

3. Non woven filter cotton: scientific name polyester fiber, commonly known as non-woven fabric. Non woven fabrics have technical characteristics such as wide applicability, mature technology, and good stability. It is currently a typical filter material for plate and bag dust collectors in China. The manufacturing process adopts techniques such as melt blown, needle punched, hydroentangled, and spunbonded. Compared with other filter materials of the same grade, it has the advantages of stable quality, large dust holding capacity, strong moisture resistance, long service life, and economic durability. Non woven fabric is also an early used filtering material with mature technology and low production cost.

4. Activated carbon filter cotton: The characteristic of activated carbon is to remove odors from the air. Activated carbon filter cotton refers to synthetic fibers impregnated and gelatinized with carbon. Because the function of activated carbon is to remove odors, the filtration efficiency is not emphasized. In use, it is generally necessary to use independent primary, medium, and small filter cartridges in combination.

What is the function of primary filter cotton?

Mainly used for pre filtration in purification systems, it is a commonly used and widely applied filtering material in air purification filtration, mainly used to filter 5-micron particulate dust and suspended solids in the atmosphere.

What are the characteristics of primary filter cotton?

1. The primary filter cotton mainly filters dust particles larger than 5 millimeters;

2. The initial filtration cotton is made of high-performance and high-strength incremental structural synthetic fibers;

3. It has the characteristics of high dust holding capacity, low resistance, and strong flame retardancy;

4. Long service life, can be used multiple times after cleaning, economical and practical;

5. Can withstand 100 degrees;

6. The filter cotton meets the fire classification standards;

7. Paper and metal frames are used to manufacture filter materials for filters, such as plate filters, washable plate filters, paper frame filters, and bag filters.
