Types of air filter materials

The air filter we mentioned in life is actually composed of air filter material and outer frame. So what kind of filter materials do filter manufacturers generally use for filters? Let's take everyone to announce one by one! 1. Synthetic fiber Synthetic fiber filter cotton can completely replace the non-woven fabric and glass fiber covering the full range of primary, medium and high-efficiency filter products in the general filtration environment. It is an emerging filter material and the main development direction of filter materials in the future. Using (polyester fiber) as the main raw material, abbreviation: PET, polyester fiber is made of polyethylene terephthalate, also known as synthetic fiber or polyester. The name of the industry is: chemical fiber, chemical fiber is divided into large chemical fiber and small chemical fiber, large chemical fiber refers to polyester fiber produced with high-quality PET chips; small chemical fiber refers to some small and medium-sized manufacturers use low quality recycled materials to regenerate PET chips Production of fiber. Compared with the filter material of the same level, it has the advantages of low resistance, light weight, large capacity, environmental protection and moderate price. 2. Non-woven fabric The scientific name polyester fiber, commonly known as non-woven fabric, has the technical characteristics of widespread use, technical maturity, and good stability. It is a typical filter material for primary and medium-efficiency plate and bag filters in my country. The manufacturing process is made by melt blowing, needle punching, spunlacing, spunbonding and other processes through multiple processes. Compared with other filter materials of the same level, it has stable quality, large dust holding capacity, strong humidity resistance, long service life, and economical. Durability and other advantages. Non-woven fabric is also the earliest applied filter material. The technology is mature and the production cost is low. Due to the continuous progress of technology in recent years, the emergence of composite non-woven fabrics has greatly improved the low-cost image of non-woven fabrics. Efficient. At the same time, the composite non-woven filter material can also be used for filtering in places with relatively high air cleanliness. 3. Glass fiber The glass fiber filter media is mainly made of various glass fibers with different thickness and length by special processing technology. Glass fiber is characterized by its stable performance, high temperature resistance, high efficiency, large capacity and long service life. And in some special environments, only glass fiber can do the job. It is widely used in primary effect filters, high temperature resistant filters and high efficiency filters of general ventilation systems, in places and environments with high requirements for air filtration. 4. Activated carbon Activated carbon can also be used as a filter material. The characteristic of activated carbon is to remove odor in the air. Activated carbon filter cotton refers to the synthetic fiber undergoing carbon immersion and gum treatment. The function of activated carbon is to remove odor, so the filtration efficiency is not emphasized. In use, it is generally used with independent primary and intermediate efficiency filters. The above four are filter cotton commonly used by filter manufacturers. Generally, the filter material used in the primary effect filter is the primary effect cotton, that is, synthetic fiber filter cotton; the medium efficiency filter generally uses non-woven fabric or glass fiber filter cotton; The filter materials used in high-efficiency filters are PP, glass fiber, PTFE, etc.

What role does patio cotton play in the spray booth?

   In daily life, many daily necessities will have a variety of colors, and how do these colors attach to it? This must mention the spray booth. Every item is sprayed and sprayed. Our daily life Among them, the ones that are exposed to more are mobile phones. The glass panels of Huawei mobile phones are bright and smooth. The patio cotton above the ceiling plays a big role.

   After the outdoor fresh air is dedusted through the primary effect filter cotton at the air inlet, it is sent into the plant by the fan to make the indoor air smooth. It seems very simple, but it is not. If you want to do this, you need to make use of your own advantages. There are 3 advantages.    Patio cotton    1.The patio cotton is processed by a high-performance hot-melt method made of organic synthetic fibers that are resistant to breakage; the incremental structure adopts a multi-layer progressive encryption technology, that is, the fiber density toward the pure air gradually increases, higher filtration efficiency, can According to the size of the dust, it is blocked at different density levels, which can accommodate more dust more effectively.    2. The air exit surface of the patio cotton is particularly dense, and a layer of checkered mesh is added to strengthen the setting. This structure not only keeps the filter material with high filtration effect and high dust capacity, but also extends the service life.    To ensure good air quality, due to the relatively low resistance of the filter material itself, it can also save system operating costs.    3. The filter material of the filter cotton is fully dipped, so it can prevent any fibers from falling off and leaking, and even if the system is in a state of vibration or temperature instability, this filter material can also filter out all particles larger than 5um; filter material There are full viscosity, surface viscosity, dry treatment for customers to choose.    The painting room patio cotton is designed for the baking room and the painting room. It is only used for the filtering of the end of the spraying. Its professionalism is not worse than that of any kind of filter cotton.
