The first is pest control. The main pests that destroy cultural relics are Bemisia tabaci, sweater fish, bark beetles, termites, rice flour insects and so on. Not only do they eat paper, but the liquid they secrete and the stains they discharge will also seriously damage the paper.
There are several methods of pest control, such as dipping, which is to soak paper in a plant solution with insecticidal effect and then take it out to dry. There is also the odor drive method, which is to put drugs with certain venom and pungent odor such as musk, papaya, rut and camphor into boxes, cabinets and cabinets for storing paper. Modern chemicals can also be used to prevent and kill insects.
The second is to prevent and control rodents. The harm of rats to paper can not be ignored, and the most effective way to prevent rats is to kill them.
The third is to prevent mildew. The specific method is the addition method, that is, the mildewproof agent is prepared according to a certain proportion and added to the paste or emulsion coating to make the mildewproof coating. Spray method, that is, the mildew inhibitor is prepared into solution and sprayed on paper cultural relics. Adsorption method, that is, the mildew inhibitor is made into tablets or powder, so that it slowly volatilizes. Immersion method, that is, a certain specification of kraft paper and white paper are soaked in a mildew-proof solution, dried in the shade and sandwiched in ancient paper or paper cultural relics, and can also be used for packaging paper cultural relics.
In addition, to maintain ancient paper or paper cultural relics, we need to do a good job of dust prevention, harmful gas prevention, light protection, etc. These are aspects that we can't ignore in the process of maintaining paper.
