Abstract
Gypsum board is conventionally used for the interior of the building, especially on the roof and in the vicinity of cooling and heating sources. Gypsum board, unlike wood and iron, absorbs from the environment and emits. This defect causes the gypsum board to prevent the medium from reaching the optimal level of consumption. The purpose of doing this research is to be able to make plasters that perform better in the conditions. It means that gypsum board has good thermal conductivity in addition to having standard resistance. These types of waste paper fibers, wool, polyester and goat hair, with two additives, pigment, and copper sulfate are used to make fibrous plasterboard. The two main factors of fibers in five levels and additives in three levels and overall structure in 15 treatments are investigated. The optimal ratio of the amount of combined materials will be selected based on trial and error. The presence and size of these compounds can create suitable resistance and thermal properties in plasterboard. To measure the effect of each treatment, tests such as thermal expansion, water absorption rate, bending strength, internal adhesion and time-consuming tests are performed according to the Iranian national standard. Based on the results of the best boards, the boards were the controls. Such a favorable thermal conductivity coefficient is shown in the copper sulfate reference board. The reason is the presence of copper sulfate, which increases the thermal conductivity of the board. Copper sulfate is on the side of metals in the periodic table of elements and plays a role in thermal conductivity properties like metals. It is recommended to use copper sulfate control boards in the best and optimal mode for the exploitation and production of plasterboard, and in other conditions, use boards with polyester fibers and copper sulfate.
