Vertical filament rock wool composite panels have broad market application prospects

2021-12-01

Compared with the organic insulation system in the energy-saving market, the biggest advantage of the rock wool board insulation system is the fire safety of the system. This is because rock wool, as an ideal Class A insulation material, has the advantages of non-combustibility, breathability, sound absorption, and high thermal stability. In addition, compared with Class A insulation materials such as foamed cement insulation boards, expanded perlite boards, and vitrified microbeads, rock wool insulation boards have smaller thermal conductivity and excellent thermal insulation properties. Under normal temperature conditions (around 25°C) The thermal conductivity of rock wool is usually between 0.036W/(m·K) and 0.040W/(m·K). But at the same time, there are also obvious shortcomings in the rock wool board insulation system, especially the rock wool board thin plaster insulation system, whether it is a rock wool board double-layer alkali-resistant fiberglass mesh structural system or a single-layer rock wool board alkali-resistant The fiberglass mesh structural system has exposed many problems in engineering applications in recent years. There have been many accidents of the rock wool thin plaster insulation system falling off. The main reasons are:

What role does rock wool composite board play in the construction industry?

2021-06-21

Rock wool composite board is mainly made of iron ore and basalt. Its hardness is stronger than rock wool board. Rock wool composite board has a smooth appearance, no trace of damage, and is resistant to high temperatures of 800 degrees. After repeated fine processing, it has excellent overall performance and Has strong impact resistance. It is difficult to cut it with scissors. It also has excellent thermal insulation properties. If you want to insulate some factories or important equipment, please consider using rock wool composite panels.

For exterior wall insulation, you can choose composite rock wool boards to save time, effort and worry.

Nowadays, some building exterior walls use composite rock wool boards, so why are composite rock wool boards used as exterior wall materials? Let’s take a look.

Common problems and reasons for polyurethane spraying construction

2021-03-11

Polyurethane spraying is high-pressure polyurethane spraying equipment. Because the materials of the high-pressure spray equipment collide at high speed and rotate violently in the small mixing chamber, the mixing is very thorough. The high-speed moving material forms fine mist-like droplets at the nozzle of the spray gun and is evenly sprayed onto the surface of the object. Foamed polyurethane spray coating is mainly used for thermal insulation and sealing in thermal insulation and refrigeration. For coating of thermal insulation materials that are difficult to use with molds, such as large spherical storage tanks, large-diameter special-shaped pipe fittings, cold storage walls, etc., on-site foaming can be achieved.
