The effect of zinc stearate on thermal degradation of paraffin wax
(Springer, 2008-12)
In this research, the effects of zinc stearate addition on paraffin wax degradation were investigated by differential scanning calorimetry (DSC) and thermogravimetry (TG). The apparent activation energies of wax decomposition ...
A study of chemical and physical changes during biaxially oriented polypropylene film production
(Walter de Gruyter, 2003)
Polypropylene films obtained during the biaxial orientation process were characterized by energy dispersive X-ray analysis (EDX), scanning electron microscopy. X-ray diffraction, differential scanning calorimetry, infrared ...
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. ...
Effect of additives on flexible PVC foam formation
(Elsevier, 2008-01)
In this study, effects of Ca/Zn stearate and organotin heat stabilizers and zeolite, CaCO3, cellulose and luffa flours fillers, and their concentrations (2.5, 5, 10 and 20% by weight) on production of flexible PVC foams ...
Characterization of poly(vinyl chloride) powder produced by emulsion polymerization
(Springer, 2010-08)
The effect of emulsion process formulation ingredients on the morphology, structure, and properties of polyvinyl chloride (PVC) powder has been considered in this study. PVC powder was extracted with ethanol and films were ...
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 ...
A study of adsorption of water vapour on wool under static and dynamic conditions
(Kluwer Academic Publishers, 1998-01)
Adsorption of water vapour on wool provides not only textile comfort, but also convenience in transportation due to increase in its bulk density. The adsorption and desorption isotherms of water vapour for wool were ...
Flexible poly(vinyl chloride)-zeolite composites for dye adsorption from aqueous solutions
(Taylor & Francis, 1996)
Flexible poly(vinyl chloride) (PVC) composites having natural zeolite clinoptillolite were prepared by plastisol-plastigel technology. Adsoption of methylene blue on each raw material and on composites was studied both ...
Batch and column studies on heavy metal removal using a local zeolitic tuff
(Elsevier, 2010-09)
Ion exchange is considered to be one of the most cost effective methods if low cost ion exchangers such as natural zeolites are used in waste water treatment. In this study, a zeolitic tuff rich in clinoptilolite from ...
Cure kinetics of epoxy resin-natural zeolite composites
(Springer, 2008-12)
The cure kinetics of epoxy resin and epoxy resin containing 10 mass% of natural zeolite were investigated using differential scanning calorimetry (DSC). The conformity of the cure kinetic data of epoxy and epoxy-zeolite ...
