ОГНЕСТОЙКИЕ ПРОДУКТЫ НА ОСНОВЕ СУЛЬФАТА КАЛЬЦИЯ
The present invention relates to a calcium sulphate-based product (e.g. a wallboard) comprising gypsum and a shrinkage resistance additive. The shrinkage resistance additive is a metal nitrate, hydroxide, acetate or sulphate and is preferably provided in an amount greater than 4 wt% (based on the amount of additive and gypsum). The additive may be a nitrate of an alkali metal (e.g. potassium), an alkaline earth metal (e.g. magnesium or calcium), a transition metal (e.g. iron or zinc) or aluminium.
