Wall decoration is the key to home decoration. As the decoration materials are more and more diversified, new wall decoration materials are currently popular, but many people do not know about new wall decoration materials. I don’t know that new wall decoration materials have Which, the following small series to tell you what is the best new wall decoration materials.

First, the paper gypsum board

The gypsum board is made of building gypsum as the main raw material, with the appropriate amount of additives and fibers as the core, and the special board paper as the protective surface. The gypsum board has the characteristics of light weight, sound insulation, heat insulation, strong processing performance and simple construction method.

Features:

1, water resistant

The core and the facing paper are waterproofed. According to the requirements of the national standard, the paper surface and core of the water-resistant paper gypsum board must meet certain waterproof requirements (the surface water absorption is not more than 160 grams, and the water absorption rate is not more than 10). %). Water-resistant paper gypsum board is suitable for use in places where continuous relative humidity does not exceed 95%, such as toilets and bathrooms.

2, fire resistance

A refractory material and a large amount of glass fiber are added to the core, and if the gypsum board is cut, a lot of glass fibers can be seen from the section. Good quality fire-resistant gypsum board will use non-alkali glass fiber with good fire resistance. General products use medium or high alkali glass.

3, moisture

It has high surface moisture resistance, surface water absorption is less than 160g/m2, and moisture-proof gypsum board is used for room ceiling, partition wall and veneer wall with large environmental tidal.

Second, the gypsum block

Gypsum block: Lightweight building gypsum products made of building gypsum as the main raw material, stirred by water, cast and dried. Fiber reinforcement or light aggregates may be added during production, and a blowing agent may also be added. It has many advantages such as sound insulation and fireproof, convenient construction, etc. It is a new type of wall material with low carbon environmental protection, health and meeting the development requirements of the times.

Features:

1. Safety: Mainly refers to its good fire resistance. Fire protection: This is mainly because dihydrate gypsum (CaSO4·2H2O) contains two crystal waters, accounting for about 21% of the total weight. The two crystal waters are stably present in the gypsum, and when they encounter high temperatures, the water can quickly diffuse into the air on the surface of the wall, thereby forming a "water film" on the surface of the wall material. The "water film" not only reduces the temperature of the surface of the wall material, but also acts as a barrier to oxygen to prevent and delay further burning of the wall material and the building, so the crystal water is Called "fire extinguishing water." The gypsum block is 66kg/m2 and contains about 13.86 kg of “extinguishing water”. The fire resistance limit is more than 3 hours.

2. Comfort: It refers to its "breathing function" and "warmness".

3. Fast: It means that the construction speed of the gypsum block is fast and the efficiency is high.

The construction of the gypsum block is a dry operation, and the block has a gutter and a shackle around the block, and the masonry speed is very fast. In addition, our company introduces high-precision German molds, the size of the products is more precise, and the walls built with it do not need to be plastered on both sides. Every day, each person can build more than 20 square meters, and the wall is built 24 hours later. Finishing is available. It is very convenient to install and hang items on the gypsum block wall, the construction efficiency is high, and the construction period can be greatly shortened.

4. Environmental protection: It means that the gypsum block does not pollute the environment in raw materials, production, construction, use and waste recycling.

(1) Low production energy consumption.

(2) Contains no harmful substances such as formaldehyde or radioactive elements.

(3) Recyclable: Only gypsum and water are used in the gypsum block formula. The discarded gypsum block can be used as a raw material for the production of gypsum building materials after being crushed and recalcined.

(4) Gypsum blocks produced from industrial by-product dihydrate gypsum discharged from industrial production are environmentally friendly and wasteful.

Third, the fly ash block

Fly ash brick is a new type of wall material. Its bulk density is one of its main technical indicators. Its weight is heavy and can be controlled according to the needs of the building and adjusting the process formula. The dry bulk density of fly ash bricks is between 1540 and 1640 kg/m3, which is slightly lighter than clay bricks (Clay bricks 1600 to 1800 kg/m3). Flexural Compressive Strength The flexural and compressive strength of fly ash bricks is determined mainly by the production process, formulation and hydration hydrothermal synthesis reaction and building needs. According to the building materials industry standard of the People's Republic of China (JC239-2001), the average flexural strength is between 2.5 and 6.2 MPa, and the compressive strength is between 10 and 30 MPa.

Features:

Regarding the thermal insulation performance of fly ash blocks, if air conditioning is installed indoors in the summer and the wall is facing unstable heat transfer, indoor insulation and insulation need to be considered separately. At this time, the indicators affecting heat insulation are mainly the temperature coefficient and the surface heat storage coefficient.

The fly ash block has a small temperature coefficient, which prevents the heat flow and temperature wave from passing through. The fly ash block maintains a small heat flow, a large attenuation factor and a long delay time compared with conventional materials. Under the same thickness conditions, the average temperature and fluctuation temperature of the inner surface of the fly ash block soil are small.

For summer insulation requirements, the benign effect of thermal conductivity is dominant, and the negative impact of surface heat storage coefficient is secondary. Therefore, as a result of the comprehensive effect, for buildings that do not use air conditioning to rely on natural cooling, the thermal insulation performance of fly ash blocks is still slightly better than that of traditional clay bricks and ordinary concrete.

4. Autoclaved lime sand brick

Autoclaved lime sand bricks are suitable for the interior and exterior walls of various civil, public and industrial plants, as well as the foundation of houses. It is a product that replaces sintered clay bricks. The autoclaved lime sand brick is formed by grinding and mixing with lime, quartz sand, sand or fine sandstone in an appropriate proportion, mixing with water, semi-dry pressing and autoclaving.

Features:

1. Frost resistance: refers to the ability of bricks to resist repeated freezing and thawing. If the autoclaved lime sand brick meets the product standard requirements according to the requirements, it can withstand the frost resistance test. The frost resistance of the autoclaved lime sand brick is related to its own strength, and the high strength has good frost resistance.

2. Water resistance: including the change of strength after dry and wet circulation and long-term soaking in water, the compressive strength of autoclaved lime sand bricks increased by dry-wet circulation or long-term in water.

3. Water absorption: Compared with sintered ordinary bricks, its water absorption speed is similar to that of sintered ordinary bricks.

4. Strength change under natural conditions: Autoclaved lime sand bricks are formed by reaction under high temperature and autoclave pressure. The hydration reaction is relatively sufficient, so it has stable strength and performance. In the atmosphere, the strength of the kettle is increased in the early stage, and it will not increase in the future and remain stable. When soaked in a humid environment and water for a long time, the strength will also increase.

5, high temperature resistance: autoclaved lime sand brick can not be heated for more than 200 ° C for a long time, below 200 ° C, the strength has basically no effect.

6. Chemical resistance: The immersion strength of lime sand bricks above MU15 does not change much in acid-base solution.

5. Autoclaved aerated concrete slab

The autoclaved aerated concrete slab is a lightweight and porous new green building material with cement, lime, silica sand as the main raw material and then added with different amount of anti-corrosion steel mesh according to structural requirements. It is autoclaved and steam-conditioned to produce autoclaved aerated concrete slabs with porous crystals. The density is smaller than that of general cementitious materials, and it has excellent performances such as fire resistance, fireproofing, sound insulation, heat insulation and heat preservation.

Features:

1. Economy: It can increase the use area, reduce the cost of foundations, shorten the construction period, reduce the cost of heating and air conditioning, and achieve energy-saving effects.

2, convenient construction: aerated concrete products are accurate in size and light in weight, which can greatly reduce human and material input. The dry construction method is often used in the installation of the plates, the process is simple and the efficiency is high, and the construction period can be effectively shortened.

3. Environmental protection: No pollution and hazardous waste are produced during the production process. When used, there is absolutely no radioactive material or harmful gas generated, even at high temperatures and in fire. Each individual microbubble gives the aerated concrete product a certain impermeability and prevents the penetration of water and gas.
