In conclusion surface provided by the invention has the gypsum sheet material of composite glass fiber facing felt, there is good fire prevention
Fire-retardant, sound insulation and noise reduction, it is water-fast mould proof the effect of, after being combined with plasterboard sandwich layer, substantially increase the service life of gypsum sheet material
With the performance indicator under particular surroundings, plate surface fiber is fine and close smooth elegant and graceful, can spray various coating according to demand, increases
Strong individual decoration effect, is widely used in the engineerings such as hotel, shopping, meeting, office, local-style dwelling houses.Therefore, the present invention is gypsum
Plank promotes the precondition of more application fields, is suitble to large-scale promotion application.
It is limitation of the present invention that above description, which is not, and the present invention is also not limited to the example above, the art
The variations, modifications, additions or substitutions that technical staff is made in the essential scope of the present invention should also belong to the protection of the present invention
Range.
