水性油墨胶体及其热解特性的研究
STUDY ON COLLOID AND PYROLYSIS CHARACTERISTICS OF FLEXO WATER-BASED INKS
摘要
Abstract
The colloidal and pyrolysis characteristics of water-based ink were studied.The results showed that the average size and Zeta potential of both kind of water-based ink was more than 150 nm and -30 mV,respectively.Surface charge of fibres reached the point of zero charge (PZC) at a pH of 3.45 in the presence of surfactant in model pulp deinking system.Fibres surface charge would reverse from negative to positive as pH level was lower than 3.45.Thermogravimetry analysis showed that both of water-based ink and oil-based ink had two decomposition weight loss stages.The first decomposition stage of water-based ink would loss 51.14% weight with temperature lower than 100 ℃.The total weight loss of water-based ink and oil-based ink were 67.24% and 82.46%.关键词
