Performance characteristics of rigid foam polyurethane casting machine

After years of testing by our companys technicians,hard bubblePolyurethane casting machineThere are waterproof and heat insulation integration system set waterproof and heat insulation performance at the characteristics of a suit, when the application of the building roof in recent years emerged, but abroad has 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.

Rigid foam polyurethane casting machine

Rigid foam polyurethane casting machineIs it necessary to use heat insulation coating to further improve the heat insulation coating for the surface layer of waterproof and heat insulation integration?

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.
