How is plasterboard produced?
What does plasterboard is doing now, cover internal structures such as rays and beams, and provide a flat surface for paper or painting, plaster is used. However, the gypsum took many days to apply for long drying times. In 1916, Sheetrock Sheetrock, a plaster company Sheetrock, invented the plasterboard in the form of boards, as an alternative to plastering to work. The need to build many houses for the Second World War created a demand for Sheetrock, also called a tight or plasterboard. Gypsum on quickly and more efficient.
plasterboard, mainly made of gypsum - abundant mineral, which forms the plaster, is quite cheap to produce. After calculated or cooking plaster, it produces a powder that can be mixed with water to form a paste. When the paste dries, it regains the consistency of the rock. The resulting plaster is dense enough to support its own weight, but not so hard that it cannot be cut with a knife.
The plasterboard manufacturer adds to the gypsumo powder pieces of paper, cotton or glass fibers. Gypsum -made with these fibers is stronger and less susceptible to rupture than pure plaster. Starch, which helps the paper lining glued to the plaster, also goes into the mixture. Once the powder is combined with water, adding a foaming agent introduces air, making the boards easier and easier to use. Gypsum -made from natural mineral with vermiculite is more resistant to fire than other types of plasterboard. Other ingredients include chemicals to reduce mold.
When the gypsum paste is mixed, it is ready to pour on paper. Gypsum, made as painted or otherwise covered, may not look nice and the paper that lines plasterboard, comes from recycled newspapers. It comes in two varieties, light paper for the front of the board and gray paper for the back. On a wide transport belt, and sheet paper is introduced and receives plaster from above. Another leaf rolls over the plaster layer and the entire sandwich with the plaster is then pressedto create the desired plate thickness. Today's plasterboard comes in several standard thicknesses, each focusing on a specific application.
When the conveyor belt is still moving, this very long plate is cut into standard length panels. These panels are then plunged into the furnace of the size of the room to be dried. Here, the boards bake when the temperature gradually reduce until the gypsum core is set. When the boards emerge from the drying chamber, they are ready for use.
plasterboard made such a difference in the way of building buildings that are used in the construction of many houses. The usefulness of plasterboard is abundant and its abundance is very obvious in the locations of the buildings of recently demolished buildings. Gypsum artificons produced by an unstable fracture or moisture cannot be repaired, but can be recycled for use in new plasterboard. The gypsum also has applications as part of cement, fertilizer and as a soil amplifier.
