高温分解

The replacement of SF6 by refrigerant is under development. For example, R143a by AMC and FK by 3M Co. used as protection gas are both classified as HFC with short atmospheric lifetime and are easily to be decomposed into hydrofluoric acid, carbon monoxide and fluoric carbon monoxide at room temperature.

目前发展中的替代性保护气体以冷媒类为主，如澳洲AMC所采用的R134a及美国3M公司所开发的FK气体，两者都属於氟氢碳化合物，不过其半衰期短，即使在常温下，仍极易分解成氢氟酸、CO、COF2等，其中氢氟酸为有害物质，但因含量很少，且在高温下易与镁液反应，故对人体的为害很小。

Thermodynamic process of direct aluminium extraction from aluminium sub-sulphide, which is unstable and easily decomposed into Al and Al2O3 at a low temperature, was analytically studied. The temperature, at which alumina, FeS and carbon react to form aluminium sub-sulphide in different pressure, was evaluated with "Substance Gibbs' Free Energy Functional Determinant" method.

The investigation also showed that, the antioxidants with same action mechanism, for example, as both radical scavengers, phenol and amine antioxidants are synergistic; but the synergistic effects between two antioxidants with different action mechanism, such as radical scavenging phenol and amine antioxidants, and hydroperoxide decomposing ashless dithiocarbamate, are much stronger, and the heterosynergism between dithiocarbamate and alkylated diphenylamine is outstanding, which can serve as high temperature ashless high performance antioxidant combination; the heterosynergism among three antioxidants with three different action mechanisms, for example, the tri-component combination of alkylated diphenylamine, zinc dithiocarbamate and organic molybdate ester, can achieve excellent antioxidation performance.

研究还表明，具有相同抗氧机理的不同抗氧剂，如酚类和胺类抗氧剂，具有协同作用；不同作用机理的两抗氧剂之间，如自由基清除剂和氢过氧化物分解剂，具有更好的抗氧化协同效果，其中，无灰氨基甲酸酯与烷基化二苯胺抗氧剂具有最佳的抗氧协同效能，可成为高温无灰抗氧剂应用的一个很好选择；不同抗氧机理的三种抗氧剂复合，如烷基化二苯胺，氨基甲酸锌和有机钼酸酯组成的三元复合抗氧剂，具有更为优秀的抗氧化性能。
