この発明は、ビヒクル等の分散媒中に、顔料粒
子等の分散質を分散させる分散装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a dispersion device for dispersing dispersoids such as pigment particles in a dispersion medium such as a vehicle.

A dispersion process in which a dispersoid made of a material that does not dissolve in each other with a dispersion medium is mixed into a liquid dispersion medium to form a dispersed state is utilized in various industries. In the paint industry as well, the process of dispersing dispersoids such as pigment particles into a suspension by dispersing them in a vehicle such as a resin solution serving as a dispersion medium has become important.
塗料製造に使用される分散装置の一例を、第３
図に示す。 An example of the dispersion equipment used for paint production is shown in Part 3.
As shown in the figure.

され、種々の工程を経て、塗料化される。 A vehicle, which is a dispersion medium 2, and pigment particles, which are a dispersoid 3, are placed in a premixer 1 and mixed,
It will be in a pre-mixed state. The mixture 4 of vehicle and pigment particles that has been premixed is sent into a container 6 of a media-type dispersion machine 5 using glass beads or the like as a medium, and is dispersed by a dispersion means 7 provided in the container 6. Begins. When it is confirmed that the dispersoid 3 is uniformly dispersed in the dispersion medium 2 and the compound 4 is in a suspended state, the dispersion is terminated. The mixture that has become a suspension is sent out from the container 5 to the next step by a pump 8, and is made into a paint through various steps.

ードバツクし、顔料粒子の分散状態を均質に管理
することが重要である。 In paint manufacturing, the dispersion state of pigment particles in the dispersion process greatly influences the quality of the produced paint, so the dispersion state of pigment particles in this process can be measured instantly online to provide feedback to the dispersion operation. It is important to uniformly control the dispersion state of pigment particles.
従来、顔料粒子の分散状態を管理するために、
次の２法が主におこなわれてきた。すなわち、分

要する。塗膜を作成する方法においては、容器中
からとり出した配合物を塗膜にするために多くの
工程と時間を必要とする。 Conventionally, in order to control the dispersion state of pigment particles,
The following two methods have been mainly used. In other words, the mixture that is being dispersed is taken out at the appropriate time to create a coating film.
There is a method of observing and measuring the physical properties of this coating film, and a method of directly observing the particle size of the taken out compound using a crush gauge or a microscope. However, in the latter method, sufficient reproducibility cannot be obtained because the observation is done visually, and the measurement requires training. In the method of creating a coating film, many steps and time are required to turn the compound taken out of the container into a coating film.
そこで、近時、この分散状態を数値化し、客観
的に評価するための種々の方法が開発されてい
る。 Therefore, recently, various methods have been developed to quantify and objectively evaluate this dispersion state.
分散状態を数値化する方法としては、例えば、
分散質粒子の分散媒中における沈降作用を応用す
る方法、分散質粒子による電磁波の散乱を測定す
る方法等がある。 For example, as a method to quantify the dispersion state,
There are methods that apply the sedimentation effect of dispersoid particles in a dispersion medium, methods that measure the scattering of electromagnetic waves by dispersoid particles, etc.
沈降作用を応用する方法は、分散質の沈降速度

電磁波の強度をもつて分散状態をあらわすことが
できる。 In the method of applying sedimentation, the state of dispersion is calculated from the relationship between the sedimentation rate of the dispersoid and its particle size, and the state of dispersion can be expressed by the settling time. A method using scattering of electromagnetic waves utilizes the fact that when electromagnetic waves such as light are irradiated onto dispersed particles, the electromagnetic waves show a scattering state depending on the size of the particles, and the scattered electromagnetic waves The dispersion state can be expressed by the intensity of .

やはり製造工程においてインラインで測定し工程
管理に用いることは難しい。 However, even in the above methods, in the method using sedimentation, a considerable amount of dilution is required to avoid interactions between pigment particles when they make a sedimentation motion, and furthermore, this dilution can cause the pigment particles to deteriorate. The dispersion state changes. In recent years, the production of paints with high appearance quality requires a very high degree of dispersion, and it is essential to use centrifugal force to promote sedimentation of pigment particles.
Even when centrifugal force is used, measurement takes time;
It is impossible to measure in-line during the manufacturing process and use it for process control. In addition, among methods that utilize electromagnetic wave scattering, methods that measure particle size using light scattering intensity distribution are used to measure particle size using a sample in which the target particle is single or has the same particle diameter and is dilute enough to prevent multiple scattering by the particles. There is a limit to the dispersoid concentration that can be used, and a considerable amount of dilution is required, which poses the problem that this dilution changes the dispersion state of the pigment particles.
After all, it is difficult to measure in-line during the manufacturing process and use it for process control.
以上のように、従来の分散状態の測定方法は、
いずれも、操作が煩雑で実用性に乏しいため、塗

All of these methods are complicated to operate and have little practicality, so in the paint dispersion process, the dispersion time is currently determined based on past experience and data. This process has become an obstacle and a problem.
