Description
Technical field
The present invention relates to a kind of abrading block, more particularly to a kind of composite grinding block is mainly used in polished bricks, quartz slate, big
The polishing on the surfaces such as reason stone plate.
Background technology
Ceramics, the surface grinding of stone material and polishing are a particularly important procedure in Ceramic manufacturing, its traditional grinding
Material is generally magnesia silicon carbide grinding block, this magnesia silicon carbide grinding block be applied to lithotome, artificial board, Ceramic Tiles,
The grinding and polishing of the material such as refractory material and concrete plate, but this magnesia silicon carbide grinding block high energy consumption, are used
Short life, only 1-2 hour, because consumption is too big, cause it is seriously polluted, and with environmental requirement more and more higher, sewage treatment
Expense more and more higher, causes the blowdown cost of transportation of magnesia silicon carbide grinding block to improve.In addition, resin-diamond abrading block uses the longevity
Life length, up to more than 80 times of traditional magnesia silicon carbide grinding block life-span, power consumption is low, and environmental pollution is small, it is considered to be replace
For the optimal selection of magnesia silicon carbide grinding block, still, on domestic market there is sharpness deficiency in resin grinding block, and polishing effect is not
Such as the problems such as magnesia silicon carbide grinding block, it is difficult to replace traditional magnesia silicon carbide grinding block always.Chinese patent literature number
