Fire board is currently the most commonly used material on the market. There are two commonly used: one is high-pressure decorative refractory board, which has the advantages of fireproof, moisture-proof, wear-resistant, oil-resistant, easy to clean, and more varieties of colors. One is the glass magnesium fireproof board, the outer layer is decorative material, the inner layer is mineral glass magnesium fireproof material, can resist 1500 degrees high temperature, but the decoration is not strong. Fire-resistant suspended ceilings are installed at building exit passages, stairwells and corridors to ensure safe evacuation in the event of a fire and to protect people from spreading fire.

The relevant inspection report pointed out that the formaldehyde emission of building materials directly used indoors must be less than or equal to 1.5 mg per liter. If the formaldehyde emission is less than or equal to 5 mg per liter, it must be treated with finishes before it can be used indoors. The formaldehyde emission exceeds 5 mg per liter is substandard. Bringing unqualified wood home is like adding a poisonous gas machine to a new home, so buying boards must first look at environmental protection.
