Introduction of insulation data selection
In addition to the thermal conductivity of the data, the water absorption, incineration function and intensity of the data should also be taken into account. The functional characteristics of different adiabatic data can be seen in the corresponding classification guide.
Inorganic insulation data are generally used to guide data that the thermal coefficient is less than or equal to 0.2.
The selection of excellent insulation skills and materials in construction and industry can often achieve twice the result with half the effort. The calculation indicates that every ton of mineral wool insulation used in the construction can save a ton of oil a year. The selection of energy saving residential areas in Beijing indicates that the coal saving rate per unit area is 11.91 kilograms per year of standard coal / m2. The insulation of industrial equipments and pipes and the selection of excellent insulation measures and materials can obviously reduce the energy consumption and cost of production, improve the environment and have better economic benefits. For example, in industrial equipment and pipeline engineering, outstanding thermal insulation conditions can reduce heat loss by about 95%. Generally, the investment for thermal insulation materials can be recovered by saving energy in about a year.
Classification of incineration functions for data and decoration materials
The burning function of building materials refers to all the physical and chemical changes that occur when they are burned or caught in fire. This function is measured by the ignition and flame transmission, fever, smoke, carbonization, weightlessness and the occurrence of toxic products. The burning function of the national standard GB8624-97 will be divided into the following grades.
Class A: incombustible construction materials: there is no inion about incineration.
Class B1: inflammable material: inflammable materials have good flame retardancy. When it meets open fire in the air or under the action of high temperature, it is difficult to ignite, and it is not easy to break out and extend quickly, and when the fire source is removed, the burning stops imtely.
Class B2: combustible materials: inflammable materials have certain flame retardancy. When exposed to open fire in the air or under the action of high temperature, it will burn imtely, which easily leads to the extension of fire, such as wooden columns, wooden roof trusses, wooden beams, wooden staircases and so on.
Class B3: inflammable material: no flame retardant, easy to incinerate, and highly dangerous.
Correct application of inion on different incineration grades
Building materials used in buildings should meet the requirements of national mandatory standards, which is GB50222-95 Fire Protection Standard for Building Interior Decoration Design. In the standard, it is required that "the construction interior decoration design should properly handle the opposition between decoration function and application safety, actively select non-combustible and non-combustible materials, and try to prevent them as far as possible." Choose the inion of smoke or poisonous gases that occur during incineration, so as to be safe and applicable, advanced in skills and reasonable in economy. Therefore, when choosing construction materials or interior decoration materials, customers should give priority to non-flammable A-grade and non-flammable B1-grade products in order to protect their own safety.
