Polished Silicon Nitride Ceramic Plunger Bars Rods
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic Plunger:
The powerful data processing function of the Silicon Nitride central processing unit has effectively improved the work efficiency of the computer. During the data processing operation, it is not just a simple operation. The operation of the central processing unit is based on the instruction tasks issued by the computer user.
On the basis, in the process of executing the instruction task, the control instruction input by the user is realized corresponding to the CPU. With the rapid development of information technology in our country, computers are widely used in people's life, work and office automation. As a main control device, it plays a role in promoting the development of e-commerce networks and upgrades the CPU control performance.
The process has been greatly improved. Instruction control, actual control, operation control, etc. are the performance of the application of computer CPU technology. Select Control. The operation of the centralized processing mode is implemented on the basis of specific program instructions, so as to meet the needs of computer users. The important role played by command and control technology.
According to the user's needs, the operation mode is formulated, so that the orderly formulation of data command actions can be well maintained.
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.
