                香港马报免费资料最新:瓦楞纸印刷用水性油墨的使用知识

                一、瓦楞纸印刷用水性油墨的特性

                1. Characteristics of corrugated paper printing water-based ink

                1.水性油墨大致分为两类:

                1. water-based inks are roughly divided into two categories:

                (a)松香-马来酸改性树脂系列(低档);

                (a) rosin maleic acid modified resin series (low grade);

                (b)丙烯酸树脂系列(高档)。

                (b) acrylic resin series (high grade).

                2.两类水性油墨之特性比较:

                2. comparison of the characteristics of two types of water-based ink:

                二、对水性油墨性能的要求:

                Two. Requirements for the performance of water-based ink:

                1.长期存放沉淀后,经搅拌后应很容易再分散;

                1. after long-term storage and sedimentation, it should be easily dispersed after stirring.

                2.要有良好的流动性能和粘度;

                2. it is necessary to have good flow performance and viscosity.

                三、水性油墨技术参数

                Three. Technical parameters of water-based ink

                1.颜色:与标准样版近似

                1. color: approximate to the standard sample

                注:将检样和标准样相近而不相连地用手动展色轮展色对比。

                Note: contrasting the sample with the standard sample and using the manual color wheel.

                2.细度:小于20微米仪器:0-50微米刮板细度计。

                2. fineness: less than 20 micron instrument: 0-50 micron scraper fineness gauge.

                3.粘度:20秒±5秒仪器:RIGOSHA4#杯(25℃)。

                3. viscosity: 20 seconds + 5 seconds instrument: RIGOSHA4 cup (25 degrees Celsius).

                4.PH值:8.0-9.5仪器:便携式PH仪(PHB-2型)。

                4.PH value: 8 - 9.5 instrument: portable PH instrument (PHB 2).
