本试验在严格控制的条件下,用实验室退火炉对铝箔退火过程中发生的化学反应进行了研究,同时还用气相层析法研究了气相中的反应动力学。本文叙述了时间、温度、退火炉炉气中水分和氧气的含量对反应和退火铝箔粘结性(自由展开)的影响。研究表明:铝箔的粘结程度与在有氧的情况下铝和水反应生成的氧化铝的量成同步增长。试验中还确认了一些由残余轧制油产生的有机反应产物,这些反应产物绝大部分是羧酸、羧基化合物和醇类。
In this experiment under strict control conditions, the use of laboratory annealing furnace annealing process of aluminum foil chemical reactions were studied, but also by gas chromatography reaction kinetics in the gas phase. This article describes the effects of time, temperature, moisture and oxygen content in the furnace gas on annealing and annealed aluminum foil adhesion (free expansion). Studies have shown that the degree of adhesion of aluminum foil increases in tandem with the amount of alumina produced by the reaction of aluminum with water in the presence of oxygen. The test also confirmed that some of the organic reaction products produced by the residual rolling oil, the reaction products are mostly carboxylic acid, carboxyl compounds and alcohols.
