Avoid evaporation of water with oil?




by Christophe » 28/08/08, 13:23

An idea that I recently had to avoid the evaporation of water in a volume of dead water (for example a solar buffer) not necessarily 100% waterproof: use a non-volatile liquid which would float on the surface of the water .... it is surely already done in the industrial environment but with what type of products?

We can obviously think of vegetable oil but I am afraid that the duration over time is not top ... and promotes bacterial development.

What do you think?

Ah where is the paraffin oil?
And how many mm do you think the diaper is?

It's not in paraffin drugstores?
These are pieces to melt I think.

Besides, I think my grandmother used to pour this into the jars of jam she made when I was little to keep them longer. It was a layer of a few mm.

Do not confuse paraffin oil with paraffin.
To answer Christophe's question, we find this
oil in pharmacies or among others at Fontaine-Beauvois Lodelinsart - Charleroi.

Regarding the thickness of the film, I would say from 1 to 2 mm
history that it covers the entire surface.

Very well your cutting ... It seems that your hand is greener than
me . There is nothing to say it thrives well in your garden.

In fact I just looked a little.

Both solid and liquid paraffin are chemically very similar hydrocarbons.

And from what I saw on paraffin oil, it sells in pharmacies, it is prescribed for constipation : Mrgreen:

Well, I didn't do much, I followed your registration that's all. Maybe the soil is good (it was a nettle corner -> natural nettle compost) I think the nearby stream has something to do with it too! And the summer is pretty bad too ...

Ok and thanks for the oil, I'm going to check this out for a try.

PRICE Paraffin oil (Vaseline oil, Liquid paraffin)
047.005010.60 - 1 l € 7,20 D
047.005010.74 - 5 l € 30,80 D

Shit it's downright not given ... If I need 40m² in 3mm it's 700 € ... for an uncertain result ...

It is not at all sure that this is the quick fix: in the cutting oil recovery tanks, the oil-water mixture can ferment or rot! I think that additional precautions should be taken:

- 100% mineral oil
- disinfectant
- regular water rise above 60 ° C

So be careful!
