在生产铜单丝的过程中，我们往往会忘记对皂液的维护与保养，在实际生产过程中，将皂液维护好是高效高质生产的一个大前提。

In the process of producing copper monofilament, we tend to forget the maintenance and maintenance of the soap, in the actual production process, the maintenance of soap is a major prerequisite for efficient and high quality production.

皂液起到三个作用。清洗，铜杆在拉伸过程中，不断产生细微的铜粉，皂液不断冲洗模孔，避免模孔堵塞；冷却，铜杆变形时产生热量，皂液将热量迅速传导出去，降低铜线与模孔的温度，防止线材因温度过高产生氧化变色现象；润滑，在铜线与模孔间保持一层润滑模，避免模具与金属直接接触粘连，降低摩擦系数减少摩擦，使金属沿受力方向均匀变形，并可增加铜材的变形程度，减少能量消耗和加工道数，延长模具使用寿命。由此可以看出，皂液的质量将直接影响拉线的质量。EV-WDYJYJ充电桩电缆

Soap has three functions. The cleaning, the copper rod in the stretching process, continue to produce fine powder, liquid soap to flush the die hole, the die hole to avoid clogging; cooling, heat generation of copper rod deformation, heat conduction liquid soap will quickly go out, reduce copper wire and die hole temperature, prevent wire oxidation discoloration due to high temperature lubrication; keep a layer of lubrication mode in copper wire and die hole, to avoid the direct contact between the metal mold and adhesion, low friction coefficient and reduce friction, so that the metal along the stress direction of uniform deformation, deformation degree and increase the copper, reduce energy consumption and processing times, prolong the service life of the die. It can be seen that the quality of the liquid soap will directly affect the quality of the cable.

皂液对拉线的影响有三个方面：

There are three aspects of the influence of soap on the cable:

（一）浓度，润滑效果与浓度有密切关系。皂液度增大，铜材与模壁的摩擦系数减小，相应的摩擦力也减小，拉伸力也随之下降。反之，摩擦力增大，所需拉伸力也上升。然浓度过大，皂液的粘度也随之上升，冲洗模孔的作用将减小，且拉伸中产生的铜粉不易被皂液冲洗带走，造成线材表面起槽等质量问题；浓度过小，铜粉易悬浮在皂液中，不易沉淀，将影响润滑效果及拉伸后单丝表面质量。因此，浓度的控制很重要，相对于铜大拉而言，浓度在5%~8%之间是一个比较理想的状态。EV-WDYJYJ充电桩电缆

(a) concentration, lubrication effect and concentration are closely related. With the increase of the degree of soap, the friction coefficient between the copper and the die wall decreases, the friction force decreases, and the tensile force decreases. On the other hand, the friction increases, the tensile strength is increased. However, the concentration is too large, the soap liquid viscosity also increased, the effect of die hole flushing will be reduced, and the tension generated in the copper powder is not easy to be washed away by the liquid soap, the surface of the wire groove and other quality problems; the concentration is too small, easily suspended in liquid soap powder, not easy to deposit, will affect the surface quality the lubricating effect and tensile tensile. Therefore, the concentration of the control is very important, relative to the copper, the concentration of 5%~8% is an ideal state.EV-WDYJYJ充电桩电缆

（二）温度，当皂液的温度过高，线材拉伸时产生的热量不易带走，使铜材与模具的温度升高，并使单丝氧化变色，降低模具使用寿命，也会影响幼稚润滑膜的强度，润滑效果下降。皂液温度过高，还易产生油水分离现象，对设备及模具的寿命都会造成影响。铜大拉皂液温度应控制在25~55℃。

(two) temperature, when the temperature is too high to produce soap, wire stretching when the heat is not easy to take, copper and mould temperature, and the discoloration of monofilament, reduce mold life, will also affect the naive lubricant film strength, lubricating effect decreased. Soap liquid temperature is too high, but also easy to produce oil and water separation phenomenon, the equipment and die life will have an impact. The temperature should be controlled at 25~55 C.

（三）清洁度，简单的说即是它的酸碱度，当呈酸性时，皂液内部容易滋生厌氧菌，造成液体发黑发臭，腐蚀铜材与设备；当呈强碱性时，残留在铜线表面的皂液也会对其造成腐蚀，因而皂液的PH值在7~7.5左右*为适宜。

(three) clean, simple to say that it is the pH, when acidic soap is easy to breed, internal anaerobic bacteria, causing fluid stinks and corrosion of copper and equipment; when the alkaline residue in the liquid soap, the copper surface will cause the corrosion, and soap pH value about 7~7.5 in the most suitable.

影响皂液的外界因素有两点：

There are two factors influencing the soap solution:

（一）循环量，皂液池内液体循环至设备内部的循环量要大，若循环量小，机体内温度高，流速慢，则散热效果不明显，出现上述（二）内描述的情况。循环量大，不仅冷却效果好，也影响其清洗效果，皂液一直在循环，内部充盈氧气，不易滋生厌氧菌。

(a) circulation, circulation of the liquid soap in the pool to the internal liquid circulation device to a large, if the small amount of circulation, the temperature is high, the body is slow velocity, the cooling effect is not obvious, the (two) in the description of the situation. The circulation quantity is big, not only the cooling effect is good, also affects its cleaning effect, soap liquid has been in circulation, the internal filling oxygen, not easy to breed anaerobic bacteria.

（二）皂液间通风效果，皂液间空气流通则不会形成密封的环境，则厌氧菌没有合适的生存空间，使得皂液的寿命得到保障；另外，通风效果良好，对皂液的温度也有轻微影响，皂液池散热快，避免出现油温过高的现象。

(two) the effect of ventilation liquid soap, soap liquid between the air circulation will not form a sealed environment, while anaerobic bacteria no suitable living space, making soap life security; in addition, good ventilation effect, the soap temperature slightly, soap liquid pool heat quickly, avoid the phenomenon of oil temperature high.

我们在考虑拉丝工序时，不仅要考虑配模、设备等因素，皂液亦是一个不可忽视的环节，只有各个环节相互衔接，我们的产品才能保质保量，达到一个新的高度。

We consider the wire drawing process, not only to consider the distribution mode, equipment and other factors, the liquid soap is also a link can not be ignored, only each link with each other, we can guarantee
