Is diatom mud really useful? What are the advantages and disadvantages of diatom mud for wall decoration?

With the improvement of consumers' environmental awareness, diatomaceous earth, the main component of diatom mud, is a new type of environmentally friendly decoration material "derived from nature". In addition to latex paint and wallpaper, diatomaceous earth Mud has also become one of the most popular wall decoration materials among consumers. A few days ago, the editor introduced an article about whether to use latex paint or wallpaper for wall decoration. Today I will introduce to you what diatom mud is and what its advantages and disadvantages are.

1. What exactly is diatom mud

Diatom mud is a mixture of diatomaceous earth, mixed lime, gypsum and other materials. Its main component is diatomaceous earth. Diatomaceous earth is a biogenic siliceous sedimentary rock composed mainly of the remains of ancient diatoms. Suitable for interior wall decoration in villas, hotels, homes, apartments, hospitals, etc. Japan was the first country to use diatom mud in the field of decoration. After being introduced to China, through the research and development of scientific and technological personnel, the performance and texture of diatom mud have been greatly improved, and it has gradually been widely used in the home decoration industry.

Due to its strong water absorption and poor water resistance, diatomite is not currently used in many exterior walls. Diatomite is a non-renewable natural resource. In addition to being used in decoration materials, it also plays a role in plasma filtration, sterilization, beer filtration, aviation interior walls and other industries. The domestic diatom mud market varies. When purchasing diatom mud, please do not be fooled by false advertisements.

2. Is diatom mud suitable for indoor wall decoration? What are its advantages and disadvantages?

Advantages of diatom mud:

1. Adjust humidity and prevent mildew

The main component of diatom mud is diatomaceous earth, which is a porous material. Under microscope observation, the particle surface has countless tiny holes. Because of its porous structure, it can adsorb suspended macromolecules in the air. Diatom mud can absorb or release water vapor in the air as the indoor air temperature and humidity changes in different seasons and morning and evening, automatically adjusting the indoor air humidity to achieve a relative balance, which is conducive to controlling the formation of mold and achieving a certain anti-mold effect. Using diatom mud for indoor decoration in the humid south can reduce the humidity in the air, while in the dry north, spraying water on the wall can temporarily act as a humidifier.

2. Purify the air and remove formaldehyde

Because diatom mud products have a unique "molecular sieve" structure and a certain physical adsorption capacity, they can effectively absorb free formaldehyde and formaldehyde in the air. Harmful gases such as benzene, but the decomposition process after it absorbs harmful gases is very long, and as the temperature changes, harmful gases will be re-released at high temperatures. Diatom mud only adsorbs harmful substances such as formaldehyde, and it cannot completely remove formaldehyde.

3. Fire retardant, thermal insulation

Baidu Encyclopedia shows that diatomite has low thermal conductivity and is equivalent to air, so it has good thermal insulation properties and is ideal thermal insulation materials. When the temperature rises to 1300°C, diatom mud only appears in a molten state and does not burn.

4. Protect eyesight

Due to its porous nature, diatom mud will diffusely reflect light, making the indoor light become softer after reflection, which is beneficial to protecting eyesight. , relieve visual fatigue.

Disadvantages of diatom mud:

1. Single color, only white, gray, earthy and other light colors. The texture is relatively rough and lacks smoothness. Apply diatom mud on the wall. After the diatom mud is integrated with the original wall, it will produce a different visual effect and enrich the three-dimensional sense of the space.

2. Diatom mud is relatively light in texture, lacks gravity resistance, is easy to wear, and is not resistant to dirt.

3. It is not waterproof and cannot be scrubbed. Diatom mud is a water-soluble decorative material that is highly absorbent but not waterproof. Because it does not contain formaldehyde, benzene and other chemical materials, it cannot form a "paint film" and is not suitable for bathrooms, kitchens and other spaces where the walls are often wet with water.

4. Rough touch

Diatom mud does not feel good, it feels rough and uneven. For those who like smooth walls, it is not recommended to use diatom mud to decorate the wall. .
