Fiber cement boards are panels made from cement as the basic material and adhesive, with mineral fiber cement and other fibers as reinforcing materials, through processes such as pulping, shaping, and curing. They are used for fireproof and flame-retardant applications in cable projects in various power plants, chemical enterprises, and other electricity-intensive locations. They also serve as fireproof and flame-retardant materials for indoor decoration in public places such as large shopping malls, hotels, inns, document halls, enclosed clothing markets, light industrial markets, and cinemas.    Fiber cement boards, also known as fiber-reinforced cement boards, are architectural cement sheets produced primarily with fibers and cement, widely used in various fields of the construction industry due to their superior properties. They are categorized into two types based on the addition of fibers: chrysotile fiber cement boards and non-asbestos fiber cement boards. Additionally, they are differentiated by the molding and pressure process into fiber cement non-pressed boards and fiber cement pressed boards.
