1. Precautions for transportation of rock wool thermal insulation products

1.1 During the transportation of rock wool, attention should be paid to waterproof, moisture-proof, sun exposure prevention, and ventilation;
1.2 Ensure that the interior of the transport vehicle is clean, free of debris, and dry; Vehicles that have transported asbestos products are not allowed to transport our products.

2.Precautions for storage of rock wool thermal insulation products

When storing rock wool on the construction site, it should be placed flat in a ventilated area, protected from water, snow, and moisture. The  stacking height should not exceed 2 meters, to avoid heavy pressure, sharp tool collisions, or punctures, to avoid damage to the insulation products.

3.Precautions before using and installing rock wool thermal insulation products

3.1 The coating of the equipment base layer has been completed and can enter the next process;
3.2 Necessary construction tools and labor protection articles shall be prepared completely;
3.3 Workers should wear various labor protection articles, protect occupational health, and pay attention to construction safety.
3.4 If working outdoors, please pay close attention to the weather conditions. Construction is prohibited in windy weather with force 5 or higher,   rainy days, and snowy days;
3.5 The rock wool products inspected on site have complete packaging, clear labels, and qualified quality assurance certifi

4.Precautions for use of rock wool thermal insulation products

4.1 Facilities and pipelines requiring thermal insulation should be free of leakage, dry surface, grease, and rust. In some conditions, in order to facilitate corrosion prevention, appropriate coatings can be applied.

4.2 In order to achieve the goal of minimizing heat loss, all joints of the plate and felt must be closely butted. When multi-layer insulation is used, staggered laying construction should be used to reasonably avoid cross joints to avoid the formation of thermal bridges. Cold bridges must be avoided during cold insulation.

4.3 Rock wool products should be coated with metal or plastic for outdoor thermal insulation or in areas prone to mechanical wear, and attention should be paid to the sealing of joints and seams. If necessary, plastic seals should be added, and the overlap of the wrapping layer should not be less than 100mm.

4.4 For cold insulation, it is necessary to add a moisture-proof layer on the cold insulation surface. When the temperature is particularly low, it is necessary to use resin-free rock wool for thermal insulation. The moisture-proof layer must also be fireproof.

4.5 When the temperature exceeds 200 ℃, appropriate external protection must be added to the insulation, so that the possible expansion will not change the thickness and unit weight.

4.6 For thermal insulation of large diameter or flat wall equipment using rock wool products, when the temperature exceeds 200 ℃, insulation nails should be added, and the outer protection (spacing 100-400mm) should be tightly attached.

4.7 When the insulation object is placed vertically and has a considerable height, its insulation layer must have positioning pins or support rings, with a spacing of not more than 3 meters, to prevent the insulation material from sliding downward when there is vibration.
