[0033] Silicon dioxide resin curing agent can be produced in multiple ways, one of which is the sol-gel method, which includes the following steps:

[0034] Solution preparation: dissolve a silicon source (such as sodium silicate) in a solvent to form a uniform solution.

[0035] Gelation: control the temperature, pH value, and other conditions of the solution to gradually polymerize the silicon source in the solution to form a gel.

[0036] And the paint production process of the curing agent also mostly for emulsions (may also be solid, so after the gelatinization increases a procedure, aging and drying: the gelatinization is aging treatment, to enhance its structural stability, then through the drying process to remove the solvent in the gelatinization, get nanoscale silica particles.), and emulsions via feed tube 3 into the dosing cylinder 1, in order to avoid the blockage of feed tube 3, usually need to let feed tube 3 distance dosing cylinder 1 bottom exists certain spacing, emulsion falls, directly dropped to the bottom of dosing cylinder 1, between dosing cylinder 1 and the rapid collision, can cause emulsion splash, splash in the process will adsorb the air in dosing cylinder 1; And emulsion into dosing cylinder 1, in order to avoid its solidification, need to heat it, two kinds of situation superimposed, can cause emulsion mixed with more bubbles, and dosing cylinder 1 weighing, need to measure the volume of emulsion in dosing cylinder 1, the existence of bubbles can cause the volume measurement results and actual results exist deviation, lead to emulsion sampling quantity is not accurate, therefore the lower part of feed tube 3 is provided with guide plate 4;

[0037] Specifically, the guide plate 4 includes first inclined portion 401, second inclined portion 402, third inclined portion 403, the inclination angle of the first inclined portion 401 and the third inclined portion 403 is smaller, and the inclination angle of the second inclined portion 402 is larger, the first inclined portion 401, the second inclined portion 402 and the third inclined portion 403 are connected smoothly, the third inclined portion 403 faces the inner wall of the dosing cylinder 1, and there is a gap between the third inclined portion 403 and the inner wall of the dosing cylinder 1, the lower outlet 404 is arranged at the end of the third inclined portion 403, and the discharge pipe is arranged at the bottom of the dosing cylinder 1.

[0038] The lower part of the feed tube 3 is provided with the guide plate 4, and the emulsion enters the bottom of the dosing cylinder 1 along the guide plate 4, during the flow, the emulsion flows smoothly and does not collide with the inner wall of the dosing cylinder 1, reducing the bubbles generated by the collision.

[0039] The weight of the emulsion in the dosing cylinder 1 is detected by the weighing unit 9 at the bottom and the liquid volume measuring unit in the dosing cylinder 1, and the two groups of data are mutually reflected, so that the detected result is more accurate. Due to the heating, there are some bubbles in the dosing cylinder 1, so the lifting unit 8 is arranged on the cylinder cover 2, the output end of the lifting unit 8 is connected with the lifting plate, a plurality of bubble piercing needles 6 are arranged on the lower side of the lifting plate, the bubble piercing needles 6 are arranged on the pressing plate 5, and the outer circle of the side wall of the pressing plate 5 is attached to the inner wall of the dosing cylinder 1. The lifting unit 8 drives the lifting plate and the bubble piercing needles 6 to move up and down, which can pierce the bubbles generated by the heating of the emulsion and avoid the aggregation of the bubbles.

[0040] The guide plate 4 is positioned in the middle of the metering cylinder 1 to serve as a guide. To avoid collisions between the guide plate 4 and the bubble-piercing needle 6, the bubble-piercing needle 6 is positioned near the inner wall of the metering cylinder 1. Since bubbles mixed in with the emulsion in the vicinity of the guide plate 4 remain unpunctured, two sets of thrust components are installed on the lifting plate. Each set of thrust components has two thrust blades 7. The two thrust blades 7 push the emulsion in different directions, i.e., they push the emulsion from the middle to both ends, so that the bubble-piercing needle 6 can contact the emulsion at different positions at the same height and puncture the bubbles inside. The thrust blades 7 need to be connected to a power unit to drive their rotation.

[0041] Working principle:

[0042] A guide plate 4 is provided below the feed pipe 3. The emulsion enters the bottom of the metering cylinder 1 along the guide plate 4. During the flow, the emulsion flows smoothly and will not collide rapidly with the inner wall of the metering cylinder 1, reducing some of the air bubbles generated by the collision.

[0043] After the emulsion enters the metering cylinder 1, the weight of the emulsion inside the metering cylinder 1 is measured by the weighing unit 9 at the bottom and the liquid volume measuring unit inside the metering cylinder 1. The two sets of data are compared with each other, and the detection result is more accurate. The lifting unit 8 inside the metering cylinder 1 drives the lifting plate and the bubble-piercing needle 6 to move up and down, which can pierce the bubbles generated by the heating of the emulsion and prevent the bubbles from accumulating. The two thrust blades 7 push the emulsion in different directions, that is, push the emulsion from the middle to both ends, so that the bubble-piercing needle 6 can contact the emulsion at different positions at the same height and pierce the bubbles inside.
