When storing metal materials, clean and dry operations both inside and outside the warehouse, away from factories and workshops where harmful gases and dust are generated, and do not store them with acids, alkalis, salts, gases, powders and other substances that are thick and turbid
1 Choose a suitable storage occasion
Register in batches; when different types of metal devices are registered at the same address, there must be obvious intervals to avoid touch corrosion. Usually hot-rolled steel, etc. can be stored in the shed or be added; all magnesium alloys, small steel, thin plates, steel strips, fine devices, metal products and non-ferrous metal materials should be stored in the warehouse, and can be stored in a dedicated warehouse if conditions permit. storehouse.
2 insist that the warehouse is boring
Ensure that the relative humidity of the warehouse is below the critical humidity, usually the relative humidity should be controlled at 70% or so. Manage the temperature and humidity of the warehouse well, keep abreast of climate changes, avoid hurricanes and rainstorms, and use ventilation methods to cool down and lower tides. Placing desiccant in the storehouse can also raise and lower the moisture effect. Insist on the dryness of the warehouse is an important condition to ensure the storage of hardware products to avoid or reduce rust.
3 Proper stacking, thatch pad and sealing
Proper stacking and thatch pads are also one of the links to prevent moisture and damage to hardware products. The palletizing request should be reasonable, firm, quantitative, regular, and save space. The seal blocks the metal material from the outside air, reducing the influence of moisture on rust. The metal material retained by the seal must not be exposed to moisture before the seal, and the quality is flawless.
4 Anti-rust by oil injection
In the humid and hot area of the south, the metal parts stored in the open air cannot achieve the expected rust prevention purpose only by using thatch cover. They can be sprayed together to prevent rust. For oily people, this method cannot be used.
