What is the production process of rock wool board? Let's follow Nanjing rock wool board manufacturer Zhongrunda New Materials Company to learn more!


The rock wool insulation board mainly uses high-quality basalt, dolomite, and other raw materials. After being melted at high temperatures above 1450 ℃, it is spun into fibers using an internationally advanced four axis centrifuge at high speed. At the same time, a certain amount of adhesive, dustproof oil, and hydrophobic agent are sprayed into it. After being collected by a cotton collector, it is cured and cut using a pendulum method and three-dimensional cotton laying method, forming exterior wall rock wool insulation board products of different specifications and purposes.


Production process: the raw materials are fully melted by the cupola and spun by the high-speed centrifuge to form rock wool fiber, which is sprayed and cooled by the high-speed blower. During the injection process, a certain proportion of efficient adhesive is added, and the uniform cotton distribution is made by the large pendulum equipment, so that the rock wool collodion is in a three-dimensional cotton distribution state and evenly distributed on the track. The laid rock wool is transported by the track to the pressure equipment to form a certain density of rock wool board, which is then sprayed into the rock wool through a high-temperature drying furnace. The efficient adhesive acts efficiently to bond the rock wool into a whole. After the rock wool board is high-temperature dried, the paper is sent to cool the air outlet, allowing it to cool down.


In the process of being transported to the cutting equipment through the track, the cutting equipment adjusts the cutting size accordingly according to different specifications. The longitudinal cutting method is used to form a length rock wool board, and then the saw blade is cut in parallel motion at the same speed as the conveyor belt. Horizontal cutting is used to form a rock wool board with the same specifications; After high air blowing, the slag is overlapped in parallel to reach the packaging thickness. The rock wool insulation board is packaged as a whole using a fully automatic heat shrink packaging machine, and the packaging is shrunk through a heat shrink furnace. After cooling, it is transported by a finished product transport vehicle to the finished product inventory for storage.
