In recent years, the development of the epoxy resin industry has made great progress, the industrial structure has been continuously optimized, the technology has made breakthroughs, and the application fields have continued to expand. On June 6, the "2023 China Epoxy Resin Exhibition" was co-sponsored by China Chemical Industry Information Center and Huangshan Municipal People's Government, undertaken by China Chemical Information Media Center and Huizhou District People's Government, and co-organized by Anhui Xinyuan Technology Co., Ltd. and Nanjing Forestry University. At the "Industrial Development (Huangshan) Conference", participating experts and representatives discussed new ideas on how to promote the green transformation of the industry and accelerate development.

Solder paste is a material used to connect the electrodes of the parts and the pads of the circuit board. The main component is a tin alloy. After sintering, it can play the role of conducting the electrodes of the parts and the PCB. Solder paste must be cooled to sinter, that is, it must go through reflow soldering; reflow soldering is a heating furnace, which can obtain the heat necessary for solder paste to assist solder paste sintering; solder paste is mainly used in the patch processing industry; it can save a lot Lower labor costs and improve production efficiency.

According to the "China Epoxy Resin Industry Market Research and Investment Evaluation Report (2023 Edition)" released by Limu Information Consulting, epoxy resin is a class of oligomers containing two or more epoxy groups in the molecule, which can be It can be used together with various curing agents such as amine, imidazole, acid anhydride and phenolic resin to form a three-dimensional network cured product.

On June 7, the 2023 China Epoxy Resin Industry Development (Huangshan) Conference continued. The participating experts pointed out that the way out for my country's epoxy resin industry in the future is to go out and realize internationalization, but first of all, it is necessary to practice basic skills. For enterprises, the next step is to refine the research and development of some new products and open up new application areas. For example, building repairs require qualified modified polymers, which is a huge market. 2023 is an important stage for the high-quality development and transformation and upgrading of the epoxy resin industry. The current complex and changeable international environment has brought multiple challenges to the sustainable development of the epoxy resin industry.

① LED outdoor and industrial lighting have high entry barriers and low industry concentration. In terms of market competition, it is mainly for home lighting and commercial lighting in the field of small and medium power LED lighting. There are many market participants and fierce competition in the industry. At present, leading companies such as Foshan Lighting, Opple Lighting, Sunshine Lighting, and Lidaxin have formed in the above-mentioned lighting field, and the market concentration is closer to the head.

Due to the requirement to use lead-free flux paste under different process conditions, the issue of cleaning process impact is being addressed more and more. In view of previous studies, the peak temperature of most alternative solder pastes is about 34 °C higher than that of tin-lead solder pastes, which may cause more oxidation and flux polymerization reactions, which make the flux residues in the soldering process. More of the medium is "baked" making it harder to clean.
