One、The specifications of fireproof boards are generally
1. Commonly used fireproof board specifications include 2135mm x 915mm, 2440mm x 915mm, and 2440mm x 1220mm, with a thickness of 0.6-1.2mm.
2. The specifications for fire-resistant boards are generally as follows: Fire-resistant boards are manufactured by pressing and laminating fire-resistant materials onto wood. Common thicknesses are 0.8mm, 1mm, and 1.2mm. Common substrate thicknesses include 16mm and 18mm. The thickness of the fire-resistant board after lamination is typically between 17mm and 19mm.
II. Fireproof Board Technical Standards
1、Fire-resistant board's physical and chemical properties
(1) Dry flexural strength exceeds 11 MPa, achieving 24 MPa, which meets the standard.
(2) When the flexural strength reaches a value of 6 MPa or higher in a saturated absorption state, it achieves a value of 18 MPa, which meets the requirements.
(3) The moisture deformation rate is less than 0.35%, with a result of 0.32%, which meets the standard.
(4) The shrinkage rate at elevated temperatures is less than 2.0%, with a result of 1.8%, which meets the requirements.
(5) Density value greater than 1.30 g/cm3, meets the requirements.
2、Fireproof board fire resistance performance
(1) The temperature rise within the furnace is less than 50℃, reaching 17℃, which meets the requirements.
(2) If the continuous burning time is less than 20 seconds, the result is 0 seconds (classified as non-combustible), which meets the requirements.
(3) The loss rate is less than 50.00%, with a result of 45.82%, which meets the standard.
