Detailed description of the invention
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.
The method improving ceramic powder grade, comprises the steps:
A, the ceramic matrix of powdery and particle diameter are stacked less than or equal to the ingredient powder windrow of described ceramic matrix particle diameter 1/10th；
B, described ceramic matrix is sufficiently mixed with described ingredient powder, makes the granule of the granule outer wrapping ingredient powder of described ceramic matrix.
The kind of described ingredient powder is one or more.
Utilize the captivation existed between granule, make thinner ingredient powder parcel be attached to the granule outer layer of described ceramic matrix, make tone or the performance optimization of described ceramic matrix, by low-grade ceramic powder high-grade, the ingredient powder consumption used is few, and low cost, effect is obvious.It is possible to further use multiple described ingredient powder, the comprehensive grade improving described ceramic powder.
Before described step a, the method first described ingredient powder being used corona discharge, make described ingredient powder with electrostatic charge.
Make the granule of described ingredient powder with electrostatic, the efficiency that the granule of the granule and described ceramic matrix that improve ingredient powder includes, improve bond strength, prevent from coming off, and mutually exclusive between the described ingredient powder granule with like charges, make described ingredient powder granule be included in the extexine of described ceramic matrix granule more uniformly.
The method making powder particles static electrification is a lot, and the method effect that the corona that the present invention selects is put a little is the most obvious.Polarity according to discharge tip is different, and corona discharge is divided into positive corona and negative corona two kinds, because the discharge inception voltage of negative corona is lower than positive corona voltage, and electric intensity is big, so we preferentially select negative supply.
The grain diameter of described ceramic matrix is 20-100 mesh, and wherein particle diameter is that the amounts of particles of 40-60 mesh is no less than 60%；The particle diameter of described ingredient powder is less than or equal to 1000 mesh.
The granule of described ceramic matrix and the granule of described ingredient powder, in this particle size range, can combination just.
The consumption of ingredient powder is the 0.5%～10% of ceramic matrix gross mass, and preferably 3%～5% wrap up effective in this range, and ingredient powder residue is few, does not haves the harmful effect that material performance is caused by the ingredient powder not wrapped up in a large number.
