How does the internal mixer work
When the internal mixer is working, the two rotors rotate relative to each other, and the material from the feeding port is clamped and brought into the roll gap to be squeezed and sheared by the rotors. After passing through the roll gap and touching the sharp edge of the lower top bolt, it is divided into two parts, Return to the top of the roll gap along the gap between the front and rear chamber walls and the rotor. During the cycle of flowing around the rotor, the material is subjected to shearing and friction everywhere, so that the temperature of the rubber material rises sharply, the viscosity decreases, and the wettability of the rubber on the surface of the compounding agent is increased, so that the rubber and the surface of the compounding agent are in full contact. Compounding agent agglomerates go through the gap between the rotor and the rotor, the gap between the rotor and the upper and lower top bolts, and the inner wall of the mixing chamber together with the rubber, and are broken by shearing, surrounded by stretched and deformed rubber, and stabilized in a broken state. at the same time,
In clean area management and quality control, laminar flow interference testing has received much attention, and whether it is only applicable to Class A laminar flow remains to be considered.
