四氟统包绝缘彩色导线,过去芯线都用镀银铜线,因为四氟绕包绝缘彩色导线,要在高温接近400℃中进行着色绕结,在这样高的温度下不变色,采用镀银铜线是比较好的。但是,镀银铜线要经过电镀、拉丝、退火等工艺才能生产出来,因此镀银铜线的价格就比较贵,所以生产出来的四氟绕包绝缘彩色导线,一般都用在军工产品上。要使四氟统包绝缘彩色导线推广到民用,首先要降低四氟绕包绝缘彩色导线的价格。因此,我们采用铜芯线做四氟绕包绝缘彩色导线,为了铜芯线在高温下不氧化,不变色,设计了四氟着色远红外加热的水封烧结炉,使炉中没有氧气,所以铜芯线四氟绕包绝缘导线,在着色烧结时铜芯线不会氧化,不会变色,经过试验已经成功。生产了裸铜线四氟绕包绝缘彩色导线。
PTFE insulated package color wire, the past are used silver-plated copper wire, PTFE wrapped around the insulated color wire, to close the high temperature in the vicinity of 400 ℃ coloring, no change in color at such a high temperature, the use of plating Silver copper wire is better. However, silver-plated copper to go through electroplating, drawing, annealing and other processes can be produced, so the price of silver-plated copper is more expensive, so produced PTFE wrapped insulated color wire, are generally used in military products. To make PTFE insulated wire insulation extended to civilian use, we must first reduce the price of PTFE wrapped insulated wire. Therefore, we use copper wire to make PTFE wrapped insulated color wire. In order to prevent the copper wire from oxidizing and discoloration at high temperature, we designed a water-sealed sintering furnace with tetrafluorochrome far-infrared heating so that there is no oxygen in the furnace, so Copper wire PTFE wrapped insulated wire, copper wire in the coloring sintering will not be oxidized, will not change color, after the test has been successful. Production of bare copper PTFE wrapped insulated color wire.
