Basic Knowledge Of Rubber Two-Roll Mixer

The rubber two-roll mixer is an indispensable mechanical equipment in the rubber processing process. It uses two rotating rollers to shear, rub, squeeze and mix rubber to achieve plasticity, deformation, strengthening and other processing effects. We support Mass Production Two Roll Mill . Let's introduce some basic knowledge of the rubber two-roll mixer. First of all, the composition of the rubber two-roll mixer mainly includes the frame, rollers, driving device, fine-tuning device, lubrication device, electric control system, etc. Among them, the rollers are the core components of the mixer, and they are usually made of steel, driven by a gear reduction device or a frequency converter connected to a motor. The driving device is responsible for rotating the rollers, and the fine-tuning device can adjust the gap between the rollers to meet the needs of different mixing processes. Secondly, the working principle of the rubber two-roll kneading machine is very simple, which is to use the extrusion, shearing and friction between the rollers to knead the rubber. The mixing process is divided into two stages: hot mixing and cold mixing. In the hot mixing stage, after the rubber is heated to a certain temperature, the rubber molecular chain undergoes physical and chemical reactions such as deformation, bending, and fracture through continuous shearing, extrusion, and friction of the rollers of the mixer, thereby realizing plastic deformation and processing.

How To Solve The Temperature Control Problem Of Internal Mixer?

The temperature accuracy of the internal mixer is directly related to the results of ingredient research and development. Generally, the heating methods used are electric mold heating and oil heating. The power used by the electric heating of the internal mixer and the processing method of the mold are different, and the results are different. The specific solutions are as follows: Internal mixer surround type electric heating Unlike the Dispersion Kneader, the power of a single heating wire of the internal mixer can reach 2.1KW. The temperature difference between the two ends of the effect is more than ten degrees, and more tens of degrees. The main reason is that the heating wire cannot be tightly fitted or is not in contact with the inner wall at all, forming a hollow dry smelting. Using this method, the main performance is that the heating wire will be deformed after dry burning for a period of time, difficult to replace, and uneven temperature. However, because the power of the heating wire is relatively large and the structure is relatively strong, it is not easy to be burned out. Internal mixer single-head rod electric heating tube The maximum diameter of a single heating wire single-ended rod is 19.8, and the normal power is 1.7KW. This method has a relatively uniform temperature and an accuracy of ±2°C. The disadvantage is that the heating speed is slow and the power is low. If the power is increased, the heating tube will be easily burned out, and the replacement time and frequency will be increased.

How To Make The Internal Mixer Disperse More Evenly

How to make the internal mixer disperse more evenly? Like Rubber Internal Mixer, in order to improve the performance of rubber products, improve the performance of rubber technology and reduce costs, various compounding agents must be added to raw rubber. Mixing is the process of uniformly mixing raw rubber and various compounding agents through mechanical action. If the refining is not good, there will be uneven dispersion of the compounding agent in the rubber material, too low or too high plasticity of the rubber material, scorching, blooming and other phenomena, which will make it difficult to carry out the follow-up process normally and lead to a decline in the performance of the finished product. Due to the high viscosity of raw rubber, in order to uniformly mix and disperse various compounding agents, it must be mixed with the help of strong mechanical action of the rubber mixer. Various compounding agents, due to their different surface properties, have different reactivity to rubber. Inconsistent. In addition to the regular ones, there is also the Plastic Granulator. According to surface characteristics, compounding agents can generally be divided into two categories: one is hydrophilic, such as carbonate, clay, zinc oxide, lithopone, etc.; the other is hydrophobic, such as various carbon blacks. The surface properties of the former are different from raw rubber, so it is not easy to be wetted by rubber; the surface properties of the latter are similar to raw rubber, and are easy to be wetted by rubber. In order to obtain a good mixing effect, the surface of the hydrophilic compounding agent must be chemically modified to improve their activity with rubber, and the use of surfactants can play this role. Surfactants are mostly organic compounds with asymmetric molecular structures. It often contains polar groups such as -OH, -NH2, -COOH, -NO2, -NO or -SH, has unsaturated residu

How To Solve The Temperature Control Problem Of Internal Mixer?

The accuracy of the mixer temperature is directly related to the results of the research and development of ingredients. The heating methods generally used are electric heating mold heating and oil heating. The power and mold processing methods used in the electromechanical heating of the internal mixer are different, and the results are different. The specific solutions are as follows: Internal mixer wrap-around electric heating The power of a single heating wire can reach 2.1KW. The temperature difference between the two ends of the effect is more than ten degrees, and more are dozens of degrees. The main reason is that the heating wire cannot be closely matched or is not in contact with the inner wall at all, forming a hollow dry burning. Using this method, the main manifestations are that the heating wire is deformed after being dried for a period of time, it is difficult to replace, and the temperature is uneven. However, because the power of the heating wire is relatively large and the structure is relatively strong, it is not easy to be burned out. Internal mixer single-head rod electric heating tube The maximum diameter of a single heating wire single-head rod is 19.8 and the power is normally 1.7KW. In this way, the temperature is relatively uniform, and the accuracy can be ±2°C. The disadvantage is that the heating speed is slow and the power is small.

How To Choose A Motor For An Internal mixer?

In the process of selling internal mixers, many customers and friends have a lot of confusion in the purchase of AC motors and DC motors when purchasing internal mixers, open mixers and other rubber mixing equipment, according to the sales department. Sort out: 1. Explanation of terms DC motor: is to use direct current as a power source AC motor: It uses alternating current as a power source. 2. Structural Analysis The principle of the DC motor of the internal mixer/open mixer is relatively simple, but the structure is complex and inconvenient to maintain. The AC motor has a complex principle but a relatively simple structure, and is easier to maintain than a DC motor. 3. Working principle Internal mixer/open mixer DC motor is to introduce current into the rotor armature through brushes and commutators, so that the rotor is forced to rotate in the stator magnetic field. The AC motor (take the commonly used AC asynchronous motor as an example) is to pass the AC current into the stator winding, thereby generating a rotating magnetic field in the air gap of the stator and the rotor, and the rotating magnetic field generates an induced current in the rotor winding, so that the rotor is subjected to the stator magnetic field. Force produces rotation. The speed regulation of the DC motor is simple, but the application is limited. AC motor speed regulation is relatively complex, but it is widely used due to the use of AC power. The AC speed regulation is to change the speed of the motor by changing the frequency of the AC power supply,
