INFRARED CURVING

August 23, 2011

01-infrared curing process-infrared spectrum wave-conduction, convection, radiation

The coatings and paint industries strive to provide high technology coatings while reducing volatile organic compounds and energy consumption to produce a finished coating. Conventionally Convection ovens are used to cure the coatings. But this process which uses electric heaters is not an optimal process and is associated with various disadvantages.

01-coating surface absorption-infrared energy -infrared curing

Improved technologies are available today, which can either replace or improve the convection curing process. Infrared Curing is such a technology which uses Infrared rays emitted by an Infrared emitter to provide the required cure. Infrared curing applies light energy to the part surface by direct transmission from an emitter. Some of the energy emitted will be reflected off the surface, some is absorbed into the polymer and some is transmitted into the substrate.

01-reduced cycle times on final cure-eliminating manual rack up time

This direct transfer of energy creates an immediate reaction in the polymer and cross linking begins quickly once the surface is exposed to the emitter. Infrared emitters are often custom manufactured to suit the production demand. The various aspects of Infrared curing and convection curing and the possibility of combining these two technologies into a singe system will be discussed in this seminar.

01-infrared wave-infrared heating-infrared emitter-infrared curing

How it Works

Infrared heating is a direct form of heating. The source of the heat (the infrared emitter or lamp) radiates: energy that is absorbed by the product directly from the emitter. That is, the heat energy is not transferred through an intermediate medium. This is one reason for  the  inherent high-energy efficiency of infrared systems. For  example, hot air heating  first needs to heat air; the air then heats the product by convection.

01-infrared emitter-infrared curing systems

Infrared  energy is directed  to  the  product. When  the  product absorbs this energy, it is then converted into heat. Infrared energy is dispersed from the source in much the same  way as visible light. Exposed product surfaces easily absorb  the  infrared  energy and  become  heated. Therefore, heating effectiveness is related to line-of-sight between the source and the product. Depending on the coating and/or product substrate material, this heat is further thermally conducted.


01-table-characteristics of commercially used infrared heat sources

The ability of the product to absorb energy is also known as its “emissivity”. A theoretical body that absorbs all energy is termed a “black body”. A black body has an emissivity of 1. A highly reflective body would have a low emissivity value, approaching 0. (Reflectivity is the inverse of emissivity).

The potential of a product to become heated with infrared is related to the following:
• Watt density (total output power) of the source
• Wavelength (temperature) of the source
• Distance from the source to the product
• Reflective characteristics of the oven cavity
• Air movement and temperature in the oven
• Time product is exposed to the source
• Ratio of exposed surface area to the mass of the product
• Specific heat of the product
• Emissivity of the product
• Thermal conductivity of the product

CURING

Curing is a process of baking surface coatings so as to dry them up quickly. Curing is a broad term which means all the techniques employed for the finishing operations incurred during part production. Curing essentially involves either the melting of the coating or evaporation of volatile fluids present in the coating by the application of heat energy.

Curing is given to a wide range of materials both organic and inorganic. Usually curing is given to materials like ,

” Paints
” Enamel
” Liquor
” Powder coatings
” Varnishes
” Epoxy coatings
” Acrylic coatings
” Primers Etc.

Curing is also given to Rubber and Latex .The principle used for curing can also be used for drying rice and grains.

01-infrared technology-infrared-convection systems-tunnel system

CONVECTION CURING

Convection ovens are usually used for curing purposes. Traditional convection ovens use heated forced air to provide the necessary cure. Convection ovens consist of a chamber lined on the inside with Electric heaters. The shape of the chamber will be in accordance to the shape or geometry of the part being cured. A series of blowers circulate the heated air around providing the required cure. This process depends on convection to transfer heat from hot air to body surface and conduction to transfer heat to the interior of the surface. The air being delivered is held at temperature using closed-loop control, which provides predictable, repeatable results. Typically a temperature of around 250-500 degree Fahrenheit is required for paint or powder. Though convection ovens are widely used today they have certain disadvantages, which chokes the overall productivity of a company
Disadvantages of convection ovens :

” Fairly long heating times:-

Convection is a slow process. It takes a considerable amount of time for the heaters to heat up and raise the temperature of air to the required level. This causes a lag in the process and hence the curing time increases. Longer curing time spells reduced assembly line movement. This in turn reduces productivity.

” High energy consumption:-

A convection column dryer uses around 2000 BTU(British Thermal Unit) of energy to remove 1 pound of moisture. They use around 7.7 KW of electrical energy to dry a ton of rice. These are significantly larger figures for any company trying to bring energy consumption under control. The additional use of blowers and compressors further increases energy consumption.

” Large floor area required:-

Convection ovens are bulky in nature. Due to the presence of compressors and blowers, additional space is needed, which in turn increases the floor area requirement.

” Air circulation is required:-

Convection heating requires a medium for transmission of heat. Hence blowers are employed for good circulation of heated air. This increases the overall cost of the equipment.

HYDRATION SYSTEM

August 23, 2011

04-The Future Of Bicycling Hydration, Bicycle Mounted Hydration System, Hydration System Mounts On The Bicycle Rear

Is it possible to drink too much water during ride without stop the vehicle?

Adequate hydration is as important as calorie replacement to an athlete’s performance, yet dehydration continues to be a condition many experience. This is especially true in cycling where evaporative losses are significant and can go unnoticed. Sweat production and losses through breathing can exceed 2 quarts per hour. To maximize your performance pre-hydration is important, and it is essential that fluid replacement begin early and continue throughout a ride.

Approximately 75% of the energy your body produces is converted to heat rather than being delivered to your muscles to power your pedal stroke. Keeping your body cool and re-hydrated during exertion will result in greater efficiency, higher power output, extended endurance, and a quicker, more thorough recovery. Say good-bye to the Wet Spot!


Individual fluid and electrolyte needs are widely variable during physical exercise due to differences in metabolic rate, body mass and size, environmental conditions (e.g. temperature, humidity, wind, solar load, clothing worn), heat acclimatization status, physical fitness, activity duration, and genetic variability. Sweat rates can vary from 0.5L/hr to more than 3 L/hr. Similarly, sodium concentration may vary from less than 460 mg/L to more than 1840 mg/L

03-The Future Of Bicycling Hydration, Bicycle Mounted Hydration System, Hydration System Mounts On The Bicycle Rear

Technology:

Why use a perfectly good water bottle on your bike when you could use a complex, expensive and awkward to use “hydration system” instead? That’s the promise of the VelEau Bicycle Mounted Hydration System.

01-The Future Of Bicycling Hydration, Bicycle Mounted Hydration System, Hydration System Mounts On The Bicycle Rear

The VelEau comes in several parts. First, there’s a saddlebag which holds 42 ounces (1.4 liters) of water. Then there’s a tube through which you drink, much like those found on CamelBak water bags. This runs from under the seat, along the top-tube to the handlebars, where it is secured to a retracting cord on the stem. This cord pulls the mouthpiece back into place when you’re done drinking, where it is secured by magnets.

02-The Future Of Bicycling Hydration, Bicycle Mounted Hydration System, Hydration System Mounts On The Bicycle Rear

If that seems like it’s complex, unnecessarily heavy and annoying to use, that’s because it probably is. However, there is at least a compartment to carry a multi tool in the same bag, which adds some utility.

DISI ENGINE

August 23, 2011

02-direct-injection-engine-disi engine-gasoline engine

In developing the DISI engine, we aimed to cool the interior of the cylinder as much as possible by promoting fuel vaporization and uniform mixing of atomized fuel and air. This produces a high charging efficiency of the air-fuel mixture and a high compression ratio, which results in significant improvements in both torque and fuel efficiency.


Characteristics of the direct injection engine:

  • Fuel is injected from a tiny nozzle into a relatively large cylinder, so it has a high latent heat of vaporization, which efficiently cools the air within (in-cylinder cooling effect).

  • The air temperature in the cylinder decreases, which means:

  • (1) more air may be charged into the combustion chamber, which produces increased torque.

  • (2) the engine is less prone to knocking. This contributes to increased torque, and enables a higher compression ratio that also contributes to good fuel efficiency.


In a direct injection engine, however, the fuel skips the waiting period it would have to endure inside a standard engine and instead proceeds straight to the combustion chamber. This allows the fuel to burn more evenly and thoroughly. For the driver, that can translate to better mileage and greater power to the wheels.

In the past, direct injection posed too many technical hurdles to make it worthwhile for mass market gasoline automobiles. But with advances in technology and greater pressure to make cars run more cleanly and efficiently, it looks as if gasoline direct injection — or GDI as it’s referred to in industry lingo — is here to stay. In fact, most of the major car manufacturers make or plan to soon introduce gasoline cars that take advantage of this fuel saving and performance enhancing system.

Continuous improvement in conventional engines, including lean-burn gasoline engines, direct injection gasoline engines and common rail direct-injection diesel engines, as well as engines modified to use alternative fuels, such as compressed natural gas (CNG) or electricity (for Electric Vehicle).

Engineers may disagree about which fuel or car propulsion system is best, but they do agree that hybrid technology is the core for eco-car development.

“Plug-in hybrid” technology brings further potential for substantial CO2 emissions reductions from vehicles. It has a higher battery capacity and is thus more fuel-efficient than the current hybrid, assisted by the power of engine. For a short-distance drive, it could be run with electricity charged during the night. Depending on how electricity is generated, the vehicle could run with much lower CO2 emissions. In order to commercialize the plug-in hybrid, there is again a need for a breakthrough in battery technology. It is necessary to develop a smaller-sized battery with higher capacity. Plug-in hybrids could contribute to reducing substantial amounts of CO2 emissions from vehicles, as well as fossil fuel use, by charging from cleaner electricity sources in the future.

Challenges of increasing power performance

In order to improve the driving performance, its power train was completely redesigned. To increase motor output, a high-voltage power-control was adopted. Although this technology was used in industrial machines and trains, the idea of incorporating it into an automobile did not easily occur at first. First of all, the system itself would take up a substantial amount of space and secondly, there was no prior example of applying this method to a motor that switches between output and power generation at such a dizzy pace.

Once the development of the high-voltage power circuit began, there was a mountain of problems, such as what to do about the heat generated by increasing voltage and the noise generated. To reevaluate the power train, the project team had to produce prototypes and repeat numerous tests. The prototyping stage went to seven prototypes instead of the usual three, and the total distance driven by these prototypes during testing exceeded one million kilometers.
