in the second step, the cleaning time of the ultrasonic cleaner 01 is 900 seconds;
the total number of grinding times of the grinding tool to be cleaned after the last cleaning is 152 times.
In this comparative example, a small amount of coagulated cutting chips were adhered to the surface of the polishing tool 1 after cleaning, and the glossiness was general.
Experimental example
The end faces of the polarizers which had the problem of withdrawal of the above-mentioned example 1-6 and comparative example 1-3 were polished by the polishing tool 1, and the polished polarizers were subjected to performance testing according to GB/T25275-2010 test methods for optical properties and weather resistance of polarizers for Liquid Crystal Displays (LCDs), and the test results are shown in Table 1.
TABLE 1 data on performance of polarizers ground by the cutters of examples 1-6 and comparative examples 1-3
The defective polarizer was polished with the polishing tool 1 cleaned in examples 1 to 6, and the end surface appearance was good.
The sample of example 4 after the polishing tool 1 polished the defective polarizer is shown in fig. 9.
As shown in Table 1, the polarizer polished by the polishing tool 1 in examples 1 to 6 had a degree of polarization P, transmittance T and color tone satisfying the use requirements.
As can be seen from table 1, the degree of polarization P and the transmittance T of the polarizer polished by the polishing tool 1 after cleaning in comparative example 1 cannot meet the use requirement, the degree of polarization P, the transmittance T and the color tone H of the polarizer polished by the polishing tool 1 after cleaning in comparative example 2 cannot meet the use requirement, and the color tone H of the polarizer polished by the polishing tool 1 after cleaning in comparative example 3 cannot meet the use requirement.
In addition, in the polarizers polished by the polishing tools 1 of examples 1 to 6 and comparative example 3, the reason for the withdrawal of the polishing tool 1 was solved, the phenomenon of bubbles, white edges and peripheral floating did not occur in the polarizers, and in the polarizers polished by the polishing tools 1 of comparative example 1 and comparative example 2, the reason for the withdrawal of the polishing tool 1 was not solved, and the phenomenon of peripheral floating still occurred in the polarizers.
Therefore, by adopting the cleaning process, the grinding cutter 1 for grinding the defective polaroid can grind the polaroid which is recovered to the normal use standard after cleaning, the cleaning effect is more obvious after the cleaning agent is added, the longer the cleaning time is, the higher the temperature is in the use temperature range of the cleaning agent, and the better the cleaning effect is.
Example 7
The embodiment discloses a polishing method of a polarizer polishing tool, referring to fig. 10, the method includes the following steps:
step one: selecting a grinding tool 1;
step two: grinding the laminated polaroids for preset times by adopting the grinding cutter 1 in the first step, wherein the preset grinding times are set to be 40-60 times, and in the embodiment, 50 times;
step three: the grinding times of the grinding cutter 1 in the second step reach preset times, and the grinding cutter is cleaned by adopting the cleaning process of the polaroid grinding cutter;
step four: and (3) grinding the laminated polaroids for preset times by adopting the grinding cutter 1 cleaned in the step (III), wherein the preset grinding times are set to be 40-60 times, and in the embodiment, 50 times.
