Hi All , Much appreciate your answers/help. The cylinder is about 7cm in length and 2cm wide. The container itself is made of ABS/PP plastic , wall thickness about 1mm so pretty strong. Inside of the cylinder there compacted powder , leaving a gap of around 0.5mm all around the powder (in order...

Hi LittleInch , I am sorry to be vague. Essentially I am talking about a very small cylinder with active ingredients which only form a reaction once water is added. The amount of water required is not much but needs to be contained separately from the other ingredients inside the cylinder. The...

Hi All , I am looking to release a few ml of water inside a sealed cylinder. Basically the water is contained in a small chamber (or capsule or cartridge etc) and needs to be released from the outside of the cylinder without opening the cylinder (as liquid may then come out) I am looking for...

Thank you IRstuff , this is a big help. I wil post updates soon.

Again , I am looking to prevent the zncl2 reacting with steel by means of a conductive barrier coating , I think I have passed the basic battery chemistry lessons. Zinc acts as an anode in a conventional zinc-carbon battery and does not use a steel can for conductivity. I am looking for insight...

Well , the idea is a new technology we are working on. Other chemistry batteries do not have the issue of zncl2 , in our research we are bound by zncl2 for other reasons. Graphite does protect the steel but trying apply it to the inside of a can is still a challenge.

Working on a battery with a steel casing. Steel casing is lined with graphite paint but the zncl2 inside the battery still reacts with the steel. Does Ag react with ZnCl2 ? is there a way to coat Pure graphite on steel (enough to prevent the reaction with ZnCl2) I have tried to use 0.02mm pure...
