New insulation sheet metal industry trend of diversification of a foregone conclusion

In recent years, the product structure of China's thermal insulation industry has undergone significant changes, emerging new types of insulation board material, cement foam calcium silicate insulation material proportion is growing year by year, rigid class thermal insulation products The proportion is declining. These new thermal insulation material performance will tend to diversify.

Lightweight material. In the same material, the smaller the density insulation material, the better the insulation effect.Cultured Stone Veneer In addition, the lightweight material will not increase the additional burden of the building envelope, reducing the possibility of leakage due to excessive structural loads.

Green materials. In recent years, fly ash, scrap foam?? Plastic waste has been widely applied in the field of thermal insulation. Degradation is difficult, and the high cost of processing waste and vigorously develop the resources to be effective, the environment is thus a significant improvement. Treatment and disposal of these wastes, the state has increased policy support, as raw material in the scrap foam insulation materials will have greater price advantage. In the production process to minimize the production of energy consumption and pollutant emissions, the development of plant fiber as the main raw material of green materials, will also be the development trend of the insulation material.

Super-efficient insulation. At present, the super-efficient insulation materials vacuum insulation materials and nano-porous materials two main points. Using the vacuum producing material or reduce the thickness of the solid portion of the material, even pore size limits the performance of the air convection and infrared ray at the nanoscale, they can be eliminated, reducing the occurrence of heat conduction and convection, to improve the thermal insulation effect.

Inorganic insulation materials (such as compound silicate insulation materials, etc.) research focus should be on reducing the energy consumption in the production process, to limit the emissions of dust and fiber, to reduce the amount of binder. Organic insulation materials (such as polystyrene foam insulation, polyurethane foam, etc.), research focus should be on finding a more suitable blowing agent to replace the F11; improved flame retardancy and reduce the cost of production of the material.

The development of multi-functional composite insulation materials to improve the efficiency of the insulation and expand the application surface.

Insulation materials used in applications there are varying degrees of impairment: calcium silicate in the presence of corrosive calcium oxide containing moisture status, easy, and retain moisture for a long time, not easy to use in low temperature environment; glass the fiber is easy to absorb moisture, is not suitable for a low-temperature environment, it is not suitable for the temperature environment of 540 ° C or above; mineral wool is the same there is a water-absorbent, should not be used in a low temperature environment and can only be used under high temperature environment without the presence of moisture; polyurethane foam and polystyrene vinyl foam should not be used in high temperature, flammable, contraction, resulting in gas; foam glass sensitive to thermal shock, not for drastic temperature changes state, so in order to overcome the lack of insulation materials, countries have developed lightweight multi-functional composite insulation materials.

Decoration effect, paving small floor joints more clutter and cramped, but the seams dirt intractable, easy to breed bacteria, so the large-size floor began to be popular in the market. But experts have warned that the larger the size the more easily deformed, and consumers should not blindly buy large-size floor.

Floor coverings is the highlight of the home decoration, choose what kind of flooring, paving, how acceptance, which is the decoration of the family concern. Recently discovered wooden floors became popular large-size, consumers are looking for quality. Today, large-size floor much to replace the small size of the potential of the floor. Due to the scarcity of material solid wood flooring, large-size composite floor had become the home decoration new favorite. But need to remind consumers that part of the floor is made ​​of inferior materials, so Xiaobian remind consumers to buy the floor vigilance "scrap" floor.

Purchasing wood floors this year, consumers value quality. Solid wood flooring is good, but the maintenance complex. This year, the supermarkets introduced a super wear-resistant solid wood flooring. It is said that this floor, in addition to a high wear resistance and the general characteristics of solid wood flooring, also have a strong film adhesion, high transparency, excellent acid and alkali resistance, moisture resistance, resistance to cracking, non-explosive paint .

Decoration effect, paving small floor joints more clutter and cramped, but the seams dirt intractable, easy to breed bacteria, so the large-size floor began to be popular in the market.

General Specifications of ordinary floor 12cm x 90cm, the specifications of large-size floor can reach 14cm × 180cm, the area is 2.3 times the ordinary wooden floor. It is understood that this floor is generally red sandalwood, rosewood and other common materials, get rid of the scrap, the main part of the production tree, highlight the atmosphere, the pavement up and have the unlimited sense an extension of the sense of space.

In addition to the ultra-wearable solid wood flooring, piano floor is the recent rise of mainstream products.Manufactured Stone Veneer Looks gorgeous, bright, ultra-generous wear layer, the visual effect is more bright, thorough, and foot feeling better, very much like the appearance of solid wood flooring, but the price is much lower than solid wood flooring.
