Laboratory and Chemical Applications
Quartz Frits are filter media made primarily from high-purity quartz sand or quartz powder, processed through a specialized manufacturing technique. They exhibit excellent chemical stability, high-temperature resistance, corrosion resistance, and high mechanical strength. Quartz frits are widely used in liquid filtration for various industries including water treatment, beverage, food, and pharmaceutical sectors. These filter plates can effectively remove suspended solids, oils, iron, manganese, algae, bacteria, and other impurities, improving water purity.
How it works
A quartz sand filter utilizes quartz sand as its filtration medium. Water flows through the quartz sand layer under gravity or pressure. Quartz sand possesses good mechanical strength and chemical stability, and its surface carries a negative charge, enabling it to adsorb positively charged suspended solids in water, such as silt, algae, and bacteria. Larger particles are intercepted at the surface of the sand layer, while smaller particles gradually penetrate into the sand layer, eventually being adsorbed and retained by the quartz sand, thus achieving water purification.

Frequently asked questions
Quartz glass is a hard and brittle material with excellent physical and chemical properties, extremely high mechanical hardness, good electrical insulation, high temperature and corrosion resistance, low and stable delay performance, good light transmittance, etc. It is widely used in semiconductors, optics, electricity, chemistry, aerospace, automobiles and other fields. Hard and brittle materials are difficult to process, and many fields urgently need cutting processes with small edge collapse, less material loss, low cross-section roughness, and a wide cutting thickness range. The traditional cutting method of quartz glass is mechanical cutting, that is, wheel cutting. Non-traditional cutting methods include water jet cutting, electrochemical discharge wire cutting, continuous laser cutting, etc. Mechanical cutting has low cost, but the contact between the wheel and the material causes large tool wear, and the material is easily contaminated by the tool. Quartz glass is prone to edge collapse, microcracks, and residual stress, which affects the strength and performance of the material! It is difficult to achieve curve cutting and requires post-processing, such as grinding and polishing. Laser cutting does not directly contact the material, has no contact stress, and can perform complex curve cutting. Picosecond laser has the advantages of small spot diameter, high precision, short action time with the material, and small action area, and is suitable for the processing of hard and brittle materials.
