Custody of hardware tools

(1) the general principles of storage hardware products 
(A) select suitable storage sites 
    Metal storage place, regardless of bank slip outside the library should be dry cleaning operation, harmful gases and dust from the factory floor, not with acid, alkali, salts and gases, powders and other substances mixed storage, to establish points classification , batch stored; different types of metal equipment stored in the same locations, the need for clear separation distance to prevent contact corrosion. General hot-rolled steel and other goods can be stored in sheds or additions to the sheet pad; all of iron alloy, a small steel plate, steel, precision equipment, metal products and non-ferrous materials should be stored storage room, qualified professionals can be stored in a dedicated library. 
(B) to keep dry and the Treasury 
    Treasury to ensure that the critical humidity, relative humidity below the relative humidity control in general should be about 70%. Manage the storage temperature and humidity, to keep the weather changes, to avoid the typhoon, heavy rain, the use of ventilation means cooling, low tide. Place desiccant can also take off and land bank tidal effect. Warehouse storage to keep dry and to protect the corrosion of metal products to prevent or mitigate an important condition. 
(C) proper stacking, thatch mat and sealed 
    Proper stacking and thatch mats are moisture-proof metal goods, loss prevention one of the links. Palletizing requirements so that a reasonable, solid, quantitative, neat, saving positions. After sealing the gold and the outside air isolation material to reduce moisture on the impact of corrosion. Was sealed metal materials, must be received in a sealed before the end of tide, and the quality is intact. 
(D) injection method rust 
    Hot and humid areas in the south, open storage of metal equipment, just covered with thatch rust has not yet reached the desired objective of re-injection can rust, but the building to be reinforced and re-rolled, cold drawn steel, etc. should not be sprayed Oil persons, not this method can be used. 
(E) protective layer of protection equipment and packaging 
    To prevent rusting of metal products, factory-made anti-rust treatment generally, if chemical treatment generated a protective film, Xu cover rust or corrosion packaging. In the handling, loading and storage operations are required to prevent damage to the rust in the outer and packaging, is not so damaged by injury, compressive deformation. Packaging damage should be repaired or replaced, should be taken to drying moisture, rust and oil stains should be removed or re-coated with dried oil. 
(F) maintain the warehouse and equipment cleaning 
    Treasury and the repository of the metal equipment should be kept clean, especially after shipping equipment, such as contaminated water, dirt, the general storage should not be stored, but should be cleared up, quickly put into production use. Metal equipment, hand stained with sweat will rust corrosion, so it must try to avoid contamination of hands sweat hardware. Storage equipment shall not touch the dirt groceries should not be deposited dust. 
(G) strengthen the inspection system, identify problems in time 
    Hardware goods in custody during the inspection system to perform, routine, regular check-phase irregular in order to detect problems in time. Hardware products can only play a variety of rust corrosion inhibition, so there should be a period of custody, should carry out FIFO, the principle of rotation of delivery. 
     Welding very sensitive to humidity, moisture-proof paper or plastic packet applications, stacked on shelves, from the moon to the surface modification agent. 
     Tools ------ measurement tools, in particular, vernier caliper, micrometer and other more sophisticated measuring tools, should the rust will affect the use and accuracy, should be coated with good anti-rust oil and moisture-proof paper or plastic bags, boxes, wrap It should also be careful not to pressure and collision, the two measuring surface should maintain a certain gap. Precision measuring tools in the warehouse storage temperature should be maintained at 18-25. C room. Others such as leather tape measure, wooden spirit level, are also not stored in damp or high temperature, otherwise damage will be bad. 
    Cutting tools such as improper care, cutting edge rust, it will affect the use, it should be coated with good anti-rust oil and moisture-proof paper or plastic bags with a packet, in particular, should pay attention to protection of some edge. Metal cutting tools, high hardness, of the more brittle, not stacked, collisions and falls. 
    Rasp tooth tip to rejection and the rust will affect the surface quality of machined parts, severe rust on the loss of use value, pay attention to custody. File can not be directly applied to the adhesive pattern on the anti-rust oil, otherwise the file cutting teeth when the file within the file cut lost iron blockage, and they can only be coated with a layer of volatile rust inhibitor, so that a layer of protective film formed on the surface.
