Laser particle size analyzer tests and controls the particle size of glass raw materials [Winner particles are launched on the New Third Board]

Jinan Winner Particle Instrument Stock Co., Ltd. is a high-tech enterprise integrating R&D, production and sales of particle testing related instruments and equipment. The company's predecessor was the Particle Testing Research Institute of Shandong Building Materials University. It has been researching laser particle size testing technology for more than 30 years since it began undertaking the National Seventh Five-Year Science and Technology Research Project in 1982. In order to pursue the company's long-term strategy and achieve greater space for leap-forward development. With the strong support of the Jinan City and High-tech Zone Governments in Shandong Province, Winner completed the restructuring of a joint-stock company in 2010 and passed the NEEQ listing evaluation process in 2013. In 2014, relevant departments approved our company as the first stock in China's particle testing industry, and approved our company's securities name as "Winner Particles" and the stock code: 430410.

Glass industry trends

The control of raw materials in the glass industry is divided into three aspects: first, the control of ingredients; second, control of batch materials; third, control of particle size, including restrictions on the largest particles, control of ultra-fine powder, and control of various particles. Level proportioning control. With the continuous development and progress of science and technology, the industry has become more and more aware of the impact of raw material quality on glass production. Among them, the control of particle size has been widely accepted and fully valued.

The impact of glass raw material particle size on production.

The control of raw material particle size includes three aspects: First, the upper limit of particles, which is the size of the largest particle allowed in the powder. Those exceeding the upper limit are called large particles. The presence of large particles can adversely affect melt quality. The second is the particle lower limit, which is the size of the finest particles allowed in the powder. Those smaller than the lower limit are often called fine powder. The third is particle gradation, which refers to the proportion of particles of various sizes in the powder. In addition, there are many small gaps between the fine powder particles, mixed with a lot of gas, occupying a certain space. These gas spaces will form a heat insulation layer, reducing the thermal conductivity of the mixture, thereby increasing the difficulty of melting and producing large particles. effect. At the same time, the existence of these gas gaps also reduces the wettability of the glass melt, which can easily lead to microbubbles in the product. Secondly, when the moisture content is high, the powder is easy to form egg-shaped fine powder clumps, which sometimes cannot be opened in the mixer, forming "egg" and causing the mixture to be uneven. Even powders with low moisture content can affect the uniformity of the mix due to the presence of excessive fines. In addition, the fine powder contains a lot of heavy refractory minerals, which can easily lead to more impurities and melting defects.

The particle size testing and control of glass raw materials can be monitored through the world's cutting-edge laser particle size testing method. WINNER2308 is a wet and dry integrated large-range laser particle size analyzer. It adopts a new generation design concept, successfully solves various technical problems of dry and wet integration, realizes dry and wet one-click switching, and integrates multiple patented technologies of Jinan Winner Company. . It adopts patented turbulent dispersion technology and utilizes the shearing effect of shock waves to fully disperse the particle samples, ensuring high test accuracy. It is the first choice partner and right-hand man for particle size testing related to the particle size of glass raw materials.

On the occasion of the renewal of everything in the New Year, "Winner particles" were listed on the National Equities Exchange and Quotations in Beijing on January 24, 2014. I would like to thank leaders, experts, enterprises, and friends for their long-term support and love for "Winner particles" over the years. Winner Particle Company will uphold its responsibility as the leader of China's particle testing technology and make persistent efforts to lead the development of new technologies in the domestic particle testing industry. Continue to make unremitting efforts for China's particle size testing technology to catch up with the world's first-class level.
