Abstract
The production process of porous carbon material includes the following procedures: selecting raw materials, breaking, sieving, proportioning materials and mixing them, adding adhesive and pore-forming agent, moulding and roasting, etc.. Said production process is simple, and easy to operate, and said invented product possesses uniformly-distributed orderly-arranged pores, has no scale, and has no pollution and toxic side effect, and possesses large strength, high-temp resistant and anti-corrosive properties.
Description
The present invention relates to a kind of production technique of filtering material.
More as filtering porous material as pottery, porcelain, synthetic graphite, electrical carbon etc., but the arrangement of these material mesopores is state of disarray at random, closed pore and apparent boring ratio example, pore size generally belong to no control state, thereby be difficult to adapt to smart filtering technology needs usually, once occurred carbon element polyporous materials in the past, but easily layering, peeled off with carbon fiber and organic polymer material.
The object of the present invention is to provide a kind of hole ordered arrangement, and production technique not stratified, adeciduate porous carbon material.
Technical solution of the present invention is:
A kind of production technique of porous carbon material, the difference of itself and prior art is: comprise the following steps: successively
1) chooses raw material: get refinery coke and/or pitch coke;
2) broken and screening: with disintegrating apparatus with raw material crushing, and by sieving into 3～6 kinds of grain-size grades, maximum particle diameter≤4mm;
3) batch mixes: will be through 2) 3～6 grade raw materials that obtain mix, and the weight percent of various grades is 5～60%;
4) add caking agent and pore-forming material: the pitch that adding is equivalent to above-mentioned dosage 20～40% is as caking agent, and adding is equivalent to the pore-forming material of above-mentioned dosage 20～50%;
5) moulding and roasting: use the ordinary process forming processes, carry out roasting in 220～460 hours then, the roasting top temperature is between 800～1250 ℃.
Disintegrating apparatus is equipment such as pair roller or Raymond mill.
Adopting coal-tar pitch or petroleum pitch is caking agent.
Pore-forming material adopts sodium-chlor or materials such as Repone K or modified phenolic resins.Moulding process is extrusion molding or compression molding, vibratory compaction.
Arrange in order in product provided by the present invention hole, and cell size can artificially be controlled, and generally 35～70%, the aperture is controlled in 10～250 μ scopes, and the distribution in hole is quite even.The possibility that there is not layering in product or comes off; Enough intensity being arranged, can be because of assembling fastening force effect not damage, the pressure effect does not damage in the time of can be because of back flushing yet; The high temperature of ability ≯ 550 ℃, ability is removed the corrosion of acid with strong oxidizing property and concentration ≯ 10% sodium hydroxide lye; Pollution-free to medium, have no side effect; Both can be used for the essence filter of the solution of coarse filtration, also can be used for the filtering and the catalyzer absorption carrier of impurity in the metallic solution.Production technique is simple, and is easy to operate.
