Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
100 yellow mealworms can eat 34-39 mg of foam every day. During the 16-day test period, 47.7% of the insects ingested the foam and converted into CO2. The remaining (about 49.2%) is converted into biodegradable particles similar to rabbit feces and excreted. Tests with α-13C or β-13C labeled polystyrene plastic confirmed that it is mineralized into carbon 13 labeled carbon dioxide and lipids. The polystyrene foam in the intestine of the larvae degrades within 24 hours. The larvae that use styrofoam as their only food are as healthy as those that were fed normal food (wheat bran) after 1 month, and finally developed into beetle adults. Tenebrio molitor ate holes in the foam. After passing through the insect's intestine, the chemical structure and composition of the ingested foam change. Through the use of gel permeation chromatography (GPC), carbon 13 nuclear magnetic resonance spectroscopy, and thermogravimetric Fourier transform infrared spectroscopy, it was confirmed that the long-chain polystyrene molecules in the larval intestine were broken to form insect metabolites and excreted with feces. The experiment further successfully isolated a polystyrene-degrading bacterium, Exiguobacterium sp.YT2 (Exiguobacterium sp.YT2), which can use polystyrene as the sole carbon source for growth, from the larval intestine. This strain has been preserved in the General Microbiology Center of the China Microbial Culture Collection Management Committee and the National Gene Bank. It is the first polystyrene-degrading bacterium preserved in the culture center reported in the world.
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.
