Optimisation of the effect of colemanite as a new synergistic agent in an intumescent system
(Elsevier, 2006-07)
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 ...
Synergistic effect of natural zeolites on flame retardant additives
(Elsevier, 2005-09)
The thermal degradation and flammability of intumescent fire-retardant polypropylene matrix composites consisting of ammonium polyphosphate (APP) as an acid source and blowing agent, pentaerythritol (PER) as a carbonisation ...
A chromatographic study of carbon monoxide adsorption on a clinoptilolite-containing natural zeolitic material
(Taylor & Francis, 2004-11)
In this study, the equilibrium and kinetic parameters for CO adsorption on clinoptilolite-rich natural zeolitic material were determined by the concentration pulse chromatography technique. Experiments were carried out at ...
Characterization of pure and silver exchanged natural zeolite filled polypropylene composite films
(Elsevier, 2005-10)
In the present study, untreated and silver exchanged natural zeolite-polypropylene (PP) composites were prepared and characterized by means of different techniques (TGA, DSC, mechanical tests, density measurements, optical ...
Water and water vapor sorption studies in poly(propylene)-zeolite composites
(Wiley, 2003-10)
Water and water vapor sorption to porous poly(propylene)zeolite composites prepared by hot pressing have been studied as a function of zeolite loading. This work presents the first report on the effect of the zeolite as a ...
Adsorption characteristics of lead-, barium- and hydrogen-rich clinoptilolite mineral
(Multi-Science Publishing, 2003)
The carbon dioxide and water vapour adsorption properties of local clinoptilolite-rich material, both as the original and as lead-, barium- and hydrogen-rich forms, were examined. The lead- and barium-rich forms were ...
Dynamic heat of adsorption of water vapour on zeolitic tuff and zeolite 4A by flow microcalorimetry
(SCIBULCOM, 2006)
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. ...
Synergistic effect of metal soaps and natural zeolite on poly(vinyl chloride) thermal stability
(Society of Plastics Engineers, 2005-06)
The synergistic effect of metal soaps (zinc stearate and calcium stearate) and/or natural zeolite (clinoptilolite) on PVC thermal stability was investigated. For this purpose, PVC plastisol was prepared by mixing poly(vinyl ...
Acylation of 2-methoxynaphthalene over ion-exchanged β-zeolite
(Elsevier, 2002)
Friedel-Crafts acylation of 2-Methoxynaphthalene was carried out over various ion-exchanged β zeolites (Mn+β, where Mn+: In3+, Zn2+, Al3+, Fe3+, La3+) with various anhydride (acetic, propionic and benzoic anhydrides), or ...
Influence of surface modification of fillers and polymer on flammability and tensile behaviour of polypropylene-composites
(Elsevier, 2006-05)
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 ...
