Abstract
The utility model aims to provide a corrosion resisting blower. The utility model is characterized in that one or more parts of the outside surface the inner wall of a pipeline of a blower (1), the outer wall of the pipeline, an impeller and a blade are provided with a fusing combining epoxy powdery coating layer (2), and the thickness of the fusing combining epoxy powdery coating layer (2) is between 0.3 mm and 1.2 mm. In addition, the epoxy powdery coating layer (2) has the characteristics of stable chemical property, oil resistance, acid resistance, alkali resistance, resistance of sea water corrosion, strong adhesive force, high resistance to impact, etc.
Description
Technical field:
The utility model relates to blower fan, especially a kind of corrosion resistant fan.
Background technique:
Blower fan is the device that often adopts in the exhaust and the engineering of supplying gas, and row, when sending the gas of corrosive materials such as containing oil, acid, alkali, salt, the pipeline and the blade of blower fan is had certain corrosive action.Adopt thick-walled structure and stainless steel material for corrosion protection, this makes cost too high.
Summary of the invention:
The purpose of this utility model is to provide a kind of corrosion resistant blower fan, it is characterized in that one of inner-walls of duct, pipeline outer wall, the impeller of blower fan (1), appearance of blade are located or many places are provided with smelting combined epoxy powder coating layer (2), thickness is 0.3～1.2mm.
The optimum thickness of the utility model floating coat (2) is 0.5～0.8mm.
Anticorrosive paint layer used in the utility model is the commercially available prod, and as the SEBF anticorrosive paint of Metal Corrosion and Protection Inst., Chinese Academy of Sciences's development and exploitation, it has following characteristics:
1 stable chemical performance, oil resistant, acidproof, alkaline-resisting, seawater corrosion resistance.
2 strong adhesions, excellent in cushion effect.
3 abrasion resistance properties good (in corrosive environment) are five times of cast iron.
4 serviceability temperatures are extensive, are-40～150 ℃ in the air, are 0～100 ℃ in the solution, in the seawater 〉=and 100 ℃ (because experimental condition is only done seawater＞110 ℃ experiment).
5 anticorrosive coat thickness ranges are at 30～3000 μ m, can carry out car, mill, machining such as plane, mill.
6 anticorrosive coat even compacts, smooth smooth, resistance is little, the efficiency of transmission height.
7 anticorrosive coats are nontoxic, tasteless, pollution-free.
8 long service life (according to the foreign data introduction, similar anticorrosive coat, safe operation is more than 30 years), price performance is much better than other process for protecting.
A layer thickness is anti-corrosion uniformly, wearing layer owing to employing high-performance adhere, thermosetting epoxy powder form at the metal surface of Fan pipeline, impeller, blade melting and solidification for the utility model, makes pipeline, impeller, blade have stronger wear-corrosion resistance.Overcome the shortcoming of blower fan corrosion resistance difference under the occasion of discharging, carrying the gas that contains Korrosionsmedium in the past, enlarged the scope of its application.Such blower fan corrosion-resistant coating has high mechanical strength and impact resistance, good anti-corrosion, wear-resisting property, and prevent electrochemical corrosion.The utility model can be widely used in oil, chemical industry, electric power, shipbuilding, cement, food sanitation and pharmaceutical industries.
