The solution to silica gel thickening

Generally speaking, liquid silica gel is good for half a year. If it exceeds one year, the viscosity of silica gel will thicken with time. The expired liquid silica gel will solidify into a mass with almost no fluidity. We are very difficult. The fluidity of expired liquid silicone will be very poor and almost agglomerate, which will cause the AB glue to be difficult to stir and the phenomenon of non-leveling when filling the glue. If a large amount of silicone oil is added, the tear resistance and toughness of the silicone will decrease after curing. How to increase the fluidity of liquid silica gel without affecting the performance of silica gel?

There is something called an expansion bolt on the market. You can buy a suitable length according to the amount of silicone, as shown in the figure below. After buying it back, we use pliers to break the front opening of the jacket of the expansion bolt into a cross shape, then tighten the nut, tighten it, and a simple mixing head is ready. Next, the stirring head was stuck on the electric drill and started to stir frantically, and the stirred silica gel resumed its fluidity again. The liquid silica gel that has just been stirred will become a little hot due to friction and molecular movement, and there are many bubbles. It is unwise to use it immediately. First, it will foam easily, and second, because the heat itself will speed up the reaction, it is still easy to foam.  Let's let it go for a while, let it cool before use.
