With the development and popularization of building system insulation, spray rigid foam polyurethane plays a huge role in building system insulation. The spray rigid foam polyurethane insulation system solution can effectively reduce heating energy consumption per unit area and improve energy efficiency by reducing heat energy loss. On-site sprayed rigid foam polyurethane has excellent thermal insulation properties, good closed cell ratio, and is a good hydrophobic material. It is trusted in terms of quality and performance.
1. What is polyurethane spraying?
Polyurethane spraying is a polymer made of isocyanate and polyether as the main raw materials. It is mixed with special equipment and foamed on-site through high-pressure spraying with the help of various additives such as foaming agents, catalysts, and flame retardants. Polyurethane rigid foam is a new synthetic material with thermal insulation and waterproof functions. Its thermal conductivity is low, only 0.022~0.024W/(m².k). Polyurethane spray flame retardant grades B1 and B2 can be used.
Rigid polyurethane composite materials are divided into two components: isocyanate and composite polyether: commonly known as black materials and white materials. After the two are stirred and mixed in proportion, a polymerization reaction occurs to generate a polyurethane rigid foam with an independent closed-cell structure. It is an ideal organic low-temperature insulation material with small thermal conductivity, energy saving and shockproof, strong adaptability, and can be prefabricated. Molding, or on-site spray casting.
2. Characteristics of polyurethane spraying
Polyurethane spraying is widely used and is suitable for sound insulation and thermal insulation of exterior floors of industrial buildings, civil buildings, and steel structure factories.
Floor insulation project: According to the design requirements, rigid foam polyurethane is used as the main body, and can also be matched with facing layers such as perforated boards. It not only has the function of thermal insulation and sound insulation, but also is beautiful and has good decorative effect.
