People's Daily Focus | Hezhou Strengthens and Expands the Calcium Carbonate Industry

From being ignored to becoming an industrial "treasure trove", from mining and producing stone materials to forming a complete industrial chain covering upstream and downstream, in recent years, Hezhou, Guangxi has taken multiple measures to promote the calcium carbonate industry for stone materials to grow stronger. Data shows that in 2022, the output value of Hezhou's calcium carbonate industry exceeded 35 billion yuan, providing over 40,000 jobs locally.

The uses of ultrafine calcium carbonate powder.

Ultrafine calcium carbonate powder, also known as ultrafine heavy calcium carbonate powder, is a fine particle inorganic compound powder with a wide range of applications. Here are some common application areas for ultrafine calcium carbonate powder.

The specific applications of ultrafine calcium carbonate in industry include: 1. **Plastics**: Used as a filler to improve the mechanical properties and reduce production costs of plastic products. 2. **Paper**: Acts as a filler and coating pigment to enhance brightness, opacity, and printability of paper products. 3. **Paints and Coatings**: Serves as a pigment and filler to improve the texture, durability, and finish of paints and coatings. 4. **Rubber**: Utilized as a reinforcing agent to enhance the strength and durability of rubber products. 5. **Food Industry**: Used as a food additive for calcium fortification and as an anti-caking agent. 6. **Pharmaceuticals**: Acts as an excipient in the formulation of tablets and other dosage forms. 7. **Cosmetics**: Employed as a thickening agent and filler in various cosmetic products. 8. **Construction Materials**: Used in the production of cement and concrete to improve properties and reduce costs.

Ultrafine calcium carbonate has a wide range of applications in industry. Below, we will provide a detailed introduction to its specific applications. Ultrafine calcium carbonate, due to its high whiteness, can serve as a framework in products, enhance the hardness of the products, and improve the surface gloss and smoothness. It can also replace expensive white pigments.

Heavy calcium carbonate and active calcium carbonate have several differences: 1. **Production Process**: Heavy calcium carbonate is produced by crushing and grinding natural limestone, while active calcium carbonate is produced through a process that involves calcination and hydration, making it more reactive. 2. **Chemical Composition**: Both are primarily composed of calcium carbonate (CaCO3), but active calcium carbonate has a higher surface area and is often treated to enhance its reactivity. 3. **Applications**: Heavy calcium carbonate is commonly used as a filler in products like plastics, rubber, and paints, while active calcium carbonate is used in applications that require higher reactivity, such as in the production of calcium oxide or in certain chemical processes. 4. **Physical Properties**: Heavy calcium carbonate tends to have a larger particle size and is denser, whereas active calcium carbonate has finer particles and a higher specific surface area, which contributes to its reactivity. 5. **Cost**: Generally, active calcium carbonate is more expensive to produce due to the additional processing steps involved.

Both heavy calcium carbonate and active calcium carbonate have wide applications in industry. So how can we distinguish between heavy calcium carbonate and active calcium carbonate? What are their differences? Heavy calcium carbonate, abbreviated as heavy calcium, is produced by directly grinding the ore using machines. No additives are added; it is simply ground by machines. Therefore, it is called heavy calcium carbonate.

Hezhou City will build a green high-end calcium carbonate transportation corridor.

Recently, the Hezhou City Transportation Construction Development Center held a preliminary work coordination meeting for the Hezhou Green High-end Calcium Carbonate Transportation Corridor PPP project, aiming to accelerate the construction of new multimodal transport corridors in Hezhou to adapt to the rapid development of the green high-end calcium carbonate industry cluster.

Strategies and Suggestions for High-Quality and Healthy Development of the Calcium Carbonate Industry

We have previously discussed some issues and the basic situation of the calcium carbonate industry. Now, in response to the problems of extensive utilization, high quality but low usage, and the shortage of the industrial chain in the domestic calcium carbonate resource utilization, we propose some development strategies and suggestions. The basic approach includes five aspects: mine integration, green mining, the principle of tiered utilization, optimization of allocation, and coordinated development of industrial parks. This provides a systematic and detailed description of the methods and principles for the tiered high-value and efficient utilization of the calcium carbonate industry, offering important support for the establishment of targeted specific principles and policies for the high-quality and efficient utilization of mineral resources in our country.

Hezhou City held a press conference on the development of the calcium carbonate stone industry.

On December 21, Hezhou City held a press conference on the development of the calcium carbonate stone industry, reporting on the current status of the calcium carbonate stone industry in Hezhou and answering questions from reporters. Currently, the calcium carbonate stone industry in Hezhou has shown a trend of multi-point blossoming and cluster development, becoming the main driving force for leading the high-quality industrial development of Hezhou and a key player in accelerating the economic and social development of Hezhou.

The difference between light calcium and heavy calcium in the application of plastics and rubber.

We often add calcium carbonate to prepare low-cost products or to enhance certain properties. The main types of calcium carbonate used in the plastics field are heavy calcium carbonate and light calcium carbonate. Although heavy calcium carbonate and light calcium carbonate have the same chemical formula and similar appearance, there are significant differences in their physical and chemical properties as well as their processing methods.
