Delay element problem
Delay element problem
(OP)
I hope this it the right subforum for this topic, forgive me if it's not. I work in in the mining detonator industry and we have a problem with our delay element. The delay composition is made out of 60% Pb3O4, 30% Si and 10% Sb2S3. This delay composition for detonators has a delay of 500ms, +-12ms tolerance. When we test the batch right out of the production, it's fine and the tolerance is indeed +-12ms. However, after 7 or more days in storage, the delay seems to fluctuate quite a lot, increasing by 20% to 30% from the original 500ms.
What could be the possible reasons behind this ? What should we look into? Our chemics can't figure it out and they're saying "it was always like this", like it isn't a problem at all.

I agree with Compositepro that it could be moisture and that if you're location is seeing different weather than 'before' research it for changes from last year and how they could affect your process this year.
