1, mixed rubber in order to prevent rubber sticking, spread talcum powder on the surface, or the rubber immersed in talcum powder dispersion in the tank cooling, fishing, rubber dry, talcum powder adhesion surface, prevent rubber sticky. The glue is cooled by a cooling machine (blown by a fan) after passing through an aqueous solution of anti-stick agent. After the sheet (or granulated) of the rubber material, the temperature of the next sheet is still 80-90℃. Rubber is a poor conductor of heat, and when stored at such temperatures it causes scorch and must be forced to cool.

2, after cooling the rubber must be parked, in order to achieve the following purposes:

(1) make the rubber material recover fatigue, relax the mechanical stress suffered by mixing;

(2) reduce the shrinkage of rubber material;

(3), so that the coordination agent in the process of parking to continue to spread, to promote uniform dispersion;

(4) Make the rubber and carbon black further generate combined rubber, improve the reinforcing effect.

3, plastic material parking ripe storage items

(1), the lower mixing rubber, in accordance with requirements of the sample thickness, the lower the must ripening, deposited in the rubber warehouse, placed in a smooth, clean, dry on the metal plate of cooling to room temperature (high efficiency management method is tempered rubber accumulation is in the car, in order to move freely), and then under the condition of 23 + / - 2 ℃, 22-24 hours, and to prevent moisture absorption. When the rubber material needs to be returned to refining, it should be carried out according to the requirements of roller distance, roller temperature and time.

(2) The mixing glue should be properly managed when stored, otherwise there may be quality problems, such as mild burning.

During storage, temperature must be controlled and storage time must be shortened to avoid burning. The delivery and receipt of adhesive materials shall be recorded in the account book and used in sequence. The glue that is easy to burn or unstable stock performance should be treated differently. It should not only be stored separately and often overturned, so as to send out internal waste heat in time, but also to be used as soon as possible. For easy coking glue every 2-3 days to turn once, for general glue every 6-7 days to turn once. The returned plastic materials, especially the scraps, should be kept separately and not mixed with the original film. In the planning arrangement, should be accurate, reduce backlog, shorten the cycle time.

Summer temperature is higher, especially to pay attention to management. Commonly used cooling storage methods are: with isolation agent, cooling water refrigeration cycle; The establishment of underground glue storage or air conditioning glue storage; Water curtain glue can also be used, that is, the four walls of the glue library are provided with spray pipes, and the water is sprayed to the gunny bag pieces to cool down.

In summary, the following points should be noted when storing:

A. Keep the glue storehouse ventilated, and the glue material shall not be directly exposed to sunlight. The indoor temperature should be lower, and pay attention to the cooling in summer;

B, the pile of glue should not be too high, and regularly turn over, in order to diffuse internal heat;

C. The storage time should not be too long.
