Quartz sand, as an important mineral raw material, is widely used in materials science and industry. As a unit for measuring particle size, mesh number is directly related to the chemical properties of quartz sand and its application in different industries. Mesh number, also known as particle size or sieve mesh, is an internationally accepted method for indicating the particle size of materials. It refers to the number of mesh holes per inch (25.4 mm) on the sieve. The larger the mesh number, the smaller the aperture of the sieve, and the finer the particles of the sieved and graded materials.

Industry application fields of quartz sand with different mesh numbers

The mesh number of quartz sand generally refers to the size and uniformity of the sand particles. Common mesh numbers include 4-6 mesh, 10-20 mesh, 20-40 mesh, 30-60 mesh, 40-70 mesh, 60-140 mesh, 120-200 mesh, etc. For example, the quartz sand used in common construction industries is mostly between a few meshes and hundreds of meshes, while high-end electronic materials, optical glass and other industries may use ultra-fine high-purity quartz sand with thousands of meshes.

1. 8-16 mesh quartz sand has larger particles and is often used in industrial fields such as casting, spraying, and sand making. Among them, 8-12 mesh quartz sand is suitable for polishing and abrasives of building materials such as stone and cement, and 16 mesh quartz sand is mostly used for polishing and cleaning in industries such as machinery manufacturing and precision casting.

2. 30-60 mesh quartz sand has more uniform particles and is often used in the manufacturing of high-end materials such as glass and ceramics. Among them, 40-60 mesh quartz sand is suitable for sand core materials in the fields of casting and chemical industry, which can effectively improve the high temperature resistance of the product.

3. 80-100 quartz sand is often used in common abrasive applications in the fields of construction and paint, which can effectively improve the surface gloss and quality. In addition, it can also be used to prepare plastic and rubber products with smooth and hard surfaces.

4. 120-270 mesh quartz sand has very fine particles and is often used in the manufacturing of high-precision fields such as electronic materials and semiconductors. Among them, 220-270 mesh quartz sand is often used as a polishing material, which can produce high-precision mirrors.

The mesh number of quartz sand is closely related to the application industry. As an important indicator to measure the particle size of quartz sand, the mesh number has a profound impact on the application range of its physical and chemical properties in different industries. Quartz sands of different mesh numbers have unique properties and advantages, and they play an important role in different industries. Therefore, when selecting the mesh number of quartz sand for screening, it is necessary to accurately control the mesh number of quartz sand for screening and grading according to specific application requirements and process conditions, so as to achieve better use results and improve product quality and production efficiency.
