Introduction of fine aggregate methylene blue test equipment:
Advanced frequency modulation, numerical control and technology are adopted to improve the test accuracy and speed. It is a special instrument necessary for the laboratory. This method is suitable for determining whether expansive clay minerals exist in fine aggregates and determining their content to assess the cleanliness of aggregates. The supplier Hebei Dahong Experimental Instrument Co., Ltd. is expressed by methylene blue value MBV. This method is suitable for fine aggregates less than 2.36mm or less than 0.15mm, and can also be used for the quality inspection of mineral powder. When the pass rate of 0.075mm in fine aggregate is less than 3%, this test can be regarded as qualified.

Fine aggregate methylene blue test equipment operating method
1. Time setting: Turn on the power supply, first connect the "time setting" dip switch, set the mixing time.
2. The selection of "intelligent ordinary" key: it is necessary to use the ordinary test method when preparing methylene blue solution and doing the rapid evaluation test of methylene blue; In the methylene blue number (MBV) test, the intelligent test method supplier Hebei Dahong Experimental Instrument Co., Ltd. can be used, which greatly improves the accuracy and speed of the test.
3. Speed setting: When using intelligent speed test, the instrument has a default speed, which can be automatically switched. When using the ordinary speed test, the instrument is powered on and then press the 400/600 key, the speed is 600 RPM
