Soils encountered

Gleaning Methods. The soils encountered in electroplating processes can be organic, eg, oils, greases, and other cleaning compounds, and... 

Some of these tests are not applicable to soils encountered in that industry. 

Another example of silicon compound use is in the very specialized area of glass-topped stove cleaner/conditioners [57], These can be thought of as a special kind of cream cleanser with an added benefit. The strength of an abrasive cleaner is needed to remove the baked-on soil encountered on a stove top, and as long as the abrasive is less than Mohs hardness 6 the glass top will not be scratched.

First this discussion will tnm to the simplest of the specialty cleaners, those based on very high pH the oven and drain cleaners. Both are usually based on a high concentration of an alkaline ingredient such as sodium hydroxide. In both cases, the alkalinity of the formula is key to its ability to clean the soils encountered in these problems. The choice of snrfactant is somewhat limited, as the surfactant needs to be stable at pHs of 11-14, bnt there is still reasonable choice. The main function of the surfactant in these products relates primarily to their foaming. 

In order to determine the expected water level in the completed dam, seepage analysis is conducted using the data from soils encountered at the site, as well as soils to he part of the tailings or construction. Seepage from the blanket drain or cycloned sands should be collected in a trench and sent to a sump where it can be measured. 

The distribution of potential along the survey of earth above the pipeline indicates the location of corroding areas. Different types of soil encountered by the pipe affect the potential of the pipe. The changes in soil resistivity also induce potential differences. The surface potential surveys are made to determine the anodic and cathodic areas on the pipe. The structure-to-soU potentials do not give a quahtative measurement of corrosion, however, they are very useful in prediction of corrosion when used in conjunction with other data,... 

Cap grouting. Constructing a concrete cap over the potential sinkhole by injecting a thick, mortar-like grout. Often carried out in combination with compaction grouting of the soils encountered above the cap. 

The soils encountered on textile fabric may be classified according to their solubilities which ultimately determine their best way of removal. 

Soil retardants are used to reduce soiling of textiles that cannot be laundered, such as upholstery fabrics and carpets. The soils encountered are usually composite soils, containing particulate matter and various amounts of liquid components, such as water or oil. The soils can therefore be fluids or particulate solids. 

In general, there are two types of soil encountered in detergency simations liquid, oily substances, and solid particulate material. Many stains on textiles such as blood, wine, mustard, catsup, and the like involve proteins, carbohydrates, and relatively high-molecular-weight pigmentlike materials that pose special problems in terms of the interfacial interactions involved. The interactions of each class of soil or stain with the solid substrate can be quite complex, and the mechanisms of soil removal may be correspondingly complex.
