Abstract

The purpose of this study is to investigate the effect of polyvinyl alcohol (PVA) on rheological and dielectric properties of suspension in the different concentration of PVA prepared by using kaolinite 0.1%. The viscosity values of suspension have been measured and the dependence of viscosity on temperature and concentration have been investigated. The specific viscosity and activation energy have been calculated by using the measured viscosity values. It has been observed that the values of viscosity increase exponantially with the concentration of PVA and decrease with increasing temperature. Dielectric constants of suspensions prepared by using PVA-deionized water and PVA-water-kaolinite have been measured in the temperature range from 0°C to 15°C, and its dependence on concentration and temperature also investigated. It has been observed that dielectric constant slightly increases with PVA concentration, but decreases with increasing temperature.

Özet

Bu çalışmanın amacı % l kaolin kullanarak değişik PVA konsantrasyonlarında hazırlanmış süspansiyonun reolojik ve dielektrik özellikleri üzerinde polivinil alkol(PVA)ün etkisini araştırmaktır. Süspansiyonun viskozite değerleri ölçülmüş ve viskozitenin sıcaklık ile konsantrasyona bağlılığı incelenmiştir. Ölçülen viskozite değerleri kullanılarak spesifik viskozite ve aktivasyon enerjisi hesaplanmıştır. Viskozite değerlerinin PVA konsantrasyonu ile eksponansiyel olarak arttığı ve artan sıcaklıkla azaldığı gözlenmiştir. PVA-deiyonize su karışımlarının dielektrik sabitleri ve PVA-su-kaolin ile hazırlanan karışımların dielektrik sabitleri 0°C-15°C sıcaklık aralığında ölçülmüş, sıcaklık ve konsantrasyon bağlılıkları incelenmiştir.Dielektrik sabitinin PVA konsantrasyonu ile yavaş artış gösterdiği ve artan sıcaklıkla azaldığı gözlenmiştir.
