Glass fiber framework molecular sieve paper with porous structure and preparation method of paper

Abstract

The invention discloses glass fiber framework molecular sieve paper with a porous structure. The paper is prepared from, by mass, 70-80% of molecular sieves, 5-15% of glass fibers and 5-15% of silicondioxide. The invention also discloses a preparation method of the glass fiber framework molecular sieve paper with the porous structure. In the prepared glass fiber framework molecular sieve paper with the porous structured, the content of the molecular sieves reaches 75% or above, the content of adsorption materials is high, and the adsorption capacity in unit volume is large. The porous structure in the paper can obviously increase the specific surface area of the glass fiber framework molecular sieve paper, increase the contact area between the paper and organic waste gas and the adsorption capacity, prolong the service life, reduce the pressure drop loss and adapt to different temperature and humidity environments.

Description

technical field [0001] The disclosure belongs to the field of environmental protection, and in particular relates to a glass fiber skeleton molecular sieve paper with a porous structure and a preparation method thereof. Background technique [0002] VOCs (Volatile Organic Compounds, VOCs) refer to organic compounds with a saturated vapor pressure greater than 133.32Pa at normal temperature and a boiling point between 50 and 260°C at normal pressure. Such substances have the characteristics of various types, complex components, and long-term low-dose release. They are a class of chemical substances that are carcinogenic, teratogenic, and mutagenic to the human body. They can participate in photochemical reactions and are also the main prerequisite for the formation of atmospheric particulate matter. Great damage to the atmospheric environment and human body. [0003] The main components of industrial organic waste gas are low-concentration volatile organic compounds such as ...

AI Technical Summary

Problems solved by technology

[0004] In view of the problems of low utilization rate and poor adsorption effect of adsorption materials in the prior art, the purpose of the present disclosure is to provide a glass fiber skeleton molecular sieve paper with a porous structure and a preparation method thereof. The molecular sieve paper has a high content of adsorption materials, The adsorption capacity per unit volume is large, and it can adapt to different temperature and humidity environments. It can be used as a fixed adsorption bed or the adsorption wheel core of the concentration wheel, and plays a positive role in the treatment of industrial organic waste gas.
