What is Gypsum board?October 14, 2015
Gypsum board ,also can be called as drywall, wallboard, or plasterboard.,is the name for a family of panel products consisting of a noncombustible core, primarily of gypsum, with a paper surfacing on the face, back and long edges.，also is a type of sheathing used for interior walls and ceilings.Since the mid-1940s, it has been the primary wall construction in most houses.With the development of recent years,the technology of gypsum board production being more and more mature.Therefore,this kind of board has been the mainstream in the engineering of interior/exterior partition wall and suspended ceiling system.
Gysum board can be classified as regular standard gypsum board,moisture proof gypsum board,water proof gypsum board and fire proof gypsum board according to its different characteristics.But the process of making all this kind of gypsum board begins with the mineral being ground and combined with starch to help with adhesion.Depending on the type of gypsum board being made, other trace ingredients might be added at this point,(Such as glass fiber, fire resistant expansion additives,organic hydrophobic agent and so on ).Just enough water is added to create a slurry of the right consistency. Wet gypsum slurry is then sandwiched between two heavy sheets of paper and kiln dried to make the board rigid. The large sheets of wallboard are then cut into standard sizes.
The popularity of gypsum board results from a variety of factors. Firstly, it takes virtually any surface treatment decorationfrom paint or textures to vinyl film and paper laminates. It also lends itself to creative shaping of interior wall and ceilings, allowing the maximum in design flexibility.Secondly, gypsum board is an economical alternative compared to other products. Because it is lightweight, it is easy to handle for installation,which can highly improved the production efficiency .Last but noe least,with its natural properties, it is durable yet easy to repair. In addition, gypsum board have a good command of fire resistance and sound control capabilities ,which further demonstrate its desirability in building systems.
