Composite paper for industrial exhaust gas adsorption of VOCs and manufacturing method of composite paper

Abstract

The invention discloses composite paper for industrial exhaust gas adsorption of VOCs and a manufacturing method of the composite paper. The composite paper comprises a substrate carrier which is coated with a mixed slurry coating, mixed slurry of the mixed slurry coating permeates into the substrate carrier to enable the mixed slurry coating and the substrate carrier to constitute an integrated composite paper inner layer, and the composite paper inner layer is coated with a molecular sieve coating; the substrate carrier is made of fiberglass; the mixed slurry coating is made of the mixed slurry containing polyvinyl alcohol (PVA) and silica sol; and the molecular sieve coating is made of molecular sieve slurry containing an adhesive. By improving a composite paper structure and a processing process, the hardness and strength of the substrate carrier are effectively increased so as to meet the strength needs of corrugated forming and the strength needs after forming, meanwhile, the adhesion strength of the substrate carrier and an adsorption coating is improved exponentially, the processing problem of the composite paper is effectively solved, and the production cost of enterprisescan be effectively lowered while the processing quality of the composite paper is guaranteed.

Description

technical field [0001] The invention relates to an industrial waste gas adsorption composite paper, in particular to a composite paper used for VOCs industrial waste gas adsorption and a manufacturing method thereof. Background technique [0002] VOCs are a large amount of volatile organic compounds such as benzene, toluene, and xylene contained in industrial organic waste gas at low concentrations. When the concentration of VOCs is too high, it is easy to cause acute poisoning. In mild cases, headache, dizziness, cough, nausea, vomiting, or Intoxicated; in severe cases, liver poisoning and even coma will occur soon, and some may be life-threatening. Therefore, based on the serious harm of VOCs pollution, the control 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...

AI Technical Summary

Problems solved by technology

Molecular sieve adsorption technology mainly uses an adsorption composite paper, which is mainly composed of a substrate carrier and an adsorption coating on it, but the hardness and strength of the existing composite paper substrate carrier are relatively poor, and there is a large Difficult, not only is not conducive to the later tile forming, but also the corrugated strength after forming is not high

[0005] In addition, the adhesion strength between the substrate carrier of the existing composite paper and the adsorption coating on it is not high. If the adsorption paper is directly formed and processed, it is easy to cause the adhesion of the adsorption coating to the corrugating roll of the corrugating forming equipment, resulting in the substrate Separation of material carrier and adsorbent coating

[0006] Based on the above situation, 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 has led to almost all domestic molecular sieve runners being imported from foreign countries such as Japan, and more than 90% of the market has been used. The monopoly of foreign companies has resulted in a significant increase in production costs for domestic companies, and it is urgent to break the monopoly of this technology
