Application of polyurethane heat preservation pipe products: suitable for heat preservation and cooling engineering of various media in the range of - 50 ~150 C. It is widely used in urban central heating, heating room, cold storage, coal mine, oil port, air conditioning, chemical industry and other industries. The application of polyurethane direct-buried heat preservation pipeline technology marks a new starting point for the development of heating pipeline technology in China. With the decrease of world energy and the increasing demand for energy, energy saving, emission reduction and environmental protection have become the trend of global development. National and central governments also strongly advocate the development, application and industrialization of energy saving, emission reduction and environmental protection products.
Polyurethane rigid foam thermal insulation material for construction industry is an important branch of polyurethane industry. It has the characteristics of multi-purpose material, thermal insulation, waterproofing and other functions. This kind of product has been used in European construction industry for 40 years since 1960s. Some countries have legislated to use polyurethane as thermal insulation and waterproofing material designated by the construction industry. In recent years, with the rapid development of building energy-saving market in China, polyurethane rigid foam thermal insulation products have been widely used in the field of building thermal insulation and waterproofing, and have become one of the leading market thermal insulation and energy-saving products.
As an integral information of building insulation and waterproofing, polyurethane rigid foam breaks through the common fault of single function of traditional building materials - Waterproofing without thermal insulation and thermal insulation without waterproofing. Once the waterproofing layer appears leakage, the thermal insulation layer loses its thermal insulation function. Compared with other single function heat preservation or waterproofing materials, polyurethane rigid foam has obvious advantages:
1. Polyurethane rigid foam has many functions, such as heat preservation, waterproof, sound insulation, vibration absorption and so on.
2. Excellent thermal insulation performance, is the current domestic building materials in thermal conductivity * (< 0.024), thermal resistance value * thermal insulation data, thermal conductivity is only half of EPS foamed polystyrene board.
3. Polyurethane rigid foams have continuous and compact epidermis and close-cell walls with high strength interconnection of nearly 100%. They have ideal impermeability. Spraying method is used to construct continuous seamless waterproof insulation layer, which forms seamless roof and whole external wall insulation shell. The waterproof and impermeability performance is excellent.
4. Super self-adhesive property (without any intermediate bonding data) and strong bonding with roof and exterior wall, good anti-wind exposure and negative wind pressure performance; integral spraying construction, complete elimination of "hot spot" and "cold bridge"; flexible mutation technology can effectively prevent cracking of waterproof layer; mechanized operation, automatic proportioning, uniform quality, fast construction The cycle is short.
5. The chemical property is stable, the service life is long, and it does not pollute the surrounding environment; the open flame extinguishes itself, and only carbonization does not drip when it extinguishes. The size and shape of the carbonization layer are basically unchanged, which can effectively cut off the entry of air, prevent the spread of fire, and have good fire safety performance.
