How to maintain FRP fishing boats?
FRP is a new shipbuilding material and an important part of modern material innovation. FRP has not been used in shipbuilding for a long time, but it has shown its strong vitality and broad development prospects. FRP ships include not only small boats, such as fishing boats, yachts, high-speed passenger ships, business boats, traffic boats, speedboats, lifeboats, painted boats, sailboats, sports boats, minesweepers, etc. Careful preservation and maintenance of fishing vessels can reduce the loss and extend the service life of fishing vessels. Now many fishing boats use FRP materials. Let's take FRP fishing boats as an example to share the maintenance secrets. Glass fiber reinforced plastics (FRP) is a kind of

Jiangmen shipyard: common causes of hull corrosion
1. Corrosion of the hull structure on the water, the part on the water of the hull mainly includes the deck, superstructure and freeboard. The above water parts of these ships are mainly affected by rain and snow, sea water spray and ocean atmosphere, and these factors are the important reasons for the severe corrosion of the hull on water. In the marine atmosphere, there are a lot of nitrogen compounds, which make the condensation water aggravate the damage to the hull structure. On the other hand, the high temperature of the engine room and boiler in the deck also aggravates the water damage in these areas to a certain extent. Some scientific experiments have shown that,

Jiangmen fishing boat building factory: what harm do marine attachments do to the ship
We know that the sea water has strong corrosivity to the ship, and the marine life has strong adhesion to the ship. After the ship is launched for a period of time, a lot of barnacles, algae and other marine organisms will be attached to the hull, and rust spots will appear. On the other hand, the presence of these warships increases the speed of the ship's flight and, on the other hand, increases the resistance of the ship's flight. Marine attached organisms refer to the animals, plants and microorganisms that grow on the bottom of the ship and on the surface of the equipment in the sea. Microappendages include bacteria, diatoms, protozoa (unicellular animals), rotifers and

Jiangmen fishing boat construction factory: which fishing boats should be distinguished from?
Fishing vessels can be divided into marine fishing vessels and inland fishing vessels according to different working waters. (1) marine fishing vessels. Marine fishing boat is a kind of vessel used to capture aquatic economic animals and plants in the ocean. According to the operation mode, it can be divided into trawler, purse seine, tension net, fishing boat, gill net, etc. The requirements of seaworthiness of marine fishing vessels are high. In order to increase the time of marine operation, the ship should have satisfactory fish tanks and fuel tanks; besides the equipment required for satisfactory flight, special mechanical equipment and instruments should also be provided. Large scale marine fishing vessels are equipped with freezing and catch processing equipment, and their speed is high

Jiangmen fishing boat factory: what is the gap between wooden fishing boat and steel fishing boat?
According to the raw materials of fishing vessels, fishing vessels can be divided into steel fishing boats, wooden fishing boats, glass fiber reinforced plastic fishing boats, steel wood mixed fishing boats, steel mesh cement fishing boats and other raw materials fishing vessels. Next, we will first introduce the differences between wooden fishing boats and steel fishing boats. Wooden fishing boat is made of wood as the primary material. Compared with the fishing boat made of steel, there are many shortcomings: wooden boat will become heavier with time: because of the water absorption of wood, the center of gravity of the fishing boat will be skewed due to the drying of wood when the fishing boat is just made. After using for a period of time, the fishing boat will fly for a period of time, and the weight of the boat will be large after absorbing water from the wood The range has increased,

Jiangmen shipyard: technological process of modern shipbuilding
Ship Lofting linear lofting: the craft lofting and the machine (computer) lofting are divided into craft lofting and machine (computer) lofting. The craft lofting is generally 1:1 share. The sample platform needs to occupy a large area, which needs more manpower and material resources for shipbuilding, and is less selected. Machine lofting, also known as mathematical lofting, relies on advanced technical software to loft the hull, with high accuracy and no occupation of field And manpower, more extensive selection of machine lofting. Structure lofting and unfolding: lofting and unfolding of each structure, making corresponding processing template and sample bar. Cutting sketch: make corresponding cutting sketch.
