书画，是精美的艺术品，必须有一定时间的挂或殿。藏于箱底秘不示人的做法是不可取的，因为书画慢慢进行的潜在变化人们不能及时得知。等发现问题己为时太晚。所以，对装裱以后的书画都要间隔地挂展一段时间。

Calligraphy and painting are exquisite works of art that must have been hung or decorated for a certain period of time. It is not advisable to keep it hidden at the bottom of the box, as potential changes in calligraphy and painting may not be known in a timely manner. It's too late to discover the problem. So, for the mounted calligraphy and paintings, they should be hung and displayed at intervals for a period of time.

高价收购名人字画人员建议在挂展期间，要注意及时除尘，因为现在的环境污染比较严重。尘埃吸附这些有害气体，悬浮于空气中，日久天长沉积在画面上，就会侵蚀画面。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。

It is recommended that personnel who purchase celebrity calligraphy and painting at a high price should pay attention to timely dust removal during the exhibition period, as the current environmental pollution is relatively serious. Dust adsorbs these harmful gases, suspends them in the air, and over time deposits on the image, which will erode it. Generally speaking, urban environments are dusted once a week, and rural environments are dusted once a month. Dust removal method: Use the cold air of an electric hair dryer to form a 30 degree angle with the image, maintain a distance of 10-15 centimeters, and sweep it from right to left, or use a feather duster to gently sweep the image.

或用开到低风档的吸尘器一边用软毛刷扫画面，一边用吸尘器吸尘。不可用抹布一类东西去擦画面，因为这样，有害尘埃会在擦的过程中侵入画面纸张的纹里，造成长期的损害。展、挂期间，要注意空气的湿度，若遇阴雨连绵，空气湿度特别大，可以先把字画卷收起来。人为改变小空间环境，如加热取暖，加湿加香，都要倍加注意。冬天取暖，书画要与暖气、烟筒保持一定距离，夏日制冷，要与空调的进气口保持较远距离。

Alternatively, use a vacuum cleaner with a low wind speed to sweep the screen with a soft bristle brush while vacuuming. Do not use a cloth or other object to wipe the image, as harmful dust can invade the grain of the paper during the wiping process, causing long-term damage. During the exhibition and hanging period, pay attention to the humidity of the air. If there is continuous rain and the humidity is particularly high, you can roll up the calligraphy and painting first. People should pay extra attention to changing the environment of small spaces, such as heating, humidification, and fragrance. In winter, for heating, calligraphy and painting should be kept at a certain distance from the heating system and chimney. In summer, for cooling, it should be kept at a relatively long distance from the air inlet of the air conditioner.

光是对画影响大的自然因素，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。

Light is a natural factor that has a significant impact on painting, especially ultraviolet light, which can cause the paint on the screen to transform and decompose, leading to changes in the paper. Ultraviolet light mainly comes from sunlight, and there is also a small amount of ultraviolet light emitted by incandescent bulbs and fluorescent tubes. Therefore, when hanging pictures, do not approach the window to avoid direct sunlight on the screen.

灯泡或日光灯发出400一一700nm(纳米)可见长,虽说影响不大，但长时间近距离照射也能使字画纸质变黄。所以，在房子布局安排上，应该让灯泡，日光灯与书画保持1米以上的距离。 并选用低功率灯光源。还有什么问题就来我们网站https://www.jndyt888.com咨询吧！

A light bulb or fluorescent lamp emits a visible length of 400-700nm (nanometers), although the effect is not significant, prolonged close exposure can also cause calligraphy and painting paper to turn yellow. So, in the layout of the house, the distance between light bulbs, fluorescent lights, and calligraphy and painting should be kept at least 1 meter. And choose low-power light sources.
