laminated gypsum board
The primary component of laminated gypsum board is gypsum, a naturally occurring mineral composed of calcium sulfate dihydrate. The manufacturing process involves heating gypsum to create calcium sulfate hemihydrate, commonly known as plaster, which is then combined with additives to enhance its properties. This mixture is spread between two layers of heavy, durable paper or composite materials, after which it undergoes drying and cutting to form sheets of various sizes.
