What are the principles of open mixer plastication
Open mill plastication is generally affected by temperature, plastication time, roller speed ratio, roller distance, and rubber loading. Open mill plastication belongs to low-temperature mechanical plastication. The plastication temperature is generally below 55°C. The lower the temperature, the lower the temperature. The better the plasticizing effect.
Daily maintenance of tablet press
(1) First of all, keep the equipment clean and check the moving parts to ensure the cleanliness of the equipment. There should be no decarburization and scratches on the moving parts, and the moving parts should be flexible.
The structure of the pre-pressing device of the tablet press
(1) Pressure: The pressure of the pre-compression device directly affects the compression capacity of the tablet press. If the tableting pressure is too small, the tablet cannot be pressed out, and if the tableting pressure is too high, the mold or the tableting equipment will be damaged.
Precautions for tablet presses
In the process of using the tablet press, in order to avoid its failure, the following items should be paid attention to
Operation process of internal mixer
Internal mixer is a multi-functional equipment, which is composed of electric motor, electrical control system, hydraulic system and sealing system. When the internal mixer is working, the temperature, pressure and speed can be controlled throughout the operation process.
Double Roll Mill Structure
The twin-roll mill is an important equipment that organically combines the processes of raw rubber and rubber mixing. The two-roll mill is used to convey raw rubber and rubber, and heat the raw rubber and rubber in a relatively unstable state, thereby increasing its vulcanization speed and promoting mixing. The main equipments are two-roll mill frame, two-roll mill transmission mechanism and two-roll mill heating system.
