PureFinish® Stainless Steel Treatment For Optimum Hygiene

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

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.

Applications for dry and wet / vapour blasting machines

To understand what dry and wet / vapour blasting is please see our blog: Blast Surface Preparation and Finishing – What Is It And Why Should We Consider Using It?

Introduction

Blast finishing and surface preparation are very widely accepted processes within manufacturing and service industries. Each application has its own unique reason for and why a specific treatment is required, level of performance and economic justification. Applications range from the most delicate to the most arduous and exist in almost all manufacturing industries.

Wet / Vapour Blasting – What Is It And Why Should You Consider Using It?

Wet or Vapour blasting is a mechanical method of cleaning and preparing a surface. It employs a water/ media mix, a pump together with added pressurised air. The process is widely used for a range of applications from general cleaning through to highly technical and accepted standards for industries including; aerospace, nuclear, the food industry, medical, pharmaceutical, oil and gas, utilities, powertrain, motorsport and automotive. The process is a very economical, versatile and efficient cleaning and finishing process and is used in a wide range of both general and specialised surface preparation work.
