Specifically, the adhesive may be widely disclosed on the market, for example, any one of polyurethane foam glue and PUI glue (polyurethane polyimide glue). Among them, polyurethane foam (OCF) has a better effect, and polyurethane foam (OCF) is the product of the cross combination of aerosol technology and polyurethane foam technology. It is a special polyurethane product filled with polyurethane prepolymer, foaming agent, catalyst and other components in a pressure-resistant aerosol can. When the material is sprayed from the aerosol can, the foamy polyurethane material will expand rapidly and react with the air or the moisture in the contacted substrate to form a foam. The cured OCF foam has multiple effects such as caulking, bonding, sealing, heat insulation, and sound absorption. It is an environmentally friendly, energy-saving, and easy-to-use building material.

In this embodiment, the kitchen and bathroom wallboard 200 can completely cover the notch on the diversion groove 111 to avoid the notch from being exposed.
