Background
The reason why the ceiling mildews is a common phenomenon in wet areas in the south is that the common building materials have capillary holes, underground water can permeate upwards along the capillary holes of the wall body, moisture slowly separates out from the surface of the wall body to cause mildewing, the moisture below the overhead plate can permeate into the capillary holes in the floor slab, and the moisture slowly separates out from the surface of the floor slab to cause mildewing and stain on the ceiling. In addition, the floor tile is affected with damp and is one of the mildewed factors of the ceiling, in plum rain seasons, the humidity water vapor content of air is high, the temperature is also high, a cold bridge exists between the floor tile and the original ground, the bridge breaking treatment is not performed during decoration paving, low-temperature underground airflow and moisture are continuously conducted to the ground, the temperature of the floor tile is always lower than that of the air, the water vapor in the air meets the cold ceramic tile, the ceramic tile does not absorb water basically, water drops are condensed on the surface, the ceramic tile is affected with damp, the ceiling below the floor is affected with damp, and besides, water leakage of a water pipe is also one of the mildewed reasons of the ceiling due to damp.
Since the ceiling is high and difficult to treat than the surrounding walls, it is more desirable to prevent the ceiling from becoming moldy. After the ceiling mildews, the putty paint partially falls off, the attractiveness is reduced, a large amount of spores are generated by the mildewed mildew on the ceiling and are scattered in the air, the surrounding air is full of musty smell, the spores can be diffused to other walls, other areas are mildewed, and the overall decoration is damaged. Mould is an atmospheric biological pollutant, which can cause anaphylactic reaction to people, invade human bodies and cause asthma, urticaria, allergic rhinitis, mycosis removal and the like, so that the mould and mildew spots are strictly prohibited on ceilings or walls in places with sanitary requirements, such as operating rooms, sickrooms, medicine storage rooms and the like of hospitals. Therefore, there is an urgent need for a mold preventive and mildew preventive that can effectively prevent the growth of mold on ceilings and effectively remove mold.

Example 3 compared with comparative example 2, the mould removing and preventing agent prepared in example 3 can kill the mycomyces on day 7, while the mould removing and preventing agent prepared in comparative example 2 can detect the mycomyces on day 13, which shows that the mould removing and preventing agent prepared in example 3 has better effect than the mould removing and preventing agent prepared in comparative example 2.
The ceilings of example 3 were replanted with M.pullulans, and it was found that example 3 could not be successfully inoculated with M.pullulans after the examination.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention as defined in the appended claims. The techniques, shapes, and configurations not described in detail in the present invention are all known techniques.
