Method of leakage treatment of secret refiners

The mixer is a closed rubber mixer, which is used for mixing rubber and plastic products, so that rubber and plastic and various compounding agents are fully mixed and dispersed evenly, and mixers are common equipment in rubber product manufacturers.

The mixer will inevitably fail after long-term use, such as water leakage, so how to deal with the leakage of the mixer?

If there is a water leak in the mixer, check whether there is any abnormality or sealing problem in the position of the rotor, mixing chamber, discharge door, pressure hammer, pipeline, etc., and solve it according to the actual situation. Water leakage in the mixer is relatively rare, the leakage is due to the reason of carbon black, because carbon black will absorb moisture in the air, when the mixing temperature of the mixer rises will produce a large amount of water vapor, the accumulated water vapor during the rubber discharge will produce the mixer "leakage" phenomenon, you can lift the pressurized cover several times during the mixing process of the mixer to discharge the water vapor, which will avoid the appearance of water vapor.

What are the good ways when the refiner is mixed with glue?

Mixing with a mill is an early mixing method in the rubber industry. Compared with mixing with a mixer, the mixing of the open mill has high labor intensity, poor production efficiency, unsafe, polluted environment, etc., and the uniformity of mixing is poor, so it has tended to be gradually eliminated. However, the use of open mill mixing, greater flexibility, mixed rubber is suitable for small production scale, small rubber batch and many varieties of factories. For the production of some special rubber materials, such as sponge glue, hard glue, color glue, etc., it is particularly suitable for mixing with an open mill, so the current use of open mill mixing in small rubber factories still accounts for a certain proportion.

The importance of the secret refining machine and the opening machine in plastic refining

Rubber is deformed by external forces, and the ability of rubber to maintain its deformation after the external force is eliminated is called plasticity. The process of increasing rubber plasticity is called plasticizing. Rubber has plasticity in order to be evenly mixed with various compounding agents during mixing; Easy to penetrate into the textile during calendering; It has good fluidity when pressing out and injecting. In addition, plastic refining can also make the properties of the rubber uniform, which is convenient to control the production process. However, excessive plastic refining will reduce the strength, elasticity, wear resistance and other properties of vulcanized rubber, so the plastic operation needs to be strictly controlled. Rubber plasticity is usually expressed in Williams' plasticity, Mooney viscosity, and Dever hardness.

How can the craft process of rubber products be missing?

There are many kinds of rubber products, but the production process is basically the same. The basic process of rubber products using general solid rubber (raw rubber) as raw material includes: plasticization, mixing, calendering, extrusion, molding and vulcanization 6 basic processes.

Knowledge of mixed refining machines

A section mixing method refers to the method of preparing mixed rubber after completing the addition of all compounds at one time, and is often used to prepare those rubber materials with good scorching performance and no or only a small amount of active compounds. In order to ensure that the temperature of the rubber in the mixing does not rise too fast, a period of low-speed mixing is generally carried out in the mixer.
