Embodiment 1
[0041]First, the building gypsum powder prepared from natural gypsum is used as a raw material, and the anti-radiation metal mesh made of alloy is selected. According to 100 parts by weight of natural building gypsum powder, 5 parts by weight of zeolite powder, 5 parts by weight of graphite particles, and 5 parts by weight of iron oxide powder, 5 parts by weight of calcium borate, 62 parts by weight of water, 3 parts by weight of reinforcing fiber, 2 parts by weight of reinforcing agent (selecting redispersible rubber powder), and measuring each component;
[0042] Secondly, the construction gypsum powder, zeolite powder, graphite particles, iron oxide powder, calcium borate powder, reinforcing fiber and reinforcing agent are fully mixed in advance;
[0043] Next, mix the weighed water and the evenly mixed powder in the mixer, pour it into the lower mold that has been sprayed with the release agent in advance, and pour the amount of slurry into about 1 / 3-1 / 2 of the total amount...
Embodiment 2
[0048] First, the building gypsum powder prepared by desulfurization gypsum through a fluidized calciner is used as a raw material, and a radiation-proof metal mesh made of iron is selected. 8 parts by weight of iron powder, 8 parts by weight of calcium borate, 65 parts by weight of water, 2 parts by weight of reinforcing fiber, 3 parts by weight of reinforcing agent (select polyvinyl alcohol), measure each component;
[0049] Secondly, the construction gypsum powder, zeolite powder, graphite particles, iron oxide powder, calcium borate powder, reinforcing fiber and reinforcing agent are fully mixed in advance;
[0050] Next, stir the weighed water and the uniformly mixed powder in a mixer, pour it into the lower mold that has been sprayed with a release agent in advance, and pour the slurry into about 1 / 3-1 / 2 of the total amount, Put in the anti-radiation metal mesh and fix its position;
[0051] Thereafter, pour the rest of the formed gypsum mixed slurry again, cover the up...
