Silicone manufacturers in the process of production of silicone products, there are a lot of common problem, today it is found mainly talk about product streaks, wiring problem how to solve, the following is composed of silica gel products factory take you know about the problem about the dark grain. The cause of silica gel products problems: 1. Mixing time is too short, lead to the inside of the original uneven colors in our rubber mixing process in the first place, due to mechanization rubber mixing, mixing is not uniform, can appear more or less when add the vulcanizing and masterbatch, the mixing time is too short, lead to the inside of the original uneven color, color half deep shallow, so for rubber mixing researchers need to important, the first working procedure is the most important. 2. Placed too long lead to make silicone products appear bad product in place after the completion of the mixing time too long can lead to make silicone products appear bad product, generally placed too long the hardness of raw materials to products have very big change, should be in a timely manner to use, don't put too long, one or two days at most. 3. Enough temperature can make the silicone products after streaks in the forming process of the raw material, just practice forming mold, to the outside temperature debugging, such as inadequate temperature leads to the silicone products come out after the stripe, even not familiar phenomenon, so every time you start to make the temperature to rise. When sulfide too high will also appear problem, silicone raw materials itself as the transparent color, in the add color made by high temperature vulcanization, no problem under normal temperature, curing time is too long, however, as the temperature rise will cause pigment has a slight dispersion phenomenon in the raw materials, so products will appear in color deviation, appear dark mark, it's not sexual in production when the temperature is too high, the temperature is too low to no, keep moderate, such products can be resolved the dark mark. After the above narrative, know about silica gel dark grain problem is there? In the process of production, pay attention to the problems above, can reduce or even avoid the silicone dark grain production, quality and production efficiency of silica gel can be greatly improved. Shajing silicone manufacturer produces silicone 15 years, has rich experience in production and production skills, silica gel products factory integrity, strength and product quality obtain industry acceptance. Welcome friends from all walks of life come to visit, guidance and business negotiation.
