Problems solved by technology

[0002] The propeller is an important part of the ship, which is submerged in seawater all the year round. In order to prevent seawater corrosion, the propeller is mostly made of copper alloy material, and its cost is very high. Changes have a certain impact on the working efficiency of the propeller. If it needs to be replaced, not only the docking cost and repair cost are high, but the cost of the propeller itself is relatively expensive, and the total cost required is huge
At present, propellers with low cost and resistance to seawater corrosion and impact are still rare

Embodiment Construction

[0010] figure 1 Among them, the propeller 1 is made of steel material. After derusting and roughening, a number of uneven micro-pits are formed on the outer surface of the propeller 1 (the micro-pits are not shown in the figure). After coating epoxy resin 2, epoxy Resin 2 penetrates into several micro pits, and forms an epoxy resin protective layer that is not easy to peel off after curing. Due to the good chemical stability and impact resistance of epoxy resin, the epoxy resin protective coating can effectively resist the impact and corrosion of seawater , so that the propeller 1 can work stably and efficiently for a long time.

[0011] figure 2 Among them, the propeller 1 is made of steel material. After derusting and roughening, a number of uneven micro-pits are formed on the outer surface of the propeller 1. An interlining 3 is set between the propeller 1 and the epoxy resin 2, and the epoxy resin 2 penetrates into it. In several micro pits, an epoxy resin protective la...

technical field [0001] The invention relates to ship fittings, in particular to the improvement of propellers. Background technique [0002] The propeller is an important part of the ship, which is submerged in seawater all the year round. In order to prevent seawater corrosion, the propeller is mostly made of copper alloy material, and its cost is very high. Changes have a certain impact on the working efficiency of the propeller. If it needs to be replaced, not only the cost of docking and repairing is very high, but also the cost of the propeller itself is relatively expensive, and the total cost required is very huge. At present, propellers with low cost and resistance to seawater corrosion and impact are still rare. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a propeller resistant to seawater corrosion, which can effectively resist the impact and corrosion of seawa...
