Quartz sand filter material is used to intercept suspended matter in the water and floating matter on the water surface during the water treatment process. Just like water penetrates into the ground through sand and gravel, it blocks the suspended matter in the water. , mainly for those fine suspended solids. This plays a role in purification and filtration. Ordinary quartz sand is used in sewage treatment and has a service life of three to five years. Fine quartz sand is specialized in pure water treatment and has a service life of one to two years. It is better to replace it in time. The water quality will not be as good as before.
Due to its unique physical and chemical properties, quartz sand plays an important role in aviation, aerospace, electronics, machinery and today's rapidly developing industries, especially its internal molecular chain structure, The crystal shape and lattice change rules make it have high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and unique optical properties. It plays an increasingly important role in many high-tech products. effect.
