粉体塗料の用途と開発動向に関する簡単な考察
With the push for environmental protection, firms must develop eco-friendly coatings. But, eco-friendly coatings aren’t limited to water-based ones. If enterprises rush to develop water-based coatings, product homogeneity will inevitably occur. Besides water-based coatings, high-solid, solvent-free, and powder coatings are also eco-friendly. They should be the key development focus of the coatings industry. A report said the Asia-Pacific region will have the highest growth in powder coatings from 2017 to 2022. This applies to both value and volume. Powder coating technology is developing rapidly to adapt to the demand-driven market. The market drives the need to study different powders in coatings. Powder Coating Overview Introduction to Powder Coatings Powder coating […]
石灰岩はどのようにして複数の変質を遂げるのでしょうか？
Limestone is a sedimentary rock composed mainly of calcite (calcium carbonate CaCO3). It usually forms in marine or lake environments. Biological and chemical processes cause it to precipitate. The characteristics and types of limestone are as follows: Color: generally gray, white, yellow, brown, etc., depending on the impurities contained. Texture: The texture is uniform and fine, but there are also cases of fossils or other rock fragments. Structure: It can be granular, mud-crystalline, bioclasts, etc. Hardness: Mohs hardness is about 3, relatively soft. Solubility: It is easily soluble in acid and will produce carbon dioxide bubbles. Limestone can be processed into various products, per different standards. These products are widely […]
ジェットミル粉砕法を他の粒子径縮小法と比較した場合の主な利点は何ですか？
Jet milling is a highly effective technique for particle size reduction that offers several distinct advantages compared to traditional milling methods. It is better than traditional methods like ball mill, air classifier mills, or hammer milling. How Jet Milling Works The jet mill is an advanced particle size reduction device. It has a unique working principle and structure. Its working principle is based on the energy conversion of high-speed airflow. The high-pressure gas, usually compressed air or inert gas, is sped to supersonic speed through the nozzle. This forms a high-speed airflow beam. The material is fed into the airflow. The high-speed airflow causes collisions and friction. It drives the […]

Advanced ceramics excel in many properties. They have mechanical, acoustic, optical, thermal, electrical, and biological qualities. They are used in high-end tech fields like aerospace, electronics, and biomedicine. They are also used in advanced manufacturing. There are many types of advanced ceramics. Each type has its own traits. For example, alumina ceramics resist oxidation. Silicon nitride ceramics are strong and resist electrical corrosion. Zirconium oxide ceramics are tough and biocompatible. High purity alumina High-purity alumina (4N and above) has many advantages. It is very pure, hard, and strong. It resists high temperatures and wear. It also has good insulation and stable chemical properties. Its high-temperature shrinkage is moderate. It has […]
硫酸バリウムの粒子サイズは、コーティングにどのような影響を与えますか？
Barium sulfate, as an inorganic pigment, is widely used in the coating industry. It reflects well at 300-400 microns. It prevents light aging from damaging the paint film. It is an efficient white matte stabilizer. Its unique needle-like crystal structure gives it excellent matte properties. It can also enhance the coating’s leveling. Also, barium sulfate’s low oil absorption and high filling content make it a cheap coating. Barium sulfate is the main body pigment, at up to 70%. Precipitated barium sulfate is vital in coatings. Precipitated barium sulfate can significantly improve the performance of coatings: 1. Increase density: Precipitated barium sulfate has a high specific gravity. It can raise the […]
粉体供給装置の分類と用途の紹介
Powder feeding equipment is vital. It conveys powder materials to the production process, accurately and evenly. Feeding equipment is vital to the silo system. It also conveys materials over short distances. Due to different purposes of use, it is also called a feeder, a feeder or a discharger. It is usually installed at the silo’s discharge port. It relies on the material’s gravity and the feeding equipment’s mechanism to discharge the silo’s material. It then feeds it continuously and evenly to the next equipment. The key role of the feeding equipment is to control the material flow. It must provide accurate feeding. In addition, when the feeder stops working, it […]
微粒子アルミナ粉末の凝集現象を改善するにはどうすればよいでしょうか？
Small particle alumina powder has unique properties. It is used in ceramics, chemicals, electronics, and other fields. However, in practical applications, small-particle alumina powder is prone to agglomeration. Agglomeration is when powder particles stick together and form larger clumps. This can happen during the storage, transport, or use of powdered materials. This affects its performance. Agglomeration can lead to poor powder fluidity and reduced dispersibility, affecting product quality. Basic characteristics of small particle size alumina powder Appearance and properties: Alumina powder is a white or slightly colored powder. It has a high melting point, high hardness, and good wear and corrosion resistance. Its density is about 3.97g/cm³, and the particle […]

Barite is the most common barium mineral. It is barium sulfate. It is often found in low-temperature hydrothermal veins, like quartz-baryte and fluorite-baryte veins. It is often associated with galena, sphalerite, chalcopyrite, and cinnabar. Most barite deposits in my country are in Hunan, Guangxi, Qinghai, and Jiangxi. They are mostly huge hydrothermal single mineral veins. Also, barite can form in sedimentary rocks, showing a nodule-like form. It is often found in sedimentary manganese deposits. It is also in muddy and sandy sedimentary rocks in shallow seas. In weathered deposits, it is often covered by residual clay. It appears in a nodular or blocky form. One of the applications of barite […]
Comparison between ball milling and high-speed airflow method
Comparing the ball milling method and the high-speed airflow method, which one is more suitable for the preparation of fine powders? To compare the ball milling and high-speed airflow methods for making fine powders, we can analyze several key aspects in detail. Precision and particle size control High-speed airflow impact method: This method can achieve finer, more uniform particles. It does so by precisely controlling the airflow’s speed, collision frequency, and time. It is ideal for fine powders with strict size limits. These are used in electronics and pharmaceuticals. Both demand high standards for powder size and shape. Ball milling method: The particle size can be controlled by adjusting the […]
