Filtration accuracy and efficiency of DPA paint mist filter cotton

The painting process needs to be used in many industries. The traditional extensive painting technology does not pay attention to the large amount of overspray fog and organic waste gas produced in the painting process, and it is even discharged into the atmosphere at the beginning. With the national requirements for environmental protection and people's awareness of environmental protection, this extensive treatment method has been eliminated, The paint mist treatment device and waste gas treatment device with rapid changes came into being. Paint mist treatment is not only an essential link in the painting process, but also a very important link, which will directly affect the production efficiency and the impact on the environment. Next, let's talk about a popular paint mist filter material in recent years - DPA paint mist filter cotton.

The full name of DPA is deep pocket arrestor, which is called DPA filter cotton. It takes the traditional filter cotton as the base material and forms a diamond pocket surface after processing, which improves the interception of paint mist.



DPA paint mist filter cotton is suitable for two-component solvent based paint and water-based paint μ The interception rate of paint mist particles above M can reach 100%, that of paint mist particles above 1 micron can reach 99.8%, and that of paint mist particles above 5 microns can reach 84%.



DPA filter cotton can be used not only as paint mist filter material, but also as bag filter in the process of waste gas treatment.



Compared with the traditional paint mist filter material, it has the advantages of excellent self-supporting ability, higher filtration accuracy and efficiency, larger dust capacity, longer service life and so on. And it can be burned directly to minimize environmental pollution.



Although the price is higher than the traditional paint mist filter material when it is replaced for the first time, its service life is 3-4 times that of the traditional paint mist filter material. Therefore, in comparison, it will bring higher production efficiency to the enterprise, reduce material and labor costs, and become the best choice for paint mist treatment in the future painting industry.
