Sintering of PTFE products is an important link in the forming process of PTFE products. It will cause fundamental changes in the properties of PTFE products.
Sintering temperature, cooling speed and other technological conditions directly affect the molecular weight, crystallinity and porosity of products. These three factors also affect the physical, mechanical and electrical properties of the products. At the same time, whether the sintering process is completed well or not affects the size and distribution of residual stress in the products. Therefore, improper sintering process control will lead to warpage, deformation and even cracking of the products.
PTFE sintering furnace produced by our company has good temperature uniformity, high degree of automation and stable performance. It is an ideal special equipment for sintering PTFE products.
1. High temperature uniformity: the imported high-precision 6-way or 12-way temperature circuit detection recorder can be configured according to the user's needs. The actual working temperature of each point in the furnace can be displayed and recorded in the whole process.
2. High precision of temperature control: the main temperature control meter adopts intelligent program temperature controller, which can be programmed with multi-stage program, PID self-tuning, SSR solid state electric appliance + cycle controller to adjust power, and automatically complete the whole process of sintering; The tunnel type sintering furnace can be divided into several temperature zones to control the temperature, so that the entire working chamber temperature is more uniform; When cooling down, the temperature can be lowered according to the process curve. The sintering furnace cooling fan, the air inlet automatically controls the opening angle of the air door, and the air outlet is equipped with a fully automatic exhaust valve. The whole furnace operation is controlled by PLC, and the sintering process is fully automatic.
3. Stable performance and reliable quality: the blower motor, impeller and electric heating device are all made of high temperature resistant materials, which can adapt to the continuous work 24 hours a day without stopping. The quality is stable and reliable, the noise is low, the furnace body do not shake while working.
4. Easy maintenance: fan, electric heater and other accessories all get standardizedand modularized according to different sintering furnace structure r to make fault judgment more accurate, and accessories maintenance more convenient, timely and low cost.
5. This equipment is a kind of intelligent sintering furnace with high uniformity and high reliability specially designed and manufactured for such materials as have extremely high requirements for furnace uniformity, for instance, PTFE. It is widely used in pre-sintering, sintering, finalizing and gluing of PTFE bars, plates, tubes and powders.
