Gypsum boards are widely used in various engineering projects. Today, I will take you to understand the commonly used types and characteristics of gypsum boards. What are the uses of various gypsum boards made of different materials? There are detailed answers in the article!
1、 What types of gypsum boards are commonly used? Usage scenario?
The gypsum boards produced in China mainly include: paper faced gypsum board, paperless gypsum board, decorative gypsum board, gypsum hollow strip board, fiber gypsum board, gypsum sound-absorbing board, positioning point gypsum board, etc. There are university questions about the use of each type of gypsum board. Let's take a look together~
Paper gypsum board
01 Paper faced gypsum board
Paper gypsum board is a lightweight board made with gypsum slurry as the core and paper as the cover on both sides. Paper gypsum board is lightweight, high-strength, fire-resistant, mothproof, and easy to process. Ordinary paper gypsum board is used for interior walls, partitions, and suspended ceilings. Water resistant gypsum board with fire-resistant treatment can be used for lining walls of rooms with high humidity, such as bathrooms, kitchens, bathrooms, etc. with ceramic tiles, metal plates, and plastic faced brick walls.
Paper gypsum board
Classification of paper gypsum board
ordinary
Ordinary paper faced gypsum board, ivory white paper panel core, and gray board core are economical and common varieties. Suitable for use in places without special requirements, it is recommended to use gypsum boards with a thickness of 12mm or more.
Water resistance
The waterproof paper faced gypsum board has undergone waterproof treatment on its core and protective paper. According to the requirements of national standards, the paper surface and core of the waterproof paper faced gypsum board must meet certain waterproof requirements. Waterproof paper faced gypsum board is suitable for use in bathrooms, bathrooms, etc.
refractory
Refractory paper faced gypsum board, with refractory materials and a large amount of glass fibers added to the core. If the gypsum board is cut open, many glass fibers can be seen from the cross-section. High quality fire-resistant paper gypsum boards will use alkali free fiberglass with good fire-resistant performance, and general products will use medium alkali or high alkali fiberglass. Suitable for indoor partitions, suspended ceilings, and decorative panels with high fire resistance requirements.
Moisture-proof
Moisture resistant paper faced gypsum board has high surface moisture resistance, and is used for ceiling, partition, and veneer walls in rooms with high environmental humidity.
Paperless gypsum board
02 Paperless gypsum board
It is a new type of building board with superior performance, using building gypsum powder as the main raw material and various fibers as reinforcement materials. The application scope has been expanded beyond covering the entire application range of paper paste boards.
Decorative gypsum board
03 Decorative gypsum board
Decorative gypsum board is a board made from building gypsum as the main raw material, mixed with a small amount of fiber materials, etc., with various patterns and decorations, such as gypsum printed board, perforated ceiling board, gypsum relief ceiling board, paper gypsum decorative board, etc. It has the characteristics of lightweight, fireproof, moisture-proof, easy processing, and simple installation. It can be used for decorating walls, making wall panels and skirting boards, and is an ideal material to replace natural stone and terrazzo.
Gypsum hollow strip board
04 Gypsum hollow strip board
Gypsum hollow strip board is a type of hollow board made from building gypsum as the main raw material, mixed with an appropriate amount of lightweight filler or fiber material, and processed. This type of board does not require paper or adhesive, and does not require a keel during installation. Mainly used for interior walls and partitions.
Fiber gypsum board
05 fiber gypsum board
Fiber gypsum board is made from building gypsum as the main raw material and added with an appropriate amount of fiber reinforced materials. It can be used for interior walls and partitions, and can also replace wood to make furniture.
In addition to traditional gypsum boards, there are also new products such as gypsum sound-absorbing boards, fire-resistant boards, insulation boards, and gypsum composite boards. The use of gypsum products is also expanding, and they can also be used as surface decorative materials, and even as floor tiles, exterior wall substrates, and wall core materials.
2、 Characteristics of gypsum board
01 Sound insulation
A double-layer separated sound insulation wall composed of thin plates and a double-layer sound insulation wall composed of hollow strips have a sound insulation effect equivalent to a 24 centimeter thick brick wall, and the sound insulation index can reach 40-50 decibels.
02 Fire prevention
Gypsum board is a non combustible material with certain fire resistance properties, and some can be used as a fire protection layer for steel structures.
03 Strength
When the lateral load of the wall is 250 Pa, the maximum lateral deformation of the wall is not greater than 1/240 of the wall height.
04 Humidity regulation
When the humidity in the air is higher than its own moisture content, gypsum board can absorb the moisture in the air; On the contrary, gypsum board can release moisture from the board and regulate the humidity in the indoor air.
05 Low production energy consumption
The unit production energy consumption of the binder gypsum used for producing paper gypsum board is 78% lower than that of cement.
06 Good decorative function
The surface of the gypsum board is flat, and the boards can be firmly bonded together through adhesive materials, forming a seamless structure with good architectural decoration effect.
07 has good constructability
Gypsum board can be nailed, sawn, and glued, making construction very convenient. Using it for decoration can break away from traditional wet operations and greatly improve construction efficiency.
08 High production efficiency
It is conducive to achieving large-scale production. Among various building boards, gypsum board has a higher production efficiency and is convenient for large-scale production.
09 Low investment
Compared with fiber gypsum board and cement foam board, the production equipment of gypsum board has a high utilization rate and low equipment investment due to its ability to achieve continuous mechanized production.
