What is the pigment dispersion method?
The pigment dispersion method refers to the process of suspending insoluble pigments in a liquid medium, such as water or organic solvent, in order to make them usable in inks, paints, and coatings. This method typically involves three main steps: wetting, deagglomeration, and stabilization.
- Wetting: In this step, the pigment particles are mixed with the liquid medium to ensure that they are thoroughly wetted and dispersed. This can be achieved through mechanical agitation or the use of dispersing agents that help break down the surface tension and promote uniform wetting.
- Deagglomeration: Pigment particles often have a tendency to form agglomerates or clusters, which need to be broken down to achieve a more uniform dispersion. This step involves mechanical techniques, such as milling or grinding, to reduce the size of the agglomerates and disperse the individual pigment particles.
- Stabilization: After deagglomeration, it is important to prevent the re-agglomeration of the dispersed pigment particles. Stabilization is achieved by adding suitable additives, such as dispersing agents, surfactants, or rheology modifiers, which help maintain the stability and prevent settling or flocculation of the pigment particles.
The pigment dispersion method is crucial in ensuring that pigments are evenly distributed and efficiently utilized in various applications, allowing for the creation of vibrant and durable colors in inks, paints, and coatings.
How do you disperse pigment in oil?
To disperse pigment in oil, particularly castor oil, a two- or three-roll mill can be used in a batch process. Here are the general steps involved:
- Preparing the pigment: Ensure that the pigment is properly pre-dispersed or pre-ground to minimize the particle size and agglomeration. This can be done by using a suitable grinding or milling technique.
- Weighing and mixing: Measure the desired amount of pigment and the oil (castor oil) in the appropriate ratios based on the desired pigment loading. It is important to accurately measure both the pigment and oil to achieve consistent results.
- Dispersion on a mill: Place the mixture of pigment and oil onto the mill, which consists of two or three rotating rollers. The mill applies mechanical force and shear to the mixture, effectively breaking down the pigment agglomerates and dispersing them into the oil.
- Adjusting parameters: Control the speed and gap between the rollers to optimize the dispersion process. Higher shear forces can be achieved by reducing the gap between the rollers or increasing the speed. It is important to find the right balance to ensure efficient dispersion without damaging the pigments or overworking the mixture.
- Multiple passes: Depending on the desired level of dispersion, it may be necessary to pass the mixture through the mill multiple times. Each pass further reduces particle size and improves dispersion.
- Evaluating dispersion quality: Regularly check the dispersion quality during the process. This can be done visually or through laboratory tests, such as measuring particle size distribution or using color measurements.
It is worth noting that the specific details of the dispersion process may vary depending on the equipment used, the properties of the pigment and oil, and the desired outcome. Adjustments and modifications may be necessary based on the specific requirements and characteristics of the materials being dispersed.
Does Meizu still exist?
Yes, Meizu still exists as a smartphone manufacturer. As of my knowledge, Meizu Technology Co., Ltd. is still an active company. It was the 11th largest smartphone manufacturer in the world in the past and sold a significant number of units. In 2015, Alibaba invested a substantial amount in Meizu, acquiring a minority stake. Additionally, in June 2022, Geely acquired a majority stake in the company. However, it’s worth noting that the current status and operations of the company may be subject to change, and it’s always recommended to verify the latest information from reliable sources.
What OS does Meizu use?
Meizu smartphones use the Flyme OS as their operating system. The specific version mentioned in the provided information is Flyme 10.0 OS, which is based on Android 13. Meizu’s 20 Series devices are powered by the Snapdragon 8 Gen 2 processor and run on Flyme 10.0 OS. The Flyme OS is known for its unique design and features, and it is supported by Meizu’s proprietary software language called Alive Design.
