The LH400 Luhui polyurethane shock-absorbing and soundproofing pad is made of environmentally friendly sound damping materials and PU polyurethane high-temperature and high-pressure molding, demonstrating excellent acoustic performance and excellent sound absorption and shock-absorbing effects. It is the core material of the floating floor soundproofing system. Luhui LH400 soundproof pad is a polyurethane soundproof roll produced using patented technology, which endows the polyurethane soundproof pad with a unique closed cell structure and a series of key acoustic characteristics, providing maximum impact sound insulation effect for floating floor systems. The soundproofing and shock-absorbing pad material has excellent elasticity, low natural frequency, and significant shock-absorbing effect; Wide range of hardness and excellent impact resistance; The rated load range is broad, and customized production can be carried out according to application requirements; High tensile strength and tear resistance, durable and long-lasting; Good mechanical properties, more uniform distribution of load-bearing stress, and stable performance; It has good corrosion resistance, oil resistance, organic solvent resistance, and radiation resistance, with a long service life.

construction process

—

1. When cleaning the base surface, it is necessary to ensure that the base surface is flat, free of sharp objects and protrusions. If the ground flatness is poor, cement mortar should be used to level it before laying the sound insulation pad.

2. Lay sound insulation pads. The joint can be connected by overlapping or flat joint, and the overlapping width cannot be less than 50mm. For flat joint, the joint must be firmly glued with special glue. Seal and cover the joint with tape to prevent cement from entering the joint and causing sound bridges.

3. Fold up the edges of the soundproof pad around the walls, leaving a height of 2-3 times the thickness of the floating layer, and stick it to the wall with adhesive dots. The folded joint should also be tightly glued with tape to prevent the occurrence of rigid connections.

4. According to different ground requirements, lay tiles, floors, and other decorative displays.
