Performance testing
1. Formaldehyde purification effect test
The formaldehyde-removing enamel plates prepared in examples 1 to 5 and the common enamel plates prepared in comparative examples were respectively subjected to a formaldehyde purification effect test according to QB/T2761 to 2006, and the formaldehyde removal rates at 24 hours and 48 hours were measured and shown in Table 1.
TABLE 1 Formaldehyde purification Effect of different formaldehyde-removing materials
| Item | Content of formaldehyde-removing material/%) | 24h formaldehyde removal% | 48h formaldehyde removal% |
| Example 1 | 0.4 | 30.2 | 50.4 |
| Example 2 | 1 | 52.5 | 70.7 |
| Example 3 | 2 | 73.4 | 92.1 |
| Example 4 | 3 | 71.1 | 90.2 |
| Example 5 | 4 | 70.5 | 89.4 |
| Comparative example | 0 | 0 | 0 |
As can be seen from table 1, the enamel plate with formaldehyde removed prepared in the examples of the present invention has excellent formaldehyde removal effect compared to the common enamel plate, and the formaldehyde removal rate is the highest when the formaldehyde removal material content is 2%.
The decomposition principle of the formaldehyde-removing material is as follows:
based on Einstein stimulated emission theory, in atoms forming a substance, different numbers of particles (electrons) are distributed on different energy levels, and can jump from a high energy level to a low energy level when being excited by certain particle flow, and light waves, different materials and different excitations can be released in the process to generate light waves with different strengths.
Based on the characteristics, scientists have developed a special formaldehyde removing material which can absorb the energy of light, heat and the like from the surrounding environment and then emit a light wave, and the material is widely applied to aviation, removing various harmful gases such as formaldehyde, benzene and the like in aircrafts and purifying the air in cabins.
Scientists found that formaldehyde is extremely unstable, molecular chains are easy to break under the bombardment of light waves, and the formaldehyde reacts with oxygen to generate carbon dioxide and water, HCHO + O2＝CO2+H2And O, thereby achieving the purposes of purifying air and removing formaldehyde.
2. Comparative test of Performance
The mohs hardness of the enamel plates prepared in examples 1 to 5 and the ordinary enamel plates prepared in comparative examples were measured according to EN101-1991, the alkali resistance according to GB/T1855-1993, the acid resistance, impact resistance, temperature shock resistance, abrasion resistance and adhesion according to GB/T1855-1993, and the formaldehyde removal rate according to QB/T2761-2006, respectively. The test results are shown in table 2.
