Description
Technical field
The present invention relates to the preparation of superfine powder, relate in particular to a kind of preparation method of ultra-fine amorphous graphite powder and matching used process equipment with it.
Background technology
Graphite material is reaching after 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 conduct, to characteristics such as electromagnetic abnormal absorptions.Therefore,, at scientific research and industrial circle, the preparation of ultrafine powder has special meaning.Industrial widely used amorphous graphite powder footpath D at present
90in 45um left and right, in special industry, graphite particle diameter D
90about 15um, for example graphite cathode material.
Abroad just Comminution Technology for Ultrafine Powders is studied since the forties in 20th century, particularly superfine technique and the equipment of the country such as the U.S., Germany, Japan, Britain have reached higher level, and its superfine powder product granularity can be controlled in any grade of 0.5 ~ 10mm.At home, just start superfine technique and equipment to possess some special knowledge the sixties in 20th century, but due to science and technology and attention degree inadequate, slower development always, until the eighties, along with the rise of new high-tech industry is just able to fast development.At present, can produce and in type machine performance compares favourably in the world all kinds flour mill.Wherein mainly contain airflow milling, vibromill, 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 in the Use and preparation method difference of every profession and trade, at present to the ununified saying of superfine powder granularity boundary, general several nanometers to the powder of tens of microns can be called superfine powder.For nonmetallic mineral processing, what Chinese scholar was relatively approved is defined as: 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 is to utilize acid with strong oxidizing property as concentrated sulfuric acid red fuming nitric acid (RFNA) etc. destroys the intermolecular chemical bond of graphite as strong oxidizer, forms graphite oxide, then graphite oxide is processed, and obtains ultra micro graphite composite powder.Physical partition method refers to that graphite is layer structure, if the Van der Waals force combination that molecule passes through between layers, with other hard materials or self high velocity impact in the situation that, layer can be peeled off with layer in generation.
Main research of super-pine crush equipment mainly contains and stirs mill, vibromill and airflow milling at present.Stir that the highest, the pulverized particles of mill capacity usage ratio is thin, epigranular, but yield poorly; The advantages such as vibromill has efficiently, the scope of application is wide, product granularity is thin, its product granularity D
50can reach below 1mm, but also there is the shortcomings such as volume is little, the easy damage of equipment; 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 large, product fineness is thin, narrow particle size distribution, the contaminated degree of product are low, but simultaneously auxiliary facility require loaded down with trivial details, material size is required also relatively strict 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 constantly to seek to be applicable to the process equipment in self field.
