Rock wool board has Class A fire protection, thermal insulation and other characteristics, is designed for building exterior wall insulation thin plastering system design, rock wool, slag wool at normal temperature (around 25 °C) thermal conductivity is usually 0.036 ~ Between 0.041W/(m·K), it is an inorganic silicate fiber and non-flammable. The external wall insulation should be organically integrated into the four departments of architecture science, materials science, fire science and environmental science.
Fire is something that people do not want to see, and in the external wall insulation system, absolutely cannot miss one another. When using stone wool insulation board, we must ensure that the effect of heat preservation is also accompanied by whether the fire protection performance meets the standard. In addition, we must also be able to help save energy while preventing fire. We must not be afraid of fire because we are very concerned about fire prevention. However, it ignores the important principle of energy saving.
Inorganic insulation material is represented by rock wool. It is suitable for exterior wall insulation or energy-saving renovation of newly built or existing buildings with dense structures such as concrete or brick walls. It can also be used as a wall insulation fireproof belt, and it can be used in combination with insulation materials whose combustion performance cannot reach class A. In order to improve the fire protection function of the external walls of buildings. Any study that deviates from the four universities has relative one-sidedness and limitations. Doing a good job of fire protection for external wall insulation needs to do the following: 1. Choose a good insulation material; 2. Strictly enforce all kinds of fire regulations and fire control systems; 3. To monitor the construction process in the middle stage of the use of insulation materials to prevent the occurrence of various fires; 4. Use fire protection measures in the initial stage of the use of insulation materials; 5. After the insulation material is made into the external wall insulation system, the insulation system is used properly to prevent and prevent the occurrence of fire.
It is not enough to rely solely on the fire resistance of thermal insulation materials such as rock wool insulation boards to prevent the occurrence of fire. The fire prevention problems of external wall insulation also require the integration of various factors.

Phoxim insecticidal spectrum is wide and knocked out power, give priority to with tag and stomach poison effect, no inner absorption effect, is effective for lepidoptera larvae. In the field because of the light is not stable, quickly decompose, so residual period is short, the residual risk is small, but the drug in the grave, residual period is long, suitable for the prevention and control of underground pests. Dosage form, 50% and 45% phoxim ec, 50% granules.
