How to increase the vulcanization speed of silicone waterproof ring?



When the silicone waterproof ring is vulcanized, it will cause polymer reaction to generate low molecular compounds, which can improve its mechanical properties, but sometimes the speed is very slow, which affects its basic progress. For this we need to adopt some methods to Increase its speed, which can improve production efficiency.



Silicone waterproof ring manufacturers introduced that in order to increase the vulcanization speed of the silicone waterproof ring, the amount of vulcanizing agent added to the silicone material can be appropriately increased, or a fast vulcanizing agent can be selected to speed up the vulcanization speed of silicone products and shorten the molding time. The vulcanization temperature during molding can be appropriately increased, but the structure of general products will be different, so the specific temperature needs to be determined by experiment.










Change the discharging method of the material of the silicone waterproof ring, try to make the silicone material can fill the entire inner wall of the mold as much as possible when the mold is pressurized. The molding operator speeds up the operation and minimizes the time outside the mold, so as to stabilize the temperature of the silicone product mold and increase the vulcanization speed of the silicone product.



Change the exhaust times and exhaust stroke of the silicone waterproof ring. According to common sense, the larger the exhaust stroke, the more exhaust times, which will be beneficial to exhaust. However, this is not the case. We need to decide according to the structure of the product. Some silicone products have a large exhaust stroke, but problems such as bubbles will occur.



Silicone waterproof ring manufacturers introduced the molding operators to speed up the operation speed and minimize the time outside the mold, so as to stabilize the temperature of the silicone product mold and increase the vulcanization speed of the silicone product. It is produced by a vacuum vulcanizing machine. If there is no vacuum vulcanizing agent, ^ Fortunately, use a steel pipe prying mold to assist in the exhaust.



The above introduction is how to improve the vulcanization speed of the silicone waterproof ring. I hope it can be helpful to you. If there is anything you don’t know, you can directly communicate with our customer service. We will serve you wholeheartedly, thank you for your Watch.
