The rapid development of the new energy industry, especially the vigorous rise of the electric vehicle industry, has brought new growth points to the powder coating industry. As a key material, the quality of power battery insulation powder is directly related to the safety performance and service life of the battery. Yantai Wanheng Intelligent Equipment Co., Ltd. (hereinafter referred to as "Yantai Wanheng") relies on its advanced technical strength and rich industry experience to provide front kneading equipment for foreign customers specializing in power battery insulation powder, which significantly improves the effect of powder. Recently, Yantai Wanheng has launched two low-temperature powder equipment to help the high-quality development of the powder coating industry.

In the production of powder coatings, particle size control is a key technology, which is directly related to the quality and performance of the coating. For special purpose powder coatings such as insulating powder, the consistency of particle size is particularly important. In order to obtain a powder with a more concentrated particle size distribution, it is recommended to use a double separation mill for processing. This mill can effectively reduce the particle size span, while removing most of the micro-powder with a diameter of less than 10 m, ensuring that the content of micro-powder in the final product does not exceed 0.1, avoiding the blockage of the fluidized bed during the dip coating process, thus making the coating more uniform and improving the coating quality.

It should be emphasized that because the insulating powder usually contains silicides, it not only increases the possibility of wear on the production equipment, but also may cause the metal content to exceed the standard. In order to solve this problem, Yantai Wanheng suggested that materials with high wear resistance, such as 6542 steel or tungsten carbide treated materials, should be used in the manufacture of screw elements, gear rings, grinding discs, striking columns and other key components. These materials can not only withstand the wear challenges brought by silicides, but also extend the service life of equipment, ensure the continuity of production and the stability of powder coatings.

In addition, the performance of the extruder also plays a key role in the quality of the powder coating. Li Zong, head of Yantai Wanheng, disclosed to the paint purchasing network that the key components of the extruder, including screw barrel, screw accuracy, clearance fit, operating speed, material, self-cleaning ability and screw arrangement, are all important factors affecting the quality of powder paint. Aiming at the production of low temperature curing powder coatings, Li specifically pointed out some challenges. Because the resin softening point and curing temperature of this kind of coating are low, the reaction speed is fast, the traditional extruder heating plate is difficult to achieve uniform temperature distribution. When the screw is operated at high speed, the generation of local friction may cause coking of the powder particles.

In order to overcome these problems, Yantai Wanheng designed a low-temperature curing twin-screw extruder with a length-to-diameter ratio of about 11D, which can reduce the reaction time of the material. Its screw speed is 200-300 rpm, and there is no heating plate. The necessary heat is generated through the friction between the screw and the material, so that the material produces a physical reaction. The ratio of screw top diameter to root diameter is about 1.43, which increases the surface area of the screw and improves the dispersion ability per unit length. In addition, the screw extends from the gear box to the front end, and is cooled by cooling water, which accurately and effectively controls the temperature of the material to ensure the stability of the production process and the high quality of the powder coating.

Thanks to the professional technical research and development team that has been engaged in milling equipment for many years, Yantai Wanheng has intelligently transformed powder equipment and applied for more than 30 patents. It not only provides a single equipment, but also provides customers with process design of the production line. The one-stop service from equipment manufacturing, installation and commissioning to follow-up technical support ensures that customers can achieve production goals quickly and efficiently, while greatly reducing operating costs, increased market competitiveness. Its equipment products are sold to more than 30 provinces and cities in China and exported to South Korea, Saudi Arabia, Pakistan, Vietnam, India, Iran, Russia and other countries and regions, and have won praise and trust from users at home and abroad. In order to better serve customers, Yantai Wanheng has set up after-sales service teams in Guangdong, Jiangsu, Zhejiang and other places. The existence of these after-sales service teams ensures that customers can obtain timely and effective technical support and services, and further enhances customer satisfaction.

Yantai Wanheng knows that in order to further promote the development of the powder coating industry, it is particularly critical to strengthen cooperation and exchanges within the industry. Therefore, we actively participate in the forums and conferences of the major powder coating industry, share experience and exchange technology with colleagues in the industry through these platforms, and discuss the future development trend of the industry, and jointly provide suggestions for the innovation and progress of the industry. These exchanges and cooperation not only inject new vitality into the powder coating industry, but also bring new opportunities and challenges to the development of Yantai Wanheng itself.

With its professional ability in the field of chemical equipment manufacturing and continuous technological innovation and product upgrading, Yantai Wanheng has successfully walked in the forefront of the industry in the list of technology-based small and medium-sized enterprises. Yantai Wanheng's efforts and achievements have not only created huge economic value for customers, but also set a new benchmark for the technological progress and industrial upgrading of the entire powder coating industry.
