What is Walnut shell?
Walnut shell are crushed, ground and classified to standard mesh sizes that range from coarse grits to fine powders. It has excellent strength with natural and enduring specialty. It is use for well industry every different physical condition. They can also use again during the process.
It has wide usages in construction, furniture, adhesives, paint, plywood, resin, rubber, paint and cosmetic industries. Walnut shells flour can also use an additive for rubber and plastic industry.it also compatible with other product like anionic, non-ionic and cationic surfactants.
Advantages of Walnut Shell
1. High hardness, wear resistance, and good pressure resistance.
2. Easy to dissolve in acid and alkali solution.
3. Strong adsorption and dirt-cutting ability. Its adsorption rate is 27-50%.
4. Good hydrophilic, resistant to oil immersed.
5. Easy to backwashing and regeneration. It can be directly used for backwashing before    filtering.
6. Low operation cost, and easy to manage
Walnut shell in drilling
Walnut shell is ground walnut shell, a lost circulation material that can be used in both oil-base and water-base systems. It is available in three sizes, fine, medium and coarse. It can be mixed in combination with other LCM.
As a lost circulation material they are especially adapted for plugging induced fractures. Walnut shells are also used to reduce torgue and drag of drill pipe and drill collars, especially in high angle holes. They are used as a sweep to scour the well bore and tools when sticking clay is a problem.
Walnut Shell in filtration
In oil industry it has very important for water filtration. This filter material has high water and oil resistance and easy to reverse. It is easy to regenerate also. When using this in oil industry you will get best result from oil removal rate between %5 and %10 and oil content is significantly reduced to below 5mg/l by >95%.
Walnut Shell in Cosmetic
Walnut shell usages is bases on soaps and all of the product for bath. This % 100 natural products ingredient is an excellent microbead replacement and has been used in cosmetic formulations for over 30 years. Cosmetic services include sterilization and custom packaging
Walnut Shell in Polishing
It is soft polishing media, used in polishing metals, hardware, alloys, mechanical parts, beans seeds. and so on, which cleans and removes matter from surfaces without damaging underlying material.
Packing and storage the product
Package Small bags,15-25kgs/bags packed in PP and PE BAG, or as the customer’s require
Walnut Shell must be stored in a cool, dry place. To prevent moisture penetration. packs which have opened should be sealed again as soon as possible.
In view of the environmental and health hazards involved in the use of solvents for cleaning surfaces, in particular, large exterior Surfaces. These shells have become common practice to use an abrasive blasting technique wherein abrasive particles are propelled by a high pressure fluid against the Solid Surface.
In order to dislodge previously applied coatings, scale, dirt, grease or other contaminants. Hard, durable surfaces, such as heavy steel plating can be cleaned or stripped by a hard abrasive such as sand.
Softer metals, such as aluminum or more delicate Surfaces Such as polymer composite layers may require the use of a Softer abrasive material during blasting Such as plastic pellets or Sodium bicarbonate.
