Reclaimed rubber production can be said that a very complex process, selection, crushing, desulfurization, molding and so on. In summary, the production of reclaimed rubber has three main processes, broken gel - desulfurization - the next film, this paper reclaimed rubber reclaimed rubber production as an example to introduce these three processes.
1, broken plastic
In the stacking process, remove the non-metallic impurities (stones, other impurities), after the water rinse the surface without sediment, once again remove the non-metallic impurities, broken in plastic broken in 20 Head powder, in the crushing process, after five magnetic separation, remove the metal powder in the powder, according to a certain weight after weight, according to the production date stacking heap, the storage of the powder at any time for weight checks, In order to ensure the accuracy of the measurement of the next process, according to the principle of the first to take advantage of the husband.
2, desulfurization
Reclaimed rubber desulfurization can be said to control the quality of reclaimed rubber products, "the power of life and death," so there are many points to note in the desulfurization process:
(1) Each softener to the factory after a rigorous testing, storage after testing qualified.
(2) According to the production formula, a variety of softeners according to the amount of formula accurate measurement, and there are some ingredients.
(3) The rubber powder is metered again according to the production formula, and the water is also metered and put in a bucket for use.
(4) According to the high-strength reclaimed rubber desulfurization process, start the stirring device of desulfurization tank, add 75% of the powder and water, then add the metered softening agent, then add the remaining 25% of the crumb rubber, seal the tank, add gas ,heating.
(5) according to the requirements of high-strength reclaimed rubber desulfurization process, exhaust temperature when the pressure reaches the emission requirements.
(6) open the next tank mouth material, the discharge of hot rubber with a conveyor belt to the cooler, the cooling to 60 degrees below, transported to the designated site cool material, to be vulcanized rubber parked for 12 hours after entering Under the process of rolling rubber.
3, under the film
Reclaimed rubber under the film process can also be referred to as reclaimed rubber molding process, no molding before the reclaimed rubber is desulphurized powder, after forming the block or sheet, so this process collectively referred to as the next film. Reclaimed rubber tire under the film over the number of times to determine the quality of reclaimed rubber appearance, so the appearance of regular reclaimed rubber are neat and tidy.
(1) Firstly, the desulfurized rubber powder which is parked for 12 hours is fully kneaded in a kneading machine, mixed uniformly, and then placed in a refiner too thin to achieve the appearance of fine reclaimed rubber. After the following, the sample is naturally weighed according to standard packaging , After cooling to room temperature in the bag for coding. The reclaimed rubber of finished products in each shift is placed separately. The statisticians check the quantity of pickings and the number of finished products and mark the production date and shift.
(2) Generally, the output of each shift is within the fixed range. If the number of the reclaimed rubber in the day shift is 200 and the number of the reclaimed rubber in the night shift is 300, it shows that the number of times the roller shift has failed to meet the requirements in the next few days, Of the reclaimed rubber there may be uneven thickness, rough surface, the appearance of uneven problems.
