Advantages and Maintenance Knowledge of Polyurethane Thermal Insulation Pipeline
Special type polyurethane insulation pipes should be used in the center where the environment is bad and the environment is demanding. For example, boiler high-pressure polyurethane insulation pipeline, mineral polyurethane insulation pipeline, petroleum polyurethane insulation pipeline and other industries, polyurethane insulation pipeline in use, if not properly maintained, will lead to polyurethane insulation pipeline function reduction.
The interior is far away from corrosive objects. Although the polyurethane insulation pipeline is very thick, the interior is destroyed, which can also affect the function of polyurethane insulation pipeline. For example, cover up all kinds of corrosive objects on the pipe wall, temporarily in such an environment. Pipelines can be destroyed, and they can leak easily when conveying fluids, or their functions may be reduced.
1. Polyurethane thermal insulation pipeline has a multi-purpose function, but also has many functions such as thermal insulation, waterproof, sound insulation and vibration absorption.
2. The function of thermal insulation is outstanding. It is the lowest thermal conductivity (<0.024) and the highest thermal resistance of all building materials in the world. The thermal conductivity of EPS foamed polystyrene board is only half of that of EPS foamed polystyrene board.
3. The polyurethane insulation pipeline body has a continuous dense skin and nearly 100% high strength interconnected wall closure, which has an ideal impermeability. Spraying method was used to construct the waterproof and thermal insulation layer with continuous seamless, which constituted a seamless roof and shell of external wall thermal insulation. The waterproof and impermeable function was excellent.
4. Super self-adhesive function (without any bonding data at both ends), strong bonding with roof and exterior wall, good anti-wind exposure and anti-negative wind pressure function; all spraying construction, can completely eliminate the "hot spot" and "cold bridge"; flexible mutation technology can effectively prevent the cracking of waterproof layer; mechanized operation, automatic ingredient, uniform quality, fast construction and short cycle.
5. The chemical property fluctuates, the service life is longer, and the surrounding environment will not be purified; separate open fire will automatically extinguish, and when extinguished, only carbonization will not drip, the size and shape of the carbonization layer is basically unchanged, which can effectively block the entry of air, prevent the spread of fire, fire safety function is good.
