Product Description

Jiangsu high-tech products “RTV anti-pollution flash paint”
In December 2016, the jiangsu province department of strict review, the company products “RTV pollution flashover dope”, earned a high-tech products in jiangsu province, and issued the certificate of high-tech products in jiangsu province.
The acquisition of this high-tech product certificate further enhances the core competitiveness of the company, which is conducive to the company’s brand advantage.Company will also take this opportunity to constantly increase investment in technology research and development, is committed to its own development and application of high and new technology, product, give full play to the advantages of independent intellectual property rights for the company to lay a solid foundation.

“Flash” is a long-standing problem of power transmission and distribution system security problems, serious harm to the power system operation is stable and reliable in the column climate (such as fog, dew, rain, etc.) along the vast ion surface wet flashover, pollution flashover accident caused by power system. It affects the local power supply, or impact on the power grid, even the whole grid caused cracking, causing huge losses to the national economy. The power system of outdoor equipment electric porcelain surface natural contamination phenomenon is inevitable, with the development of the national economy, air pollution is more serious, the pollution source is increasing, the salt density increased year by year. The voltage allowed and transform uneasy the climate and other factors, the possibility of flashover growing. Our company since the last century, 90s on the anti pollution flashover coating technology research and launched a single RTV long-term RTV coating. Through these years. Use, coated with anti pollution coating line little pollution flashover. With the rapid increase of national grid load, the construction of EHV transmission line is increasing, with the support of the insulation has been unable to meet the needs of the situation of anti flashover performance of the product surface, must use high performance coatings to solve Kang flashover flashover the problem. At the beginning of this century, our company has successfully developed the PRTV ultra long RTV coating, the quality of the products the leading domestic, has been applied in more than a dozen provinces and cities, for the security and stability of power system and make a contribution.

 

Characters:
Low viscosity, easy to spray, strong operability
Good migration performance of hydrophobicity, resistance to water and damp
Excellent electrical insulating performance and aging resistance performance

 

RTV operation process:
1. Use dry cloth to clean the surface of insulator before using, then it can be operated in good weather.
2. Spray on clean and dry surface when operating, the coating thickness should be over 0.25mm, holidays should be avoided.
3. The tack free time would be about 30 minutes, and the completely cured time would be 24 hours after operation.

Notes:
1. Seal packing barrel as soon as possible after opening or using, avoid coating exposed to air for a long time, in order to prevent the coating cured.
2. Operate in good weather, avoid operating in rain, fog or sandstorm weather to ensure the operation quality.
3. Porcelain insulator should be cleaned before painting, strictly prevent oil stain, dirt or moisture on the surface of porcelain insulator.
4. When repainting the painted insulators, remove the dirt on the surface, peeled and warped coating first. But it is not necessary to remove the original coating which has good adhesion but without efficacy, just repaint on it, it would not affect the repaint quality.

 

Daily maintenance:
1. In the normal inspection work, if the mechanical external forces are found in the coating, the damage should be covered or repainted.See note 4 for mending or repainting.
2. The fog, dew coating hydrophobic weather observation, if the coating hydrophobic Angle is less than 90 °, disappear or hydrophobic Angle, 48 hours not recover for failure, namely should arrange touch-up or applied.The method is the same.

 

Packing:
1. 5 KG/iron drum; 10 KG/iron drum
2. Also can be customized

 

Storage and transportation:
1. Avoid light, heat and keep ventilated and dry
2. Shelf life is 12 months (25℃)
