Most of the exterior wall insulation of existing building energy-saving renovation adopts thin plastering external insulation paste system,which leads to cracking and water infiltration in the rainy season due to non-standard splicing construction in node parts(such as yin and yang corners),and even the problem of large-scale falling off of thermal insulation due to freezing and thawing,which has caused a series of safety problems.The above shortcomings can be solved by using polystyrene modules.Because the design and processing technology of graphite polystyrene module is produced by molds,the number of molds used is large,the efficiency is low,and the labor cost is high,and the economic and social benefits can be improved by changing the processing technology.This paper discusses the application value and process improvement of graphite polystyrene module,which can be used as a reference for similar transformation projects.
