White spirit - a special agent (solvent), which is intended to dilute the various liquid alkyds, certain types of rubber (specifically, it can be and cyclo- butyl) and polybutylmethacrylate.In addition, when the content of the treated substance in the composition of epoxy, the spirit and capable of dissolving it.Why use white spirit, how to apply, what it is transported and the character?Answers to these questions and many more will learn in the course of reading this article.
Scope
often white spirit solvent used to dilute oil paints and receiving the substances listed in the previous paragraph.This tool is used for degreasing surfaces, wash the surface of the products, parts and tools."Do Degreases white spirit well?" - You ask.Such a solvent, thanks to its resistant and aggressive composition, which we will consider later, is able to dissolve even the toughest substances, so when working with him to take care of the additional means of protection.
But back to the application.In addition to degreasing, one of the main features of this type of solvent is a dilution of pastes and conventional oil-based paints, thickened enamel and many other varieties and types of paints.In addition, the white spirit is capable of dissolving a layer of thickened primers, varnishes, bituminous materials and others. And in order that the result of works to justify their expectations, experts recommend washing brushes and rollers in the solvent even before applying them alkyd, oil and pentaphthalic enamels.Most mineral spirits used in industry as a degreasing element used to stain steel metal structures.
But in everyday life it is no less relevant.The farm white spirit is used as a solvent for various bitumen and grease.In addition, it is used for dilution of paints before applying them to the surface, including the automotive and mastics.
White spirit: technical characteristics and composition
This substance is a potent solvent naphtha, which is composed of liquid aromatic and aliphatic hydrocarbons.The production of white spirit achieved by direct distillation of oil, and in some cases, even with special cleaning methods.According to its specifications, the solvent is very flammable.The temperature of the boil-off means is from 155 to 200 degrees Celsius.
In the manufacture of such materials as mineral spirits production following rules:
- share of aromatic hydrocarbons in the volume of the resulting liquid is not more than 16 percent.
- Limiting distillation temperature should not exceed the mark of 160 degrees.
- strictly forbidden to add the substance is any mechanical impurities in the form of water-soluble acids and alkalis.
What distinguishes American mineral spirits on the Russian?
Despite the overall manufacturing technology and composition, as a result of foreign solvents have a lot of differences from domestic.Enumerating something which the foreign funds 'white spirit' characteristics and composition, we note first of all the level of purification from harmful volatile impurities.Here, the main difference lies in the fact that their foreign counterparts in the production through several stages further processing, and therefore have little or no harmful toxic odor.Thus, obtained by the American technology fluid is mostly safe for humans when performing work on the degreased surfaces.The crude white spirit is more potent, toxic and dangerous to human health.And Russian companies in production technology do not use cleaning solvent from harmful substances.Therefore, the domestic product is more dangerous for health.However, it is necessary to emphasize one important advantage - such funds are more bystrodeystvennymi and better clean the surface of the waste materials.This characteristic is achieved just by the presence in the composition of the most harmful substances.In addition, this type of domestic spirit vastly superior in terms of density and flammability foreign liquid.That is why it would be wrong to call the Russian solvent poor quality - in spite of its toxicity, it is much more effective cleaning of varnishes and other substances.
White spirit: composition.The presence of hydrocarbons
also one of the main differences between the substance in question is the level of concentration of aromatic hydrocarbons.As a part of these funds are allowed 16 percent aromatics based on the total amount of spirit.In the foreign substance such analogues are not used in the production.
Adding paints
White spirit mixed with a portion of water-based paints, significantly reduces its consumption, it does not violate the coating quality.However, there is need to focus on what does not lose its properties such paint only if the ratio of solvent additives to the lacquer will be most optimal.Otherwise, the addition of spirits in the paint would be tantamount to the use of water - the result of the work of paint will be minimal.It is also necessary to remember that each manufacturer of a substance indicates its rules and requirements when mixing this product with another.
What's he look?
Based on the article pictures, we can see that this type of spirit is a liquid substance transparent color.The properties of viscosity it resembles motor oil (even sometimes with a yellowish tint).The characteristic smell (reminiscent of kerosene) is clearly felt at a distance of several meters.Pairs of white spirit is very dangerous to the human respiratory tract and can cause severe poisoning.Therefore, use of this solvent is recommended to use a gas mask or respirator, special clothing with protected sleeves and thick rubber gloves.By the way, getting this spirit on the skin can cause severe burns - so much a means of acting.
Marking
In Russia, the substance is released under a single brand: "Nefras-S4-155 / 205".At the same time on each label specifies the name of the Cyrillic alphabet "White spirit".
What is it stored?
this solvent is stored in plastic bottles often.Their amount may be 0.5, 3, 5 and 10 liters.In this last three types of containers are presented in a canister.In an industrial scale for transporting mineral spirits used large 216-liter metal drums.The shelf life of each of these different liquids - from 3 to 10 years.
Flammability
solvent "Nefras-S4-155 / 205" is one of the most flammable substances among all those who are only on the Russian market.To understand how it is active, it is enough to imagine that all the liquid has a flammability classification of certain classes (first, the safest, the fourth - the most vulnerable to fire).So, this type of spirit belongs to the highest - fourth grade.That's why experts is not recommended to use it near flammable items, it is best to do it at a distance of several tens of meters.Thus it should be kept in a dark room.With regard to the storage temperature, everything is much easier - the spirit does not lose its properties at temperatures from -40 to +30 degrees Celsius.
How much is the solvent "white spirit"?
price of the substance depends on the volume of the container into which it is poured.Least cost cheap (35 rubles per unit) will be liquid placed in a 0.5 liter plastic jar.Further, prices are rising in parallel the volume of product sold: 1 liter of funds will have to pay 55 rubles, 5-liter and 10-liter canister is 270 and 530 rubles, respectively.Metal barrel with white spirit in the amount of 216 liters costs about 8-8,5 thousand. Rubles.In some cases, it occurs in a liquid 20-liter cans.They cost about one thousand rubles per unit.
