Industry knowledge

As one of the major acid anthraquinone dye manufacturers in China, how does Tianya ensure that the quality control of its products meets international standards when producing 2-Amino-5-chlorobenzotrifluoride?

1. Raw material procurement and inspection
Selected raw materials: Tianya always insists on selecting high-quality raw materials in the raw material procurement process. The raw materials required for the production of 2-Amino-5-chlorobenzotrifluoride, such as m-chlorotrifluorotoluene, mixed acid (30% HNO3 and 70% H2SO4), iron powder, etc., are purchased from well-known domestic and foreign suppliers and undergo strict screening and testing to ensure the purity and stability of the raw materials.
Raw material inspection: All purchased raw materials must undergo a strict inspection procedure before entering the production line. This includes appearance inspection, purity determination, moisture content detection, etc. to ensure that the raw materials meet production requirements. Tianya has also established a raw material quality traceability system that can trace the source and production process of each batch of raw materials to ensure the traceability of raw material quality.
2. Production process and equipment
Advanced production process: Tianya adopts advanced production process to prepare 2-Amino-5-chlorobenzotrifluoride, including key steps such as nitration and reduction. In the nitration process, the quality and yield of the nitration product are ensured by precisely controlling the reaction temperature, reaction time and the speed of adding mixed acid. In the reduction process, the iron powder reduction method is adopted to ensure the purity and stability of the reduction product by precisely controlling the reduction temperature and reaction time.
Advanced production equipment: Tianya has modern production equipment and production lines, including key equipment such as nitration pots, reduction pots, and distillation towers. These equipments are all well-known domestic and foreign brands, with the characteristics of high efficiency, stability and safety. Tianya also regularly maintains and maintains the equipment to ensure the normal operation and long-term stability of the equipment.
3. Quality control system
ISO quality management system: Tianya has established a complete ISO quality management system and obtained ISO9001 quality management system certification. The system covers the entire process from raw material procurement, production process, product inspection to after-sales service, ensuring that every link meets international standards and customer requirements.
Product Inspection and Testing: During the production process, Tianya conducts strict inspection and testing on each batch of 2-Amino-5-chlorobenzotrifluoride. This includes appearance inspection, purity determination, melting point determination, boiling point determination, refractive index determination, etc. to ensure that the product meets international standards and customer requirements. Tianya also regularly conducts stability tests and long-term storage tests on products to evaluate the stability and service life of the products.
Quality Traceability and Improvement: Tianya has established a complete quality traceability system that can trace back to the production process and quality test results of each batch of products. Once a quality problem is found, Tianya will immediately initiate the quality traceability procedure, identify the cause and take corrective measures. Tianya also regularly reviews and improves the production process and quality control system to improve product quality and production efficiency.
IV. Employee Training and Awareness Enhancement
Employee Training: Tianya pays attention to employee training and skill improvement. Regular professional skills training and quality management training are conducted for production personnel, inspection personnel and quality management personnel to improve their professional skills and quality management awareness. Tianya also encourages employees to participate in external training and exchange activities to understand the latest industry trends and technological advances.
Improvement of quality awareness: Tianya strengthens the quality awareness education of employees through internal meetings, bulletin boards, quality month activities, etc., so that employees can deeply understand the importance of product quality, establish the concept of "quality first", and ensure that they always maintain a high sense of responsibility and professionalism during the product production process.
