Studies on removing CFC-11 by heating from discarded rigid polyurethane foams

A environmental friendly treating process on waste rigid polyurethane foam frothed with R11 vesicant is brought forward.

The paper provided some pieces of advice for the direction of the polyurethane application after the standard of Classification for Burning Behavior of Building Materials and Products(GB 8624-2006) had been carried ou.

5×10~6 m~2/y polyurethane foam composite panel continuous production line was developed by Xiang- tan Jingzheng Equipment Manufacture Co.

In order to solve the problem of the energy-wasting of numerious existing buildings’ roofs, the authors made an analysis and research on the energy-wasting of the existing buildings’ roofs and proposed that the polyurethane foam should be used to rebuild the non-energy saving buildings’ roofs.

Application research of new green-blowing agents in rigid polyurethane foam;

Research progress on the modification of rigid polyurethane foam;

The hybrid rigid polyurethane foam was prepared using nylon 66 fiber and SiO_2 particle as reinforcing agents, which can distinctly improve its mechanical properties including tensile strength, compressive strength and impact strength.
