pecial Anti-corrosion and coating  TH-901 oil, heat and corrosion resistant coating (ZHONGHAI system

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

   Using scope of coating    

1.Carbon-steel heat-exchanger, carbon-steel water cooler,re-boiler tube, air cooler and other non-stereotyped heat exchanger. 
2.Corrosion and dust resistance for cooler exchanger of petrochemical, chemical fertilizer, metallurgy, ocean project, power generation and medicine. 
3.Designed working temperature is 300℃ , long-term working temperature is below 240℃ 
   Technical property of coating     
1.Coating ingredients: TH-901 corrosion-resistant coating is formed of resin material from Chinese lacquer which is chemically transformed, and is an one-component coating with many colours , which can be solidified by heated or normal-temperature. This coating has resistance for heat, oil, acid, water and ocean water, also with outstanding heat-resistance without toxic allergy due to lacquer. 
2.Performance of coating: can be solidified into films by high temperature., the coating is smooth and even, flexible and hard, good heat-conductivity, good physical mechanical performance and chemical properties (see table).

Note: period is : normal temperature 16h, norminated temperature 8h. 
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. 
Heat-resistance performance:TH—901 belongsto high temperature-resistant coating, the heat-resistant performance can use for long time within 200℃ , sweeping temperature can not exceed 250℃ /h。 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.
