Rock Wool Products Energy Conservation

Improving building energy efficiency and achieving energy conservation and emission reduction are inevitable requirements for promoting sustainable social development. As a stable and widely used insulation material, rock wool play an important role in the field of energy conservation.

Rock wool insulation materials take natural rock as raw materials, after high-temperature melting, by high-speed centrifugal fiber, while adding a small amount of additives after high-temperature curing, made of different specifications of rock wool products. Rock wool materials in the production process will consume a certain amount of water, electricity, coke and other energy, JC/T522-2013 "People's Republic of China building materials industry standards - rock, slag cotton unit product energy consumption limit" requires that the unit output of rock wool products standard energy consumption must be less than 490kgce/t, data from the rock wool industry data show: The current domestic rock wool material unit output standard coal consumption is about 442kgce/t, the overall level is in line with the national energy consumption limit.

Rock wool materials consume a certain amount of energy in the production process, but they are used in the field of building insulation and industrial insulation, which can greatly reduce energy consumption during their life cycle and create considerable energy-saving benefits.

The latest official micro article of the domestic energy-saving professional media "Insulation Materials and Energy-saving Technology" takes the data on energy saving and carbon emission reduction of danish rock wool insulation system: when the heat transfer coefficient of the building wall is 0.42W/(㎡ ∙ k), the thickness of the rock wool material is about 80mm, and the weight of the 100 square meters of rock wool material is about one ton, which can save 32,800kg of standard coal and reduce carbon dioxide emissions by 108 tons in the 50-year service cycle, far exceeding its production energy consumption.

For more than 20 years, Huali has always insisted on transforming the earth's abundant rock resources into sustainable rock wool materials, reducing the energy consumption of the whole society, reducing the carbon footprint, and achieving the sustainable development of society.
