名人字画是非常具有收藏价值的，而且收藏价值越高的字画越具有升值的空间。但是如果在收藏时不注意的话就会对字画有影响，降低其价值。那么危害名人字画的因素有哪些呢？下面小编给大家介绍下。
Celebrity calligraphy and paintings are of great collection value, and the higher the collection value, the more room for appreciation. But if you don't pay attention when collecting, it will have an impact on calligraphy and painting and reduce its value. So what are the factors that endanger celebrity calligraphy and painting? Let's introduce it to you.
1、光
1. Light
光是对名人字画影响的自然因素，特别是紫外光，它可使画面颜料蜕变、分解，导致纸质变化。紫外光主要来自太阳光，白炽灯泡和荧光灯管发出的光也有少量紫外光。因此，在挂画时，不能靠近窗户，避免太阳光直接照射画面。灯泡或日光灯发出400--700nm(纳米)可见长，虽说影响不大，但长时间近距离照射也能使名人字画纸质变黄。
Light is a natural factor that affects the calligraphy and painting of celebrities, especially ultraviolet light, which can make the paint of the picture degenerate and decompose, resulting in the change of paper. Ultraviolet light mainly comes from the sun, and the light emitted by incandescent bulbs and fluorescent tubes also has a small amount of ultraviolet light. Therefore, when hanging pictures, do not close to the window to avoid direct sunlight on the picture. The light bulb or fluorescent lamp emits a visible length of 400--700nm (nm). Although it has little effect, long-time close-up irradiation can also make the paper of celebrity calligraphy and painting turn yellow.
2、尘埃
2. Dust
尘埃吸附有害气体，悬浮于空气中，日久天长沉积在画面上，会侵蚀画面。一般说，城市环境一周除一次尘，乡村环境一月除一次尘。除尘方法:可用电吹风的冷风与画面成30度角，保持10--15厘米的距离从右到左扫一遍，或者用鸡毛掸轻轻扫一下画面。
Dust adsorbs harmful gas, which is suspended in the air and deposited on the picture over time, which will erode the picture. Generally speaking, the dust is removed once a week in urban environment and once a month in rural environment. Dust removal method: use the cold air of the hair dryer to form a 30 degree angle with the picture, and keep a distance of 10-15 cm from right to left, or use a feather duster to gently sweep the picture.
3、蠹鱼
3. Codfish
也称衣鱼、纸鱼，是无翅昆虫，一般蛀食书画表面，特别危害糨糊粘贴处。烟草甲的幼虫对书画危害很大，喜欢在书画中打洞，而自身藏于洞内。一般书画防虫多用驱避剂，常用的药物如卫生球、樟脑丸、对二氯化苯，这种药品都是白色固体，易于挥发。
Also known as clothes fish and paper fish, they are wingless insects. They generally eat the surface of calligraphy and painting, especially the paste paste. The larva of tobacco beetle is very harmful to calligraphy and painting. It likes to make holes in calligraphy and painting and hides itself in the holes. Generally, insect repellents are used in calligraphy and painting. Commonly used drugs such as sanitary balls, camphor pills and p-dichlorobenzene are white solids and easy to volatilize.
说到昆虫，因为夏季多雨，空气湿度大，字画易遭受霉菌侵蚀，潮湿的空气会改变纸、绢等的物理结构，此时较好将书画作品卷收起来，放到窄小的木匣中或者塑料袋中封闭起来，以免受潮发霉。另外在放置的袋中也可放些樟脑丸之类的防虫药品，以防止生蠹虫。
When it comes to insects, because it is rainy in summer, the air humidity is high, and calligraphy and painting are vulnerable to mold erosion. The humid air will change the physical structure of paper, silk, etc. at this time, it is better to roll up the calligraphy and painting works and put them in narrow wooden boxes or plastic bags to prevent them from becoming damp and moldy. In addition, some moth proofing drugs such as camphor pills can be put in the placed bag to prevent the birth of beetles.

Shandong's famous calligraphy and painting collectors remind that if the calligraphy and painting have been damped, the lightly damped works can be placed on the flat table covered with felt, and the indoor temperature can be adjusted to 22 ℃ to 25 ℃ to dry slowly; For works that are seriously damped or wetted by rain, it is necessary to consider re framing, cleaning the spots and stains left on the works, and returning the works to their true colors.
