my company does heavy abrasive blasting on steel chassis and steel dump bodies for commercial vehicles, where can i find information for heavy duty dry ice blasting???
this process is great for mold remediation,, ,, got mold damage in the house,, the price of the machine to get rid if it can cost the same as hiring someone to use the machine to get rid of it
Picking away at the substrate... this is called a profile! this is what the paint sticks too. seriously the only way it will wear away is if you continualy blast the steel after the paint is gone. even then its minimal.
@187skitzo You are an idiot. Yes paint does adhere to rough surface better than a smooth one, however just blasting away in one spot will cause your paint look like shit in that area. You will be able to see every imperfection from the blasting process hence why its just about obsolete in the automotive world. Btw I was an abrasive blaster and painter for protherm an industrial painting and blasting company so dont try and bullshit me.
@suedepolo whos the idiot, i didn't reccomend blasting the one spot for an excesssive amount of time. if you read correctly i said the only way the blasting would wear away the steel was too blast the same area continuously. who said anything about the automotive trade. there is probably a reason why your no long an abrasive blaster cuz ur a tool.
Using dry ice blasting, I assume that you still need to clean up off the floor whatever is being removed...? So if you were removing paint from a surface, you would still need to sweep up the paint particles on the floor. Correct?
@Glwillo and @Pf126p I'll aslo add to that question. I don't know anything, but after u blast the paint off do u still sand b4 primer or do u just spray primer after the blasting???
maybe a stupid question, but when dry ice is frozen CO² whats about pollution?is there any pollution?i'm sorry i don't know much about that so i'm asking.
@GIwillo It's essentially compressed CO²...take CO² out of the air, compress it, and get dry ice...no additional CO² needs to be created than what was already in the air to begin with.
Dry ice Blasting will never take the place of Abrasive Blasting. I've never seen anyone blast a hole in a good tank. Maybe where there was extensive corrosion. But the abrasive did not cut the hole. Come on!!
The primer gets a better grip with sandblasting yes, after you ice blast you need to sand the surface down abit for anything to stick or you might take a shortcut and get a nasty suprise down the road with primer and paint coming off in flakes.
we use 20/60 garnet or 30/60. depends on what type of steel you are blasting copper slag rips the shit out of softer steels. Q. with dry ice does it affect the cleaned bare steel as in contaminate it or make the steel damp etc?
The narrator says sandblasting "picks away at the substrate." In the industrial coatings field, "picking away at the substrate" is called creating a surface profile, or giving the substrate a "tooth," facilitating a mechanical bond between the substrate and the prime coat.
You need a surface profile of around 25% of the dry film thickness of the coating, which can't be achieved with dry ice.
Copper slag (Kleen Blast) is the most commonly used blast media for industrial coating.

@GIwillo I'll add to that question. What do you do about the paint that comes off? I can't imagine you can just wash it down a storm drain...

@pf126p It can be disposed of in the same manner as conventional media blasting

You don't think the factory paint had a good grip on smooth metal?
