preparation example Construction

[0048] The present invention also provides a kind of preparation method of activated carbon fiber composite material, comprises the following steps:

[0049] After weighing activated carbon fiber chopped strands and / or activated carbon fiber powder, powdered activated carbon, short fibers, modified cellulose and auxiliary agents to obtain a mixed raw material, the mixed raw material is mixed with water evenly, and is prepared on a paper machine at one time. The net is shaped to form an activated carbon fiber composite material.

[0050] The present invention first weighs the activated carbon fiber chopped strands and / or activated carbon fiber powder, powdered activated carbon, short fiber, modified cellulose and auxiliary agents to obtain the mixed raw material, and then mixes the mixed raw material with water to obtain the mixed slurry material. Wherein, the mass ratio of the mixed raw material to water is preferably 1: (10-20), and in some specific embodiments of the presen...

Abstract

The invention is made of activated carbon fiber, short fiber, powdered activated carbon, modified cellulose and processing aids, etc. to make activated carbon fiber composite material, as the adsorption material of high-efficiency activated carbon filter element, overcomes the disadvantages of poor strength of activated carbon fiber felt and easy shedding The problem is that the rich and uniform microporous structure of activated carbon fibers is retained, and there are a large number of mesopores (ie, mesopores) of high-quality powdered and granular activated carbons, so the adsorption capacity is large, and the range of applicable organic matter is wide, and the material is prepared. The filter element is resistant to high temperature, acid and alkali, and can be widely used in the electroplating production line of the PCB industry.

Description

technical field [0001] The invention belongs to the technical field of activated carbon filter elements, and in particular relates to an activated carbon fiber composite material, a preparation method thereof and an activated carbon fiber composite filter element. Background technique [0002] In the electroplating industry, in order to make the coating bright and dense, additives are generally added. Among them, the most important brightener, as an organic substance, inevitably has phenomena such as decomposition. After its decomposition, in addition to the decrease in the brightness of the coating, it may also cause disadvantages such as loose coating. In the past, regular carbon treatment was usually carried out on the plating solution, but carbon treatment will bring certain problems, such as loss of plating solution, difficulty in sedimentation of carbon powder, and subsequent filtration, etc., which increases the difficulty of operation and labor costs. [0003] The u...
