Installation of anchoring is one of the most popular operations for tuning inflatable boats, which allows you to significantly improve the comfort of the vessel. Many owners of budget models or boats of previous years of release face the lack of a standard anchor anchor on the nose or stern, which forces to look for alternative ways to fix the torch. Self-patching of the flame is a regular procedure available to any boater with a minimum set of tools and accuracy in operation.
A well-constructed installation ensures that the fastener will withstand severe stress in chop and will not come off at the most inopportune moment, maintaining the tightness of the cylinders. The process requires strict adherence to surface preparation technology and temperature regime, since it is these factors that determine the adhesion of the adhesion of the adhesive to polyvinyl chloride tissue. Ignoring the nuances of working with the polyvinyl chloride. double-component It can lead to the fact that the pome will peel off through several fishing trips, so the choice of materials must be approached responsibly.
In this article, we will take a detailed look at the entire process, from choosing the right installation site to the final seam check, so that you can get the job done the first time and forget about the problem of finding a place for an anchor rope. fitting It will be a reliable helper, not a source of potential leakage.
Selection of installation site and surface preparation
The first and critical step is to determine the optimal mounting point that will ensure usability and minimal impact on the boat's performance. Usually, the rimmer is set strictly on the diametric axis in the bow of the cylinder or on the transom if you want a stern mount for trolling or anchoring from a drifting anchor. It is important to consider the geometry of the balloon: the surface must be flat, without strong curves and folds, so that the contact area of the glue is maximum.
Before starting work, you need to carefully clean the installation area of dirt, fat, oxides and factory lubricant, which inevitably reduce adhesion, using a special cleaner or degreasing agent based on acetone or ethyl acetate, which does not damage the structure of PVC, but effectively removes contaminants. Never use gasoline or aggressive solvents of unknown composition, as they can disrupt the chemical structure of the polymer, making it loose and unsuitable for gluing.
After degreasing, the surface should be cleaned with an abrasive material, creating micro scratches for better adhesion of the glue to the fabric. Perfect sandpaper with graininess P120-P180 or special abrasive sponges that do not leave deep furrows. Movements should be circular, extending beyond the future site of glue to ensure a smooth transition and no steps.
⚠️ Attention: After cleaning, it is strictly forbidden to touch the prepared surface with your hands, since the skin fat will instantly reduce the quality of gluing. If you accidentally touch the gluing site, the degreasing and cleaning procedure must be repeated.
Some models of riym require additional leveling of the site if the balloon has a pronounced curvature. In such cases, masters often use the method of pre-cooking of the patch-base, which creates a flat platform for mounting fittings. This is especially true for boats with narrow cylinders, where the bend radius is large, and the flat base of the riy cannot fit tightly with the entire area.
Essential tools and supplies
A good anchor ditch installation will require not only the fastener itself, but also a specific set of tools that are not necessary to achieve the factory quality of the connection. The main component is a special glue for PVC, which, after polymerization, forms a monolithic compound, effectively welding materials at the molecular level. The market offers many options, but professionals prefer two-component polyurethane compounds, such as: Texacol or Desmodurwhich provide high elasticity and strength of the seam.
In addition to the glue, you will need a brush to apply the composition, preferably with a rigid bristles that will not leave the villi on the surface. To uniformly distribute the glue and remove air bubbles, a roller is often used, and to fix the position of the parts - loads or a special press roller. Also remember to prepare a dryer for heat treatment, since the activation of the glue and warming up the fabric are mandatory stages of the technology.
List of necessary materials and tools:
- 🛠️ Two-component glue for PVC (base and hardener in the correct proportions).
- 📏 Marker and ruler for accurate marking of the installation center.
- 🌡️ Industrial dryer with temperature adjustment for heating the fabric.
- 🧽 Degreasing and rags without pile to prepare the surface.
- ⚖️ Scales for precise mixing of glue components (if not in ready-made proportions).
Special attention should be paid to the choice of the mug itself: it must be made of durable plastic or composite materials resistant to ultraviolet and sea water. Cheap Chinese counterparts are often made from fragile plastic that bursts at the first serious load or in the cold, so save on this element is not worth it. Metal pogs are less common due to the risk of corrosion and tissue damage, but if you choose this option, make sure that all sharp edges are carefully rolled.
When mixing glue, strictly observe the proportions specified by the manufacturer. Excess hardener will make the seam brittle, and the lack will prevent the adhesive mass from gaining full strength.
Adhesive technology: step-by-step process
The process of pasting the stain begins with the preparation of adhesives, which must be mixed immediately before application, since its life is limited. After mixing the components, the adhesives are applied in a thin, uniform layer on both glued surfaces: on the cleaned area of the balloon and on the base of the stain. It is important to avoid skips and puddles, the layer must be thin and uniform to ensure maximum contact area.
After the first layer is applied, it must be allowed to dry to "stick" for the time specified in the instructions (usually 10-20 minutes), then the second layer is applied. The second layer is the main working layer, and it also needs to be dried, but before the glue stops sticking to the fingers, but retains stickiness. At this point, the glue is activated with a hair dryer: the surfaces are warmed to a temperature of 50-60 degrees Celsius, which makes the glue glossy and ready to join.
☑️ Checklist of the gluing process
The connection of the parts should be fast and accurate, because after contact of heated surfaces, the time for correction of the position is minimal. The rhyme is applied to the marked place and tightly pressed, after which the connection must be carefully rolled from the center to the edges, squeezing out the residue of air. The pressure must be uniform and strong enough to ensure tight contact of the glue with the fabric throughout the area.
The table below shows the main parameters of the gluing process for different types of glue:
| Parameter | Polyurethane glue | Chloroprene glue | single-component glue |
|---|---|---|---|
| Time to dry the layer | 15-20 minutes. | 10-15 minutes. | Depends on the temperature. |
| Activation temperature | 50-60 °C | 80-90 °C | Not required |
| Strength of the seam | High. | Medium | Low. |
| Elasticity | High. | Medium | Low. |
After rolling, the product must dry at room temperature for 24-48 hours before gaining initial strength, full polymerization and maximum strength occurs in 3-7 days, depending on the humidity and ambient temperature, during which time it is strictly recommended not to operate the boat or load the sack.
⚠️ Warning: Do not try to speed up the drying of the dimp with a hair dryer or heaters after gluing. Sharp heating can cause the foaming of the glue or the formation of bubbles, which will lead to the failure of the compound.
Features of working with different types of PVC tissues
PVC boat fabrics can vary significantly in the composition of the upper protective layer, which affects the bonding technology. Valmex or PVC 1100The thick tissues absorb the glue worse, so it is important not to over-stitch the layer on the drying, otherwise the adhesion will be weak.
On the other hand, softer and thinner fabrics, often used in rowing boats, require care when working with a hair dryer, so as not to overheat or deform the balloon. In such cases, the temperature of the hair dryer should be set at the minimum necessary, and warm up to produce rapid movements. Experienced craftsmen recommend doing a test glue on a cloth clip or on an inconspicuous section of the boat (for example, under a trench) to find the ideal mode.
The color of the fabric can also play a role: dark cylinders heat up in the sun faster, which must be considered when planning work in hot weather. If the boat has just been in direct sunlight, it must be brought into the shade and allowed to cool to room temperature, otherwise the glue can boil or too quickly grasp, before having time to penetrate the structure of the material.
What to do if the glue dries too quickly?
In hot weather (>25°C), the lifespan of the glue is shortened, add a little less hardener (5-10% less than normal) to slow down the reaction, or cook the glue in smaller portions.
Typical errors and ways to fix them
One of the most common mistakes is that the surface is not properly prepared, when the master neglects to clean or degrease, and as a result, the pome is only kept by the friction and surface tension, falling off at the first load, and if you notice that the glue is not sticking to the fabric or rolling into droplets, then the surface is poorly prepared or the wrong solvent is used.
Another common problem is the formation of air bubbles under the glue, which is due to poor quality rolling or too fast application of the second layer. Bubbles are stress concentrators and points of detachment, so they are unacceptable. If the bubble is found after drying, you can gently prick it with a needle and inject a little fresh glue into it, then press it back with a load.
Mistakes in mixing components, such as a violation of proportions or insufficient mixing, cause the glue to remain sticky forever or become brittle glass. Polymerization It's a chemical reaction that requires precision, so you have to use measuring cups and scales, and if the glue is sticky after drying, you probably don't have enough hardener, and you'll have to remake it, completely removing the old layer.
- ❌ Use of past-life glue (hardener could crystallize).
- ❌ Attempt gluing at a temperature below +15 C (reaction will not go).
- ❌ Lack of fixation of parts with cargoes during the primary grasping.
- ❌ The ingestion of moisture or dust between the layers of glue during a pause on drying.
Quality control and operating rules
Once completely dry, you need to do visual and tactile quality control of the work done, and the seam should be smooth, without bloating, detachment or sticky areas, and try to gently, without fanaticism, to swing from side to side: if you feel movement or hear a crackling break, then the adhesion is not enough and you need to rework.
In the first weeks of operation, it is recommended to avoid extreme loads on the new fry, allowing the connection to finally stabilize. When storing the boat in a rolled-up state, it is desirable to prevent the formation of sharp cloth cloth directly in the glue area, although a quality seam should withstand standard blow-in and inflatation cycles without problems.
High-quality glued rum withstands a load on the breakup of up to 100-150 kg, which is more than enough to hold the anchor even in strong current and wind.
Regularly inspect the condition of the redhead before each season: the absence of cracks on the plastic and the integrity of the glue seam ensure your safety on the water. If you notice the beginning of the detachment of the edges, immediately repair, cleaning and gluing the problem area, without waiting for a complete breakaway.
Can I put a cold coat on the floor without a hair dryer?
Technically, some adhesives allow gluing without heating, but the strength of such a joint for an anchor ditch will be critically low. The anchor rhym experiences dynamic jerking loads that the cold seam is likely to not withstand. The use of a hair dryer and activation of the adhesive is a prerequisite for creating a reliable connection.
How long can you put the boat on the water after gluing?
The minimum drying time is 24 hours at a temperature of +20 ° C, but to gain full strength, it is recommended to wait 48-72 hours. Descent into the water before this time can lead to soaking of the outer layer of the glue and loss of leakage.
How to remove an old rum if it has come off?
The residues of old glue must be mechanically removed (neatly cut with a blade) and cleaned to a clean fabric. If there are glue particles left on the fabric, they can be softened with a special glue remover or gently warmed with a hairdryer and removed with a spatula, after which you need to degrease the surface.
Which glue is better for black or colored PVC?
The color of the fabric does not affect the choice of glue brand, the chemical composition of PVC is important. However, for dark fabrics, you need to be careful with the temperature of the hair dryer, since they absorb heat more strongly and can overheat faster than light analogues.
