The high-end development of the grinding wheel industry has broad development space for the composite binder market

Composite and high-end are the development trends of the binder market. Composite binders have the advantages of ceramic, resin, metal and other binders, and there is broad room for market development in the future. The function of the bonding agent is to bond the abrasive grains to form a grinding wheel. As one of the key manufacturing raw materials of grinding wheels, the amount and performance of binder play a key role in the softness/hardness, service life, self-sharpening, shape retention, grinding ability and other properties of the grinding wheel.

There are many types of bonding agents, mainly divided into ceramic, resin, metal, rubber and other types. Among them, ceramic bonding agent is the most commonly used bonding agent for grinding tools. Each single bond has its own advantages and disadvantages. Specifically, ceramic bonding has good self-sharpening properties, but is brittle and fragile; resin bonding has good impact resistance, but has poor wear resistance, alkali resistance, and heat resistance; metal bonding has The agent has high strength and good wear resistance, but poor self-sharpening properties. With the expansion of application fields, single binders are gradually unable to meet market demand, and the market attention of composite binders has increased accordingly.

Composite bonding agents are one of the research hotspots in the field of bonding agents. At present, they are mainly divided into metal/ceramic composite bonding agents (metal as the main body), resin/metal composite bonding agents (resin as the main body), and ceramic/metal composite bonding agents (ceramics as the main body). as the main body) and other types. The composite bond has excellent properties, such as long life, good self-sharpening, and high processing quality. It has broad application prospects in the fields of thinning grinding wheels, diamond grinding wheels, ultra-thin grinding wheels, refractory materials, photovoltaics, aerospace, automobiles, etc.

According to the “2023-2028 China Composite Binder Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center In the semiconductor wafer thinning process, the grinding wheel involves rough grinding, semi-fine grinding, fine grinding and other processes. Currently in the international market, wafer grinding wheels are used by suppliers such as Japan’s Okamoto TSK, Japan’s DISCO, and the United States’ REVASUM. The grinding wheels are all produced using composite bonding agents.

my country’s grinding wheel production scale is huge, and there are many companies in the industry, including Jiangsu Zhengwei, Zhejiang Yida, etc. In 2022, the output of my country’s grinding wheel industry will reach about 258,000 tons, and the market size will exceed 5 billion yuan. At present, ceramics are the main binder for domestic grinding wheels, but domestic grinding wheels are mostly concentrated in the mid- to low-end fields. Under the background of domestic substitution and manufacturing upgrading, domestic grinding wheels will continue to develop in the direction of high-end, and the application of composite binders will follow. Released, the industry development prospects are very broad.

Industry analysts said that composite binders have broadened the application scenarios of traditional binders and are used in semiconductors, photovoltaics, automotive glass, and aviation. Driven by the upgrading of aerospace and other industries, the composite binder market has broad development prospects. The production of composite binders is in line with the high-end development trend of binders, and also meets the needs of industrial upgrades such as grinding wheels and diamond grinding wheels. It is expected to become a mainstream product in the market in the future.
