The effect of expanding graphite on water pollution has a large number of research results. In terms of governing oil and organic pollution in the control of water bodies, expansion graphite is far more effective and economical than ordinary activated carbon now. But expansion graphite is inconvenient to transport and needs to be prepared at the application site. The preparation, use, recycling, and regeneration of expansion graphite environmental protection materials has certain technical difficulties. In addition, in the past, it did not attach enough attention to environmental protection, and the expansion graphite environmental protection materials have not been industrialized. The 18th National Congress of the Communist Party of China proposed to build a beautiful China and increased environmental protection, making the industrialization of expansion graphite environmental protection materials possible. The industrial foundation of expanding graphite environmental materials is now available, and this project can be performed from two technical levels.
In areas where water pollution companies, such as steel, chemical industry, printing and dyeing, food and other companies, build a service network for preparation, use, recycling, and regeneration of expansion graphite environmental protection materials. The cooperation of expansion graphite environmental protection materials and other governance methods will greatly improve the degree of treatment and benefits of water pollution. For increasingly frequent oil and organic water pollution pollution, build a comprehensive environmental protection ship for comprehensive waters, and combine traditional fences and absorbing methods with the efficient oil absorption performance of expansion graphite to improve pollution control.
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.
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.
