直接的濕度概念是指一定量的空氣氣中水蒸氣的含量，相對濕度對字畫的影響主要表現(xiàn)在以下三個方面，
濟南收購字畫人員為您分析。
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.引起變形
1. Cause deformation
空氣濕度大,而且氣溫相對較高時，古書畫文物的紙張和綾絹絲織品等材料在這種情況下就可能因為吸水或脫水而發(fā)生形變,并產(chǎn)生應(yīng)力,從而給古書畫的保存帶來影響。
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.
古書畫所用紙張、綾絹都是纖維狀物質(zhì),有著很強的吸水能力,它們不但可以在同其他含水材料接觸式吸收水分,而且還從潮濕空氣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,它們還有直接向干燥空氣中排水的能力。紙張和綾絹吸水后膨脹,各個方向上的直線尺寸和面積都會增加,而當(dāng)它們脫水時各個方向.上的直線尺寸和面積都會縮小,這些變化都是干濕度改變引|起的塑性形變。
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.發(fā)生化學(xué)反應(yīng)
2. Chemical reaction occurs
古書畫、文物等在高溫高濕的天氣中,其表面所涂抹的繪畫顏料和其他添加物會很容易分解變色,對古書畫的保存影響很壞。繪畫所選的顏料以及墨汁當(dāng)中的膠,在長時間處于潮濕環(huán)境時,他們當(dāng)中的主要成分膠原蛋白會被很大程度的分解而變質(zhì)從而失去粘性,而當(dāng)顏料和墨汁在失去粘性的條件下,就很容易從畫面上脫落,這樣畫面上的色彩就會流失,影響書畫藝術(shù)的壽命和價值。
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|起生物腐蝕
3. Bow | biological corrosion
當(dāng)空氣中大氣的溫度很低時。古書畫的卷面上就會出現(xiàn)露水現(xiàn)象,也就是當(dāng)古書畫周圍的空溫度很低時,周圍空氣中的水蒸氣會越積越多而形成水珠吸附于古書畫表面,而由于凝結(jié)的水珠大小不同,古書畫的材質(zhì)吸附水珠的多少有不同而造成古書畫出現(xiàn)荷葉邊現(xiàn)象,給其帶來很大的損害。
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.lebigueone.com ！
