Silicone rubber should pay attention to what details?

Although rubber refining is the pre-production process of silicone products, but whether the mixing process is carried out in accordance with the operation process is directly related to the quality of the product, if it is not carried out in accordance with the regulations, then it is possible to produce products with impurities or unstable products, if it is rubber refining jerry-cutting, then the molded silicone products will also have a lot of problems, For example, the product is not uniform, more impurities, serious shortage of materials and so on.

Some silicone products manufacturers will not take into account the previous process will affect the following process, in fact, each process has inextricably linked, just say that the impact of the post-process on the previous process is limited, and the control of the previous process is a manufacturer must pay attention to the problem, especially the production of silicone products.

1. In the production of mixed silica gel, the first thing to pay attention to is factory hygiene and machine cleaning, such as production in a dirty environment, mixed silica gel is very likely to be mixed with impurities, resulting in mixed silica gel pollution;

2. Mixed silica gel must be mixed evenly in the kneading machine before it can be used, the time can not be too short or too long, the mixing uneven phenomenon will occur if the time is too short, the glue will be hot for too long, and it is easy to burn the hand during the cutting process. The correct approach should be to see when the rubber compound is mixed into a group or the color has been mixed evenly;

3. What is the bubble on the mixed silicone? Mixed silica gel in the open mixer mixer is not uniform, the general surface of mixed silica gel is clean and shiny;

4. Mixing silica gel rolling paper (also known as film paper) precautions, generally mixing silica gel after sulfur and color packaging, in mixing silica gel rolling paper must pay attention to the oil paper do not be opened into the rubber, once the oil paper involved in the rubber, if not stopped in time, then the batch of mixed silica gel completely scrapped;

5, mixing silica gel sulfur precautions, must be added in accordance with the dosage ratio, ordinary double 25 vulcanization agent can be added in the kneading machine or the opening mixer, adding in the opening mixer must pay attention to step by step, add amount by amount, adding too much at one time will lead to the loss of vulcanization agent or direct splash liquid, or even splash into the eyes of production personnel, the sulfur way is added in the kneading machine;

6, odorless vulcanizing agent adding precautions, odorless vulcanizing agent can not be added directly in the kneading machine, adding odorless vulcanizing agent in the kneading machine is prone to fire and even explosion accidents. The way is to mix silica gel in the open mixer process, slowly and gradually add odorless vulcanizing agent, remember that the less the better, can not be excessive!

7. Be sure to pay attention to the hand when cutting, the probability of the hand being cut in the cutting process is very high.
