Industrial Parts Washers Terms
–
A substance for aggressive cleaning, typically sand, garnet, steel or
aluminum oxide.
– Any aqueous mixture having
a pH less than seven on a one to 14 scale. Any acidic solution with a
pH lower than three is considered strongly acidic.
– Cleaning utilizing
acids combined with surfactants to removing rust, metal or scale. Acids
with a pH lower than six do not work as degreasers.
– The use of mineral
acid to remove scale and rust from metal.
– A device that provides
a pressurized “curtain” of air for cleansing, cooling or drying.
– An aqueous
cleaning process done with a greater than 7 pH level utilizing phosphates,
silicates or other alkaline salts combined with surfactants in water.
– Materials that
microbial activity can naturally reduce from their original state into
simple chemical compounds.
– Nature’s
way of cleaning using microorganisms (bacteria, enzymes, fungi) to break
down the organic compounds in waste or pollutants.
– The use of pressurized
air to clean or remove excess water.
– Solutions of salt
in aqueous cleaning systems that maintain a preferred pH level. Aqueous
cleaners use buffers since the precipitation and solubility of metals
affect the pH level.
– These additives enhance
the effectiveness of detergents by sequestering metals like magnesium
and calcium. A problem is that a lot of builders contribute to environmental
damage, with substances such as phosphates.
– A rinsing process
that involves transferring product through a sequence of tanks, in which
the rinse water in the last rinse tank runs over to previous tanks in
the sequence (a countercurrent flow). This permits the product to be subjected
to progressively pure water.
– A drying
process using a basket quickly spinning for separation of excess oils,
water or other substances from parts. A turbine fan installed underneath
the basket pulling the air through improves the process.
– A parts
cleaning system in which the water is purified and then re-circulated
through the system after purification treatment; in aqueous cleaning systems,
it goes back into the wash and rinse tanks and is a cost saving measure.
Membrane, reverse osmosis and ion exchange filtration are typical techniques
to purify the water.
– The degree to
which an aqueous mixture can conduct electricity and an indication of
the purity of the water. The level of conductivity is reciprocal to the
level of resistance (e.g. the lower the conductivity, the higher the resistance
and the greater the water purity).
– The use
of companies through contracts that specialize in cleaning industrial
parts and components and provide services to a wide range of industries
and are comprehensive in their operations - from simple aqueous and solvent
cleaning to analytical testing.
– A chamber
that evaporates water from cleaned components through heated air.
– A substance
used to slow the chemical reaction that causes rust.
– A cleaning
process that utilizes at least two solvents to achieve the cleaning and
rinsing. The action of cleaning results from the combination of the characteristics
of each solvent involved, which are selected for the greatest optimization
of the system in relation to the particular contaminants involved.
– A solvent or combined
material for removing grease, oils, or fat from substrates.
– Water
that has enhanced purity resulting from the elimination of ionic species.
– A solution that
is a combination of surfactants comprised of both hydrophobic and hydrophilic
material for making grease and oil water soluble. Cleaning is actually
done when the soil attaches to the hydrophobic group and when the detergent
soil mixture is emulsified in the water; the detergent’s cleaning
capabilities are increased through the addition of builders or other additives.
– Solvent cleaners
that have an insoluble aqueous level that is typically utilized along
with paint strippers; when combined with denser chlorinated solvents,
the water becomes the upper level.
– This material
enhances the stability of particles emulsified in a liquid-solid or liquid-liquid
suspension and is also known as an emulsifying agent.
– The creation
of micelles in a cleaning procedure resulting from the dispersal of liquid
or solid globules or fine particles into a bulk liquid.
– A device that circulates
large amounts of solution in the tanks.
– Cleaning the cleansing
solution and trapping the contaminants so the solution can be used for
a longer period and so the components being cleansed don’t retain
any of the soil or particulates.
– A surfactant
molecule that results in the proclivity of the molecule to be water
soluble.
– A water resistant
substance.
– Also known as cold
cleaning, it is the cleaning that takes place in a tank, usually of a
rectangular shape, using an aqueous solution. The cleaning is done primarily
through soaking in a water chemical solution.
– Additives that
impede harmful chemical reactions between an aqueous cleaner and a substrate.
Inhibitors typically retard the corrosion process of non-ferrous substrates
in high pH or iron.
– The use
of mechanical energy via a circulation pump to circulate cleaning solution,
effective for components with flat surfaces or those that have a simple
configuration.
– An amalgamation of
solutions with both hydrophilic and hydrophobic properties that trap non-water
soluble oils. Dispersal of detergents and other surfactants results in
micelles.
– The use of nozzles
to aim air at specific areas of a component for water removal.
– A process in which a cleansed component with intricate passages
is subject to a clamping procedure and forced air enters the passages
and dries the part.
– To flood the washed
components with clean water or a rinse solution.
– A binding agent
that prevents chemical reactions.
– A substance's capability
to dissolve within another substance, usually a solid in water. Quantification
is in grams per liter, and the general classifications for material solubility
are fully soluble, partially soluble, slightly soluble and insoluble.
– In cleaning systems,
a liquid substance that cleans a part by dissolving the surface contaminants.
– Heavy soils that sink
to the bottom of an aqueous solution.
– Allowing components
to rest in cleaning solution so chemicals can “lift” the dirt.
– In reference to
industrial part washing, any item with contaminant or soil on it that
is being exposed to a cleaning process.
– An abbreviation
of “surface active agent,” it is a common additive for lowering
the surface tension between an aqueous cleaning solution and hydrophobic
soils in order to loosen the soil or other contaminants. Detergents are
principally composed of surfactants.
– Organic compounds
that occur naturally and are usually found in essential oils. Utilized
as cleaning agents in semi-aqueous cleaners, they come from natural sources
like citrus fruit or pine trees.
– A process that
is particularly useful for evaporation of water at a relatively cool temperature.
A vacuum pump is used to dry the product.
– An
up-and-down movement of components to allow cleaning solution to remove
contaminants; vertical part agitation is effective for parts with cavities.
– Soiled water from
the cleansing process.
