Wet Blasting Technology, Part 2 – Comparing Attributes, Advantages to Dry Blasting

1 Comment

Unlike dry blasting in which only solid abrasive media is used, wet blasting processes use a slurry in which the media is embedded in water. This greatly cushions the impact energy on the work pieces, providing gentler, yet effective results for delicate work pieces.

As the utilization of wet blasting increases, Rosler reminds manufacturers to review their traditional, dry shot blasting applications and consider if wet blasting could provide additional efficiencies, reduced costs, and better results.

Understanding the Differences

As in any surface finishing process, the starting condition of the work piece, its material composition, shape, and final finish largely dictate which finishing application is most appropriate. Understanding how the application changes the work piece is a key consideration.

PureFinish® Stainless Steel Treatment For Optimum Hygiene

Leave a comment

PureFinish® is a post-processing technique.  This technique allows stainless steel to be finished to a smoother surface with a low and reproducible SRI value below 0.010.  In practice, this produces a surface with a very low degree of adhesion characteristics. The PureFinish® treatment has been extensively tested by TNO. TNO, a Dutch organisation is the leading institute for Applied Scientific Research.  The SRI value (Soil Retention Index) was investigated because this parameter most accurately describes the relationship between surface structure, contamination and cleanliness.

Within the food and pharmaceutical industries hygiene is a top priority, not only for safety but also to prevent contamination and to ensure the quality of the product in terms of taste, aroma and appearance.  The occurrence of contamination through bacteria, proteins or other elements must therefore be prevented.  Process plants require a defined, homogeneous and reproducible surface for all parts that come in contact with food, beverage and pharmaceutical products.

The Optimisation Of Stainless Steel Surfaces

1 Comment

Over the decades researchers have searched for optimal and efficient techniques to adequately recondition the surface of stainless steel after it has been subjected to various processes. This article examines the various processes currently used and the surface conditions achieved. An independent study has shown that water jet blasting may offer the best solution in terms of both the degree of smoothness achieved and the avoidance of using chemical products.
