一、在化工机械设备维修中推广应用热喷涂技术的意义在化工机械设备维修中,大量的机器设备和化工容器是处在具有腐蚀环境条件下或在腐蚀介质气氛中工作的,它们因受到严重的腐蚀和磨损等方面的影响而不得不停产大修,特别对一些传动机器零部件的磨损,泵叶轮的气蚀,管道、弯头和阀门阀口等管件受到冲刷和热蚀等作用而严重威胁着化工厂的安全生产。尽管油漆技术、电镀技术和热
First, the significance of the promotion and application of thermal spraying technology in the maintenance of chemical machinery and equipment In the maintenance of chemical machinery and equipment, a large number of machinery and equipment and chemical containers are in a corrosive environment or working in an atmosphere of corrosive media, they are severely affected Corrosion and wear and have to stop production and overhaul, especially for some transmission parts wear and tear, pump impeller cavitation, pipes, elbows and valve port and other pipe fittings are subject to erosion and thermal corrosion and other serious threat Chemical plant safety. Despite paint technology, electroplating technology and heat
