Might be good to have? Maybe PBTP can Help Also?

[Guest]

We might could uses these to help us HUMIDITY guys. The sample packs is not a bad deal I guess? But PBTP could get them by the truck load and get a great deal! But how do you store these dag things if you didn't have some powder to stick it in?

Help PBTP tell us how and tell us what size packet we need per pound maybe.

Duke,

If you have a semi-airtight cabnet you keep your powders in and put a pie tin full of desiccant in with the powders the desiccant will wick the moisture out of the air. We use desiccant all the time for this purpose in analyzers at work that run water samples through them but need to keep condensation away from expensive parts.

Don't want to wick to whole damn cabinet just put it in the powder container! Doing the cabinet is like buying the stuff the dummy's sell for the dummy car owners to put in their stupid car/ Dumb is Dumb You can't dehumidify the world but maybe just a tiny space Maybe.
The telephone industry has been using this before the most of you were born and what was used to keep the paper insulated telephone cable dry when you would close up the case up that the splice was in and it would get ride of all the moisture in the closure and what might have been sucked up into the cable while you had it open and then after closure the desiccant dryers from the office along with dry nitrogen bottles in the field would keep it dry so people could talk with out a problem.

Now if you take a bag saver and put your car or you powder container in it and suck out all the air and have a desiccant container in it to get what left you would be dry 100% so if you put it into a little bag or a good air tight container you win and not trying to do the whole dag cabinet. Old frig's have to breath and if not you couldn't slam the door!

Now what else do you don't need to know? I made a good living off keeping stuff dry for 30 years.

Any thing else guys?

What about the cold...its pretty freakin cold in MN come January. I'll haven't a clue what to do when that time comes around. Keeping it in the house isn't an answer, just ask the boss...

I have thought about the dessicant packs, though too. I thought they were silicone and therefore might cause a problem??

High heat and humidity are your biggest problems with powder. The cold country guys will have to tell you about cold I guess. I think your powder and where you are going to shoot works ok if all was around the same temp when using it? People like Harleydad could tell you more maybe? PBTP keeps their powder in a ambient air environment completely surrounding; encompassing their supply so it want go from one extreme to another and cause problems. Even though it does happen with some powders.

You are right about the silicone but in the packets they come in is fine. You just would not want to use it if the package got damaged. I believe that Caswell will sometimes have a packet in their powder every now and then but not sure when and for what reason they might use it and then not use it. One of the guys on the forum said he had some in his powder a while back.

I have desiccant but its in larger loose type containers and finer. I could use it for setting in side of a frig but then every time I would open the door it would take a hit.

Some shops also have the desiccant dryers tied into their air supply lines or either have a complete dryer unit.

to the shop for me for the day I guess Hope this helped you some?

We do not recommend these pac's ...

The plastic bag is barrier enough to make sure you get no lumps.
The little moisture which will penetrate throu, is at a level increasing where the shelf life of the powder is long gone.
If, of course, you decide to open the bag and let it sit like that, moisture will get in...

I would however put the _wet_ powder into the hopper and let it fluidize overnight. The dry air movement will remove all water very efficiently.

Some points to consider:

- Alone, silica gel is non-toxic, non-flammable and chemically unreactive.
However, some of the beads may be doped with a moisture indicator, such as
cobalt(II) chloride, which is toxic and may be carcinogenic. Cobalt (II) chloride is deep blue when dry (anhydrous) and pink when moist (hydrated).

- If you break a bag of silica gel by accident into the powder you will have specks and craters, big time.

- Hydrated silica gel is full of water and if you don't recharge them (Heat them to 250 F for 2 h) you have a perfect breeding ground for fungi and mould. Therfore, some packaged desiccants may include fungicide and/or pesticide poisons which are realy not healthy and may react with the powder.

When you say carcenagenic, does that mean if ingested, handled? I have that stuff in my dryer and recharge it in the oven from time to time. I'm guessing that being in the shop at that time is bad for my health...lol

I guess the solution to that would be to hold your breath
