Because graphite has many excellent properties, it is widely used in industrial sectors such as metallurgy, machinery, electrical engineering, chemical engineering, textile, and national defense. It can be used as refractory materials. Graphite products maintain the original chemical properties of flake graphite and also have strong self-lubricating performance. The characteristics of graphite powder are high strength and acid resistance, corrosion resistance, high temperature resistance of 3000℃ and low temperature resistance of -204℃. At the same time, its compressive strength is greater than 800kg/Cm2, and it is oxidation resistant. It loses 1% of its weight in the air at 450℃, and the rebound rate is 15 - 50% (density 1.1 - 1.5). Therefore, graphite products have now been widely used in metallurgy, chemical engineering, petrochemical engineering, high-energy physics, aerospace, electronics, etc.
Graphite's Functions and Advantages
1. Graphite products have good adsorption properties. The pore structure of carbon gives it good adsorption properties, so carbon is often used as an adsorption material to adsorb moisture, odors, toxic substances, etc. We have conducted experiments. The graphite grill pan used for grilling meat a few days ago looked very clean, but when placed on an induction cooker and heated, it could be seen that the grease and harmful substances adsorbed during the last grilling would slowly seep out. However, there is no need to worry. Just wipe it clean with a clean napkin and it can be used.
2. Graphite products have good thermal conductivity, fast heat transfer, uniform heating, and fuel saving. The grill pans and pots made of graphite heat up quickly, and the cooked food is heated uniformly, cooked from the inside out, and the heating time is short. Not only is the taste pure, but it can also lock the original nutrients of the food. We have conducted experiments. When grilling meat with a graphite grill pan, at the beginning, set the induction cooker to high heat, and it only takes 20-30 seconds for preheating. When starting to grill the food, just set it to low heat, which is conducive to saving energy.
3. Graphite products have chemical stability and erosion resistance. Graphite has good chemical stability at room temperature and is not eroded by any strong acids, strong alkalis or organic solvents. Therefore, even if graphite products are used for a long time, there is little loss. As long as they are wiped clean, they are as good as new.
4. Graphite products have a strong anti-oxidation and reduction effect. Products, especially graphite mattresses, can generate negative oxygen ions when heated, activating the surrounding items, maintaining human health, effectively preventing aging, and making the skin full of luster and elasticity.
5. Graphite products are environmentally friendly, healthy, free of radioactive pollution, and resistant to high temperatures. Carbon needs to undergo a graphitization process for at least a dozen days and nights in an environment of 2000 - 3300 degrees Celsius to become graphite. Therefore, the toxic and harmful substances in graphite have already been released completely, and it is at least stable within 2000 degrees Celsius.
