What should be noted when applying water-based insulating paint resin?
Water-based Insulating Coating Resin acts as a UV stabilizer; the reinforcing agent, used as a pigment, enhances the material's mechanical properties, increases its opacity, reduces costs, and even modifies the material's electrical and thermal conductivity. Before curing, it exists as a liquid with excellent flowability—though the viscosity of the adhesive can vary significantly depending on the product’s material, performance characteristics, and manufacturing process.
Common epoxy resins soften or even char under intense heat above 100°C, whereas water-based insulating paint resins remain stable even at scorching temperatures of 120°C. On the contrary, their performance actually improves over time and with rising temperatures—showing enhanced hardness and adhesion. During production, the particle size of pigment carbon black is carefully controlled between 800 and 1000 mesh. If the particles are too fine, carbon black’s moisture-absorbing properties increase, making storage more challenging. In cases where humidity levels are excessively high, drying equipment should be employed. Additionally, cotton fiber tubes, known for their poor heat resistance, moisture protection, and mold resistance, are gradually being replaced by fiber and synthetic fiber tubes in various applications.
So far, water-based insulating paints applied to resin pipes have mostly used low-grade glass fibers, with the primary coatings including oil-based insulating paints, alkyd coatings, acrylate coatings, silicone coatings, silicone rubber, and modified polyvinyl chloride.
Water-based insulating paint resin is used in electrical equipment to coat energized components with differing potentials. Therefore, the insulation material must exhibit high insulation resistance and dielectric strength to prevent accidents such as leakage current or breakdown. Additionally, it should possess excellent heat resistance to avoid aging caused by prolonged overheating. Furthermore, the material should also offer good thermal conductivity, moisture resistance, and lightning protection, while maintaining high mechanical strength and ease of processing.
What are the convenient aspects to keep in mind when applying water-based insulating paint resin?
1. Applying Graphite Coating: Regardless of the coating applied to the graphite, always start by brushing a metal transition layer; for particularly poor-quality graphite surfaces, apply a fiber-based transition layer instead.
2. Small water-based insulating paint resin components require thermal insulation: These small objects have high surface tension, torsional strength, and tensile strength, making them prone to peeling or cracking after being coated with thermal insulation paint or other lubricants. When applying the paint, it’s best to incorporate mesh materials—such as glass mesh, ceramic mesh, or fabric mesh—into the paint formulation.
3. After removing rust with a brush, use high-purity alcohol to degrease the surface.
4. The paint must be applied to the goose itself, as well as to its source.
5. Available are potassium ions, hydrogen ions, ethyl acetate, hydrofluoric acid, concentrated sulfuric acid, concentrated hydrochloric acid, nitric acid, aqua regia, and more. Depending on the specific conditions, different anti-corrosion coatings must be used—some of which cannot withstand the corrosive media or extreme heat mentioned above.
6. The 800-degree hot-dip anticorrosion coating, coated with water-based insulating paint resin, can achieve even greater hardness as the application time is extended.
7. After sintering at 800°C, the coating becomes dense; however, if the coating is not sintered at temperatures above 800°C, it will not be waterproof.
8. The curing time for the inorganic coating should be 2 hours; however, if the curing environment fails to meet the required conditions, the inorganic coating will begin to crumble after just 2 hours.
