【摘要】 本文研究了自制酮醛树脂圆珠笔油墨的流变特性。发现树脂含量和染料含量对油墨的流变特性有显著影响。在此基础上,提出了一个性能优良的新配方,它的流变特性参数n=0.91,K=6.89N·s~n/m~2,ηa=5.83Pa·s。所得实验结果,可供改进现有国产圆珠笔油墨的质量作参考。更多还原

【Abstract】 The rheological properties of inks for ball-point pen were studied experimentally. These inks were made by ketonic aldehyde resin in laboratory. The flow parameters of these inks were determined by using cone-and-plate-system viscometer, Rheotest-2. All of the inks tested exhibit Non-Newtonian power law fluid behavior. The experimental data show evidently that the content of the main components, such as dye and resin, of the ink has a significant influence on its theological properties. Based on the study, a new prescription of high-quality ink was developed. Its flow parameters are shown as follows: n=0.91, K=6.89 N.sⁿ/m², and η₂= 5.83pa·s. The results obtained may be used to reform the properties of available inks for ball-point pen.更多还原
