What are the characteristics of high-quality walnut shell abrasives

High-quality nut shell abrasives should be made from high-quality pecan shells, which are crushed, polished, steamed, washed, and treated with medicines, and processed through multiple screenings. Walnut shell abrasive is not only wear-resistant and compression-resistant, but also does not dissolve in acid-alkaline water, has strong dirt interception capacity and fast filtration speed. Walnut shell abrasives have undergone a special process (removal of pigments, fats, oils, and ions), so that the shell abrasives have strong degreasing performance in water treatment, solid particles removal, easy backwashing, etc. Performance, can be used in the treatment of oily sewage in oil fields.
       Walnut shell abrasives are a new generation of abrasives that replace quartz sand abrasives, improve water quality, and greatly reduce water treatment costs. Its compressive resistance is stronger. According to the data obtained from related tests, the average compressive limit of walnut shell particles with a particle size of 1.2-1.6mm is 0.2295KN (23.40kgf). Walnut shell particles with a particle size of 0.8-1.0mm have an average compressive limit of 0.165KN (16.84kgf). At the same time, the walnut shell abrasive has very stable chemical properties, does not contain toxic substances, and dissolves very little in acid, alkali, and water. The loss of walnut shell in hydrochloric acid solution is 4.99%, and the loss rate in sodium hydroxide solution is 3.8 %, will not cause deterioration of water quality.
