Under what circumstances do non Newtonian liquids become solid?

Friends, you must have seen all kinds of non-Newtonian fluidsNon-Newtonian fluids, when subjected to force, become viscous and stiff enough to support a person passing through them. This is true only for that **, but it does not apply to all non-Newtonian fluids. Non-Newtonian fluids are divided into three types: bulking plastic fluids, pseudoplastic fluids and plastic fluids.

The property of bulking plastic fluids is that they become viscous and hard when subjected to force. For this part of the fluid. The way to make it thicker and harder is to apply an external force, and in layman's terms, the faster you stir, the more viscous the fluid becomes.

The opposite is true of the nature of pseudoplastic fluids, the more force they are subjected to they becomes. In fact, this kind of non-Newtonian fluid is extremely common in our lives, but because there is little related science, people almost do not notice its existence. One such example is the skincare products you use every day, they are sticky when you first apply them to your hands, but as you rub them in, they become thinner and thinner until they are invisible to the naked eye.

Plastic fluids do not flow on their own, but when a force is applied they become liquid, and it may be difficult to understand their properties alone. For example, the toothpaste we use every day is a plastic fluid, when there is no external force, even if the lid is opened and upside down and suspended, the toothpaste will not flow naturally, but once the external force is squeezed, the toothpaste will be squeezed out of the inside. <>

In fact, non-Newtonian fluids are very common in our daily life, but some ** only use bulking fluids in order to show a shocking effect, and ignore the introduction of the other two non-Newtonian fluids.

Non-Newtonian liquids are divided into three types: bulky plastic liquids, pseudoplastic liquids, and plastic liquids. Bulky plastic liquids become viscous and hard under stress; The more force applied to the pseudoplastic liquid, the thinner it becomes; Plastic liquids do not flow on their own, but they become liquids when a force is applied. So only the bulky plastic liquid becomes solid under the condition of force.

Non-Newtonian liquids are characterized by their ability to become solid when moving at high speeds or in extreme cold.

Liquids can be turned solid when moving at high speeds, or in extreme cold.

Non-Newtonian fluids, due to their own properties, become solid when they are subjected to rapid impacts.

Non-Newtonian liquids can become solid when subjected to force, and non-Newtonian liquids will have the same force "feedback" when subjected to force.

Adding more powder or lowering the temperature will turn into a solid form, and you can also choose to try other new methods that can also be changed.

Non-Newtonian fluidsIt is semi-fluid, it is not a liquid, nor is it a solid. Non-Newtonian fluids are fluids that do not satisfy Newton's experimental laws of viscosity, i.e., their shear stresses.

The fluid that is not in a linear relationship with the shear strain rate is the opposite of the Newtonian fluid. Non-Newtonian fluids include polymers.

Solutions, polymer melts, foam solutions, suspensions, emulsions, pastes and some biological fluids, etc. Flow is a movement in which the bonds are continuously deformed. A fluid is usually a substance that can be continuously deformed by any small shear force.

Newtonian fluid details

Newtonian fluid, generally refers to the fluid under any given temperature conditions, at a low or medium shear rate, its viscosity is constant, also known as true liquid. This fluid can cause a flow if it acts with the slightest force. That is to say, if the force is given, it flows, and the greater the force acting on the fluid, the greater the speed of the fluid flow, and they are proportional.

Relationship. The slope of the line is related to the viscosity of the fluid.

Semi-fluid. Non-Newtonian fluids belong to semi-fluids, which are not liquids and are not solids.

Both are fluids, and fluids are liquids.

Newtonian fluid, is a liquid.

Non-Newtonian fluids are relative to Newtonian fluids. Newtonian fluid refers to a fluid whose shear stress is proportional (linear) to the velocity gradient, that is, a fluid that conforms to Newton's law of internal friction is called a Newtonian fluid, and a non-Newtonian fluid is naturally a fluid that does not conform to Newton's law of internal friction, that is, a fluid whose shear stress and velocity gradient are not linear.

The formula is expressed as follows:

Liquid, because of the chemical reaction between its molecules and gas, so it solidifies, it is originally a liquid.

1.No non-Newtonian fluids are hard, only non-Newtonian fluids.

2.Principle of non-Newtonian fluids: Non-Newtonian fluids, when the shear forces acting on the fluid change, their viscosity changes (the viscosity of Newtonian fluids does not change).

3.The viscosity of most melts is sensitive to shear velocity, which is called non-Newtonian fluid, and the viscosity of some non-Newtonian fluids increases with the increase of shear velocity (called shear thickening phenomenon), such as plastic pastes containing thickeners, a few plastic melts with fillers, etc.

4.The viscosity of other non-Newtonian fluids decreases with increasing shear rates (known as shear thinning).

5.The reason is that when the shear force acting on the fluid changes, the microstructure of the fluid changes, so that the interaction force between the fluids changes, and the fluid particles are deformed.

According to reports, it has been reported recently that there is a way to achieve light power floating on the water in the Flying Newton Flow, and you can run directly on the water.

According to the report, non-Newtonian fluids, the surface looks no different from ordinary liquid substances, but it will show another state under special circumstances, non-Newtonian fluids refer to fluids that meet Newton's viscous experimental laws, that is, the fluid with a non-linear relationship between its shear stress and shear strain rate.

Experts say that non-Newtonian fluids are simply like water when touched lightly, and if you hit them hard, they are as hard as stones, and they themselves are a guy who eats soft and not hard. This non-Newtonian fluid is also widely found in life, production and nature.

It is reported that a few days ago, a company invented a liquid speed bump based on this non-Newtonian liquid, when the vehicle passes slowly, it will hardly feel blind and bumpy, but if it passes quickly, it will resist strongly with the vehicle like an ordinary speed bump to achieve the effect of forced deceleration.

It is hoped that related technologies can be applied to life as soon as possible.
