Scale graphite is a non -metallic mineral with unique physical chemical properties such as high temperature resistance, antioxidant, corrosion resistance, heat shock, high strength, good toughness, high self -lubricating strength, high heating, and strong conductivity. Graphite series products are mainly used for metallurgy, machinery, electronics, battery, chemical, light industry, military, defense, aerospace, fire -resistant materials and other industries. Scales graphite is an important non -metallic material for modern high -tech.
What are the characteristics of scales graphite? Let ’s take a brief understanding.
The scales are thin and tough, with excellent materialization performance, and have good conductive conductive heat shock resistance, sexual corrosion resistance, etc.
What is the application of scales graphite? Let ’s take a brief understanding.
1. Fire resistance material. Scales graphite can be widely used for structural refractory materials and coatings that can be used to treat the gold industry, such as magnesium carbon bricks, 坩埚, etc. The smelting industry's desulfurization promoter, the pencil core of the light industry, the carbon brush of the electrical industry, the electrode of the battery industry, the catalyst of the fertilizer industry, etc. The scales graphite can be produced in depth, and graphite can also be produced for lubricants, molding agents, brushes, and conductive coatings. This utility model can also produce expansion graphite, for the raw materials for flexible graphite products, such as flexible graphite seals and flexible graphite composite materials.
2. Coatings. Scales graphite can be used as the function of Chinese coatings. The filler is mainly used for anticorrosive coatings, fireproof coatings and conductive coatings.
Anti -rust primer and carbon black, talc powder, oil, etc. have good chemical resistance and solvents corrosive; adding chemical pigments such as zinc to the formula, the rust -proof effect is better.
Expanded graphite is an inter -graphite compound made of natural graphite scales through chemical or electrochemical treatment, and it is a fireproof filler. Under heated conditions, the volume of the expansion graphite rod can suffocate the flame sharply, and at the same time generates the swelling material, to obtain the effect of isolation of the flame, delay or interrupt the flame spread, and it is not burning, good soft, high in appearance, and good in charcoal layer. However, it is appropriate to choose the volume and amount of the expansion body. Tests show that 150um particles, 30%expansion multiple, and 5%dosage are the most suitable.
Scales graphite rods can be directly used as carbon conductive fillers, and can also be made into composite conductive fillers for conductive paint. However, due to the large amount of graphite scales, the performance of the coatings will be brittle and it can make its application development restrictions at a certain time. Therefore, the corresponding measures are taken to further develop the conductivity of graphite, and effective methods reduce the addition of graphite scales. The Tianhua Chemical Engineering Institute developed high -temperature corrosion -resistant resin as the substrate. It uses large -like graphite scales as the main aggregate. It has strong electrostatic ability, high body strength, and good abrasion resistance.

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.
Expanded graphite was discovered at the beginning of the 1860s, and many countries like to use it for research, which can achieve many unexpected results. How many times can expansion be magnified? That's right. It's twice as big or even times! It is a new carbon material! Many people don't know much about expanded graphite!
The colloidal graphite powder produced by graphite manufacturers has good lubrication performance, high conductivity to price ratio, and catalytic reaction characteristics. At the same time, it has very high ductility and can be used to produce various commodities. Colloidal graphite powder is commonly used as a conductive electrode for lead-acid batteries, a positive and negative conductive agent for high-capacity lithium batteries, and a raw material for heat-resistant lubricants.The companies that graphite manufacturers often use colloidal graphite powder are as follows:1. Good lubrication characteristics, commonly used as a mold lubricant in the production process of organic fertilizers and metal catalysts in agriculture and animal husbandry.2. It can withstand temperatures up to thousands of degrees Celsius and is often used as a heat-resistant lubricant material and a corrosion-resistant lubricant material.3.
