flyback- | I really hope you guys give long lectures daily on the dangers of HF | 03:08 |
---|---|---|
flyback- | so people are careful out there :P | 03:08 |
azonenberg | I actually have not been using HF in any of my recent work | 03:08 |
flyback- | what do you use | 03:08 |
azonenberg | Thoguh its there as i do need it sometimes | 03:08 |
azonenberg | concentration? 3% | 03:09 |
azonenberg | http://www.whink.com/index.cfm?fuseaction=cEcommerce.Product&ProductID=4328 | 03:09 |
flyback- | that is HF | 03:09 |
azonenberg | yes | 03:09 |
azonenberg | But i have not needed to etch SiO2 or Ta2O5 recently | 03:09 |
azonenberg | hence why i havent used it | 03:09 |
azonenberg | and i'm fully aware its hf http://www.whink.com/cmssites/ws0811www.whink.com/uploads/Documents/MSDS/Moonglum/Rust%20%20Stain%20Remover%2010062008.pdf | 03:09 |
flyback- | HAHAHAHAHAHAHAHA | 03:10 |
flyback- | they put Denatonium Benzoate | 03:10 |
flyback- | why | 03:10 |
flyback- | just why | 03:11 |
flyback- | by the time it's in your mouth, your teeth etc are fucked anyways | 03:11 |
azonenberg | lol, i was wondering the same myself | 03:11 |
flyback- | i'm surprised the stuff is safe enough for laundry but yet still eats silicon | 03:11 |
azonenberg | flyback-: laundry? | 03:12 |
azonenberg | its for toilet cleaning afaik | 03:12 |
azonenberg | and it doesnt eat Si, it eats SiO2 | 03:12 |
azonenberg | I think the idea is, stubborn rust stain on sink/toilet | 03:12 |
azonenberg | dissolve top micron or so of glaze on the porcelain | 03:13 |
azonenberg | take stain with it | 03:13 |
flyback- | hahaha | 03:13 |
berndj | oh is that how HF removes rust? | 11:17 |
berndj | i always assumed it was some sort of anion substitution + solubility trick | 11:18 |
B0101 | berdj: when was the last time azonenberg messaged on this channel? | 11:42 |
berndj | B0101: about 8h30m ago | 13:07 |
berndj | oops, only saw your message an hour after. make that 10 hours ago | 13:07 |
azonenberg | berndj: thats just a guess | 14:01 |
azonenberg | i could be wrong | 14:01 |
berndj | i never thought "rust remover" was something for toilets, either! i assumed it was to get rust off *metal* | 14:02 |
azonenberg | berndj: this stuff is apparently made for ceramics | 16:05 |
azonenberg | They make ones for metal too | 16:05 |
azonenberg | I have no idea, i've never used it for its intended purpose :p | 16:05 |
azonenberg | i use it as a cheap source of not-too-concentrated HF | 16:05 |
azonenberg | swkhan: did you get the wafer? | 16:05 |
berndj | what, did you send it by neutrino beam?? | 16:15 |
berndj | the only stuff i can find with "rust" in its intended purpose, seems to be based on phosphoric acid. or just "acid-based", they don't always say WHAT :( | 16:16 |
azonenberg | berndj: most of the ones meant for metal etc are phosphoric | 16:30 |
azonenberg | thats why the one HF product on the market was a lucky find | 16:31 |
flyback- | berndj, it's also nasty shit | 22:10 |
flyback- | so be careful | 22:10 |
berndj | we know by now! | 22:11 |
flyback- | well I am not taking any chances | 22:11 |
flyback- | I seen photos | 22:11 |
berndj | afaik azonenberg has calcium gluconate around Just In Case (tm) | 22:11 |
flyback- | good | 22:11 |
berndj | (maybe not calcium?) | 22:11 |
berndj | what have your dealings with HF been? | 22:12 |
Action: azonenberg uses a lab coat, norfoil gloves, goggles, and a full face shiedl as well | 22:13 | |
flyback- | none | 22:13 |
flyback- | just reading | 22:13 |
flyback- | but about 7-10 yrs ago when I was shopping at walmart and I picked up the bottle of wink | 22:13 |
flyback- | Ii yelled out "WHAT THE HELL IS THIS?" | 22:13 |
berndj | but just imagine, your bones will become birefringent as they turn to fluorspar! | 22:14 |
azonenberg | flyback-: lol | 22:14 |
flyback- | it was on the bottome shelf too | 22:16 |
flyback- | wtf | 22:16 |
flyback- | some kid could get into it | 22:16 |
azonenberg | flyback-: they put denatonium benzoate in it :p | 22:17 |
azonenberg | why??? | 22:17 |
azonenberg | by that point its already in your mouth :p | 22:17 |
flyback- | yeah by the time you tasted it you are fucked already | 22:17 |
flyback- | *CANUCKED* | 22:17 |
Last message repeated 3 time(s). | 22:18 | |
berndj | just how much of 3% HF would you need to be truly screwed? | 22:44 |
berndj | if that's less than what it takes to let the denatonium benzoate do its job, then yes, bottom shelf is bad | 22:45 |
azonenberg | berndj: i have no idea | 22:46 |
azonenberg | i've never so much as splashed a drop on me | 22:46 |
azonenberg | and i dont plan to try :p | 22:46 |
azonenberg | i've gotten a drop on my gloves once or twice but always noticed and changed immediately | 22:46 |
berndj | i got the impression that you needed a good splash for it to take (serious) effect | 22:46 |
azonenberg | berndj: Probably | 22:46 |
azonenberg | But i dont like taking chances | 22:47 |
azonenberg | gloves are cheap, fingers arent :p | 22:47 |
berndj | yeah | 22:47 |
berndj | makes you wonder how you can use fluoridated toothpaste! | 22:48 |
berndj | (i'm pretty sure by now that that "stinging" sensation from brushing your teeth is exactly what makes HF so dangerous - only in a small dose) | 22:48 |
azonenberg | No, its NaF | 22:48 |
berndj | (making little fluorspar particles in your cells) | 22:48 |
azonenberg | and in a tiny volume | 22:48 |
azonenberg | like 0.01% or so | 22:49 |
azonenberg | i dont think you ca nfeel it | 22:49 |
berndj | dunno; at the dentist you get this NaF mouthwash too, same effect | 22:49 |
azonenberg | you sure thats not the mint flavor? | 22:49 |
azonenberg | i cant stand mint | 22:49 |
azonenberg | i use this silly all-natural childrens fruit flavored toothpaste as its the only non-mint i've found anywhere lol | 22:50 |
berndj | lol | 22:50 |
azonenberg | its fluorinated but doesnt seem to have any stinging | 22:50 |
berndj | hmm, i don't know, but why would that pink dentist's solution also be mintified? | 22:51 |
azonenberg | people are used to mouth-cleaning things being mint flavored | 22:51 |
berndj | hmm, some random googling reveals "Expect to feel a tingling feeling if you use toothpaste with fluoride in it." (an article on how to cure acne with toothpaste) | 22:52 |
azonenberg | interesting | 22:58 |
azonenberg | swkhan: ping | 23:41 |
