So i asked him in class.
Self healing mat how does it work.
Try flexing your cutting mat and you should see some of the old cuts open up again.
Self healing cutting mats are made from independent tiny pieces pressed together to create a solid cutting surface.
2 some of the bullet s kinetic energy is converted into heat which raises the temperature of the polymer red.
I had seen these self healing cutting mats in the micromark catalog and always wondered what they were made of.
The mats are made out of a rubber that expands slightly when cut which pushes the two sides of the cut closer together so you still have a mostly smooth surface.
Self healing materials are artificial or synthetically created substances that have the built in ability to automatically repair damages to themselves without any external diagnosis of the problem or human intervention.
1 a bullet hits the polymer gray blue and cuts a hole through it.
Better yet if it was really self healing it would re grow the corner itself like a lizard can regrow its tail the actual self healing behaviour is the same as if you were to cut on a thick rubber mat the cut is still there but the material is soft enough that the cut becomes invisible if there s nothing prying it open.
How a self healing polymer works simplified.
Self healing mats are manufactured from separate tiny pieces of material which are pressed together creating a solid surface to cut on.
He looked at me like i d grown a second head.
Add a solution of cup white vinegar per gallon of cool water and let it soak for 15 to 20 minutes.
When i was in graduate school i took a seminar class from a chemist whose work in developing self healing polymers was widely admired.
100 percent polypropylene mat can be recycled when it is used up after long term intensive use.
They expand because the inside is compressed under pressure and the film surface material is holding them in that way so when they re damaged they get released a tiny bit but are still mostly held in place by the rest of the mat.
This separates them rather than cutting into the entire unit of the surface.
Self healing mat provides a cutting surface that lasts longer than others.
When you cut on the mat using a rotary cutter the blade actually goes between the tiny pieces separating them and not cutting into the surface as a whole unit.
Warm or hot water can warp your mat.
Make sure the water is cool.
Easy to read measuring grid on both sides offers double the usage and 30 45 and 60 degree bias lines make creating triangle and star shapes easy.
What can we use self healing materials for.
3 the hot polymer flows and seals up as the bullet passes through.
To soak your mat place it in a bathtub or container that is large enough so your mat can lie flat.
