Reliable fixation of the boat on the water is the key to comfortable fishing and the safety of the crew. Installation of anchor dips on PVC boat is one of the first actions for any owner who wants to expand the functionality of his vessel. Without a well-equipped bow mount, you can not fully use the anchor-cat or cargo, which is especially critical when fishing on the current or in windy weather.
Modern inflatable boats are often equipped with basic elements, but their location or quality does not always suit experienced water-engineers. Self-mounting allows you to choose the ideal point of application of force, avoiding skewed hull when anchored. bolt-bolt Not only does it hold the boat, but it also prevents damage to the cylinders on the side during jerks.
In this article, we will take a look at the entire process, from the selection of materials to the final sealing of the seam. You do not need complex industrial equipment, but compliance with temperature regimes and surface cleanliness will be the decisive factor in success. Errors in the preparation stage can lead to depressurization, so carefully study the theoretical part before starting work.
Selection of the appropriate fastener and tools
The first step is to buy high-quality hardware. The market offers many options, but for inflatable structures, the best solution is a loose bolt with a wide pressing washer. PVCMinimizing the risk of material rupture under the tension of the anchor tile.
Pay attention to the material of manufacture: stainless steel brand AISI 304 or AISI 316 An aggressive aqueous medium, especially salty ones, quickly destroys cheap alloys, turning a reliable fastener into a source of rust and potential leakage. The carving should be clean, without barbs, so as not to damage the fabric when tightening.
You need a specific set of tools to do this, which you want to prepare in advance, and not having the necessary equipment in the middle of the process can disrupt the gluing technology, which is unacceptable.
- ๐ง Electric temperature-adjusted dryer or industrial thermophen
- ๐งด Degreasing agent (acetone, white spirit or special PVC cleaner)
- โ๏ธ Scissors, sharp knife and marker for marking
- ๐งช Two-component polyurethane adhesive for PVC materials
โ ๏ธ Attention: The use of household hair dryers is unacceptable, as they do not develop the temperature necessary to activate the glue and warm the tissue to a state of elasticity.
Buy glue and fabric for patches of the same brand as the boat itself, or check the compatibility with the manufacturer, as the chemical composition of PVC may differ.
Determining the optimal location for installation
Selecting a location for a dim is not just a matter of convenience, it's an engineering challenge. The central rim bolt is usually mounted on the bow of the boat, strictly along the axis of symmetry. Shifting away from the center will cause the boat to turn sideways to the wave or current, which increases the risk of water flooding through the side.
If you plan to install an additional rift to hold the anchor cable in the working position (so as not to etching the anchor every time), it is located closer to the cylinder, but taking into account the passage of the person. It is important to consider the geometry of the bottom: installation in curved areas requires the use of elastic adapters or careful warming up to ensure that the glue falls evenly.
You only mark the entire boat, and when the balloons are blown away, the geometry of the cylinders gets distorted, and once pumped, the installed element can be in an uncomfortable place or create a fold. Mark the center of the hole and the contour of the downpour washer.
Surface Preparation: A Key Stage of Adhesion
The quality of the gluing is 90% dependent on surface preparation. PVC fabric often has a protective layer or factory lubricant that prevents the penetration of the glue. Mechanical and chemical cleaning is required. First, carefully seal the installation site with fine sandpaper (graininess). P180-P240), removing the glossy layer without damaging the thread cords.
After machining, the surface is thoroughly degreased. Rub the area with a rag moistened with solvent, moving from center to edges. Do not allow degrease to hit valves or other elements that are not subject to gluing. Repeat the procedure 2-3 times until the contaminants completely disappear.
Pay special attention to dry surfaces, even microscopic droplets of moisture, condensate or dust that has settled after degreasing, will reduce adhesion to zero, work better done in a room with low humidity and a temperature of no lower than the temperature. +15ยฐC.
- ๐ฌ๏ธ Blow the surface with compressed air after cleaning.
- ๐งค Work in clean gloves to avoid leaving fat marks
- ๐ซ Do not touch the prepared surface with your fingers.
โ ๏ธ Note: Do not use gasoline or aggressive solvents containing chlorine for degreasing, as they can destroy the structure of polyvinyl chloride, making the material brittle.
Technology of applying glue and gluing
The gluing process requires precision and time intervals. Most polyurethane PVC adhesives are hot glued. First, a thin layer of glue is applied to both the surfaces to be glued: the boat fabric and the back of the dim (or patch, if used), the first layer serves as soil and absorbs into the pores of the material.
After drying the first layer (usually 10-20 minutes, depending on the instructions on the tube), a second, basic layer is applied. When the glue stops sticking to the fingers (the "stick test"), the surfaces must be warmed up. The dryer heats the two elements evenly to temperature. 50-60ยฐCThe fabric should become soft and elastic, and the glue should become shiny and active.
The connection is fast and precise: combine the holes and press hard. Roll the glue place from the center to the edges with a roller, squeezing out the air bubbles. Then a downpour washer is placed on the boat and the nut is tightened. The tightening force should be sufficient for a tight fit, but not excessive, so as not to push the fabric.
Sequence of action:1. Apply layer 1 -> Dry 15 min
2. Apply layer 2 -> Dry to "tip"
3. Warm up with a hair dryer to 60ยฐC
4. Connect and pin down
โ๏ธ Control of gluing
Sealing of threaded connection and finishing
Even the best gluing requires additional sealing of the threaded joint, especially if the bolt goes through the fabric. Water can penetrate the threads, causing the adhesive to dissect from the inside. This uses a silicone sealant or a special lubricant that is resistant to water.
Put a sealant on the bolt thread before you install it, and then you can also miss the contour of the washer after you install it, and this creates an additional barrier, and after you tighten the nuts, the excess sealant is carefully removed, forming a smooth burrow around the base.
The final check includes a visual check for skews and a leakproofness test, a pumped boat with a set of crumb can be left for several hours (preferably overnight) to check if the pressure has dropped, and it is also useful to plentifully moisten the gluing site with soap solution and look for bubbles.
What to do if the glue does not dry?
If the adhesive remains sticky for too long, the technology (low temperature, humidity) may have broken or the shelf life has expired, in which case it is better to gently remove the layer with a scalpel, clean the surface again and repeat the process with a new adhesive.
specifications table of adhesive compounds for PVC
The choice of adhesive is critical. Other compounds have different lifetimes, activation temperatures and the resulting strength of the seam. Below is a comparison of the popular types of adhesives used to fit fit fittings.
| Type of glue | Basis | Drying time (min) | Activation temperature |
|---|---|---|---|
| Polyurethane | Two-pronged | 20-30 | 50-60ยฐC |
| Specialized (PVC) | single-component | 10-15 | 40-50ยฐC |
| Rubber glue | nairite | 40-60 | No need to heat up. |
| epoxy | Epoxy resin | 120+ | No need to heat up. |
The best results for the installation of metal elements show polyurethaneBecause it forms a chemical bond with the material, turning into a monolith, the other options may be inferior in tensile strength or elasticity.
Frequent errors and precautions
Failure to comply with technology often causes the pit to break off under load, and one of the most common mistakes is saving time on drying glue, and trying to speed up the process with heavy heating leads to boiling of the solvent inside the seam, which forms pores and reduces strength.
Another mistake is to use narrow washers. PVC fabric tends to stretch under load. If the press area is small, the cloth will just burst out from under the puck, even if the glue holds it perfectly. Always use the widest washers allowed by the fry design.
- โ Ignoring the temperature regime during gluing
- โ Insufficient effort to press the details
- โ Dust entering the seam at the time of connection
- โ Use of the boat ahead of time (full polymerization takes up to 72 hours)
โ ๏ธ Warning: Do not test the strength of the mug by pulling it with your hands immediately after gluing. Complete polymerization of the adhesive takes 24 to 72 hours, and early loading can disrupt the formation of molecular bonds.
Full strength of the adhesive seam is achieved only 3 days after installation, until this time the operation of the boat under load is prohibited.
FAQ: Frequently asked questions
Can I put it on a cold one without a hair dryer?
Technically, some adhesives allow cold gluing, but for the installation of loadable elements (diaper, ducks) this is unacceptable. Hot gluing provides penetration of the glue into the fabric structure and high strength, which the cold method can not give.
How long can I take the boat to the water?
Although the glue is grasped in a few hours, the full load (launch, anchor installation) is recommended not earlier than 24-48 hours, this ensures that the seam will withstand the dynamic jerks of the anchor cable.
What if the rum is torn off along with a piece of cloth?
This means that the glue itself held perfectly, but the load exceeded the strength of the fabric itself, or the wrong installation point was chosen, so you need to put a full-fledged larger patch on top of the damage and transfer it to another place or use a wider distribution plate.
Do I need to drill holes in the balloon?
No, modern technology allows the rim bolts to be attached exclusively to glue, drilling breaks the tightness of the balloon and creates stress points, which leads to rapid destruction, mechanical fasteners (bolt through fabric) are used only in combination with adhesive base and sealant, but not as the main holder.
