Mineral pigments are inorganic. They are a type of inorganic matter and are colored. There are two main sources. One is from natural ores. They are made through beneficiation, crushing, grinding, grading, and refining. It is mainly used for paintings, handicrafts, antiques, and cultural relics restoration. Another source of inorganic pigments is pigments made from natural minerals. They are chemically treated after being mined. Material introduction We develop modern mineral colors from ancient ones. They maintain several ancient mineral colors. They have made huge strides in varieties. In particular, ore minerals have developed from several types of mineral colors. To hundreds of species. In terms of earth pigments, water-dry colors […]

Stone paper is a new material that is similar to paper and plastic. It can replace some functional and professional papers. It can replace most plastic packaging. It is both cost-effective and recyclable. It saves users a lot of money without causing pollution. Material introduction Stone paper is made from limestone, a mineral with abundant and widespread reserves. It is the main raw material. It is 70-80% calcium carbonate. Polymer is an auxiliary material that makes up 20-30% of the material. It utilizes the principles of polymer interface chemistry. It has the traits of polymer modification. It is made by polymer extrusion and blow molding after special processing. The powder […]
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 […]
