FRP fishing boats are superior to steel boats and wooden boats in terms of performance and strength, which is well known. In addition, it is also known that it is expensive to build. However, if the price of aquatic products is expensive, it may still be cost-effective even if the ship price is higher.
The design of FRP fishing boatsThe design of FRP fishing boats is different from steel boats and wooden boats. Steel boats and wooden boats are made of steel and wood that are cut, processed, welded, nailed or bolted, and FRP fishing boats are made of materials such as glass fiber and resin. Therefore, it is convenient for design and selection, but due to different materials and process conditions, the strength of the hull varies greatly. This is an issue that needs to be taken into account in the design process.
Because the FRP ship is lighter than the steel ship, the same horsepower of the main engine installed on the FRP ship can be faster, and the fishermen must force the boat to drive in bad weather, at this time, if the hull strength, especially the local strength is not enough, there may be a breakage accident. Because of these situations, new issues are added to the design.
2. The material of FRP fishing boatThe resin material used in the construction of FRP fishing boats can only be stored for 3~6 months, and its performance and material should be changed due to the temperature difference between cold and summer. As a result, it is important to prepare materials only before accepting orders and starting construction, rather than buying more for storage when materials are cheap.
The resin materials and solvents are not only dangerous goods, but also need to be paid special attention in health care, and even more care should be taken in handling and use.
3. Laminating operation of FRPAlthough some people think that the operation of FRP cladding is relatively simple, as if anyone can do it, and women and the elderly can also do it, it is actually not so easy.
FRP is a product that is cured with the help of chemical reactions, but if the process conditions are not suitable, some even do not cure. Thus requiring excellent engineering and technical personnel to carry out careful management. The content of management is multifaceted, and it should be strictly implemented according to certain process conditions.
4. The hull of the FRP fishing boatThe hull of the FRP fishing boat in our country is generally designed in accordance with the steel ship specification, and its rigidity is larger, so that it can not be said that the characteristics of the FRP material are fully exerted, and the materials used are more than the actual demand, and the purpose of saving resources can not be achieved from the current situation. It is necessary to strengthen the design research of FRP characteristics, so as to give full play to the unique advantages of FRP.
5. Delivery of FRP fishing boatsIt takes more than a month for FRP products to reach full curing. Depending on the situation, it may take longer. Therefore, do not go to the fishing ground immediately after the completion and launch of the FRP fishing boat, and verify whether it has reached sufficient strength before delivery. Although under normal circumstances, it is not dangerous to go to the fishing ground immediately after the completion of the launch, but for the sake of safety, it is better to verify that it is safer.
