Wherein, base-material is the fused solution of phosphatic modified water glass, chlorosulfonated polyethylene, zinc, and its mass ratio is respectively 10～15: 15～25: 2～5.
Heat-transfer effect was preferable when described coat-thickness was 2～80nm, heat-transfer effect the best when thickness is 45nm.
Added tensio-active agent in the coating of the present invention,, coating has been applied evenly easily at tube-surface, improved the coil surface quality to reduce the surface tension of coating.Tensio-active agent among the present invention is an aniorfic surfactant, for example alkylsulfonate or sulfuric acid etc.
The fused solution of phosphatic modified water glass, chlorosulfonated polyethylene, zinc ratio the best in quality was respectively 10: 15: 3.
Evaporative condenser anti-corrosion anti-scale heat conducting coating of the present invention can be used for various metal materials and tubular coil pipe, as bronzing pipe, carbon steel light pipe, carbon steel twisted tube etc.
The coating method of coating of the present invention can be existing method in common, as pickling process, spraying method, spread coating, magnetron sputtering method etc.; The tubing of coil pipe can be copper, steel, titanium etc., tubular common light pipe or all kinds of special-shaped enhanced tube of can be.
The utility model has the advantages that:
1. the fused solution good heat conductivity of the zinc that adds of this coating has improved the heat exchange efficiency about 10%～30% of evaporative condenser;
2. the phosphatic modified water glass in this coating has effectively suppressed coil pipe and has been corroded, and has prolonged the work-ing life of evaporative condenser;
3. this coating has been added chlorosulfonated polyethylene, has fine and close molecular structure, and wear resisting property is strong, and frictional coefficient is little, and surface energy is low, thereby has effectively suppressed the coil surface fouling, has improved heat transfer efficiency, has prolonged work-ing life;
4. nontoxic, tasteless, the nonirritant volatile matter of this coating, the no three wastes;
5. this kind of evaporative condenser coil pipe application nano coating has really played energy-conservation and effect environmental protection;
6. evaporative condenser coil surface anti-corrosion anti-scale heat conducting coating of the present invention is a base-material with the fused solution of phosphatic modified water glass, chlorosulfonated polyethylene and zinc, the good antiscale property characteristic that has kept anticorrosive and anti-oxidant, the chlorosulfonated polyethylene of phosphatic modified water glass has kept the good thermal conduction characteristic of the fused solution of zinc again.
