What is walnut powder?
Walnut powder, also known as walnut sand, is produced by grinding crushed walnut shells into a fine powder after a rigorous selection process. It possesses remarkable anti-pressure and wear-resistant properties.
Walnut sand features a multitude of surface pores that grant it exceptional adsorption capabilities. It is non-toxic and corrosion-resistant, demonstrating resistance to dissolution in acids, alkalis, and water.
As a pure, natural polishing material, walnut sand boasts a hardness level that falls between that of metals and carbon deposits. This unique characteristic allows it to effectively and thoroughly clean the intake pipe and the back side of the intake valve without causing any damage.
