Pentacryl for wood - characteristics
Wood is a beautiful and noble material ... But the fibers are highly susceptible to changes over time, and the processes that take place in wood, which irreversibly lead to destruction.
Stabilization of wood makes it possible to preserve its original qualities.
Due to such manipulation, destructive processes in the fibers of materials will be fully stopped, and moreover, it gets a more beautiful appearance.
The goal of stabilization is to try to keep the wood from moisture. The material is processed with a special composition that makes the fibers stronger and stronger.
In industrial volumes, this method of stabilizing wood is almost never used, because in large volumes the processing cost is high. As a result of the action of a special solution, internal processes in a piece of wood stop, and it becomes more durable, and the fibers will undergo polymerization.
Compounds that act on the surface of the material clog the pores and fill the void between the fibers. By the way, not all wood is suitable for stabilization.
The following breeds will be perfectly amenable to processing:
Some tree species undergo stabilization, and it is important to process them under pressure:
- Walnut and other wood species by density.
Ebony and amaranth are stable to stabilization and should not be treated with this treatment.
The main process that underlies the transformation of the material is the filling of wood pores with a special composition. The nuances of the technological type may differ depending on the agent used. Polymerization is carried out by means of a varnish in a vacuum or other composition, and the effect can also be achieved by impregnating the material with oils and resins.
Most often, compositions are used that have a high ability to polymerize. The most commonly used oils, polymers, resins or paints and varnishes.
Separately, it is worth considering the characteristics of Pentacryl, but this is a little later.
Natural oils (eg linseed) can also be used as a stabilizer.
Processing by means of "Anacrol-90"
The container in which the timber or wood product will be placed should be fully filled with the composition. Further, vacuum conditions are obtained in a special chamber. The impregnation process is accompanied by the release of air bubbles, and this indicates the ingress of the composition into the wood and pushing the air out.
After the "bubbling" effect disappears, it is important to hold the workpiece in the solution for about half an hour under pressure.For such purposes, you can use a special pump or compressor. After completing all the processing steps, you need to repeat the process, but not earlier than 1/2 hour later. The detector of the completion of the filling of the fibers with a polymer-type composition is the loss of the wood's own "floating" properties. If the product floats up in a container filled with a solution, it means that the filling of the pores will not go through to the end, and the process must be repeated.
The final chord will be drying at a temperature that is close to +100 degrees. If pigment is added to Anacrol-90, it will give an interesting effect of flowers on the wood after the process.
A product for home use, which has a low cost. After treating the wood with such a composition, an additional protective film appears on its surface, which will prevent various dyes from penetrating inside. Most often, the composition is used in order to stabilize the sources for decorative products that will come into contact with aggressive chemical reagents.
The composition reliably protects against fungus, including mold, and also protects against high temperatures, exposure to moisture and ultraviolet rays.
This product is used for all types of wood, with the exception of conifers. When stabilizing the bars, it is important to pay attention to the fluidity of the solution, and the filling of the wood pores will directly depend on this property. It is better not to use a very thick composition, or dissolve it with alcohol. When the resin is heated in a vacuum, it can boil, and therefore the entire process will require observation.
To obtain such a composition, you just need to dissolve 1 tablespoon of salt in 1 liter of water. The method of processing with such a tool is less expensive, but more laborious. For stabilization, wood must be boiled in a saline solution for at least 2 hours.
The most harmless and environmentally friendly composition that does not emit toxins when heated. Moreover, the juice will be an excellent polymerizer.
To ensure deep penetration of the composition for stabilization deep into the wood, the process should be carried out in a vacuum-type chamber, and the processing should be completed in a drying chamber or oven, and the temperature should be +90 degrees. Another advantage of birch sap is that it can be easily mixed with natural dyes.
This substance is optimal for stabilizing wood, which is intended for various crafts, as well as pieces of furniture and decorative elements for outdoor installation. The required viscosity of drying oil can be obtained by adding solvents to it.Alkyd and composite mortars are used for wood, which will be used for the external appearance of the cladding, and drying oil based on components of natural origin is more suitable for stabilizing furniture and decorative elements.
Please note that polymers act quickly, because they can fill the pores of materials to the maximum in a short time. They are used to treat wood using a vacuum. Some types of solvents can even be used at home.
It is a polymer-type composition with a low viscosity level, which can quickly enter wood pores, filling even the smallest voids ..
. Due to optical pigments in the composition of the product, the treated material receives a more saturated fiber pattern.
It is required for stabilization in vacuum chambers. The main active component of the solution is polyester, which is converted into a polymer under the influence of high temperature. The composition will ensure the resistance of the treated wood to chemical reagents, as well as mechanical effects.
Composition is a medium viscosity solution that contains polymers that can change their density when exposed to heat. This tool is popular for both industrial and domestic use. The polymer is supplied in tin cans, which are convenient for transportation and storage.
There is such a remedy like Pentacryl for wood. It is safe for domestic use because it does not contain toxic substances.
At the same time, it penetrates deeply into the wood structure, and also saturates the fibers through fat-soluble pigments, which make the pattern brighter and more expressive. The composition is made on the basis of alkyds.
Processing materials using polymers requires additional devices. The main equipment for stabilizing wood will be a vacuum chamber and a drying cabinet.
The vacuum chamber can be assembled at home using a vacuum pump, plastic containers, valves and tubes, a pressure gauge and a compressor.
An oven can be used instead of a drying cabinet, but here one should take into account the volatility of paints and varnishes under the influence of temperatures and provide excellent ventilation.
Material properties for stabilization. Wood that has undergone such processing, receiving new qualities:
- Resistance to moisture.
- Immunity to chemicals, including aggressive organic substances.
- High strength.
- Long term of application.
- Resistance to temperature changes and humidity.
- Resistant to UV radiation, and there is no burn-in effect yet.
- Preservation of the integrity of the structure with a short contact with open fire.
In this case, the wood that is stabilized will retain its original color (provided that no pigments are used) and shape.
Despite the increased density, the recovered material can be machined to shape it to the desired shape. It lends itself to sawing, cutting, grinding, grinding and polishing.
Wood processed in this way will become similar in strength to stone, and also in structure. This is not just a structural advantage, but also a decorative one. This method of stabilization can rightfully be considered one of the most effective.
Due to the deep impact on the fibers, filling the pores and the common internal space with polymers, the entire structure will be treated. This effect cannot be achieved by other methods, for example, with a surface varnish layer, which will only protect the top layer.
The use of technology
We have already considered the means for processing, and the best is the Pentacryl primer-enamel, and now let's talk about the stabilization method for strengthening the wood. Usually they stabilize the material that is intended for the manufacture of pieces of furniture, the creation of decorative items, toys, crafts and the creation of handles of knives, tools and other products.
Method of stabilization at home
You can also strengthen wood with your own hands, without using special equipment.
The process of processing by means of epoxy resin
The technology will have its own characteristics, and the process itself will be similar to everything described above. But the key indicator that should not be allowed is the boiling of the resin in a vacuum. If such a moment is missed, the wood will be damaged. The epoxy will have a high viscosity and therefore must be diluted with alcohol, which is time consuming. The process itself requires a lot of time and careful monitoring of the process.
Oil type of impregnation
The most popular method of stabilizing wood at home, because it does not require additional equipment and will be cheaper than processing with specialized polymers. Almost any oil is suitable for storing wood - tung, sesame and walnut. Stabilization with linseed oil is widely popular because its price is higher. This is capable of not requiring exposure to high temperatures and is called "cold impregnation". For this reason, it is suitable for stabilization at home.
It is important to take into account the following processing nuances:
Another tree can be strengthened with your own hands using birch sap, saline, drying oil or liquid glass.
