查询词典 alkali lye

NOVELTY - Alkali chemicals are added to the cyanogen group gold-containing liquid, to obtain an alkaline liquid. Zinc is added to the alkaline liquid, and the formed deposit is dissolved in aqua regia. A reducing agent is added to the deposit solution and a deposit is produced. Gold is then separated by heat-processing the deposit.

本发明的新颖性在于：将碱性化学物质添加到氰化含金液中，以获取碱液；将锌加入到碱液中，并将形成的沉积物溶解到王水中；然后在沉积溶液中加入一种还原剂，形成新的沉积物；最后通过加热处理沉积物来分离金。

Through the experiment research of the collisional energy transfer between the high-lying state of alkali molecules and the ground state atoms, we get the information in order to ascertain the atom molecule interaction potential energy and energy partition, and to seek new laser working energy levels.

通过对高位态碱分子和基态原子碰撞转移的实验研究，为确定原子分子相互作用势，碰撞粒子的能量和寻找新的激光工作能级提供信息实验数据。

The results suggested that chitinhad a good solubility in the new solvent when its at -30℃and below, but the solubilityof chitin no longer increasesd notable as the temperature reduced; The joined of urea, incertain degree, strengthened the solvency of alkali solvent to chitin. When theconcentration of sodium hydroxide is 8%～12%, Chitin had a good solubility, and theapparent viscosity of chitin solution could up to 4000 mpa·s～5000mpa·s at roomtemperature; In addition,the solubility of chitin in new solvent was high when therefrigerated time was three days and above, but the refrigerated time could not too long,otherwise, the deacetylize degree of chitin got more bigger. The properties of chitin solution were tested by revolving viscosimeter, FT-IR,X-RD and so on.

结果表明，在-30℃及以下甲壳素能很好的溶解于新溶剂中，但甲壳素的溶解度不再随温度的下降而有所增大，而是基本保持不变；尿素的加入，在一定程度上强化了强碱溶剂对甲壳素的溶解，当新溶剂中NaOH浓度为8％～12％时，甲壳素在试验温度下可以获得较好的溶解度，所得溶液在室温下的表观黏度达4000 mpa·s～5000mp·s；冷冻时间为3 d及以上时，有利于甲壳素的溶解，超过3 d，甲壳素的溶解度变化不大，另外，冷冻条件下，甲壳素在强碱溶剂中仍会发生脱乙酰化反应，冷冻时间不宜太长。

And the crust of alkali influents oil well a lot.

并且，碱引起的油层和油井结垢也对油田生产造成了严重影响。

An alkali or ionised cleaning or emulsified agent.
