目前,我们采用了一种新的工艺措施——非金属防渗涂层,妥善解决了氮化罐的老化现象。如我厂原u—105氮化罐已严重老化而报废,经涂刷非金属防渗涂层后,又投入正常生产。经近半年的实际使用,涂层保持完整,无脱落现象,氨分解率保持在正常工艺范围内,情况十分良好。这种非金属防渗涂层不仅具有使老化氮化罐重新复活的功效,同时还兼有如下特点: 1.非金属防渗涂层配方简单,水玻璃加适量石墨粉调成糊状即可使用。2.涂刷施工方便易行。只要把罐内表面
At present, we have adopted a new process measures - non-metallic impermeable coating, properly solve the aging of nitriding tank. As I plant the original u-105 nitrogenization tank has been seriously deteriorated and scrapped, after brushing non-metallic impermeable coating, and put into normal production. After nearly six months of actual use, the coating remains intact, no shedding phenomenon, ammonia decomposition rate remained within the normal process range, the situation is very good. This non-metallic anti-seepage coating not only has the effectiveness of aging nitrification tank resurrection, but also has the following characteristics: 1. Non-metallic anti-seepage coating formula is simple, water glass plus appropriate amount of graphite powder can be transferred into a paste use. 2 brushing construction is easy. Just put the inner surface of the can
