According to the purpose, it can be divided into powder for spraying inside the pipeline, powder for spraying outside the pipeline (single and double layer heavy anti-corrosion powder coating, weather-resistant heavy anti-corrosion powder coating), powder for oil well pipe, and powder for three-layer structure anti-corrosion single layer heavy anti-corrosion powder coating, steel bar heavy anti-corrosion powder coating, functional heavy anti-corrosion powder coating； Amanda series heavy-duty anti-corrosion powder coatings are divided into the following five types according to their main uses, see Table 1. Table 1 Product name classification (according to use) AmandaFBEN type heavy-duty anti-corrosion powder coating (special for internal anti-corrosion) 1. Mainly used for anti-corrosion of the inner wall of various pipelines and anti-corrosion of various pipe fittings AmandaFBE series heavy-duty anti-corrosion powder coating 2. Anti-corrosion of outer walls of long-distance pipelines, various containers and pipe fittings ； According to the curing time, it is divided into fast type, slow type and standard type. Amanda three-PE heavy-duty anti-corrosion powder coating (for three-layer PE anti-corrosion) 3. Coating of long-distance refined oil pipelines and natural gas pipelines ； Coating on the outer wall of municipal gas and natural gas pipelines. AmandaFBE568 type diepoxy powder coating (outer coating) 4. Suitable for external anti-corrosion of various long-distance pipelines and used in conjunction with AmandaFBEN568 type as the outer coating. AmandaFBE566 heavy-duty anti-corrosion and scratch-resistant powder coating for steel bars 5. It is suitable for the anti-corrosion of steel bars and corrugated boards in seaports, bridges, industrial plants and other buildings. 1 Powder performance requirements are shown in Table 2 Table 2 Project technical indicators AmandaFBEN AmandaFBE Amanda three PE AmandaFBE568 AmandaFBE566 Density g/cm3 1.3-1.5 There are slight differences due to different colors. 1.3-1.5 There are slight differences due to different colors. 1.3-1.5 There are slight differences due to different colors. 1.4-1.6 There are slight differences due to different colors. 1.1-1.5 There are slight differences due to different colors.
