直接的湿度概念是指一定量的空气气中水蒸气的含量，相对湿度对字画的影响主要表现在以下三个方面，
济南收购字画人员为您分析。
The concept of direct humidity refers to the content of water vapor in a certain amount of air. The impact of relative humidity on calligraphy and painting is mainly shown in the following three aspects. Jinan's calligraphy and painting personnel will analyze it for you.
1.引起变形
1. Cause deformation
空气湿度大,而且气温相对较高时，古书画文物的纸张和绫绢丝织品等材料在这种情况下就可能因为吸水或脱水而发生形变,并产生应力,从而给古书画的保存带来影响。
When the air humidity is high and the temperature is relatively high, the paper, silk and silk fabrics and other materials of ancient calligraphy and painting relics may be deformed and generate stress due to water absorption or dehydration, thus affecting the preservation of ancient calligraphy and painting.
古书画所用纸张、绫绢都是纤维状物质,有着很强的吸水能力,它们不但可以在同其他含水材料接触式吸收水分,而且还从潮湿空气中直接吸收水分的能力。
The paper and silk used in ancient calligraphy and painting are all fibrous materials with strong water absorption capacity. They can not only absorb water in contact with other water containing materials, but also directly absorb water from moist air.
另外,它们还有直接向干燥空气中排水的能力。纸张和绫绢吸水后膨胀,各个方向上的直线尺寸和面积都会增加,而当它们脱水时各个方向.上的直线尺寸和面积都会缩小,这些变化都是干湿度改变引|起的塑性形变。
In addition, they have the ability to drain water directly into dry air. Paper and silk will swell after absorbing water, and the linear size and area in all directions will increase. When they are dehydrated, the linear size and area in all directions will decrease. These changes are plastic deformation caused by changes in humidity and dryness.
2.发生化学反应
2. Chemical reaction occurs
古书画、文物等在高温高湿的天气中,其表面所涂抹的绘画颜料和其他添加物会很容易分解变色,对古书画的保存影响很坏。绘画所选的颜料以及墨汁当中的胶,在长时间处于潮湿环境时,他们当中的主要成分胶原蛋白会被很大程度的分解而变质从而失去粘性,而当颜料和墨汁在失去粘性的条件下,就很容易从画面上脱落,这样画面上的色彩就会流失,影响书画艺术的寿命和价值。
In the hot and humid weather, the painting pigments and other additives on the surface of ancient calligraphy, painting and cultural relics can easily decompose and discolor, which has a bad impact on the preservation of ancient calligraphy and painting. The pigment selected for painting and the glue in the ink will be degraded to a large extent and lose its stickiness when they are in a humid environment for a long time. When the pigment and ink lose their stickiness, they will easily fall off from the screen, so that the color on the screen will be lost, affecting the life and value of calligraphy and painting art.
3.弓|起生物腐蚀
3. Bow | biological corrosion
当空气中大气的温度很低时。古书画的卷面上就会出现露水现象,也就是当古书画周围的空温度很低时,周围空气中的水蒸气会越积越多而形成水珠吸附于古书画表面,而由于凝结的水珠大小不同,古书画的材质吸附水珠的多少有不同而造成古书画出现荷叶边现象,给其带来很大的损害。
When the temperature of the atmosphere in the air is very low. Dew will appear on the roll surface of ancient calligraphy and painting, that is, when the temperature of the air around ancient calligraphy and painting is very low, the water vapor in the surrounding air will accumulate more and more and form water drops to adsorb on the surface of ancient calligraphy and painting. Due to the different size of condensed water drops, the material of ancient calligraphy and painting adsorbs water drops differently, which causes the lotus leaf phenomenon of ancient calligraphy and painting, bringing great damage to them.
For the influence of relative humidity on calligraphy and painting, we have covered three aspects. If you have any questions, please contact us at any time http://www.jinandayatang.com ！
