TH-847 energy-saving anti-corrosion coating water cooler(ZHONGHAI system)

    Using scope of coating    

1.Carbon steel heat exchanger, steel water coolers, reboiler tubes, air or other nonstereotyped heat transfer equipment. 
2.Designed to operate within a temperature range of 150℃ , long-term working temperature of about 100℃ 

    Implementation standards             

SH/T3540 《producing and inspection rules for complicated coating of tube of steel heat-exchanger》

    Suitable coating material     

1.Fresh water, ocean water, bitter alkaline water, salt industrial recycling water, distilled water and steam. 
2.Weak-acid medium and alkaline medium, sulphur medium ,can resist steam purging120℃ 
3.Gaslion, fuel oil, solvent oil. Crud oil, engine oil, vacuum pump oil and other oil-water high temperature exchanger.
 
    Technical property of coating    

1. Excellent water resistance, temperature resistance, corrosion medium containing industrial water-resistant, and good dirt resistance and thermal conductivity; strictly thorough surface treatment, suitable for all types of water coolers painting methods, specially designed baking system advanced construction technology integration site construction motorized devices, is a reliable coating quality assurance.
2.The coating performance: The cured coating film at a high temperature. The coating is clean and smooth, flexible hard, good 
thermal conductivity, stable physical and chemical properties.

Not:Good heat conductivity, good dust resistance, measuring 150±30μm, the thermal resistance is 1.85×10-4㎡ .h.℃ .kcal, because the tube can no longer produce rust with high thermal resistance, the heat exchange efficiency improves greatly. 

Detection index of coating quality Detection of apperance: the surface is clean, no foreign matters, no bubbles,no flows, the color and the sense are unanimous. 
Depth of coating: according to the standard SH/T3540, the depth of dry film is 150±30μm 
Side leakage of coating: tested with electrical spark apparatus, re-painting if there is any leakage of coating film. 
Detection of coating film: before installation and use, trying to avoid any mechanical collision or flexible friction in the process of 
transportation and removal repair. Please entrust our company to repair in the field if any coating mechanical damage.
