Why is gypsum board a good interior wall of the building material, but can not be used as a wall envelope?
Gypsum board will be broken water, the external walls of long rain so no, and the wall is not the same, and gypsum board can only be used for decoration.
Gypsum board is not waterproof, as the external wall envelope, is unable to resist the rainy weather.
Gypsum board is a good reason for the building's inner wall material:
(1) low production energy consumption. For the production of gypsum board glued gypsum plaster, the unit production energy consumption 78% lower than cement.
(2) light insulation, with gypsum board for the wall, the weight of only 1/3 of the brick wall. At the same time, due to the porous structure of gypsum board, its thermal conductivity is 0.30, compared with brick (0.43) and concrete (1.63), excellent insulation performance.
(3) has excellent fire performance, due to the release of gypsum heat when the water resistance of its resistance to up to 2h or more.
(4) decorative function is good, gypsum board surface smooth, between the board and the board through the cement material can be firmly bonded together to form a seamless structure, building decoration effect is good.
(5) can be a good construction, gypsum board can be nailed, can be saw, sticky, the construction is very convenient, with it to do decoration, you can get rid of the traditional wet operation, greatly improve the construction efficiency.
(6) comfortable living function, because the gypsum board has a unique "breathing" performance, which has the ability to adjust the indoor humidity, so that living comfort.
(7) high production efficiency. Conducive to the realization of large-scale production, in a variety of building plates, gypsum board production efficiency is the highest, easy to large-scale production.
(8) low investment Gypsum board production equipment and fiber gypsum board, compared to cement puff board, due to the realization of continuous mechanized production, equipment utilization is very high, less equipment investment.
