Silicon Nitride Ceramic:
Synthetic resin is the most important component of plastics, and its content in plastics is generally 40% to 100%. Because of the large content and the nature of the resin often determines the nature of the plastic, people often regard the resin as a synonym for plastic. For example, polyvinyl chloride resin and polyvinyl chloride plastic, phenolic resin and phenolic plastic are mixed together. In fact, resin and plastic are two different concepts. Resin is an unprocessed raw polymer compound that is not only used to make plastics, but also a raw material for coatings, adhesives, and synthetic fibers. In addition to a very small part of plastics containing 100% resin, most plastics require other substances in addition to the main component resin. Fillers are also called fillers, which can improve the strength and heat resistance of plastics and reduce costs. For example, the addition of wood powder to the phenolic resin can greatly reduce the cost, making the phenolic plastic one of the cheapest plastics, while also significantly improving the mechanical strength. Fillers can be divided into two types: organic fillers and inorganic fillers, the former such as wood flour, rags, paper and various fabric fibers, and the latter such as glass fiber, diatomaceous earth, asbestos, carbon black and so on. The content of fillers in plastics is generally controlled below 40%. Plasticizers, or plasticizers, can increase the plasticity and flexibility of plastics, reduce brittleness, and make plastics easier to process and shape. Plasticizers (plasticizers) are generally high-boiling organic compounds that are miscible with resin, non-toxic, odorless, stable to light and heat, and phthalates are the most commonly used. For example, in the production of polyvinyl chloride plastics, if more plasticizers are added, soft polyvinyl chloride plastics can be obtained, and if no or less plasticizers are added (amount <10%), hard polyvinyl chloride plastics can be obtained. .
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.
