First, the instrument overview
JL-6000 wet and dry laser particle size analyzer is a new type of laser particle size analyzer. It combines dry test and wet test. It can test dry powder of magnetic materials and powders that are not suitable for water (wet method). The powder of the emulsion can also be tested. The instrument has high intelligence, fast test speed, simple and convenient operation, good repeatability, and is suitable for various industries.
The instrument is divided into a dry sample introduction system and a wet sample introduction system. The dry system includes a main unit, an auxiliary machine (including a dust extraction system, a dust storage waste tank, a compressed air purification tank), and a silent air compressor. The wet system includes ultrasonic dispersion, mechanical agitator, sample circulation, and the like. Test dry or wet, no need to change the device, you can quickly achieve function conversion with a click of the mouse.
Second, the scope of application:
Research institutes, medicine, ferrite powder, neodymium iron boron, hard magnetic powder, soft magnetic powder, cement, cobalt powder, electronic materials, pesticides, pigments, ceramics, cosmetics, coatings, food, calcium carbonate, talcum powder, kaolin, oxidation Particle size distribution test of dry powder and emulsion materials in various industries such as aluminum, rare earth, catalyst, foaming agent, refractory material and graphite.
Third, the following briefly describes the operation method of JL-6000 wet and dry laser particle size analyzer
1) Brief description of the operation method of dry laser particle size analyzer
1. Dry the sample to avoid agglomeration of the sample and result in incorrect detection results;
2. Switch the software test mode to dry method;
3. Open the vacuum cleaner and connect the suction nozzle to the dry powder test bench;
4. Use a special brush to clean the stage and the loading cylinder, and use the spoon to evenly place the sample in the measuring cylinder;
5. Select the test content and related parameters in the software option bar;
6. Click the test button to start the sample test. A measuring cylinder can be tested continuously for 3 times.
7. Save the test file, enter the sample name, and view the test results.
8. Turn off the vacuum cleaner, remove the cartridge and clean it.
2) Brief description of the operation method of the wet laser particle size analyzer
1. Open the software and select automatic cleaning (you can also choose semi-automatic cleaning);
2. Check whether the ultrasonic, circulating pump and agitator are working normally; the instrument is zeroed.
3, powder preparation, easy to disperse the powder can be directly added to the sample cell, if it is not easy to disperse the powder, first stir and disperse in the beaker
Or ultrasonic dispersion.
5. Click the test button to start the sample test.
6. Save the test file, enter the sample name, and view the test results.
7. After each test, select a fully automatic or semi-automatic cleaning circulation pipe to keep the test pipe clean.
Third, the instrument features:
1. The wet test set sample cell, ultrasonic disperser, agitator, circulation pump, and fully automatic cleaning are integrated, and the sample flows in the pipeline for a short time, avoiding delamination and re-agglomeration after the sample is dispersed.
2, dry test with special sampling device, high-speed turbulent dispersion system (patent) shear collision and other effects, so that the powder is fully dispersed and the transmission distance is extremely short, to avoid secondary agglomeration after powder dispersion. The amount of sample used is low, and the test is about 2g-10g/time, depending on the characteristics of the sample.
3. The working point compensation technology (90-year patent number) is adopted. The voltages of all the detectors after the first-stage current amplification are independently transferred from the D/A operating point, and then amplified by the second-stage voltage. To ensure that all channels of the detector remain at a fixed maximum magnification under any conditions. Therefore, the test repeatability and stability are guaranteed to reach the measurement level of similar instruments abroad.
4. The instrument adopts metal casing, has good electromagnetic shielding performance, strong seismic performance, especially adopts dustproof and moisture proof design, and is suitable for places with poor working environment.
5. The test results have a variety of different report form formats, including cumulative particle size distribution data and curves, interval particle size distribution data and histograms, typical particle size values ​​such as D3, D10, D25, D50, D75, D84, D90, D97 Data such as volume average particle diameter and area average particle diameter and specific surface area. You can modify or edit the report content as needed. The output can be directly printed, or converted to BMP images, PDF and text files, etc., in Chinese and English for users to choose.
