Embodiment 1

[0020] This embodiment includes the following steps:

[0021] (1) Atomize the finishing solution under high pressure, and then spray it out under the action of a high-voltage electric field of 30Kv;

[0022] (2) The atomized finishing liquid is coated on the surface of the filter material from high pressure to low pressure under the action of an electric field;

[0023] (3) Then, the filter material coated with the finishing solution is subjected to high temperature setting and solidification.

[0024] The finishing solution of this embodiment comprises the following components by weight: 8% PTFE emulsion, 2% ethanol, 7% high temperature resistant adhesive, 1% penetrant JFC, and the rest is deionized water. The high-temperature-resistant adhesive of this embodiment is commercially available ZS-1071 produced by Beijing Zhisheng Weihua Company.

[0025] like figure 1 As shown, the high-voltage atomization in this embodiment uses high-voltage atomization equipment, and the hig...

Embodiment 2

[0029] This embodiment includes the following steps:

[0030] (1) Atomize the finishing liquid under high pressure, and then spray it out under the action of a high voltage electric field of 18Kv;

[0031] (2) The atomized finishing liquid is coated on the surface of the filter material from high pressure to low pressure under the action of an electric field;

[0032] (3) Then, the filter material coated with the finishing solution is subjected to high temperature setting and solidification.

[0033] The finishing solution of this embodiment comprises the following components by weight: 6% of PTFE emulsion, 1% of ethanol, 5% of high temperature resistant adhesive, 1% of penetrant JFC, and the rest is deionized water.

[0034] Other implementations are the same as in Example 1.

Embodiment 3

[0036] This embodiment includes the following steps:

[0037] (1) Atomize the finishing solution under high pressure, and then spray it out under the action of a high-voltage electric field of 25Kv;

[0038] (2) The atomized finishing liquid is coated on the surface of the filter material from high pressure to low pressure under the action of an electric field;

[0039] (3) Then, the filter material coated with the finishing solution is subjected to high temperature setting and solidification.

[0040] The finishing solution of this embodiment comprises the following components by weight: 7% of PTFE emulsion, 1% of ethanol, 6% of high temperature resistant adhesive, 1% of penetrant JFC, and the rest is deionized water.

[0041] Other implementations are the same as in Example 1.

Abstract

The invention discloses a finishing method and application of a fine spraying filter material. The finishing solution is atomized at high pressure, and then sprayed out under the action of a high-voltage electric field of 18-30Kv; the atomized finishing solution changes from high pressure to low pressure under the action of an electric field The direction is coated on the surface of the filter material; then the filter material coated with finishing liquid is cured at high temperature. The application of a finishing method of finely sprayed filter material in non-woven filter material. The invention has a simple process, can reduce environmental pollution, save energy, improve the coating effect of the finishing liquid on the filter material, further achieve high-efficiency filtration, and simultaneously achieve the purpose of electret treatment.

Description

technical field [0001] The invention relates to a finishing method of a non-woven filter material, in particular to a finishing method and application of a finely sprayed filter material. Background technique [0002] Due to the rapid development of my country's industry, a large amount of exhaust gas and smoke are produced, which aggravates air pollution. The frequency of smog weather is getting higher and higher, and the scope is getting bigger and bigger, almost covering most of our country. [0003] The general conventional method to control smog is to use filter devices with filter materials, and filter materials with different materials and pore sizes can be selected according to needs. [0004] The use of non-woven filter materials has increased geometrically. In the stage of filter material finishing, the use of water resources and textile auxiliaries has also caused great damage to the environment. Contents of the invention [0005] The purpose of the present inv...
