Application of Particle Size Analyzer in Controlling the Particle Size of Glass Raw Material Glass raw materials The control level of raw materials in the glass industry can be divided into three steps: First, the control of the ingredients, which includes the high grade of the raw materials, the stability of the ingredients and the stability of the water, etc.; The second is the control of the granularity, including the limitation on the largest particles, The control of ultra-fine powders and the control of the proportions of various particle grades; third is the control of batching materials, that is, through the control of the oxidation-reduction potential of the mixture, the melting, clarification and homogenization can reach a more scientific and reasonable state. . With the continuous development of industry technology, people have now become more and more aware of the impact of raw material quality on glass production. Among them, the control of raw material composition has been widely accepted and given full attention to, and to granularity. The control should also be an important topic. This is an important technological step that the glass industry must face now and must strive to leapfrog. Effect of glass raw material granularity on production Glass raw materials are mainly divided into raw materials and auxiliary raw materials according to their role in the glass. The main raw material is the main raw material for forming the glass structure, which determines the main physical and chemical properties of the glass. These raw materials will generate silicate after melting reaction and constitute the main body of glass liquid, such as silica sand and soda ash. Auxiliary raw materials used less, mainly to improve the glass melting, fining, forming properties or make the product has some special properties, such as adding Glauber's salt as a clarifying agent, adding carbon powder as a reducing agent, adding selenium cobalt as a colorant. The control of raw material granularity includes three aspects: First, the upper limit of the particle, that is, the size of the largest particle allowed in the powder, and the large size exceeding the upper limit. The presence of large particles can have a very bad effect on the melting quality. The second is the lower limit of the particle, which is the size of the finest particle in the powder, and it is often referred to as the fine powder. The third is particle grading, which refers to the proportion of particles in various sizes in the powder. A reasonable amount of particulate material will help improve the melting quality. At present, the general level of float production lines in the country does not attach much importance to the grain size of raw materials. Only the more advanced float glass production lines require strict requirements for siliceous raw materials, and the large particles are limited to smaller and smaller contents. Less and less. To achieve the goal of saving energy and reducing consumption, and improving the yield and quality of glass, we must first reasonably control the particle size of glass raw materials. If the large particles are too much, it will cause the glass to be difficult to melt, and eventually will form defects such as inclusions and affect the quality of the glass. There are many small gaps between the fine powder particles, which contain many gases and occupy a certain space. These gas spaces form a thermal insulation layer, which reduces the thermal conductivity of the mixture, thereby increasing the difficulty of melting and producing large particles. effect. At the same time, the presence of these gas voids also reduces the wettability of the glass melt and can easily lead to microbubbles in the product. Second, in the case of large water content, the powder easily forms olivary fine powder groups. This group sometimes cannot be opened in the mixer, and the formation of “material eggs†causes the mixture to be uneven. Even a powder with a lower moisture content will affect the homogeneity of the mixture due to the presence of too much fines. In addition, the fine powder contains many refractory minerals and it is easy to bring in more impurities and melting defects. Jinan micron particle size analyzer application WINNER2308 is a dry and wet integrated large-scale laser particle size analyzer. It adopts a new generation design concept and successfully solves the technical problems of dry and wet integration. It realizes dry and wet one-button switching and is very convenient to use. It integrates the Jinan Micron Corporation's A number of patented technologies, using Convergent-Light Fourier Transform patented technology and spectrum amplification technology, not only overcome the limitation of the scattering angle of the lens aperture, but also realize the large-scale expansion of the range in a limited space, and add multiple auxiliary integrated photoelectric detection. The device can effectively collect the scattered light at various angles corresponding to the test range to achieve the test accuracy and reliability in the full range. Using patented turbulence dispersion technology, the shear effect of shock waves is used to fully disperse the granular samples. The key parts of the disperse system are wear-resistant ceramics, which not only improves the service life but also guarantees testing. It is the first choice for industrial production quality control departments and research institutes with many kinds of particles and wide distribution of particles.
