摘要
目的探索环境温湿度对镀铝纸变形的影响规律,获得镀铝纸存储的最佳温湿度范围。方法将3种镀铝纸分别裁成大小不同的2种型号,利用恒温恒湿箱进行纸张变形实验,在各设定温湿度条件下,分别测量吸湿和脱湿过程中大号纸张尺寸和小号纸张的含水量。首先通过环境湿度与纸张尺寸的相关性进行建模分析,获得相对湿度为55%的条件下纸张的标准尺寸,以此计算纸张的伸缩率;其次根据参考套印精度范围计算纸张的伸缩率范围,通过构建纸张伸缩率与湿度关联模型获得湿度范围;然后建立含水量与环境温湿度的关联模型,通过纸张伸缩率与含水量的相关性分析,将湿度范围应用到含水量模型中,最终获得参考套印精度对应的温度范围。结果研究结果表明,在同时满足3种纸张套印精度控制范围条件下,车间温度标准控制范围应为20.4~26.3℃,车间相对湿度标准控制范围应为53.9%~58.0%。结论通过研究环境温湿度对镀铝纸变形的影响,使镀铝纸变形得到良好控制。
The work aims to explore the influence of environmental temperature and humidity on deformation of aluminized paper, and obtain the best ranges of storage temperature and humidity of the aluminized paper. Three kinds of aluminized papers were respectively cut into two different sizes, and the paper deformation experiments were carried out by constant temperature humidity chamber. In each setting conditions of temperature and humidity, the sizes of large paper and moisture content of small paper were respectively measured in the process of moisture absorption and dehumidification. First, in order to calculate the paper stretch ratio, the standard paper sizes were obtained in 55%RH conditions through the correlation modeling analysis of environmental humidity and paper size. Second, the range of paper stretch ratio was calculated according to the range of referenced registering accuracy. The humidity range was achieved through constructing the correlation model of paper stretch ratio and humidity. Third, the correlation model was established between water content and environmental temperature and humidity. Finally, through the correlation analysis of paper stretch ratio and water content, the temperature range corresponding to the referenced registering accuracy was gained by applying the humidity range to the water content model. The research results showed that, under the conditions of meeting the control range of registering accuracy of three kinds of papers, the standard control range of the workshop temperature should be 20.4~26.3 ℃, and the standard control range of relative humidity of the workshop should be 53.9%~58.0%. The deformation of aluminized paper can be well controlled through the study on the influence of environmental temperature and humidity on the deformation of aluminized paper.
