Description

technical field [0001] The invention relates to the technical field of application of nanometer materials, in particular to a kneading device using a nanometer coating. Background technique [0002] Nanomaterials refer to various materials made of tiny particles with diameters reaching the nanometer scale (1-100nm). Fundamental changes will occur, so that a series of physical properties will be more optimized, and even essential changes will occur, such as hardness, toughness, heat resistance, anti-corrosion performance and so on. [0003] Nanomaterials have special properties such as surface effects, small size effects, optical effects, quantum size effects, and macroscopic quantum size effects, which can enable coatings to obtain new functions: the hardness of nano-coatings is extremely high, which is more than three times the hardness of tool and mold steel ;The coating is fine and smooth, and the friction coefficient between it and the carbon material is small; the coat...

AI Technical Summary

Problems solved by technology

In the current production process, the temperature of the four walls of the kneading equipment is relatively high, and the external temperature of some kneading pipes is relatively high. There is a large heat loss in the kneading process, which causes the kneading process to be unstable and affects the quality of carbon products.

[0008] 2. Especially in winter, the northern regions such as Xinjiang and Qinghai are relatively cold, which intensifies the heat dissipation of the kneading equipment. In order to achieve the predetermined kneading temperature, the kneading time needs to be extended appropriately. Even so, it is still lower than the control temperature requirement, causing kneading. While the unstable production process affects the quality of carbon products, the production capacity of the kneading pot is reduced by at least 10%

[0009] 3. During the kneading process, the materials are being mixed with extrusion and separation (kneading and blending), accompanied by physical phenomena such as mixing, loosening, and friction. The material is a compound movement during the kneading process. The lining and mixing blades of the equipment have different degrees of wear and tear. It is necessary to repair and replace the lining and mixing blades of the kneading equipment on a regular basis, which virtually increases the production cost and the impact of the output of the enterprise.

[0010] 4. During the mixing movement of the paste in the kneading equipment, it will form sticky lumps in the dead corners such as the mixing knife and the inner lining. After falling off and mixing into the paste, quality defects such as cavities and interlayers will be formed in the carbon block, which will seriously affect product quality

[0011] 5. At present, the widely used thermal insulation material rock wool products are produced with basalt, dolomite, etc. as the main raw materials. The shedding and replacement of rock wool during use will cause environmental impact. Inferior rock wool will also cause fires, which do not meet low-carbon requirements. , energy saving and emission reduction trends are facing unprecedented development opportunities and challenges
