Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramics:
The general development trend of China's plastic products industry is: agricultural plastics (including agricultural mulch, water-saving agricultural equipment and geosynthetics) still occupy an important position and will be further developed, Our Silicon Nitride Ceramic Plunger and Ceramic Plunger are expected to improve the efficiency and reliability of agricultural machinery and contribute to the sustainable development of the industry; packaging materials and plastic building materials will be the rapid growth of the plastics industry Main areas: high-tech, high value-added engineering plastic products and composite materials, the production and application fields will continue to expand with the development of the market economy; the production of pipes, profiles, calendered products, biaxially oriented materials, films, etc. Gradually develop in the direction of economic scale; in order to protect the ozone layer, foam plastic production will undergo fluorine-free technological transformation; in order to reduce environmental pollution, the recycling of waste plastics and the research and development of degradable plastics will be strengthened; in order to develop varieties of plastic products and improve the grade, plastic The development and production of machinery and molds will be valued. Plastic molding processing refers to the process of making final plastic products from polymers manufactured by synthetic resin manufacturers. Processing methods (commonly referred to as one-time plastic processing) include compression molding (compression molding), extrusion molding (extrusion molding), injection molding (injection molding), blow molding (hollow molding), calendering, etc. After the sheet is heated to a certain temperature by a blister machine, the plastic sheet is adsorbed on the surface of the model through a vacuum pump to generate negative pressure, and the plastic sheet is cooled and shaped to be transformed into a blister or blister of different shapes. Compression molding is also called compression molding or compression molding. Compression molding is mainly used for the molding of thermosetting plastics such as phenolic resin, urea-formaldehyde resin, and unsaturated polyester resin.
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.
