Plasterboard Production Machine

Water is brought to the plaster of Paris mixture to shape a slurry of the appropriate consistency. An asphalt emulsion and/or a wax emulsion is brought to acquire the favored degree of moisture resistance in the remaining product. A foaming agent such as a detergent is included, and in the course of the mixing technique air is entrained into the material. The completed gypsum panel will be over 50% air; this minimizes the board's weight and makes it less difficult to cut, fit, and nail or screw to the framing. Glass fibers are delivered to the moist core fabric when making firerated gypsum board.

Making the sandwich
The gypsum slurry is poured onto a layer of paper that is unrolling onto a lengthy board machine. Another layer of paper unrolls on pinnacle of the slurry. The sandwich then passes via a gadget of rollers that compact the gypsum core to the appropriate thickness. The most frequent thicknesses are 0.37 inch (9.5 mm), 0.5 inch (12.7 mm), and 0.62 inch (15.7 mm).
Finishing the edges
Automated meeting strains in gypsum board flora vary from 300-800 toes (93-247 m) long. As the drywall continues alongside the conveyor belt, the edges are formed. Various shapes of edges are possible, relying on the closing use of the panel. Options encompass the common rectangular edge, a tongue and groove type, tapered and/or beveled edges, and even rounded edges.
