Detailed Description
The technology of the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
Example 1:
the invention provides an improved titanium dioxide wear resistance detection method, which comprises the following steps:
s1, selecting a test object: testing by using sand materials in a post-treatment working section after calcination in the titanium pigment production process;
s2, pulping: adding desalted water into the sand grinding material in the step S1, and stirring the sand grinding material into slurry with the concentration of 445-450 g/L;
s3, adjusting viscosity: the viscosity of the slurry in S2 is regulated to 240-250 mPa.s by adding cellulose, so as to obtain a detection sample;
s4, testing: after the temperature of the detection sample is cooled to 25 ℃, 1L of the detection sample is taken and placed in a container with the volume of 2L, a weighed copper mesh is detachably fixed at the bottom of the container, a rotating shaft is arranged above the container, the rotating shaft is driven by a variable frequency motor, the lower end of the rotating shaft is detachably connected with a sleeve, the outer wall of the sleeve is sleeved with a rubber sleeve, the rubber sleeve is inserted into slurry in the container, new metal impurities brought into the slurry in the stirring process are avoided, the rubber sleeve is close to but not contacted with the copper mesh, the rotating shaft is enabled to rotate at 2400rpm through the variable frequency motor, the slurry is driven to rotate, the slurry and the copper mesh are enabled to rub, after the rotating shaft rotates for 5 ten thousand revolutions, the copper mesh is taken down, excessive attached titanium pigment is removed by pure water through ultrasonic, the balance is used for weighing after drying, and the difference between the two times of weighing data is the mass loss of the copper mesh and is recorded as a wear value;
s5, judging wear resistance: the abrasion value of the copper mesh sheet in the test result is less than or equal to 22mg, which is a first grade product; the wear value is between 22 and 32mg, and the product is qualified; abrasion values greater than 32mg are rejected.
After the test is finished, the detection sample in the container can be returned to the production system.
The working principle of the invention is that the inventor considers that the abrasion of the titanium dioxide comes from two aspects through a large amount of basic research, and the first is the particle morphology of the titanium dioxide, and the closer the particle is to the sphere, the lower the abrasion value is, and conversely, the closer to the irregular diamond, the higher the abrasion value is. Secondly, metal impurities in the titanium dioxide production process are also important reasons for influencing the abrasion value of the titanium dioxide, based on the two reasons, the inventor thinks that the finished titanium dioxide is not needed, and abrasion value evaluation and detection can be carried out only by using sand materials or wet grinding materials in the post-treatment working section of the calcined titanium dioxide, so that the cost can be saved, the quick reaction of a production workshop can be helped, and the product quality can be controlled. Because titanium dioxide particles are smaller than the micron level, the titanium dioxide particles can rub with the copper mesh sheet in a stirring state after pulping, the application only needs to adopt a common domestic copper mesh sheet, the mass loss is recorded as an abrasion value according to the mass loss of the copper mesh sheet before and after abrasion under a certain revolution condition, and the abrasion value is compared with the abrasion value of titanium dioxide which is detected to be qualified in advance, so that the abrasion resistance of a detection sample can be judged.
In this embodiment, because the concentration of the titanium dioxide is the condition that can most affect the abrasion value, the error of the measured abrasion value is larger when the concentration is too low, and the problems of agglomeration, net blocking and the like easily occur when the concentration is too high, and when the concentration slurry is 445-450 g/L through the discussion experiment, the error condition is the best no matter what the titanium dioxide is in net blocking condition, and the experimental result is shown in the following table 1:
TABLE 1 parallel sample test results when determining concentration
The inventor finds that in the concentration range, the abrasion value is lower when the viscosity is lower, the value of the final test result is smaller, and the influence of the same experimental error on the result is larger; and when the viscosity is larger and is more than 300 mPas, the material is easy to block the meshes of the copper mesh sheet, so that the experimental error is larger, and finally, through research experiments, the influence on the test result is smaller when the viscosity of the material is 240-250 mPas, and the viscosity experimental result is shown in the following table 2:
TABLE 2 results of abrasion value tests for the same concentration and different viscosities
Parallel replicates were performed after selecting good concentrations and viscosities, and it can be seen from the test results of table 3 that the reproducibility of the test results was good.
