近年来的技术发展使搪瓷成本及能源消耗都大大降低。其中最惊人的技术改进是采用搪瓷“粉末涂层”。它是将搪瓷玻璃料用有机膜(如聚乙烯膜)包起来,进行静电喷涂,再将有机膜烧掉得到搪瓷涂层,从而大大提高涂层质量,降低成本。目前采用的一种由玻璃纤维型耐火材料制成的烘烤炉由于可夜晚停炉而达到节能目的,克服了旧式炉不能间断停炉而耗能的缺点。在预处理工艺方面,采用新型湿状粉末搪瓷玻璃料,可取消酸洗等过程。此外对消除涂层表面黑
In recent years, the technological development has greatly reduced the cost of enamel and energy consumption. One of the most amazing technological improvements is the enamel “powder coating.” It is the enamel frit with organic film (such as polyethylene film) wrapped up, electrostatic spraying, and then burn the organic film enamel coating, thereby greatly improving the coating quality and reduce costs. Currently, a baking oven made of fiberglass-type refractory material achieves the purpose of energy saving by stopping the oven at night, and overcomes the defect that the old-type oven can not shut down and consume energy continuously. In the pretreatment process, the use of new wet powder enamel frit can be removed pickling and other processes. In addition to eliminate the coating surface black
