Special Anti-corrosion and coating HL—9068coating(HAILIN system)
   Using scope of coating    

1. Carbon-steel heat-exchanger, carbon-steel water cooler, re-boiler tube, air cooler or other non-style heat exchanger. 

2.Designing working temperature is 300℃, long time working temperature is within220℃.

   Implementation standards    
SH/T3540《producing and inspection rules for complicated coating of tube of steel heat-exchanger》
   Suitable coating material      
1.Freshwater, salt water, ocean water, industrial recycling water, distilled water and vapor. 
2.Weak acid medium and alkaline medium, sulphur medium, hydrogen sulfide medium, can resistant with vapor purge. 
3.Gasoline, diesel oil, solvent oil, crude oil, engine oil, vacuum pump oil and other oil-water high temperature exchanger.
   Technical property of coating     
1.Coating ingredients: HL—9068anti-corrosion painting is transit from Chinese raw painting, with function of acid, alkali and salt resistance, meanwhile with outstanding heat and oil resistance, without toxic allergy because of Chinese lacquer. It’scomposed with anti-corrosion thermal conductivity pigment, anti-precipitation, plasticizer and catalyst. 
2.Coating performance: solidified to be film in high temperature after painting, the painting surface is average, flexible and hard, good thermal conductivity, good mechanical performance and good chemical performance.

1.Good thermal conductivity, good effect of anti-dirt. Measuring 150±30μm,thermal resistance is only1.85×10-4㎡ .h.℃ .kcal, because the tube can no longer produce rust with high thermal resistance, the efficiency of heat exchange improves greatly. 
2.Performance of Thermal resistance HL—9068belongs to high temperature resistant painting, and its function can be used for a long time at 200℃ sweeping temperature can not exceed 250℃ /h. 
3.Inspection index of coating quality. 
A.Apperance inspection: the surface should be clean, no foreign matters, no bubbles, no flow, the color and the sense should be in accordance. 
B.Thickness of coating:According to the standard SH/T3540, it can be divided into two levels. Normal dry film thickness is 150±30μm( for normal equipments), strengthening dry film thickness is 250~300μm(for chemical equipments with serious corrosion and scaled). 
C.side leakage of coating testing by electrical spark, painting if leak point of film is found. 
D.Monitoring of painting film: mechanical collision or flexible friction should be avoided in the process of storage and transportation and disassembling 
repair before using and installation.
