Factors affecting the impregnation effect of graphite

The factors that affect the impregnation effect include: firstly, the impregnation process conditions (such as temperature and pressure), and secondly, the physicochemical properties of the impregnation.Influence of process conditions(1) Temperature (product preheating temperature, impregnation tank temperature, impregnation agent temperature), depending on the impregnation process: 1. The product is preheated too high and is prone to oxidation; The temperature is too low, and when it comes out of the preheating box, it quickly cools down and enters the impregnation tank. When the impregnating agent encounters cold products, its viscosity increases and its fluidity deteriorates, resulting in poor impregnation effect. 2. If the tank temperature is too high, asphalt is prone to oxidation condensation reaction, viscosity will also increase, and flowability will deteriorate; The tank temperature is too low, the fluidity of asphalt is also poor, and the impregnation effect is not ideal.(2)

Introduction to the use of expansion graphite

The expansion graphite was discovered in the early 1960s. Many countries like to use it to study, so that many unexpected results can be achieved. The so -called expansion can be increased by more? That's right, more than double or even double! It is new carbon material! Many people don't know much about expansion graphite!Graphite crystals are two -way large -molecular layer -like structures. The C atom in each plane is combined with the C -C co -price bond, and the layer is combined with weaker Van Dehua.The layered structure of graphite is very typical. Each layer is a carbon atomic layer. The carbon atom in the layer is a strong covalent bond with SP2 hybrid orbit, that is, 1 2S electronics and 2 2P electronic hybridization, etc. The hybrid track of the price is located on the same plane and forms σ bonds each other, while the two unsteady 2P electrons are perpendicular to the plane to form a two -key π. This layered structure of graphite makes a certain gap between layers. Theref

Graphite flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

Introduction to carbon elements

Carbon is a very common element that exists in the atmosphere and crust in many forms. Carbon monouples have been recognized and used for a long time. A series of carbon compounds -organic matter is the foundation of life. Carbon is one of the ingredients of raw iron, cooked iron and steel. Carbon can form a large number of compounds in chemical self -combination, which is an important molecule in biology and business. Most molecules in organisms contain carbon.Existing formThe form of carbon existence is diverse, including crystalline single -quality carbon such as diamond and pulse graphite; there are fordless carbon and coal; there are complex organic compounds such as animals and plants; carbonate such as marble. The physical and chemical properties of single carbon depend on its crystal structure.
