Embodiment 1
[0027] 1. Weaving the net
[0028] Select a single cotton filament with a diameter of 80-90 μm and weave it into a square grid with a side length of 2.5 mm on a net weaving machine. % polyvinyl alcohol 217 aqueous solution, dried at room temperature, and cut from the mesh frame to obtain a cotton mesh.
[0029] The above-mentioned polyvinyl alcohol 217 is provided by Tianjin Huachangyuan Chemical Trading Co., Ltd., its viscosity is 20.5-24.5cps, and the alcoholysis degree is 87%-89%.
[0030] 2. Deacidification
[0031] The basic magnesium carbonate and distilled water were mixed in a mass ratio of 1:130, and then carbon dioxide gas was continuously introduced into the mixed solution, and after 48 hours of reaction at room temperature, the upper layer clear liquid was obtained to obtain an aqueous magnesium bicarbonate solution. in as figure 1 Lay a layer of varnished cloth on the arched booth shown, lay the fragile paper to be reinforced on the varnished cloth, and then us...
Embodiment 2
[0037] 1. Weaving the net
[0038] Select a single cotton filament with a diameter of 80-90 μm and weave it into a square grid with a side length of 1.5 mm on a net loom, and spray a mass fraction of 8% on the grid with a spray gun under the condition of a spray pressure of 4 atmospheres. The polyvinyl alcohol 217 aqueous solution was dried at room temperature and cut from the mesh frame to obtain a cotton mesh.
[0039] 2. Deacidification
[0040] The basic magnesium carbonate and distilled water were mixed in a mass ratio of 1:80, and then carbon dioxide gas was continuously fed into the mixed solution, and after 48 hours of reaction at room temperature, the upper layer clear liquid was obtained to obtain an aqueous magnesium bicarbonate solution. in as figure 1 Lay a layer of varnished cloth on the arched booth shown, lay the fragile paper to be reinforced on the varnished cloth, and then use a small warehouse-type sprayer to spray the newly prepared magnesium bicarbonate...
Embodiment 3
[0046] 1. Weaving the net
[0047] Select a single cotton filament with a diameter of 80-90 μm and weave it into a square grid with a side length of 3.5 mm on a net loom, and spray a mass fraction of 3% on the grid with a spray gun under the condition of a spray pressure of 6 atmospheres. The polyvinyl alcohol 217 aqueous solution was dried at room temperature and cut from the mesh frame to obtain a cotton mesh.
[0048] 2. Deacidification
[0049] The basic magnesium carbonate and distilled water were mixed at a mass ratio of 1:150, and then carbon dioxide gas was continuously introduced into the mixed solution, and after 48 hours of reaction at room temperature, the upper layer clear liquid was obtained to obtain an aqueous magnesium bicarbonate solution. in as figure 1 Lay a layer of varnished cloth on the arched booth shown, lay the fragile paper to be reinforced on the varnished cloth, and then use a small warehouse-type sprayer to spray the newly prepared magnesium bic...
