Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0023] Such as figure 1 As shown, the present invention provides a method for evaluating the stability of the filter value of a metal wire weaving dense mesh, comprising the steps of:

[0024] Step 1, the metal wire weaving dense mesh 2 is fixed between two sheet-like carriers 1 with smooth surfaces, and the sheet-like carriers 1 are air-tight materials, such as aluminum foil boards or wrapping boards, which can be considered as air-tight materials , Another example is a stainless steel plate, aluminum plate or copper plate with a thickness of 0.25mm. The thickness of these materials can make the stainless steel plate, aluminum plate or copper plate almost airtight, which can be considered as an airtight material. Each of the two sheet carriers 1 is provided with a through h...

Abstract

The invention discloses a method for evaluating stability of a metal wire woven dense net filter value. The method comprises the following steps that 1, a metal wire dense net is fixed between two sheet-shaped carriers with smooth surfaces, through holes are formed in the two sheet-shaped carriers respectively, the through holes are in mirror symmetry about the metal wire woven dense net, and the metal wire woven dense net is exposed out of the sheet-shaped carriers; 2, an air permeability tester is used for testing or calculating the air permeability of the metal wire woven dense net exposed out of the through holes, the stability of the filter value of the metal wire woven dense net is evaluated according to the air permeability, and the distance between any two points on the through holes is not larger than 35 mm. According to the method, the metal wire woven dense net is fixed to the sheet-shaped carriers, the air permeability of the metal wire woven dense net can be tested through the air permeability tester, and therefore the stability of the filter value of the metal wire woven dense net can be evaluated according to the air permeability of the metal wire woven dense net.

Description

technical field [0001] The invention relates to a method for evaluating the stability of the filtration value of a metal wire woven dense net. Background technique [0002] Dense mesh includes forward dense mesh and reverse dense mesh. It is braided with high-quality stainless steel wire. The warp and weft wire diameters of the dense mesh are different, the number of meshes is different, the thickness of the mesh, the filtration accuracy and the service life are significantly improved compared with the square hole mesh. So far in China, there is no effective detection tool that can measure the filtration value of metal wire woven dense mesh. In the production process, in many cases, it is necessary to judge whether the filtration value of the product is stable and whether it meets the needs of customers. At present, there is no effective method that can play the above role. [0003] The air permeability tester can be used to test the air permeability of leather, textiles,...
