There are many serious corrosion on equipment in the chemical industry, which work at a temperature between 120-250℃, such as reactors, alumin m oxide evaporator, etc. After a period of use, they often should be repaired locally. If spraying metal powder on them, corrosion resistance is not necessarily good, and the cost is still high relatively; If using common organic coatings such as epoxy coating, heat resistance is usually poor. But by using a fluorine resin coating(e.g. PFA), It is possible to meet the above requirements. However, the current researches on fluorine resin coating spraying process are mainly focused on the Indoor spraying and heated in oven, no one has studied the spot spraying Technology in in-service large pressure vessel, and there is no relevant process parameter on spot spraying and sintering.
