Gypsum board without paper (gypsum board) comparison table

Item Gypsum board Paperless gypsum board (fiberglass board)
Material Paper, gypsum powder, additives Gypsum, cement, mesh cloth, perlite, plant yarn and so on
Production Process Paper and filled gypsum bond Through the physical reaction, the internal stability of the formation of high strength and high toughness structure
Sound insulation performance 12 * 2 board +100 keel +
12 * 2 board 50 dB
9 * 1 board +75 keel +9 board 40 dB excellent sound insulation performance
System thickness 148 93mm moderate weight can increase the use of area
Fire-proof level B1 grade flame retardant materials A1 level non-combustible material highest level fireproof material
fire resistance About 1 hour 2.5 hours absolute safety is the petrochemical, paper industry specified materials
Decorative effect As the paper and gypsum moisture absorption after the weakening of the bond strength between the significantly reduced, leading to the plate fragile, easy deformation, poor water resistance, and at the same time easy to mold, yellow, the surface easily from the layer off The surface of a very small amount of putty repair and grinding, can quickly form a smooth coating of grassroots, will not fall off from the layer. Internal material structure is stable, moisture absorption does not reduce its strength
toughness Strength about 3Mpa toughness about 80N impatience impact, can not bend Strength of about 6Mpa toughness of about 800N impact resistance, can be bent, not easy to crack
Service life Because of its own material gypsum and paper bonding, damp, the intensity decreased significantly, the surface is easy to change color, resurgence, cracking droop life 2-3 years need to be renovated The main material is gypsum, cement, grid, perlite, plant sand and other internal physical reaction through the formation of stable high strength and toughness of the crystal structure, the service life so it can maintain the same life with the main building. No need to renovate the second renovation costs
Waterproof Bubble water generally 5 hours (soaked in water, plaster and paper from the basic loss of strength) As the surface of glass fiber reinforced gypsum board without paper, the core composite material by physical reaction forming bubble more than 48 hours without obvious soft phenomenon, can be recovered after drying, which can effectively resist the large-scale decoration works due to leakage caused by the surface off , Mildew and other phenomena, reduce waste and reduce maintenance costs.
Duration As a result of paper, patchwork through a large area, an increase of dry time As the glass fiber reinforced gypsum board surface without paper, the surface has formed a good density gypsum grassroots, special production process to ensure high strength and flatness, just handle the seam, the surface of a small amount of putty repair and grinding, you can Rapid formation of a flat coating base
crack There is paper, can not be the perfect combination of caulking agent fusion, temperature and humidity shadow
Larger, easy to crack
No paper, no moisture, temperature and thermal expansion and contraction will not cause cracks
Environmental comfort Environmental protection (such as using gypsum for filling core material, harmful) Environmental protection and comfortable, does not contain any substances harmful to human health, the surface without paper, direct direct contact with the air, in wet conditions can absorb moisture, moisture can release when dry
application Processing performance, can be sticky, planing, sawing, can be used for indoor ceiling, wall, can be directly nails. Good workability, truly: sticky, planing, nailing, sawing, can be used as a layer of ceiling, partition wall and fire board, floor, decoration board use, can be used to make furniture, cabinets can also be used in Petrochemical, light industry paper industry, can be directly nails
