Structure of filter element:
High strength, no pollution, no burr, no chemical reaction of the inner skeleton;
The internal and external supporting network should have sufficient strength, no pollution, no burr, no chemical reaction;
Inner and outer lining paper should have high passing ability, high tensile strength, should use long fiber, no shedding, no chemical reaction material.
High performance filter material should be made of inert fiber and high strength resin, the aperture should be uniform, the number of micro-holes per unit area should be more, with a reasonable and most appropriate thickness;
Advanced longitudinal joint bonding without leakage.
Reasonable choice of sealing form to ensure no leakage at the connection with the filter;
The outer reinforcement should make the filter material component close to the inner frame to enhance the impact resistance.
3. Production process and equipment
The production environment, production process and production equipment determine the basic conditions for producing high quality filter elements.
In the production of filter element, longitudinal seam lap and upper and lower cover bonding is a very important link.
4. Appearance quality
It refers to the appearance impression made by the filter element, mainly including:
Top and bottom cover processing finish and surface treatment is beautiful;
Whether the corrugated filter material is uniform, whether it is perpendicular to the upper and lower cover;
Whether the viscose of upper and lower cover, filter material and longitudinal seam of filter material is suitable, uniform, free of bubbles and beautiful;
In short, to judge the quality of the filter element, we should not only look at the appearance, but also detect the inner quality of the filter element, and the latter is more important.
