Description
1-2mm walnut shell / nut shell filters for water treatmentAppearance: Shiny, beautiful, brown. High-quality fruit (coconut, apricot) shell as raw materials, it is refined handled and screening made by water vapor activation crumbs.
Features: Developed gap, good adsorption properties, high strength, easy regeneration, economic and durable and so on.
Uses: It is used for oil field, refining, environmental protection, chemical industry wastewater treatment and so on.Walnut shell filter features1, compressive ability: walnut shell filter 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 filter applicationsWalnut 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.
