先進セラミックスにおける粉末の重要性
Powders are crucial for advanced ceramics. This is evident in how people define advanced ceramics. The general definition of advanced ceramics is: they use high-purity, ultra-fine, man-made or selected inorganic compounds as their raw materials. They have precise chemical compositions, manufacturing, and processing methods. They also have a precise structural design. They have excellent mechanical, acoustic, optical, and thermal properties. Ceramics have electrical, biological, and other properties. They are either oxides or non-oxides. They are made from metals (like Al, Zr, and Ca) and non-metals (like O, C, Si, and B). They consist of ionic bonds and covalent bonds. Coordinated bonded ceramic materials. Chemicals have two crucial components. They are […]
石英粉末、タルク粉末、高カルシウム粉末の類似点と相違点は何ですか？
What distinguishes talc powder, quartz powder, and heavy calcium powder? Firstly, there is a significant difference in feel between the three. Talc powder has a more delicate and smooth texture. Talc, quartz, and heavy calcium powder are non-metallic minerals. They are crucial for both the industry and commerce. They are primarily used as filler. They can be used in ceramics, glass, paints, coatings, and other industries. Talc powder Talc powder consists of magnesium oxide, silicon oxide, and hydrogen oxide. Its chemical formula is Mg3[Si4O10](OH)2. It has a specific gravity of 2.7-2.8 and a hardness of 1. It resists corrosion, heat, acid, and alkali. It has strong adsorption, insulation, and a […]
Production technology of heavy calcium carbonate powder for breathable membranes
What is calcium carbonate used in breathable membranes? What are the production difficulties? What is a breathable membrane? A breathable film is microporous. It lets water vapor through but obstructs liquid water. It is primarily used to make health products. It also makes breathable, rainproof cloth and other products. It is used in various fields such as medicine, health, personal care, construction, and agriculture. It is also used in sideline product packaging. It is also widely used in other fields. Why does the breathable membrane use calcium carbonate? What kind of calcium carbonate is used? Breathable film production starts by filling polyester with inorganic fillers, mainly calcium carbonate. Then, a […]
改質炭酸カルシウムの用途は何ですか？
Modified calcium carbonate is calcium carbonate (CaCO3) that has been treated to improve its properties for specific uses. Calcium carbonate is cheap, abundant, and non-toxic. So, it is used in many industries. These include construction, plastics, rubber, pharmaceuticals, and food. Calcium carbonate’s modification mechanism has two types. One is chemical action, the other is physical action. Surface chemical effects, such as substitution, polymerization, grafting and hydrolysis of functional groups. The filler causes surface effects like adsorption, coating, and infiltration. These effects happen at the phase interface. When the filler is completely wetted, it causes physical adsorption. This happens on the high-energy surface of calcium carbonate. The energy there is higher […]
API粒子径制御におけるジェットミルの応用例
In recent years, research and drug processing have changed. They used to focus on pharmacology but now aim to improve drug effects. Development will focus on refining drug particles. It will make them ultrafine, purify them, and add functions to them. Research and applications are focused on particles below the submicron level. The pharmaceutical industry has much literature. It shows that finely ground drugs are good for human absorption. They also act faster in the body and are used more by the body. We use size reduction technology to improve powder processing. It can boost the bioavailability of active pharmaceutical ingredients (APIs). This helps the drugs have their desired effects. […]
ジェットミルの詳細説明：幅広い用途
In recent years, with the recognition of ultrafine particle superiority, more and more researchers have begun to attach importance to micro powder manufacturing research. Jet mill technology, an important method for preparing ultrafine powder, has become one of the preferred methods for developing high-performance micro powder materials. Characteristics of jet mill Jet mill, also known as airflow mill or jet pulverizer, is a machine that uses high-speed airflow to crush materials and impact components through collisions, impact, shear, and other effects. The product produced by crushing the material with an airflow mill has uniform fineness, a narrow particle size distribution, high purity, a smooth surface of particles, regular shape, and […]
PVCの改質には、どの炭酸カルシウムを使用すればよいですか？
Polyvinyl chloride (PVC) is a cheap and readily available polymer material with a wide range of applications in industries such as footwear, pipe fittings, wire, cable, and calendered films. However, the poor toughness and lack of thermal stability of pure PVC materials have limitations in many applications. Therefore, in many industries, PVC composites modified with various fillers have been developed to improve their mechanical properties and thermal stability. For instance, by adding a certain amount of calcium carbonate (CaCO3), the hardness of PVC products has been improved, resulting in improved performance and production costs can be controlled. As research continues, it has been found that the ease of processing calcium […]
マイクロシリカ粉末、シリカ粉末、石英粉末、白色カーボンブラックの違いを区別できますか？

After many industry experts’ generous advice, the editor finally has a clear understanding of these concepts. Overall, it is more valuable to distinguish from the preparation industry and application fields. Of course, there are also senior technical experts who told the story of the origin of the name, which is indeed eye-catching and meaningful. Microsilica powder: Generally collected through smoke and dust, it contains a certain amount of silica dust. Silica powder: In the industry, ultrafine powder obtained by grinding quartz ore with corresponding purity […]
炭酸カルシウム粉末とタルク粉末の特性の類似点と相違点
Calcium carbonate powder and talc powder are both non-metallic mineral powders. They have similarities and differences. Let’s learn more about them. Introduction to talc and calcium carbonate powder Talc is a type of magnesium silicate mineral, belonging to the trioctahedral minerals. Its structural formula is (Mg6)[Si8]O20(OH)4. Talc is generally found in the form of lumps, blades, fibers, or radial, with a slippery feel. It has a low hardness and high melting point. Talc has good insulation for both electricity and heat, low swelling and shrinking power, high dispersibility, good covering power, good oil absorption and hydrophobicity, great slipperiness, small friction coefficient, stable chemical properties, and resistance to acid and alkali […]
