1. Watch the color in sight
Observe the color of the garnet sand through the naked eye is light red or dark red. The color of light magnesium aluminum pitch is pink, while high -quality iron aluminum garnet with high hardness is rich in FE2O3 and Al2O3 ingredients because of higher content. RZG Almindine Garnet.
2. the hardness of the granules under the hand is tested by the hardness of the hand, which can observe the degree of weathering of the dumpling water knife sand to a certain extent. The high-cut water knife sand needs to be used for processing for raw materials. Mo’s hardness is 7.5-8, which is carefully crushed after 4 times, the edges and sharpness, and the damage rate is low to ensure efficient cutting speed.
3. observe the purity, identify the garnet sand of different manufacturers in the empty mineral water bottle (usually according to sand and water 1: 9 or 1: 5), shake for a few minutes. , About 3.9-4.1, the water knife sand will quickly settle down and place it on the table. Compared with the turbidity of the water above, it can be seen how much the floating impurities are. It is also called solid suspension. The substances that float on it slowly or do not settle down are impurities, which are invalid particles and cannot play a cut effect. The iron -aluminum garnet water sword sand, which is washed 6 times, has no dust and ineffective fine particles that affect the cutting efficiency, and will not hinder the free flow of the dripper water knife sand.
4. check the particle size distribution of garnet sand. According to the usual experience, customers can grab a handful of garnet sand and put them in their hands to basically see the distribution of particles. The high -quality garnet water knife sand uses a scientific granules with water knife sand, large particles play a cut effect, and the fine sand plays a grinding effect. The processed product cutting surface is smooth and vertical. Circular water is used for scientific cleaning 6 times, and 4 times sieved to ensure that the dust content is extremely low, and the waste sand is very easy to clean up. Guaranteed continuous and efficient cutting work
