scopes, unlike white spirit + Video

scopes, unlike white spirit + Video Surely every person in his entire life at least once, but came across paints and varnishes. At the same time, you periodically have to degrease, dilute, clean something.

A quality solvent can handle all of these tasks. There are many of them on the modern market, there are popular products, there are less well-known ones, but among such an abundance, a solvent solvent differs.

The substance is very effective and popular.

An important recommendation when working with it is to be careful.

What is a solvent?

Solvent belongs to the group of organic solvents. It is a liquid that can instantly dissolve paints and varnishes. The consistency is similar to light carbohydrates, which makes the material volatile and flammable. The solvent appears as a result of the processing of coal and oil.

The product corresponds to GOST (10214-78, 1928-79) and is divided into two types:

  1. As part of specially processed stone and coal, giving a substance called coal solvent. It is able to completely burn out paints and varnishes without a trace and odor.
  2. Petroleum solvent is an effective means for removing paints and varnishes, dissolving bitumen, rubber, oligomer, petroleum resins. It is used for diluting paints, washing liquids, enamels. Often found in the automotive industry.

To make such a tool, they resort to pyrolysis of oil fractions. The solvent contains few substances. The base is a hydrocarbon that occupies 50% of the solvent structure.

The rest are:

  • scopes, unlike white spirit + Video - naphthenes;
  • - paraffins;
  • - hydrocarbons with a cyclic form.

Such a solvent is divided into 2 groups - superior and first grade.

Their difference is manifested in the fractional composition, the amount of sulfur and the flash point.

Manufacturers of petroleum solvent - Shell, Virage, Lukoil-Permnefteorgsintez, etc. The goods are delivered in cans, barrels, cans and other containers.

Characteristics of the solvent

If we consider the coal-tar solvent from several positions, then the following characteristics can be distinguished:

  • it used for removing paints and varnishes, diluting paints, washes, enamels;
  • solvent can be from colorless to slightly yellow, by which an experienced specialist can recognize the composition and brand;
  • depending on the brand of the product , the solvent has a different density;
  • aromatic hydrocarbons in the composition are extracted by processing and purifying fractional crude benzene and pyrolysis resin;
  • xylene is an indicator of the volatility of the solvent. However, it should be within 1.

    8-2%.There is little phenol - in grade A only 0.01%, B - 0.02%, C - 0.1%;

  • is sold in barrels of 220 liters;
  • is stored for 1 year after manufacture;
  • water and various impurities should not be present in a high-quality solvent;
  • such an indicator as sulfur, grade A contains 0.

    1%, B - 0.15%, and C - 0.3%;

  • reaction to water extract equals 0;
  • after drying gives the paint a shine.

Characteristics of petroleum solvent:

  • scopes, unlike white spirit + Video - dissolves oils, bituminous derivatives, petroleum resins and polyesteramides;
  • - the composition boils at above 150 degrees;
  • - the technical characteristics are as follows: the sulfur content does not exceed 0.012%, a small proportion is included in aromatic hydrocarbons naphthene and paraffin;
  • - density should not fall less than 0.

    861 g per cubic meter at 20 degrees Celsius, volatility not more than 0.021;

  • - reaction of water extract - neutral;
  • - sold in containers of 9 liters (8 kg) and in cans of 218 liters (172 kg);
  • - shelf life - 1 year from the date of manufacture;
  • - price for 0.5 liters from 60 rubles.

Looking at such characteristics, there is no doubt that the solvent is a toxic but effective substance. This solvent is dangerous, so the concentration of vapors in the air should be no more than 50 milligrams per cubic meter.

Otherwise, the substance can damage the insides of a person, cause loss of consciousness, a deteriorated state of the immune system.

Differences between Solvent and White

When the consumer's task is to create a protective layer on the surface, then it is better to use White Spirit. He will cope with this task many times better, despite the instant of Solvent. Both products are obtained from petroleum distillation. The difference is in the boiling point.

The boiling point is the moment when the oil vaporisates into a solvent. This is the difference between white spirit and Solvent. Spirit is obtained at a low temperature, in contrast to class II solvents.

Solvent passes from a liquid state to a gaseous state even at low temperatures, therefore it dries faster, which is its main advantage over similar paints and varnishes. The glossy surface is due to the small presence of oily substances.

But White dries much longer, as it boils at 200 degrees Celsius. It contains more oil components, which gives the treated surface a matte finish. In this connection, it is advisable to use such a solvent on metal products.

To visually compare the substances, you can take a sheet of paper and drop both solvents on it. It will immediately become noticeable which one has a quick drying and gloss formation ability and vice versa.

White spirit is translated from English as "white spirit" in its composition has a lot of detergents, and not a very high concentration, although in functionality it is similar to Solvent, which is practical to use for cleaning some parts of the car, rinsing and working with the fuel part of the unit.

A thinner is also added to the paint in order to make it less viscous in consistency.

When choosing between Solvent and White Spirit, you should decide what task you want to complete. If you need quick drying and a glossy surface, then there is nothing to think about - Solvent. In the case where the goal is to create a protective layer and opacity, then White.

Areas of use

This solvent is universal and can be used for:

  • working with varnish on any surface;
  • using paint, enamel;
  • working with materials such as rubber and bitumen (oil solvent does an excellent job). You need to be very careful and adhere to safety measures;
  • the use of polyesters, oligomers, oils of various consistencies, phenols, polyacrylates, melaminoalkides, alkyd-urethanes, alkyd-styrenes, etc.

Both type of Solvent are used not only when working with paints and varnishes, but also in construction, the auto industry, when it is necessary to dilute alkyds, enamels and other materials to a normal state.

The range of solvent applications is wide. The main purpose is to dissolve:

  • enamels;
  • paints;
  • oils;
  • bitumen;
  • polyesters;
  • varnish ;
  • rubber.

The big advantage of Solvent is its instant action. No other similar product can boast such a result. The solvent destroys the paint and varnish structure and dries up in a matter of seconds.

In the construction industry, a solvent is needed at the final stage of work when painting premises. The product Nefras A130 / 150 is popular, it is also an oil solvent.

In the automotive industry, coal-tar solvent is used to clean various mechanisms such as injectors.

Thanks to its amazing instant drying property, this product is indispensable in the printing industry. It is a popular substance on vinyl films, banners, outdoor posters, stencils, and inkjet printing. The solvent allows the applied pattern to stick to the surface very quickly, and by applying drying almost instantly.

As for paints, when they contain Solvent, they are toxic and can accumulate in the human body, which, if used for a long time, causes health problems.

Such paints are easily recognizable by their strong odor.

The fact that this coal-type solvent is contained in means of controlling various insects also speaks of toxicity.

Safety rules

Only compliance with safety measures can protect the human body from the toxicity of the drug.The most dangerous is the release of vapors into the air, from where there is an effect on the central nervous system of a person. The consequences are irreparable - narcotic effects, problems with the respiratory tract, etc.

If the solvent comes into contact with human skin, then severe irritation or even a burn is formed. In this situation, immediately rinse the skin area with warm soapy water.

To prevent the negative influence of Solvent, it is enough to comply with the safety requirements:

  • exclude direct contact with the human body;
  • scopes, unlike white spirit + Video In the event of a liquid spill, collect it using sand, sawdust and appropriate protective clothing;
  • Solvent in waste water;
  • The solvent ignites at a temperature of 22 degrees with the possibility of self-ignition. It is necessary to extinguish the flame with foam, carbon dioxide, sand, but not water;
  • when working with a solvent, you need to use overalls, a gas mask, gloves, protective pastes;
  • there must be powerful ventilation where substance is used;
  • the place where Solvent is stored must be isolated. It is allowed to enter such a room only in overalls, so as not to earn health problems.

Summing up, we can say with confidence that the solvent is highly flammable, with a pungent odor and increased toxicity. It is effective and can evaporate even at low temperatures, due to which it dries quickly. It is in demand not only as a quick-drying substance, but also as a product that leaves a glossy shine on the surface.
