The estimation of environmental degradability of different ramie fibre reinforced biocomposites in Baltic Sea water and in compost with activated sludge under natural conditions is the subject of this paper. The characteristic parameters of environments were monitored during incubation time and their influence on the rate of degradation of biocomposites was discussed. The degradation processes of...
Badania obejmowały degradację środowiskową poli(e-kaprolaktonu) (PCL) w rozmaitych warunkach naturalnych, a także w środowisku eliminującym działalność organizmów żywych. Przebieg degradacji oceniano na podstawie zmian masy PCL oraz jego ciężaru cząsteczkowego i struktury powierzchni w warunkach różnej temperatury i pH środowiska. Ustalono, że w badanych naturalnych środowiskach degradacja jest rezultatem...
This paper presents results of biodeterioration of Mater-Bi YI01U under natural weather conditions in compost with sewage sludge. The tests were performed at a waste treatment plant and - for comparison - under laboratory conditions at stable temperature. The compost pile was prepared outdoors at a waste treatment plant and consisted of active sludge, burnt lime /CaO/ (to ravage pathogenic bacterium...
The comparison of degradation of modified poly(e-caprolactone) film in different environments is presented. Poly(e-caprolactone) was incubated in a natural environment ± sea water (the Baltic Sea), in buffered salt solution, in liquid medium containing sea water with NaN3 and in compost with plant treatment activated sludge (under natural and laboratory conditions). The characteristic parameters of...
Oceniono wpływ różnych modyfikatorów i dodatków procesowych na szybkość biodegradacji poli(e-kaprolaktonu) (PCL) w warunkach naturalnych - w kompoście z osadem czynnym i w wodzie morskiej. Badania obejmowały PCL modyfikowany skrobią, kredą albo dodatkami procesowymi, czyli poli(akrylanem etylenowo-butylowym) (EBA) z utleniaczem lub układem Master Batch (MB) składającym się z PE-LD oraz amidów kwasu...
