Speaking of gypsum board, I believe we will not be unfamiliar, it is the most widely used decorative materials in home decoration, it can not only carry out ceiling decoration, but also wall and floor decoration. In modern society, people's most concerned about decoration is environmental protection. Does gypsum board contain formaldehyde? What advantages does gypsum board have? The following small series will share these problems with you.

Gypsum board is the use of building gypsum as raw materials, through a certain processing technology produced, so it does not contain toxic substances, is a very environmentally friendly building materials. However, it will be used in the production process of certain glue, and the glue contains a certain amount of formaldehyde, so it can not be said that there is no formaldehyde at all.

I. decoration materials

The reason why gypsum board can be accepted by many consumers is that it has the irreplaceable role of other decorative materials. Gypsum board has the characteristics of light weight. The weight of gypsum board is lighter than that of brick wall. The weight of gypsum board is only 1 / 15 of that of brick wall with the same thickness, and 1 / 10 of that of block wall. Such weight is conducive to the construction of complex decoration structure, reduce the weight and cost of the main structure, and is conducive to earthquake resistance.

2、 Thermal insulation

Compared with other building materials, gypsum board has better thermal insulation properties, because gypsum board can add a variety of materials in the production process to produce different types of gypsum board. The porous structure enables gypsum board to have the effect of thermal insulation. The thermal conductivity is 0.16w / (m.k), which is more significant than that of lime sand brick (1.1W (m.k)).

3、 Fire prevention

Compared with other building materials, gypsum board also has better fire resistance characteristics, because gypsum board is made of building gypsum, and gypsum itself has fire retardant characteristics. It will absorb a lot of heat in the process of releasing the combined water when encountering fire. The fire resistance of gypsum board partition wall can reach 4 hours.

4、 Convenient and easy to cut

Gypsum board construction is also very convenient, we can use the cutting knife to cut the gypsum board, and can make a variety of different shapes, very beautiful. Its cut into the ceiling is a common feature.

In addition to the above advantages, gypsum board also has good sound insulation effect and decoration function. The above is the relevant sharing of formaldehyde in gypsum board.
