Optical coating is a process where products are coated with metals to reflect or refract light. Different materials and processes can be used to achieve the desired effect. Optical Coating Labs Inc. was a successful company in the 1970s, but was later bought by JDS Uniphase and dismantled, resulting in job losses. Much of the […]
A casing head is a steel flange fixed to the base of a wellhead, housing blowout preventers and surface equipment for drilling operations. It can also serve as the basis for controls and valves for oil or gas flow to processing facilities. A casing head is part of the wellhead of an oil or gas […]
Powder paint is sprayed onto steel using a special gun, then cured in a kiln to create a durable finish. It’s best for frames, wheels, and smaller components, but can make assembly difficult. Surface preparation is important, and welding requires sanding the finish. Powder paint is a dry, colored powder that is sprayed onto a […]
Extrusion coating is a process that applies a thin layer of plastic to materials like paper, textiles, and aluminum foil. The plastic is injected into a slot mold and extruded onto the receiving material, then cooled and compressed. This process creates durable and high-quality products used in everyday applications like packaging. The plastics used are […]
Asphalt coatings are used to cover minor damage in driveways, parking lots, and pavements. The process involves leveling the old asphalt, applying a primer, crushed stone, and pouring asphalt concrete coating. Proper drainage and maintenance can prevent the need for coating. An asphalt coating is an additional layer of asphalt that covers imperfections in the […]
Conversion coatings are chemical or electrochemical processes that physically convert metal surface components into the desired finish, offering corrosion and wear resistance or a receptive layer for paints, dyes, lubricants, or adhesives. The most common conversion processes are oxide, phosphate, and chromate. Oxide conversions are used on various metals as a decorative and corrosion-resistant finish. […]
Powder coating is a durable, decorative, and environmentally friendly finish applied to various products. It is rustproof, scratch-resistant, and available in different colors and finishes. The process involves spraying electrostatically charged particles of powdered pigment and resin onto electrically grounded objects, which are then cured in an oven. Powder coating is cost-effective and ideal for […]
Plastic siding is a building material used on the interior and exterior of buildings. It can be made of polypropylene or PVC and comes in various colors and textures. It’s popular due to its low cost and low maintenance, but some have concerns about its safety and durability. Plastic siding is a type of building […]
Powder coating involves applying an electrically charged powder to a surface, which adheres until it hardens. There are three main types of powder coating systems: electrostatic coating with a spray gun, electrostatic fluid bed coating, and electromagnetic brush coating. The pre-treatment of the part, application of the coating material, and curing of the coated item […]
Color conversion coating protects metals from corrosion. It involves immersing metal in an aqueous solution of chromium salts and acid to form a thin layer of chromium oxide. The process works on aluminum but not iron or steel. Chromium coatings can self-repair minor scratches and are useful for painting. However, hexavalent chromium is toxic, and […]
Powder coating equipment includes electrostatic spray guns, fluidized beds, paint booths, and curing ovens. The fluid bed dipping process is an older method, while electrostatic spray guns are commonly used. Recovery systems can save money by reusing overspray. Curing ovens are necessary for thermosetting polymers. There are different types of powder coating equipment used for […]
PVC siding is a durable, waterproof, and versatile material used as a protective or decorative cladding over existing walls or structures. It is available in various shapes, sizes, textures, patterns, and colors, making it an ideal material for DIY projects. PVC siding is easy to install and maintain, and it is suitable for interior and […]
Dip coating applies a protective or decorative layer to products, often using plastic to protect metal items from rust and stains. The process involves cleaning the item, dipping it in hot plastic for a set time, and removing it at a constant speed. Dip coating can extend product life and add color. Dip coating is […]
Electrostatic powder coating is a finishing process where dry powder paint is applied to metal by using an electrical charge to create a high-quality, permanent finish. It is commonly used on metals and consumer goods, and can contain various materials. The process offers advantages such as reduced health risks and the ability to reuse unused […]
Nonstick coatings are made from silicone or fluorocarbon and applied in layers using spraying, curtain lining, or roller coating. The coating is cured at high temperatures and should have a matte, smooth surface with at least three layers. Use wooden or nylon utensils and avoid high heat to protect the coating. Hand washing is recommended […]
Powder coating requires a gun, powders, oven, plugs, tape, and cleaning solvents. It is a process of spraying a positively charged powder onto a negatively charged metal component, resulting in a durable finish. Powder coating is more difficult to repair than paint, but special supplies are available for DIY enthusiasts. There are many powder coating […]
Corrugated cladding is a strong and economical building material made of metal, fiberglass, or vinyl sheets set in horizontal or vertical patterns. Corrugations provide strength and stiffness to the material, allowing it to be secured with fewer studs or crossbars. Galvanized steel is the most commonly used material, but aluminum is preferred in coastal regions […]
Casing and liner strings are long sections of pipe used in oilfields to avoid drilling problems and maintain safety. Cement is used to seal the well and protect the integrity of the string. Steel is commonly used, with different grades for different drilling conditions. A casing string is a long section of tongue and groove […]
UV-curing coatings protect and decorate materials by reacting to ultraviolet light and creating new polymer bonds. They cure in seconds without high heat or toxic components, and can resist scratches, nicks, and weather damage. They can also be used for decorative purposes. Companies can formulate their own coatings or contract with specialized companies. UV-curing coatings […]
Spin coating uses a spinner machine to apply a thin film layer to a base material, commonly used in microfabrication and various industries. The process involves applying resin to the center of the base material and rotating it at high speeds. Resin viscosity, solid/liquid ratio, and temperature can affect the quality of the film. Rotary […]
