板带钢冷轧乳化液稳定性与润滑性研究

研究了影响乳化液稳定性的几个因素,包括乳化液的HLB值、乳化剂的种类与复配类型、乳化剂的用量及乳化剂化学结构与基础油的相似程度等。结果表明,乳化液的HLB值等于油品被乳化所需的HLB值,乳化剂总量占12%～15%,所选乳化剂的HLB值越接近乳化液的总体HLB值,且其化学结构与基础油的结构越相似,乳化液的稳定性越好;乳化液的均一性与乳化液的总体稳定性具有一致性;在一定的范围内,乳化液的稳定性越好,润滑性能越差。

AN INVESTIGATION OF THE STABILITY AND LUBRICITY OF EMULSIONS FOR STRIP COLD ROLLING

Factors affecting the stability of emulsions, such as HLB (hydrophile lipophile balance) value of emulsions, the types of emulsifiers and their combinations, the amount of emulsifiers and the structure similarity between emulsifier and base oil, are investigated. The results show that good stability of an emulsion could be obtained when the HLB value of an emulsion is equal to that of the oil being emulsified, the total amount of emulsifiers is in the range of 12%-15%, the HLB value of selected emulsifier is close to that of the emulsion, and the chemical structures of the emulsifiers are quite similar to those of the base oil. The homogeneous emulsions usually have good stability, yet in a certain extent, the emulsions having good stability exhibit bad lubricity.
