Classification of fly ash and its role in cement
Classification of fly ash is an important process in understanding its properties and potential applications in various industries. Fly ash is a byproduct of burning coal in power plants. It can be categorized by its chemical composition, physical traits, and reactivity. Fly ash, as an industrial by-product, is closely related to the combustion of coal. It mainly comes from the power, heat, and supply industries. It also comes from other industries that use coal-fired facilities. Fly ash mainly contains SiO2, Al2O3, Fe2O3, CaO, SO3, Na2O, K2O, and carbon. It has a porous structure and is volcanically active. Fly ash can be divided into many types based on its source and […]
How to control each link in the production of spherical silicon powder?
Spherical silicon powder has high purity and very fine particles. It has good dielectric properties and thermal conductivity. It also has a low expansion coefficient. It is widely used in packaging, aerospace, coatings, medicine, and cosmetics. It is an irreplaceable filler. There are two methods to prepare spherical silicon micropowder: a physical and a chemical method. The main methods are: flame, deflagration, high-temp melt spray, plasma, and self-propagating low-temp combustion. The chemical methods include: gas phase, liquid phase (sol-gel, precipitation, microemulsion), and chemical synthesis. In making spherical silicon micropowder, strict control of each step is key. It ensures the product meets quality standards. Spherical Silica Powder Raw Material Control Factors […]
リチウム電池材料価格の高騰：間近！
Lithium batteries, particularly lithium-ion batteries, are composed of several key materials that contribute to their performance, energy density, and safety. What is the current production status of the lithium battery materials industry? Since August, the lithium battery material industry’s production has improved. Data shows a 10% month-on-month increase in output. The leading companies have now reached full production. Some companies are not at 100% capacity. But, the industry’s operating rate is high. Some small and medium-sized enterprises may have an even higher rate. However, the actual capacity utilization rate may be higher than the reported 60%. It is expected to rise to about 63 to 65 in November. Are there […]
シリカ粉末の分散性に最も大きな影響を与える改質剤はどれですか？
Silica powder’s dispersibility is its ability to be evenly suspended in a medium, like a liquid or polymer. This property is crucial in various applications, including coatings, adhesives, plastics, and pharmaceuticals. The dispersibility of silica can be influenced by several factors: Silane coupling agent is a unique, low molecular weight organosilicon compound. Its chemical structure usually contains two functional parts: one end is a hydrolyzable alkoxy group (such as methoxy or ethoxy) that can react with the surface of inorganic materials, and the other end is an active functional group with affinity to organic polymer materials (such as amino, vinyl, epoxy, etc.). This unique design allows silane coupling agents to […]
バッグ式集塵機の現場設置工事計画は、主に以下の手順から構成されます。
The on-site plan for installing the bag dust collector includes these steps: 1. Equipment inspection and acceptance: Before installation, inspect the bag dust collector. Check that its appearance, size, and model meet the design requirements. Also, ensure its internal components are intact. At the same time, the equipment needs to be tested to ensure that it is stable and reliable. 2. Foundation construction: Select the right foundation type and specs for the bag dust collector based on its size and weight. The foundation must be strong and stable. It must not let the equipment tilt or shift during operation. After the foundation is built, it must be inspected. This is […]
炭酸リチウムの価格が8万元/トンを突破！
On November 11, lithium carbonate futures soared to 80,000 yuan/ton. As of the close of the day, the main LC2501 contract closed at 80,950 yuan/ton, up 4.32%. At the same time, trading volume and open interest rose sharply. The lithium carbonate index added 60,300 lots, a record high. Yu Shuo, an analyst at Chuangyuan Futures, believes that lithium carbonate futures broke through 80,000 yuan/ton. Multiple favorable factors caused this. On one hand, the favorable macro policies boosted power battery use. It exceeded expectations. On the other hand, with the results of the US election, subsequent tariffs may increase. Domestic battery factories have boosted production to increase exports. The Spring Festival […]
カルシウム粉末残留物含有量がPVC製品の加工性および性能に及ぼす影響
Calcium powder residue content greatly affects PVC (polyvinyl chloride) products. It impacts their mechanical properties and overall quality. Calcium carbonate is a common PVC filler. It is key to their properties. Impact on the appearance of PVC products Excessive calcium powder residue may cause the gloss of PVC products to decrease, and the color to be dark and uneven. Large particles or irregular calcium powder flakes in the residue form bumps or dents on the surface of PVC products. This affects their appearance quality. Impact on the physical properties of PVC products 1. Hardness and heat resistance: Calcium powder can improve the hardness and heat resistance of PVC products. But, […]
非金属鉱物粉末の表面改質方法
Surface modification is key to improving non-metallic mineral powders. It enhances their properties and applications. Non-metallic minerals, like talc, kaolin, and calcium carbonate, are used in many industries. These include plastics, paints, ceramics, and pharmaceuticals.

This can improve their performance, compatibility, and functionality. There are many methods for surface modification. Methods that can change the surface of non-metallic mineral powders are called surface modification methods. These include: Now, the main methods for surface modification of non-metallic mineral powders in industry are: Surface chemical coating (1) Surface chemical coating […]
ジェットミルはどのようにして低い粉砕温度を維持するのですか？
Jet mills are specialized devices for grinding materials. They are used where fine particle sizes are needed. A key benefit of jet mills is their ability to keep a low grinding temperature during milling. This is crucial for materials that can be sensitive to heat, such as pharmaceuticals and certain chemicals. Mechanisms for Low Grinding Temperature in Jet Mills Airflow and Particle Acceleration High-velocity air: Jet mills use fast jets of compressed air or gas to accelerate particles toward each other. This acceleration creates kinetic energy. It causes impact comminution. This method reduces particle size without generating much heat. Cooling effect: The fast-moving air helps grind the material and cool […]
