Cleaning Methods: Industrial Chemical Wipes, Aqueous, Non-aqueous and Vapour Degreasing

Posted on: July 8th, 2013 by canadianfinishing No Comments

Modern manufacturing operations require careful attention to detail and exacting standards. When it comes to surface finishing, the first step to any successful process is ensuring that parts are completely clean. Each application requires its own cleaning process and there are a number of different techniques and technologies that are utilized to ensure that all parts are as free as possible from foreign material and contaminates to ensure proper adhesion once the finishing process begins.

 

Industrial Chemical Wipes

 

 

For lighter duty cleaning, there are a number of methods that involve industrial chemical wipes. Specially woven cloths are coated with solvents which can then be applied by hand to individual parts. Industrial chemical wipes are ideal for smaller-quantity jobs where special care can be taken with each individual item to be cleaned. Most industrial chemical wipes are not reusable and must be handled properly to prevent contamination or improper disposal. In general, industrial chemical wipes are often only one part of a more thorough cleaning process.

 

 

Aqueous Cleaning

 

 

Aqueous cleaning involves using water in a solution with certain chemicals to remove grease and other contaminants. In aqueous cleaning, the water-based solution acts on the foreign material and then heat or agitation is applied to remove the impurities from the surface and wash them away.

 

 

Non-aqueous Cleaning

 

Non-aqueous cleaning, as the name implies, relies on solvents in a non-water based solution. These solvents act to dissolve and remove the foreign material chemically. Parts may be dipped or submerged in the solvent to ensure complete coating.

 

 

Vapour Degreasing

 

Vapour degreasing uses heat to create solvent vapour which acts on the parts being cleaned. Rather than being submerged directly into the solvent bath, parts are hung above a heated basin of cleaning solution. The resulting vapour condenses on the parts, dissolves the contaminants and then drips away.

 

Every finishing process requires its own unique cleaning regimen and Canadian Finishing Systems has the experience to assist you in choosing the proper methods for your application. Our products meet the highest of specifications, including Aerospace specifications.  For more information about the services available from CFS, use our contact form or visit our website.
