To identify the filter cloth, we must first understand the several main technical indicators of the filter cloth. The main ones are density, thickness, weight, permeability, breaking strength and so on. More practical are density, thickness and weight, air permeability.

1. Look first. (Filter cloth color) In terms of large chemical fiber filter cloth white, good luster. Small chemical fiber filter cloth is dark, gray, and some filter felt such as Nomex, the color is yellow. (gloss of filter cloth) long fiber filter cloth, smooth surface, good shine, short fiber filter cloth surface with hair. (Filter cloth lines) And such as twill, plain, these lines can also help you judge the model. Because some specifications are different, the specifications will be different.

2. Touch again. (Softness) Of which the staple fiber such as 208,729 is soft like a plush cloth. 734, 747, 758, 3927 are all woven from the same raw material, but the thickness and density are different. 3927 is very rough, firm and not soft. Softness and roughness require you to touch the sample bit by bit and write it down. It is impossible to speak clearly. (Density) Density one is to touch by hand, the other is best to count, 10cm there are several threads. The corresponding filter cloth specifications have their own density coefficient, as long as the comparison can be roughly identified.

3. Reweigh. It is mainly to determine the thickness of the filter cloth, and it is best to take a small piece to weigh it (grams per square meter).

4. Reburn. Among them, polyester burns up black smoke, and polypropylene burns up blue light. I don't know if the others burned properly.

5, the above are a few technical opinions, from the idea of our order is to first determine whether it is woven cloth, and then determine the material (polyester, polypropylene or what), and then make a general judgment on long and short fiber, grain. Then according to the filter cloth thickness, density, gram weight technical index comprehensive determination filter cloth type. Of course, the premise is that you have a general specification sheet for the corresponding model.
