ADVANTAGES OF THE FUTURE DEVELOPMENT OF SMALL POLYURETHANE FOAMING EQUIPMENT

In recent years, the country has attached great importance to energy conservation and emission reduction. The use of small polyurethane foam equipment to spray exterior walls is an energy-saving and environmentally friendly green project. Prioritizing energy conservation has become a strategic decision for China’s sustainable energy development. External thermal insulation technology and products are facing good development opportunities and should be promoted and applied vigorously.

After the external insulation, due to the large heat capacity of the internal solid wall, more heat can be stored indoors, which slows down the indoor temperature changes caused by solar radiation or intermittent heating, the room temperature is more stable, and life is more comfortable; it also makes the sun The "free heat" generated by factors such as radiant heat, heat dissipation from the human body, heat dissipation from household appliances and cooking is better utilized, which is beneficial to energy saving. In summer, the external thermal insulation layer can reduce the comprehensive influence of solar radiant heat and high outdoor temperature, so that the internal surface temperature of the external wall and the indoor air temperature can be reduced. It can be seen that the external insulation of the external wall is beneficial to make the building warm in winter and cool in summer.

The exterior wall thermal insulation sprayed by small polyurethane foaming equipment has two significant advantages: thermal insulation and thermal insulation. The thermal insulation and thermal insulation performance of the building envelope (including the roof, external walls, doors and windows, etc.) is very important for the indoor thermal environment in winter and summer. Heating and air-conditioning energy consumption has an important influence. Buildings with excellent thermal insulation and thermal insulation performance of the envelope structure not only have a good indoor environment for warm in winter and cool in summer, but also have low energy consumption for heating and air conditioning. External insulation of external walls can also improve the comfort of people's living environment.
