When it comes to the hero of the story, it can be traced back to the first volcanic eruption on the island of Hawaii. When everything around the island returned to calm, the residents of the island inadvertently found a strand of soft rock after melting on the ground. At that time, people were very surprised at what happened, so they gave it a beautiful name, "Phal's hair". And these soft rocks are the first known rockwool fibers.

Characteristics of rock wool

Fire prevention

The use of natural volcanic rocks, non-combustible building materials fireproof materials.

☉ has the highest fire rating A1, which can effectively prevent the spread of fire

The dimensions are very stable and do not extend, contract or deform in a fire

☉ High temperature resistance, melting point above 1000℃

☉ Do not produce smoke or burn droplets/debris in a fire

☉ Substances and gases harmful to the environment are not released in a fire

Heat preservation and insulation

Rock wool fiber slender and flexible, low slag ball content because the product contains a lot of air, can effectively prevent heat transfer, so the thermal conductivity is quite low, is a high-quality thermal insulation material sound absorption noise reduction rock wool is an ideal sound insulation material, a large number of slender fibers formed a porous connection structure, determine rock wool is an excellent sound absorption noise reduction material.

waterproof

Hydrophobic rock wool product hydrophobic rate can reach 99.9%☉ water absorption rate is very low, no capillary penetration. Excellent resistance to moisture

In the environment of large relative humidity, the volume moisture absorption rate of rock wool is less than 0.2%

non-corrosive

The chemical properties of rock wool are stable, PH value is 7-8, neutral or weakly alkaline, and there is no corrosion to carbon steel, stainless steel, aluminum and other metal materials.

Safety and environmental protection

Test does not contain asbestos, CFC, HFC, HCFC and other harmful substances to the environment ☉ to the human body non-toxic, harmless, not easy to breed bacteria and insects, do not pollute the environment. (Rockwool has been recognized as non-carcinogenic by the International Cancer Research authority)

Convenient energy saving

The product construction, installation is convenient, energy saving effect is remarkable, with a high cost performance, mineral cotton fiber leaching solution PH value is close to neutral, good compatibility with metal and organic materials, not easy to corrosion and other adverse reactions

☉ Fluffy short fine fibers made from mineral raw materials. It has the properties of non-flammable, non-mildew and non-decay

Since 2009, the application of rock wool in the field of construction has been rapid development, the annual production capacity continues to increase, and the quality of its products has also been greatly improved. As a new type of insulation material, the application in the field of industrial insulation is also very extensive. With the development of the shipbuilding industry, composite rock wool board cabin material as a new type of non-combustible cabin material has been widely used by the shipbuilding industry at home and abroad

With the continuous development of agricultural facilities and the popularization of greenhouse facilities in our country, rockwool has been widely used in the field of agriculture. At present, our country has become one of the largest countries in the development speed of facility agriculture and the existing greenhouse area

Therefore, rock wool is not only playing a growing role in the construction industry, but also plays a pivotal role in other industries. There is still a lot of room for appreciation, and it will get more and more attention in all walks of life.

The difference between high-quality rock wool and slag rock wool is mineral wool, and there are many common points between them in terms of production technology, fiber form, alkali resistance, thermal conductivity, non-flammability and so on. People usually refer to rock wool and slag wool as mineral wool, so it is easy to see the two as the same thing, which is a misunderstanding. Although they are all mineral wool, there are also some differences that cannot be ignored. The main reason for these differences is the difference in raw material composition. In China, the main raw material of slag wool is generally blast furnace slag or other metallurgical slag, and the main raw material of rock wool is basalt or diabase, and their chemical composition is quite different. Rock wool is better than mineral wool in the following aspects:

Rockwool has high acidity coefficient, its chemical stability, high temperature resistance, corrosion resistance and so on are better than slag wool.
