The Advantages Of Utilizing A Modern Asphalt Extraction Solvent

Posted on: December 6th, 2013 by canadianfinishing No Comments

Modern roadway technology has made great strides in the last few centuries, perhaps none as revolutionary as the development of asphalt. Today, while it’s also utilized in a number of different forms for other uses like waterproofing and roofing, it’s still primarily recognized as a paving product and is laid down by the truckload every day around the world. One of the major advantages of this ingenious material is also one of the things that makes it difficult to work with. Its highly viscous nature and impressive strength when hardened make maintaining the tools used to apply it a particular challenge. That’s why scientists and engineers continue to develop new compounds of asphalt extraction solvent, and why today’s products have a host of valuable advantages over their predecessors.

 

A Safer Asphalt Extraction Solvent

 

Many early asphalt extraction solvent products contained trichloroethylene (TCE) and/or methylene chloride (MeCl). Both compounds are toxic and pose serious health risks to road workers who are exposed to these compounds for long periods. Today, manufacturers like BIOACT® produce an asphalt extraction solvent that is non-toxic and USDA Certified Biobased.

 

Less Harmful To The Environment

 

The harsh chemicals in many early lubricant and removal products were not only harmful to workers, but also contained environmentally dangerous compounds as well. Today’s products often contained citrus-based terpenes & surfactants and are both biodegradable and non-ozone depleting.

 

Easier to Work With

 

As the technology for applying paving aggregates has evolved to make the process quicker, easier and more efficient, the cleaning and degreasing products have had to follow suit. Many modern solvents are water soluble and can be utilized quickly and easily, minimizing downtime and avoiding elaborate decontamination steps.

 

Versatility

 

Perhaps the greatest advantage to these modern solvents is their versatility. Not only can they be used for extraction at full strength, but many can be diluted up to 30:1 to suit a wide range of needs from lubricating surface contact machinery to preventing adhesion in truck beds.

Three Applications For Vapour Degreasing Solvents

Posted on: October 23rd, 2013 by canadianfinishing No Comments

As the name implies, vapour degreasing is a method of surface preparation in which parts are cleaned of contaminants using suspended vapour. Vapour degreasing solvents are heated in a chamber below the piece to be cleaned. The heated vapour condenses on the cooler surface of the part where it dissolves and captures the contaminants which then drip away. In some instances agitation may be applied to remove stubborn debris. Here are just a few applications for vapour degreasing solvents.

 When Other Surface Preparation Methods Might Cause Damage

 The use of vapour degreasing solvents is ideal in instances where aqueous (water-based) cleaning methods would be impractical or potentially harmful to the materials being cleaned. Vaporized solvents can be used to eliminate oil, grease, flux, wax and other non-water soluble debris that aqueous cleaning methods might struggle to remove. The process avoids the potential for both oxidation and detergent buildup on materials that might be especially sensitive to such secondary contaminants.

 Using Vapour Degreasing Solvents On Small Or Intricate Parts

 Because the solvents are suspended in a vapor, they are able to penetrate into tiny holes, recesses and cracks in the parts to be cleaned. This makes the process ideal for smaller components of electronic subassemblies, both metal and plastic as well as any other materials that might be difficult to thoroughly coat with more traditional liquid solvents.

 Finishing Preparation

 Degreasing is often the first and, some would argue, most important step in the finishing process. In order to ensure a uniform and pristine finish, all surface contaminates must first be removed and vapour degreasing solvents leave properly prepared for painting, coating, welding or any other finishing technique.

 Every cleaning and finishing process requires its own unique combination of techniques and materials. Canadian Finishing Systems can assist your business in choosing the proper methods and process for your application.
