Problems solved by technology

In particular, when the adhesive is exposed to the acidic substances in the exhaust gas for a long time, it will be gradually dissolved, and the dissolved adhesive will diffuse to the unpainted adhesive to expand the surface area of ​​the adsorbent, which makes it possible to reduce the wind resistance of the exhaust gas. The adsorption performance of the formed honeycomb adsorption film body is greatly reduced

preparation example Construction

[0038] see figure 1 and figure 2 , the embodiment of the present invention also provides a method for preparing the above-mentioned high-performance adsorption membrane 5, comprising the following steps:

[0039] Utilize the method of spotting at intervals to fix adsorbent particles (not shown) with a particle size of 200-500 μm on the activated carbon fiber type non-woven fabric film through adhesive particles 4 to make two kinds of flat type 2 and corrugated type 1 Membrane products; wherein, the particle size of the binder is 1 / 4-1 / 3 of the particle size of the adsorbent particles;

[0040] The flat type 2 and corrugated type 1 membrane products are made into a semi-honeycomb membrane product 3, and then the semi-honeycomb membrane products are laminated to obtain the high-performance adsorption membrane 5.

[0041] In order to realize the purpose of the present invention, the inventors have repeatedly studied and found that the activated carbon fiber non-woven fabric me...

Embodiment 1

[0067] The adsorbent uses 350 μm zeolite particles, and the thermoplastic adhesive uses a two-component hardening adhesive made of 100 μm methacrylic resin and polyisocyanate. Liquid hardening adhesive / zeolite = 28.6%, to make a VOCs-containing exhaust gas adsorption film (that is, the high-performance adsorption film).

Abstract

The invention is suitable for the field of protective articles, and provides high-performance adsorption film used for removing VOC exhaust gas. The film includes activated carbon fiber-type nonwoven fabric membranes and adsorbent particles. The adsorbent particles are clamped between the activated carbon fiber-type nonwoven fabric membranes and are fixed to the activated carbon fiber-type nonwoven fabric membranes through adhesive particles. The particle size of the adsorbent particles is 200-500 [mu]m. The particle size of the adhesive is one fourth to one third of the particle size of the adsorbent particles. In the film, the activated carbon fiber-type nonwoven fabric membranes are adopted as substrate filtration membranes, and activated carbon fibers when compared with activated carbon have higher adsorption capacity and higher adsorption-desorption speeds and have acid-resistant and alkali-resistant properties.

Description

technical field [0001] The invention belongs to the field of protective equipment, and in particular relates to a high-function adsorption film for removing VOCs waste gas. Background technique [0002] In recent years, many symptoms of nervous system allergies, such as bad housing syndrome caused by inhalation of VOCs (volatile organic compounds, volatile organic compounds), have been increasing. This is mainly caused by various paints, solvents, resins, adhesives, thinners, etc. Distribute a large amount of VOCs and cause environmental pollution, especially in an environment with high air tightness for energy saving (such as painting booths, high-end furniture residences, etc.), this impact is more serious. [0003] In order to solve the above problems, those skilled in the art have developed many waste gas adsorption membranes with adsorption function, such as chemical binding membranes, physical adsorption mechanism membranes, and catalyst decomposition mechanism membran...
