本刊讯近日,维美德向市场推出一套全新的水冷压光技术。与普通造纸工艺相比,这套专利技术可提高压光效果。通常情况下,纸幅保持低温且挺直,则可获得最佳的压光效果,比如中试运行中,借助水冷技术,纸幅在进入压光机前被冷却。将中试型生产环境扩展到实际生产规模,通过喷雾器向纸面施加少量水,再由热风箱干燥,可实现这一过程。水冷压光技术的目的是在保持纸幅外观及其他特性的前提下,降低定量。这样可大幅节约能源和
Recently, Valmet introduced to the market a new water-cooled calendering technology. This patented technology enhances the calendering effect compared to ordinary paper making. Normally, the paper remains cold and straight, giving the best calendering effect, such as in pilot runs, where the paper web is cooled before entering the calender with water cooling. Pilot plant production environment will be extended to the actual scale of production, through the sprayer to the paper surface to apply a small amount of water, and then dried by a hot air box to achieve this process. The purpose of water-cooled calendering is to reduce the quantity while maintaining the appearance and other characteristics of the web. This can save a lot of energy and
