Description
Technical field
The present invention relates to the preparation of superfine powder, particularly relate to a kind of preparation method and matching used process equipment with it of ultra-fine amorphous graphite powder.
Background technology
Graphite material, after reaching certain particle size, due to " skin effect " and " bulk effect " of its particulate, can produce a series of peculiar character, as low in fusing point, chemism is high, magnetic is strong, heat transfer is good, to characteristics such as electromagnetic abnormal absorption.Therefore, at scientific research and industrial circle, the preparation of ultrafine powder has special meaning.Current industrial widely used amorphous graphite powder footpath D
90at about 45um, in special industry, graphite particle diameter D
90about 15um, such as graphite cathode material.
Abroad Comminution Technology for Ultrafine Powders is studied with regard to from the forties in 20th century, the superfine technique that particularly U.S., Germany, Japan, Britain etc. are national and equipment reach higher level, and its superfine powder product granularity can be controlled in any grade of 0.5 ~ 10mm.At home, just start the sixties in 20th century to possess some special knowledge to superfine technique and equipment, but due to science and technology and attention degree not, slower development always, until the eighties, along with the rise of new high-tech industry is just able to fast development.At present, all kinds flour mill compared favourably with in type machine performance in the world can have been produced.Wherein mainly contain, airflow milling, vibromill, Ball-stirring mill, impact grinding.Superfine powder is widely used in the new industry development such as fine ceramics, electronic technology, new material and biotechnology, particularly in nonmetallic ore processing, has great potentiality.
Because superfine powder is different at the Use and preparation method of every profession and trade, at present to the saying that superfine powder size limit is ununified, general a few nanometer can be called superfine powder to the powder of some tens of pm.For nonmetallic mineral processing, Chinese scholar compares being defined as of accreditation: the powder material that particle diameter is less than 10mm is called superfine powder.
Superfine graphite powder is standby mainly contains two kinds: one is fractionation, and another kind is physical partition method.Chemical reaction partition method utilizes acid with strong oxidizing property such as concentrated sulfuric acid red fuming nitric acid (RFNA) etc. to destroy chemical bond between graphitic molecules as strong oxidizer, forms graphite oxide, then process graphite oxide, obtain ultra micro graphite composite powder.Physical partition method refers to that graphite is layer structure, if the Van der Waals force that molecule passes through between layers combines, when with other hard materials or self high velocity impact, layer and layer can be peeling.
Research of super-pine crush equipment main at present mainly contains Ball-stirring mill, vibromill and airflow milling.But Ball-stirring mill capacity usage ratio is the highest, pulverized particles thin, epigranular yields poorly; The advantages such as vibromill has efficiently, the scope of application is wide, product granularity is thin, its product granularity D
50can below 1mm be reached, but also there is the shortcomings such as volume is little, equipment easily damages; Airflow milling is mainly used in the ultra-fine grinding of the following material of medium hardness, product fineness D
97can reach about 5 ~ 10mm, and production capacity is comparatively large, product fineness thin, the contaminated degree of narrow particle size distribution, product is low, but simultaneously auxiliary facility require loaded down with trivial details, require also relatively stricter to material size and energy consumption is high and cost is high.
In sum, the preparation of the superfine graphite powder of China has commercial significance, although existing a lot of disintegrating apparatus can meet the Production requirement in certain limit at present, due to disintegrating apparatus shortcoming separately, in special dimension processing, also need the process equipment constantly seeking self field applicable.
