The quality of air is directly related to our physical and mental health, and it is equally important in the field of industrial production. Everyone knows that there will be a lot of dust in the air we breathe, and this dust will be emitted everywhere with the air. Fortunately, with air filter cotton, it can greatly reduce the dust content in the air we breathe, so as to achieve the effect of purifying the air. So how to choose and replace the air filter cotton?
1. Grasp the main influencing factors to choose, such as high temperature gas, flammable dust, etc.
2.The filtration performance of filter cotton should meet the conditions and special requirements in the production process;
3. Gas temperature: The temperature of dust-containing gas is a very important factor. Generally, the gas lower than 130 ℃ is called normal temperature gas, and the gas higher than 130 ℃ is called high temperature gas, so it can be divided into the selection of filter material. For these two types, namely normal temperature filter material and high temperature filter material;
4. Humidity of the gas: Dust-containing gases can be divided into three types according to their relative humidity. When the relative humidity is below 30%, it is a dry gas, and between 30% and 80% is a general state. Above 80% It is a high-humidity gas. For high-humidity gas, condensation will occur when the gas is cooled when it is at a high temperature. This will cause the surface of the filter bag to foul and block, and it is also easy to corrode the material. This is also what we need to choose when choosing. Pay attention
5. Select filter materials with longer service life as much as possible, which can not only save operating costs, but also meet the discharge requirements of standards;
6, price comparison, beware of some bad businesses to take advantage of price concessions, sell some inferior products, when choosing, shop around, do not covet small and cheap.
Method of choosing:
First, look at the material
High-quality air filter cotton is made of organic synthetic fibers with high elasticity, high tensile strength and break resistance. It is manufactured with high-quality high-quality water-based resin glue and processed through dipping and other processes. It is reinforced with high-performance polyester fabric or fiber mesh to prevent any fibers from falling off and leaking. If the filter cotton you use appears fiber shedding and hair loss, it may be a problem of the raw materials and manufacturing process of the filter cotton.
The weight of filter cotton should be 560-620 grams per square meter. The higher the weight, the better the quality, and the better the effect; if the weight is insufficient, the density is not enough, and the filtering effect is greatly reduced. Some manufacturers on the market in order to save Cost, cut corners, so when you buy filter cotton, do more comparisons, choose high-quality manufacturers with weight and credibility, don't just try to be cheap.
Third, the gel content
Filter cotton is divided into two types: surface spray glue and three-dimensional spray glue. Surface glue filter cotton is coated with glue on the surface during production, and three-dimensional glue filter cotton is coated with glue on the inside. Therefore, the three-dimensional sprayed filter cotton has better effect and longer service life. If the amount of glue is not uniform, the viscosity is small, the quality of the glue is not good, and the adsorption effect of dust and fibers is poor, the phenomenon of hair loss and slag may occur.
How to choose and replace the air filter cotton? Seeing this, I believe everyone is a bit brow! In order to avoid unnecessary trouble, you must have a certain understanding of the air filter cotton before choosing, so that you can choose the applicable air Filter cotton to avoid blind choices!
