[0077] Test Case

[0078] 1. Test subjects

[0079] The environmentally friendly pottery colored stones prepared in Examples 1-3 are the common pottery colored stones on the market.

[0080] 2. Test content

[0081] (1) Formaldehyde concentration

[0082] According to the national standard QB T27612006 "Measurement Method for Purification Effect of Indoor Air Purification Products", an experimental device was built to conduct experimental tests. After 24 hours, the formaldehyde concentration (mg / m 3 The initial concentration of formaldehyde in each sample chamber is 0.001 mg / m 3 .

[0083] 3. Test results

[0084] Table 1 Test results of relevant properties of environmentally friendly ceramic colored stone

[0085]

[0086] For the environmentally friendly pottery colored stones prepared in Examples 1-3, the formaldehyde concentration increased over time (from 24 hours to 72 hours), but the increase was very small and remained at an extremely low level (far below the safety limit specified by the national standard). The formaldehyde concentration of common pottery colored stones on the market also tended to increase over time, but the increase was significantly greater than that of Examples 1-3, and the concentration value was significantly higher than that of the example products.

[0087] In summary, the environmentally friendly ceramic colored stones prepared in Examples 1-3 performed well in controlling formaldehyde concentration, which was much lower than the common ceramic colored stones on the market. This was due to the environmentally friendly raw materials (such as flax core mixture, environmentally friendly emulsion, etc.) and scientific preparation processes (such as the addition of microbial enzyme catalytic liquid, centrifugal separation of chemical flocculants, etc.) used in the preparation process. With the combined effect of these measures, the products of the examples achieved lower formaldehyde emissions and higher environmental performance while maintaining excellent performance.

[0088] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the technical solutions of the present invention can be modified or equivalently replaced, but these modifications or replacements are all within the protection scope of the present invention.
