In the selection of materials and the construction process of decoration, some friends can’t tell the difference between mineral wool board and rock wool board. What is the difference and the different role? They are different from production raw materials, application characteristics and usage scenarios.
Leading them in the production of different raw materials, rock wool board basalt, diabase and other ores are the main raw materials. After high temperature melting, the inorganic fiber board processed by high temperature melting is usually called rock wool insulation board; mineral wool board is made of inorganic fiber board. The ceiling is mainly made of high-quality mineral wool as the base material for decoration, also called mineral wool sound-absorbing ceiling. Secondly, because the raw materials are not the same, the characteristics and applications are different. The biggest feature of mineral wool board is that it has good sound absorption and heat insulation effect. Because its raw material is ultra-fine mineral wool fiber, it has abundant tiny voids, which can effectively absorb sound waves and reduce sound wave reflection. It can control and adjust the reverberation time, improve indoor sound quality and reduce indoor noise. Mineral wool board has colorful patterns and embossed shapes, and has a good decorative effect. It has good thermal insulation performance and low thermal conductivity, and is a good thermal insulation material. Mineral wool ceilings are mainly used in conference halls, libraries, concert halls, high-end hotels, gymnasiums, hospitals, office buildings, production workshops and other places with sound absorption requirements. Because mineral wool is an inorganic material, it will not burn. It is very low, so the mineral wool board can meet the requirements of non-combustible B1 level. Rock wool board is mainly composed of inorganic fibers such as rocks to form a porous connection structure, which determines that rock wool board is a fire-proof, flame-proof, heat-insulating, and sound-absorbing material. The chemical properties of rock wool are stable, the pH value is 7-8, neutral or weakly alkaline, and metal materials such as carbon steel, stainless steel, and aluminum are not corroded. Therefore, rock wool board is mostly used for thermal insulation of external walls of industrial buildings. Mineral wool board and rock wool board are two completely different materials in terms of decorative effect. They have great differences and applications. We should distinguish these two materials in use to avoid making jokes.
