How to Make Plasterboard

How to make plasterboard, and about the raw material is important element of drywall is the mineral gypsum. It is a light-density rock discovered in abundant deposits worldwide. Each molecule of gypsum (or dihydrous calcium sulfate) is composed of two mrolecules of water (H two 0) and one of calcium sulfate (CaSO four ). By weight the compound is 21% water, however via quantity it is almost 50% wate.

Because the water current in gypsum is in crystalline form, the cloth is dry. Although ice, every other structure of crystalline water, turns into a liquid at room temperature, the water certain in the gypsum molecules stays stable except it is heated to 212°F (100°C), at which factor it adjustments to a gaseous nation and evaporates.
Gypsum, known as gypsos via the historical Greeks, is one of the most beneficial minerals acknowledged to man. In its pure structure it is white, however impurities frequently supply it colorations like gray, brown, pink, or black. Ancient Assyrians referred to as it alabaster and made sculptures from it. Today, pulverized gypsum is used for a broad range of applications. It is an ingredient in some manufacturers of toothpaste and is used as a filler in merchandise such as paint, cosmetics, and drugs. Automotive window glass is secured in a mattress of gypsum whilst it is being polished. Gypsum is utilized to farmland as a fertilizer and soil conditioner. An superb supply of calcium, it is used to toughen ingredients such as breads. It is even used to create simulated snowstorms in action pictures.
