Surface modification is one of the key technologies to optimize the properties of inorganic powder materials
Surface modification is one of the key technologies to optimize the performance of inorganic powder materials (calcium carbonate, silicon micro powder, kaolin, talc powder, mica powder, graphite, etc.), which is very important to improve the application performance and value of inorganic powder. Why should the powder surface be modified? 1、 Present situation of inorganic powder […]
Calcium carbonate has become an important inorganic chemical raw material in the national economy
According to preliminary statistics in the industry, from the end of last century to the beginning of this century, the domestic annual production capacity of precipitated calcium carbonate has reached more than 8 million tons. Under the guidance of industry associations, domestic manufacturers have continuously popularized the calcium carbonate production process technology, continuously improved the […]
The influence of “one belt, one road” on the powder industry is immeasurable.
The president of People’s Republic of China one day attended the summit one of the “one belt, one road” International Cooperation summit and delivered a keynote speech on the 14 th. One belt, one road, one belt, one road, has been built. We must take the opportunity to move forward and push forward the construction […]
How does the powder industry break its cocoon and regenerate under the environmental storm
Since 2016, starting from the environmental storm, an unprecedented tide of price rise and bankruptcy has swept the country. In the general environment, inorganic non-metallic powder industry, as the most basic raw material for industrial manufacturing, is no exception. With the national environmental protection supervision successively stationed in various places, the environmental protection regulation of […]
New situation of foreign exchange earning control over the export of raw materials of mineral resources in China
At the tense moment when the WTO initially ruled that China’s export of raw materials of mineral resources violated the regulations, the Ministry of mineral resources gradually led the “domestic lime powder production conference” in Shanghai on September 5. The conference was led and led by the Ministry of mineral resources. More than 200 representatives […]
The transformation of the development of mining machinery industry
At present, China’s policy adjustment in mineral mining and resource utilization has increased the cost of mineral development and utilization, which has brought great turbulence to the market of mineral grinding equipment. At the same time, it also puts forward new requirements for the performance and production cost of grinding equipment and other equipment. The […]
Global graphite consumption structure, trade pattern and application trend
The world is rich in natural graphite resources. According to the statistics of USGS (U.S. Geological Survey), in 2015, the global proven natural graphite reserves were about 230 million tons, of which 98% were concentrated in Turkey, Brazil, China and India, with reserves of 90 million tons, 72 million tons, 55 million tons and 8 […]
Purpose and method of pressing graphite material for graphite processing
At present, most carbon and graphite products are produced by extrusion. Molding method is often used to produce cold pressed graphite with small size or products with fine structure. Sometimes prebaked anode is also pressed by backlog method. Today, north electric carbon graphite processing introduces the purpose and method of graphite material pressing. The pressed […]
Latest market of graphite
The graphite market soared all the way, and the price finally stabilized at the end of August. At present, the 19th national congress is about to be held. The mine explosives in Jixi and Luobei, Heilongjiang Province are stopped, resulting in a slight rise in graphite in Northeast China. The shutdown of flake graphite and […]
The production process of heavy calcium carbonate is mainly divided into dry process and wet process
Calcium carbonate, also known as grinding calcium, is a powder product with natural calcite, heavy calcium carbonate, limestone and chalk as raw materials and reaching a certain fineness through mechanical crushing and grinding. It is generally called fine grinding calcium carbonate (FGCC) in the world. Heavy calcium carbonate is divided into coarse ground calcium carbonate […]
Role of heavy calcium powder in various industries
In recent years, due to the improvement of environmental protection awareness, the state has vigorously advocated environmental protection, and its ore processing has reached an economic climax. As we all know, heavy calcium carbonate is referred to as heavy calcium for short. It is a white powder processed with high-quality calcite as raw material. Its […]
On the unknown characteristics of talc powder
What is talc? Talc powder is called pulvistalci in English. It is a white or quasi white, fine and non sandy powder with greasy feel. Odorless and tasteless. This product is insoluble in water, dilute mineral acid or dilute hydroxide alkali solution. Main ingredients: calcite, a compound, is neutral, basically insoluble in water and soluble […]
