Product Description

Gypsum board, also known as wallboard or drywall, is a plate - shaped artificial building material. The following is a detailed introduction:

- Composition and Manufacturing: Gypsum board is made by adding additives to calcium sulfate (gypsum), extruding it into a plate shape, and then calcining and polishing it. Lightweight aggregates can be added during manufacturing to reduce its own weight and thermal conductivity. Fibers, plasticizers, foaming agents, and some anti - mildew additives are also added to enhance its flame - retardant performance and reduce water absorption.

- Types: According to different raw materials, it can be divided into paper - faced gypsum board and non - paper - faced gypsum board. According to different uses, it includes decorative gypsum board, partition gypsum board, sound - absorbing gypsum board, and ceiling gypsum board. Common types include paper - faced gypsum board, fabric - faced gypsum board, decorative gypsum board, fiber gypsum board, etc.

- Properties and Applications: Gypsum board has the advantages of light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation, and fire prevention. It is widely used in the interior partitions, wall cladding panels, ceilings, sound - absorbing boards, and various decorative boards of various buildings, but it is not suitable for installation in bathrooms or kitchens.

The dimensions of gypsum boards vary depending on their type, purpose, and production standards. Common specifications are as follows:

Length

- Common lengths include 2400mm, 3000mm, and 3600mm. Among them, 2400mm and 3000mm are more commonly used in civil buildings, and can be flexibly selected according to the height of walls or ceilings.

Width

- The widely used width is 1200mm. Some gypsum boards for special purposes may have specifications such as 900mm to meet different construction needs.

Thickness

- The thickness of ordinary paper-faced gypsum boards is mostly 9.5mm, 12mm, and 15mm;

- Special types such as fire-resistant gypsum boards may have a thickness of 18mm or more to enhance their performance.                    

These dimensions are the mainstream specifications on the market. In actual use, they can be selected according to specific decoration designs and requirements for load-bearing, sound insulation, etc.
