The high pulverization ratio of phenolic foam is restricted by its application range so it is necessary to test and analyze the pulverization ratio of modified phenolic foam Figure 6 a presents the pulverization ratios of the PF FPFs and FTPFs The pulverization ratio of pure phenolic foam PF was the highest at % indicating brittleness
Phenolic foam composites PFs are of substantial interest due to their uniform closed cell structure low thermal conductivity and good thermal insulation performance However their disadvantages of a high pulverization rate and poor mechanical properties restrict their application in building exterior insulation Therefore the toughening of these composites

Scalable Mesh Refinement for Canonical Polygonal Schemas of Extremely High Genus Shapes Abstract Any closed manifold of genus g can be cut open to form a topological disk and then mapped to a regular polygon with 4g sides This construction is called the canonical polygonal schema of the manifold and is a key ingredient for many applications
Pulverization Pilling and Extrusion DOI link for Pulverization Pilling and Extrusion Pulverization Pilling and Extrusion powder is passed 100% through a 6 mesh screen whereas if it must find its way into ⅜ in dies to make ⅜ in pills then the powder should be passed 100% through a 10 or 12 mesh screen Finer powder is
A Mesh After a single factor test on the mesh level the mesh level is set to 40 mesh 80 mesh and 120 mesh The larger the particle size of the powder the more it can preserve the thermal insulation properties of the polyurethane foam itself but too large particles will reduce the bond strength of the polyurethane foam powder and
