Several major barriers to the development of new building materials

The difficulties encountered in the development of the new building materials industry, new energy-saving building materials include new wall materials, chemical building materials, new thermal insulation materials, architectural decoration materials. Although there are market demands, in fact, due to cost and market restrictions and technical barriers, the development of new energy-saving building materials is currently struggling.

In fact, people's choice of building materials directly affects the development of energy-saving building materials. At present, in the interior decoration, due to the lack of awareness of energy saving and environmental protection, many owners are not willing to spend money to use new energy-saving and environmentally-friendly building materials. As a result, the content of formaldehyde in the room after renovation is excessive, which not only endangers the health of the owners but also causes economic losses. Huge material waste.

Although new energy-saving building materials have the advantages of high technology content, low resource consumption, long service life, and less environmental pollution, the use cost is not as high as that of general building materials. However, in terms of market prices, it does not have a competitive advantage. The high production cost of energy-saving building materials makes it difficult to lower the selling price of these new products and it is difficult to become the darling of the market. For example, the new insulation material polyurethane foam, the current share of the use of external wall insulation accounted for less than 10%. Only a few large-scale real estate development companies that focus on brand building use polyurethane rigid foam exterior wall insulation systems.

At this stage, the competition of most of China's new building materials companies is concentrated on medium and low-end products. Products with higher technological content are relatively few, and competition in high-end fields is not fierce. The most obvious is the plastic pipe and window and door industry. At present, the production of low-end products in the country has experienced excess capacity and the market growth has slowed down. Domestic plastic pipe and pipe fittings are mostly general-purpose products. The use of pipe and fittings with high requirements and high added-value has produced less, which has greatly limited its market application. The application of high-end plastic pipe materials is only at the initial stage. The main reason is that the industry lacks investment in science and technology in terms of energy conservation and resources, and the lack of technological innovation has affected the overall level of the industry. The PC transparent board market favored by the market, due to high technical requirements, domestic enterprises can not achieve a breakthrough in technology, most of the market position is occupied by foreign companies.

At present, in the production and sales of high-profit-making wall internal and external thermal insulation panels, roof waterproof materials, and other types of plastic building materials, there are short-sighted behaviors that produce instant benefits and quick successes, laying a hidden danger for the development of the industry. In addition, building energy-saving materials such as cement hollow bricks replacing clay solid bricks and clay hollow bricks have been widely promoted, but such products also have problems such as insufficient strength and large construction differences that affect the quality of the works.

In addition to the above-mentioned two major bottlenecks, related incentives and supporting policies are not perfect, the building materials industry itself has low barriers to entry, low concentration, and disorderly market competition, and companies are facing pressure to transfer to high-tech and high-end markets. All of these are important reasons why new energy-saving building materials are difficult to develop rapidly in a short period of time. They also grasp the important development pulse and continue to develop and upgrade.
