Test example
Test example 1
The aldehyde-cleaning effect of the radiation-proof lead plate composite gypsum board and the aldehyde-cleaning gypsum board is compared and tested. The specific test conditions are shown in table 1. The structure of the comparative composite board is the same as that of the embodiment 1, and the boards are bonded by adopting a bonding mode of fully bonding gypsum.
TABLE 1 comparison of aldehyde-cleaning effectiveness
| Example 1 | Example 2 | Example 3 | Example 4 | Aldehyde-removing gypsum board | Comparative composite sheet | |
| Aldehyde-cleaning effect | 93.3％ | 93.1％ | 92.8％ | 92.5％ | 93.9％ | 80.4％ |
As can be seen from the comparative data, in the examples 1 to 4 of the invention, the boards are bonded by combining the point bonding of the bonding gypsum and the point bonding of the bonding material, and the aldehyde-removing effect is equivalent to that of the aldehyde-removing gypsum board; and compared with the composite board, the formaldehyde-purifying effect is obviously greatly reduced.
Test example 2

| 1 | 2 | 3 | 4 | 5 | 6 | |
| Building gypsum | 100 | 100 | 100 | 100 | 100 | 100 |
| Rubber powder | 0.4 | 0.8 | 1.2 | 1.6 | 2.0 | 2.4 |
| Retarder | 0.15 | 0.15 | 0.15 | 0.15 | 0.15 | 0.15 |
| Heavy calcium powder | 0.3 | 0.5 | 3 | 2 | 1.5 | 3.5 |
TABLE 3 comparison of the bond strengths of the Cement test blocks
As can be seen from the comparative data in the tables above, the bonding strength of the bonding gypsum using the composition of the present invention is significantly superior to that of the commercially available bonding gypsum for the lead board and the paper-faced gypsum board.
