Preparation method of filtering adsorption paper

Abstract

The invention relates to a preparation method of filtering adsorption paper. The preparation method comprises the steps: taking powdered activated carbon with the amount of 50 kg each part, adding 50 kg of water in a raw material pool, and stirring evenly; putting 50 kg of a paper pulp fiber with purified water into a high-concentration hydrapulper, and uniformly pulping for 20 minutes; placing 300 kg of water, 25 kg of the paper pulp fiber and 50 kg of a synthetic fiber in a thermostat, stirring, after continuously stirring for 10 minutes, importing together with 50 kg of the thoroughly-soaked activated carbon into a high-concentration pulping pool, and adding 12.5 kg of a food-grade adhesive into the pulping pool; and allowing to go into a steam oven having four independently-operating parts. The preparation method has the beneficial effects that the filtering adsorption paper has double adsorption capabilities of activated carbon and activated alumina, the average pore size of the filtering adsorption paper can be stably controlled, and the gas permeability performance of the adsorption paper is allowed to be stable; the filtering paper thickness is uniform, the stiffness and the bursting strength are high, and the tensile strength is increased; a medium of the adsorption paper does not fall off in a mechanical machining process and a use process; and the product can be arbitrarily folded, wound and slitted for use, and can be widely applied in filtration and adsorption of a gas phase and a liquid phase.

Description

technical field [0001] The invention relates to filtration and separation technology, in particular to a method for making filter adsorption paper. Background technique [0002] Filter absorbent paper has many uses and can often be used to adsorb gas or liquid. For example, the filter paper usually made of filter media materials such as glass wool or fiber paper has low strength and is easy to break, which often leads to falling off and causing its own pollution, so the structure is unstable; for another example, imitation sheepskin or Filter paper made of metal mesh is easy to clog. After the above comparison, it can be seen that the disadvantages of the current ordinary filter adsorption paper are: ①The average pore size distribution is uneven, and the air permeability index is poor; ②The stiffness and bursting resistance are small; ③The tensile strength is small; ④It cannot be folded and used; Inhomogeneous; ⑥ does not have the high-efficiency adsorption formaldehyde pe...
