Product Description
Rock wool: English (rock wool)
Rock wool is also called rock cotton, is a kind of mineral wool. For natural rocks and minerals and other raw materials made of fluffy short fiber. Rock wool is a natural rock such as basalt, gabbro, dolomite, iron ore, bauxite, etc as the main raw material, made by high temperature melting, fibrosis and inorganic fiber.
The main purpose
Rock wool, mineral wool can be made into bars, belt, rope, mat, mat, mat, mat, pipe, plate. Used for single crystal furnace, metallurgical casting, petroleum cracking, and space technology, ablation resistance, high temperature resistant heat insulation materials; Buildings and equipment of the sound-absorbing material, the heat insulation materials; And natural asbestos substitute for cement products, rubber reinforcing materials and heat-sealed materials, high temperature filtration materials and high temperature catalyst carrier and so on
Basic performance
1. The thermal insulation performance: good heat insulation performance is the basic characteristic of the rock wool, mineral wool products, under the condition of normal temperature (25 ℃ or so) of their thermal conductivity is usually between 0.03 ~ 0.047 W/(moK).
2. The combustion performance: rock wool, mineral wool products of combustion performance depends on the amount of combustible dope. Rock wool, mineral wool itself belongs to the inorganic silicate fibre, nonflammable, in the process of processing into products, and sometimes to add organic binder or additives, the combustion performance of products can produce certain effect.
3. The sound insulation performance: rock wool, mineral wool products with excellent sound insulation and sound absorption performance, the sound absorption mechanism is this kind of products with porous structure, when the sound waves through the friction due to the effect of flow resistance, make part of the sound energy is absorbed by the fiber, hindered the sound wave transmission.
Rock wool, mineral wool) is a kind of natural mineral, non-toxic harmless green products, hereinafter referred to as mineral wool. Its fire prevention performance is good, good durability, can do it with life synchronization structure, small volume density, low thermal conductivity, sound-absorbing performance is good, not burning, heat resistance, frost resistance, corrosion resistance, not afraid to eat by moth, good chemical stability and other characteristics are widely used in construction and industrial equipment, pipelines, adiabatic, fire prevention, sound absorption of kiln. But make it mat, carpet, cushion, rope, boards, etc.
In recent years, in the field of building energy-saving material, as has become the hot spot in the building materials industry, mineral wool industry application in the field of building energy efficiency, enabling it to the new development opportunity, enterprise more competitive, increased product technology content, function more hasten is novel, with enterprises as the main body of the industrial structure adjustment has entered a new stage. Therefore, mineral wool industry has become a green, environmental protection industry a new growth point of adiabatic insulation materials. [1], mineral wool industry in China is facing huge opportunities for development, now no more than the average person in mineral cotton geo-hazards ownership is only a small percentage of a fraction of the developed countries. In quite a long period of time, our country industry with thermal efficiency is low, the current situation of pollution of heavy coal as fuel will not change, major cities in our country is the world the same latitude low winter temperatures average 2 ~ 3 ℃, the summer climate 5 ~ 15 ℃. Have more reason to need to heat preservation and heat insulation. Along with our country national economy continues to develop, to make the transition to middle-income countries, the increasing focus on energy saving, environmental protection, to the pursuit of better comfortable, healthy, low energy consumption building, one of the main insulation sound-absorbing material of mineral wool materials, will usher in rapid development period.
