Cleanliness Analysis

You cannot control that which you do not measure.

In more and more industries, the exact knowledge of particle contamination is gaining in importance. Contamination of materials in dimensions of a few micrometers was mainly of concern for the pharmaceutical and semiconductor industries. However, not only manufacturers of circuit board components, but also traditional car parts suppliers face new demands on particle recognition and contamination source identification.

Cleanliness for the automotive parts manufacturers has become a huge topic in today’s ever challenging continuous improvement world. The need to define, measure and control the levels of particulate contamination on product is the new norm for suppliers and automotive OEM’s.

Cleanliness directly relates to product warranties, reliability, performance and safety issues. It has long been known that a dirty product gives us poor quality and low life expectancy. The dirtier the transmission from new, the less time it will last.

It is crucial now to identify particles and their source so that effective elimination can be achieved. Residual contamination consists of particles that persist on the component’s surface after the final step in manufacturing. Such contaminants are introduced via parts from suppliers or arise during processing. After vehicle assembly, the contaminant particles can cause severe damage, loss of function or reduce the lifetime of the product.

Cleanliness is defined as the contamination level of a component surface. Common measures to quantify the cleanliness are mass of the contaminants as well as number, size of the dirt particles. In general, the customer will specify contamination limits. The supplier then has to maintain these levels and document them regularly by means of contamination analysis.

The analysis of the contamination has to be proven to not affect the result and to be effective in evaluating all the contamination present. Methods of extraction and evaluation are specified in the international standard ISO 16232. Particular attention must be paid to the extraction method to ensure no contributing factors are introduced to the evaluation. There are different methods of counting the resulting extracted particles but by far the most accurate, repeatable and cost effective is automated microscope analysis. The microscope with software can scan the filter membrane; sort the particles by size class and even determine basic material composition (metal, non-metal, fiber). Once the data is gathered a custom report can be generated based on the customer requirements.

Go Green With Natural Finishes

Finishes are coatings that are  applied to the external and inside surfaces of walls to protect them from the elements and from wear and tear.  They also improve the appearance of the structure and are used to enhance the design of rooms.

Petroleum, our main source of oil-based wood finishes and paint, is a non-renewable resource.  There are now paints and finishes on the market that are derived from a renewable resource, which  in a small way, helps to reduce dependence on oil, and  contributes to a more sustainable world.

The basis for these products is whey, which is a product of cheese making, and which has a high biochemical oxygen demand (BOD).  This increases the burden on waste treatment facilities, and can also pollute our natural water sources.  In the last ten years, this by-product has been used for many new purposes, one of which is natural wood finishes.

When choosing paints for your decorating, use the low or no VOC (volatile organic compound) paints. For hundreds, no, thousands of years, earth, clay and lime have been used, both in hot and cold areas of the world.  And now this knowledge is being readapted for contemporary use. If you do any redecorating or new building, it makes sense to contribute to having green, healthy surroundings.

Low and no VOC paints have less smell and less impact on air quality.  EPA studies have shown that indoor air quality is up to five times more toxic than outdoors, mainly because of toxic emissions from paint and finishes. This particularly affects anyone with allergies, asthma, or chemical sensitivities. With the new “green” paints, there will be lower contamination of landfills, groundwater, and the ozone.

Switching will not cost you more.  Cleanup is easily done with soap and water, instead of toxic chemicals, and brushes can easily be cleaned and reused.  The paint is still washable, and is far less harmful to you, your pets, and the environment.

Some Eco-Friendly Green Thoughts

How often when you go to the grocery store are you asked if you want paper or plastic grocery bags?  Well the best answer to that would be NEITHER.  To keep the U.S. stocked with paper and plastic grocery bags, takes about fourteen million trees and twelve million barrels of oil every year! Investing in a few reusable bags makes a lot of sense.

Think about those little paper receipts you get at the gas pump and the ATM machine.  If all people would simply note it in their checkbook, or in a small notebook when they made a purchase or withdrew money, it would be saving enough paper to encircle the globe fifteen times!

If every American would by one roll of recycled paper towels instead of the others, it would save over half a million trees. And how about turning the car off when you are waiting for someone, in the drive-thru lane  or stuck in a huge traffic jam?  When a car idles for more than a minute it is polluting the air and wasting your gas.

Cordless phones are replacing conventional phones.  But think about it… sitting in a recharging cradle and using up your electricity  twenty-four hours a day and every day of the week! Replace one or two cordless phones with your old conventional ones and you’ll save energy.  The old fashioned ones use only a tiny bit of electricity, and will work when the power is off. If you insist on the convenience of cordless phones, make sure the ones  you do get are Energy Star-rated, for high energy efficiency.

Proper Installation of Wind Turbines is Very Important - Always Rely on Professionals

The most efficient and economical way of using wind power to light up your home is to install a windmill or wind turbine as they are also called. The current trend is to use green energy to supplement energy generated from fossil fuels to ensure uninterrupted supply and protection of the environment.

Wind turbines of different sizes are available for your different requirements. If you live in an area where the average wind speed ranges around 10 to 12 miles per hour, you can install a wind turbine to generate electricity throughout the year. Depending on your energy requirements, you can opt for the right sized wind turbine starting from 2Kw units to even 20 Kw units.

Choosing a wind turbine manufactured by a reputed maker is essential but your task does not end there. You should choose the right contractors for installation of the wind turbine. Proper installation of wind turbines is very essential because of the following reasons.
• Installation of a 42 feet or more structure is not a simple task. The installation must be perfect to ensure that there are no safety concerns. Even the smallest flaw in installation can have severe consequences.
• A wind turbine may look like nothing more than a fan attached to a long pole. However, it is a complex and delicate mechanism that can be damaged with careless handling and improper installation. This can render your entire investment totally waste.
• The fans of the wind turbine may seem to be revolving very slowly from ground level. However, the height and the weight of the fans combined with its velocity can cause a lot of damage if breakage or other malfunction occurs.
• It is common to make use of the land beneath a windmill for other purposes. If you ensure that the wind turbine is safely installed, you can set up structures under the wind turbine without any fear of accidents and injuries.
• Setting up a wind turbine for your home will ensure that your energy requirements are taken care of forever. However, this requires a high initial investment. Improper installation will mean that your entire investment goes waste without sufficient benefits. What is the point of sinking thousands of dollars into your windmill if it conks off within a few days and you have to spend more repairing a faulty installation?

Hence, you should always deal with professional wind turbine contractors who know what they are doing. How to identify reliable contractors from all those who claim to be the best? For starters, all professional contractors who take up such projects of green energy offer a free quote. They do not charge for a quote which helps you estimate the cost of the project. Rather, they would be more than happy to offer the quotes for free.

Another way to identify professional service providers is to take a look at the spares and materials they use. Professional wind turbine installers will never use counterfeit material to reduce cost.

They follow strict safety codes and comply with all professional standards at all times. The net result of dealing with such installers for your green energy requirements is that you are assured of the best service at all times.
