magnesium sulfate mgo board is a new type of
muti-functional building materials with magnesium oxide and magnesium sulfate
as the raw materials, also mixing the perlite, fiber glass mesh, saw dust in a
certain proportion.
Property
of sulfate board
>Impervious to water, fire,
insects and chemicals
>Light weight and easy for
installation
>Tough, anti-abrasion
>Non-toxic, safe and
eco-friendly
Application for magnesium sulfate mgo board
+Partition board
+Interior & exterior wall
panel
+ Ceiling board
+ Flooring
+ Lining of fireproof board
+ Core of fireproof door
+ Prefabricated houses
(1) Fireproof Board
magnesium sulfate mgo board was
tested by the National Center for Quality Supervision and Testing of Fire
Building Materials (NFTC). Its fireproof level is rated level A (nonflammable
level);
(2) Moisture Resistance
magnesium sulfate mgo board is
excellent in moisture resistance. Dry bending strength is 15Mpa. Bending
strength under absorbed moisture is 22Mpa;
(3) Heat Insulation
magnesium sulfate mgo board has
heat prevention material incorporated, it has great feature of heat prevention.
Thermal resistance is 1.14m2k/w;
(4) Sound Insulation
magnesium sulfate mgo board is
proved to have good noise insulation property after inspected by the National
Center for Quality Supervision and Testing of Fire Building Materials (NFTC).
The noise insulation factor of the wall can reach 44dB and 47dB. It has the
best noise insulation constitution in China, especially the 95mm wall comprised
by the 10mm board.
(5) Bump-resistance and light
magnesium sulfate mgo board is
a light board. Its density is less than 1300kg/m3. At the same time its bending
strength and impact resistance is excellent. Also, it will maintain its'
quality during construction. It is light, it can save time, space, weight and
expense. It is a new and high efficient wall
