(Industrial Application Field) The present invention relates to an emulsification device. More specifically, the present invention relates to an emulsification device that produces an oil-in-water emulsion using a liquid emulsified material and a surfactant. (Prior art and problems) Conventionally, emulsification is carried out using ordinary emulsifying devices such as homomixers, homogenizers, and colloid mills, but when the concentration of the emulsified liquid is very low, it is difficult to control uniformity. It was also expensive and difficult to emulsify effectively. (Means for solving the problem) In view of the above circumstances, the inventors of the present invention have conducted various studies and have devised an emulsifying device that is cheaper than conventional ones and can effectively produce a dilute emulsion. It came to this. That is, as shown in FIG. 1, in a method using a liquid to be emulsified and a surfactant, the inner diameter of the emulsifying pipe 1 is 20 to 60 mm, and the straight pipe portion 2 to 5 times the length of the inner diameter is 4, one each of stirring water injection nozzles 5 to 7 having a nozzle diameter of 1/100 to 1/20 of the inner diameter of the pipe are provided for each straight pipe part, and the water injection nozzle 5 to 7 so that the injection direction coincides with the central downstream direction along the flow path, and the mixed liquid of the liquid to be emulsified and the surfactant is placed immediately after the first water injection nozzle 5 and in the center of the pipe. An emulsifying device characterized in that it is equipped with a means 8 for supplying . (Function) According to this emulsifying device, the jet flow from the first water jet nozzle 5 installed in the center of the piping with a limited inner diameter creates a turbulent flow (the jet flow flows outward against the jet flow from the central nozzle). A directional flow occurs, causing turbulence between the center and the outside), and a stirring force is generated. Further, by additionally providing a second stage nozzle, stirring power can be added. In this manner, the emulsified material (sizing agent) is gradually atomized by the jet streams from a plurality of nozzles, and the degree of dilution is increased, so that it can be dispersed extremely efficiently to the desired particle size. Therefore, by using the emulsifying device according to the present invention, it is possible to easily adjust the stirring force by simply controlling the water pressure of the water jet nozzle, and furthermore, it is possible to make the emulsified liquid into the optimum particle size distribution. It is possible to express it effectively depending on the purpose of use. (Example) Since the emulsifying device of the present invention is particularly effective in producing a sizing agent for paper manufacturing, an example will be described in detail below regarding emulsification of a sizing agent, but the present invention is not limited thereto. It can be widely applied to oil droplet emulsification. Usually, when used as an oil-in-water emulsion, the concentration of the liquid sizing agent is about 0.02 to 2%, and the concentration of the surfactant is 0.5 to 20% of the liquid sizing agent. The agent
The concentration will be 0.0001-0.4%. In order to generate a stable emulsion with such a small amount of surfactant, it is important to adjust the stirring force as described above to make the liquid sizing agent have an optimal particle size distribution and to effectively express the size effect. It is. In other words, if the particle size distribution is too large, the liquid sizing agent will separate and float on top of the water in the form of a film, and if the particle size distribution is too fine, the area of the interface will become too large, causing the interface Even if the active agent forms a monomolecular film, it will be difficult to maintain the formation, resulting in poor stability and reduced size effect. It is important to express it effectively. In addition, for emulsifying piping specified in the claims of the present invention whose inner diameter is 20 to 60 mm and which has multiple straight pipe sections with a length of 5 times or more the inner diameter, first, stirring is required if the inner diameter is less than 20 mm. It is difficult to provide a water injection nozzle inside, and if the diameter exceeds 60 mm, the stirring effect will deteriorate. In addition, if the length of the straight pipe part is not at least 5 times the inner diameter, the injected water will collide with the wall of the emulsification pipe and the stirring effect will deteriorate. In addition, the diameter of the water injection nozzle for stirring is preferably 1/100 to 1/20 of the inner diameter of the emulsification pipe.
As for the number, it is preferable to provide a plurality of them in order to widen the range of control. Examples of the liquid sizing agent used in the present invention include alkyl or alkenyl succinic anhydride. (Effects of the invention) Next, specific examples of the invention are shown in the table below.
