The requirement is very important when a solvent used for chemical cleaning can evaporate at a fairly low temperature and easily remove from clothing that has undergone chemical cleaning.
Due to the fact that Walklin has a low boiling point (47.6 ° C) and a low specific heat capacity (0.218 calg), it is very volatile, which provides drying of clothing after cleaning at room temperature or temperature, slightly different from room. Thus, fibers that are very sensitive to an increase in temperature (acrylic fibers – Orlon, acrylan, as well as modacrylic fiber Dainel), do not lose their qualities with chemical cleaning.
Surface tension. A very important indicator of the quality of the solvent is the value of its surface tension, it largely determines the ability of the solvent to moisten the surface, penetrate the smallest pores of the stain of the dirt to dissolve its binding substances, as a result of which insoluble dirt is carried together with the solvent.
As you can see, the shaft differs from other solvents with low surface tension.
The toxicity of Valklin was determined by the American conference on labor hygiene issues, which issued a leadership that determines the extreme limits of the concentration of solvent vapor in the air, providing, as they believe, the ability to work in this atmosphere without any harmful effects on health. These limits are shown in the table, and the unit of measurement is the number of particles of solvent vapors per million air particles.
These limits show that Walklin, from the point of view of the safety of workers involved in chemical cleaning, is extremely acceptable.
