Overview
SGL graphite R6600 coating is used to treat graphite lubricated graphite bearings. Compression molding utilizes pressure equipment such as oil pressure, water pressure, or air pressure as kinetic energy, and steel molds as molds to form crucibles. Compared with rotational molding, it has the advantages of simple process, short production cycle, high yield, high efficiency, low labor intensity, less molding moisture, low crucible shrinkage and porosity, high product quality and density.
Product Details
SGL graphite R6600 coating treatment for graphite lubricated graphite bearings
Hongnaide isostatic pressed graphite is widely used in hard alloys (vacuum furnace heaters, sintering plates, etc.), mining (manufacturing drill bit molds), chemical industry (heat exchangers and anti-corrosion components), metallurgy (fixtures), machinery (mechanical seals), aerospace (nozzles, etc.), graphite piles (deceleration materials and reflective materials) and other fields.
Hongneide isostatic pressed graphite is a new type of graphite material developed in the 1960s, which has a series of excellent properties. For example, isostatic pressed graphite has good heat resistance.
In an inert atmosphere, its mechanical strength does not decrease with increasing temperature, but rather increases, reaching its highest value at around 2500 ℃.
Compared with ordinary graphite, it has a fine and dense structure and good uniformity. It has a very low coefficient of thermal expansion and excellent thermal shock resistance.
It is isotropic, with strong chemical corrosion resistance, good thermal and electrical conductivity, and excellent mechanical processing performance.
The production cost of graphite from Zhejiang Hongnaide is low, with the price of graphite of the same volume being only 25% of that of copper electrodes.
Processing speed, 3-5 times faster than copper electrodes, with no burrs after processing, and a discharge speed about twice that of copper. High processing accuracy, high processing precision, thermal expansion coefficient is 1/4 of copper.
The weight is 1/5 of copper, which is more suitable for making large electrodes.
High temperature resistance, the ignition point of graphite is 3650 degrees Celsius, and copper is 1083 degrees Celsius. It does not deform under high temperature conditions and is suitable for processing bone electrodes. Adhesive properties, broken graphite can be bonded with conductive adhesive to save costs.
Zhejiang Hongnaide's lightning protection graphite sheet is a key component in electronic equipment lightning protection. Its function is to limit the instantaneous overvoltage entering power lines and signal transmission lines within the voltage range that the equipment or system can withstand, or to discharge strong lightning current into the ground, protecting the protected equipment or system from damage caused by impact. The use of graphite sheet as a lightning arrester for discharge gaps has the advantage of large discharge current (up to 100KA).

Hongnaide selects high-quality PAN based graphite felt, which is bonded, cured, formed, and high-temperature graphitized through special processes. Carbon cloth can be attached to the surface according to customer requirements Charcoal paper or a combination of both can prevent fuzzing, resist airflow erosion, and increase strength.
Hongnaide graphite rollers are mainly used in industries such as glass fiber drawing machines, solar energy, metallurgy, electronics, and light bulbs. In glass fiber drawing machines, graphite rollers are used to collect glass fiber fine yarn products, which have the characteristics of high strength, good thermal shock resistance, good self-lubricating properties, high temperature resistance, corrosion resistance, and strong oxidation resistance, and are widely used in these industries.
Hongnaide graphite sintering machine is a product made by lathe processing technology for sintering positive electrode materials and high-temperature carbonized negative electrode materials. Graphite bowls have the characteristics of low thermal conductivity, high temperature resistance, thermal shock resistance, long service life, and strong corrosion resistance. Graphite crucibles are widely used in semiconductor, photovoltaic, chemical, industrial, smelting and other fields.
The affinity between Zhejiang Hongnaide graphite bowl and most media is very small, so dirt is not easily attached to the surface. Specially used for condensing equipment and crystallization equipment.
Zhejiang Hongnaide's various types of carbon and graphite firing boxes have excellent corrosion resistance to all concentrations of hydrochloric acid, phosphoric acid, and (including fluorine-containing media). The highest application temperature is 350 ° C-400 ° C, which is the temperature at which carbon and graphite burning boxes begin to oxidize.
The operating temperature of an impermeable graphite crucible depends on the type of impregnating material. For example, phenolic resin impregnated graphite can withstand temperatures between 170-200 degrees Celsius. If an appropriate amount of silicone resin is added to impregnate graphite, it can withstand temperatures up to 350 degrees Celsius. When phosphoric acid is deposited on carbon and graphite, it can enhance the antioxidant function of carbon and graphite crucibles and further increase the actual operating temperature.
The Hongnide graphite crucible also has good thermal conductivity. In non-metallic materials, the thermal conductivity is only higher than that of metals. The thermal conductivity is twice that of carbon steel and seven times that of stainless steel, making it suitable for use in heat transfer equipment.
