Empowering Coal Chemical Quality Inspection with Domestic Instruments | ZNYQ Changchun Intelligent Held Technical Exchange Meeting at National Energy Coal-to-Oil & Chemical Quality Inspection & Measurement Center
Aug 08,2026
Recently, Changchun Intelligent Instrument Equipment Co., Ltd. (ZNYQ) was invited to the on-site technical exchange meeting for domestic laboratory instruments held by the Quality Inspection & Measurement Center of National Energy Group’s Coal-to-Oil & Chemical Division. Our specialists delivered a special presentation on melt flow rate testers to the laboratory technical team of China’s leading coal chemical enterprise, boosting the domestic substitution of testing equipment for coal chemical material quality inspection with self-developed domestic instruments.
Centered on the core testing demands of polyolefin and plastic polymer raw materials in the coal chemical industry, our technical experts delivered a comprehensive presentation focusing on our flagship product, the SRZ-400A Fully Automatic Melt Flow Rate Tester. The presentation covered four major modules: Product Overview & Core Value, Core Functions & Technical Highlights, Equipment Technical Specifications & Compliance Standards, and Standard Operating Procedures & Full Lifecycle After-sales Service, fully demonstrating the comprehensive capabilities of ZNYQ’s domestic testing instruments to meet the stringent testing requirements of coal chemical laboratories.
During the interpretation of product value, our technical experts defined three core positioning points of the SRZ-400A:
- Benchmark for Quality Control: Delivers high-precision, highly repeatable Melt Flow Rate (MFR) test data for coal chemical production and quality inspection departments, ensuring consistent quality of finished polyolefin products.
- Accelerator for R&D: Supports new material formula research and process optimization trials, shortening the R&D cycle of new coal chemical materials and accelerating the industrial transformation of laboratory research achievements.
- Practitioner of Standards: The equipment strictly complies with authoritative domestic and international standards including GB/T 3682-2018 and ISO 1133-2005. Its test data boasts high authority and comparability, fully satisfying the compliance testing requirements of the Coal-to-Oil & Chemical Measurement Laboratory.
All attendees were frontline testing, metrology and R&D specialists from the Coal-to-Oil & Chemical Quality Inspection & Measurement Center. They listened intently to the technical sharing and engaged in in-depth discussions with our technical team on key topics including testing conditions for special coal chemical raw materials, long-term equipment stability, metrological calibration, and the implementation of domestic instrument substitution. Targeting industry pain points such as daily high-volume sample testing and continuous high-temperature, high-load operation in laboratories, our specialists proposed complete domestic testing supporting solutions by highlighting the SRZ-400A’s strengths including fully automatic intelligent operation, precise constant temperature control, automatic sample cutting & weighing, and automatic data storage & export, which won wide recognition from on-site technical staff.
For a long time, the coal chemical industry has relied heavily on imported instruments for polymer material testing, which brings pain points including high procurement costs, long maintenance cycles and delayed spare parts supply, hindering cost reduction and quality improvement for laboratories of major energy groups. With over a decade of dedicated R&D and manufacturing of melt flow index testing equipment, ZNYQ Changchun Intelligent continuously benchmarks the performance of international imported equipment. Leveraging self-developed core software and hardware technologies, we have built a full lineup of domestic melt flow rate testers that balance testing precision, operational stability and localized rapid after-sales service, making us the preferred brand for domestic instrument substitution in laboratories across energy, petrochemical, coal chemical and plastics processing sectors.
This technical exchange at China’s top coal chemical conglomerate marks a key milestone for ZNYQ to deepen its market layout in the energy and chemical track and advance the domestic substitution of high-end testing instruments. Moving forward, Changchun Intelligent Instrument Equipment Co., Ltd. will keep focusing on testing scenarios for coal-to-olefin products, new coal chemical materials and energy polymer products, continuously upgrading and optimizing instrument performance. We will provide stable, reliable and cost-effective domestic precision testing instruments alongside one-stop technical services for laboratories of major national energy and chemical central enterprises nationwide, and fuel the high-quality, independent development of China’s energy and chemical industry with robust domestic equipment.
