Experts'research on the stability of water-based ink and process has been a preliminary study. Femandez and other matozoa of the discovery of water-based ink by electrostatic repulsion stability and space steric 's. Aromtics and gecol, and so on the surface of the plastic film studies indicate that water-based inks, join different types of surfactants can be effective removal of water-based inks, and Canadians zephiramine hexadecyl alkyltrimethylammonium can make the surface charge of carbon black particles.
国际学者差火性油墨的稳不退性和脱除工艺已举行了开端查究。femandez等发掘火性油墨的胶体稳不退性是由静电排不引力和不满答位阻效应成群不决的。gecol等差脱除塑料薄膜暗不天的火性油墨查究后暗示,参加差别种类暗不天活性剂均可灵验去除火性油墨,而且加人阳离子暗不天活性剂十六烷基不一甲基溴化铵可以使炭暗粒子暗不天电荷逆转。

The results show that the optimal parameters of esterification are as follows: 4% of SO42-/ZrO2, molar ratio of methanol to litsea cubeba kernel oil 101, 68 ℃ of reaction temperature and 4 h of reaction time, the acid value decreases to 2.52 mg/g. Compared with the traditional acidic-catalyzed method, this method has the advantages of no acid proof equipment, easy to recycle catalyst and no acidic waste water emission. The optimal parameters of transesterification are as follows: 25 ℃ of reaction temperature, 0.5% of hexadecyl-trimethyl-ammonium bromide, 1% of NaOH, molar ratio of methanol to the oil 61 and 15 min of reaction time. The ester exchanging rate is 97.6%. This method adopts phase transfer catalyst and produces industry prospect, which has many advantages such as energy-saving and time-saving under room temperature.
