What is the purpose of air filter cotton?

In today's socio-economic development process, the application of filters has been widely popularized, and different types of filtration devices are applied in different industries. Air filter cotton is one of many filtration devices, which not only has its own advantages and characteristics, but also what is the use of air filter cotton?

Air filter cotton can capture suspended solids or dust particles within 0.5um, so it can be used in the tail end filtration of filtration devices. The filter material used for air filter cotton is extremely fine glass fiber paper, and the cutting plate is formed by stretching aluminum foil plate, adhesive hard cardboard material, etc. The sealing agent uses high-quality polyurethane sealant, and the frame is made of stainless steel plate, galvanized steel plate, and aluminum profile.

Leak detection method for air filter cotton:

Because the types of air filter cotton belong to the category of centrifugal filters, it is necessary to master the corresponding leak detection methods to ensure the quality of air filter cotton before use. There are five common leak detection methods for air filter cotton, namely DOP method, sodium flame method, fluorescence method, welding smoke method, and particle counting method, and all five methods are common in the market.

The DOP method is mainly used to detect air filtration cotton sponge, which can heat the liquid state of DOP and generate steam. The steam will turn into water droplets under certain special conditions. After removing large or small water droplets, the remaining water droplets will enter the air duct to determine the filtration efficiency by detecting the turbidity of the gas sample.

The sodium flame method belongs to a more standardized detection method in the industry nowadays. This method can determine the actual effect of air filter cotton on corrosion-resistant filtration systems based on the chromaticity of the flame. The law of welding fumes is determined by the welding fumes to assess the filtering status of air filter cotton against welding fumes.

How often is the cotton filter washed?

There is often such a big time difference because everyone's living environment is different. If the natural environment is relatively clean and the machinery and equipment are not frequently used, the cotton filter cleaning operation is likely to take a long time to complete. But if the natural environment is harsh and the application is frequent, the frequency of cleaning the filter cotton is relatively high.

In addition, some cotton filters have unsatisfactory actual results even after being applied once or twice, and the dirt cannot be cleaned thoroughly. Don't use this type of filter cotton anymore. It should be replaced with a new one, just like the previous product, to make it easier for the machine equipment to be pushed forward.

Here we need to popularize to everyone that there are many types of filter cotton, such as polyester fiber fabric filter cotton, non fabric filter cotton, etc., which are common types.
