Classification of anti static coating:
The classification of static conductive anticorrosive coatings for storage tanks is mainly divided into film-forming substances and conductive media:
1. Classified by conductive medium, it can be divided into:
鈥擨ntrinsic type: even the film-forming substance itself can conduct electricity, such as conductive polyaniline. However, because the resin is difficult to dissolve and disperse, and the price is high, it has not yet been commercialized.
鈥擜dditional type: it is to add conductive medium to the paint components to reduce the resistivity of the coating film. These conductive media include:
鈶?Liquid electrostatic agent: This type of conductive medium usually floats on the surface after film formation, absorbs moisture to form a layer of water film, thereby reducing the surface resistivity of the coating film. The surface resistivity of the electrostatic conductive paint made is unstable and easy to decay, therefore, it is not suitable for electrostatic conductive anti-corrosion paint for storage tanks.
鈶?Metal powder. Such as zinc powder and aluminum powder. The new zinc silicate primer coating is a kind of antistatic anti-corrosion coating with low surface resistivity, which can also be used in some pure oil cans. However, zinc powder is easy to oxidize and consume, and is only suitable for media with a PH value of 5-9.
鈶?Carbon-based materials: mainly guide electric carbon black and graphite powder. However, the industry believes that the use of carbon-based electrostatic conductive paint is easy to pollute oil products and has poor corrosion resistance. Because the potential difference between carbon and steel is large, the steel is used as the anode in the electrochemical corrosion cell after the coating is partially damaged, and the coating is used as the cathode to form a small anode and a large cathode. GB50393 currently restricts its use. It is estimated that graphene can also be made into anti-static anti-corrosive paint and commercialized in the future.
鈶?Rare earth metal oxide composite mica conductive powder. This is currently used more.
2. Classified by film-forming substances, it can be divided into:
鈥擡poxy: It uses bisphenol A epoxy resin and amine curing agent as the film-forming substance.
鈥擯henolic epoxy: also known as epoxy novolac, which uses the multifunctional group Novolac epoxy resin and amine curing agent as the film-forming substance, due to the high cross-linking degree of the coating film, solvent resistance and heat-resistant medium Better.Special Coating suppliers
