Cultural relics due to a variety of environmental and storage time and other reasons. The surface will have a lot of dirt, such as: dirt spots, rust spots, oil, water stains, sweat stains, etc., due to the many types of artifacts, different textures, in the cleaning and processing methods taken are different. This has brought a lot of inconvenience to the cleaning of cultural relics. Here we look at the traditional way of cleaning cultural relics what are?
Traditional cleaning treatment generally has the following ways:
First, water washing
For general solid texture, not afraid of water immersion artifacts, such as: pottery, porcelain, brick, tile, stone, copper, iron, bone, tooth, jade, wood and other materials made of cultural relics and antiques, the surface attached or stained dirt can be washed with distilled water.
Second, dry cleaning
Textile relics such as stains, water washing may fade, then you should use gasoline and other things to scrub, you can also use dry cleaning agent sprayed directly on the stain, dry cleaning agent should be used before a test. Dry cleaning is best to start from inconspicuous places or corner parts, and finally deal with the center of the tissue or obvious parts.
Third, dry cleaning
Some artifacts that are afraid of water and some excavated items, in order to maintain the natural color of the original artifacts due to long years of ground erosion, should not be rinsed with water and drugs. For this type of artifacts with a loose texture of the tide cloth can be gently wiped.
Four, wind drying
For the paper items and some fabrics that should not be washed or dry-rubbed, you should choose the wind-drying method to blow away the dust and moisture on its surface. When drying outdoors should pay attention to weather changes, to avoid prolonged exposure to strong sunlight, avoid stronger wind blowing, and keep track of temperature and humidity changes. Also avoid smoke pollution near the chimney, under the tree to prevent birds and insects damage, but also avoid the willow flowering season for wind drying to prevent pollen staining and so on.
Five, mechanical dust removal
For larger, bulky and irregular objects, such as furniture, carpets, hollow body objects, etc., can use mechanical dust removal such as vacuum cleaners; for larger stone carvings, sculptures, etc., in the vacuum at the same time can also use high-pressure air pump, the vacuum cleaner is not easy to remove the dust blown off.
Sixth, drug cleaning
Mainly used in various types of harsh environment preservation of antiques and excavated cultural relics. These artifacts buried in the ground for a long time, by a variety of environmental and harmful substances, rust and corrosion serious. Because of the different mixes in excavated objects around the corrosion varies, so in the use of self-contained liquid should first do experiments, to obtain obvious results before use; to be different for each artifact, the choice of different drugs and use different methods.
The above-mentioned six cleaning means will cause irreversible damage to cultural relics, just how much damage is the problem. And laser heritage cleaning is different, laser cleaning using the characteristics of the laser beam, through the spotting system can make the laser beam gathered into different sizes of spot diameter, under the same conditions of laser energy, different spots of the laser beam, the energy density or power density generated is different, so that it is convenient to control the laser energy required for cleaning. Laser can achieve a high degree of concentration in time and space. Laser cleaning is the use of these characteristics to effectively remove the contaminants. So that the contaminants are instantly stripped from the surface of the cultural relics, thus achieving the cleaning of cultural relics.
Another important aspect: it is a harmless way of cleaning - the surface of the cultural relics and the adherence of its contaminants on the laser beam absorption is different, this difference allows people to distinguish between the contaminants and the surface material of cultural relics, so as to precisely control the laser energy required for cleaning, so as not to harm cultural relics, but also to remove the contaminants. This technology has been widely used in stone relics, oil paintings and other fields.
Laser cleaning equipment is a new generation of high-tech products of the surface, easy to install, manipulate and achieve automation. Simple operation, turn on the electricity, open the equipment, you can carry out no chemical reagents, no media, no dust, no water cleaning, automatic focus, fit the surface cleaning, cleaning surface cleanliness and other advantages, can remove the object surface resin, oil, stains, dirt, embroidery, coating, plating, paint.
