Detailed Product Description

The mechanical strength is high, the percentage of damage and the rate of wear sum of should not be bigger than 3% (percentage according to nature gauge). The chemical property is stable, does not contain the toxic substance. In the general acidity, the alkalinity, neutral Shui Zhongjun is insoluble. The leaving the plant product filters the material surveillance after the Chinese water treatment to examine the central determination: The hydrochloric acid may dissolving rate be 0.68% (proclaims standard is 3.5) may achieve the good purification effect in each kind of water source. The size grading is reasonable, is bigger than the surface area. The product outward appearance assumes spherically has the edges and corners, glossiness is good, after the mechanical vibrations three screening, the gradation conforms to the related technical specification. The uniformity coefficient (K60) is not bigger than 1.5 (the Japanese standard), the nonuniformity coefficient (K80) between 1.6-2.0, the percentage of voids is bigger than 50%. The particle size scope is smaller than assigns the lower limit particle size not to be bigger than 5% according to the weightometer, is bigger than assigns the upper limit particle size not to be bigger than 5% according to the weightometer
