I was just wondering if any of you guys knew of some Visco compositions , other than standard meal?
In patents regarding the manufacture of visco a few more formulas are mentioned:
- 30g Potassiumsilicide
70g Pb3O4
kneaded into a mixture of 15g NC and 10g dibutylphthalat
- Ordinary 70/30 KNO3/charcoal bound with nitrocellulose.
(These two are sprayed as a "liquid" into a fusebody, so these may be not of your interest.)
The following mixtures are designed to the use as relatively slow burning mixtures in visco-style fuses:
- 70parts blackpowder, 15parts KNO3, 15parts charcoal
- 40parts charcoal, 55party KNO3, 5parts sulfur
- 45parts charcoal, 55parts KNO3
Especially for waterproof coated visco, these documents mention a mixture of:
35parts charcoal
55parts KNO3
10 parts calcium fluoride
and
35parts charcoal
50parts KNO3
10parts calcium fluoride
5parts sulfur
