What is the difference between hard rock wool board and ordinary rock wool board?

People are no stranger to rock wool board. Rock wool board is a common insulation material with excellent thermal insulation effect and wide application. The rock wool insulation board is made of basalt and other ores as raw materials, which are processed through multiple processes after high temperature melting. The raw materials used for hard rock wool board and ordinary rock wool board are the same, but what is the difference between hard rock wool board and ordinary rock wool board? Let me introduce it briefly through the following text.

Compared with ordinary rock wool board, the production equipment of hard rock wool board is different. Generally speaking, the production equipment of rock wool board is divided into mechanism rock wool board production equipment and manual rock wool production equipment. The latter can be mass-produced in a few tens of thousands of yuan, but the production of hard rock wool board requires more than 100 million yuan of capital investment. The hard rock wool board has a very good sound insulation effect, which can isolate most of the noise outside the wall and become one of the best sound insulation materials in the construction field. Hard rock wool boards are widely used in many fields, such as electricity, metallurgy, textiles, national defense, etc., and are also used in boilers, flue, heat exchangers, fans and other equipment. With the development of the construction industry, due to its excellent thermal insulation, thermal insulation properties and flame retardant properties, hard rock wool panels are widely used in construction. With the advancement and development of science and technology, energy conservation and environmental protection have been valued all over the world. Hard rock wool board is a new type of energy saving and environmental protection material, which has been recognized and welcomed by people.

The hardness of hard rock wool board is much higher than that of ordinary rock wool board. An important indicator to determine the hardness of rock wool board is density. Therefore, the higher the density, the higher the hardness and quality of rock wool board. In summary, the quality of hard rock wool board is higher than the ordinary rock wool board.
