Non-Newtonian fluid manufacturing process

The process of making non-Newtonian fluids is as follows:

Take a proper amount of starch and pour it into a container.

Gradually add water and stir into a thick paste.

After mixing starch with water, there is no separate water layer on it, which is a "non-Newtonian fluid" and cannot be inserted by hand.

Put the glass ball directly in, and the glass ball will slowly sink. When the glass ball falls freely from a height, it can be found that the glass ball that has just fallen does not directly enter, but bounces to the side first and then sinks into it.

Slowly put your fist in, just like entering the thin flour mud, but quickly hammer it down with your fist, only to find that you can't hit it at all.

Grab a handful of "mud" in it and hold it with your hands, just like holding a piece of mud. When you let go of your hand, it becomes "melted ice cream".

Non-Newtonian fluid refers to a fluid that does not satisfy Newton's experimental viscosity law, that is, the relationship between its shear stress and shear strain rate is not linear. Non-Newtonian fluids widely exist in life, production and nature. Most biological fluids are defined as non-Newtonian fluids. Many body fluids, such as lymph and cystic fluid, and "semi-fluid" similar to cytoplasm belong to non-Newtonian fluid.

Most biological fluids are defined as non-Newtonian fluids. Body fluids such as blood, lymph and cystic fluid, and "semi-fluid" similar to cytoplasm all belong to non-Newtonian fluid.

Concentrated solutions and suspensions of high molecular polymers are usually non-Newtonian fluids. The melts and solutions of polyethylene, polyacrylamide, polyvinyl chloride, nylon 6, PVS, celluloid, polyester, rubber solution, various engineering plastics and chemical fibers are all non-Newtonian fluids. Petroleum, mud, coal water slurry, ceramic pulp, paper pulp, paint, ink.

Toothpaste, regenerated silk solution, well washing fluid and completion fluid for drilling, magnetic mud, coating fluid of some photosensitive materials, foam, liquid crystal, water with high sediment concentration, debris flow and mantle are also non-Newtonian fluids.

In the food industry, tomato juice, starch liquid, egg white, apple pulp, concentrated syrup, soy sauce, jam, condensed milk, agar, potato pulp, melted chocolate, dough, rice flour balls, minced fish, minced meat and other kinds of minced food materials also belong to non-Newtonian fluids.
