消泡剂对中性墨水性能的影响

Effect of Defoaming Agent on the Properties of Gel Ink

摘要:

考察了乙炔改性聚硅氧烷乳液消泡剂对中性墨水表面张力、密度、黏度、pH和书写性能的影响。结果表明：消泡剂的加入，使得中性墨水表面张力小幅下降，对中性墨水黏度、pH没有显著影响，当消泡剂的质量分数为0.042%~0.043%时，消泡效果最佳，书写线条光滑饱满，出墨均匀性得到改善。

Abstract:

The effect of the acetylenic-modified polysiloxane emulsion defoaming agent on the surface tension, density, viscosity, pH value and writing performance of the gel ink was investigated. The results showed that the surface tension of the gel ink decreased slightly and the viscosity and pH value of the gel ink were not affected by adding the defoaming agent. The optimizational dosage of defoaming agent was 0.042wt%~0.043wt%. The pens filled with such gel ink behave good writing performance. And the uniformity of the amount of the gel ink consumed during writing was improved.
