- the temperature at which ⁇ ' ⁇ ⁇ '. ',! Is preferably 30 to 100 ° C. If the temperature is lower than 30 ° C., sufficient viscosity is unlikely to occur, and if the temperature is lower than 100 ° C., the composition of the dispersion medium may change due to evaporation of the dispersion medium.
- a temperature of 40 to 80 ° C. is particularly preferable because the viscosity I ′ is sufficiently generated and the change in convergence is small.
- the energy applied to the dispersion ⁇ is 0.011 to 10 kWh per Knl kg of the dispersion ⁇ . It is preferable that The energy--added to the dispersion A can be expressed in power (kWh) X processing time (h) Z in K (kg) of the dispersion to be processed. If the energy is less than 0.01 kWh, the viscosity may not be sufficiently high. If it is more than 1 O kWh, the viscosity may be extremely increased. 0.05 to ⁇ k and Vh are preferable because the viscosity I: is also moderate and easy to control.
- the output of the ultrasonic wave is preferably 30 to 2000 W. If the output is less than 30 W, the external force applied to the dispersion liquid ⁇ ⁇ ⁇ is small, so that it may take time to increase the viscosity to I: H or the viscosity may not be sufficiently increased. On the other hand, if the output is more than 2000 W, the applied external force will be too hot and the viscosity will increase rapidly, and the heat will increase and the composition of the dispersion medium may change significantly, making it difficult to control. An output of 300 to 900 W is preferable because the viscosity is moderate and heat generation is controlled.
- the tip of the chip is the liquid to be treated: t U, but preferably 5 to 50 mm ⁇ . If it is smaller than 5 ⁇ , the amount of liquid that can be processed at once is small and it is not efficient. Even if the diameter is larger than 50 mm ⁇ , the efficiency will not increase much just because the tip becomes expensive. In addition, when the separation between the tip and the liquid is fierce, the applied energy is significantly reduced when the separation is fierce. Therefore, a narrow vessel for picking up the chips is used, and the liquid circulates there or diminishes several times. It is preferable to perform a uniform treatment by distributing.

- Energy applied to the dispersion ⁇ by shearing is preferably a child and per kg 0 3 ⁇ 1 0 8 J shear rate [dispersion ⁇ of ⁇ position K in terms of the set to] ⁇ Ikihan of h predicate . And said energy] 0 3 J smaller, dispersion viscosity is sufficiently in A I: There may not be ', also, 1 0 K and fire heard from J, there may cause personal viscosity too above undesirable. When the energy is at 1 0 4 ⁇ 1 0 7 J, since it controls replication pyramid also moderate on the viscosity preferred. Even if the shear rate is smaller than the above range H, the energy applied to the dispersion liquid can be reduced by reducing the residence time. It can be ignited, but no matter how much shear is applied at low shear rates, the viscosity of the dispersion does not decrease.
- the shear force is applied by the speed Mfe.
- the Mfe number of 3 ⁇ 4 ⁇ is preferably 100 to 50,000 rpm.
- the number is lower than 1000 rpm, sufficient external force is not applied to the dispersion, the viscosity is not sufficiently increased, and as a result, the strength of the cast crotch may not be reduced.
- the number is more than 500 rpm, the applied external force is too high, the viscosity is sharply increased, and the ultimate heat is increased, so that the composition of the dispersion medium may be greatly changed.
- the Mfc number is from 300 to 300 rpm, the viscosity is appropriately increased over time, and the heat generation is preferably small.
- a shear force is applied by a homogenizer or a homomixer.
- 3 ⁇ 4A has a non-uniform liquid along with the viscosity of II ⁇ H. Therefore, it is preferable that the entire liquid be kept at a low level at M.
- the grinder material K carbon carbide alumina which is easily sheared even with soft K material.
- the clearance of the grinder is preferably 0 to 80 / m. If the clearance is smaller than 0 / i iri, too much shearing force is applied and heat generation becomes intense, making it difficult to control. If it is more than 80 mm, it is difficult to apply shearing force and the viscosity may be insufficient. is there.
- the crusher it is also possible to obtain a tree dispersion liquid by circulating or flowing several M.
- the viscosity of the dispersion at the viscosity step at 25 t: shear rate ⁇ 0 (1 / s) is increased by 2 to 200 times ⁇ ⁇ ⁇ ⁇ in the sticking step. That is, the viscosity of the dispersion B is 2 to 2000 times the viscosity of the dispersion. If the viscosity is less than twice, the effect on the viscosity will not be fired, and the strength of the crotch obtained by making the dispersion liquid will not be sufficient. If it is fired more than 2000 times, the viscosity will be too high, and the crotch will be difficult.
- the viscosity of the dispersion liquid is preferably the same as that of the dispersion liquid.
- the city version of Nafion solution (made by Aldrich) is a dispersion in which a fluorinated polymer containing sulfonic acid ⁇ is dispersed in water and alcohol, and the concentration of the W-form is in contrast to the dispersion ⁇ .
- the ratio is 5%, but the viscosity at 25 ° [;, shear rate 10 (IZS) is 1 OmP a ⁇ s.

- These alcohols may be rivers in Germany or two or more times.
- water or another dispersion medium may be used as the dispersion medium to flow.
- the other dispersion medium is not particularly limited, and for example, the following ones can be used.
- Perfluorotributylamine, perfluoro-21 -n-butyltetrahydrochloride Perfluoro-containing or compound containing furan, such as furan, 1,1,2-trik U II-1,2,2- Fluorocarbons such as trifluorofluoroethane, etc., 3,3-Dichloro-1,1,1,2,2-Pennofluoropropane, 1,3-Dichloro-1,1,2,2,3 —In addition to hydrofluoric acid fluorocarbons such as pentafluoropropane, N, N-dimethylformamide, N, N-dimethylacetamide, dimethylsulfoxide, water and other pesticides can be used.
- dispersion media may be used alone or in combination of two or more.
- a dispersion liquid in which a polymer containing a sulfonic acid-containing fluorinated compound is dispersed in a dispersion medium a polymer that is not uniformly dispersed may leave a small amount. This is because it is preferable to remove them.
- 1 ⁇ ) Filtration after ⁇ is possible for viscosities, but ⁇ ) Viscosity of the liquid is h This is not preferable because the efficiency of the method significantly decreases.
- the hole of the fil-yu-ichi which flows into the river is preferably 0.5 ⁇ 30 / m. If it is smaller than 0.5 in, the filtration efficiency is reduced, and if it is larger than 30 m, uneven coagulates are not sufficiently filtered off, which is not preferable.
- concentration adjustment: 1: 3 ⁇ 4 for adjusting the concentration of the ion exchanger polymer in the liquid may be performed before the viscosity.
- the concentration of the dispersion in the dispersion at the time of the transition to the viscosity is 3 to 40% of the dispersion ⁇ K). If the concentration of the form 1 is less than 3%, the ultrasonic wave does not have sufficient hW of the viscosity of the liquid due to the application of shear force, and the strength of the crotch formed by forming the obtained dispersion B is insufficient. It may be insufficient. -If the force and the concentration of the W-shaped component are more than 40%, the viscosity of the liquid in the thigh becomes extremely V-, and it may be difficult to prepare and disperse with the dispersion B, which is 30%. It is more preferable that the number is as follows.
- the ultrasonic wave is moderately on the upper surface of the liquid skin due to the application of shear force, and can be obtained by forming the obtained dispersion. It is particularly preferable because the crotch strength and the productivity are good.
