Nowadays, there are all kinds of thermal insulation materials in the modern construction industry. How many people know what insulation materials are and the external wall waterproof rock wool board is the theme of this time. The waterproof rock wool board is a new type of tubular insulation material. Basalt and other natural minerals are the main raw materials, which are melted at high temperature to form a tubular insulating material by melting into fibers, adding a suitable amount of binder, and curing. Rock wool insulation pipe has the advantages of low thermal conductivity, high operating temperature, non-flammable fire protection, convenient construction and high cost performance. It is used by modern people for insulation, energy saving and frost protection in various pipes. So, what are the functions of the outer wall waterproof rock wool board ? What are the precautions for waterproof rock wool board?

Exterior waterproof rock wool board effect

First, waterproof rock wool board is used for a wide range of applications in construction, petroleum, electric power, metallurgy, textile, defense, transportation and other industries, but also pipeline storage tanks, boilers, flue, heat exchangers, fans, trucks, etc. Industrial equipment is the ideal material for heat insulation and sound insulation.

Second, waterproof rock wool board is suitable for industrial equipment, construction, ship thermal insulation, sound insulation, etc., is widely used in modern oil, chemical, metallurgy, boat parking, textile and other industrial boiler and equipment pipe insulation, also commonly used The insulation and sound absorption of the partition walls, ceilings and internal and external walls of the construction industry are also used for fire prevention and noise reduction of building partitions, firewalls, fire doors and elevator shafts.

Third, waterproof rock wool board is generally used in planes and larger radius of curvature tanks, boilers, large steel structures, glass curtain wall insulation and other fields. Waterproof rock wool board is affixed with aluminum foil to meet the needs of heat insulation and vapor barrier for HVAC ducts, cold and warm water pipes as well as building insulation requirements, so that the indoor cool in winter and cool in summer and comfortable in four seasons.

4. Water-repellent additives have been added to marine rock wool board and hydrophobic rock wool board, which have good moisture-proof performance. Shipboard waterproof rock wool board is generally used for ship thermal insulation and fireproof partitions; drowning rock wool boards are mostly used for vehicles, mobile equipment, cold storage projects, air conditioning pipes, and thermal insulation and fire protection in wet environments and some moisture-proof requirements Application occasions.

Waterproof rock wool board features

1, waterproof rock wool board product appearance surface is relatively flat, the surface without any obstacles to prevent practical damage, stain damage.

2, waterproof rock wool board is an inorganic material, is a natural product from the natural, non-toxic harmless green products.

3, waterproof rock wool board is non-combustible items, fire resistance is good, its heat load shrinkage temperature of 643 degrees, moisture absorption of 3.9%, organic matter content of 2.9%.

4, waterproof rock wool board has a very good moisture, fire, thermal insulation, sound absorption and mechanical properties.

5, waterproof rock wool board durability, can be synchronized with the structure of life, while meeting the thermal insulation performance while also has a certain degree of sound insulation.

6. Waterproof rock wool board has high acidity coefficient, better chemical stability and fiber durability.

Waterproof rock wool board notes

1. Pay attention to rain protection and do not construct it on rainy days.

2. For cold insulation, it is necessary to add moisture-proof layer, under conditions of exceptionally low temperature, thermal insulation with resin-free rock wool, and its moisture-proof layer must also be fire-proof.

3. When the temperature exceeds a certain temperature, such as: 200 °C, insulation must be added to the appropriate external protection, so that the rock wool board thickness and bulk density will not change.

4. For the insulation of large-diameter and flat-walled equipment with rockwool products, if it exceeds 200°C, it is important to keep in mind that the rock wool board manufacturer's 叮嘱: plus insulation nails, (with a spacing of around 400mm) must be tightly attached.

5. The equipment, insulation nails, and pipes that need to be insulated are conducive to anti-corrosion and can receive appropriate coatings. In addition, there should be no leaks. This can achieve better results.

6. The rock wool board finished product is susceptible to mechanical wear under the condition of outdoor heat preservation. It should be covered with metal or plastic cover, then pay attention to the place of the joint, seal the joints, add glue seal when needed, and the wrap layer partial is not less than 100mm.

7. When the insulation object is placed at 90 degrees, and there is a certain height, the insulation layer of the rock wool board must have a positioning pin or support ring, the spacing must not be greater than 3 meters, to prevent the insulation material to slide down when there is vibration .

8. In order to achieve the minimum goal of heat loss, the joints of rock wool board and felt must be tightly connected. If there are multiple layers of heat insulation, each cross joint needs to be intertwined so as to avoid forming a thermal bridge. When cooling, it is necessary to eradicate the cold bridge. .

Editor's summary: The above is about the role of external wall waterproof rock wool board. It is for reference only and hopefully it will help everyone. If you want to know more related information, you can pay attention to this website information.
