黒鉛化と炭化の違いは何ですか？
The difference between graphitization and carbonization lies in their processes and outcomes in the treatment of carbon-containing materials. Carbonization is the thermal breakdown of organic materials without oxygen. It produces a carbon-rich char. This process typically occurs at lower temperatures and focuses on removing volatile components. In contrast, graphitization transforms carbon into graphite. It uses a high-temperature treatment, usually above 2500°C. This improves the carbon’s structure and conductivity. Carbonization makes a carbonaceous solid. Graphitization yields a crystalline carbon. It is suitable for advanced materials and electronics. Graphitization and carbonization both convert carbon-containing materials into a form of carbon. But, there are key differences between the two processes: What is Graphitization? […]
How to grind electrolytic aluminum slag into powder
Aluminum slag is made during the electrolytic production of aluminum. Carbon slag contains a large amount of fluoride salt (about 70%, mainly cryolite). If it is discarded as waste, it will not only cause the loss of fluoride salt. This will also increase the use of fluoride salt and pollute the environment. To keep regenerated cryolite pure, and to ensure a high recovery rate, the carbon powder and cryolite must be very pure. The fineness should be above 200 mesh d85%. Use the equipment for closed-circuit grinding. So, how to grind electrolytic aluminum slag into powder? 1. First, prepare the raw materials. Crush the electrolytic aluminum slag into small pieces […]
5種類のケイ酸塩充填剤がコーティングに及ぼす様々な影響
Pigments and fillers have a basic job. It is to give the coating a certain color. They also add hiding power, chemical resistance, and other properties. Inorganic fillers, also called body pigments, do not have the tinting and hiding ability of coloring pigments. This is because their refractive index is like that of film-forming substances. However, they can thicken the coating by filling it. They also play a skeleton role in the coating. They make the coating full and thick. This reduces the cost of coating production. In coating applications, fillers fall into five types. They are: carbonates, silicates, silicon dioxide, barium sulfate, and aluminum hydroxide. This division is based […]
二酸化チタンのコーティングにおける性能応用
Titanium dioxide is an inorganic white pigment. Its main component is titanium dioxide. It can be divided into three types according to its crystal form: brookite, anatase, and rutile. It is used in coatings, plastics, papermaking, and ink. The largest use is in coatings, which make up about 60% of the total. This is due to its advantages. These materials have a high refractive index. They also have strong color power and whiteness. They are non-toxic and stable. It is used in both solvent-based and water-based paint. If titanium dioxide is used, it has several roles. It covers and decorates. More importantly, it improves the paint’s physical and chemical properties. […]
真空ローダーの搬送要件は何ですか？
They mainly move powder and granular materials. Examples include API powder, chemicals, metal oxides, and explosive powders. They also move capsules, tablets, pills, small food particles, and explosive particles. They cannot move very wet, sticky, or heavy materials. Not all materials can be fed with vacuum feeders. To find out if materials can be moved, we must measure and analyze their key traits. Characteristic parameters include: stacking angle, stacking density, particle factor, electrostatic constant, moisture sensitivity, explosion risk, toxicity, and corrosiveness. (1) Bulk density Bulk density refers to the weight of a material per unit volume in a loose state. Particles or powders contain material and air. So, their bulk […]
