The main material for the production of plasterboard is plaster, which is mixed with special additives and after adding water and becoming a paste, it is placed between thick paper plates and is ready for use after drying. One of the most important additives in plaster production is starch. Starch is used to glue paper to plaster. The strong connection between paper and plaster plays an important role in the strength of plaster. The suitable starch for this purpose is a modified starch that should be able to spread evenly in the dough and also have sufficient adhesion.

Gold gypsum starch is a modified starch that binds to gypsum crystals by protecting them

The paper makes the connection between paper and plaster strong and stable. These crystals, which are located on the surface, are prone to excessive dehydration and breakage during placement in the oven at high temperatures. Excessive dewatering causes the paper to separate from the plaster. This starch prevents excessive dehydration of these crystals by maintaining moisture during baking. Below is the analysis of gypsum starch.
