Application of flake graphite in the coating industry

As a functional filler for coatings, flake graphite is mainly used for anti-corrosion coatings, fireproof coatings, and conductive coatings.As a anti-corrosion material, it is made with carbon black, talc powder, and oil as an anti rust primer, which has good resistance to chemical and solvent corrosion. If chemical pigments such as zinc yellow are added to the formula, its anti rust effect is better.The expandable graphite used as a fireproof filler is a graphite interlayer compound obtained from natural graphite flakes through chemical or electrochemical treatment. Under heating conditions, the expandable graphite rapidly expands in volume (up to 300 times), suffocating the flame and generating an expanding substance to isolate the flame, delay or interrupt the flame spread. It is also non combustible, has good softness, and has high surface energy, The carbonization layer has good strength. However, the volume and dosage of the expansion body should be selected appropriately. Exper

How to choose the scale of scales graphite size

Scales graphite has good conductivity and thermal conductivity. It is widely used in sealing, lubrication, metallurgy, chemical industry and other industries. Different industries have different requirements for the specific parameters of scales graphite. Choosing the correct graphite graphite is closely related to its effect. Today, I will explain the correct method of choosing the graphite size of the scale:1. The effect of scale graphite particle size on expansionThe degree of particle size on the expansion of scales also has a certain effect. After experiments, the expansion rate of scales graphite is directly proportional to the particle size of graphite. The expansion graphite has a rich pore structure. The smaller the grain size of the graphite. The smaller, the lower the expansion coefficient, and vice versa. Therefore, in the fields of sealing and fire -resistant coatings, large -scale scales should be selected as materials.2. The effect of scale graphite particle size on smo

Graphite mineral classification

Graphite's process characteristics are mainly determined by its crystallization form. Crystal forms of graphite minerals have different industrial values and uses. Industry, according to the different crystals, divide natural graphite into three categories.1. Deep crystalline graphiteThe dense crystal graphite is also called block -like graphite. Such graphite crystals are obviously visible to the naked eye. The diameter of the particles is greater than 0.1 mm, which is concentrated in 0.1-1m/g than the surface area. This: Graphite is characterized by high quality. Generally, carbon content is 60-65%, and sometimes 80-98%, but its plasticity and slipperyability are not as good as scales.2. Scales graphiteGraphite crystals are scales; this is made of deterioration under high -intensity pressure, with large scales and fine scales. The characteristics of such graphite ore are not high, generally between 2 and 3%, or 10 to 25%. It is one of the best ore in nature. The floating, lubricabil

The main factors affecting the price of graphite molds are as follows

Several physical and chemical indicators that need to be understood when selecting graphite materials

Graphite is an allotrope of elemental carbon, where each carbon atom is surrounded by three other carbon atoms (arranged in a honeycomb like pattern with multiple hexagons) that are covalently bonded to form covalent molecules. Due to its excellent properties, graphite is used to make many materials. Below are several physical and chemical indicators that need to be understood when selecting graphite materials:1. Average particle diameter of the materialThe average particle diameter of a material directly affects its discharge condition. The smaller the average particle size of the material, the more uniform the discharge of the material, the more stable the discharge condition, and the better the surface quality. For forging and die-casting molds with low surface and precision requirements, it is usually recommended to use materials with coarser particles; For electronic molds with high surface and precision requirements, it is recommended to use an average particle size of 4 μ Mater

How to identify the quality of graphite board

The graphite board is not rusty for some manufacturers, but in fact many manufacturers have applied for more than ten years, and they are unclear how to distinguish the quality of graphite boards. This is only a kind of summary of the product, which is very vague.Speaking of how to distinguish the advantages and disadvantages of graphite boards, there is only one key, which is the relative density. The following discusses the necessity of using the Moore quality formula from many levels.The battery electrolyte is very prone to infiltration, resulting in the oxidation of the graphite board air, which is greatly shortened by the use period. The density is high, and the cost of application is increased, so it is important to choose a suitable graphite board manufacturer.2. In the field of resistance, the key to the graphite board is used to pad the method, which has a moisturizing effect. The relative density of the graphite board here is greatly displayed.

Insufficient technical investment in domestic graphite powder production enterprises

As a policy of each graphite deep processing production company, it is far from reality. The single product function is not bad, but the stability of batch production is doubtful, and the consistency of each batch of products cannot be guaranteed. A professor of deep processing and production of graphite powder believes that the exchanges of different types of different types of information for the deep processing and production of graphite powder will be a long process. The gap between many companies is that they have excellent experiments but cannot produce in batches. The following editors analyze the reasons for the lack of technical investment in domestic graphite powder production enterprises:It is not related to the automation control of the company's production line, which is a systematic problem. At present, graphite powder deep processing production equipment accounts for more than half of the imported equipment. Graphite mineral resources are a very important strategic reso
