Silicon gifda application field

The sealing end surface of the mechanical seal is composed of rotating dynamic ring installed on the axis and a static ring fixed on the machine seat. It requires good material wear resistance, low friction coefficient, corrosion resistance, high heating rate, strong seismic performance, siliconization, siliconization Graphite can meet these requirements. According to the determination, when the PV value (seal pressure and speed of the speed) reaches 147MPA · m/s, the hard alloy steel ring will generate thermal stress cracks, while the sealing ring of the silicon graphizer is 687MPa · m/ S instead of damage. It can also be used for water sealing such as shielding pumps and high -horsepower diesel engines. Siliconized graphitic can be used as bearing for pumps such as phosphate, phosphoricide and hydrofluoric acid. In addition, in the semiconductor industry, the heating tablets and fixtures of the growth of silicon extension and manufacturing artificial joints, artificial heart valve,

What are the reasons for the low initial efficiency of lithium carbide graphite negative electrodes

1. Low specific surface area: As you mentioned, the specific surface area of waste graphite is usually low, which leads to a decrease in the contact area between the electrolyte and graphite, affecting ion insertion and extraction during the initial charge and discharge process, thereby reducing the initial Coulombic efficiency. Compaction and coating treatment can increas

What are the factors that affect scales graphite quality?

The quality of scales graphite determines the product quality of the processed scale graphite powder. The scales graphite resources are natural graphite of the light crystal, which is formed by deteriorating quality under the action of long -term geology. The scales graphite crystals are scales -shaped. The scale of the scales of scales graphite and the amount of carbon content is the key factor affecting the quality of scales. The following editors will take you to understand:As the basic processing raw materials of various graphite powder products, the quality of scales graphite is an important condition. According to scales graphite quality, various parameters, etc., scales can be processed into graphite products such as scales graphite, ultra -fine graphite powder, high pure graphite, nanim graphite, colloid graphite and other graphite products. The scale size of the scales graphite determines the lubrication performance of processed. The larger the scale graphite size, the better

Antioxidant treatment methods for graphite materials

As is well known, during the manufacturing process of graphite products, the thermal decomposition and condensation of organic carbon based raw materials form porous artificial graphite materials, with a general porosity of around 20% to 30%. Most of them are open pores, which increases the diffusion speed and depth of oxidizing gases, and deteriorates their antioxidant pr

Mechanical performance of expansion graphite at different temperatures

Expansion graphite has excellent chemical stability, heat resistance, sealing, self -lubricating, radiation resistance and high heat -conducting. It is widely used in industrial fields such as machinery, oil, chemical, metallurgy, aerospace, navigation, transportation, and transportation. It is an ideal advanced sealing material. The mechanical property of expanded graphite may be different at different temperatures.1. Within the temperature range of 400 degrees Celsius, the compressed elastic modulus, rebound rate, and compression rate of expansion graphite sealing materials are not significantly affected by the temperature, and the impact is not greatly affected.2. There are significant differences in the compression modulus, rebound rate, and compression rate of two samples made of different materials formulas and processes, and there are also appropriate differences in the compression strength.3. Within the temperature range from room temperature to 400 degrees, the pressure resis
