using calcium chloride as humidity reducer closets /laundry rooms Answered
i bought a product called "damp rid "in a hardware store that was used for removing moisture from hamper area,laundry rooms, to prevent mildew.
i realized the pelted looked familiar and it was calcium chloride.
i want to make my own as i have access to a big bag of calcium chloride.
it looks like there is a piece of tyvek/ or other moisture passing membrane on one side of the top upper half, the other 3 sides of the bag look like a mylar type bag.
The seams all seam to be sealed, except the top has a piece of plastic snapped-sea;ed over it, with a couple very small holes that go into the top half of the bag. the top plastic piece also has a hanger loop..
when i bought it the calcium chloride was in the top hang and the bottom half was empty. There looks like a plastic seam weld separating the calcium from the bottom half, and i noticed that are a couple 1/4 inch gaps in the seam.
the calcium, chloride draws the moisture out of the air and turns it into water, which falls to the bottom half of the bag.pretty cool device, and seems i t would be able to make, if i can find a source for mylar or whatever this material is. i would also have to make the seams, not sure if glue would work, maybe make a clamp like device , rather than the welds, this way i could just empty the water and replace the calcium chloride, no reason to throw it out.
anyone seen these devices, i noticed they have a www with the same name, they may have pictures. Also looking for a source for mylar and tyvek. I am not sure if the postal envelopes would work, i would also like to scrounge a sheet of tyvek to use as a ground-cloth or emergency shelter when out on my bicycle and the t storms hit.
i haven't seen it except in big rolls, i guess i should keep a lookout for construction sites trash areas.otherwise i am not sure where i could get a 10 ft piece.
i will take the bag apart later to dissect the workings and see if i can measure the thickness of the mylar
