talking about the development prospect of special rockwool b-k8凯发

because rock wool does not contain toxic and harmful substances, it will not release gases that are harmful or harmful to the environment and human body even under high temperature conditions. in terms of waterproofing, the rock wool has strong water repellency and low water vapor permeability resistance, which can effectively reduce the mildew of the building wall. in terms of thermal insulation, rock wool has a small thermal conductivity and good thermal insulation properties. in terms of sound absorption, rock wool is a porous fibrous material. when the sound passes, the vibration and mutual friction of the fiber consume sound energy and play the role of sound absorption. in terms of stability, the rock wool has high stability, the thermal conductivity does not change with time, and the expansion ratio is low. it does not cause additional stress on the surface of the mesh cloth, mortar, etc. due to thermal expansion and contraction; at the same time, the rock wool does not contain active elements. with corrosive ingredients, it also does not contain solvents, oily substances or softeners that affect the building. it is not easy to age and can last the same life as the main building. in terms of mechanical properties, after the improvement of the production process, rock wool has good compressive strength and tensile strength on the one hand, and easy construction on the other hand. it can be cut at the construction site with a simple cutting tool. into the shape you need.

as a material for external thermal insulation materials, rock wool has been widely used in developed countries in europe and america, and related technologies and standards have matured. however, in china, rock wool is mainly used in the field of industrial insulation, and there are not many applications in the field of building insulation. the form is limited to filled insulation, and the development of external insulation is not enough. however, with the introduction of relevant documents, materials for exterior insulation the level of combustion performance is highlighted. in particular, civil buildings should adopt the requirements of materials with a burning performance of class a. it provides opportunities for the extensive use of materials such as rock wool with outstanding fire performance in the field of exterior insulation.
