Preparation and characterization of flexible polyvinylchloride-copper composite films
(Smithers Rapra Technology, 2013)
Flexible PVC films are statically charged due to their low electrical conductivity. This creates fire threat during its handling. Conductive materials are added to films to prevent this. In the present study it was aimed ...
Methods of humidity determination Part II: Determination of material humidity
(Springer, 2008-12)
Part II covers the most common methods of measuring the humidity of solid material. State of water near solid surfaces, gravimetric measurement of material humidity, measurement of water sorption isotherms, chemical methods ...
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 ...
Methods of humidity determination Part I: Hygrometry
(Springer, 2008-12)
Part I of the short survey covers definitions of air humidity and the respective measuring methods such as hygrometry, psychrometry, dew point measurement, LIDAR hygrometry and humidity sensors. Techniques based on property ...
Effect of humidity on electrical conductivity of zinc stearate nanofilms
(Elsevier, 2007-07)
In this work, stearic acid (StAc) and zinc stearate (ZnSt2) nanofilms were deposited on glass and silver substrates using Langmuir-Blodgett (LB) film technique and their structural and electrical properties were investigated. ...
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. ...
The effect of bio-based plasticizer on the permanence and water vapour transport properties of PVC plastigels
(Serbian Chemical Society, 2008)
Novel formulations of PVC plastisols based on blends of bio-based and synthetic plasticizers were prepared and characterized. A traditional phthalate plasticizer, dioctylphthalate, was replaced in the plastisols studied ...
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 ...
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 ...
