TYWH Calcium Carbide Production Quality Control Measures | Ensuring Product Quality and Stability

At TYWH, we understand the importance of high-quality calcium carbide for our customers' production processes. As a global leader in calcium carbide supply, we implement strict quality control measures at every stage of production to ensure both the quality and stability of our products. Here are the key quality control measures we apply during the calcium carbide production process:

Our quality of calcium carbide starts with the raw materials. We place great emphasis on the raw material selection process. First, we rigorously screen suppliers to ensure the raw materials meet quality standards and request certificates of analysis to verify the reliability and stability of the materials. Upon receiving the materials, we also conduct visual inspections to ensure they are free from impurities, ensuring only qualified materials enter the production process.

Our crushing process is critical to the final quality of calcium carbide. We use advanced crushing equipment to ensure that the raw materials are crushed evenly and stably, with the particle size meeting production requirements, ensuring that only qualified material is passed to the subsequent screening process.

Screening is a key step in determining the particle size distribution of calcium carbide. We use a multi-screen combination system to ensure the particle size compliance rate is ≥ 90%.

Iron impurities can affect the quality of calcium carbide, especially in steel production, where they may interfere with the reaction. We have installed specialized iron removal equipment on our production lines, which efficiently eliminates iron impurities from the calcium carbide, ensuring the purity of the final product and meeting our customers' stringent requirements.

To improve the cleanliness of the production environment and the quality of the product, we use a fully enclosed conveyor system. This reduces dust emission and keeps the production environment clean. The enclosed conveyor also reduces the exposure of calcium carbide to the air, slowing down the weathering process and ensuring stable gas release.

In the filling process, we use automated filling machines to reduce dust emission and improve production efficiency. The automated equipment ensures even distribution of each batch of calcium carbide, minimizing errors introduced by manual operations.

We use Siemens high-precision weighing systems to ensure that the weight error of each drum of calcium carbide remains within ±0.2KG, avoiding the impact of weighing errors on product quality and ensuring consistency in the final product.

Packaging is a critical step in the calcium carbide production process. We thoroughly inspect each empty drum to ensure there is no damage or deformation, and check the labels and markings for accuracy. The automated capping machine enhances the sealing of the drums, ensuring that the product is protected from external environmental influences during transport and storage. Additionally, we fill each packaging drum with nitrogen to remove air from the drum, reducing the exposure of calcium carbide to the air, slowing down the weathering process, and ensuring product stability.

Nitrogen filling is a key quality control measure during packaging. By filling each drum with nitrogen, we eliminate the air inside, effectively reducing the exposure of calcium carbide to the air and slowing down the weathering process. This treatment also improves the storage stability of the product, ensuring that the calcium carbide remains in optimal condition throughout global transportation.

Through these strict quality control measures, we ensure the high quality and stability of every batch of calcium carbide produced. We are committed to innovation and meticulous management to provide high-quality calcium carbide to customers worldwide, meeting the demands of acetylene production and steel manufacturing. Quality is the cornerstone of our development, and we will continue to optimize our production processes, improve product quality, promote sustainable development, and create greater value for our customers.
