SandBlast Vs SPM-2000 English Version

 

PROBLEM
Corrosion occurs on metallic surfaces due to environmental conditions of humidity and salinity. It is necessary to keep them free from rust, to reduce maintenance costs and repair of pipes and in general any metal surface.

Currently the corrosion process is carried out in

Common metal surfaces.
Reviews surfaces which can not be subjected to sand blasting
Prefabricated parts, valves, studs and bolts
Burns surfaces welding application.
I. The process begins with a cleaning method, which can be:

a) Cleaning Sandblasting (SAND-BLAST). Where used sand blasting equipment, and skilled labor in this process. (This provided the location of the treated surface permits the use of this method).
b) Manual cleaning using pneumatic equipment, wire brushes and degreasers.

II. The next step for corrosion protection by the conventional method is the disposal of dust whether cleaning has been done by sand blasting or manual. For this step are used air compressors and / or jet of pressurized water.

III. After preparing the surface is applied RP-4 primer, applying a layer of 3 mil thickness, for which in addition to the RP-4, used a gang specialized in application, tools and equipment. Once applied RP-4, it is necessary a drying time of at least 24 hours, before continuing the procedure.

IV. The next step is the application of RA-26, for which again uses the specialized gang, minor tools and equipment, it must wait 24 hours to dry completely the link.

V. Finally apply the RA-28 finish, which is still used as the full crew of specialists and the tools and equipment, in addition to the 24 hours it will take to dry finishing with ending the process of corrosion protection, the same as be repeated again appear as oxidation.

In addition to this conventional method, I inform you of the experiences of this area with a product developed by specialists in the field. He did research on new techniques developed by experts in industrial maintenance, to find a product that meets user needs to remove corrosion from surfaces, finding an option to date is convenient for others.

This product  SPM-2000, developed by Grupo Cirro Cooper, is a polymeric rust converter, which absorbs and transforms iron oxide particles, making it a black color barrier free of moisture. Apply immediately after making a simple manual cleaning.

The application of SPM-2000 is very simple, consisting of 3 steps:

1. Manual cleaning (Light, without pneumatic equipment). The surface should only be free of oxide crusts that might be released.
2. Application of SPM-2000 two-hand brush with a curing time of 12 hours.
3. Application of RA-28 finish

III. After preparing the surface is applied RP-4 primer, applying a layer of 3 mil thickness, for which in addition to the RP-4, used a gang specialized in application, tools and equipment. Once applied RP-4, it is necessary a drying time of at least 24 hours, before continuing the procedure.

IV. The next step is the application of RA-26, for which again uses the specialized gang, minor tools and equipment, it must wait 24 hours to dry completely the link.

V. Finally apply the RA-28 finish, which is still used as the full crew of specialists and the tools and equipment, in addition to the 24 hours it will take to dry finishing with ending the process of corrosion protection, the same as be repeated again appear as oxidation.

With the use of SPM-2000 saves around 58.57 hours in the total process, which is labor-, equipment downtime during curing.

As the advantages of application of SPM-2000, polymeric rust converter, are:
• It is easily applied using only brush, roller or spray.
• Does not reduce the charter for the tube or sheet.
• saves time in the repair of surfaces requiring a coating application, because it is only necessary that the surface is free of excess layers of oxidation which may be released to the touch.
• The application of SPM-2000 saves working shifts in the prefabricated parts, and after placing studs, valves, screws because the product is applied directly to the piece.
• SPM-2000 saves over 50% of time in the assembly process of scaffolding, because the staff will only wait 12 hours to apply the finish and not 48 hours, as is done conventionally, this saves time and facilitates the relocation scaffolds to areas to protect.
• Do not use the SAND BLAST team, which equates to a saving in the transfer and management of this team that meaning risk, energy and other consumables, as well as many man-days.
• Save the application procedure of RA-26 (Link).
• It saves working shifts, by waiting for curing times.
