With the country's increasingly strict requirements on building material safety, environmental protection and energy saving, new building materials have begun to gain new opportunities for development. According to relevant data, the current annual demand for new building materials in China will reach at least millions of tons, which is several times the current annual output in China. According to the analysis of relevant experts, from the overall situation, promoting the use of new building materials will become one of the effective ways to reduce energy consumption and meet market demand in China.
At present, a multifunctional composite new building wall material often used in prefabricated buildings, microcrystalline foamed ceramic sheet, is grabbing most of the market share with its unique product advantages.
As a green, low-carbon and environmentally friendly new building material, microcrystalline foamed ceramic sheet is an environmentally friendly project of energy conservation, emission reduction, circular economy, and comprehensive utilization of solid waste that is strongly supported by the country. Its product performance meets the requirements of fire prevention, thermal insulation, environmental protection and energy saving advocated by the state. As a new material for waste, the raw materials for the production of this product are mainly bulk solid waste, which can use 70% ~ 85% of mining waste rock, tailings, coal gangue, fly ash and stone waste, saw mud, ceramic factory waste , Polishing mud and other solid waste.
Microcrystalline foamed ceramic sheet has unique product advantages, which are mainly reflected in the following aspects:
First, it is non-combustible. Microcrystalline foamed ceramic sheet belongs to non-combustible A11 class sheet with low thermal conductivity and is an ideal thermal insulation material.
The second is waterproof and moisture-proof. In the semi-open air and high temperature environment, it will not sink or deform. In the open air and high humidity areas, the wet expansion rate and dry shrinkage rate remain stable, and the waterproof and moisture-proof performance is excellent.
Third, the product has light weight, high strength, good toughness, high density, and good sound insulation, which can meet various types of sound insulation requirements of walls and barriers.
Fourth, the product has high strength, no deformation and warpage, and low weight, and is suitable for wall structure.
Fifth, it is easy to process and simple to construct, and it can be sawed, drilled, drilled, painted, and tiled.
Sixth, it is economical, beautiful, safe, and has a long service life. The product contains no other harmful substances and does not produce toxic fumes when burned. The product's ability to shrink, shrink, expand, and resist acid, alkali, and corrosion, and will not be damaged by moisture or insects. The strength and hardness increase with time, ensuring a long service life.
Seventh, it has excellent weather resistance, freeze-thaw resistance, sunlight resistance, rain resistance, and acid fog resistance.
Due to its unique product advantages, it has a very wide range of applications. This product is mostly used in building outer insulation, sound insulation, and wall masonry projects. Insulation composite boards, decorative boards and other occasions can replace wood boards and other places with high requirements on fire prevention, moisture resistance and environmental protection. In addition, microcrystalline foamed ceramic sheet is also widely used in office buildings, hotels, hospitals, factory buildings, schools, villas, theaters, playgrounds, subways, tunnels and other art buildings to make fireproof and waterproof materials and decoration. At the same time, microcrystalline foamed ceramic sheet can also be used in heat exchange materials, automobile exhaust devices, purification of molten metal in the metallurgical industry, heat recovery, industrial sewage treatment and thermal insulation materials.
The production process of microcrystalline foamed ceramic plate is stable and the production cost is low.
According to relevant investigations, the energy loss of houses and houses in China is about 50% of walls, 10% of roofs, 25% of doors and windows, and 15% of basements and the ground. However, China's building insulation materials, especially exterior wall insulation materials are still mainly organic materials, of which polystyrene market share is 90%, polyurethane is 10%. However, due to the material characteristics and fire prevention and management measures not being put in place, fire accidents often occur. Traditional building materials have been difficult to meet market demand. Microcrystalline foamed ceramic sheets have filled this market gap to a certain extent.
Relevant experts said that microcrystalline foamed ceramic plate as a new type of building material has the characteristics of low thermal conductivity, low water absorption, high strength, etc., and has more applicability and superiority in the field of building energy conservation. With the continuous improvement of the performance indicators of foamed ceramic insulation materials and the continuous improvement of standard specifications, microcrystalline foamed ceramic sheets will be promoted and used on a large scale and become the preferred product in the market.
