Description
Technical field
The present invention relates to technical field of waste gas treatment, more particularly to a kind of preparation method of organic gas absorption purifier.
Background technology
In the world, since revolution is industrialized, with the fast development of petrochemical industry, and consumption combustion
The development of the auto industry of oil, result in increasingly sharpening for environmental pollution, a large amount of discharges of motor vehicle exhaust, to going out for people
Row, atmospheric environment etc. cause serious negative effect, while such as emulsion paint, wallpaper, ground, heat-insulating material, viscous in household room
Agent is tied, the outdoor organic solvent as used in coating factory, semiconductor factory or printery will also result in air ring through volatilization
The pollution in border.
For component, organic gas mainly includes the materials such as formaldehyde, ammonia, ethylene glycol, esters.If it is directly entered air
In, also it can form more harmful organic filler with reactions such as sunlight or ozone.When organic gas reaches a certain concentration in air
When, the symptom such as headache, Nausea and vomiting, weak can be caused, even trigger twitch, stupor, injury liver, kidney, brain when serious
And nervous system, cause the serious consequences such as failure of memory.As the improvement of people's living standards, people put forward its living environment
Increasingly higher demands are gone out, which includes air ambient problem.
Porous carbon fiber is a kind of new porous fibrous sorbing material, is had because of its unique pore structure and form
There are the specific surface area of more general porous charcoal bigger, the pore volume of higher, the faster rate of adsorption and stronger power of regeneration.Since upper
Since century the seventies appearance, air purification, exhaust gas wastewater treatment, military protection, metal recovery, electricity just it have been widely used in
Sub- equipment etc..At present, the porous carbon fiber of in the market mainly has polyacrylonitrile-radical porous carbon fiber, asphaltic base porous carbon fibre
Dimension, viscose glue base porous carbon fiber and phenolic aldehyde base porous carbon fiber etc., different carbon fibers carbonization speed, production carbon rate, porosity with
And the toughness after carbonization is different.Therefore, it is necessary to combine traditional carbon fibres preparation method, pass through Optimal improvements technique, there is provided
Aperture is small, porosity is high, fiber homogeneity is good and combines the strong porous carbon fiber of power.
At the same time, since the preparation process of carbon fiber includes carbonization or graphitization so that the carbon atom of carbon fiber surface
Stack orientation is more consistent, atom interlamellar spacing smaller, so fiber surface shows as nonpolar and chemical inertness, other carbon fiber surface
There are the shortcomings such as hydrophobic, smooth, absorption property is low in face, and the storeroom interface adhesion for causing carbon fiber compound with it is poor.Therefore, need
Carbon fiber surface is modified, improve its interface binding intensity with composite material.
