1 What Are The Raw Materials In Drywall? 2 Drywall Manufacturing Process Mixing Additives With Gypsum Powder Making The Sandwich With Paper Finishing Edges The Panels Are Cut The Drywall Gets Dried The Finished Product Conclusion The most prevalent type of wall covering used in homes across the nation is drywall. There are several advantages, and it is cheaper and easier to install than the plaster that was previously in use.
Gypsum makes up the majority of drywall, therefore its high water content makes it a moderately fire-resistant substance. Gypsum can also be coupled with various additives and specific paper to make walls that are water, mold, and mildew resistant.

WHOSE RAW MATERIALS ARE USED IN DRYWALL? Gypsum is a mineral that is used as the primary ingredient in drywall. Gypsum can be used for a variety of things, such as drywall, plaster, fertilizer, chalk, and blackboards.
Gypsum is used in drywall and sheetrock because it is portable, simple to cut, incombustible, and fire resistant because to its high water crystalline content.
Gypsum is heated and reduced to a powder form, known as plaster of Paris, before being turned into drywall. After that, producers combine additives with this powder to create drywall.
Paper makes up the other essential part of drywall.
Wallboard uses a variety of materials, but most of them are made from recycled newspapers. Manufacturers will occasionally apply foil paper to drywall to create a waterproof surface.
PROCESS OF MAKING DRYWALL A gypsum core is covered with two sheets of paper to create drywall. Here is how to accomplish it:
ADDITIVES AND GYPSUM POWDER ARE MIXED
There are at least two additives combined with plaster of Paris in almost every type of sheetrock. (Remember that plaster of Paris is just gypsum in powder form.)
Starch and paper pulp are the two most used additions.
Paper pulp strengthens the drywall panel, and starch aids in the paper’s adhesion to the gypsum core.
When making drywall, manufacturers may add vermiculite, fiberglass, or clay to increase fire resistance.
Manufacturers combine water, wax or asphalt emulsion, and detergent after mixing the components. They additionally add air to this combination.
The gypsum board is extremely light since the end product contains more than 50% air.
A PAPER SANDWICH BEING MADE
The gypsum slurry is now applied to a piece of paper by the industrial staff. Then another piece of paper is placed on top.
The gypsum and paper are then rolled through a machine to achieve the required thickness.
EDGE FINISHING The sandwiched panels proceed to be edged as they pass through the conveyor belt. Square, tongue-and-groove, and tapered edges are the three most typical styles of edging.
The face paper is edged, then rolled around and adhered to the back.
The panels are broken. The panels are then size-cut after being edged. 48 or 54 inches broad and 8 or 12 feet long are the most typical dimensions.
THE DRYWALL DIES OFF After being cut to size, a worker puts the panels on a conveyor belt to be transported through a drying oven. Typically, this process takes up to 40 minutes.
As the board passes through the oven, the temperature steadily drops from roughly 500 degrees F.
THE COMPLETED ITEM Inspection and sale preparation are the final steps. Each board is individually examined before being put in a bundle.
A UPC is also given to each panel.
CONCLUSION The most typical building material for walls in both homes and businesses is drywall. It is inherently fire-resistant, light, and simple to cut because to the gypsum content.
Gypsum powder is combined with additives to produce excellent drywall for specific types of drywall. When sandwiched between two pieces of specialty paper, this mixture forms a core.
The end result is the drywall you are familiar with and utilize in construction.
