摘要:
实验以国产活性黑粗染料为原料,采用微滤膜除杂、荷电镶嵌膜恒容脱盐和纳滤膜脱水浓缩工艺制备高纯度、高浓度液体活性染料;并通过喷雾干燥制备了高纯固体活性黑.实验结果表明:针对染料含量为61.5 g/L的原料液,在操作压力1.0 MPa条件下,脱盐8h染料纯度达到要求,染料损失率为0.62％;脱盐过程中荷电镶嵌膜的平均透过通量约为18.5 L·m-2· h-1.在1.4～1.8 MPa下,可将高纯料液脱水浓缩,使活性黑浓度达到250 g/L.实验采用喷雾干燥法制备固体染料,经分析该产品的无机盐含量低于企业目前所用的进口产品,具有良好的应用前景.
Abstract:
In this paper , the high purity liquid reactive black was prepared by using the membrane separationtechnology ,including the microfiltration(MF) membrane for removing particulate，the Charged-mosiac ,mem-brane(CMM) for desalination in the constant-volume filtration and the nanofiltration(NF) membrane for dehy-dration.The solid reactive black with high purity was prepared by spray drying.The experimental results showthat with the 61.5 g ·L ’ raw material liquid，under the pressure of 1.0 MPa, the salts were removed after 8hours desalination.The purity of dye could meet the requirement and the loss rate of the dye was 0.62% . Theaverage permeation flux of the charged-mosiac membrane was 18.5 L· m .h-’ during the desalinationprocess,which illustrated that the fouling of membrane was not so serious. Under the pressure of 1.4-1.8MPa , the reactive black concentration can achieve 250 g·L ’ by dehydration. The solid dye was prepared bythe spray drying.It was analysed that the inorganic salt in the product was lower than the imported productused by the enterprise. To sum up, the product prepared in the experiment has a good application prospect.
