The silicon wafer cutting fluid/cutting fluid market continues to expand, and the industry needs to accelerate transformation and upgrading in the future.

Silicon wafer cutting fluid, also known as silicon wafer cutting fluid, refers to a type of important auxiliary materials and consumables used in the photovoltaic solar silicon wafer cutting process. It mainly plays the roles of dispersion, suspension, lubrication, cooling, etc., which can improve cutting efficiency and reduce The purpose is to reduce cutting consumption, improve cutting accuracy, and ensure silicon wafer yield and quality.

According to different components, silicon wafer cutting fluid can be divided into two categories: oily silicon wafer cutting fluid and water-based silicon wafer cutting fluid. Oil-based silicon wafer cutting fluid is mainly composed of mineral oil, which is flammable, pollutes the environment greatly, and requires an alkane solvent to clean the silicon wafer; water-based silicon wafer cutting fluid has no pollution to the environment, and does not require a fixed solvent to clean the silicon wafer. wafers, in line with the current increasingly upgraded environmental protection requirements, it has gradually become a mainstream product in the silicon wafer cutting fluid market.

According to the “China Silicon Wafer Cutting Fluid/Cutting Fluid Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center shows that under the current background of vigorous development of the domestic photovoltaic industry, the increasing demand for silicon wafer processing has driven the scale of silicon wafer cutting fluid to continue to expand, and the industry shows good development prospects. According to data from the Ministry of Industry and Information Technology, domestic photovoltaic silicon wafer production will reach 357GW in 2022, a year-on-year increase of 57.5%. Against this background, my country’s silicon wafer cutting fluid market size will reach 320 million yuan in 2022, a year-on-year increase of 5.4%.

The viscosity of silicon wafer cutting fluid, the particle size of silicon carbide powder contained, and the impurity content are key factors affecting the yield and quality of photovoltaic silicon wafers. In the current context of the continuous development of photovoltaic silicon wafers in the direction of thinning, in order to meet the production requirements of ultra-thin silicon wafers, silicon wafer cutting fluids need to be continuously upgraded in the direction of high purification and customization in the future. At the same time, against the background of the gradual rise in the domestic photovoltaic cost reduction and efficiency improvement trend, recyclable silicon wafer cutting fluid will be one of the important directions for the future development of the industry.

There are many companies in the domestic silicon wafer cutting fluid market, including international companies such as Evonik of Germany, DISCO of Japan, Versum Materials of the United States, and UDM Systems of the United States, as well as Tianjin Mingyao Technology, Shuyang Zhongneng Silicon Industry, Liaoning Aoke Chemical, Jinan Culunte Technology, Guangdong Xinmingyang Technology, Qingchuan Huanyu Electronics, Shenzhen Frank Technology, Weifang Zhongzheng Photovoltaic Technology and other local companies.

Industry analysts said that silicon wafer cutting fluid is indispensable in the production and processing of photovoltaic solar silicon wafers Auxiliary materials and consumables are currently expanding in scale, driven by the booming development of the domestic photovoltaic industry, and the industry shows good development prospects. There are a large number of silicon wafer cutting fluid manufacturers in my country, but domestic products are mostly mid- to low-end products. High-performance, highly purified, and high-end silicon wafer cutting fluids are still highly dependent on imports. In the future, local companies will need to continuously improve their technical level and promote Domestic industries are accelerating their transformation and upgrading.
