Properties of wax. The basic indicators characterising properties of wax, its density, fusion and hardening temperature, hardness, viscosity, solubility, mutual relation with metals are.
Wax Density at temperature 15°С-0,956-0,970. It decreases simultaneously with air rise in temperature. On density size it is possible to define various falsifications of natural wax. Fusion temperature (61-65°С), that is transition from a firm condition in liquid, and hardening temperature help to define wax falsification. The the fusion temperature above, the quality of wax is better.
Hardness of wax (no more than 6,5) is of great importance at manufacturing voshchiny which develop only from wax with the raised hardness. For definition of hardness of wax the hardness factor - time of passage of the needle having cross-section section 1,5 мм2, under the influence of cargo in weight of 1 kg on depth of 1 mm serves. Above all the factor of hardness at wax-kapantsa, is less at pressed and the lowest at ekstraktsionnogo than wax.
Solubility of wax. Wax is dissolved only in fat and essence, gasoline, turpentine, serouglerode It can be changed with paraffin, various fats etc. Wax is almost insoluble in spirit and is not dissolved at all in glycerine and water.
