Description
Technical field
The invention belongs to building material field, be specifically related to a kind of plasterboard for construction wall.
Background technology
Along with the development that urbanization is carried out, the requirement of people to material of construction is also more and more higher.At present, in construction wall, plasterboard uses more material of construction.Plasterboard take plaster of Paris as the one that main raw material is made
material.It is a kind of lightweight, intensity is higher, thinner thickness, easy to process and sound insulation is adiabatic and the material of construction of the better performances such as fire prevention, is one of novel light sheet material of current development emphatically.Plasterboard be widely used in the internal partition wall of the various buildingss such as house, office building, shop, hotel and industrial premises, body of wall cladding boards (replacement floated coat),
top ceiling,
acoustic panel, surface based laminate and various decorative sheets etc.In addition, the purposes of plastering is also constantly being widened, and except making such use, is also used as floor tile, exterior wall substrate and body of wall core etc.
The plasterboard that state produces mainly contains Thistle board, decorated gypsum board, gypsum hollow lath, fibrous plaster, plaster board, locating-point plasterboard etc.1) Thistle board.Thistle board take Gypsum slurry as sandwich, and two sides paper using is as a kind of light weight board of mask.Thistle board quality is light, intensity is high, fire prevention, mothproof, be easy to processing.Common paper surface gypsum board is used for interior wall, partition wall and furred ceiling.Wet-strong paper surface gypsum board through fire prevention process can be used for the larger room metope of humidity, as the liner plate of the tilings such as toilet, kitchen, bathroom, metal sheet, plastic cover brick wall.2) decorated gypsum board.Decorated gypsum board take plaster of Paris as main raw material, the sheet material having multiple patterns, floriation that a small amount of filamentary material of admixture etc. is made, as gypsum printing plate, perforation ceiling board, gypsum embossed hung ceiling plate, Paper-faced gyp decorative lamination decoration board etc.It is a kind of novel house decorative material, is applicable to medium-to-high grade decoration, has lightweight, fire prevention, protection against the tide, easily processes, installs the features such as simple.Particularly new type resin imitates type veneering water-proofing plasterboard plate face coated with resin, and facing imitates type decorative pattern, and its tone pattern is true to nature, novel generous, timber intensity is high, anti-pollution, easy cleaning, can be used for decorated wall surface, doing wall dunnage and baseboard etc., is the ideal material replacing lithotome and terrazzo.3) gypsum hollow lath.Gypsum hollow lath take plaster of Paris as main raw material, a kind of hollow plate of the appropriate light filler of admixture or filamentary material post-treatment.This sheet material is paper using and binding agent not, without keel during installation, is develop than faster more a kind of light weight board.Be mainly used in interior wall and partition wall.4) fibrous plaster.Fibrous plaster take plaster of Paris as main raw material, and the appropriate fiber reinforced material of admixture is made.The bending strength of this sheet material, higher than Thistle board, can be used for interior wall and partition wall, and timber also can be replaced to make furniture.5) straw Thistle board.Be different from common Thistle board, it is because adopting a large amount of plant straws, local refuse is fully used, both environmental issue was solved, turn increase the income of peasant, make again the weight saving of plasterboard, reduce transportation cost, decrease the consumption 30%-45% of coal, electricity simultaneously, meet the industry policy that country is relevant completely.
At present, there is waterproof anti-moisture performance in the plasterboard as interior wall, folding strength, resistance to impact shock low mostly, and the defect such as the harmful gas capacity difference of absorption.
