Optimisation of the effect of colemanite as a new synergistic agent in an intumescent system
An intumescent system including ammonium polyphosphate (APP) as an acid source and blowing agent, pentaerythritol (PER) as a carbonific agent and colemanite as a synergistic agent is used to enhance flame retardancy of ...
Dynamic heat of adsorption of water vapour on zeolitic tuff and zeolite 4A by flow microcalorimetry
In this study a practical method for measurement of heat of adsorption of water vapour on adsorbents was developed to evaluate the feasibility of substitution of a zeolitic tuff with zeolite 4A in air drying and heat pumps. ...
Influence of surface modification of fillers and polymer on flammability and tensile behaviour of polypropylene-composites
An intumescent system consisting of ammonium polyphosphate (APP) as an acid source and blowing agent, pentaerythritol (PER) as a carbonific agent and natural zeolite (clinoptilolite, Gördes II) as a synergistic agent was ...
Moisture sorption and thermal characteristics of polyaramide blend fabrics
Four types of fabrics woven from various polyaramid fibers of Nomex and Kevlar blends were characterized by morphology, XRD, elemental analysis, thermal analysis, and moisture adsorption isotherms. The blends consisted of ...
Effect of zeolite filler on the thermal degradation kinetics of polypropylene
In this study, the thermal degradation behavior of polypropylene (PP) and PP-zeolite composites was investigated, Clinoptilolite, a natural zeolitic tuff, was used as the filler material in composites. The effects of both ...
