Warehouse custodians should master the performance, characteristics, validity period, storage methods, and precautions and requirements of all warehousing materials. Seriously do a good job of moisture, mold, dust, rust, heat, fire, sun, and deterrence of materials, to prevent confusion of varieties, specifications and quality performance. For the storage of goods must be in accordance with the type, name, specifications, batches, quantities, timely registration and do a good job, pay, deposit account records, so that the same card accounts.
Storage of base paper
The base paper is the main material for the production of corrugated cartons, and it is a kind of easily damaged material because of many transportation and loading and unloading processes. If you are careless in the process of loading and unloading, it will cause great losses, so the loading and unloading and handling of the base paper , storage and storage should pay attention to the following aspects:
1. During the loading and unloading process of the web, the outer layer of the web must be prevented from being damaged, resulting in a higher reject rate of the base paper and the single-faced corrugated cardboard when the machine is used. When storing, it is better to place the roll vertically and hold it in place. Hoop forklift loading and unloading. Especially when holding a forklift, you can install a large iron plate on the fork of an ordinary forklift. The front of the iron plate should be thin, and the fork should be slowly inserted from the side of the reel. It is better to roll the plate onto the right-hand plate. Can not be forked from the end surface, but not on the side or end of the fork on the paper, when placed, but also put the low head first, so that roll gently roll, can not be thrown to prevent the roll from the paper The car - fell and fell flat.
2. During the loading and unloading process of the flatbed paper, the loading and unloading tools are used to smoothly remove the flatbed paper, and the splint cannot be dropped from the car to prevent the folding and influencing the use and causing the defective product to be scrapped. put. Whiteboard paper used for color printing, should pay attention to the conditions of paper storage when storing, control the temperature and humidity of the warehouse environment, if the paper is stored under high humidity conditions, it will absorb the surrounding moisture and roll the mountain I deformation, the emergence of Foliage; if the paper is stored in a very dry environment, it will cause the water in the paper to disperse, making the paper brittle, brittle, and tight edges. Therefore, the paper should be stored near the use of the environment, so that the moisture content of the paper and the production environment to maintain a balance, to meet the production process requirements.
3. To place the base paper in a dry place, do not allow the base paper to get damp, let alone allow the base paper to get wet with rain. Should be divided according to different species and specifications of the area for storage, at the same time to hang a good identification card.
4. The company's accounts were carefully established for the name, specifications, quantity, supplier, factory quantity, factory time, storage location, and inspection quality of the incoming raw paper.
5. The floor of the warehouse where the base paper is stored shall not contain any hard objects such as gravel, brick slag, and scrap iron, and the ground must be kept clean. It prevents gravel, brick slag, broken iron and other hard objects from being pressed into the base paper, resulting in damage to the base paper and equipment wear.
6. When used, the manufactory of the base paper has to be used one after the other, which is the first use of the ancestral plant, and the later use of the factory.
7. The base paper is flammable and fire prevention work must be done.
8. At the end of each month, inventory of the stock base paper should be carried out once. It is very easy to understand how to minimize the inventory overstock so as not to occupy too much money.
Storage of accessories
1. The storage location of the starch should be kept clean, ventilated and dry, cool, weathering, rain, and no fire. Do not stack with poisonous, corrosive and odor-bearing items. Product packaging bags should be stacked on the backing plate over 100mln from the ground. The stacking should be away from the wall 5 () 0mm. Easy access.
Starch packaging bags must be strong in bags, clean and tidy, well-sealed in the mouth, and particularly leaky and damp during transportation. Handle with care when loading and unloading. It is forbidden to directly use the hooking bag.
2. Caustic soda. Caustic soda has solid, flake and liquid components. Currently, caustic soda is used more in the carton industry. Solid caustic soda and caustic soda must be well protected from moisture and moisture during storage and storage. Otherwise, in wet conditions, solid caustic soda and protopine will absorb moisture. In addition, caustic soda is very corrosive. When accidentally splashed on the eyes and skin, rinse it thoroughly with clean water.
3. Borax. Packaged borax should be protected from rain or moisture, and should not be mixed with moisture and other colored materials. It should be stored in a dry and clean warehouse.
4. Hydrogen peroxide is a strong oxidant, although it will not burn itself, but it will cause violent reaction and burning when in contact with flammable and raw materials. It has strong irritation to human skin. When hydrogen peroxide is exposed to heat or sun exposure, it will decompose even Explosion, in the case of alkaline substances, no matter what the humidity is quickly oxygen. Store and transport must be sealed, to be stored in a cool, dark and ventilated place, to prevent decomposition of light, light handling when handling, long storage will reduce its composition, it should not be stored too long. Acetylaniline may be added in small amounts, and acetyltetanylaniline may be used as a stabilizer.
5. The nail box flat tape should not be stored together with corrosive and oxidizing substances, and should be placed in a dry place to avoid damp dust rust.
6. Flexible version of the plate - set to avoid light preservation, anti 11: mouth light and ultraviolet light irradiation, or after the door light and ultraviolet light irradiation, serious will make the flexible version of the photosensitive material polymerization led to the plate scrap, light The person will cause the depth and depth of the pattern, text, and line; enough. In addition, do not place in places with ozone, arcs, and organic chemical solvents to prevent denaturation of the resin plate.
7. Double-sided pressure-sensitive adhesive tapes are not allowed to be stored with scorpions. Contact with organic solvents, etc., should be placed in a dry warehouse, one meter away from the heat source.
8. Solvent-based moisture-proof agent must be sealed during storage to prevent volatilization, pay attention to fire prevention, to be stored in the cool and cool phlegm: dry soil, use, stir evenly. Water-soluble and moisture-proof agents must be kept in sealed storage to prevent evaporation, and they should be stored in a cool, dry place to prevent the sun from getting out of the rain. In the winter, they should be kept in an environment with a temperature above 10°C to prevent flocculation. Stir before use. Shelf life is generally about 6 months.
9. Polypropylene tying ropes should be stacked in a dry, clean, cool and cool warehouse. They must not be near fire or heat sources, and should be kept intact. The storage period should not exceed one year from the date of manufacture.
10. The plastic-based pressure-sensitive adhesive tape (water-free tape) is stored magnetically in a cool, dry warehouse, and there should be a backing plate on the ground. There should be a certain distance from the wall to prevent direct sunlight and away from steam pipes, radiators or other heat sources. Corrosive substances.
11. Storage of equipment spare parts. A detailed record of the quantities, specifications, models, and purchase times must be made for purchased machinery and equipment. According to specifications, models, manufacturers, purchase time, number of buyers classified storage, and to do a good job of spare parts rust, dust, classification, positioning, identification, identification, distribution, records and other items of custody.
