In addition, DY377 metal extractant also has some other physical and chemical properties, such as specific gravity, flash point, content, dynamic viscosity, extraction phase separation time, and back extraction phase separation time. Below, we will explain them separately:
1. Specific gravity (25 ℃): 0.90-0.92 Specific gravity refers to the ratio of the weight of a substance per unit volume to the weight of water at the same temperature and pressure. It is an important indicator for evaluating the density of a substance. The specific gravity of DY377 metal extractant ranges from 0.90 to 0.92, indicating its low density and ease of operation and treatment.
2. Flash point (closed cup):>70 ℃ Flash point refers to the minimum temperature required for a substance to burn under certain conditions, that is, the spontaneous ignition point of the substance. DY377 metal extractant has a high flash point, reaching over 70 ℃, making it relatively safe and less prone to fire.
3. Content (50% m/m): ≥ 47% Content refers to the mass fraction of the active ingredients contained in DY377 metal extractant, which is an important indicator for evaluating the purity and efficacy of the drug. At a content of 50% m/m, DY377 metal extractant can exert good extraction performance and effect.
4. Dynamic viscosity (25 ℃): ≤ 100CP Dynamic viscosity refers to the degree to which a fluid is difficult to flow in a stationary state, and is an important indicator for evaluating fluid viscosity. DY377 metal extractant has a low dynamic viscosity and is less prone to adhesion and sedimentation, which helps to improve extraction efficiency and operational performance.
5. Extraction phase separation time: ≤ 150s Extraction phase separation time refers to the time when DY377 metal extractant separates two liquid phases after mixing with metal solution. It is an important indicator for evaluating the extraction speed and separation effect of DY377 metal extractant. The extraction phase separation time of DY377 metal extractant is relatively short, and two liquid phases can be separated within 150 seconds.
6. Reverse extraction phase separation time: ≤ 100s. Reverse extraction phase separation time refers to the time taken to reverse extract metals from DY377 metal extractant after mixing the solution of metals extracted by DY377 metal extractant with reducing agent. It is an important indicator for evaluating the reverse extraction effect and speed of DY377 metal extractant. The back extraction phase separation time of DY377 metal extractant is relatively short, and it only takes 100s to achieve the back extraction separation of metals.
