Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
The research team gave the mechanism of the degradation of polystyrene by the yellow powder larvae: in the first step, the foam is chewed into small pieces by the yellow powder larva and ingested into the intestine; in the second step, the chewing effect increases the polystyrene foam and The contact area between microorganisms and extracellular enzymes, the ingested fragments are further depolymerized into small molecule products under the action of extracellular enzymes secreted by intestinal microorganisms; in the third step, these small molecule products are produced in a variety of enzymes and the enzymes of yellow powder larvae Under the action of the larvae, it further degrades and assimilates to form the larvae's own tissue; the residual foam fragments and some degradation intermediates in the fourth step mix part of the intestinal microorganisms and are excreted in the form of insect feces. Further continue to degrade. The plastic we usually use is not a single component, it is made up of many materials. Among them, high molecular polymers (or synthetic resins) are the main components of plastics. In addition, in order to improve the performance of plastics, various auxiliary materials, such as fillers, plasticizers, lubricants, and stabilizers, must be added to the high molecular compounds. , Colorants, antistatic agents, etc., can become plastics with good performance. Plastic additives, also called plastic additives, are compounds that must be added to improve the processing performance of the polymer (synthetic resin) or to improve the performance of the resin itself when it is processed. For example, in order to reduce the molding temperature of polyvinyl chloride resin, the plasticizer is added to make the product soft; another example is to add a foaming agent to prepare a lightweight, vibration-resistant, heat-insulating, and sound-insulating foam; The decomposition temperature is very close to the molding processing temperature, and molding cannot be achieved without adding heat stabilizers. Therefore, plastic additives occupies a particularly important position in plastic molding processing.
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.
