How to distinguish the quality, construction, and storage of epoxy resin-coated steel pipes

how to distinguish the quality of epoxy resin coated steel pipe:
the real epoxy resin-coated steel pipe is the anti-corrosion macrostructure of the pipe. it uses electrostatic adsorption to electrostatically adsorb the modified epoxy resin powder on the inner and outer walls of the steel pipe. usually, companies that can say the same name are deceiving customers. , the product performance of the plastic-coated composite steel pipe has been recognized by the majority of customers, and the customer can distinguish it in real-time to prevent being cheated after cooperation, smoothness, and other characteristics. the so-called cold-sprayed plastic composite steel pipes appeared on the market, and recently we found a serious problem when we were doing customer return visits, that is, spraying odorless paint based on ordinary steel pipes to make the surface firm, and then using them under high temperature the powder is called epoxy resin that physically reacts and adheres to the inner and outer walls of the steel pipe to prevent it from being cheated.

construction and storage of epoxy resin anti-corrosion steel pipe
(1) before painting, the dust, oil, scale, etc. on the surface of the object must be cleaned. reach sa 2.5 level to ensure the quality of the painting. it is strictly forbidden to bring in water during construction.
(2) the construction ratio method is: open the mouth of component a, add component b into component a, and stir well. after curing for 30 minutes, it can be painted.
(3) this material is required to be used as it is prepared, and the proportioned paint must be used up within eight hours. unfinished materials should be kept sealed. construction should be stopped on rainy days or when the relative temperature is greater than 75%. for parts with severe corrosive media, multiple coats are recommended.
(4) the product should be stored in a cool and dry place, prevent direct sunlight, isolate fire sources, and keep away from heat sources. the storage period is twelve months. after the expiration, all technical indicators should be inspected. if the indicators meet the requirements, they can continue to be used.
