The cryptocrystalline graphite crystal is extremely small, so it is also called microcrystalline graphite. Graphite particles are often embedded in clay , and separation is difficult. Due to the high grade of ore (generally containing 60% to 80% of carbon), many graphite mines directly produce crushed ore and sell graphite powder products. Hunan Lutang Graphite Mine established flotation plant flotation microcrystalline graphite in the 1950s, but stopped production due to high cost. At present, some units are still conducting research on new microcrystalline graphite flotation processes (such as oil agglomeration flotation).
The high-molecular polyolefin smoke material from Japan is non-toxic, highly elastic, highly breathable and washable. It is widely used in mattresses and cushions in Japan to replace the environmentally friendly and unwashable foam cotton latex and other cushion materials.
