The gel in the finish from the ink column is known as as ‘stopper fluid’.
Essentially gel pen’s ink is really a suspension of colour particles inside a water gel,unlike the dye-alcohol factor in ballpoint pens. This thick and opaque gel-based ink can leak in the backside from the refill. Here comes the saviour-the stopper fluid. It is a thick gel that keeps a lot of it from dripping out. It is just like a plug. Consider vacuum pressure seal,or perhaps a syringe,and you’ll get to know.
This fluid can evaporate. So when it will,a lot of it flows out. (Not under only disaster)
I am unsure what it really consists of,but appears like silicone,or silicone and several drying agent. NOT verified though.
It’s really plastic gel . It really is useful . How should you ask ?
It functions like a barrier between your ink within the refill and also the atmosphere outdoors the refill.
Additionally, it functions like a weight around the ink to match smooth flow of ink .
Lastly , it may also help prevent leaks . First of all , it doesn’t allow leaks to occur because it is firmly make the refill .
Hope this can help.
The gel in the finish from the ink column inside a tube is known as as ‘folower’. It is a kind of grease which is often used to prevent the evaporation water based inks and occasional viscosity inks. As these water inks can evaporate there the folower can be used to prevent evaporating. Once this is done it instantly functions like a stopper if a lot of it might have leaked but which was already avoided. Ball pens don’t have the folower inside them because they are oil based and don’t evaporate.
Therefore regarding popular thought that the ‘gel’ can be used to stop the leakage of ink but rather it’s mainly employed for stopping a lot of it from evaporating.
The obvious fluid is known as a lot of it FOLLOWER
The gel is really a suspension of pigment particles within an aqueous solution of the polymer. The gel should have the perfect qualities – it needs to be thick enough to suspend the pigment particles but thin enough to circulate to the ball and so the paper. In fact many polymer solutions are shear thinning, and also, since suspending the pigment is low shear while flowing to the ball is high shear just one polymer can meet both needs.
However utilizing a shear thinning polymer entails that in high stress situations, e.g. shedding the pen to the floor, the gel could shear thin and flow from the finish from the tube and make up a mess. Adding a plug of ink follower prevents this. A lot of it follower doesn’t have to circulate to the ball and paper also it does not need to suspend oxide particles, so it may be selected exclusively for being able to resist sudden shocks like shedding the pen.
Ink supporters are usually low volatility oils of numerous types thickened having a solid for example silica or clay. Being non-polar ensures they don’t mix using the gel, and in addition it prevents evaporation from the gel
