Grinding block for processing organic nanometer powder

Abstract

A set of grinding disks for preparing organic nanoparticles is composed of upper and lower grinding disks. Each of the grinding disks is composed of a casing, a core and a rubber pad. The upper core has a convex conic grinding surface and the lower core has a concave conic one. Said core consists of the core body divided into 8 sectoiral areas and the toothed ceramic bars inlaid in the grinding surface for generating shear force. Its advantages are high antiwear performance and not generating heat.

Description

technical field [0001] The invention relates to a grinding disc for processing organic nanometer powder. Background technique [0002] With the advancement of science and technology, making organic materials into ultra-fine powders has broad application prospects, and organic materials such as wool, silk, shells, etc., due to their own physical properties, the usual ceramic powder processing equipment (such as Ball mill, etc.) is difficult to process it into ultra-fine powder. Generally speaking, brittle materials are easier to be destroyed and processed into nano-scale powder, while organic materials generally have a crystalline structure, and the macromolecular molecular weight of the material is relatively large. Therefore, , this type of material has strong toughness, large elongation at break, and strong resistance to external damage. It is difficult to make this type of material reach the nanometer level when using a metal interface (metal grinding disc, etc.) Because...

[0002] With the advancement of science and technology, making organic materials into ultra-fine powders has broad application prospects, and organic materials such as wool, silk, shells, etc., due to their own physical properties, the usual ceramic powder processing equipment (such as Ball mill, etc.) is difficult to process it into ultra-fine powder. Generally speaking, brittle materials are easier to be destroyed and processed into nano-scale powder, while organic materials generally have a crystalline structure, and the macromolecular molecular weight of the material is relatively large. Therefore, , this type of material has strong toughness, large elongation at break, and strong resistance to external damage. It is difficult to make this type of material reach the nanometer level when using a metal interface (metal grinding disc, etc.) Because the wear resistance of metal materials is poor, and because the metal interface is easy to generate heat when it is rubbed, it will generally gradually change from white to yellow and finally black. Therefore, grinding discs made of metal materials or other types Advanced processing equipment often has disadvantages such as poor wear resistance and heat generation. So far, there is no ideal equipment for processing organic materials into nano-scale powders.
