As an important industrial raw material, crush glass plays a key role in different production fields. According to different uses, glass sand can be divided into many types, of which crushed mirror glass and ordinary glass sand are the two most common types. Although their basic raw materials are similar, due to differences in application requirements, there are significant differences between the two in terms of quality, particle size, purity, etc. Today, this article will focus on explaining the main differences between crushed mirror glass and ordinary glass sand.
1. Differences in use
Crushed mirror glass chips are mainly used in the production of architectural glass, automotive glass and other high-precision glass products. It has high requirements for the transparency, surface smoothness and strength of the glass, so it requires specific physical and chemical properties to ensure the high quality of the finished glass. Ordinary glass sand is usually used in the production of general glass products, such as window glass, packaging glass, etc., with relatively low requirements, mainly focusing on cost control and basic glass performance.
2. Particle size and uniformity
Crushed mirror glass has very strict requirements on particle size. It needs to have a uniform particle size distribution to ensure that the glass is heated evenly during the production process, so as to achieve the best physical properties. Too large or too small particles will affect the quality of the finished glass, especially in terms of transparency and surface smoothness. Ordinary glass sand has relatively loose requirements for particle uniformity. Although there are certain particle size standards, the difference is obvious compared with crushed mirror glass.
3. Purity and chemical composition
The purity requirements for crushed mirror glass are usually higher. In order to ensure the transparency and impurity-free of finished glass, the chemical composition of crushed mirror glass must be strictly controlled, especially the content of metal oxides and iron ions. Iron ions have a great influence on the color and transparency of glass, so crushed mirror glass must be carefully screened and processed to remove these impurities. Ordinary glass sand has relatively low purity requirements because it is usually used for glass products that do not require extremely high transparency.
4. Production process and processing
Due to the higher requirements for crushed mirror glass, its production process is usually more complicated, involving multiple screening, washing and fine particle size control. These processes ensure that the quality of glass sand reaches high standards. The production process of ordinary glass sand is relatively simple, usually only requiring preliminary screening and washing, and the process requirements are relatively low.
5. Cost difference
Since crushed mirror glass requires higher purity and more delicate processing, its production cost is relatively high. Ordinary glass sand has less investment in the production process and relatively low cost. Therefore, the market price of crushed mirror glass is usually higher than that of ordinary glass sand.
Select clean mirror glass raw materials to make sure the purity of mirror glass aggregates. use high-tech crushing facility to guarantee the mirror glass chips keeping the mirror percentage at a higher level. Understanding the difference between the two will help to select the appropriate glass sand in practical applications, thereby improving production efficiency and product quality.
