Polyurethane casting machineThe prospect of waterproofing market and the concrete effect of waterproofing construction

1. What is the application prospect of the integrated water-proof and heat insulation system of the rigid foam polyurethane pouring machine?

Answer: hard foam polyurethane pouring machine waterproofing and heat insulation integrated system set waterproof and heat insulation performance in a suit of characteristics, domestic in the application of the building roof in recent years, but in foreign countries have decades of history. It has mature technology, stable performance, long service life and broad market prospect. Product characteristics are ordinary coil or heat insulation products can not be compared.

2、hard bubble Polyurethane casting machine Is it necessary to use heat insulation coating to further improve the heat insulation coating for the surface layer of waterproof and heat insulation integration?

reply：Absolutely. Although the thermal conductivity of hardfoam polyurethane is very low, usually between 0.024 and 0.027 w/m/k, the surface needs to be protected to improve the mechanical strength and block the ultraviolet irradiation in sunlight. Generally, cement polymer mortar can be used for protection. For example, coating ceramic fluorocarbon thermal insulation coating or nano thermal reflection thermal insulation coating on the surface of mortar can further reduce the surface temperature under sunlight and reduce the heat storage of the system, which is beneficial to heat dissipation and extend the use time.

3, hard foam polyurethane pouring machine insulation in industrial or other areas of heat preservation and energy saving application?

Answer: rigid foam polyurethane is known among solid materials with the lowest thermal conductivity and the best thermal insulation performance (0.024w/m/k). It has a broad market in the area of medium and low temperature. It is used alone or in combination with industrial ceramic thermal insulation coating, with obvious energy saving and consumption reduction effect.

4. How much help will the use of industrial-grade thermal insulation paint reduce the energy consumption of the equipment?

Each type of industrial equipment receives different help in energy consumption due to different factors such as ambient temperature and frequency.
