What is the main function of the protective paper of gypsum board?

1. Low weight: gypsum protective paper 180-200g m2; However, at the same time, it has high tensile strength, which can meet the strength requirements of high-grade gypsum board production line; The finishing performance is unique, and the gypsum board produced is very flat, which is the preferred protective fabric for the production of large and medium-sized high-grade gypsum board.

Second, high air permeability: gypsum face paper products breathe a large space, suitable for the evaporation of a large amount of water vapor when drying in gypsum board production, which is the fundamental foundation of today's large-scale gypsum board production line, which helps gypsum board customers to increase production and efficiency.

3. Good heat permeability: gypsum protective paper is convenient for the control of shaping, slitting and flapping in the production process of gypsum board, and maintains the strength of the paper wet, which helps the board line to improve the yield rate.

Fourth, the appearance quality is good: the front of the gypsum protective paper is the standard ivory white color, and the conventional thermal dispersion technology and eco multi-stage flotation deinking are used in the pulping and pulping; The first gypsum board face protection paper in China to rinse the batter at high speed, which alleviates the easy fading of the outside of gypsum board and stabilizes its appearance quality.

Fifth, composite force: the surface strength of gypsum protective paper is high, and the molding of paper is laminated and compounded. The batter needs to be treated by a special process, and the interlayer bonding and surface strength of the protective paper are improved, which effectively controls the paper delamination in gypsum board production.

6. Fiber raw materials of the product: gypsum protective paper is made of selected waste paper, which saves resources and reduces the environmental pollution caused by chemical pulping.

7. Product quality: gypsum paper is conducive to reducing costs, improving competitiveness and expanding gypsum board in the domestic market. The use of clay bricks and timber in the construction industry is in line with the national policy requirements of saving arable land, saving energy, and improving environmental protection, and has good social benefits.

The strength of gypsum board is 80%** of gypsum paper, and without it, the gypsum core has almost no strength. You can do an experiment by peeling off the face shield and using a little force with your hands, the plaster block will break.

Gypsum board is a type of gypsum board, and there is no difference. Gypsum board includes gypsum board, decorative gypsum board, sound-absorbing gypsum board, refractory gypsum board, etc.

The gypsum board is used as the sandwich layer in the middle of the gypsum slurry, and the kraft paper is used as the surface protection on both sides, so it is called the gypsum board, which has the advantages of smooth surface, excellent stability, fire prevention, easy processing and simple installation.

In gypsum board, the water-resistant gypsum board with water-resistant admixtures has excellent water and moisture resistance, and can be used for space walls such as bathrooms and kitchens with high humidity.

Summary. Ordinary gypsum board: ivory white core, gray paper, is a particularly economical and commonly used variety, limited to the use of places without special requirements, the continuous humidity of the use of the place is not more than 65%.

Because of the best reasons, many people like to use thick ordinary gypsum board to make ceilings or walls, but because ordinary gypsum board is relatively thin and not high in strength, it is easier to deform again under wet conditions, so it is recommended to use gypsum board above 12mm. At the same time, the use of hard sheets is also an effective means to prevent joint cracking.

What is the paper gyplight used for.

Hello dear, I am a gold medal mentor of cooperation, I have provided a total of 1w people with a cumulative service time of more than 3000 hours! I have received your question, it will take some time to answer, please wait a while, it will take 5 minutes to get the result, please do not end the consultation, you can also provide more effective information, so that I can better answer for you If my answer is helpful to you, please give it a thumbs up, thank <>

<> gypsum board is a lightweight building board made of natural gypsum as the main raw material (without asbestos harmful to the human body), mixed with an appropriate amount of fiber, starch, coagulant, foaming agent and water. Gypsum board can be divided into four categories: ordinary gypsum board, water-resistant gypsum board, refractory gypsum board, and moisture-proof gypsum board.

Ordinary gypsum board: ivory white core, gray paper, is a particularly economical and commonly used variety, limited to the use of places without special requirements, the continuous humidity of the use of the place is not more than 65%. Because of the best reasons, many people like to use thick ordinary gypsum board to make ceilings or walls, but because ordinary gypsum board is relatively thin and not high in strength, it is easier to deform again under wet conditions, so it is recommended to use gypsum board above 12mm.

At the same time, the use of hard sheets is also an effective means to prevent joint cracking.

I hope my answer is helpful to you, please give a thumbs up (comment in the lower left corner), look forward to your like, your efforts are very important to me, and your support is also the driving force for my progress. If you feel that my answer is still satisfactory, you can click on my avatar for one-on-one consultation. Finally, I wish you good health and a good mood!

When decorating a new house, many owners are not very satisfied with the original layout, and will make some partition walls to divide the internal space. There are many types of partition wall brands on the market, among which the gypsum board partition wall is deeply loved by the public, what are the characteristics of gypsum board?

1. Low energy consumption in production: gypsum board can save 78% of energy consumption compared with traditional cement partition walls. The cost is low, the production capacity is large, and the process is simple, which is convenient for large-scale production.

2. Lightweight: gypsum board itself is a lightweight product, and its weight is only about 1 15 of the same thickness of brick wall, which is conducive to the seismic resistance of the structure and effectively reduces the cost of the main body of the structure.

3. Thermal insulation: The core of the gypsum board contains tiny pores, so it has good lightweight thermal insulation performance.

4. Good fire performance: because the gypsum core itself is a non-combustible material, even if it accidentally encounters fire, it will automatically absorb a lot of heat, delay the increase of the surrounding ambient temperature, and have good fire retardant performance. Tested by the National Fire Protection Testing Center, the fire resistance limit can be as long as more than 4 hours.

5. Good sound insulation performance: the traditional wall needs to be very thick to meet the sound insulation effect, while the gypsum board partition wall itself has a good cavity structure and has good sound insulation performance.

6. Good decoration function: the surface of the gypsum board is flat, and it can be directly decorated to achieve seamless docking.

7. Convenient processing: gypsum board has the functions of nailing, planing, sawing, etc., suitable for interior decoration, to achieve the ideal decorative effect, and can be cut at will, which is convenient for construction and greatly improves construction efficiency.

8. Comfortable living function: due to the large porosity of gypsum board itself, it has good air permeability. It can automatically play a certain role in regulating the indoor humidity, which is what we often call the "breathing" function, making the living conditions more comfortable.

9. Green environmental protection: the gypsum board directly uses natural gypsum and paper as raw materials, does not contain asbestos harmful to the human body, and makes the gypsum board partition wall green and environmentally friendly, without worrying about the release of harmful substances.

10. Space-saving: the use of gypsum board partition wall, the thinnest wall thickness can reach 74mm, effectively ensure the sound insulation and fire performance of the wall.
