At the beginning of the month, the price of scales in Shandong was stable as a whole. At present, the mainstream price of -195 mainstream prices are 6300-6500 yuan/ton, which is the same as last month. Entering winter, most of the scale graphite companies in the Northeast are suspended for production holidays. Although a few companies are in production, the output is reduced and the inventory reserves are not much.
The scale of the scale graphite market has been poor some time ago and the demand for material resistance has declined, which led to a decline in the price of scales, and corporate quotations were chaotic. As the Spring Festival holiday approaches, due to the suspension of production in the Northeast region, graphite supply has declined, and downstream enterprises have been basically completed. The supply demand for scales graphite market is plain, and the offer is relatively stable.
In 2021, the export situation of scales was relatively sluggish. According to customs statistics, from January to January 2021, the total export of natural scales in my country was about 139,000 tons, a year-on-year decrease of 18.3%. Among them, the top five countries in exports are Japan, the United States, the Netherlands, Italy, and South Korea, and the export volume of five countries accounts for 55.9%of the total exports. According to statistics from the export port, Qingdao Customs exports 55,800 tons, Dalian Customs is 45,100 tons, and Tianjin Customs is 31,900 tons. The total amount of graphite exported from the above three customs accounts for more than 95%of the total export volume.
2023-03-28With the rapid development of the world industry, graphite graphite powder has been regarded as one of the important industrial mineral raw materials at home and abroad. Especially in recent years, the development of science and technology has played an important role in all walks of life.
Graphite powder is soft, black and gray; it is greasy and can pollute paper. The chemical properties of graphite powder are relatively stable at normal temperature, insoluble in water, dilute acid, dilute alkali and organic solvents; the material has high temperature resistance resistance, which can be used for refractory materials, conductive materials, and wear -resistan2023-03-28Preparation of ultra -fine graphite powder
2023-04-03In recent years, graphite molds have continued to impact model shell sales markets with their high -quality characteristics, and have become the new darling of the machinery processing industry. The manufacturers of Kobwee Grapeite products below told everyone that the shortcomings and preventive methods of the heat treatment process of graphite mold.

Flake graphite is widely used in high-grade refractory materials and coatings in the metallurgy industry. It is like fish phosphorus, belongs to hexagonal crystal system, and has a layered structure. Below, we will provide a detailed explanation of the key points to pay attention to when processing refractory materials with flake graphite.
The expansion graphite is a loose and porous worm -like substance prepared by the procedure of graphite scales through the intervening, washing, drying, and high temperature. When the expansion graphite encounters high temperature, it can instantly swell 150 ~ 300 times in volume, which changes from sheet to worm -shaped, thereby loose structure, porous and bending, expanded surface area, improved surface can be enhanced. In this way, it increases its softness, return elasticity and plasticity.The expansion graphite is widely used, and the main development directions are as follows:1. Granules expand graphite: Small particles expand graphite mainly refer to 300 purposes that can expand graphite, and its expansion volume is 100ml/g. This product is mainly used for flame retardant coatings, and its demand is very large.2. Expansion of the swelling temperature at height: The starting expansion temperature is 290-300 ° C, and the expansion volume is ≥230ml/g. This type of expansion graphi2023-02-09Graphite product form
