Fiber cement boards are panels made primarily from cement as the base material and adhesive, reinforced with mineral fiber cement and other fibers, through processes such as pulping, molding, and curing. They are used for fireproof and flame-retardant purposes in cable engineering within power plants, chemical enterprises, and other energy-intensive facilities in China. Additionally, they serve as fireproof and flame-retardant materials for interior decoration in public places such as large shopping malls, hotels, inns, document halls, enclosed clothing markets, light industry markets, and cinemas.    Fiber cement board, also known as fiber reinforced cement board, is a type of building material cement flat sheet produced primarily with fibers and cement, widely used in various fields of the construction industry due to its superior performance. It is categorized into chrysotile fiber cement board and non-asbestos fiber cement board based on the type of fiber added, and into fiber cement non-pressed board and fiber cement pressed board based on the method of molding and pressure application.
