Glass steel yacht vacuum adsorption molding method

In recent years, fiberglass yacht manufacturing in China has been a mature process, basically yacht hull, deck, upper deck and flybridge and other large and small accessories are made of fiberglass materials, fiberglass production molding easy, convenient material procurement, low cost, short construction period, bearing strength enough to 95 feet below the yacht manufacturing. At present, the general construction methods of fiberglass steel on yachts mainly include two construction methods: hand paste lamination and vacuum adsorption. Hand paste lamination method is the basic construction method of FRP yachts, most of the best construction method for yachts below 60 feet, construction is not easy to fail, and the appearance of the product is not limited. As the name suggests, it is the use of manual resin and felt and cloth layer by layer of hand paste out, the required period is relatively long. Hull, deck, flybridge and yacht all FRP fittings can use this construction method. Vacuum adsorption method is a relatively new process in recent years, generally used for the construction of fast ships above 60 feet. The construction method is to lay the glass fiber layer on the mold, lay the guide cloth and the guide tube and some auxiliary accessories as needed, cover and fix with plastic film, and then seal with vacuum bag and sealant, and then vacuum the sealed glass fiber layer, and then import resin molding, which is a very effective molding method. And save labor and time, the product weight is light, less bubbles, the amount of resin is also less, the strength increases and so on. However, more disposable auxiliary materials are required, and the comprehensive cost calculation is comparable to the hand paste lamination method. It is certain that the weight of the ship will be relatively light and the quality will be better. By contrast, the weight of the hull can be reduced by the same amount of power and the ship will go faster. Basic materials and equipment for vacuum adsorption: Vacuum using resin Glass fiber biaxial composite felt, continuous felt Vacuum curing agent Release cloth, flow guide net, vacuum bag mold, spray glue, sealing tape, vacuum feed pipe, vacuum suction pipe, winding pipe, tee joint, vacuum leak detector, resin collector and vacuum pump/gas storage tank and other vacuum equipment The basic work flow of vacuum adsorption method: Preliminary work: The mold is finished after cleaning and waxing. The glue shell is sprayed Start the vacuum adsorption workflow: Block the need to open position "composite felt layer" reinforcing material adhesive "Composite felt layer" diversion network arrangement and layout "vacuum bag mold seal" diversion feed pipe/exhaust pipe arrangement and layout "Connecting feed and resin collector installation" Leak test "Open vacuum pump vacuum" Check working condition "product completed Vacuum pumping equipment - vacuum pump/gas holder One of the composite felt paving layers Composite felt layer two 1. Composite felt laying layer It is the layering work before vacuuming, and the composite felt needs to be laid layer by layer using special spray glue according to the requirements of the layering scheme. One of the stiffener adhesives Reinforcement stick two 2. Stick reinforcing material Reinforcing material is the supplementary material for the thickness of the hull, generally using PVC form foam board, according to the requirements of the lamination scheme. 3. Composite felt laying layer It's a laminated felt laid out behind the reinforcement. One of the test leaks after sealing the vacuum bag mold Vacuum bag mold seal after test leakage 2 4. Vacuum bag mold seal After the composite felt is laid out, cover the vacuum bag mold and fix the bag mold with sealant, so as to ensure that there will be no air leakage when vacuuming, and test with a vacuum leak detector until it is completely sealed. Vacuum pump work vacuuming one Vacuum pump work vacuum two Vacuum pump work vacuum three Vacuum pump work vacuum four 5. The vacuum pump starts to work After the sealing test is completed, check the feed pipe/suction pipe and other vacuum system connection, open the vacuum pump to start the vacuum work, and observe the resin import status at any time... If any abnormality is found, deal with it immediately until the resin conductivity is complete. General FRP yacht production of the use of resin; Phthalic polyester resin, m-benzene polyester resin, vinyl resin and epoxy resin. Vinyl resin is used in vacuum adsorption molding in China, and vinyl ester resin has a stretch of more than 5%, tensile strength of 11800 pounds/square inch, its water resistance is greater than phthalic polyester resin and m-benzene polyester resin, and structural strength, not easy to produce bubbles and many other benefits.

A case of an old marina being converted into a marina

China's rivers can run through the urban basin of the coastline of thousands of kilometers, in recent years, rapid urban construction has created the development and beautification of coastal areas, become a good opportunity for the promotion of yacht culture, create people's yacht life and the current consumption power of provincial cities, It is an urgent task to transform hundreds of abandoned marinas into the inland marina Club of the Rhine River in Paris, France, which can be combined with a complete set of marketing services such as yacht display, sales, leasing, leisure and maintenance. In recent years, the vigorous regulation of disorderly sand mining and forest theft in domestic rivers has resulted in the disuse of a large number of small old docks, and it is often seen that there are abandoned docks next to the modern river road, which are not abandoned or temporarily docked by transport ships. In view of optimizing the old docks on the river bank to create Chinese yacht culture, this case is briefly explained. Current status of the old pier Current situation of an old wharf:（Riverside Pier outside the green belt of Jiangbin Avenue) The old pier was 120 meters long The water depth of the pier is 6-10 meters The plot along the river is 120m X 13m A pontoon pier 30 m x 10 m Both tracks are 30 meters long 3 approaches with a width of 5 meters and surrounding green space Reconstruction planning plan drawing Reconstruction plan: · Rebuilt yacht pier and mooring facilities under the old pontoon pier and track can dock dozens of yachts after completion. · A two-story building with an area of 150 square meters will be built on the west side of the long end of the riverbank plot as a marketing center. Indoor reception and display of 6-10 meters fiberglass dinghies, inflatable dinghies 15-20, the second floor as a marketing office. · Build a two-story building with an area of 150 square meters on the east side of the long end of the riverbank plot as a club and maintenance center. Part of the first floor is used as a maintenance center to handle the daily maintenance work of the yacht and the indoor storage of the yacht (equipped with mechanical lifting facilities to store the boat in layers). The second floor is a club for members' activities and exchanges, with a restaurant and conference hall. · An open-air yacht exhibition area 70 meters long near the south in the middle of the riverbank plot can display 10-15 yachts ranging from 6 meters to 10 meters. · Use the original track as the foundation to build self-propelled frame crane facilities, so as to prepare the boat can be lifted up and down in flood season. Club and pier schematic reference Marina trestle design: The design of the trestle is a key facility for the berthing and mooring of the yacht dock, which involves the safety consideration of the yacht berthing. The facilities are designed and constructed by experts imported from abroad. The design of the trestle should be based on the height of the tide and the draft depth of the yacht with the shore topography for the most appropriate safety facilities and water, shore power supply configuration. At present, the original pier has a pontoon pier and two rail piers. The current facilities will be re-planned and designed into a modern yacht pier and trestle to safely dock small and large yachts, creating a new chapter in the riverside waters. Trestle design one Trestle design two Trestle design three 6-10m boats are the most in demand in the river waters market in the future: According to the current popularity of the size of the yacht will mostly be about 6-10 meters, and the price of this type of boat will be between 300,000 and 1 million, which is the budget that the general public can afford. In addition to the riverside land display, it also displays and berths all kinds of yachts and sailing boats on the pier pier pier. The docking of boats on the trestle Clubs and Repair Centers: The east side of the building is built as a maintenance center and club. The maintenance center on the first floor has the function of indoor yacht storage in addition to routine maintenance work, and the club on the second floor serves as a series of service Spaces for members' activities, meetings and catering. Service center and club schematic reference Marina construction: Based on the basic framework of the original pontoon pier and the two track piers, it has been reconstructed into a modern yacht pier, with advanced floating trestle, mooring equipment for yachts to berth, and night lights to create a yacht pier that can be used day and night. After the completion of construction, several large luxury yachts with a length of more than 20 meters and dozens of small and medium-sized yachts can be berthing, becoming a spectacular marina on the river bank. trestle Pier berthing

Teak Deck vs PVC artificial teak deck

For more than 10 years, the Teak Deck can often be seen on high-priced yachts or sailing boats above 50 feet in the United States and Europe, which replaces the traditional Non-skid Deck. Teak deck looks more luxurious and noble even though the cost is several times higher, but there are many yacht buyers like his yacht equipped with this teak deck. The teak deck is mainly installed on the moving lines of the main deck, walkways, stair treads and diving boards, etc. It is the completion of the construction of the teak deck by making a reasonable splice of the long solid teak wood of a certain thickness according to its shape on the deck. The joints are made of black lines with professional vinyl. Teak deck is necessary to have experienced and professional technicians to achieve the perfect construction, in addition to the selection of basic teak strips, special adhesive coating and primer use, according to the various shapes of the deck walkway diving board how to make a reasonable splicing, how to ensure the quality of teak deck and so on are very professional problems. Classification of teak deck materials At present, the teak decks used in the European market in the United States are roughly teak solid wood processing and PVC manufacturing processing teak decks; 1. The deck of teak solid wood processing is made of the best Myanmar teak according to the shape of the deck. The earliest teak deck is the basic configuration of sailing ships at that time, sailing ships are handmade wood, 50-60's fiberglass process has not been popularized, all yachts are made of wood, the deck surface is naturally teak splice, and later slowly developed to the high-priced fiberglass power boat will also use teak solid wood to make deck surface walkway stairs and so on. 2. PVC manufactured artificial teak deck is a new product developed abroad in recent years to replace teak solid wood deck, European and American countries have a few suppliers such as Tek Dek, Flexiteek, DEK-King and other brands. They made the PVC material into a variety of integrated materials as if teak grain and then according to the shape and size of the deck using the computer to cut and bond into several large pieces, and then these semi-finished products on the ship deck glued and installed, the completed PVC deck looks and teak solid wood made of the deck is not easy to separate out. Teak wood deck maintenance Teak solid wood deck surface is only polished teak solid wood strips are not painted, after wind blowing water will inevitably accumulate discoloration and lose the original rich and beautiful texture of teak, to maintain the long-term good state of teak deck must have regular, appropriate maintenance and maintenance. Do not use teak oil, dirty stains will repeatedly be absorbed by the teak oil and stored under the oil. The only way to restore the original golden color and texture of the teak surface is to remove the base layer of the teak surface, which can be done in two ways: one is to use sandpaper to remove the teak surface layer, and the other is to use "teak repair agent" to chemically corrode the teak surface layer. Both methods remove a layer of teak surface, and the thickness of the teak deck will gradually thin as a result. The only best way to maintain the teak deck is to wash it regularly with detergent and seawater, and to find out which brand of foam and cold water can dissolve the detergent most easily. The reason for using salt water is that any water will seep into the teak floor through the cracks in the deck batten and will move to the screws on the side of the floor or into the replenishment material inside, but the conduction of salt water will be less perishable than that of fresh water. If the ship is in fresh water and can make its own salt water to clean, the teak deck will not know how the water is different! If water algae sticks to the teak deck during the winter, it can be cleaned with water mixed with vinegar and easily removed. The well-maintained teak deck has a record of being able to keep it as good as new after 40 years of use. PVC artificial teak deck maintenance PVC artificial deck is a synthetic material of PVC, which can prevent ultraviolet radiation, impact resistance, oil resistance, water resistance and considerable corrosion resistance. Maintenance does not require special methods, as long as daily cleaning can keep the PVC artificial deck in good condition. Comparison of solid teak deck and PVC artificial teak deck Teak solid wood deck and PVC artificial teak deck are not much like teak from the outside, but their materials, construction, cost, use and maintenance are different. Teak solid wood deck is the use of noble teak wood logs through the selection of solid wood bars with similar background color, surface pattern and lines to make the most reasonable and beautiful splice, all the deck planes and walkways with different width and width are best matched

Teach you how to maintain and maintain the battery in the yacht

In general, the battery on the yacht is maintenance-free, but there are still some ways to increase the effectiveness and service life of the battery: Keep the battery fully charged, so that the battery can maintain a longer service life; Check the battery at least every 30 days. The battery connectors and wiring harnesses are cleaned regularly. Check that the battery cable is reliably connected to the terminal. Tighten the terminal nut by hand and then tighten it 1/4 turn with a wrench. Check the electrolyte capacity of each battery in the battery pack. The electrolyte capacity level should be above the scale line. If the liquid level is below the scale, Distilled water is added until the electrolyte reaches the appropriate volume value. Do not overfill the battery box with electrolyte. Keep the battery in a cool, dry place when charging for long periods of time. Use a hydrometer or voltmeter to check the battery level every three months. If the specific gravity is lower than 1.225 or the voltage is lower than 12.4, charge the battery.

How to maintain the exterior of the yacht

The yacht should be wiped with a soft cloth every morning to remove the moisture left by the morning mist, and pay special attention to Windows, stainless steel parts, finished parts and soft cushions used in the open air. Hull and waterline The hull is usually cleaned once a week, or as needed, depending on the water quality of the yacht. Special Marine cleaning fluids can be used to clean the hull, but pay attention to the product instructions when using, as some cleaning fluids may affect the coating on the bottom of the ship to prevent Marine life from attaching. Porthole glass The porthole glass of the yacht can be used with specialized glass maintenance products such as RAIN-X, which has a cleaning and waterproof effect, and can penetrate the glass pores to form a surface protective film, providing a clear line of sight, which can stop the water droplets leaving traces on the glass, so that the window is kept clean every day. cushion Open cushions should be kept as dry as possible. When not in use, it can be wrapped in a padded cover or placed upright in a storage compartment. After a rain or after cleaning the yacht, the cushion will generally get wet, this time to wipe the moisture off the cushion as much as possible to keep it dry. If the cushion becomes dirty or stained, it can be cleaned with a special cleaner. canvas You can use a warm cleaning solution to clean, in wrinkled areas, such as where there are holes, some salt will gather, you can apply petroleum jelly after cleaning, and apply once every 120 days. Transparent plastic window Plastic Windows can be cleaned with water and dried with a soft cloth. When rolling up the window, be careful not to cause scratches, do not let the window remain rolled up for a long time, which may cause discoloration, it is best to roll up during the day and put down at night. Zipper areas are also prone to salt accumulation, can be cleaned every 120 days with a warm cleaning solution. Hatch cover on deck Each hatch cover on the deck has a trough under it to collect and discharge the water that flows into the gap in the hatch cover. After each wash, hatch covers on all decks should be opened, grooves cleaned, and dried. In the case of long-term non-use, it is best to open the hatch cover once a month and wipe the seal strip on the hatch cover with warm cleaning liquid. External latch The latches on deck storage cabinets should be kept clean, tidy and dry to prevent mildew. After each wash, the external storage cabinets should be opened and cooled to dry. Keep the items in the storage cupboard dry and neatly arranged. It is best to empty the storage cupboard every 120 days and clean it thoroughly. All exterior locks, latches, and hinges should be kept clean, dry, and preferably replaced annually. Latches and hinges should be lubricated every six months. Yacht exterior cleaning Whether the yacht is cruising or moored at the dock, it will be contaminated with stolen goods, dust, bird droppings, and the crystalline layer of salt left after the evaporation of the sea water on the yacht, these substances have a certain destructive effect on the surface of the yacht gelcoat, so after each use of the yacht, it is necessary to clean with fresh water, if not used for a long time, at least once a week. When cleaning the yacht, choose the appropriate cleaning liquid according to the actual situation of the yacht. Use your hands to wipe the surface of the yacht, if it is not dirty, simply rinse and dry with fresh water. When choosing a cleaning solution, you should choose a neutral cleaning product specifically designed for yachts. Inappropriate cleaning solutions may reduce the life of gelcoat or paint. When cleaning a yacht, it should be washed from high to low, from the bow to the stern. Because most yachts are designed to drain this way. After the cleaning is completed, it is very important not to let the cleaning liquid or water remaining in the hull after cleaning dry in the sun. Residual cleaning fluid can dirty the hull quickly, and residual water often leaves patches of water that are difficult to remove. Therefore, after each cleaning of the hull, the hull should be flushed with fresh water and quickly dried. Exterior hardware The stainless steel parts outside the yacht, although it is designed for use at sea, but because the sea environment is worse than the land, these stainless steel parts still need a better wax layer protection. Stainless steel should be waxed every 60 days or as needed. High-quality wax film can resist the erosion of seawater, increase gloss, and make future maintenance easier. External electronics When washing the boat, all external electronic devices/buttons and consoles should not be washed with water, otherwise it will damage the internal electronic components. Can be wiped with a damp cloth. Every week, all electronic devices are turned on and run for at least half an hour to remove moisture from the line.
