Introduction of walnut shell
walnut shell adopts the high quality of pecan shell as raw material, after crushing, polishing, steaming, washing, drug treatment, two filter processing. Walnut shell granular yellowish-brown, toughness, wear resistance compressive strength, strong adsorption capacity, oil immersion, agglomerate, not rot, stable chemical properties, does not contain toxic substances.
Walnut shell abrasive for glasses accessories, pearl jewelry, buttons, electronic parts, stamping parts and other industries of polishing deburring, excellent wear resistance, uniform particle size, high content of shell. 
 

Walnut shell features
1, compressive ability: walnut shell grain particle size 1.25 1.60 mm, the average compressive strength limit of 0.2295 KN (23.40 KGF). Walnut shell grain particle size 0.80 1.00 mm, the average compressive strength limit of 0.165 KN (16.84 KGF).
2, walnut shell has big strength, compressive strength, oil resistance, wear-resisting not agglomerate, decay characteristics. Use it to do abrasive, won't destroy the workpiece surface polishing effect is good.
3, stable chemical properties: walnut shell chemical stability is good, does 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 filter material due to the hardness of itself, the proportion of ideal, porous and multifaceted, and the special physical and chemical treatment, the pigment, fat, oil, electric ion removal clean), make it has strong oil removal in water treatment performance, in addition to the solid particles.

 

Walnut shell abrasive applications
Walnut shell abrasive used for mould, instrument, electrical, plastic, gold and silver jewelry, metal, glass, glasses, watches, golf clubs, hairpins and buttons such as cleaning and polishing. Mainly used for blast cleaning industry, such as paint, rust, chemical materials, such as existence of workpiece surface, has the effect of removing survivor and smooth surface.
Walnut shell filter material widely used in oil field, chemical industry, leather and other industrial wastewater treatment and urban water supply and drainage engineering, is the most ideal water purification filter material of various filters.
Walnut shell pore forming material, used for ceramic bond, stomatal wheel into porous materials with uniform porosity, no smell, no pollution, easy to use, cheap, without damage to the body on the use of employees, safety, and the grinding wheel blowhole size can be arbitrary choice. Walnut shell can also be used as detergent auxiliary materials, etc.
