ECO-FRIENDLY Fireproof gypsum board is a combustible material belonging to B1 level, that is, a building material belonging to the flame retardant level. According to the classification of flammable grades of Chinese building materials, they include: 1. Class A, non-combustible. 2. Class B1, flame retardant. 3. Class B2, flammability. 4. Class B3, flammability.

The type, quality, number of layers of gypsum board used by ECO-FRIENDLY Fireproof gypsum board and the quality of keel, installation method, joint treatment and other minor joints will affect the fire performance of the system.

ECO-FRIENDLY Fireproof gypsum board as a new type of building material, what are the performance characteristics:

(1) Low production energy consumption and high production efficiency: the energy consumption of producing the same unit of ECO-FRIENDLY Fireproof gypsum board is 78% less than that of cement. Moreover, the investment is small, the production capacity is large, the process is simple, and it is convenient for large-scale production.

(2) Lightweight: ECO-FRIENDLY Fireproof gypsum board is used as the partition wall, the weight is only 1/15 of the brick wall of the same thickness, and 1/10 of the block wall, which is conducive to the structure's earthquake resistance and can effectively reduce the foundation and structure. Main cost.

(3) Thermal insulation: About 60% of the core of the ECO-FRIENDLY Fireproof gypsum board is tiny air holes, because the thermal conductivity of air is very small, so it has good lightweight thermal insulation performance.

(4) Good fireproof performance: Since the gypsum core itself is non-combustible, and when it encounters fire, it will absorb a large amount of heat during the process of releasing hydrated water, delaying the rise of the ambient temperature. Therefore, ECO-FRIENDLY Fireproof gypsum board has good fireproof performance Flame retardant properties. Tested by the National Fire Protection Testing Center, the fire resistance limit of the gypsum board partition wall can reach 4 hours.

(5) Good sound insulation performance: the single-layer wall composed of a single lightweight material, such as aerated concrete, expanded perlite board, etc., can meet the sound insulation requirements only when the thickness is large, while the ECO-FRIENDLY Fireproof gypsum board partition wall With a unique cavity structure, it has good sound insulation performance.

(6) Good decorative function: ECO-FRIENDLY Fireproof gypsum board has a smooth surface, and the joints between the boards form a seamless surface, and the surface can be directly decorated.

(7) Convenient processing and good constructability: ECO-FRIENDLY Fireproof gypsum board has the properties of nailing, planing, sawing, and sticking. It can be used for interior decoration and can achieve ideal decorative effects. It only needs to be cut with a knife. The gypsum board can be cut at will, and the construction is very convenient. Using it as a decorative material can greatly improve the construction efficiency.

(8) Comfortable living function: Due to the large porosity of the gypsum board and the proper distribution of the pore structure, it has high air permeability. When the indoor humidity is high, it can absorb moisture, and when the air is dry, it can release part of the moisture, thus playing a certain role in regulating the indoor humidity. This function of plasterboard is called "breathing" function in foreign countries. It is precisely because of this unique "breathing" performance of gypsum board that it can adjust the indoor humidity within a certain range and make the living conditions more comfortable.

(9) Green and environmental protection: ECO-FRIENDLY Fireproof gypsum board uses natural gypsum and paper as raw materials, and never contains asbestos that is harmful to human body (most calcium silicate boards and cement fiber boards use asbestos as the reinforcing material of the board) ).
