Application of quartz sand as a water treatment filter material
Because the quartz sand particles in the three-layer filter media filter bed are smaller than those in the two-layer filter media, and there is a layer of finer, heavy anthracite filter media below the quartz sand layer, under the same conditions, or even at a higher filtration rate, the water quality of the filtered water from the three-layer filter pool is better than that of the two-layer filter pool. When using quartz sand, try to use it in combination. The vast majority of wastewater treatment plants in China implement the Class B standard of the "Discharge Standard for Pollutants from Urban Wastewater Treatment Plants", while implementing the Class A standard can significantly "remove phosphorus and nitrogen" from wastewater, reducing pollution to the receiving water body, and the effluent can be used as reclaimed water.

Applications and Uses of Nano Calcium Carbonate
Characteristics of nano-active calcium carbonate: Compared with pure calcium carbonate, it has a narrow particle size distribution range, reduced water absorption, reduced oil absorption, and good affinity with resins, which helps to improve the tensile, compressive, and wear resistance of products. It shortens the melting time after mixing, reduces the equilibrium torque, has high dispersibility, is easy to color, and increases the surface gloss of the product. Uses of nano-active calcium carbonate: As a filler, it is widely used in rubber, plastics, wires and cables, and inks. Function of nano-active calcium carbonate: In the rubber industry, it can improve dispersion performance and demolding performance of products, increase the surface smoothness and flexibility of products, and improve the processing and physical and mechanical properties of products. In the plastics industry, it can improve the flexibility, strength, and stability of plastic products, improve processing performance, significantly increase the filling amount, and reduce mold wear. Calcium carbonate filled in plastics and rubber after surface treatment has significantly higher tensile strength and impact strength than the filling system of untreated calcium carbonate, and shortens the kneading time and improves production efficiency during processing. In cable products, it can improve electrical insulation performance, has moderate acidity and alkalinity, good compatibility with resins, can increase the filling amount, reduce costs, and is suitable for filling in PVC wire and cable materials. In high-grade inks, coatings, and paints, it has better dispersibility and stability, and can increase the gloss, transparency, and quick-drying properties of the product.

Common problems and solutions of calcium carbonate in plastics
The important role of calcium carbonate in plastics. China has become a major producer and consumer of plastic products. In 2006, the output of plastic products exceeded 40 million tons, ranking second in the world, and has maintained a double-digit annual growth rate for more than 20 years. It is foreseeable that with the increase in domestic consumption demand and the increase in exports to the international market as a global manufacturing base, the annual output of plastic products in China will continue to grow rapidly for a considerable period of time in the future. In the plastic processing process, in addition to synthetic resins as basic raw materials, the scientific, correct, and reasonable use of various additives and auxiliaries is undeniable, including

“Zixiang” brand CCS series products are nano-precipitated calcium carbonate powders that have undergone surface organic treatment. They are suitable for filling silicone sealants (including one- and two-component room temperature vulcanization silicone weather-resistant adhesives, structural adhesives), polyurethane sealants, and MS sealants. The CCS series nano-calcium carbonate has a regular crystal morphology and suitable particle size. The nano-calcium carbonate products are surface-treated with stearic acid, etc., and have a low oil absorption value. They can be quickly mixed with sealant resins and other auxiliaries, and have good dispersibility in sealants. CCS can give sealant products ideal rheological properties, tensile strength, elongation at break, elastic recovery rate, modulus, and interfacial adhesion.

Tremolite applications and processing requirements
Currently, wollastonite products can be divided into two major categories: acicular wollastonite and finely ground wollastonite. Acicular wollastonite is widely used in plastics, rubber, asbestos substitutes, paints and coatings, etc., while finely ground wollastonite is mainly used in the ceramic and metallurgical industries. Wollastonite can densify ceramic structures, improve mechanical strength, reduce the coefficient of wet expansion, improve the strength and molding quality of the坯体, reduce the firing temperature, shorten the firing cycle, and achieve energy saving and efficiency improvement. It is understood that wollastonite is used in the preparation of various electromagnetic, building and daily-use ceramics, accounting for 40%-45% of the world's total wollastonite consumption. Filler wollastonite is the most potential and has the highest added value,
