Silicone rubber O-ring PRECAUTIONS parked ripening time

 

1, kneading silicone rubber O-ring in accordance with the requirements of the specimen thickness showings must be cooked into after showings, stored in a rubber warehouse, placed on a flat, clean, dry metal plate is cooled to room temperature (efficient management approach is to Make rubber 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.

 

2, rubber O-ring when the bully refining to note that when the mix is ??stored 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.

 

Silicone rubber O-ring retention management, 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, when the rubber O-ring silicone material storage note the following:

 

(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.
