Usually, air filter cotton filters out dust in the air to ensure fresh air. According to the different materials and filtration efficiency, filter cotton can be divided into three types: initial effect filter cotton, medium effect filter cotton, and effective filter cotton. Air filter cotton can be divided into four types: synthetic fiber filter cotton, non-woven fabric filter cotton, glass fiber filter cotton, and activated carbon filter cotton; With the improvement of people's awareness of health and environmental protection, and the increasing demand for precision manufacturing in the industrial field, the application areas of filter cotton are constantly expanding. So, let's learn about the application areas and production processes of air filter cotton together!

The air contains a large amount of dust particles such as dust, smoke, and sandstorms, which create sedimentation points; In precision instrument manufacturing, dust directly affects product quality; In industrial production, dust can increase the wear and tear of mechanical equipment components. Once inhaled, it can cause lung diseases and pose a threat to human health; During the painting process, dust mixed into the paint layer can reduce equipment performance and lifespan, causing damage to the ecological environment.

There are many downstream markets for air filter cotton, which is used in the electrical field, surface treatment, painting, and other aspects to prevent product defects caused by dust; In the field of precision equipment manufacturing, it can be used in air conditioning heat exchange systems to provide fresh air indoors while extending the lifespan of air conditioning; In the fields of automobiles and machinery manufacturing, it can prevent dust from interfering with drug efficacy; In the field of environmental protection, it can be used for the treatment of flue gas emissions from industries such as coal and steel, and in the biopharmaceutical industry that can provide a high-definition, clean, and pollution-free production environment for precision electronics, optical electronics, and others.

Air filter cotton is suitable for various industrial applications; For example, in the painting industry, electroplating industry, surface treatment, exhaust countermeasures, building ventilation, pollution prevention, public, air conditioning industry, household electrical industry, automotive industry, motorcycle manufacturing, electronics industry, watch industry, pharmaceutical factories, food industry, packaging materials, furniture industry, decoration engineering, etc., they are widely used and can also be added with frames to make filters.

Good air filter cotton is made of organic synthetic fibers with high elasticity, high tensile strength, and fracture resistance, which can prevent any fiber from falling off or leaking. If fiber shedding and shedding occur in the filter cotton used, it may be due to issues with the raw materials used and the manufacturing process. Made with effective and high-quality water-based resin rubber through multiple processing techniques such as impregnation. In addition, due to the increasing fiber density layer by layer, non-woven fabric or fiber mesh fabric is generally used for reinforcement on the windward side. Therefore, attention should be paid to the quality of materials and high-quality ones should be selected as much as possible.

The weight of air filtration cotton should reach 560-620 grams per square meter, and there may be some differences. It should be noted that if the thickness difference exceeds the normal range, the higher the weight, the better the quality. If the effect is good, the density is not enough, and the filtration effect is greatly reduced. It is also an abnormal situation that requires careful selection. Weight is not the standard for measurement.

Air filter cotton is divided into two types in terms of technology: surface spray glue and three-dimensional spray glue, so three-dimensional spray glue filter cotton has good filtering effect and long service life. If the adhesive amount is uneven, the viscosity is low, the adhesive quality is poor, and the dust and fiber adsorption effect is poor during the production process, the surface rubber filter cotton is coated and bonded on the surface during production, and the three-dimensional rubber filter cotton is coated and bonded on the inside, especially in the place of use. If it can meet the requirements of production technology and purification needs, such air purification filters are ideal. Hair shedding may occur. When sorting air purification filter cotton, attention should be paid to the above three aspects. In addition, users need to consider their actual needs.
