Guyson Corp. has introduced a new version of its RB-RSSA-8 robotic blast system and has customized it according to the special requirements for cleaning and surface preparation of machined aerospace castings using either shot or grit media.
The new variant of the long-established model has a Fanuc Robotics LR Mate-200iD 6-axis robot mounted on the reinforced back wall of the blast chamber, a position that allows greater reach and motion capability to accommodate the range of components to be processed by the customer. In previous versions, a larger robot is mounted on a pedestal or hung from the roof of the cabinet.
A 24-inch diameter turntable is adapted to accept the component-holding fixtures for all parts to be blasted and is servomotor-driven, so the radial orientation of the component is coordinated as a seventh axis by the robot’s R-30iB controller. A jib crane mounted on the roof of the blast enclosure and a rubber-flapped crane slot facilitate loading of heavy parts onto the table, which is designed with a weight capacity of 250 pounds.

THE DRY ICE BLASTER TECHNOLOGY
| How it works|
The dry ice blasting uses small pellets of dry ice sprayed through a jet nozzle with compressed air to remove paints, oil, grease, dirt,ink, adhesives and other materials you want to remove. The frigid temperature of the dry ice against the dirty surface causes adhesion to shrink and loosen from the surface. On immediate impact, the dry ice evaporates into environmentally safe and innocuous CO2 gas.
The kinetic energy ( E = ½ mv 2)
The energy associated to the mass and to the speed is transferred to the surface to be cleaned / coating removal. This is the fundamental way to work either with this dry ice method or with sand / water etc.
When the dry ice pellets cold touch the surface, a small thermic difference occurs between the coating material, the contaminant and the substrate. This provokes cracks and the detaching facilitating the removal process.
Micro – Explosion
When the dry ice touches the surface and it transforms into innocuous CO2 gas, , this tends to invade the cracks and the pores penetrating into the coating / contaminant.Then it warms up and it expands rapidly and it makes the coating / contaminant detaching from the substrate, favouring still further the coating removal or the cleaning process.
With an inferior pressure at 5.2 bar, the solid CO2 transforms directly in gaseous state without turning into the Liquid state. But if the blasting pressure is superior at 5.2 bar ( 5.2 x 14.7 = 76.44 psi ),the CO2 in the sublimation state will show some characteristics of the Liquid CO2 while the same reaches its "triple point". Has been proved that the Liquid CO2 is a strong organic solvent so it is reasonable to suppose that this solvent action can be present when the blasting pressure is superior at 5.2 bar.

NDTV & Dettol alongwith Amitabh Bachchan have launched a mega campaign, Banega Swachh
, under the banner of CLEANATHON.
It’s a great work being done by them. India
The truth is that cleanliness in
is in a very very shocking & sad
state and the situation is really very grim. Hindustan Times in it’s news report
has just mentioned that, “ Swachh Bharat
: just 20% of the Urban waste gets treated properly“. Isn’t it shocking
& sad to know that since last 65 year’s we could not generate such
infrastructure to treat even our own urban waste, properly. The news story can
be read from the LINK. India
If we are treating just 20% of our urban waste than what’s about the rest of the 80% of the urban waste ? What’s about the rural waste ? Don’t know what our Pollution watch dog : Central Pollution Control Board is doing.
Have you seen the dirty garbage dumps at various corners of your city. These are not properly cleared and not even properly segregated for treatment. These are a major cause of pollution & responsible for various kind of diseases to the masses. But we never care for it as it has become a routine for us. We have developed a habit of CHALTA HAI & so every thing continues in it's own manner even if it's absolutely wrong.
But, thanks to National Green Tribunal that is taking real interest in it. It has just asked from all the Municipal bodies that why they are failing to enforce the guidelines of the Municipal Solid Wastes ( Management and Handling) Rules, 2000 that provides for proper segregation and disposal of the waste generated in cities.
This clearly shows that how much work is still to be done for making
a Cleaner India. NDTV &
Dettol are doing a great job. It will cover around 400 villages across 8
states. More details of CLEANATHON can be viewed from their website : http://swachhindia.ndtv.com/ India
But much more is required to be done to safeguard our motherland from the health point of view. We must join this campaign. We must come forward to clean our homes, our localities & our cities. It will result into a Swachh home, a swachh street, a swachh locality, a swachh town, a swachh city and than a swachh
. We can also make Donations for this great cause. India
We must teach the masses to use Dettol for the cleanliness & hygiene. If we are not willing to do it even now, just think what will happen to our ENVIRONMENT. Probably that’s the reason that we are already on the verge of a Cancer disaster & if not taken seriously, don’t know what more will be happening in our
NDTV & Dettol alongwith a Great Brand Ambassador Sh Amitabh Bachchan can play a much wider role to make
a cleaner one. NDTV has a very
wider reach directly in the homes & hearts of masses. Similarly, Dettol is
a well known, very popular brand making India a hygienic one. This combination
alongwith Amitabh Bachchan can do miracles in India . If we too join them, no doubt our India will soon become a Swachh India - Banega Swachh India. Therefore, we must Join CLEANATHON on the 14th December, 2014. India
