Infomercial from Mitsuba

Will you bet on Asian Paints, Berger or Kansai Nerolac?
With the festival season round the corner, paint companies are expected to make hay. On the back of drivers like excellent growth in housing and auto sectors, the industry is already in a very good state. If one looks at the three major paint companies, viz; Asian Paints, Berger Paints and Kansai Nerolac, together they have reported a growth in excess of 14% in the first quarter of FY07.<more>

‘Tajmahal of MP’ dazzles again
The ‘Tajmahal of MP’ – the Hoshang Shah’s tomb at the hill fort complex of Mandu in Dhar district – is back to its dazzling days, thanks to a technology developed by the Archaeological Survey of India.

The chemical wing of the ASI’s MP Circle has used a ‘composite polishing technique’ to restore the original sheen of the 15th century tomb.

The breakthrough restoration technology, developed by the chemical wing and used for the first time in the country, has also given the monument an additional surface strength to bear the vagaries of nature.

“We decided to use Oxalic acid. The acid not only helped cleaned the ingrained grime but also formed a very thin protective layer of Calcium Oxalate on the monument – a formation that is far stronger than Calcium Carbonate (the original composition of the marble),’’ Dr Chaturvedi said.

Berger hints at paints price rise
Sharp and consistent increase in crude oil price is significantly hitting the margins of every Indian paint company and the industry may see a second price hike in the current financial year, in the solvent based products shortly.

Subir Bose, managing director, Berger Paints said, "There is an urgent requirement of price increase in solvent based products by another five per cent. The price hike is expected during the second quarter." <more>
 Asian Paints  will have another price hike by September
In an interview Ashwin Dani, VC & MD at Asian Paints informs that Asian Paints is planning a price hike, mostly by September, in the wake of rising crude oil price. He said " We did have one price hike in the middle of June, this year. We increased the prices of solvent-based paints by 2%. So if you consider the weighted average increase across the entire paint segment it would amount to 0.7%.

There has been some further increase in the prices of various petrochemicals in line with the increase in crude price, which is hovering around USD 76-77. We are definitely expecting a price hike and it will be during the second quarter. I expect a price revision in solvent-based paints by September 1.

At the moment, it is undecided. All we have decided is, that there would be price rise with effect from September 1, but the quantum of the rise remains to be worked out." <more>

Nippon Paint plans new manufacturing units by 2008
Coatings Flash - August 28, 2006
Nippon Paint of Japan, which launched its India operations from Chennai last month, will go pan-India staring up manufacturing facilities in the first quarter of 2008. "We will go to Kerala and Karnataka next", announced Ramakanth V. Akula, Vice-President  (Decoratives) of Nippon Paint India. He added that the company would commence two  manufacturing facilities, one each in Gurgaon and Chennai, early in 2008. It would spend INR 1,600 million (INR 1 = EUR 0.02) on the facilities, each having a capacity of 20,000 tonnes - with a scope for upscaling to 40,000 tonnes. Ramakanth said the INR 90,000-million paint  market offered great opportunities. While the organised market comprised 70 % of the total paint market, decoratives held a maximum share of 75 % (INR 47,250 million). The company will first offer products in the decorative range, but will soon introduce other products, too.

  Powder Coating Manual, Air Management-- (Part - 56)  

There are significant benefits to building pressurization. Pressurization  occurs when air is blown into the building through a heater that is designed to supply make-up air. It is similar to blowing up a balloon with holes. The heater provides the air and the environmental control needed for effective operation of the powder system. In a building that is pressurized the introduction of air to compensate for exhaust is all through a single controlled point, the building air handling system. All of the air required to make-up for exhausted air  and provide building heat or ventilation can be treated for heating, cooling, control of humidity and filtration. It is pushed to outside walls, creating equal pressure and comfortable environmental conditions throughout the building.

In order to pressurize a building, all replacement air for mechanically exhausted air is passed through the air handler along with an additional volume to counter the effect of wind and temperature-induced infiltration.

A building that is under slight positive pressure will fight the natural effects of the wind outside the building and reduce cold air drafts into the facility. At open dock doors a pressurized building will allow a “bubble” of cold air to enter the building, compared to the “river” of cold air that enters a building when air pressure is negative. Pressurization produces a buffer to push heat out towards the walls of the
building and reduce the natural effect of outdoor wind and cold. Pressurization needs vary due to the dynamics of the building. The total air volume may need to be changed as the wind direction and velocity shifts, doors are alternately opened or closed, and fans are cycled on and off. The optimal control strategy can respond to these changes and adjust the air volume through a pressure loop control system.

Some people think that a building that is heated by pressurization will  consume more energy than other heating systems. It is important to understand that a non-pressurization heating system depends on infiltration of cold air. Two problems occur that increase the use of energy in these type of systems;

1. There is a lag between the time that the cold air infiltrates and the time that it takes to heat it up so the building cannot consistently reach and sustain the desired temperature.

2. As the warmed air exits the system it rises and the cold air migrates at lower areas of the building creating stratification of temperature. The discomfort that results from this arrangement and the inefficiency of indirect heating will actually mean higher energy cost than a directfired
pressurization system.The first step in dealing with the air needs of the powder system is the understanding of air-make-up heaters (AMU). An AMU is a device that supplies air and heat to the building. It provides air to compensate for the mechanical exhaust of the system equipment, preventing the negative air pressure inside that causes infiltration.

The AMU creates a slight positive pressure in the building (normally 0.01” water column/0.25 kg/M2). This pressurization creates a balance of the air being exhausted and the supply air. It allows the fans to perform without the problems associated with negative air pressure. It provides a lot of benefit that is often overlooked or poorly understood  by coating system managers and owners. Pressurization combats other forces of nature that are detrimental to the powder system and the IAQ of the building.

The Benefits of AMU
There are many benefits to using AMU. The benefits listed below should encourage coaters to consider AMU to be an essential component to the success of a powder coating operation.
• prevents nuisance flame-outs of gas burners
• prevents back-drafts down exhaust stacks
• helps the fans in the system perform as intended without interference from crossdrafts
• prevents condensation on building steel, reducing the potential  or dirt in the building and preventing rust
• provides uniform temperature in all areas of the building for optimum  worker comfort and equipment performance

Direct Gas Fired Heating vs. Space Heaters
In addition to all of the benefits mentioned, an AMU heater is the most economical way to provide building heat. How is this possible? It’s really very simple.

A direct fired system inherently puts 100% of the available heat into the air-stream. Indirect fired systems always have a chimney or flue that exhausts hot combustion gases out of the building and into the atmosphere.

The space heater has an initial peak efficiency level of around 56%. This is because approximately 20% of the fuel is lost in the flue gasesand additional fuel is lost to the heat exchanger, which is around 70% efficient when new. The heat exchanger breaks down over time and the efficiency level can drop to 40 to 50% overall efficiency. Not only is the space heater inefficient, it cannot provide uniform temperature because it depends on infiltration of cold air for combustion. The combustion process requires approximately 10 parts of atmospheric air to 1 part natural gas. There is approximately 1000 Btu in a cubic foot of natural gas. A typical building may lose approximately 3,000,000 Btu/hr. in normal heat loss. This means that the space heaters will draw 3,000 cubic foot of combustion air every hour.
This infiltration air for the combustion process must be heated so it adds to the normal building infiltration load. The cost for just the combustion air to support the space heaters is around $0.95/hr.  Unlike the space heaters, the AMU heater does not bring cold air into the building for combustion. It also does not exhaust heated air. In a pressurized atmosphere, the temperature is much more uniform. The AMU heater does not use a heat exchanger, it does not exhaust and it does not bring cold air into the plant. The gas burner modulates according to demand and the efficiency approaches 100%. All of the heat value of the spent fuel is delivered directly into the building. Natural gas contains 8% water. During combustion, the natural gas generates “sensible heat” that contributes to temperature rise in the building. The water present in the gas generates “latent heat” that provides humidification in the plant. With a space heater, the latent heat is lost up the stack.

Without AMU, the natural force of the wind combines with the mechanical exhaust of the building to set up a situation where cold air enters and warm air exits. Cold air collects around the floor and warm air rises to the ceiling. Wasted energy collects around the ceiling while workers have cold feet at floor level. All of the burners are reacting to the cold air drafts along the floor, firing higher to offset the infiltration
of cold air.

Positive pressure from an AMU provides controlled displacement ventilation The building still breathes but now the air is fresher inside and the temperature is even. The fresh air from the AMU pushes out stale air and contaminants. The volume of air being displaced is controlled. Exhaust systems in washers and ovens work at the design volumes without nuisance flame-outs or back-drafts. The “wind-tunneling” through the equipment that can occur with space heaters is eliminated. And the cost is 20 to 40% less than it is with indirect space heating

Infiltration causes severe stratification of temperature. The floor is very cold, especially around dock doors and areas with poor protection from the outside. Space heaters, often used to heat a building, will run forever and never raise the temperature to an acceptable level in the really cold areas. Space heaters get their air for combustion from the cracks in the building. As the cold air enters, there is no
possible way for that area to warm up. Instead, the heated air from the space heater rises to the ceiling along with the heat from the ovens and the washer. The floor may be around 45 °F while the ceiling is around

120 °F (5° to 49 °C) or higher. The space heater continues to run in an impossible effort to raise the temperature at floor level to a comfortable level. Cold air continues to infiltrate and Btu’s are consumed and lost as heat rises and cold air infiltrates. So the direct fired air-make-up heater is different and more efficient than space heating. The air for combustion enters the heater, is raised to the set-point and blown into the building for efficient transfer of energy. Since the building is pressurized, the heat is much more uniform throughout. That 120 °F air that was lost up around the ceiling is now spread out around the plant, contributing to overall uniform comfort In contrast to the space heater that allows continuous infiltration of cold air, the AMU takes just enough outside air to satisfy the building
needs, raises the temperature to the desired set-point and distributes it evenly throughout the building. The burner modulates to provide only what is needed, no more, no less.
