heat dissipate aluminum oxide ceramic slide guide bar
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
Zinc oxide should also pay attention to the following points during use: before use, it must be calcined at a high temperature, the calcination temperature is about 1200 ℃, if it is added directly to the raw glaze without calcination, it will affect the process performance of the glaze. No calcination is required when adding frit. Too much zinc oxide in the glaze will affect the glaze gloss. Zinc oxide has a bad influence on some colored glazes, especially chrome glaze.
Zinc oxide can be used as a reinforcing agent, accelerator and vulcanizing agent in rubber products. In the rubber vulcanization process, it reacts with the organic accelerator stearin to produce zinc stearate, thereby enhancing the physical properties of the rubber during vulcanization and shortening the vulcanization time.
Zinc oxide is an activator of a foaming agent, which can reduce the decomposition temperature of the foaming agent and at the same time can adjust the consistency with the processing temperature of the rubber. Usually the amount is between 0.2-2phr, generally speaking according to the rubber system and foaming The dosage is different depending on the agent system.
1. The lifting and lowering of the work piece is driven by a variable frequency speed-regulating motor. The lifting screw adopts precision ball screw, which has stable transmission, high control precision, wide speed adjustment range, and intuitive and convenient adjustment. With brake braking, power failure electric braking function.
2. The rotation of the work piece is driven by a frequency conversion motor. The speed adjustment range is large, and the adjustment is intuitive and convenient; and the drive motor is located above the quenching position, which can effectively prevent the motor from being damp.
3. The electrical control is realized by intelligent PLC programming. The control system adopts two-stage isolation for input and output. It has strong anti-interference ability and good stability. It can be changed at any time according to the requirements of the customer's workpiece Yudong spray equipment.
4. The equipment has shaft, disc, disc, single-stage, multi-stage, intermittent, continuous quenching functions. A total of 6 sets of automatic control programs.
5. All movements are mechanical, which saves space and reduces equipment requirements. The machine tool is simpler, smaller in size, more convenient for operation and maintenance, and has a lower failure rate.
6. The lifting and rotating speed can be digitally and intuitively adjusted on the control panel, which can meet the high-precision adjustment requirements; and the speed can be adjusted steplessly according to the size of the workpiece and the requirements of the quenching process, so as to achieve better quenching effect and achieve workpiece quality 'S better.
7. The lifting limit position of the machine tool is controlled by the photoelectric switch. The machine tool is equipped with a failure buffer mechanism, but the machine tool may still have rigid damage after improper operation or failure of the switch for a long time.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
