In the production process of iron oxide black, what advanced process equipment does Deqing Demi Pigment Technology Co., Ltd. use to improve production efficiency and quality?

1. Advanced raw material processing and reaction process
The production of iron oxide black is usually achieved by chemical synthesis, and the pretreatment of raw materials is crucial in this process. The production process of Deqing Demi Pigment Technology Co., Ltd. first realizes refined management in the selection and processing of raw materials. The company uses advanced automation equipment to accurately proportion and automatically put in raw materials to ensure that the proportion of each batch of raw materials is accurate. This precise raw material processing technology can ensure the stability of the reaction process and effectively avoid color difference or unstable performance caused by uneven raw materials.

In the reaction process, Deqing Demi Pigment uses high-efficiency reactors and continuous reaction systems. These equipment can achieve full reaction of raw materials and reactants through precise temperature and pressure control, avoiding inefficient production caused by incomplete reaction. In addition, the reactor is equipped with an intelligent monitoring system that can monitor the reaction temperature, pressure and pH value in real time to ensure stable reaction process and consistent product quality.

2. Refined pulverization and dispersion process
The particle size and distribution of iron oxide black pigment are crucial to its color, durability and stability. Deqing Demi Pigment uses efficient ultrafine pulverizers and dispersion equipment in the pulverization and dispersion process.

The company introduced airflow pulverizers and high-energy dispersers, which can grind the pigment powder to the required micron level during the production process, and avoid the agglomeration of pigment particles through special dispersion technology. The airflow pulverizer uses high-speed airflow to collide the raw material particles at high speed to achieve the ultimate refinement effect, while the high-energy disperser can evenly disperse the pigment particles in the solution, avoiding the problem of particle sedimentation and uneven distribution. This not only improves the color uniformity of the product, but also significantly improves its coverage and gloss.

3. Efficient drying and dehydration technology
In the production process of iron oxide black, the removal of water is an important link, especially for the production of high-performance pigments. The efficiency of dehydration technology directly affects the drying speed of the pigment and the final color effect. Deqing Demi Pigment introduced spray drying towers and vacuum dehydration equipment in this link.

The spray drying tower can achieve rapid drying of raw material particles while maintaining the uniformity and morphology of the particles. By controlling the temperature and spray pressure, the spray drying tower can completely evaporate the water in the pigment slurry in a short time, avoiding the degradation of pigment performance caused by too long heating. In addition, the vacuum dehydration equipment can further remove trace moisture in the pigment to ensure that the final iron oxide black product reaches the highest purity and color.

4. Automated quality inspection and control system
In order to ensure the high quality of iron oxide black pigment, Deqing Demi Pigment introduced a fully automated quality monitoring system in the production process. The company is equipped with a variety of advanced testing equipment in the production line, including laser particle size analyzer, colorimeter, microscope, etc.

The laser particle size analyzer can monitor the particle size distribution of iron oxide black pigment in real time to ensure that the fineness and particle size of the product meet the specification requirements. The colorimeter ensures the color consistency of each batch of products in the production process by accurately measuring the color of the pigment. The microscope is used to observe the surface morphology of the pigment particles and detect whether there is agglomeration or irregular particles to ensure the high dispersion and uniformity of the product.

All test data are uploaded to the central control system in real time, and technicians can adjust production parameters according to the data to ensure that the pigments achieve the best quality in every link.

5. Efficient post-processing and surface modification technology
Deqing Demi Pigment also uses advanced surface treatment technology in the production process of iron oxide black to improve the stability and weather resistance of the pigment. The company introduces silicone surface treatment and inorganic coating technology to modify the surface of iron oxide black particles, making them more resistant to UV rays, oxidation and high temperature.

Through this surface modification technology, iron oxide black pigments not only have stronger durability, but also can maintain their excellent color performance and stability under different environmental conditions. When used outdoors or in high temperature environments, the surface-modified iron oxide black pigments can effectively prevent color fading and performance degradation, ensuring long-term application effects.

6. Intelligent production scheduling and management system
In order to further improve production efficiency, Deqing Demi Pigment has also introduced an intelligent production scheduling system. By integrating big data and cloud computing technology, the system can analyze the working status of the production line in real time, automatically optimize production scheduling, and reduce unnecessary waiting time and equipment idle time during the production process.

The intelligent system can also predict the maintenance cycle of the equipment, perform preventive maintenance in advance, and avoid the impact of equipment failure on production progress. The system is also connected to the quality inspection equipment and can adjust the parameters in the production process in real time to ensure that each batch of iron oxide black pigment meets high quality requirements.

7. Environmental protection and energy-saving technology
During the production process, Deqing Demi Pigment pays attention to environmental protection and energy saving, and adopts a number of green environmental protection technologies. The company effectively reduces the emission of harmful gases through waste gas treatment facilities, and uses the waste heat recovery system to recover the heat energy generated during the production process for heating and drying processes, further improving energy efficiency.

The water and chemical reagents used in the production process are also strictly recycled and treated to ensure harmless emissions and meet national environmental protection standards.
