Places for the storage of the metal material, no matter the rolls outside the storehouse should be clean and dry, which should be away from the harmful gas and dust in the workshop.And it can not be stored with acid, alkali, salt and mixed gas, powder materials, partial deposit is the best to store them. When different kinds of metal equipment are recommended to be placed in the same place, it is necessary to have a clear separation distance to prevent contact corrosion. Magnesium alloy, small steel, thin plate, steel belt, precision equipment, metal products and non-ferrous materials should be stored in the warehouse, and it can also be stored in a dedicated warehouse if with conditions.
1.Keep the warehouse dry.Ensure that the relative humidity of the warehouse is below the critical humidity, and the relative humidity should generally be controlled at about 70%. Manage the temperature and humidity of the warehouse, keep abreast of weather changes, avoid typhoons and rainstorms, and use ventilation to cool down and reduce moisture. The drying agent can also take off the moisture. Keeping the warehouse dry is an important condition for preventing or mitigating the corrosion.
2.Good palletizer and sealing
The appropriated palletizer is also one of the links of the hardware products. The stacking requirements are reasonable, firm, quantitative, orderly and economical. The sealing causes the metal material to be isolated from the outside air and reduces the influence of moisture on the corrosion.
3. Prevent being rusty by oil injection
In the southern humid areas, if the metal equipment is stored in open air, using the palleitzer can not achieve the expected purpose of preventing being rusty,but it can be oil sprayed on the surface at the same time.But as for the building reinforcement ,such as the steel in cold drawn and other unfavorable injection,this method can not be used.
4. Protective layer and packaging of protective door hardware accessories
In order to prevent metal products from rusting, it is generally used for anti-rust treatment, such as chemical treatment to produce protective film, coating anti-rust agent or anti-rust packing. In handling, loading and unloading and storage, it is necessary to prevent damage to the outer layer and packaging, and do not cause damage, damage or compression deformation. The packers should be repaired or replaced, and the dampers should be treated with dry treatment, and the oil should be removed if the oil is dirty or dry.
