可擦墨水的研制

Operational development of erasable ink

硝化纤维素作成膜剂 ,采用乙醇、丙酮等复合溶剂 ,甘油和表面活性剂作性能调节剂 ,通过对研磨工艺和pH控制的试验 ,制得成本较低、气味小、书写性能优良的可擦性墨水。

The nirto-cellulose as film forming agent,ethanol and acetone as composite solvent,glycerin and surfactant as performance modifying agent, by means of experiment on ground and pH controls,it can make a kind of erasable ink whose characteristics include lower cost,small odour and easy to write.
