What is Concentrate 20 and what does Concentrate mean

Generally refers to the removal of solvents, including the distillation of water for concentration.

The meaning of concentration: refers to the evaporation of the solvent in the solution to increase the concentration; It generally refers to the decrease in the number of unwanted parts of the object, so that the relative content of the required parts increases.

Pinyin] [ nóng suō ].

Example sentence] Our program is a condensation of many modern social concepts. Eggplant.

Synonym. Shrink, serum, shrink, compress.

Antonyms] dilution.

Condensed almost nonsenseShrink. Pinyin] [ shōu suō ].

Explanation] (objects) change from large to small or from long to short; Deflate; Basic operations in simplex optimization; Phenomena in the production of ceramics.

synonyms] cut, attenuate, reduce, compress, shorten, interrupt, shrink.

antonyms] stretch, develop, expand, stretch, expand, develop.

Compress. Pinyin] [ yā suō ].

Explanation] (moving) Applying pressure to reduce the volume. Reduction (staff, funding, length, etc.): Expenses.

synonyms] contraction, contraction.

Antonyms] development, expansion.

Concentration refers to the evaporation of the solvent and the increase of the concentration of the solution, which generally refers to the decrease of the unwanted part and the increase of the relative content of the required part. It is mainly used in chemical industry terms.

Basic explanation. 1.One of the dewatering operations. The solvent in the solution is evaporated by heating and other methods to increase the concentration of the solution of Li-plus.

2.It generally refers to reducing the unwanted part of a thing, so that the content of the needed part is relatively increased. Such as: enriched uranium.

Qin Mu's "Discussion on the Creation of Scattered Poor Literature": "Literature requires condensation, concentration, generalization, and condensation. Ma Zhitu's "Documentary of the Study Meeting": "After I washed, filtered, and condensed it with a pen, what was left was really nothing.

3. Five sentences. ”[1]

Kinetic) refers to the evaporation of the solvent in the solution to increase the concentration. Reverse dilution. (shape) generally refers to the decrease in the unwanted part of the object, so that the relative content of the required part increases: uranium|Foodstuff.

In principle, there are two types of concentration methods: balanced concentration and unbalanced concentration.

Balanced concentration. It is a method of obtaining solute and solvent separation by taking advantage of some difference in the partition of the two phases. Evaporation concentration and freeze concentration belong to this method, in which evaporation concentration uses the difference in the volatility of solvent and solute to obtain a favorable gas-liquid equilibrium condition to achieve the purpose of separation; Freeze concentration uses the equilibrium relationship between dilute solution and solid ice at the freezing point, that is, the use of favorable liquid-solid equilibrium conditions.

Both of the above concentration methods are accomplished by the transfer of heat. Whether it is evaporation concentration or freeze concentration, the two phases are in direct contact, so it is called equilibrium concentration.

Non-equilibrium concentration.

It is the process of using solid semi-permeable membrane to separate solute and solvent, the two phases are separated by the membrane, and the separation does not rely on the direct contact of the two phases, so it is called non-equilibrium concentration, the use of semi-permeable membrane can not only separate solute and solvent, but also can separate a variety of solutes of different sizes, and the membrane concentration and disturbance resistance process is completed by Li Yuan through the pressure difference or potential difference.
