Abstract
The present invention relates to a kind of production method of titanium dioxide, in particular it relates to the grinding technics of polymolecularity titanium dioxide.Grinding steps are the increase roll-in mill apparatus under kiln, and thing is introduced into roll mill and is ground under kiln, and thing enters back into wet milk grinding under the kiln for grinding.The method that a kind of production method of polymolecularity titanium dioxide of the present invention is used, improves 20 ° of gloss of product, and the aqueous height for reducing product is stirred, and improves the dispersiveness of product.
Description
Technical field
The present invention relates to a kind of production method of titanium dioxide, in particular it relates to the life of polymolecularity titanium dioxide
Product method.
Background technology
Titanium dioxide is a kind of Chinese white, is widely used in coating, chemical fibre, rubber, enamel, ceramics, plastics, papermaking, print
The industry such as brush ink, electronic ceramics, glass, welding rod, cosmetics.Pigment is a kind of fine particle, particle diameter it is minimum less than 1 μ
M, is compared with particle inside due to the molecular number of these particle surfaces and occupies sizable ratio, the exposed molecule in particle surface
Among uneven in the field of force, there is energy very high in pigment particles surface, and itself plays pendulum, and this causes it
There are more performances than general solid, dispersion process of the pigment in color spreading agent is affected.
This ultra-fine state of pigment particles renders it susceptible to be distributed in its insoluble medium, and has and medium between
Certain active force and constitute a system, but due to a variety of properties of itself, it is difficult to stable dispersion, between particle
There is aggregation to be inclined to.The primary particle surface free energy of pigment is very high, has aggregation tendency to reduce surface area between particle, reduces certainly
By energy.Primary particle is bonded together to form offspring, more has some primary particles and offspring to jointly form again
Bigger aggregation, the diameter of this like-particles is just expanded a lot.So, pigment in coating application, in order to reach coating institute
The fineness for needing, it is necessary to smash these aggregations.Using roll mill, smaller particless fineness is reached, meet industrial application needs.
The content of the invention
The present invention is directed to the deficiencies in the prior art, and an object of the present invention is solution above-mentioned in the prior art
One or more problems for existing.
An object of the present invention is to provide a kind of production method of polymolecularity titanium dioxide.
To achieve these goals, the technical solution adopted by the present invention is：A kind of production method of polymolecularity titanium dioxide,
Increase roll-in mill apparatus under kiln, thing is introduced into roll mill and is ground under kiln, thing enters back into wet milk grinding under the kiln for grinding.
Preferably, the material that the roll-in mill apparatus are used is stainless steel.
Preferably, the roll-in mill apparatus roll mill pressure is 10-15MPa.
Preferably, the roll-in mill apparatus roll mill pressure is 13MPa.
Preferably, the Ginding process is specially：Powder is carried out to material after calcining using roll mill, wet-milling, serial sand
The poly- treatment of size degradation, reusing cyclone carries out classification treatment, and suitable material to the rear operation of preferable particle size is produced.
The method that a kind of production method of polymolecularity titanium dioxide of the present invention is used, improves 20 ° of gloss of product, drops
The aqueous height of low product is stirred, and improves the dispersiveness of product.
Specific embodiment
Above-mentioned example embodiment for a better understanding of the present invention, is carried out further with reference to specific example to it
Explanation.It should be appreciated that specific embodiment described herein is only used to explain the present invention, it is not intended to limit the present invention.
Embodiment 1
A kind of production method of polymolecularity titanium dioxide, increases roll-in mill apparatus under kiln, and thing is introduced into roll mill under kiln
It is ground, thing enters back into wet milk grinding under the kiln for grinding.Roll-in mill apparatus roll mill pressure is 13MPa.
Embodiment 2
A kind of production method of polymolecularity titanium dioxide, increases roll-in mill apparatus under kiln, and thing is introduced into roll mill under kiln
It is ground, thing enters back into wet milk grinding under the kiln for grinding, and then enters back into sand milling.Roll-in mill apparatus roll mill pressure is
13MPa。
Comparing embodiment 1
A kind of production method of polymolecularity titanium dioxide, thing grinds into wet milk under kiln.
The application method of table 1 obtains titanium dioxide and comparative example method obtains the performance test data of titanium dioxide
By above table it can be seen that, the product that the method for the present invention is obtained has great in 20 ° of gloss this parameters
Breakthrough, improve 22.1% than original glossiness, greatly improved the quality of titanium dioxide.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
