Hydraulic silicone rubberHydraulic silicone rubber O-ring PRECAUTIONS parked ripening time

 

Hydraulic kneading silicone O-ring in accordance with the requirements of the specimen thickness showings must be cooked into after showings, hydraulic rubber O-rings deposited in the warehouse, on a flat, clean, dry metal plate is cooled to room temperature (efficient management methods Make rubber is deposited on the trolley to move freely), and then at 23 +/- 2 ? condition, parking 22-24 hours, and to prevent moisture absorption. Silicone back when needed refining, refining shall return roller pitch, roll back requirements mild refining time will be.

 

Make silicone fatigue, mechanical stress suffered slack kneading; reduce silica gel contraction; so complexing agent continues to spread in the parking process, in order to promote uniform dispersion; so that between the rubber and the carbon black further generate binding silica to improve the reinforcement effect .

 

After mixing silicone rubber silicone to prevent sticking on the surface spread talcum powder, talc, or silica gel is immersed in the dispersion of cooling water tank, pulled back, dried silica, talc adhesion surface to prevent sticking silicone phase. The company's hydraulic O-ring is to make silicone releasing agent by an aqueous solution, after cold feeder (blowing fan) cooling. After the film (or granulated) plastic material, which is still up showings temperature 80-90 ?. Silica gel is a poor conductor of heat, stored at such temperatures, leading to scorch, it must go through the forced cooling.

 

 

When storing mix should be properly managed, it may have quality problems, such as mild scorch like. Silica during storage, the temperature must be controlled and shorten storage time, to avoid scorching. Send and receive silicone, should register recorded, according to the order of use. Prone to scorch or stock performance unstable compound should be treated differently, not only to be stored separately, often overturned, so that timely dissemination of internal heat, but also to use as soon as possible. Easy to scorch the rubber flip once every 2-3 days, the general rubber flip once every 6-7 days. The returned plastic materials, particularly scrap, to be kept separate, not with the original film intermixing. On schedule, should be accurate, to reduce the backlog and shorten the cycle time.

 

High summer temperatures, with particular attention to the management of silica gel. Common cool storage methods are: with a release agent, cooling water refrigeration cycle; the establishment of underground air-conditioned library or gum rubber compound library storage; water curtain can also glue library, the library walls with a plastic water pipe, water is sprayed onto the sacks to cool down. In short, the storage should pay attention to the following points:

 

(1) library ventilated rubber, silicone protected from direct sunlight, the indoor temperature should lower some attention summer cooling; (2) should not be stacked too high silica, and regularly flip, in order to facilitate dissemination of internal heat; (3) silica gel parking ripening after the storage time should not be too long.
