Silicone adhesivesThe sizing method has the glue gun manual hand push, semi-automatic dispensing machine glue, automatic dispensing machine glue, etc., no matter what the glue method, if the application process is not glued now, what is the reason?
one, needles
When many users use silicone adhesive, due to the structure of the product itself, they will choose to use a small needle for sizing, and the key to the needle is the choice of inner diameter, if the product gap is very small, you need to choose a needle with a smaller inner diameter, then the viscosity of the selected silicone adhesive should also be small.
2. Air pressure
As we all know, the lower the temperature, the fluidity of the adhesive product will be relatively worse, to ensure that the amount of glue and the rate of glue meet the same requirements, then the air pressure should be relatively increased, especially the use of needle sizing, and is a user with a small inner diameter of the needle, in the environment where the temperature becomes low, the increase in air pressure is one of the ways to prevent gluing without gluing.
3. Viscosity. In the case that the inner diameter of the needle and the air pressure of the glue can not be changed, it is a problem in terms of selection, the key is viscosity, so the user is using the needle glue process, it is necessary to fully understand the inner diameter of the needle, as well as the range of air pressure can be adjusted, choose the adhesive that matches the viscosity, and can not simply use dilute to correspond, for the needle gluing process, the viscosity recommendation must be quantified, because the smaller the inner diameter of the needle, the stricter the fluctuation range of viscosity, a little hundreds may not be glued.
All in all, when the silicone adhesive is applied, the equipment cannot be glued, and the matching of some parameters is not evaluated in place, of course, there are other factors, such as curing, storage, etc., welcome to pay attention to Schnees for more related information.
