The gypsum board currently produced in China mainly includes: gypsum board, decorative gypsum board, gypsum hollow board, fiber gypsum board, gypsum sound-absorbing board, positioning point gypsum board, etc.
(l) Gypsum board paper. The gypsum board is a kind of lightweight board made of gypsum slurry as the core and double-sided paper as the face. The gypsum board is light in texture, high in strength, fireproof, anti-mite and easy to process. Plain plasterboard is used for interior walls, partitions and ceilings. The fire-resistant water-resistant gypsum board can be used for wall surfaces of rooms with high humidity, such as linings for tiles, metal plates and plastic brick walls in bathrooms, kitchens and bathrooms.
(2) Decorative plasterboard. Decorative gypsum board is made of building gypsum as the main raw material, with a small amount of fiber material, etc., which has various patterns and floral decorations, such as gypsum printing board, perforated ceiling board, gypsum embossed ceiling board, paper plaster decorative board Wait. It is a new type of interior decoration material, suitable for medium and high-grade decoration, featuring light weight, fireproof, moisture proof, easy processing and simple installation. In particular, the new resin imitation facing waterproof gypsum board is covered with resin and the surface is patterned, the tone pattern is realistic, novel and generous, the sheet is high in strength, resistant to pollution and easy to clean. It can be used to decorate the wall and be used as a retaining wall. Plates and skirting boards are ideal materials to replace natural stone and terrazzo.
(3) Gypsum hollow strips. The gypsum hollow strip is a kind of hollow board which is made by building gypsum as the main raw material and adding appropriate amount of light filler or fiber material. This kind of sheet material does not use paper and adhesive, and it does not need keel when it is installed. It is a kind of lightweight board which develops faster. Mainly used for interior walls and partition walls.
(4) Fiber gypsum board. The fiber gypsum board is made of building gypsum as the main raw material and is blended with appropriate amount of fiber reinforced materials. This sheet has a higher flexural strength than paper gypsum board and can be used for interior and partition walls, as well as for wood.
In addition to the traditional gypsum board, there are new products, such as gypsum sound-absorbing panels, fire-resistant panels, insulation panels and gypsum composite panels. The specifications of the gypsum board are also developing in the direction of high thickness and large size.
(5) Plant straw plasterboard. Different from ordinary plasterboard, it uses a large amount of plant straw to make full use of local waste, which not only solves environmental problems, but also increases farmers' economic income, and reduces the weight of gypsum board and reduces it. The transportation cost, while reducing the consumption of coal and electricity by 30%-45%, is in full compliance with the relevant national industrial policies.
(6) Positioning point gypsum board 2nd generation gypsum board - Bayer positioning point gypsum board
This product is a new generation of patented gypsum board products that are successfully developed by Bayer due to the actual needs of Bayer Engineering and meet the national construction specifications. This product is made of Bayer's proprietary high-grade white wood pulp facing paper and high-quality gypsum and other raw and auxiliary materials. The surface of the product is whiter and pre-set in the construction surface of the gypsum board according to the requirements of national construction codes. Construction installation and positioning points make the project construction better and faster.
In addition, the use of gypsum products is also broadened, in addition to being used as a base lining, as a surface decoration material, and even as a floor tile, an exterior wall substrate and a wall core material.
DIY diamond blades are designed for cutting concrete, natural stone, and other kinds of residential materials. Used on angle grinder, they're mainly using for cutting granite, tile, ceramic tile and making grooves on the surface on construction materials, removing cement mortar joints, with stable performance and high efficiency. Continuous rim blades are for wet use, while segmented blades are for dry use and turbo segments are offering fast and smooth cutting in different materials.Even, silent and normal blades are available for your choices.
