绝缘是镀铁的重要一环。要搞好批量生产,必须解决好绝缘问题。因此,寻找一种涂敷容易、取下方便、绝缘可靠、性能稳定、能耐酸、耐碱、耐温、成本低廉的绝缘材料,是一项十分紧迫的任务。我们通过大量的试验,获得了比较满意的绝缘材料,其配方是:白蜡:601环氧树脂:沥青=1:2:10将601环氧树脂和沥青分别加热熔化,去泡后混合,再加入白蜡,搅拌均匀即可使用。浸渍温度在220～240℃之间,浸入时间为1～3秒。一般温度高、时间短,绝缘层就薄。但温度不宜超过270℃。此种绝缘材料对于修整待镀部
Insulation is an important part of iron plating. To do a good job mass production, must solve the insulation problem. Therefore, it is a very urgent task to find an insulating material that is easy to apply, easy to remove, reliable in insulation, stable in performance, and capable of withstanding acid, alkali, heat and low cost. Through a large number of experiments, we obtained relatively satisfactory insulation materials, the formula is: white wax: 601 Epoxy resin: Asphalt = 1: 2: 10 601 Epoxy resin and asphalt were heated and melted, defoamed and mixed, then add White wax, stir well to use. Impregnation temperature between 220 ~ 240 ℃, immersion time of 1 to 3 seconds. General high temperature, time is short, the insulation is thin. But the temperature should not exceed 270 ℃. Such insulating material is to be trimmed to be plated
