In the coating industry, poor powder dispersion and rapid sedimentation are common challenges that can affect the quality of coatings and processing efficiency. To tackle these issues, we can focus on two aspects: equipment adjustments and powder management.
 

1. Equipment Adjustments

1.1 Adjusting Processing Parameters for Improved Physical Dispersion

By adjusting parameters of mixing equipment such as mixing speed, mixing time, and the shape of the agitator, we can enhance the physical dispersion of powders, thereby improving their mixing performance. This can effectively reduce the problem of poor powder dispersion.
 

2. Powder Management

2.1. Controlling the Impact of Moisture

It's crucial to strictly control the moisture content during the transportation and storage of powders. High humidity can lead to powder agglomeration and rapid sedimentation, affecting the processing and performance of coatings. Therefore, maintaining the powder in a dry state during transportation and storage is essential.
 

2.2. Selection of Powder Specifications

Choosing powders with the appropriate particle size is essential for addressing the issue of rapid sedimentation. Powder that is too fine tends to aggregate and form sediment in the liquid, while powder that is too coarse may affect the texture and appearance of the coating. Hence, selecting the right powder specifications based on specific application requirements and processing characteristics is important.
 

2.3. Adopting Powder Surface Treatment to Enhance Compatibility

Surface treatment of powders, such as coating or modification, can increase their compatibility with liquids, thereby reducing the problem of rapid sedimentation. This treatment promotes uniform dispersion of powders in the liquid, improving the quality and stability of coatings.

In summary, by adjusting equipment parameters and optimizing powder management, we can effectively address the issues of poor powder dispersion and rapid sedimentation in the coating industry, thus improving product quality and production efficiency.

Mesh clogging and the appearance of white spots on the surface are two common yet challenging issues in the production of rubber and plastic products. These problems not only affect product quality but also significantly reduce production efficiency. To tackle these challenges, this article provides a range of solutions from equipment adjustments to material management.
 

1. Equipment Adjustments

1.1. Enhancing Physical Dispersion

Adjusting parameters of processing machinery such as temperature, pressure, and screw speed can improve the physical dispersion of raw materials. Good dispersion helps reduce the accumulation of raw materials on the mesh, thereby alleviating mesh clogging issues.
 

2. Powder Management

2.1. Moisture Control

Controlling the moisture content of powders during transportation and storage is crucial. High humidity can cause powder agglomeration, increasing processing difficulty and potentially leading to the appearance of white spots. Therefore, ensuring powder transportation and storage under dry conditions is key to addressing this issue.
 

2.2. Particle Size Selection

Choosing the appropriate particle size of powders is essential to prevent mesh clogging and enhance product quality. Powder that is too fine may lead to rapid mesh clogging, while powder that is too coarse may affect product texture and appearance. Selecting the most suitable powder particle size based on equipment characteristics and product requirements is an effective approach to solving this problem.
 

2.3. Surface Treatment of Powders

Surface treatment of powders can increase compatibility with substrates, improve dispersion, and reduce the occurrence of white spots. Such treatment methods promote uniform distribution of powders within plastic or rubber substrates, reducing issues during processing.

By implementing the aforementioned strategies through meticulous equipment adjustments and precise material management, mesh clogging and white spot issues in rubber and plastic processing can be effectively addressed, thus enhancing product quality and production efficiency.

In the process of construction and decoration, the use of splattering and paint is an indispensable step. However, a common problem encountered during construction is the phenomenon of dripping, which not only affects aesthetics but may also reduce the effectiveness and durability of the materials.

 

1. Why Does Dripping Occur?

Dripping mainly occurs due to excessive fluidity of paint or splatter, resulting in sliding on vertical or inclined surfaces under the influence of gravity. This situation often arises when the viscosity of the material is low, and the internal structural support is insufficient to resist gravity. Dripping not only affects the appearance but may also lead to uneven coating thickness, thereby affecting its performance.
 

 

2. Recommendation to Add Talc Powder

Using talc powder is a common method to prevent dripping of paint or plaster. As a natural mineral, talc powder possesses excellent thickening and leveling properties. Its lamellar or platy microstructure can effectively absorb liquid from paint or plaster, helping to regulate its flow. Additionally, the good adsorption and dispersibility between talc powder particles can form a three-dimensional network structure in the material, which not only enhances internal cohesion but also improves resistance to flow. This structure effectively impedes particle movement, reducing material flow and dripping on vertical surfaces.

By adding an appropriate amount of talc powder, the viscosity of paint or plaster can be effectively increased, making it easier to adhere to vertical surfaces while reducing flow, effectively preventing dripping.

 

2.1. Why Choose Talc Powder? 

Enhances Viscosity and Consistency
Talc powder can increase the viscosity and consistency of the mixture, improving its resistance to gravity and effectively reducing dripping.

Improves Rheological Properties
By adjusting the amount of talc powder added, the flow properties of splattering and paint can be precisely controlled, making it easy to apply while preventing dripping.

Enhances Stability
Talc powder can form a stable suspension system in splattering and paint, reducing component separation and improving overall stability and uniformity.

 

2.2. The Importance of Talc Powder for Splattering and Paint 

Talc powder is not just a filler; it plays an important role in improving material performance, enhancing construction effects, and prolonging service life. By adjusting the particle size and dosage of talc powder, ideal viscosity and rheological characteristics can be obtained, thereby optimizing the construction effects of painting and splattering.
