Upgrading of domestic manufacturing industry drives demand growth in abrasive paste industry

Abrasive paste is an important grinding and polishing product made from a mixture of abrasives and media. It is mainly used for grinding and polishing non-ferrous metals, glass, ceramics and other products. Its application fields include automotive parts, medical equipment, glass, ceramics, aerospace , national defense and military industry, etc. Abrasive pastes are divided into corundum-based abrasive pastes, diamond-based abrasive pastes, etc. Among them, diamond-based abrasive pastes are currently the mainstream.

Based on the importance of abrasive paste in material processing, precision machining, molds and other fields, many domestic and foreign institutions and scholars have carried out extensive research work. Many domestic universities and institutions have achieved good results in abrasive modification and slurry preparation. Hua Yong and others from Zhengzhou University discussed the application of modified silicon carbide powder in abrasive tools and provided many methods for powder modification to improve performance; Wang Sen conducted in-depth research on the preparation and performance of diamond abrasive products. After modifying nanodiamond micropowder with Span 60, abrasive products with excellent suspension performance were prepared by optimizing the dispersion process and dispersion medium; the research group of Ji Xiaoli and Wu Qide of Wuhan University of Technology studied the modification of silicon carbide and the dispersion and suspension of slurry. Careful work and exploration have been carried out in terms of its properties; the Hubei Provincial Institute of Chemistry has developed a new gel-like water-based anti-rust grinding fluid with high suspension and high dispersion capabilities. Its outstanding feature is that it can handle large particle sizes (W40-50) The abrasive has excellent suspension and dispersion capabilities, and the suspension rate can be maintained above 80% for 24 hours, but its oxidation stability needs to be improved.

According to the “China Abrasive Paste Industry Market Survey Research Report 2022-2026” released by the Industrial Research Center, from 2017 to 2019, Driven by the development of downstream industries such as advanced manufacturing, the domestic abrasive paste industry demand has maintained a growth trend, and the industry market size has also maintained a growth trend. In 2020, affected by the COVID-19 epidemic, the domestic abrasive paste market shrank slightly. In 2021, the domestic abrasive paste market will achieve substantial growth, with the market size exceeding 150 million yuan.

From the perspective of the number of enterprises, the number of enterprises in my country’s abrasive paste industry is relatively large, and the industry concentration is low; from the perspective of enterprise types, domestic large-scale abrasive paste enterprises are dominated by joint ventures or wholly foreign-owned enterprises. Typical enterprises such as Zhengzhou Abrasives and Grinding Tools Cutting Research Institute Co., Ltd., Beijing Guorui Sheng Technology Co., Ltd., etc.; from the perspective of technology and technology, although domestic production technology has been greatly improved, there is still a large gap with developed countries such as the United States and Japan, resulting in some domestic advanced Foreign technology is still used in formulas or production equipment; from a product perspective, domestic research on abrasive pastes mainly focuses on oil-based systems, while the advantages of water-based abrasive pastes are increasingly recognized.

Industrial researchers believe that in the future, the abrasive paste industry still has certain development potential, mainly reflected in the growing demand for high-end abrasive pastes . As my country transforms from a “manufacturing power” to a “manufacturing power”, the domestic manufacturing industry will further consolidate the advantages of traditional manufacturing through the transformation and upgrading of traditional manufacturing, and gradually form and enhance advanced manufacturing capabilities through technological innovation. Transformation, upgrading and advanced manufacturing have increasingly higher requirements on the processing accuracy and surface integrity of parts and products, which will inevitably promote the development of abrasive pastes in the direction of high efficiency and precision, thus promoting the continuous improvement of the technical level of the abrasive paste industry.
