Industrial paint solution: equipment, steel structure and chemical engineering landscape

I. Preamble

Industrial corrosive problems seriously affect the useful life of equipment and the safety of production. It's winter.Anti-corrosion coatingsBy virtue of its superior chemical corrosive properties and rapid curing, it has become the preferred material in the industrial field. This paper will provide a professional CORPORATION protection solution for equipment, steel structures and chemical sites.

II. Types of corrosion and protection mechanisms

Common corrosion type for 2.1

• Chemical corrosive: chemical medium erosion such as acid, alkalis, salt, etc.
• Electro-chemical corrosive: exposure of metals to electrolyte solutions produces electrochemical reactions
• Physical corrosion: mechanical effects such as wear, brush, shock
• Biocorrosion: Corrosion from microbial metabolites

2.2 polyaspartic protective equipment

• Blocking: Cyclical coating to prevent corrosion media infiltration
• Gravity: The slowness agent in the coating inhibits corrosive reaction
• cathode protection: electrochemical protection in conjunction with zinc-rich paint
• Self-rehabilitation: flexible coating adapts to the deformation of the base material and prevents cracking
