Uneven quality
At present, there are many brands of diatom mud on the market, with uneven quality and even some fakes. However, due to the lack of professional knowledge, ordinary consumers often can't tell the difference between true and false diatom mud. So you'd better invite professionals to buy diatom mud together to avoid buying fakes.
Higher prices
Because it is a new type of environmental protection material, the cost and price will be higher. The price of a regular product with good quality should be at least 100 yuan per square meter. Compared with other wall decoration materials, the price will indeed be higher, which is unacceptable to many families.
The color is unpretentious.
Because of the use of inorganic pigments, the color looks unpretentious after painting. In addition, its surface has many small holes, so it will appear rough. Because of its special material, it must be constructed by a professional master with technical training, which has certain requirements on construction technology and cannot be painted at home.
Water absorption function detection
Whether it can absorb free water in the air. The judgment method is as follows: wipe the back of your hand with water. Then put the sample on the back of your hand and take it away after 30 seconds. If the back of the hand obviously feels dry, then this template has the function of absorbing the water that is free in the air.
Purification method detection
Sulfuric acid is an industrial waste and its cost is not very high. Diatomite calcined and purified at high temperature not only loses its original physical and chemical properties, but also causes free silicon in your air, which will lead to silicosis for a long time. So, look at purification methods.
Soft texture detection
Diatom mud has the characteristics of soft texture. The made diatom mud wall has a soft feeling like pine, and it feels soft and loose, while the inferior diatom mud feels hard, similar to sandstone.
