What do you need to pay attention to in the winter and summer in the production of silicone tube?
The biggest difference between winter and summer is temperature, but in the production of silicone tube is a very important process when mixing. While the temperature of rubber has the effect. So in the winter and summer production of silicone hose should pay attention to the following.
First of all, silicone tube production, the general formula of winter curing agent and oil (softener) to add some appropriate. Because unfamiliar good curing and high hardness, northern winter general formulation plasticizing agent than in summer to increase 5, winter glue baking temperature and time will be extended. In winter and summer is mainly environmental temperature change, organic ten degrees of difference, affect the curing rate, at the same time, the operation is also influential. In the winter, the hardness of the vulcanized rubber was obviously improved, the coke burning time increased obviously. Generally the starting point in the winter to adjust slightly faster, more plastic agent, a little more, the summer is just the opposite of the road.
Secondly, silicone tube production, winter and next season on the formulation of the system is different from the south, especially in the south, especially O-ring, vulcanization rate of rapid production capacity, the difference between winter and the next season, the next season will be the formulation of the curing system down, coke burning time to mention a long, if it can be put in the winter! If the rate of curing in the summer or by the winter, then the production will appear in the large quantities of plastic coke burning, while the winter is good! If the sulfur content in summer is appropriate, the amount of accelerator can be increased in winter, and the storage period of the compound is shortened obviously, but the time of the anti - coke is prolonged.
In short, the silica gel tube production mix, or appropriate to extend the mixing time, or increase the temperature of the cooling water, the difference between winter and summer is that the temperature of the environment changes. Some difference in 30-40 degrees.
