挤水基墨生产工艺流程 与颜料相比，挤水基墨重量较大，运输成本较高；通用性较低；具有更优异的鲜艳度、透明度及较高的 着色力；且不产生粉尘，环保性较高。对于下游客户而言，挤水基墨简化了油墨企业的生产工序；解决 油墨企业客户废水处理能力不足的问题。 颜料和挤水基墨特点对比 内容概要：挤水基墨是颜料制备油墨过程中形成的中间产品，相较于颜料，向油墨客户提供挤水基墨可 以简化其生产工序，减少其污染物产生量，提高其产量及生产效率，同时解决中小型油墨企业挤水基墨 生产规模受限、废水处理能力不足、粉尘污染等一系列问题。目前，挤水基墨已在国外得到广泛应用， 如美国约有80%的油性油墨是用挤水基墨生产而成的。而在中国，受运输成本等因素，国内油墨企业仍 以采购颜料为主，挤水基墨需求较少。数据显示，2020年以来，受市场需求疲软影响，中国挤水基墨行 业市场规模呈现下降趋势，到了2025年行业市场规模达到3.2亿元，同比小幅上涨1.9%。 相关上市企业：联合化学（301209）、杭华股份（688571）、科德教育（300192）、信凯科技 （001335）、百合花（603823）、双乐股份（301036）、七彩化学（300758）、东方 ...
