What are the measures to prevent rust in the storage of metal products? Let's analyze it together.
Metal products are easy to rust, so storage is very important. What should be paid attention to in the storage of metal products, let's take a look at several measures to prevent rust in the storage of metal products.
keep warehouse dry
Generally speaking, the relative humidity of the warehouse should be controlled at about 70%, and do not allow moisture to condense on the surface of the interest rate material. In general, opening windows for proper ventilation can be done, but not on cloudy days.
2. Protect the protective layer or packaging of metal products from damage
In order to prevent metal materials from rusting, some metal materials in the factory are coated with preservatives, electroplated or packaged. These protective layers need to be protected to prevent damage to the outer layer and packaging during all operations such as handling, loading and unloading, stacking, tamping, and avoid scratching the material itself. If the package is damaged, it should be repaired and sturdy. When it cannot be repaired, the package can be replaced. The moisture of the package should be wiped clean. If the original factory oiled material is found to be contaminated, the floor is rusted or volatilized, it is necessary to remove the dirt and re-oil it.
3. Maintain the clearing method
Custody rate materials need to be kept clean. In particular, the shipping materials should be wiped clean to avoid rusting after seawater or dirt. Sweaty hands are also prone to rust, so try to avoid hand-processed metal products and materials such as sickles and bikui. Do not use wood chips, wood shoulders, broken skins and other debris on metal materials. Pay attention to cleanliness during storage to avoid contamination of materials and adhesion of dust and debris.
4. Strengthen arrests and deal with them in a timely manner
During the storage period of metal materials, various inspections of regular, regular, irregular, seasonal and temporary should be carried out, and problems should be found and dealt with in time.
5. Implement the principle of "first-in, first-out, replacement out of the warehouse".
Various anti-corrosion measures for metal materials can only play a role in preventing corrosion, so the storage must have a certain period of time.
7. Choose an appropriate storage location
The place where metal materials are stored, whether inside or outside the warehouse, should be kept away from dry factories and buildings that produce harmful gases and dust. Can not be mixed with acid, alkali, salt, gas powder, etc. When storing different kinds of metal materials in the same place, clear gaps are required to prevent contact corrosion.
Among the metal materials, pig iron, steel, forgings and other large and bulky materials are corroded on the surface, but the quality and specifications are not affected, and they can become disappearances during processing and are stored in the open stock yard. General steel, pipes, etc. can be put on human film or cushions, all small steel, sheet, precision pipe, metal products, non-ferrous gold should be stored in the warehouse.
