Drawing a bath oil
Time：2016-09-23 19:54:43Reading：6125 one. Prepare in advance:
1. a bath with the water quality testing: its purpose is to determine whether a bath is a good emulsion stability and drawing oil for future tracking of test items:
hardness.
PH.
Electrical conductivity.
The number of bacteria.
2. sump cleaning
Freshly dug sump before use must be thoroughly cement wall a large amount of insoluble material and the bottom of the pipe and wash it off in order to avoid a bath or dirty remnants (plastic bags. Rags. Wires, etc.) , resulting in unnecessary waste of drawing oil extraction pumps and pipes or clogging.
The old oil tank has been used before to replace the add 0.1-0.15% of fungicide in the old drawing solution, maintaining membership in order to continue to produce clear the pipeline, tank wall and the machines that may accumulate microbes. Add 24 hours before the timing for the replacement. After the old fluid extraction, make sure the tubing. Clean inner wall and the sump machines.
Second, a bath:
1. When a bath, since drawing oil interfacial activity of the most active and less anti-foaming ability, so a bath level best to soak only 70-75% of a predetermined amount, to reserve space bubble, the liquid to be brushed the copper ions (ie, color drawing liquid with apple green or blue, it means that there are suds role), the liquid and then gradually increase the amount to 80% of total oil sump capacity.
2. a bath, first the required amount of water injected into the oil sump and circulated. Since the time of drawing oil added to water, has its dissolution rate, thus adding, absolutely avoid all the required amount of water was added, must be at least twice more plus points, the number the better, the addition amount of the first completely dissolved, then only amount of a second, and make it completely dissolved before starting work. But also must add side side loop, summarized as follows in order to obtain the most stable emulsified state drawing oil. (The amount of water is added to 1/2, while adding water, while adding new oil in the pipeline, the full cycle of the machine.)
3. After the addition is complete the oil, drawing oil in the pipeline so that the machine fully recycled to 4-8 hours, until new oil fully dissolved, bootable job. Since the beginning with the new oil, the oil temperature is low, with oil concentration should be lower than normal, slow boot time to speed until the oil temperature rose above 35 ℃, the machine speed can be slowly increased to normal, and then drawing oil concentration raised to the normal range.
4. Copper good drawing a bath in the spinning solution has not been reached in the resulting copper ions sufficient to produce the former, the drawing must be liquid fatty acid alkali (i.e., calcium magnesium ion content) and the chemical reaction of the hardness of water to produce insoluble hard water soap in water, the higher the hardness, the more rigid alkali produced. When this base hard water will float on the liquid surface, to be absorbed sufficient quantities of oil and copper, it will settle to the bottom. Preferably, however, at the time not yet had settled, it will be picked up, in order to avoid excessive absorption of oil and reduces the concentration of drawing fluid, in addition to increasing the consumption of drawing oil, but also will affect the lubricating emulsion stability, drawing liquid shortening life.
5. If the fuel tank when a filter device, the circulating fluid in a bath of Time (Not before dissolution). Can not make drawing liquid through the filtration equipment to avoid undissolved drawing oil is filtered, unnecessary waste.
6. After the drawing was completely dissolved, the former is not in use, the sample to detect the following, that the future management Track:
concentration.
PH.
Electrical conductivity.
The number of bacteria.
7. Our drawing is based on the size of the diameter of the oil to divide, WT-2053 fine drawing oil for drawing wire 0.08mm or less, concentration 2-4%; WT-2050 fine drawing oil for wire stretched between 0.08-0.5mm, a concentration of 2-4%; in drawing oil for between 0.5-8mm wire pull Clifford Chance, the center line of 0.5-2.6mm, a concentration of 4-6%; large line 2.6-8mm, a concentration of 8-12%.
In order to increase the service life of drawing oil, drawing oil can be recycled. Such as micro salad oil (WT-2053) to use a cycle, can be placed in Selah oil use, Selah oil (WT-2050) to use a certain period can be placed in the big pull oil pool use; in pull oil (WT-2052) can be put to use in the continuous casting and rolling. Since the difference in performance of the oil in the new oil, the oil can not be a small pull pull oil and mix, so as to avoid excessive foaming, affecting the heat wire.
