1, preservation of scientific and technological archives
The preservation of scientific and technological archives is a business work of scientific and technological archives, which is to create suitable conditions and environment for the preservation of scientific and technological archives, properly protect scientific and technological archives, and establish and maintain a good order for the preservation of scientific and technological archives.

3, science and technology archives storage conditions and protection measures
4, science and technology archives storage methods and requirements
① Preservation of basemap files
The base map has the function of copying, and special raw materials and technological measures are used, which is not conducive to the durability of the base map. It is forbidden to fold the base map, and it should be stored in a special base map cabinet.
Storage method:
One is flat, that is, the base map is placed flat in the base map cabinet of multi-layer drawers in order of arrangement, which is a better storage method.
The second is rolling, that is, the base map is put in the base map cabinet with a sleeve or rolled into a tube, which is inconvenient to take and put, and will increase the wear and tear of the base map. It is best to roll the super-large format base map.
In short, we should try our best to ensure that the base map will not be torn, folded, squeezed or worn.
② Preservation of blueprints and copies.
Photocopys such as blueprints are made of materials with good mechanical strength, especially blueprints of different sizes, which should be saved by folding and rolling.
The blueprint is folded into A4 drawing format in accordion style. Display the title in the lower right corner when folding for easy reference. If binding is required, the binding line should be left blank. After folding, save it in a file box.
③ Storage of photosensitive materials
The photosensitive materials in scientific and technological archives mainly include negatives (films) and photos, among which the preservation of negatives is more important, because negatives are master films, and once they are damaged, photos cannot be made.
Specific methods:
1, sealed and stored in a heat-insulated and sealed container.
2. The negative plane should be perpendicular to the horizontal plane.
3. Negative films should be stored in different categories, such as master films and reproductions, permanent preservation and non-permanent preservation.
4, check once every one to two years, found abnormal should be handled.
5, storage conditions, temperature 13 ~ 15℃, temperature 35%-45%, color should be below 2℃.
④ Preservation of magnetic materials
Magnetic materials mainly refer to video tapes, audio tapes and machine-readable documents.
The main storage methods are:
1, anti-magnetic, put the tape in a metal cabinet, away from the magnetic field, and there should be no electrical equipment such as transformers, motors and televisions around. ?
2, the tape should be flat, don't overlap too much.
3, regular inspection, tape rewind once every 6- 12 months, found that the problem should be transcribed in time, machine-readable files are copied once every 3-5 years.
4. The tapes that have not been used for a long time are wound with magnetic isolation materials to prevent the tapes from magnetizing each other.
⑤ Management of science and technology archives warehouse
A warehouse is a place where scientific and technological files are kept. In order to make rational use of the warehouse area, facilitate the storage and search of scientific and technological archives, and improve the efficiency of scientific and technological archives work, warehouse management should be strengthened.
Location management:
The spatial location where scientific and technological files are stored is called warehouse location. The task of warehouse location management is to plan the use area and the number of shelves of the warehouse and rationally arrange the warehouse, so as to implement the location management of scientific and technological archives.
Shelf layout:
Cabinet rack is the equipment and accessories for storing documents in the warehouse. The following requirements shall be observed:
1, all kinds of cabinets should be classified and centralized.
2. The bent should be perpendicular to the window and keep a certain distance from the wall to prevent direct sunlight and avoid the direct influence of external temperature and humidity on the archives.
3. The channel between cabinets should be kept 0.9m- 1.2m wide, which is convenient for management and traffic and makes full use of the warehouse area. ?
4. The partition or drawer of each bookshelf should indicate the category and file number of scientific and technological files.
5, for the use of dense rack equipment, should fully consider the load of the warehouse building.
File shelving:
According to the predetermined shelving method, the scientific and technological files will be put on the shelves, put in and out of the warehouse, and managed by positioning.
Shelving methods are:
(1) The water shelving method can be divided into large water shelving and small water shelving (classified water shelving). Large water is mixed and arranged in the order of storage, regardless of type and category. Small water bent (classified water bent) should be implemented in different categories, such as product files, equipment files, scientific research files, infrastructure files, etc. , and then shelved in the order of receipt, or separated by year, and then implemented during the year.
(2) The classification shelving method is based on the classification of scientific and technological archives, and then arranged according to the category, project and documents within the project.
According to the predetermined shelving method, the scientific and technological files will be put on the shelves, put in and out of the warehouse, and managed by positioning.
Shelf requirements:
(1) From bottom to bottom, from left to right for easy management. ?
(2) Maintain proper saturation. Overcrowding increases the friction of files, and the structure affects the utilization rate of positions.
Warehouse management:
The inventory of scientific and technological archives is always in a state of flow and change, so it is necessary to know the borrowing quantity, lending situation, demolition situation, sealing situation and destruction situation of scientific and technological archives in time.
Second, the science and technology archives storage system
The scientific and technological archives preservation system is the basis and control means to complete the task of scientific and technological archives preservation, and it is also an integral part of the archives management system. Mainly includes:
