Problems solved by technology

For this reason, there are many technological and technical difficulties in the manufacture of domestic molecular sieve runners, especially the corrugated molding process is a technical bottleneck, which leads to the fact that almost all domestic molecular sieve runners are imported from foreign countries such as Japan, and more than 90% of the market is imported by foreign countries. The company is monopolized, and as a result, the production cost of domestic enterprises has increased greatly, and it is urgent to break the monopoly of this technology

Embodiment Construction

[0021] Such as figure 1 As shown, a composite paper for VOCs industrial waste gas adsorption includes a base carrier 1, the base carrier 1 is made of glass fiber, and the specification of the glass fiber used is 10-30 g / square meter.

[0022] The base carrier 1 is coated with a slurry composite coating 2 . The slurry coating 2 is an aqueous PU slurry, and the mass ratio of each component in the slurry is: calcium carbonate 2.5, molecular sieve 20, 50% solid-containing aqueous PU 2.5, water 75, wherein the molecular sieve and calcium carbonate particle size D50 1-10 μm, the pH value of the slurry is 5-6, the viscosity of the slurry is 800-1500 mPa.s, and the loading capacity of the finally obtained slurry coating 2 is 50-70 g / square meter.

[0023] The base carrier 1 and the slurry coating 2 constitute an inner layer of composite paper, and the inner layer of composite paper is covered with a fiber outer layer 3 made of natural fibers or synthetic fibers. The thickness of the...

Abstract

The invention discloses composite paper for absorbing volatile organic chemicals (VOCs) industrial waste gas, and a manufacturing method of the composite paper. The composite paper comprises a base layer carrier, the base layer carrier is coated with a slurry composite coating, and an inner layer of the composite paper is formed by the base layer carrier and the slurry composite coating; a fiber outer layer formed by natural fiber or synthetic fiber covers the outside of the inner layer of the composite paper; the base layer carrier is made from a glass fiber material; the slurry composite coating is molecular sieve-containing waterborne polyurethane (PU) slurry. By improving the structure and processing technology of the composite paper, corrugated one-time forming is met; the method can effectively solve the processing problems of the composite paper, and effectively reduces the production cost of enterprises while guaranteeing the processing quality of the composite paper.

Description

technical field [0001] The invention relates to a composite paper for adsorption of industrial waste gas, in particular to a composite paper for adsorption of VOCs industrial waste gas and a manufacturing method thereof. Background technique [0002] VOCs are a large number of low-concentration volatile organic compounds such as benzene, toluene, and xylene contained in industrial organic waste gas. The treatment of VOCs pollution is an important part of air pollution control. [0003] At this stage, the adsorption technology of VOCs industrial waste gas is relatively mature. The adsorption technology is mainly concentrated on activated carbon adsorption, but there is a risk of combustion and fire in the process of activated carbon adsorption. [0004] For this reason, the application of molecular sieve adsorption technology has gradually emerged in recent years. Molecular sieve adsorption technology mainly uses an adsorption composite paper, which is mainly composed of a s...
