Silicon Nitride Ceramic:
Every year, 40 million tons of waste plastics accumulate in the environment around the world, and about 2 million tons of waste plastics are thrown into the environment every year in China. Take agricultural film for farmland as an example. The annual output of agricultural film in my country reaches one million tons, and it is increasing at a rate of 10% per year. No matter what crops are covered, all film-covered soil has residual film. According to statistics, the annual residual amount of agricultural film in my country is as high as 350,000 tons, and the residual film rate is 42%. A large amount of residual film remains in the 0-30 cm of farmland. In other words, nearly half of the agricultural film remains in the soil, and food safety is a huge hidden danger. "Plastic is completely assimilated by microorganisms in the soil, degraded into CO2 and water to achieve inorganic mineralization, which may take 200-400 years, resulting in accumulation in the environment." Professor Yang Jun told the Yangcheng Evening News reporter. Tenebrio molitor is also called breadworm. In insect taxonomy, it belongs to Coleoptera, Paediaceae, and Mealworm genus (Paediata). Originally produced in North America, it was introduced to China from the former Soviet Union in the 1950s. Tenebrio molitor is known as the "protein feed bank". Its dry product contains 30% fat and more than 50% protein. In addition, it also contains phosphorus, potassium, iron and other elements. Dry Tenebrio molitor larvae contain about 40% protein, pupae contain 57%, and adults contain 60%. In China, Tenebrio molitor is actually similar to silkworms. It can be eaten directly by humans, fried or used as feed. Tenebrio molitor feeds on scorpions, centipedes, geckos, snakes, tropical fish and goldfish, which not only grow fast and survive. The rate is high, and the disease resistance is strong, and the fertility is greatly improved. It is very easy to breed yellow mealworms. Farmers can breed fresh oats, wheat bran, and apples.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
