What can be cooked from squid: quick and tasty

Today drying oil is one of the main components of various putties and oil-based paints. It is also very often used to process any wooden surfaces, for impregnating plastered work areas, and even for sealing small gaps. This universal impregnation agent surprisingly combines many useful functions, which ensures high demand for it.

Oksol drying oil is especially popular, features and specifications which will be discussed below.

What it is?

Oksol varnish is a special impregnating mixture for processing wooden and plastered surfaces before further painting. It protects wood and plaster from decay and damage by bacteria. Can also be used for breeding oil paints... "Oxol" belongs to the category of semi-natural formulations.

More than 55% of the composition of the mass is vegetable oils, another 40% is a solvent, and the remaining 5% are driers, which contribute to thickening and rapid absorption of drying oil into the tree.

The following can be used as solvents by the manufacturer:

• "White Spirit";
• synthetic analogues of vegetable oils;
• pyroplast or pyrene;
• gum turpentine;
• nefras C4.

Driers are auxiliary components that are responsible not only for the good absorption of drying oil, but also for its rapid hardening. Fused, oily or fatty acid resins can be used as them.

The volume and type of solvents and driers used are regulated by special GOSTs developed for each type of additives separately.

Like other finishing and protective solutions, Oksol drying oil has its own unique technical parameters.

Specifications

At present, the production of Oksol drying oil is regulated by such a document as GOST 190 78. This regulatory legal act regulates the composition of these products, the conditions and place of their use, as well as other parameters.

According to him drying oil "Oxol" can be natural, belonging to category B... In this case, in its composition, most of it is taken by natural linseed or hemp oils. The main components of such solutions are vegetable oils. Everyday life allowed to be eaten in pure form.

Combined "Oksol" belongs to the PV category, most of its composition is corn or rapeseed oil. But the main difference is that they belong to semi-natural ingredients, they include synthetic additives in advance, that is, such oils are technical and cannot be used in food.

In addition, the GUEST states that this drying oil must have the following qualities:

• complete transparency;
• pronounced smell;
• maximum drying time - 3 hours;
• acidity - 6-8 units;
• viscosity - 18-25 units;
• the flash point in a closed crucible is exactly 32 degrees.

"Oxol" of group PV is suitable for indoor use only, and the product of category B can be used both indoors and outdoors.

The sale and transportation of drying oil can be carried out in containers made of special plastic or iron barrels made of acceptable metal alloys. If the product does not match at least one technological condition, it should not be allowed for sale, since it does not meet the requirements of GOST.

Consumption

The consumption of this product is calculated based on the amount of substance consumed per 1 m2 of surface.

The approximate consumption is:

• drying oils of category B - 80-120 g / m2;
• "Oksoli" PV - 100-150 g / m2.

These consumption rates are approximate and may vary depending on the type of surface to be treated and the number of layers applied to it. For each subsequent layer, a smaller amount of the composition is consumed.

It is also important to know that the consumption will increase when impregnating plastered or too old timber structures... The volume of consumption of Oksol varnish is also influenced by the method of its application - when using a brush, it is less than when using a roller.

Scope of application

Today drying oil "Oksol" is used in a number of cases:

• It can be used to paint wooden structures inside and outside facades.... In these cases, the solution prolongs the life of the wood, reduces the level of negative effects of temperature changes and pathogenic fungi on it.
• For processing plastered facades before their further painting... In this case, Oksol helps to reduce paint consumption during final finishing, and also partially smoothes work surface and protects her.
• For diluting oil-based paints... This allows you to increase the volume of paint, dilute the thickened substance without violating its technical qualities, and also use the resulting mixture as an impregnation and final solution at the same time.

It turns out that it is allowed to use Oksol drying oil for processing wooden structures indoors and outdoors, as well as for impregnating plastered walls. At the same time, it is categorically impossible to use this solution for staining and impregnating floors.

Manufacturers

Drying oil "Oksol" is in demand and popular finishing material, therefore, today many brands are engaged in its production:

• Tex company releases this product for sale in a completely ready-to-use form. Drying oil is sold in containers weighing from 0.4 to 8 kg in one container. The composition dries quickly, significantly reduces paint consumption and performs the work of the primer at the same time.
• LLC "Yamshchik" carries out the manufacture and direct sale of this impregnating composition, belonging to the category of PV. It is sold in containers with a capacity of 0.8 to 20 kg. These products fully comply with the requirements of SanPiN and are manufactured in strict accordance with GOST.
• Drying oil of Isolate brand considered one of the highest quality. Manufactured in accordance with accepted standards. It is sold in containers with a capacity of 0.5 to 200 liters. The disadvantage of this company is that it produces drying oil of this type only to order and in bulk.

• LLC "VESTA-COLOR" manufactures and sells drying oil of this type wholesale and retail. The goods of this brand are of high quality, affordable cost and high technical characteristics.
• PO "KHIMTEK" has been manufacturing and selling these products for over 20 years highest quality...

Sold in containers of various kinds, which allows each customer to purchase the most suitable packaging.

Linseed oil "Oksol" produced by all these brands in practice has proven its high efficiency and excellent quality, therefore, when purchasing such a product, it is recommended to first of all pay attention to these manufacturers.

Features and rules of application

This composition belongs to the category of fast-drying and fast-hardening substances, therefore, it requires adherence to certain recommendations when working with it:

• the mixture is sold in a ready-to-use form, but before its direct use, it is recommended to thoroughly mix the drying oil so that the active active ingredients are evenly distributed throughout the liquid;
• impregnation can be carried out only on dry, clean and previously degreased surfaces;
• it is necessary to apply the solution in a rather thin layer, using a wide brush or a small roller for this;
• the air temperature during work should not be below 15 and above 20 degrees, and the humidity should not be more than 75%;
• each layer of drying oil dries for about a day, so each new application should be carried out no later than 24 hours later;
• it is very important at the end of the work to remove from the room all tools and materials that have come into contact with drying oil;

• unspent mixture can be stored for no more than 12 months in a hermetically sealed container;
• during work it is recommended to use a respirator or a protective mask and rubber gloves;
• if the composition gets on the skin or eyes, it must be thoroughly washed off with plenty of water;
• when carrying out work in a closed room, it is imperative to provide fresh air to it;
• drying oil "Oksol" is highly flammable, so it should be used as far as possible from open sources of fire;
• when purchasing this product, it is imperative to demand from the seller certificates of quality, safety and compliance with the requirements of GOST;
• this composition is allowed to be used for sealing small gaps. For this drying oil is mixed with sawdust in equal proportions and applied to the surface to be treated with a spatula.

In construction and everyday life, wood is very often used, but Oksol drying oil will help protect it from the destructive effects of insects and time. Let's get acquainted with the features of this composition, its characteristics and, of course, dwell on the practical part.

Purpose and principle of action of drying oil

The principle of operation is that most oils, when in contact with oxygen, heat and light, thicken very intensively, and a thin layer completely solidifies. This is due to fatty acid glycerides, because their amount and the degree of iodine number (an indicator of the number of double bonds in the carbon chain) are directly proportional to the speed of solidification of the product. The most effective are flax and hemp compositions of Oksol drying oil (GOST 190–78), since the oils of these plants contain 80% and 70% of linoleic and linolenic acid glycerides, respectively, and the iodine number exceeds 150.

It should be noted that in its natural form, any vegetable oil hardens for a long time, and in order to accelerate this property, it is subjected to heat treatment. When heated, substances that inhibit hardening decompose, and salts provoke rapid oxidation. In addition, special compounds are introduced that contribute to its rapid drying (desiccants). As a result, the film applied to the surface turns into a solid state in a time from 6 to 36 hours.

Types of drying oils and their features

There are several varieties. Natural 97% consists of plant oils (sunflower or flax), the rest is a drier. Their main purpose is to dilute paints and treat wooden surfaces indoors. Such drying oils are divided into oxidized and polymerized. The latter have a darker color, and products processed with it age faster.

The characteristics of Oksol varnish (GOST 190–78) practically do not differ from natural. It is used for indoor and outdoor work. But the composition also includes a solvent, which gives a pungent smell. Also, this type is cheaper than the previous one. Oksol linseed oil is produced in two grades - "V" and "PV". The first ones are created on the basis of flax or hemp oils. To create the latter, petroleum resins and other technical oils are used. Therefore, when working with drying oil, especially the "PV" brand, you should be extremely careful, wear respirators and protective gloves.

Often Oksol is marked "combined", "compositional" or "semi-natural", which once again proves its origin. But sometimes it makes a fundamental difference for those who care about the composition. Combined Oksol received rapeseed oil as a natural component, while sunflower oil was mainly used for production. But the situation was complicated by the fact that the new component belongs to the non-drying class. Then it was pre-oxidized, and as a result, the combined Oksol received the same characteristics as the original version of the composition.

In the broadest sense of the word, combined drying oil is obtained by mixing oils of several plants or those that have undergone different processing, the addition of synthetic substances and a solvent is also allowed... The use of this option is more common in the preparation of paints. Several brands of drying oil are produced. In the designation, the first is the letter "K", followed by a number. If an even number is indicated in the marking, then the mixture is used for interior work, and an odd number for painting exterior objects.

The last type is synthetic compounds. The basis for paints is alkyd drying oil, its cost is much lower than oil, which is an undoubted advantage. Another type is compositional compositions. Their quality is not high enough, and due to increased toxicity, the use is limited only to outdoor work. When choosing synthetic drying oils, you should be extremely careful, since if there is even a small sediment of natural oils in them, then the layer after coloring may not dry out for a very long time. The presence of such inclusions can be determined visually. This mixture has a reddish tint and black sediment.

Technical characteristics - we study GOST

The Oksol varnish (GOST 190–78) has the following properties. Due to the solvent, it has a pungent odor that does not disappear immediately. Complete drying time is no more than a day. In addition, Oksol drying oil is highly flammable and toxic, therefore, when working with it, you should adhere to all safety rules.

According to GOST 190–78, marking is carried out depending on the composition, for example, with excellent properties of drying oil "B" is made only from hemp and linseed oil. It can be used both for dilution and for making oil paints. It is also permissible to carry out external and internal painting work. The drying oil "PV" has a similar purpose, created on the basis of other technical vegetable oils (sunflower, grape, soybean, corn, etc.), but its use is limited only to indoor work.

Both types of Oksoli cannot be used for painting floors.

The technical characteristics of Oksol drying oil are specified in GOST 190–78, but we will still dwell on them in more detail. The acid number for type "B" is not more than 6 mg KOH / g, and for "PV" - 8 mg KOH / g. An exception is drying oil based on sunflower oil, in this case this figure can reach 10. It is unacceptable that the sludge exceeds 1%, the transparency must be complete. The mass fraction of non-volatile substances ranges from 54.5 to 55.5%, regardless of the brand. The flash point in a closed crucible is above 32 ° C.

Oksol drying oil is stored mainly in a metal container, but it is strictly forbidden to open it with tools that give a spark. During transportation, it is necessary to use the transport markings, namely the “Keep away from heating” sign. In more detail, all the characteristics of the composition, as well as safety requirements, test methods and acceptance rules are described in GOST 190–78.

Wisdom of coloring products by Oksolya

Now we will consider the features of the use of Oksol drying oil. In general, there is no great difficulty in this, but we want to highlight some of the nuances, so we will analyze the order of work.

How to paint products with Oksol linseed oil - a step-by-step scheme

Step 1: preparatory phase

Due to the strong odor and toxic emissions, special attention should be paid to safety. All work is carried out in overalls, the respiratory organs also need special protection, so a respirator should be prepared in advance, and rubber gloves are put on hands. If the composition gets on the skin, then it is necessary to immediately wipe it off with a cloth soaked in vegetable oil, and wash the damaged area well with warm water and soap. Avoid getting drying oil into the organs of vision. In addition, the presence of open flames in the premises where the work is carried out is prohibited. And all sources of lighting and electrical equipment must be reliably protected from explosion. And be sure to provide good ventilation.

Any kind of work on interior decoration premises that are associated with painting wooden surfaces with oil paints cannot do without the use of drying oil. Even despite the recent emergence of new, more improved formulations that perform the same tasks. What is the drying oil? What is it for and how to use it correctly? - these are the questions, the answers to which will help you get a perfectly painted surface.

Types of drying oil

At the moment, it is customary for experts to distinguish three types of drying oil: natural drying oil, Oksol drying oil and composite drying oil.

Natural drying oil

Natural drying oil, the quality of which is strictly regulated by GOST 7931-76, consists of 97% of vegetable oil natural origin (linseed or sunflower), specially heat treated, and 3% from desiccant.

1. This varnish reliably protects the wood, however, it can only be used indoors.
2. In addition, natural linseed oil has a fairly high cost by today's standards.

Drying oil "Oksol"

Oksol drying oil, the qualitative composition of which must comply with GOST 190-78, is a substance that has a slight odor and consists of 55% vegetable oil (linseed or sunflower oil), 49% white spirit and 5% desiccant.

1. "Oksol", along with natural drying oil, perfectly copes with its main task, namely, it protects wooden surfaces, forming a dense water-resistant film that does not turn black for a long time.
2. At the same time, drying oil "Oksol" is much cheaper than natural drying oil and, unlike the latter, it can be used even for processing any surfaces outside the building.
3. The best is the Oksol drying oil, which contains linseed oil, so it costs a little more than the one produced on the basis of sunflower oil.

Composite drying oil

Composite drying oil is the cheapest drying oil with a characteristic pungent odor. It does not have a GOST number, therefore the composition of such a substance is not regulated at the legislative level, and the production is carried out exclusively according to technical conditions.

1. Composite drying oils, as a rule, contain various chemical components, in particular, harmful and toxic for human body petrochemical products (for example, petroleum resins).
2. Therefore, such formulations are strictly prohibited to be used indoors.
3. The smell of composite drying oil is retained for a long time, even with good ventilation in the room. it is the cheapest linseed oil with a characteristic pungent odor.

Features of the application of drying oil "Oksol"

Oksol varnish is a fast-drying substance that has increased hardness and forms a glossy coating on the surface of the material treated with it. It penetrates well into the pores of the tree, thereby emphasizing its structure.

• The drying oil "Oksol" is on sale in containers of various capacities, completely ready to use.
• It is necessary to apply such a substance on a dry surface, which, if necessary, is sanded in advance and thoroughly cleaned of dust or grease. Only after that do they switch to drying oil.
• First, the composition is well mixed, if the drying oil thickened during storage, it can be diluted with white spirit, nefras, and also, if desired, with a solvent for varnishes and paints (oil and enamels).
• Linseed oil is applied in a thin layer with a brush or a special roller. At the same time, all work should be carried out in a room that is well ventilated with an air temperature of at least 15 degrees Celsius and a relative humidity of 80%.

• Drying time for Oksol varnish is about 24 hours, so the interval between each subsequent layer should be about a day.
• The rest of the unused drying oil can be stored for a year in a tightly closed container. A dark, dry place inaccessible to children is suitable for this.
• To protect your hands during the drying process, it is recommended to use rubber gloves. It is also important not to let drying oil get into your eyes. If drying oil got on open areas bodies, then they are cleaned with a rag or rag dipped in vegetable oil. Then everything is thoroughly washed with warm soapy water.
• With the help of Oksol oil varnish, you can also putty small cracks by mixing it with wood sawdust until a thick homogeneous mixture is obtained.
• All work to avoid fire hazards must be carried out away from sources of open fire.
