Ningbo Qiaopu Electric Co., Ltd. production of emulsion preparation of the power cord

Qiaopu production process of the power lines need to use the power cord emulsified oil to cool down the temperature of PVC, thus ensuring that the power cord will not be brittle or deformed, Qiaopu production power cord emulsion is how prepared it?
(1) replacement when the emulsion, suitable for 20 ~ 35 ℃ warm water emulsion preparation, the emulsion more stable, especially in winter, such as the preparation used in cold water will cause the oil or emulsion layer analysis, affect the results.
(2) should be brushed with the liquid slowly into the oil sump with water and continue to stir or turn the pump cycle to achieve the requirements of the concentration.
(3) of copper wire drawing emulsion tour is a balance system, it can not be mixed with other manufacturers' products, product performance will be affected and normal use.
(4) the replacement of the emulsion should be preceded by the emulsion tank, pipes and wire drawing machine pulley mold clean.
(5) should be first brought down drums, rolling several times, so full of oil even in winter should be used prior to use copper wire drawing oil, restitution, or the heating temperature to 50 ℃, to ensure adequate liquidity to facilitate the inverted bucket and with liquid, to ensure the stability of emulsion preparation.
(6) used in the preparation of emulsions of water is very important, often with hard water emulsion prepared quickly layered, precipitated a large number of oil and water-insoluble soap, affect the results on the other hand, if water is too soft, foam may be increased such as water is too hard to be too pre-processing, can be added to the water of 0.1% to 0.3% of sodium tripolyphosphate or sodium EDTA can reduce water hardness from the role, but adding too much can cause sodium tripolyphosphate bacteria, fungi reproduction, so it is best to use soft water in general, such as tap water or deionized water quality should be colorless, odorless, non-mechanical impurities and suspended solids, PH value of 6.5 to 8.5, chloride ion content in water should not exceed 100mg / L. or will cause corrosion.
