The difference between vacuum kneader and ordinary kneading machine
At the end of the 20th century, silicone rubber was widely used as a new synthetic rubber material in the electronics and medical industries. Silicone rubber has excellent heat resistance, cold resistance, dielectric properties, ozone resistance and weather resistance. The outstanding performance of silicone rubber is It can be used for a long time at temperatures ranging from -60 ° C (or lower) to +250 ° C (or higher). Following the emergence of foreign countries such as Dow Corning, 3M, domestic such as Zhenjiang Hongda, Shanghai Huitian more well-known silicone rubber production enterprises, the market demand is booming, its main production equipment is vacuum kneading machine, in the production process Silicone rubber will produce bubbles and some organic solvents. At that time, Nanjing Enso Technology Co., Ltd., now Nanjing Zhongbing Enso Technology Co., Ltd. has applied the vacuum system to the kneading machine. At the beginning of the design, it also encountered many technical difficulties. The choice of vacuum pump, the sealing of the pipeline, the sealing of the body, the solid-liquid separation and heat exchange of the exhaust gas. After many practices, the Enso people will break through all the difficulties and form a relatively perfect kneading machine vacuum system. It has been used today; many manufacturers have followed the production simulations, but they have not fully equipped the vacuum system accessories according to the mechanical design requirements. Many of them are the ears of the scorpion. The high-demand cyclone separator is replaced by a simple waste gas tank. The heat exchange equipment such as the device is missing, which makes the working temperature of the pump body high and the degree of vacuum Drop, to shorten the service life of the vacuum pump, therefore the majority of the use of units in the purchase of a vacuum kneading machine when we must look at the configuration of the vacuum system manufacturer's instructions, or ask a professional to ensure the stable operation of the kneading machine.
