Main products and uses
Walnut shell filter material
Production method: After the walnut shell is fully dried, it is mechanically crushed and sifted to the mesh number 8/35#(particle size 0.5-2.8mm) of the particles, that is, the walnut shell filter material is obtained.
Main features: walnut shell filter material has high hardness, wear resistance, strong pressure resistance, does not contain toxic substances, chemical stability, good hydrophilicity, removal of oil and suspended matter ability, adsorption capacity is strong (adsorption rate of 27- 50%) and many other advantages.
Main application: walnut shell filter material is a kind of water purification filter material. It is widely used in oil wastewater treatment, chemical industry, metallurgy, thermoelectricity, printing and dyeing, paper making, wine making, leather and other oil industry circulating water treatment , domestic water and urban water supply and drainage engineering to remove oil and solid suspendeds. It is a new generation of filter material that replaces quartz sand filter material, improves water quality and greatly reduces water treatment costs.
Walnut shell abrasive
After the walnut shell is fully dried, it is mechanically crushed, polished, and sieved to small particles with mesh number 5-40#(particle size 0.4-4.0mm), that is, walnut shell abrasive is obtained.
Main features : walnut shell abrasive is a natural, environmentally friendly sandblasting, polishing, rolling material. Because of the walnut shell multi-edge and different size particles, has excellent wear resistance, uniform particle size, shell content is extremely high. And will not damage the surface of the workpiece, polishing effect is good.
Main uses : It is crystal products, eye accessories, bamboo products, hardware, bearings, precision instruments, jewelry, electronic components and other polishing, deburring, chamfering materials.
Walnut shell plugging particles
Production method : After the walnut shell is fully dried, it is mechanically pulverized, sifted and air-selected to form 10% coarse walnut shell powder with mesh size of 20-40 mesh, 55% medium walnut shell powder with particle size of 80- 200 mesh and 35% fine walnut shell powder with particle size of 300 mesh. After mixing evenly, other substances such as caustic soda and calcium carbonate powder are added for heating reaction. Finally dried into a powder walnut shell plugging agent.
Main features : According to the principle of particle grading, walnut shell powder is composed of coarse walnut shell powder, medium walnut shell powder and fine walnut shell powder with different particle sizes. Walnut shell powder, plant fiber, calcium carbonate powder and stabilizer are used together with each other, which has good sealing effect and strong resistance to high temperature and high pressure.
Main application: It is suitable for plugging of leakage and micro-fracture formation, permeable formation, shale formation, fractured zone formation and leakage layer which is difficult to determine the location of leakage in petroleum exploration and development.
Walnut shell cosmetic additive
The dried walnut shell is pulverized and grinded into 35-200#(particle size 0.5-0.075mm) walnut shell powder with a mesh number of 35-200#(particle size 0.5-0.075mm). After dusting, sorting, grinding, polishing , air sorting, screening, high temperature disinfection, ultraviolet sterilization, bagging and other processes, it can meet the safety, natural, health and other standards for cosmetic production. Additives to make cosmetics.
Main features : Walnut shell particles have a multi-faceted surface, hard shell but not harmful to human skin, so the addition of walnut shell scrubs, soaps, body washes, gels, creams, facial cleansers and other cosmetics can effectively remove skin dust, dirt, oil dirt, excess oil, aging cutin and Dead skin, so as to soften cutin, improve chicken skin, deep clean skin, delicate and smooth. Enhances metabolic activity.
Main Uses : Used in the production of scrubs, soaps, hand soap, hand soap, body wash, face cream additives.
Walnut shell pet bed material
Production method : The walnut shell is crushed and processed into walnut shell particles with 8-14 mesh sieve, 14-20 mesh sieve and 20-100 mesh sieve, mixed according to the ratio of 1:2:1, and then mixed with a certain proportion of sodium bentonite, wheat rice powder, citric acid, sodium bicarbonate, sodium carboxymethyl cellulose, etc. The granulation is carried out at 300℃ and the compression ratio is 1:6, and then the granulation particles are crushed with the roller crusher , and the caked cat litter can be produced after 3-20 mesh sieve.
Main features : good water absorption and bromine removal, easy to pet feces and urine clumping, easy to collect and handle.
Main uses : pet bed material for family pet to bury feces and urine and control odor. It can not only effectively solve the environmental pollution problem caused by pet waste, but also achieve the role of natural degradation. European and American countries are very optimistic about this product.
Walnut shell activated carbon
Production method : The walnut shell is dried, crushed to a particle size of less than 0.2mm, and then placed in the solution for activation, and then carbonized in the carbonization furnace under the condition of 600℃, after the end of carbonization, activated carbon can be obtained. The specific process is as follows: walnut shell → drying, crushing → solution impregnation → activation → carbonization → washing and filtration → drying → activated carbon.
Main features : large specific surface area, high strength, uniform particle size, strong adsorption performance and chemical stability, acid resistance, alkali resistance, high temperature resistance and so on.
Main applications : Widely used in medical and health, food processing, transportation, energy, agriculture, environmental protection, electronics, chemical industry, hydrometallurgy and military chemical protection and other fields.
