Water-soluble metal working fluids are used for processing of aluminum alloy materials. This short article describes properties of new additives in water-soluble metal working fluids for aluminum alloy materials. Many half esters or diesters were prepared from the reactions of higher alcohols with acid anhydrides. Interestingly, diesters of PTMG (tetrahydrofuran oligomer, MW = 650 and 1000) and polybutylene oxide (MW = 650) with maleic anhydride and succinic anhydride showed both of an excellent anti-corrosion property for aluminum alloy and a good hard water tolerance. The industrial soluble type processing oils including these additives also showed anti-corrosion property and hard water tolerance.
水溶性金属加工液用于铝合金材料的加工。这篇短文描述了用于铝合金材料的水溶性金属加工液中新型添加剂的性能。许多半酯或二酯是由高级醇与酸酐反应制备而成。有趣的是，聚四氢呋喃（MW = 650和1000）和聚环氧丁烷（MW = 650）与马来酸酐和琥珀酸酐的二酯对铝合金显示出优异的抗腐蚀性能和良好的耐硬水性能。包含这些添加剂的工业可溶性加工油也表现出抗腐蚀性能和耐硬水性能。
