We stop corrosion with Humidur
Glossery
- Abatement
Involves either removal of the painted surface, covering the painted surface with an impermeable surface, or covering surface with heavy-duty coating (encapsulant).
- Abrasion
Mechanical scraping of a rock surface by friction between rocks and moving particles during their transport in wind, glacier, waves, gravity or running water. After friction, the moving particles dislodge loose and weak debris from the side of the rock, these particles can be dissolved in the water source. Abrasion causes erosion.
- Adhesion
The ability of dry paint to attach to and remain fixed on the surface without blistering, flaking, cracking or being removed by tape.
- Amide
A functional group which can act as an epoxy resin curing agent.
- Beam
A beam is a structural element that is capable of withstanding load primarily by resisting bending. The bending force induced into the material of the beam as a result of the external loads, own weight, span and external reactions to these loads is called a bending moment.
- Berth
A berth is a location in a port or harbour used specifically for mooring vessels while not at sea.
- Binder
Solid ingredients in a coating that hold the pigment particles in suspension and attach them to the substrate. Consists of resins (e.g. oils, alkyd, latex). The nature and amount of binder determine many of the paint's performance properties - washability, toughness, adhesion, colour retention, etc..
- Blistering
Formation of dome-shaped projections in paints or varnish films resulting from local loss of adhesion and lifting of the film from the underlying surface.
- Catalyst
Substance whose presence increases the rate of a chemical reaction e.g. acid catalyst added to an epoxy resin system to accelerate drying time.
- Cavitation
The formation of vapour bubbles of a flowing liquid in a region where the pressure of the liquid falls below its vapour pressure. Cavitation is usually divided into two classes of behaviour : inertial (or transient) cavitation, and noninertial cavitation. (See Inertial and noninertial cavitation)
- Coating
A paint, varnish, lacquer or other finish used to create a protective and/or decorative layer. Generally used to refer to paints and coatings applied in an industrial setting as part of the original equipment manufacturer's (OEM) process.
- Cohesion
A bonding together of a single substance to itself. Internal adhesion.
- Corrosion inhibitive
A type of metal paint or primer that prevents rust by preventing moisture from reaching the metal. Zinc phosphate, barium metaborate and strontium chromate (all pigments) are common ingredients in corrosion-inhibitive coatings. These pigments absorb any moisture that enters the paint film.
- Curing
The process whereby a liquid coating becomes a hard film.
- Dolphin
A dolphin is a man-made marine structure that extends above the water level and is not connected to the shore. Dolphins are usually installed to provide a fixed structure when it would be impractical to extend the shore to provide a dry access facility. Dolphins are also used to display regulatory information like speed limits etc., other information like advertising or directions and navigation information.
- Epoxy
Extremely tough and durable synthetic resin used in some coatings. Epoxy coatings are extremely tough, durable and highly resistant to chemicals, abrasion, moisture and alcohol.
- Erosion
The removal of solids (sediment, soil, rock and other particles) in the natural environment. It usually occurs due to transport by wind, water, or ice ; by down-slope creep of soil and other material under the force of gravity ; or by living organisms, such as burrowing animals, in the case of bioerosion. Abrasion causes erosion.
- Fender
In boating, a fender is a bumper used to keep boats from banging into docks or each other. Fenders are nowadays constructed from a rubber or plastic hull filled with air or foam.
- Film build
Amount of thickness produced in an application. Millimeters (mils) of dry film per mils of applied wet film.
- Galvanizing
Process in which a thin coating of zinc is applied to iron or steel to prevent rust.
- Hardener
Curing agent for epoxies or fiberglass.
- Inert
A material that will react chemically with other ingredients.
- Inertial cavitation
The process where a void or bubble in a liquid rapidly collapses, producing a shock wave. Such cavitation often occurs in pumps, propellers, impellers, and in the vascular tissues of plants.
- Marine paint
Coating specially designed for immersion in water and exposure to marine atmosphere.
- Mooring
A vessel is said to be moored when it is fastened to a fixed object such as a bollard, pier, quay or the seabed, or to a floating object such as an anchor buoy.
- Noninertial cavitation
Noninertial cavitation is the process in which a bubble in a fluid is forced to oscillate in size or shape due to some form of energy input, such as an acoustic field. Such cavitation is often employed in ultrasonic cleaning baths and can also be observed in pumps, propellers, etc.
- Nonvolatile
The portion of a coating left after the solvent evaporates ; sometimes called the solids content.
- Penstock
A sluice or gate or intake structure that controls water flow, or an enclosed pipe that delivers water to hydraulic turbines and sewerage systems. It is a term that has been inherited from the technology of wooden watermills.
- Pile
A long column of timber, concrete or steel that is driven into the ground to provide a foundation for a vertical load (a bearing pile) or a group of such columns to resist a horizontal load from earth or water pressure (a sheet pile).
- Piling
A column of wood or steel or concrete that is driven into the ground to provide support for a structure.
- Primer
First complete coat of paint of a painting system applied to a surface. Such paints are designed to provide adequate adhesion to new surfaces or are formulated to meet the special requirements of the surfaces.
- Resin
Synthetic or natural material used as the binder in coatings. Can be translucent or transparent, solid or semi-solid. Examples : acrylic, alkyd, copal ester, epoxy, polyurethane, polyvinyl chloride, silicone.
- Viscosity
The property of a fluid whereby it tends to resist relative motion within itself.
- Volatility
The defining quality of a liquid that evaporates quickly when exposed to air.
- Water turbine
A rotary engine that takes energy from moving water.
