High self-cleaning antifouling flashover coating (PRTV-Ⅳ) is a kind of polymer complex composed of organosilicon and organic fluorine which can be curable at room temperature. The product retains the original characteristics of antifouling flashover coating and introduces the organic fluorine monomer, which makes the advantages and disadvantages between the two materials. It is a high self-cleaning antifouling flashover coating with excellent self-cleaning properties and good hydrophobicity, oil phobic and weather resistance. The exceptional water resistance of this product makes up for the common loss of hydrophobicity of common antifouling flashover coatings and composite insulators in continuous humid climates, and can effectively reduce the occurrence of unknown flashover of common antifouling flashover coatings and composite insulators.
a. High self-cleaning: no maintenance, no cleaning, self-cleaning, fluorocarbon coating has deficient surface energy, surface dust can be self-cleaning through rainwater, excellent hydrophobicity (water absorption rate is less than 5%) and oil repellent, minimal friction coefficient (0.15 ~ 0.17), non-stick dust scaling.
b. Good antifouling. Ultra-long weather resistance: the coating contains a large number of F-C bonds, which determines its strong stability, no powder, no fading, and service life of more than 20 years, with more excellent performance than other similar coatings.
c. Excellent detest water transfer: detest water transfer level up to 5, much better than ordinary antifouling flash paint.
d. Extremely long hydrophobic loss time: The loss time of hydrophobicity and hydrophobic migration is 10 times longer than that of ordinary antifouling flashover coating PRTV (the coating of ordinary antifouling flashover coating can run continuously for 1 ~ 2 days in dense weather and drizzle weather, and the coating of high self-cleaning antifouling flashover coating can run safely continuously for more than 20 days in dense weather and drizzle weather). Ensure the safe and reliable operation of the equipment in continuous rainy and humid climates.
e. Good self-cleaning performance of the coating, corrosion resistance to acid, alkali, salt and strong oxidant, free of maintenance and cleaning under normal conditions within the effective period; It can replace the periodic cleaning and washing of the external insulation of the equipment, greatly reducing the human and financial costs of the periodic maintenance of the equipment.
f. The coating has high anti-fouling flashover strength and strong adhesion, which does not affect the equipment maintenance personnel's stepping on the surface of the coating.
g. High-cost performance, the comprehensive cost is much lower than replacing electrical equipment, and the total performance is better.
This product is mainly used for the antifouling flash treatment of external insulation of power transmission and transformation equipment; It is especially suitable for external insulation protection of electrical equipment in coastal areas, heavy oily dirt areas, easy pollution, easy fog, and wet. It is suitable for external insulation protection of AC-DC system equipment with rated voltage from 1 to 1000 kV, ambient temperature from -50℃ to 250℃, operating under dirty conditions, to prevent flashover and improve the insulation level of equipment. In addition, this product is applied to the outer insulation of high-voltage switchgear, box transformer and common box bus insulation components, which can effectively prevent the discharge and flashover phenomenon caused by humidity.
