The European LIFE Project, Repolyuse – “REcovery of POLYurethane for reUSE in eco-efficient materials” seeks to solve the environmental challenge resource scarcity and waste management order mitigate effects climate change. material is a prefabricated gypsum mortar form removable roofing plate which residues rigid polyurethane foam have been added. That system reduces weight plates about 30%. i...
In this paper, high density rigid polyurethane foam is used as sandwich skeleton and shear thickening fluid material core. A fluid/polyurethane structure with light impact resistance was designed fabricated. High strain rate test carried out. It found that STF-2/PU reached the peak load of 4978N in 13 ms after receiving 20 J energy, energy absorption ratio 43%. The honeycomb prepared by seconda...
Sampling medium side resistance to uptake of semivolatile organic compounds in passive air samplers.
Current theory of the uptake of semivolatile organic compounds in passive air samplers (PAS) assumes uniform chemical distribution and no kinetic resistance within the passive sampling media (PSM) such as polystyrene-divinylbenzene resin (XAD) and polyurethane foam (PUF). However, these assumptions have not been tested experimentally and are challenged by some recently reported observations. To...
To select the best available packing material for malodorous organic gases such as toluene and benzene, biofilter performance was compared in biofilters employed different packing materials including porous ceramic (celite), Jeju scoria (lava), a mixture of granular activated carbon (GAC) and celite (GAC/celite), and cubic polyurethane foam (PU). A toluene-degrading bacterium, Stenotrophomonas ...
Nowadays, the investigation of both classic and new materials for blast mitigation applications is a subject intensively approached in scientific literature. Due to their mechanical behavior, polyurethane foams are with high potential this type applications. Within current paper EUROPLASTIC� foam grade mixed fly ash ceramic micro powder was experimentally investigated. Using single stage gas gu...
