rubber mixer is a common rubber mixing equipment in rubber product manufacturers. It is mainly used for raw rubber mixing, so that raw rubber and various compounding agents are fully mixed and uniformly dispersed. The following is a brief description of the common knowledge of rubber mixer mixing. In the production process of rubber products, the plasticizing and mixing of raw rubber is an important process. Usually, a rubber mixer or an open mixer is used for mixing. The following is a detailed description of the reasons why raw rubber needs to be masticated.
The follow is the list
What is a rubber rubber mixer made of?
Preparatory work required for rubber mixing
The feeding sequence of rubber mixer
The rubber rubber mixer is composed of a mixing chamber and two rotors, an upper top bolt, a lower top bolt, a temperature control system, a heating and cooling system, a discharge device, etc. The rotor is a spiral ridge, and the ridge can be divided into two parts. , four, six edges and so on. The cross-sectional geometry of the rotor of the rubber mixer can be divided into triangle, circle or ellipse, etc. The common rotors are shear type and kneader type. The rubber mixing process of the rubber mixer is to generate shear force through the relative rotary motion of the rotor. Under the conditions of high temperature and high pressure, the molecular chain of the raw rubber is broken and the compounding agent is fully mixed and dispersed.
When the rubber mixer is mixing rubber, it is necessary to calculate the amount and formula of one-time mixing according to the capacity and filling coefficient in the mixing chamber, prepare the raw rubber and various compounding agents according to the raw materials in the formula, and then turn on the rubber mixing machine. The power supply and heating switch preheat the rubber mixer. At the same time, it is necessary to check whether the voltage and water pressure of the rubber mixer meet the process requirements and whether the systems are normal. After the preheating is completed, the rubber can be ready to be mixed and the rubber can be lifted. Put the raw rubber and compounding agent into the rubber mixing machine according to the order of the top bolt on the mixer to carry out rubber mixing.
Attention should be paid to the feeding sequence of rubber mixer. Usually, raw rubber is added first and then carbon black. After the carbon black and raw rubber are fully dispersed, a liquid softener is added to improve the mixing effect and shorten the mixing time. Adding too early or too late will affect the mixing, resulting in uneven dispersion and prolonged mixing time. Sulfur and superspeed accelerator are generally added later after mixing, usually on the open mill to avoid scorch. Solid softener, activator, accelerator, anti-aging agent and anti-scorch agent are mixed before adding carbon black.
