Things to note when spraying inorganic fiber cotton for thermal insulation

The thermal insulation and sound-absorbing layer sprayed with inorganic fibers should provide a ventilated and dry environment. Usually at an average temperature of 25°C and a relative humidity of ≤60%, the drying and curing time is 24 to 72 hours depending on the thickness. After that, other processes such as decoration can be carried out. .

Before inorganic fiber spraying, various pipelines, air ducts and other equipment hanging parts should be installed to avoid drilling and chiseling on the base surface after spraying is completed.

During the drying and curing period, inorganic spray-coated finished products must be protected from mechanical collision and rainwater erosion.

When the inorganic spray coating is partially damaged due to collision, it should be repaired locally; for parts that are often susceptible to mechanical collision, glass fiber cloth or other protective materials can be applied to protect the surface of the fiber layer.

Keep the environment in the spraying area clean to avoid flying dust and contaminating the surface of the finished spray coating. During the spraying construction process, spraying operators should wear dust masks in accordance with the relevant provisions of the national labor protection regulations, and high-altitude operators should wear safety belts and other protective equipment.

1. Underground garages, underground protective spaces, tunnels, culverts, special passage corridors, ships, cold storage, etc.

Regarding fire prevention measures (mainly based on actual reports), many developed countries have implemented mandatory regulations such as new construction projects needing to meet standards and existing spaces need to be renovated, otherwise construction or use will be suspended. Our country's "inorganic fiber spraying technology system" for the construction and use of this type of space is the key method for this just right.

2. Inorganic fiber spraying has special requirements for noise absorption and noise reduction in specific places.

Such as theaters, concert halls, computer rooms, auditoriums, wards, production rooms, etc., the performance of inorganic fiber spraying technology not only has environmental protection functions such as being odorless and non-volatile, but also has high-strength effects of flame retardancy and fire prevention (based on actual reports). , and due to the special treatment in combining multiple regions of raw materials and implementing processes, this technology has a sound absorption rate of up to 0.8.

3. At present, most exterior wall insulation uses the method of lining polystyrene or polyurethane boards on the base layer. In addition to the shortcomings of complex processes, harsh conditions, slow speed, etc., the main material used is organic (based on actual reports) For physical products, the aging period is relatively low (more than twelve or three years), which reduces their excellence. Organic (based on actual reports) materials are flammable when exposed to fire and essentially have no fire prevention (based on actual reports) capabilities, causing serious potential damage to the main body of the building. The inorganic fiber spraying technology system requires no special treatment on the base layer of the construction, is easy to operate, and is free of pollution during the construction process. The fire prevention capabilities (based on actual reports) meet the national flagship product standards, the working surface is firm for a long time, and it can adjust to aging fractures, shedding failures, etc. Disadvantages.

4. In recent years, large-scale lightweight steel structures (color steel plate structures) such as large factories, warehouses, machine docks, sports venues, waiting rooms (car halls), markets, etc., especially long-span arched roof buildings, traditional Thermal insulation technology is far from meeting engineering requirements and people's expectations. Inorganic fiber spraying technology is the best thermal insulation engineering solution.
