Walnut shell is a natural rolling material. Using it as an abrasive will not damage the surface of the workpiece and has good polishing effect. It has stable chemical properties, does not contain toxic substances, and is soluble in acid, alkali and water. The amount is very small, the loss rate of walnut shells in hydrochloric acid solution is 4.99%, and the loss rate in sodium hydroxide solution is 3.8%, which will not cause the deterioration of water quality.

Industrial uses of walnut shells:

1. Exist as filter material (because of its microporous surface, large surface area, strong adsorption and interception ability, and strong adsorption capacity Filter materials)

Such as oil removal, water purification, etc., are often used in highly automatic control water injection filters, well filters, sewage filters, etc., and because of their high hardness and wear resistance Features such as this can reduce the operating costs of the machine and facilitate management.

2. Exists as a polishing material (because of its good durability and elasticity, and can be mixed with other abrasives, it is an ideal polishing and abrasive material)

Main applications: It can be used as an abrasive for polishing and deburring eyeglass accessories, pearl jewelry, buttons, electronic components, stamping parts, etc. without damaging the surface of the workpiece.

The functions of walnut shells in life:

1. It can be used as the bottom of flower pots. After crushing the walnut shells, spread them on the bottom of the flower pots, and use their water permeability and air permeability to Prevent plant root rot.

2. It can be used as a paint additive. After being crushed and mixed into the paint, it can not only increase the texture of the paint, but also greatly improve its performance.
