Need to pay attention to the preparation of drawing lubricant

The preparation process of lubricating fluid is reasonable, has great influence on the service life of lubricating fluid.
In the copper contact wire drawing machine drawing before of wire drawing machine, mold base, lubricant and lubrication pipes after relaxation are pineapple with tap water were thoroughly cleaned, with caustic soda solution or aqueous formaldehyde solution immersion (or Li wash) lubricating liquid pool for sterilization. Discharge of caustic soda solution or aqueous formaldehyde solution, rinse the entire circulatory system to clean.
Preparation of lubricating fluid with water should be soft water (tap water or deionized water), the water should be colorless, odorless, no suspension and mechanical impurities, pH value of 6.5 ~ 8.5. If the local water quality is excellent, want to consider adding processing device for eliminating electric ions in water, but should avoid the use of salt crystal class treated water; if the suspended matter too much or pH value is not within the scope of the requirements, but also to the device for purifying water on a set, and the pH value to make the appropriate adjustment of the rear can make use of chloride ion content in water is too high (> 100rag / L), it should not use, or by adding distilled water to reduce the chloride ion content in solution. Preparation of lubricating fluid before, should first put down, packing barrel lubricant rolling several times. The lubricant after before use. The storage period is too long, deterioration of the lubricant shall prepare the lubricating liquid. The lubricating liquid pool at the same volume should be large cross section is appropriate, this settlement defoaming and copper powder for lubricating liquid. The concentration of lubricating fluid, the concentration of the reference data must be based on the processing of wire specifications and lubricant production factory provides (or according to their own experience) for the preparation. With new lubricant must be before it can be used after fully mixing evenly.
