Good fire resistance, and it is waterproof, antifreeze, and noxious material, safety and environmental protection will not be discharged.
Glue is injected separately into several grooves of the lower surface difference milling of the upper surface of upper PVC board and lower PVC board, groove,
PVC board and decorative layer and waterproof balance layer are preferably be bonded above and below being conducive to, and strengthen the steadiness on floor, while glue is poly- second
Vinyl acetate glue or polyurethane sealant, with certain anti-flammability, add the anti-flammability on floor.
Strengthening layer is by nonwoven layer and is embedded in the plastic grains on nonwoven layer surface and constitutes, and nonwoven layer is three-decker
Strengthen flexibility, strengthen buffer capacity, while being embedded in the plastic grains enhancing floor on nonwoven layer surface and rubbing for ground
Power is wiped, skidproof effect is good；
A U-shaped groove is provided with vertically along along the width of surface wear-resistant layer, decorative layer, waterproof balance layer and strengthening layer,
A hemispherical groove is recessed on the width of substrate layer, U-shaped groove connects with hemispherical groove so that every piece of ground
Plate after mounting, also may be used by the caking property that can be injected from the U-shaped groove between two pieces of floors between glue, every piece of floor of enhancing
To add the glue of anti-flammability or water proofing property, more effective effect has been reached.
