Description
Technical field
The present invention relates to a kind of method that particle size analyzer tests plastics special titanium pigment granularity, particularly one kind is related to metallurgicalization
The method that the particle size analyzer in work field tests plastics special titanium pigment granularity.
Background technology
The pigment performance influence factor of titanium dioxide is more, wherein particle size and distribution be critically important influence factor it
One.The granule size of titanium white powder particles, has a strong impact on its scattering coefficient.When its particle diameter is 200nm, scattering coefficient highest, this
When pigment reducing power and hiding rare it is optimal, preferably, but particle diameter becomes hour, weatherability just corresponding decline for whiteness and glossiness.Face
Expect the titanium dioxide of function admirable, the breadth of particle size distribution of its particle should be narrow as far as possible.Therefore the granularity of titanium dioxide is accurately detected
Distribution, the quality of intermediate products and final product quality can be tentatively judged from distribution map, is conducive to instructing Producing Titanium Dioxide.But it is existing
There is the scattered hardly possible of titanium dioxide in the method for testing of technology, measured result and legitimate reading difference is larger, it is impossible in true reflection
Between product and final product quality quality, be unfavorable for instructing the production and processing of titanium dioxide.
The content of the invention
Good sample medium system, the special titanium white production of Accurate Determining plastics can be obtained the invention provides a kind of
The method that the particle size analyzer of the average grain diameter of product tests plastics special titanium pigment granularity.
The present invention is the method for the particle size analyzer test plastics special titanium pigment granularity for solving the above problems used,
A, will titanium dioxide add solvent in be configured to titanium dioxide solution；
B, into titanium dioxide solution add dispersant；
C, decentralized processing；
D, sampling detection, determine its granularity；
The concentration of titanium dioxide is controlled, the amount that titanium dioxide is added in step A is 0.1-0.5g, and the amount of solvent is 50mL.
It is further that the solvent in step A is water, acetone, the one or more of ethanol.
It is further that dispersant described in step B is ammoniacal liquor, glycerine, the one or more of Macrogol 6000.
It is further that the addition of dispersant is controlled in 0.3%-0.5%.
It is further, it is scattered using ultrasonic wave added in step C.
It is further to carry out 2 ultrasonic wave addeds to disperse, the aid dispersion time is 15 minutes.
It is solvent from acetone and ethanol, solvent volume is 50mL, and the mass percent of wherein acetone is to be further
60%；It is dispersant from glycerine and Macrogol 6000, dosage is 0.3%；Solution disperses 30min under ultrasound,
15min/ times, twice.
The beneficial effects of the invention are as follows：Pass through the selection to solvent, the tune of decentralized processing technique using the present processes
It is whole, good dispersive property is obtained, the solution beneficial to test is obtained so that true particle diameter of the result of test close to product.
Embodiment
The method that the particle size analyzer that the application is used tests plastics special titanium pigment granularity,
A, will titanium dioxide add solvent in be configured to titanium dioxide solution；
B, into titanium dioxide solution add dispersant；
C, decentralized processing；
D, sampling detection, determine its granularity；
The concentration of titanium dioxide is controlled, the amount that titanium dioxide is added in step A is 0.1-0.5g, and the amount of solvent is 50mL.Adopt
With the amount of the solvent in aforementioned range and the amount of addition titanium dioxide the concentration of titanium dioxide can be made to be maintained at suitable scope, to increase
The degree of scatter of titanium dioxide, so as to improve the accuracy of granularity Detection.
Solvent in step A is water, acetone, the one or more of ethanol.Titanium dioxide can be helped using aforementioned solvents
Preferably disperse in the solution, so as to improve the degree of accuracy of granularity Detection.
Dispersant described in step B is ammoniacal liquor, glycerine, the one or more of Macrogol 6000.Using foregoing scattered
Agent can improve the degree of scatter of titanium dioxide in the solution, so as to improve the degree of accuracy of granularity Detection.
The addition of dispersant is controlled in 0.3%-0.5%.The amount of dispersant is controlled to enter one in 0.3%-0.5%
Step promotes titanium dioxide to disperse in a solvent.
It is scattered using ultrasonic wave added in step C.In order to increase degree of scatter, using the method for ultrasonic wave added, using super
Acoustic energy it is propagated, the various pieces of titanium dioxide solution is all sufficiently disperseed, to improve the accuracy finally detected.
Carry out 2 ultrasonic wave addeds to disperse, the aid dispersion time is 15 minutes.In order that scattered more abundant, the application is adopted
With the method for ultrasonic wave added twice.
