China's building insulation materials into the nano era

Not only was the Jinan Olympic Sports Center, the Beijing CCTV Building and the Shanghai Teachers' Apartment burned by the fire, but also the building materials market was affected by the fish. In mid-March, the Ministry of Public Security issued the "Circular on Further clarification of the Requirements concerning Fire Supervision and Management of External Thermal Insulation Materials for Civil Buildings". For a time, the discussion on the regulation and upgrading of the building insulation material market is in great demand.

A month has passed. Has this discussion affected the building materials market? Xiaobian visited the major building materials markets for this purpose. The result is an industry trend toward smaller developments. A building insulation material called Nano Coatings will become a replacement for traditional polyurethane materials and ceramic materials.

Nano coating monthly sales growth of 5 times It is reported that before the market's mainstream insulation materials for polyurethane exterior wall insulation materials, but it has a non-ideal insulation effect, safety conceivable congenital defects. In order to replace this material, companies have developed ceramic or glass insulation microbead coatings this year, which is indeed far better than the former in terms of heat insulation effect. “But the problem is appalling, because it has many layers of whitewash and uneven walls in practical applications.” According to industry insiders, because ceramic beads and glass insulation coatings contain larger diameter beads, they are in production. Brought about a lower cost issue.

The advantage of nano-coating is that this problem can be solved. According to a person in charge of a technology company, the average diameter of microspheres contained in nano-coating coatings is 2 micrometers, and the smallest or even nano-sized micro-beads are obviously smaller than 40-50 micron microbeads coated with ceramic microbeads. It will be very even, and naturally will solve the problem of large consumption and low cost performance.

On March 15, the Ministry of Public Security issued the “Circular on Further clarification of the Requirements for Fire Supervision and Management of External Thermal Insulation Materials for Civil Buildings”, which stipulates that civil buildings with external thermal insulation materials within the scope of fire engineering design review and fire acceptance of construction projects shall be The combustion performance of the external thermal insulation materials of buildings should be included in the review and acceptance, and the requirements for building insulation materials should be greatly improved. In the more than one month since then, the company’s sales of Thermoton Nano Coatings have grown significantly, five times more than in the previous month.

Nearly 54% energy saving

It is understood that although this nano-coating is a newcomer to the building materials market, there are no shortage of application cases. The zero-carbon museum of the World Expo and the experimental building of a real estate company are among them. In the building's outer wall, only a layer of heatton nano thermal insulation coating can achieve 53.38% energy-saving effect. This kind of energy conservation value is worth paying attention to, and it also fits with the concept of low-carbon construction, so in the future this kind of material will be widely used in our country's construction projects.

After using the new green building material, the Zero Carbon Pavilion can save 81% of heating energy consumption and 45% of electricity consumption compared with ordinary buildings. So Bill Dunster, the chief designer of the Zero Carbon Center in the UK, also stated that he will apply this material in his future zero-carbon projects. It is reported that nano-coating as a new type of building exterior insulation material has been used by many domestic construction companies. Whether such materials can bring about better flame-retardant and heat-insulating effects, we will wait and see.
