Research On The Amplification And Establishment Of Viscosity Model Of Water-Based Drawing Oil System

In order to solve the problem of water-based drawing oil which can not be applied to the production of steel stamping workshop in the cold winter of the north,ethylene glycol is chosen as an additive in this paper to improve its properties.And at the same time in order to more easily obtain the raw material ratio of the water-based drawing oil corresponding to the drawing viscosity demand of the different stamping parts,the water-based drawing oil viscosity model was established.The viscosity model was established and validated for three sample systems.At different temperatures,The high viscosity and solid components were diluted and adjusted with water and ethylene glycol as solvent and diluent for the complete water-soluble extended-oil system of three different proportions of Newton and non-Newton mixed systems.The four parameters model which used to predict the viscosity and the relationship between the model parameters and the content of additive are obtained by the regression calculation of the Eyring equation and the equation model using the linear least squares method and the nonlinear least squares method.The average relative percentage error of the equation is A1:15.67%,A2:18.16%,B1:19.48%.The model satisfies the engineering amplification requirements and can be used for the viscosity prediction of the hybrid system.For having a better adaptation to the demands of production,the enlarged treatment in synthesizing the water-based drawing oil was carried out in this paper.As a result of the replacement of raw materials,the small test and pilot synthesis route were explored and studied first of triethanolamine borate,triethanolamine fatty acid salt and water-based drawing oil in this paper.The optimum formulation of water-based extended oil was determined by comparison test,amplification and viscosity determination.Then,the moderate and slightly stretched formulations of the stretched oil system are confirmed by the severe stretching formulation.The method is to add a moderate amount of water to the severe stretching formulation system,dubbed eight sample systems,and then determine the viscosity of each sample.Finally,nine water-based oil samples were tested and the result meets the requirements.The formulation of the water-based drawing oil for the severe,the moderate and slightly stretched has been successfully developed,which has a certain reference value for guiding the production of industry.
