In our warehouse on Kolejowa Street in Katowice we have stockpiles of chemicals used for cleaning, degreasing, cleaning both solvent and water-soluble concentrates. . Preparations are so chosen to satisfy the expectations of our customers, cleaning soiled and greasy metal surfaces, corrosion protection, passivation of surfaces. Preparations comply with the standards and requirements of human health and the environment protection
The solvent is a liquid capable of forming a solution when mixed with solid, liquid or gas
Most solvents are compounds with low viscosity and relatively low boiling point. Low viscosity means that they can quite easily penetrate the dissolved substance and the low boiling point allows the distillation and evaporation.The basic division of solvents due to their physico-chemical properties. According to the physical properties can be divided into two main groups:
- nonpolar (apolarne) - with small or zero dipole moment
- polar - consisting of compounds with significant dipole moment.
By contrast, due to the chemical properties are divided into:
- protic - water, alcohols, aldehydes, acids, etc.
- aprotic - polar or nonpolar
In principle, all solvents are polar and aprotic can be both polar and nonpolar. For us, the most important division is the division due to the chemical structure and as solvents because of the chemical structure can be divided into:
- organic - such as liquid alkanes (eg pentane, heptane, hexane, cyklohesan), arena (benzene, toluene, xylene), methylene chloride, chloroform, aliphatic ethers (particularly diethyl ether and THF - pulse), alcohols (methanol, ethanol, propanol, butanol, phenol), esters (eg acetate), ketones (mainly acetone), aldehydes (formaldehyde, acetaldehyde), carboxylic acid or acetic acid, and many others
- norganic: water, sulfuric acid, nitric acid, hydrofluoric acid, liquid ammonia, liquid nitrogen, supercritical carbon dioxide *
* Phase in supercritical fluid arises high temperatures and high pressure, has the ability to dissolve materials, both polar and nonpolar.
General solubility rules allow for the appropriate use of solvents in relation to the dirt, which usually are mixtures of various substances and solids. The general rule is that like dissolves in like. And therefore predict what solvent can dissolve the compound term is relatively straightforward, but must be considered here because there are surprises (for example, salts formed by the action of the acidified emulsion - a mixture of 95% H2O and 5% oil) of the metals will not dissolve in the hydrocarbon-type solvents. |
