Paintshop : Through all the advancement in automotive design and manufacturing over the years, there has been one constant – vehicle’s aesthetics is a critical factor in a consumer’s purchasing decision. Vehicles’ finish consistency, quality and variety play the foremost role during a purchase.
One of the biggest changes in automobile paint, aside from the sheer variety of colours available to modern consumers, is that the coating on the surface is more than just aesthetic! In an auto industry that is more competitive than ever, a process control technology which ensures and enhances quality directly affects profitability and market share.
Cathodic e-coating gives the car body a primer coat. It protects the car from corrosion, especially the cavities of the body that cannot be reached easily by spray application.
Primer: evens out any irregularities of the underlying layer. It can be sanded easily and provides a smooth surface.
Basecoat: gives the main color to the piece, therefore it plays a significant role in establishing the final visual impression.
Clearcoat: seals everything else and is applied last. It protects the car from external elements like snow, UV radiation, dirt, etc.
Paintshop oven : Paintshop oven Industrial ovens are heated chambers used for a variety of industrial applications, including drying, curing, or baking components, parts or final products. Industrial ovens can be used for large or small volume applications, in batches or continuously with a conveyor line, and a variety of temperature ranges, sizes and configurations.
An industrial oven is a heated chamber that is used to perform a wide range of applications within industry. Generally, industrial ovens process a raw material at extremely high temperatures to perform a heat treatment process. Typical applications for industrial ovens include food production, chemical processing, and even the electronics industry. This blog post will discuss some common industrial ovens and their applications.
Curing Ovens : Curing is a heat-treatment process that is used to accelerate a chemical reaction. Curing ovens perform this process by heating a raw material to a specific temperature in order to activate this reaction. Industrial ovens used for curing are used for a range of applications with raw materials including coatings, adhesives, and rubber. A method for curing a paint coating applied to a workpiece includes applying radiant light energy to cure the paint coating on surfaces of the workpiece within a line of sight of a radiant light energy source, and applying ambient air to the workpiece to cure the paint coating on surfaces of the workpiece not within the line of sight of the radiant light energy source.
Drying Ovens : A drying oven is designed to remove any moisture from the raw material placed within it. These industrial ovens undertake a three-step process; first is the heat-up, where the material is heated to the temperature required to remove the moisture in a specified time. The next stage is the soak, this is where the material is left to ‘soak’ in the heat for a specific amount of time. Finally, the oven has a cool-down stage, where the heated air is exhausted from the oven and cooler ambient air is fed in. Drying ovens can also be used for sterilization, incubating temperature sensitive experiments, and temperature testing.
Batch Ovens : A variety of different heat treatment processes can be performed in a batch oven, including curing, drying, aging, and annealing. Batch ovens are used when the same heat treatment process is required to be performed at different times, and if the raw material to be processed changes between batches. Depending on the production requirements, the batches of raw materials can be placed inside the industrial oven on carts, racks, or trucks. Manual or automated loading can also be accommodated if required.
Continuous Ovens Similar to batch ovens, continuous ovens can perform a range of different heat treatment processes. This type of industrial oven is chosen for mass-production of the same raw material in a consistent heat treatment process. Continuous ovens often have separate heating and cooling chambers, which helps to speed up the heat-treatment process as you do not need to wait for a single chamber to cool down. Processing time is often reduced in continuous ovens, and the final results are always consistent.
Curing ovens : Designed to cause a chemical reaction in a substance once a specific temperature is reached. Powder coating is one common curing oven use.
Drying ovens : Designed to remove moisture. Typical applications are pre-treating and painting. Such ovens are also sometimes known as kilns, though they do not reach the same high temperatures as are used in ceramic kilns.
Baking ovens : Combines the function of curing and drying ovens.
Reflow Ovens : A reflow oven is a machine used primarily for reflow soldering of surface mount electronic components to printed circuit boards (PCB).
Batch ovens : Also called cabinet or Walk-in/Truck-in ovens, batch ovens allow for curing, drying or baking in small batches using wheeled racks, carts or trucks. Ovens such as this are often found in large-volume bakeries in places such as supermarkets.
Conveyor or Continuous Ovens : Typically part of an automated conveyor processing line, conveyor ovens allow for higher volume processing. Heat tunnels are an example.
Clean room ovens : Designed for applications requiring a cleanroom, such as a semiconductor manufacturing or biotechnology processes.
PT Tanks : Process tank means a vessel or other container used for the mixing or batching of chemicals, feeds, wastewater, or other components, or for the preparation of one (1) or more components, leading to the production of a desired product.
Combustion chamber : Its a closed space inside an engine in which fuel is burned. What is burner in combustion chamber? It is also known as a burner, combustion chamber or flame holder. In a gas turbine engine, the combustor or combustion chamber is fed high-pressure air by the compression system. The combustor then heats this air at constant pressure as the fuel/air mix burns. As it burns the fuel/air mix heats and rapidly expands.
Scrubber for paintshop : Scrubbers are devices to control air pollution and used to remove some particulates and gases from industrial exhaust streams. A scrubber assembly for removing particulate paint from a flow of air through a paint application booth is disclosed. A sheet of water received from a water source flows over flood pan collecting paint particles suspended in the flow of air. A separation chamber receives air and particulate paint from the booth and water from the flood pan through first and second scrubbers. The first and second scrubbers extend downwardly from the flood pan. Each scrubber includes an inlet receiving air and particulate paint from the paint application booth and water from said flood pan. The first scrubber includes a first outlet discharging a first stream of air, particulate paint, and water received from the first inlet. The second scrubber includes a second outlet discharging a second stream of air, particulate paint and water received from the second inlet. The first and second streams intersect within the separation chamber.
Dump Tank :
A separate collection and containment vessel intended to receive an emergency discharge of liquids, liquid reaction mass, or slurries originating from the bottom of a process vessel or reactor.
The dump is usually automatically triggered by a process safety interlock, but may also be initiated manually.
Heat Exchanger :
Heat exchangers, metal shells and tubes, work by transferring heat from one place to another. When a furnace burns natural gas or propane fuel, its exhaust/combustion by-products (also known as flue gas) enter and travel through the heat exchanger.
Types of Heat Exchangers :
Burner : A burner is a device designed to ensure that the flame is stabilized by establishing a suitable flow field to produce the initial temperature rise. The flame is used as the source of heat to preheat the fuel / air mixture to the ignition temperature. Burner types
A regenerative thermal oxidizer (RTO) : is a type of air pollution control equipment that destroys hazardous air pollutants (HAP), volatile organic compounds (VOC) and odorous emissions created during industrial processes. RTOs are the most common air pollution control technology in use today. RTO technology uses combustion at high temperatures to oxidize air pollutants from industrial exhaust streams, which turns them into CO2 and H2O before they’re released into the atmosphere. The term “regenerative” in regenerative thermal oxidizer comes from the ceramic media heat exchanger, which retains heat from the prior combustion cycle to preheat (and partially oxidize) the pollutant-filled airstream for the next cycle.
