Biochemical characteristics of Aspergillus Niger and its relationship with human diseases, how to remove mold on the wall

Mix copper sulfate and lead-potassium alum (available in chemical building shops) at the ratio of 2: 1, put the ingredient of 1 into a glass or bottle container, add 10 part of water, heat to 40℃, add 7 parts of hydrated lime into the solvent to make porridge, and evenly coat a thin layer on the wall. About 500 grams of material per square meter.

In addition, I'll introduce you to a moistureproof trick:

Intermittent ventilation: afternoon is the best time. Close the doors and windows facing south or southeast in rainy days to reduce water vapor entering the room. At noon, the outdoor air humidity is at the highest value, so it is not suitable to open the window. In the afternoon or evening, when the climate is dry, open the window to adjust the indoor air.

Lime absorbs moisture: In rainy days, you can wrap quicklime with cloth or sack and put it indoors to keep the indoor air dry.

Air conditioning dehumidification: simpler than the first two methods, but power consumption. It is suggested to use other environmental protection and moisture-proof methods to save energy.

You can also put some practical moisture-proof small objects in the room:

Moisture absorption box: necessary for wardrobe dehumidification. Generally, the common absorbent products on the market are mainly composed of calcium chloride particles, and most of them are added with essence, so they have the functions of dehumidification, fragrance, mildew prevention and deodorization. Moisture absorption boxes are mostly used for moisture absorption in wardrobes and shoe cabinets. When you use it, just put it in the cupboard.

Absorbent bag: the best effect is confined space. The principle of water-absorbing bag is similar to that of water-absorbing box, but the contents are mainly water-absorbing resin, which becomes jelly-like after absorbing water and cannot be easily broken into pieces. It has a wider range of applications. Besides clothes, leather goods, stamps, cameras, pianos, computers, audio-visual equipment, etc. Can seek its help in dehumidification. If placed in a closed space, the moisture absorption effect is better.
