Metal Processing Online Lecture: Management of Cutting Fluid
When purchasing cutting fluid, the plan should be used. The general reserve should not exceed 3 months . The cutting fluid should be used in the order of purchase. Oil-based cutting fluids can be stored for several years, but water-based cutting fluids can only be stored for 6 to 12 months. Storage and storage of cutting fluid should be indoors and stored at a temperature of 5~40 °C. If stored outdoors, prevent direct sunlight and exposure. In summer, some areas have higher outdoor temperatures, which are harmful to the cutting fluid and tend to cause deterioration. Water-based cutting fluids should pay attention to it.
In addition, it is necessary to prevent rainwater from entering. When rainwater is mixed into the oil-based cutting fluid, the lubricity and rust resistance are lowered. When the rainwater is mixed into the water-based cutting fluid, the additive may be separated or gelled. Oil-based cutting fluids typically have a pour point of no more than -5 ° C, while water-based cutting fluids typically provide safety at -5 ° C. Generally speaking, there will be no freezing problems in the southern region, but in the northern regions, attention should be paid to antifreeze. In particular, when the stock solution of the emulsified cutting fluid is frozen, the temperature is raised to cause separation after being melted, and most of them cannot be used. If the cutting fluid freezes, stir it well after thawing, or roll the container on the ground, mix it evenly, and then take a sample to check if it can continue to be used.
The container containing the cutting fluid should be clean and sealed. Iron drums with galvanized inner surfaces cannot be used because the galvanized layer may react with the components of the cutting fluid to form zinc soap. When storing outdoors in an upright position, the direction of the opening should be upwards, and a seal must be applied to it. Keep the opening part above when laying it horizontally to avoid being immersed in rain.
Oil-based cutting fluids are flammable, and a certain amount of processing and storage is subject to fire protection laws and legal restrictions on dangerous goods. According to GB50156-92 "Design Code for Small Oil Depots and Auto Gas Stations" and its stripe description, inflammables and combustibles are classified into Class A, B and C according to their closed cup flash points, of which Class C is closed cup flash point. Oils above 60 ° C. In general, the cutting cup of cutting oil and emulsified oil is much higher than 60 ° C, so it belongs to Class C flammable liquid. Although fire safety is high, it must be strictly managed. For the emulsified cutting oil containing mineral oil as the main component, it should also be treated according to the oil-based cutting fluid.
