These types of gypsum boards are produced with special additives to reduce water absorption ratio and are classified as H1, H2, H3. Type H gypsum boards (moisture resistant) It is the most common used and widely produced type of gypsum board. Most preferred gypsum boards types as shown above are Type A, H and F. In the same way, thickness of gypsum boards varies from 6mm to 18mm.Įdges of gypsum boards may have different shapes, such as tapered edge or square edge In the before mentioned standard (EN520+A1) gypsum board types are described as Type A, H, F, E, P, I, R and D, and dual or trio versions (e.g. Gypsum boards, as briefed above, are differ from each other in production technology according to are of use, thickness and length as described inEN520+A1 standards. Dried gypsum boards are trimmed in bundler unit and then packed for further dispatch to customers. Gypsum board after obtaining required setting is cut in length by the cutting knife and then transferred to dryer unit. Cardboard edges and sides are bended and required thickness is obtained in forming unit, and continues on long belt conveyor for setting. Gypsum powder, water and wet & dry additives are fed to high-speed mixer where homogenous mixture is prepared, and then the mixture is poured into two layers of cardboard prepared in the production line. Gypsum powder, produced with a calcination process under suitable conditions in gypsum production process, stored in silos for further use in gypsum plasterboards production. In order to produce gypsum plasterboard, first, you need gypsum powder production process. Depending on area of use, gypsum boards are selected as per their type, form, thickness and edge shape, and are used as dry surface sheeting, suspended ceiling covering, wall partitioning elements or curtain covering on supporting beam or columns. Gypsum are fixed on to the surface by means of nails, screws and gypsum-based adhesives and other various types of adhesives.
