Embodiment Construction

[0023] (1) Cleaning method of test sieve

[0024] Clean the test sieve to be cleaned with a brush and gently rinse it in a clear water tank to remove the powder and impurities on the upper surface of the test sieve; add water to the cleaning tank of the ultrasonic cleaner until it is 2cm away from the surface of the cleaning tank; the test sieve Put them into the cleaning tank of the ultrasonic cleaning machine in order of mesh number from high to low for cleaning, and only one test sieve can be placed for cleaning at a time; after the test sieve is submerged in water, turn on the power of the ultrasonic cleaning machine, and ultrasonically clean the front of the test sieve After 3 minutes, ultrasonically clean the reverse side of the test sieve for another 2 minutes, and change the cleaning position of the test sieve by hand every 30 seconds. If there are bubbles in the screen during cleaning, move the test sieve by hand to let the bubbles escape; After cleaning in sequence, ...

Abstract

The invention relates to a cleaning and calibrating method of a test sieve. The cleaning and calibrating method comprises the steps of cleaning of the test sieve and calibration of data. The cleaning and calibrating method is particularly as follows: the phenomena of aperture blockage, loosening and the like can occur after the net of the test sieve is used for a period of time, so that the test sieve needs to be cleaned, dried and then calibrated and corrected so as to be used for the test of granularity, and further the stability and the accuracy of the test of the granularity of the test sieve are ensured.

Description

technical field [0001] The invention relates to a method for cleaning and calibrating a test sieve, which belongs to the field of particle size testing of powder materials. Background technique [0002] The test sieve is widely used in the screening and testing of powder materials due to its convenient use and low cost. The test sieve is composed of many small stainless steel wires arranged in an orderly manner. Their mesh size is very small (micron level). When the test sieve is used for a certain number of times, the sieve hole will be blocked, the sieve wire will be loose, Breakage and other phenomena lead to inaccurate detection values ​​and large fluctuations. It is necessary to regularly clean and calibrate or even replace the test sieve. After cleaning and replacement, the test sieve must be recalibrated before it can be used to test the particle size. [0003] There are currently many methods for particle size detection, even for the same powder particle, different ...
