The maximum heat resistance of the resin is 180 ℃. High temperature resistant materials can be prepared by using DP resin of A-step phenolic resin as impregnant. Porous carbon is pre impregnated with high melting point polytetrafluoroethylene paraffin, and the optimum temperature is 315-327 ℃. Then it is impregnated with low melting point polytetrafluoroethylene paraffin,

Graphite can be used as sealing and lubricating materials, and is widely used in many cement rotary kilns. The utility model has two main purposes: one is used for sealing the kiln head and kiln tail, and the other is used for lubrication between the carrier wheel and the wheel belt. The graphite products used

The anti-oxidation coating graphite electrode produced by graphite electrode manufacturers refers to the graphite electrode coated with an anti-oxidation protective layer (graphite electrode antioxidant). The anti-oxidation coating forms a protective layer that can conduct electricity and resist high temperature oxidation, which can reduce electrode consumption (19% – 50%), prolong the service life of graphite electrode

Mother’s Day originated in America. On May 9, 1906, Anna Jarvis’s mother died in Philadelphia. She was very sad. On the anniversary of her mother’s death the following year, Miss Anna organized an activity to remember her mother and encouraged others to express their gratitude to their mothers in a similar way. Since then, she

At present, many enterprises engaged in solar photovoltaic industry join in the production of monocrystalline silicon. Due to different industries, some enterprises lack of relevant knowledge about how to use graphite materials correctly, so there are many problems in daily production. It is very important for us to understand and master the characteristics of graphite

In recent years, graphite column and graphene oxide (go) have been introduced into biosensors based on the principle of fluorescence resonance energy transfer (FRET). Fluorescence resonance energy transfer (FRET) refers to the transfer of energy between two fluorescent groups from the donor to the acceptor. FRET has become a powerful tool to detect the changes
