Embodiment 1
[0056] (1) Due to the long overall size, this design needs to be poured twice;
[0057] (2) Raw material preparation: first weigh 15.0 g of silica gel A reagent with an electronic balance;
[0058] (3) Reagent mixing: After clearing the balance, continue to add 15.0 g of B reagent, and the whole operation process is about 3 minutes;
[0059] (4) Stirring vulcanization: the operating room temperature is 24°C, the stirring speed is about 70rmp, and the stirring time is controlled for 90s to fully mix the materials;
[0060] (5) Remove air bubbles: pour the raw materials prepared in step (3) into a centrifuge tube, and remove air bubbles by centrifuging for 1 min with a centrifuge speed of 3000rmp;
[0061] (6) Mold treatment: apply a layer of glycerin evenly in the mold with a brush;
[0062] (7) Injection molding: Slowly inject the mixed raw materials without bubbles after centrifugation in step (4) into the inner cavity of the first molding mold 3 ( figure 1 ) to fill the e...
Embodiment 2
[0069] (1) Raw material preparation: It is estimated that the finished product needs about 28g of silica gel. Considering the possible waste in the material configuration process, the best ratio of silica gel curing is 1:1, so pour the silica gel A reagent into the beaker during the material ratio stage 15.0g;
[0070] (2) Reagent mixing: After clearing the balance, continue to add 15.0 g of reagent B, and the whole operation process is about 3 minutes;
[0071] (3) Stirring vulcanization: operate at room temperature of 28°C, use a magnetic stirrer to stir at a speed of about 40rmp, and stir for 5 minutes to fully mix reagent A and reagent B;
[0072] (4) Remove air bubbles: pour the raw materials prepared in step (3) into a centrifuge tube, and remove air bubbles with a centrifuge for 2 minutes, and the centrifugal speed is 2500rmp;
[0073] (5) Mold treatment: use a brush on the inner side of the outer wall 13 of the mold ( Figure 4 ) apply a layer of glycerin evenly;
