What are gypsies?

gypsum panels are building material consisting of large flat sheets of plaster plaster sandwich between two layers of paper. Gypsum panels are also known as plasterboard, wall plate, plasterboard or Sheetrock®. They are used to cover inner walls and ceilings and have gained popularity for being faster, cheaper and easier to use than traditional alternatives. Natural gypsum is obtained by crushing mined gypsum crystals. Synthetic gypsum is created as a by -product of coal or oil burning power plants through the process of gas smoke (FGD). Synthetic and natural gypsum are chemically tied to water, which must be removed before it can be used. This is achieved by the calcinization process in which the gypsum is heated to about 350 ° Fahrenheit (176.7 Celsius) .ter, paper or fibrous fibers and various chemical ingredients to create the plaster. Wet plaster is supplied between two rolls of paper to make the leaves. The leaves are then dried in the furnace and NakParadise on panels. After drying the plasterboard plaster solidifies and pilgrims on paper leaves and creates a solid, durable construction material.

Gypsum panels have been developed to shorten the amount of time to complete the inner walls in the house. Before their invention, the walls were completed using multiple layers of wet gypsum, chaotic and time -consuming process. The first plaster panels were created at the end of the 19th century by Augustin Sackett. These leaves felt wool rather than for wooden pulp paper and were usually used as underlying plaster rather than as completion of the wall. Until 1930, the gypsum panels had more or less achieved their modern form, although improvement in materials and production of curing would continue to the 20th century.

In addition to easy application, plaster panels provide additional benefits. The gypsum is naturally resistant to fire and the panels are usually treated with other fire slowing. When heatedBy fire, the water caught in plaster rolls and lowers the temperature in neighboring rooms. The panels are also usually treated to withstand mold and mold.

The plaster association, the industrial business group, points to the environmental advantages of the use of gypsum panels. They claim that almost 100% of the paper used in production is recycled. The FGD process, which is synthetic gypsum from fossil fuel emissions, keeps sulfur beyond the air and prevents it from becoming solid waste as a building material. In the first first decade of this century, the use of synthetic gypsum increased dramatically and now represents almost a third of the plaster used.
