What new wall materials are there?

With the development of society and times, the birth of new wall materials enables us to save materials better. By using new materials, we can make full use of waste and then turn it into resources, which not only saves money greatly, but also protects the environment and saves resources, mainly in the field of construction. Do you know what a new wall material is? Then the following types introduce the main types of new premise materials in detail, please read on.

Introduce all kinds of new building energy-saving materials

1, a new wall material

In terms of varieties, new wall materials include bricks and boards. , such as clay hollow bricks, non-clay bricks, building blocks and aerated concrete, lightweight composite boards, etc.

2, thermal insulation materials

Both thermal insulation materials and thermal insulation materials belong to thermal insulation materials. Commonly used thermal insulation materials mainly include mineral wool and glass wool, foamed plastics and porous polymers, and various composite thermal insulation materials.

Application:

(1) is mainly used for thermal insulation of walls and roofs in the building field;

(2) The application is insulated from thermal equipment and thermal pipeline.

(3) Cold storage and cold storage rooms are also used.

3, waterproof sealing material

Waterproof material is also an important functional material in the construction industry and an important part of the building materials industry. With the development, higher requirements are put forward for the quality and performance of waterproof sealing materials.

4. Energy-saving glass

The energy saving of doors, windows and glass accounts for more than 40% of buildings, and also plays a decisive role.

5, solar energy utilization

Solar energy is the most abundant and ideal energy we use, and making full use of solar energy is also a good way to protect and save materials.

China's wall materials are far behind developed countries in terms of product composition, overall technical level, product quality and use function. For a long time, small solid clay bricks have occupied an "absolute dominant" position in the product composition of wall materials in China, and China is known as the "kingdom" of small solid clay bricks in the world. In view of the problems existing in the production and use of small solid clay bricks, such as large land destruction, high energy consumption and serious environmental pollution, China must vigorously develop and popularize soil and water conservation. Energy-saving, turning waste into treasure, multi-functional, environmentally friendly and in line with the requirements of sustainable development, many of these wall materials have been produced and used in developed countries for forty or fifty years or even longer, such as gypsum board, concrete hollow brick, etc., but combined with the current situation of wall materials in China, compared with traditional small solid clay bricks, they are still relatively unfamiliar to most people in China, so they are collectively called new wall materials.

With the development of wall reconstruction, the above standards will be gradually improved. The new wall materials are mainly silicate materials such as concrete, cement and sand, and some are made into non-clay bricks, blocks and building plates by pressing or sintering, steam curing, autoclaving and other processes, adding some industrial wastes such as fly ash, coal gangue and slag or construction waste. New wall materials generally have a series of advantages, such as heat preservation, heat insulation, light weight, high strength, soil saving, energy saving, waste utilization, environmental protection, improving building functions, increasing the use area of houses and so on, and a considerable part of them belong to green building materials. Some new wall materials are supplemented by certain air interlayer, which not only reduces the bulk density, but also greatly improves the thermal insulation performance. Sintered hollow bricks have better thermal insulation function than solid products.

What are the contents of the new wall materials sorted out above? Do you have a general understanding of new wall materials? The main types of new wall materials are analyzed in detail above. In the selection of engineering materials, we should investigate the actual situation and choose according to the amount available for consumption. For different wall materials, the application scope is limited. The suggestion here is to choose the core wall material with strong universality, which can greatly improve the work efficiency in the project.
