VALGRO Polish is Rust resistant surface approved
For Pharma, Food, Hotel & Restaurant kitchen equipment association & Nickle institute.
|Technology||Abrasive Brush / Roller process||Abrasive belt Process|
|Surfacing benefits||Smooth clean rust free surface - Improved Ra value - easy to clean||Rough surface finish due to grinding of metal surface, cleaning is headache|
|Rust free Guarantee||Longer time Rust free Rust resistant surface||Oxide & Rust generated very fast due to wet cutting process|
|Material Loss||No metal loss just cleaning of 2B layor from surface||0.5% to 1% Material removal During the belt grinding Process|
|Heat Generation||Cool and smooth running,||Heat & Spark generation, accident chances|
|Sheet Deformation||Protect from deformation or sheet band during brushing||Sheet may band or deform due to heat generation|
|Productivity||Consistent uniform finish batch to batch or sheet to sheet||Finish may be change sheet to sheet, even same batch. Due to abrasive belt grain blunt after few working hours|
|Clogging & Cleaning||Easy to clean, No Loading, No clogging of any residue on surface||difficult to clean 100% surface after process.|

|Life of the consumables||Longer life, save time due to less maintnance||Frequent Replacement required|
Why is formation of rust possible while Belt grinding on stainless steel?
- Using the wrong process of belt grinding :
As per Europe and ANSI standard, abrasive BELT is not allow the stainless steel grinding. When grinding of stainless steel, it is possible that metal surface are more pores and grinding dust and other residue are stick on surface causes the formation of rust.
- Formation of ferretic / Pores structures during belt grinding :
Stainless steel has chemical structures which are resistant against corrosion. When grinding under high pressure. there are two effects: The surface is hurt and grooves are generated. Grooves favor the corrosion of cracks.
Due to the high pressure, the temperature increases on the working part. This might cause chemical structures which are not resistant against corrosion (pores structures). Hence formation of corrosion is possible.
- Tips for the Right handling of brushes on stainless steel :
Be sure USE THE VALGRO Nylon abrasives wire BRUSH
Be sure that there is no grinding operation on ignoble metals is the closer environment.
Do not use ANY HARD GRINDING PROCESS or ABRASIVES BELT to avoid destruction of the surface and corrosion of cracks.
The working pressure should not be too high. If possible cool while brushing.
After finishing the brushing valgro brush once more over the whole surface to clean the surface
