名人字畫是非常具有收藏價值的，而且收藏價值越高的字畫越具有升值的空間。但是如果在收藏時不注意的話就會對字畫有影響，降低其價值。那么危害名人字畫的因素有哪些呢？下面小編給大家介紹下。
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
光是對名人字畫影響的自然因素，特別是紫外光，它可使畫面顏料蛻變、分解，導致紙質變化。紫外光主要來自太陽光，白熾燈泡和熒光燈管發出的光也有少量紫外光。因此，在掛畫時，不能靠近窗戶，避免太陽光直接照射畫面。燈泡或日光燈發出400--700nm(納米)可見長，雖說影響不大，但長時間近距離照射也能使名人字畫紙質變黃。
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、塵埃
2. Dust
塵埃吸附有害氣體，懸浮于空氣中，日久天長沉積在畫面上，會侵蝕畫面。一般說，城市環境一周除一次塵，鄉村環境一月除一次塵。除塵方法:可用電吹風的冷風與畫面成30度角，保持10--15厘米的距離從右到左掃一遍，或者用雞毛撣輕輕掃一下畫面。
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、蠹魚
3. Codfish
也稱衣魚、紙魚，是無翅昆蟲，一般蛀食書畫表面，特別危害糨糊粘貼處。煙草甲的幼蟲對書畫危害很大，喜歡在書畫中打洞，而自身藏于洞內。一般書畫防蟲多用驅避劑，常用的藥物如衛生球、樟腦丸、對二氯化苯，這種藥品都是白色固體，易于揮發。
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.
說到昆蟲，因為夏季多雨，空氣濕度大，字畫易遭受霉菌侵蝕，潮濕的空氣會改變紙、絹等的物理結構，此時較好將書畫作品卷收起來，放到窄小的木匣中或者塑料袋中封閉起來，以免受潮發霉。另外在放置的袋中也可放些樟腦丸之類的防蟲藥品，以防止生蠹蟲。
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.
山東收購名人字畫收藏者提醒，如果字畫已經受潮，可將受潮輕的作品擺放到鋪有氈子的平案上，將室內溫度調22℃25℃慢慢晾干；對受潮較為嚴重的或被雨水淋濕的作品，則要考慮重新揭裱，對作品上所留下的斑漬進行清洗，還作品本來面目。
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.
