Walnut shell introduction
Walnut shell is a kind of degreasing, crushing, screening and other processing processed particle, surface pore, the adsorption effect fabric better polishing abrasive.
(a) particle size 1.25 1.60 mm of the walnut shell grain, the average compressive strength limit of 0.2295 KN (23.40 KGF).
(2) of the walnut shell grain particle size 0.80 1.00 mm, the average compressive strength limit of 0.165 KN (16.84 KGF).
(3) the chemical properties of stability, do not contain toxic substances, dissolved in acid, alkali, water volume is small, the loss of walnut shell in hydrochloric acid solution was 4.99%, the attrition rate of 3.8% in sodium hydroxide solution, does not cause deterioration of water quality.
Walnut shell use
Walnut shellfilter products widely used in oil, chemical industry, leather industry wastewater treatment and city water supply and drainage engineering, water is an ideal filter purification filter material
The main application of glasses accessories, polishing and polishing materials walnut shell pearl jewelry, buttons, electronic parts, stamping parts, etc. industries deburring,with excellent wear resistance, uniform particle size, high concentration of shell. Walnut shell is a natural roll materials, damage the workpiece surface abrasive with it not, good polishing effect.
Ceramic bond stomatal wheel pore forming material has uniform porosity, no smell, no pollution, easy to use, cheap, body condition, also on the use of employees safety.Moreover, the grinding wheel blowhole size can choose.
