Emulsification time (pt)
| Глоссарий терминов по технологиям неразрушающего контроля (NDT) |
- The time allowed for the emulsifier to act on the penetrant before the part is washed, after emulsifier is applied as a separate step.
- Time required for the emulsifying agent to combine with the penetrant. this is critical as insufficient time will result in failure to remove the penetrant and lead to false indications, and too long a time may remove the penetrant from the flaws. emulsification time usually ranges from 30 seconds to 5 minutes.

Emulsifier, английский
- Additive that promotes the formation of a stable mixture, or emulsion, of oil and water. common emulsifiers are: metallic soaps, certain animal and vegetable oils, and various polar compounds.
- A substance which modifies the surface tension of colloidal droplets, keeping them from coalescing and keeping them suspended. emulsion 1. a mixture of liquids insoluble in one another, in which one is suspended in the other in the form of minute globules. 2. a mixture in which solid particles are suspended in a liquid in which they are insoluble, as a mixture of bitumen and water, with uniform dispersion of the bitumen globules. the cementing action needed in roofing and waterproofing takes place as the water evaporates.
- A synonym for mud mixer.
- A machine for mixing water, oil, or resins with a saponifying or other agent to form an emulsion.
- A saponifying or other agent added to water and oil or water and resins, causing them to form an emulsion.
- Эмульгатор
- An additive that promotes the mixing of water and oil to form an intimate mixture of the oil and water (called an emulsion). emulsions generally have a cloudy or milky appearance.
- An additive that promotes the formation of a stable emulsion, usually of oil and water.
- A substance that promotes the formation of a stable emulsion. in industrial maintenance cleaning, emulsifiers are used to modify the surface tension of liquid droplets (dispersed phase) to keep them from coalsecing (agglomerating); the resulting emulsion suspends soil in solution.
- Liquid that mixes with an oily penetrant such that the emulsion can then be washed from the surface with water. see also soak time. emulsifier, hydrophilic: water based liquid that interacts with the penetrant oil in the manner of a detergent, allowing the penetrant to be washed from the surface with water. emulsifier, lipophilic: oil based liquid that mixes with penetrant oil to form an emulsion that can be removed from the surface with water.

Penetration time (pt), английский
The time allowed for the penetrant to enter into surface discontinuities, i.e., the length of time elapsing between the application of the penetrant to the part and removal of the penetrant.
Stereoscopy (rt), английский
The three-dimensional visual effect resulting from binocular vision.
