Phosphate coating is a treatment for metals, where a layer of phosphate from another metal is applied to provide corrosion protection. The coating provides a stable base for other coatings and treatments. Zinc, manganese, and iron are used for phosphate coatings, and oil is often applied for additional protection. Phosphate coating is useful as an […]
Diesel ethanol, or E-diesel, is a fuel made from diesel and ethyl alcohol. It has benefits such as higher fuel efficiency and lower carbon emissions, but is not widely used due to safety risks and reduced truck performance. Precautions can be taken to reduce risks, and research is ongoing to improve safety and sustainability. Diesel […]
Environmental sanitation aims to improve the environment and reduce disease. Water and waste management, pollution control, and noise reduction are all part of it. Proper disposal of household and industrial waste, clean water supply, and reducing air pollution are ways to improve health. WHO provides guidelines for effective environmental hygiene programs. Environmental sanitation is a […]
Longwall mining is a mechanized underground coal mining technique that uses machines with coal clippers mounted on hydraulic ceiling mounts. It accounts for over half of US coal production and can extract up to 30,000 tons of coal per day. The technique replaces the room and column method and is feasible for deep mining. However, […]
Porcelain is a hard, translucent white ceramic that originated in China in the 600s and Europe in the 1700s. It is often associated with delicate plates, cups, and vases. The technique of making porcelain involves combining white kaolin clay with ground granite and cooking it at high temperatures. European attempts to replicate it led to […]
A centrifugal switch uses centrifugal force to open or close electrical contacts when a machine reaches a set rotational speed. It consists of spring-loaded weights and switch plates, and is commonly used in starter circuit breakers and split-phase electric motors. A centrifugal switch is a device designed to open or close a series of electrical […]
A cold chisel is a tool for cutting unheated metal, usually made of hardened steel. It is less accurate than cutting machines but useful when they are unavailable. Different types of cold chisels exist, with the most common being the flat chisel, which can also be used for masonry work. They come in various sizes […]
Acoustic sealant is used to reduce sound transmission in buildings and can be used on various materials. It is flexible and can be used in environments where there is expansion and contraction. It is used in a range of environments, from recording studios to hotels. Acoustic sealant is a type of sealing agent used to […]
A heat wheel is a rotating device used to reduce energy consumption in air conditioning by flowing hot and cold air streams through opposing halves. It balances temperatures and reduces equipment size and long-term costs, but requires adjacent air streams, cleaning filters, and maintenance. It is best used in places with a large outside air […]
Label makers dispense or print labels for various items, with a wide range of models available for different applications and industries. They can be manual or automatic, portable or heavy-duty, and designed for personal or professional use. Mid-range options are available for home business owners. A label maker is used to dispense or apply labels […]
Electrical wiring carries electricity and varies based on purpose, location, and amount of electricity needed. Wires are made of copper and insulated with materials like plastics and fibers. International standards exist for wire types and color coding. Outdoor wiring must withstand the elements. Fiber-optic and Wi-Fi systems may replace traditional copper wire in the future. […]
A tailstock is a device found on lathes and milling machines used to turn metal between centers, improve accuracy, and prevent vibration. It consists of a body, adjustable base, feed screw, and handwheel. It can also be used for drilling, reaming, and threading tasks. A tailstock is a device found on both power and wood […]
Buying used tires can be a good option for those on a tight budget. Look for tires with sufficient tread depth and uniform wear, sturdy sidewalls, and the same tread pattern. Retreads are an option, but used tires with enough tread are a safer choice. Many garages and tire shops offer good quality used tires […]
Pecan wood is a hard, fine-grained wood with a golden to cream color and reddish heartwood. It is primarily used in the United States for finishing, such as floors and counters. However, it has a high moisture content and can shrink dramatically, which can create problems. It can also be used for smoking and cooking […]
Splice plates are used to reinforce connections between steel beams in construction. They help improve safety and prevent structural failure. Splicing is used when long beams are not available or difficult to transport. The plates are pre-drilled and bolted onto the joint, distributing forces and reducing the risk of deformation. Building codes provide specific requirements […]
White pine lumber, derived from eastern white pine, is a durable and popular wood used for centuries in construction, furniture, and shipbuilding. It comes in graded and common classifications and is known for its strength, durability, and lack of knots. White pine lumber is a popular type of wood that is derived from eastern white […]
Tube banks are heat exchangers used to cool or heat fluids or gases. They are popular worldwide and can be custom-designed. The efficiency of the device depends on the number and size of the tubes. Tube banks are used in air conditioning, refrigeration, and industrial applications. The size and material of construction are considered during […]
Optical measurement uses sensors to collect measurements without touching the object. It is precise and fast, but automated systems cannot correct errors like humans. The cost varies and companies offer information on their products’ applications and features. Optical measurement is a measurement technique that relies on the use of optical sensors to collect measurements. There […]
Cotton pulp is a pure form of cellulose used to manufacture high-quality paper and filter materials. It is produced from cotton waste and undergoes a pulping process involving chemicals and water. The resulting pulp is free from lignin and acid, making it more stable and reliable for archival purposes. The process involves sorting, chopping, and […]
