What is the sound insulation effect of 120kg rock wool roll felt insulation material?

In the field of industrial high temperature, the performance of insulation materials is directly related to production efficiency, energy loss, and operational safety. As the core insulation material in high temperature environments, the market price of industrial ceramic fiber blankets has always been a focus of attention for enterprise procurement. The current market price of industrial ceramic fiber blankets in China shows a clear hierarchical differentiation. 

How to calculate the price of insulation material rock wool blanket with different densities in aluminum factories? Aluminum plants operate under high temperature, vibration, and high dust conditions, and generally use hydrophobic, high-temperature rock wool blankets (GB/T 11835) with a higher density than ordinary buildings. The price calculation of rock wool blankets used in aluminum factories with different densities mainly follows one principle: the higher the density, the more raw materials are used, and the more expensive the price. Simply put, it's like buying a down comforter, the higher the filling amount, the higher the insulation effect and cost. Due to the fact that the factory unit of rock wool blankets is usually calculated in "tons", while actual construction and procurement are often settled in "cubic meters" or "square meters", corresponding unit conversions are required.

What are the installation steps for glass wool insulation materials in petroleum plant areas? In the petroleum plant area (petrochemical industry), the installation of glass wool insulation materials must strictly follow high standards for fire prevention, explosion prevention, corrosion prevention, and waterproofing. The glass wool insulation material used in the petroleum plant area is applied to the insulation of pipelines, tank walls, and tank ceilings, and the construction steps and precautions vary in different parts;
