How to make plasterboard, and about the raw material is important element of drywall is the mineral gypsum. It is a light-density rock discovered in abundant deposits worldwide. Each molecule of gypsum (or dihydrous calcium sulfate) is composed of two mrolecules of water (H two 0) and one of calcium sulfate (CaSO four ). By weight the compound is 21% water, however via quantity it is almost 50% wate. Because the water current in gypsum is in crystalline form, the cloth is dry.

As the Plasterboard manufacturing board strikes down a conveyer line, the calcium sulfate recrystallizes or rehydrates, reverting to its authentic rock state. The paper turns into chemically and automatically bonded to the core. The board is then reduce to size and conveyed thru dryers to get rid of any free moisture.End tapes are utilized that perceive manufacturer, facility, manufacturing line, date and time of manufacture as properly as u . s .

Five Methods to Teach You to Identify the Quality of Gypsum Board, Not to Be Fooled1、 Whether it meets the national standard requirementsDue to the fact that most of the strength of gypsum board comes from the paper surface, which has a fiber distribution direction, the transverse and longitudinal fracture strength of gypsum board is different. The longitudinal/transverse fracture load of gypsum board must meet the requirements of the national standard GB/T9775-1999.
