Embodiment 1
[0034] The specific steps of the mineral casting surface processing technology are as follows:
[0035] S1. Demoulding on the inner surface of the mold: Drive the high-pressure pump to suck the release agent, pressurize it to 30MPa, and then spray it on the inner surface of the mold for mineral casting casting, so that there is no compressed air in the sprayed release agent to avoid compressed air. Ingress of moisture and other impurities leads to unsatisfactory release effect, which makes the surface of the release agent uneven;
[0036] S2. Coating anti-corrosion coating: mix the raw materials of anti-corrosion coating in equal proportions according to the set amount and put them in the container. The raw materials of anti-corrosion coating include polyacrylate, curing agent, pebbles and river sand, and the anti-corrosion coating The raw materials are: 60kg of polyacrylate, 20kg of curing agent, 12kg of pebbles and 8kg of river sand according to the mass specific gravity, an...
Embodiment 2
[0042] S1. Demoulding on the inner surface of the mold: drive the high-pressure pump to suck the release agent, pressurize it to 15MPa, and then spray it on the inner surface of the mold for casting mineral castings. In this way, there is no compressed air in the sprayed release agent to avoid compressed air. Ingress of moisture and other impurities leads to unsatisfactory release effect, which makes the surface of the release agent uneven;
[0043] S2. Coating anti-corrosion coating: mix the raw materials of anti-corrosion coating in equal proportions according to the set amount and put them in the container. The raw materials of anti-corrosion coating include polyacrylate, curing agent, pebbles and river sand, and the anti-corrosion coating The raw materials are: 5.8kg of polyacrylate, 2.2kg of curing agent, 1.5kg of pebbles and 0.5kg of river sand according to the mass specific gravity, and then use the mechanical arm to paint the anti-corrosion coating evenly on the surface...
