How about Wanhua Hexiang Board? What are its advantages and disadvantages?

Wanhua hexiang board is a kind of board that does not release formaldehyde. It uses agricultural and forestry residues such as crop straws and fruit branches as main raw materials, and uses Wanhua polyurethane ecological adhesive to replace urea-formaldehyde resin used in traditional wood-based panels. No formaldehyde is added, which ends the history of the inevitable release of formaldehyde from wood-based panels. The produced board has the advantages of durability, flame retardancy, moisture resistance, sound absorption, etc., and all the properties meet or exceed the national standards.

The key to formaldehyde-free release of Wanhua Hexiang board is the polyurethane adhesive produced by Wanhua Chemical. The polyurethane adhesive added in the incense board comes from MDI of Wanhua Chemical, which is the general name of a large class of chemical adhesives and the most important raw material for producing polyurethane. It does not release formaldehyde, and its environmental protection performance has also passed the certification of NAF Environmental Protection Bureau and NAF carbohydrate in California.

superiority

1, robustness, durability, load-bearing and deformation resistance of incense board reach the national particleboard standard, which is no less than that of wood-based board.

2. Good moisture resistance. There are a lot of natural wax layers on the surface of straw fiber raw materials used in incense boards, which have moisture-proof and waterproof functions similar to paraffin additives in moisture-proof boards.

3, flame retardant, straw fiber is rich in silicon dioxide, which belongs to natural fireproof substances. Its combustion performance meets the requirements of GB8624-B2.

4. It has the functions of sound insulation and sound absorption. Incense board is a homogeneous porous material with good sound absorption performance.
