As an important functional filler in coatings, the transparency of talcum powder directly affects the visual effect and optical performance of the coating. This article systematically analyzes the influence mechanism of talcum powder transparency, key determining factors (such as purity, particle size, morphology), and their specific effects on coating coverage, gloss, and color presentation.

Entering Midsummer：The sound of the Loong Boat race with gongs and drums is gradually spreading around the streets.

In order to thoroughly implement the important speech of General Secretary Xi Jinping at the symposium on promoting the comprehensive revitalization of Northeast China in the new era, on April 22, the Secretary of the Haicheng Youth League Municipal Committee led a team to conduct research work at Liaoning Xinda Talc Group.

This study focuses on the key technical bottleneck of regulating the diameter to thickness ratio of talc powder, and systematically explores the preparation mechanism of coarse-grained large diameter to thickness ratio talc powder based on interlayer van der Waals force failure. By comparing the energy efficiency, diameter to thickness ratio, and industrialization cost of traditional airflow grinding/steam grinding processes with new interlayer stripping technologies, the limitations of existing processes in China were revealed. 

On April 12, 2025, Liaoning Xinda Talc Group received a delegation of Indian customers, and the two sides conducted in-depth investigations and consultations on the cooperation of the entire talc industry chain. 

On April 18th, CCTV's attention focused on the smart factory of Liaoning Xinda Talc Group. Xinda showcased the industry's new heights of "smart manufacturing" with its leading intelligent manufacturing practices.

Established in 1995, it is the earliest talc enterprise in China to develop and research in the field of talc deep processing, and is known as the "enterprise with the longest talc deep processing industry chain in China"

One of the characteristics of powder is particle size distribution. What is particle size distribution? This concept and its application development originated from the mining industry, where ores undergo various beneficiation processes after crushing. Therefore, the shape and size of particles have a significant impact on beneficiation processes and equipment.

We often hear about 1250 mesh, 800 mesh, and 400 mesh talc powder in the powder industry. So, what is the unit of measurement for this' mesh '? Is it appropriate to use it to describe the fineness of the powder? This article will trace back to this concept and its corresponding models.
