  • Detail

Nowadays, there are all kinds of thermal insulation materials in the modern construction industry. How many people know what the thermal insulation material is. The theme of this time is the waterproof rock wool board of the outer wall. The waterproof rock wool board is a new type of tubular thermal insulation material, which is mainly made of basalt and other natural ores, which are fused into fibers at high temperature, added with an appropriate amount of binder, and cured. Rock wool insulation pipe has the advantages of low thermal conductivity, high service temperature, fire prevention and non combustion, convenient construction and high performance price ratio. It is used by modern people for heat preservation, energy saving and antifreeze of various pipelines. Then, what are the functions of waterproof rock wool board of exterior wall? What are the precautions for waterproof rock wool board

nowadays, there are all kinds of thermal insulation materials in the modern construction industry. How many people know what the thermal insulation material is. The theme of this time is the waterproof rock wool board of the outer wall. The waterproof rock wool board is a new type of tubular thermal insulation material, which is mainly made of basalt and other natural ores, which are fused into fibers at high temperature, added with an appropriate amount of binder, cured and processed. Rock wool insulation pipe has the advantages of low thermal conductivity, high service temperature, fire prevention and non combustion, convenient construction and high performance price ratio. It is used by modern people for heat preservation, energy saving and antifreeze of various pipelines. Then, what are the functions of waterproof rock wool board of exterior wall? What are the precautions for waterproof rock wool board

the function of waterproof rock wool board on the outer wall

first, waterproof rock wool board is widely used. It is suitable for many industries such as construction, petroleum, electric power, metallurgy, textile, national defense, transportation and so on. It is also an ideal material for thermal insulation and sound insulation of industrial equipment such as pipeline storage tanks, boilers, flues, heat exchangers, fans, vehicles and ships

II. Waterproof rock wool board is applicable to the thermal insulation and sound insulation of industrial equipment, buildings, ships, etc. in modern times, it is widely used in the thermal insulation of various industrial boilers and equipment pipelines such as petroleum, chemical industry, metallurgy, shipping, textile, etc. it is also commonly used in the thermal insulation and sound absorption of partition walls, ceilings, internal and external walls in the construction industry, as well as the fire prevention and noise reduction of building partition walls, firewalls, fire doors and elevator shafts

III. waterproof rock wool board is generally used in tanks with large plane and radius of curvature, boilers, large steel structures, external insulation of glass curtain walls and other fields. The waterproof rock wool board pasted with aluminum foil can meet the needs of HVAC air duct, cold and warm water pipe insulation and water vapor barrier, as well as the needs of building insulation, making the indoor warm in winter and cool in summer, and comfortable in four seasons

IV. marine waterproof rock wool board and hydrophobic rock wool board are added with hydrophobic additives, which have good moisture-proof performance. Marine waterproof rock wool board is generally used for thermal insulation and fire partition of ships; Hydrophobic rock wool board is mostly used in vehicles, mobile equipment, cold storage engineering, air conditioning pipelines, thermal insulation and fire prevention in humid environment and some applications with certain moisture-proof requirements

characteristics of waterproof rock wool board

1. The appearance surface of waterproof rock wool board products is relatively flat, and the surface is free of any scars, stains and damages that hinder practical use

2. Waterproof rock wool board is an inorganic material, which is a non-toxic and harmless green product from natural minerals

3. Waterproof rock wool board is a non combustible material with good fire resistance. Its heat load shrinkage temperature is 643 degrees, moisture absorption is 3.9%, and organic content is 2.9%

4. Waterproof rock wool board has excellent moisture-proof, fire-proof, heat preservation, sound absorption and mechanical properties

5. The waterproof rock wool board has good durability, can synchronize with the structural life, and has certain sound insulation effect while meeting the thermal insulation performance

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

precautions for waterproof rock wool board

1 Pay attention to rain prevention, and do not construct in rainy days

2. For cold insulation, it is necessary to add a moisture-proof layer. Under the condition of extremely low temperature, rock wool without resin is used for heat insulation, and its moisture-proof layer must also be fireproof

3 When the temperature exceeds a certain temperature, such as 200 ℃, appropriate external protection must be added to the insulation, so that the thickness and unit weight of rock wool board will not change

4. For the insulation of finished rock wool products for large-diameter and flat wall equipment, when the temperature exceeds 200 ℃, we must keep in mind the instructions of the rock wool board manufacturer: add insulation nails (with a spacing of about 400mm) and stick the outer protection tightly

5. Equipment, insulation nails and pipelines that need insulation can receive appropriate coating for corrosion prevention. In addition, there should be no leakage. This can achieve better results

6. If the finished rock wool board is vulnerable to mechanical wear under the condition of outdoor thermal insulation, it should be wrapped with metal or plastic, and then pay attention to the joints and the sealing of joints. If necessary, add glue seals, and the stacking part of the wrapping layer should not be less than 100mm

7 When the insulation object is placed at 90 degrees and has a certain height, the insulation layer of rock wool board must have locating pins or support rings, and the spacing must not be greater than 3 meters, so as to prevent the insulation data from sliding downward in case of vibration

8. In order to minimize the heat loss, the joints of rock wool board and felt must be closely connected. If there are multiple layers of insulation, the cross joints need to be intertwined to avoid forming a thermal bridge, and the cold bridge must be eliminated during cold insulation

editor's summary: the above information is about the function of waterproof rock wool board of exterior wall, which is for reference only. I hope it will be helpful to you. If you want to know more about it, you can pay attention to the information
