Abstract：
The key characteristics of on-site puring pdoywethane from withｏｕｔ demoulding in extｅｒnal thermal insulation technology includeｓ low wastage and pollution created in the process of pouring polyurethane foam poured in the closed formwork.The surface roughness of the thermal insulation layer was effectively controlled by the formwork.Integrating with the application in the construction project,some issues about the packaged technology were discussed,which include the structure measures,the indexes of accessories performance,equipment performance,pouring technology,construction technology,integrated properties and so on.
