Embodiment 2

[0037] A method for testing the electrostatic decay of melt-blown cloth, using the processing device described in the above-mentioned embodiment 1 to test, comprising the following steps:

[0038] (1) Sample preparation: cut the sample to be tested so that the sample size can completely cover the sample processing area;

[0039] (2) Parameter setting: set the humidity and wind speed parameters of the processing device, wait for balance, and place the sample when the humidity display reaches the set value;

[0040] (3) Place the sample: Under the action of the servo motor, the sample placing platform slides out of the box along the guide rail, and the cut sample is placed on the sample placing platform, which is placed flat and without wrinkles, and the center of the sample is aligned with the center of the sample processing area. Then use the sample fixing fixture to fix the sample, and then start the servo motor to drive the sample placement table into the box after placing i...

Abstract

The invention belongs to the technical field of material testing, and particularly relates to a melt-blown cloth electrostatic attenuation treatment device and a test method. The device comprises a box body, an intelligent control unit, a humidifying unit, an air draft unit and a sample placing unit, wherein the humidifying unit is located at the bottom part of the box body and comprises a humidifier and a humidity sensor; the sample placing unit is located in the middle of the box body and comprises a sample placing table, a circular hollow sample processing area is arranged in the middle of the sample placing table, the lower surface of the sample placing table is connected with a sliding block, the sliding block is arranged on a guide rail, and the sliding block can slide front and back along the guide rail under the action of a servo motor; and the air draft unit comprises a fan located on the top part of the box body, and an air inlet of the fan communicates with an air outlet in the top part of the box body. The melt-blown cloth electrostatic attenuation treatment device can simulate the influence of moisture and wind blowing on static attenuation in actual use, so that the influence degree of moisture and wind blowing on static attenuation can be researched, and the quality and durability of melt-blown cloth can be judged.

Description

technical field [0001] The invention belongs to the technical field of material testing, and in particular relates to an electrostatic attenuation treatment device and a testing method for melt blown cloth. Background technique [0002] Melt-blown cloth is used as an air filter material, and the use environment is usually subject to moisture and wind. During use, there is a phenomenon of electrostatic attenuation. Under the action of moisture, the attenuation speed is faster. However, there is currently no instrument in the prior art that can simulate the influence of the actual application environment on static decay, which brings inconvenience to the static decay test of melt blown cloth. [0003] Therefore, it is necessary to research and develop a melt-blown cloth electrostatic attenuation treatment device in order to study the influence of moisture and wind on electrostatic attenuation, and also to judge the quality of melt-blown cloth. Contents of the invention [0...
