我们都知道，油画是用快干性的植物油调和颜料，在亚麻布、纸板或木板上进行制作的一个画种，收购名人字画作画时使用的稀释剂为挥发性的松节油和干性的亚麻仁油等。画面所附着的颜料有较强的硬度，当画面干燥后，能长期保持光泽。但是在收藏保存时也需注意以下几点：
We all know that the painting is fast dry vegetable oil paint, making a kind of painting on the linen cloth, cardboard or wood, the use of the acquisition of celebrity calligraphy and painting when painting as the diluent of volatile oil of turpentine and dry linseed oil. The pigment attached to the screen has a strong hardness, and can keep luster for a long time when the screen is dry. However, we should pay attention to the following points in the collection and preservation:


1、定期清洁：油画的清洁做法其实很简单，准备个软毛刷或是羊毛笔，固定一个顺势轻轻刷除表面附着的灰尘即可。油画作品背后的框架下缘内侧，是比较容易被忽略的但却是重要的，灰尘的囤积会吸收湿气，接着湿气会被画布纤维吸收，久了背面便会产生水渍甚是一道水纹，如果严重了会引起作品正面的颜料层变色、脱胶、起甲以及剥落等状况，所以定时取下作品清洁背后的灰尘是必要的。
1, regular cleaning: oil painting cleaning practice is actually very simple, prepare a soft brush or a wool pen, fixed a homeopathic brush gently, except the surface of the dust can be attached. Frame behind the lower edge of the paintings inside, is easily overlooked but it is the most important, the dust absorbs moisture and moisture accumulation, will be the canvas fiber absorption, long back will produce water or a water, if serious works will cause positive discoloration, degumming, pigment layer from a condition of dust and peeling, so take the timing behind clean works is necessary.
2、选择适当位置：作品悬挂的地方应该要避开浴室、厨房，尽量不要靠近水分较多或湿气较重的地方，尤其悬挂的墙面也要仔细考虑，墙面里不要有水管埋藏。
2, select the appropriate location: the work place should avoid hanging bathroom, kitchen, try not to close more water or moisture heavier, especially hanging wall has to be carefully considered, not buried pipe wall.
3、避免阳光直射：阳光的紫外线其实是无形的杀手，尤其对某些特定的颜料，例如锌白、柠檬黄等，这类颜料在紫外线的强照下会严重褪色甚消失。而紫外线对画面也会产生其他影响，严重的甚会造成颜色粉化。
3, avoid direct sunlight, the sun's ultraviolet rays are invisible killer, especially for certain pigments, such as white, lemon yellow, will seriously fade or even disappear this kind of pigment in the ultraviolet irradiation intensity. Ultraviolet light also has other effects on the screen, which can even cause color to be pulverized.
4、保持通风：油画怕的就是潮湿，潮湿所衍生的问题很多，当湿气积累于基底材的画布纤维中会导致画布膨胀，而干燥时又会使画布收缩，如此长时间的一胀一缩便会造成附着于画布上的颜料层起甲、剥离、脱落以及龟裂、变色等，而湿气若积久不散便容易长霉。尽量不要加装玻璃或亚克力，不但不易散发湿气也容易助于霉菌生长。
4, maintain ventilation: oil painting is the most humid and humid, derived a lot of problems, when the moisture accumulation in the basal material of canvas fiber will lead to canvas expansion, when it is dry and will make such an expansion and contraction of the canvas, a long time will cause shrinkage of pigment layer on the canvas of a play and debonding and cracking, discoloration, and moisture or not if it is easy to mildew powder. Try not to add glass or acrylic, not only not easy to emit moisture, but also easy to mold growth.
