描述:
Petroleum solvents (or nefras) are solvents from organic materials obtained by distillation of petroleum. They include a complex mixture of hydrocarbons derived from petroleum distillation fractions that have been further refined by one or more processes. Known types of such organic solvents include nefras "Galosha", gasoline, white spirit, kerosene, etc.
概观:

These fluids are used as industrial cleaners, dry cleaners, paint thinners, copier toners, adhesives, and as a general grease remover.

Nefras are used to clean parts in production, as they quickly dissolve oil contaminants, grease, soot and soot.

Such solvents easily remove all oil pollution, oils and fats, as well as other organic compounds. The action of the solvent increases with an increase in the proportion of aromatic hydrocarbons in it. Note that such liquids do not mix well with water.

You can buy nefras in Yekaterinburg at the Etilamine-Ek company .

Labeling of petroleum solvents

Organic solvents are marked according to a single standard. After the general name of the substance, its group and subgroup are noted, and then the values \u200b\u200bof the temperature (in ° C) of the beginning and end of the distillation are given. For example, Nefras-C2 80/120 , Nefras-A 120/150 .

According to their composition, petroleum organic solvents are divided depending on the content of which substance exceeds 50%:

  • P - paraffin;
  • I - isoparaffin;
  • H - naphthenic;
  • A - aromatic;
  • C - mixed (the content of each of the hydrocarbon groups does not exceed 50%).

In addition, liquids are divided into 6 subgroups (0 - 5), which differ in the proportion of aromatic hydrocarbons in the composition:

  • less than 0.1%;
  • 0.1-0.5%;
  • 0.5-2.5%;
  • 2.5-5.0%;
  • 5-25%;
  • 25-50%.

All of these petroleum solvents can be purchased from Ethylamine-Ek in Yekaterinburg. All products are manufactured in accordance with TU 38.401-67-108-92 .

Hazards and Precautions When Using Petroleum Solvents

Solvents are flammable, can be very volatile and can explode or catch fire if not properly stored or handled. In particular, welding near solvents can present a fire and explosion hazard.

Proper use of ventilation and safe storage of solvent containers is essential to prevent these hazards.

However, although petroleum organic solvents are of low toxicity (compared to other types), they have adverse health effects when accumulated for a long time or inhaled in large quantities. High concentrations of certain solvents in the air can cause unconsciousness and death. Exposure to lower concentrations of solvents may result in short-term effects including eye, lung and skin irritation, headache, nausea, dizziness or vomiting. Chronic exposure to these substances may be associated with an increased risk of lung cancer, dermatitis, and thyroid problems. Some of these effects may also increase the risk of an accident. Repeated exposure to certain solvents can have long-term health effects.

Workers working with flammable solvents should be provided with splash goggles or protective shields. In addition, adequate ventilation must be provided in workplaces to remove airborne solvents. This can be either exhaust ventilation at workplaces, or simply ensuring the supply of fresh air to the work area.

Among the main advantages of petroleum solvents:

  • Dissolution of most organic contaminants.
  • Accelerated evaporation.
  • The ability to quickly clean the surfaces of metal parts from contamination.
  • Corrosion compensation due to the presence of sulfur compounds in the liquid.
