Shanghai Qixuan Chemical Technology Co., Ltd., a specialized enterprise in the fine chemical sector, has recently completed a major upgrade of its core laboratory processing equipment with the official commissioning of a new low-temperature high-speed grinding machine. Equipped with a high-efficiency chiller delivering ultra-low cooling temperatures down to -30°C and a full-range stepless speed regulation system covering 0 to 4,500 rpm, the newly installed unit is purpose-built for the precision grinding of pesticide emulsion formulations. It effectively addresses longstanding industry challenges associated with conventional emulsion grinding processes, including thermally induced material degradation, inconsistent particle size distribution and loss of bioactive components. This upgrade signifies Qixuan Chemical’s advancement toward high-precision, high-end formulation research and process optimization for pesticide emulsions, bolstering technological innovation and high-quality development within the agrochemical processing sector.
Pesticide emulsions are indispensable formulation products in modern agricultural pest management, widely recognized for their stable biological efficacy, superior substrate permeability and broad crop adaptability. In formulation R&D and manufacturing, the grinding procedure serves as a critical determinant of final product quality, directly influencing the dispersion homogeneity, particle size precision, active ingredient utilization efficiency and long-term storage stability of pesticide formulations. Traditional grinding equipment presents inherent technical limitations: intense frictional heat generated during high-speed operation elevates system temperatures rapidly. Given the thermosensitive properties of most pesticide technicals and functional adjuvants in emulsion systems, elevated temperatures commonly trigger active ingredient decomposition and volatilization. This not only compromises pesticide efficacy but also induces typical quality defects, including formulation turbidity, phase stratification and sediment formation. Furthermore, conventional devices lack precise speed modulation, failing to accommodate emulsion systems with varying viscosity and material properties. The resultant broad particle size distribution and insufficient micronization have consistently hindered the R&D and upscale production of premium-grade pesticide emulsion products.
To resolve prevailing technical bottlenecks in pesticide emulsion grinding, the newly commissioned grinding system at Shanghai Qixuan Chemical achieves groundbreaking advancements in temperature control and processing efficiency, with core performance metrics aligning with leading industry standards. Its dedicated chiller enables precise constant-temperature cooling as low as -30°C, establishing a full-process closed-loop low-temperature processing environment that completely eliminates heat accumulation during high-speed grinding. From a process mechanism perspective, ultra-low temperature induces embrittlement of rigid materials within emulsion matrices, substantially reducing grinding resistance. Beyond enhancing micronization fineness, this low-temperature paradigm fundamentally mitigates thermal deterioration risks, including technical pesticide decomposition, adjuvant inactivation and material oxidation. It preserves the structural integrity and biological activity of functional ingredients to the maximum extent, ensuring consistent and reliable formulation performance.
The system integrates a 0–4500 rpm full-spectrum stepless speed regulation module, enabling flexible parameter tuning based on the viscosity, raw particle size and customized process requirements of diverse emulsion formulations. It fully supports R&D, pilot testing and mid-scale manufacturing of various agricultural emulsions, including insecticides, fungicides and herbicides. The low-speed operating mode accommodates mild processing for high-viscosity, splash-prone emulsion materials, preventing material wastage and emulsion demulsification. Conversely, the high-speed mode delivers ultra-fine micronization, efficiently disintegrating particle agglomerates and achieving homogeneous dispersion of active ingredients throughout the solvent matrix. This effectively narrows particle size distribution span, improves emulsion uniformity and foliar permeability, enhances crop absorption of active components, and ultimately optimizes pest control efficacy in agricultural applications.
As an innovation-driven enterprise specializing in fine chemicals and agricultural formulation technology, Shanghai Qixuan Chemical prioritizes technological advancement as its core competitive advantage. The company focuses on emulsion formula optimization, process upgrading and novel adjuvant adaptation, adhering to the industry trends of high-efficiency, eco-friendly and safe agricultural plant protection while continuously refining core technologies and product quality. This laboratory equipment upgrade represents both a significant enhancement of hardware infrastructure and a strategic initiative to strengthen the company’s foothold in the high-end agrochemical market and break through critical process limitations. Compared with conventional grinding workflows, the novel low-temperature high-speed grinding system substantially improves the storage stability of pesticide emulsions, mitigates common quality failures such as stratification and precipitation, and extends product shelf life. In addition, its precise low-temperature processing minimizes raw material loss and reduces by-product generation, realizing synergistic benefits of cost optimization, efficiency enhancement and green manufacturing, which complies with the prevailing low-carbon and sustainable development principles of the modern agrochemical industry.
Pilot operation and comparative formulation tests conducted by Qixuan Chemical’s R&D team on multiple mainstream emulsion products have verified significant performance improvements. Samples processed under controlled -30°C low-temperature and calibrated rotational speed conditions exhibit more uniform particle size distribution, markedly higher active ingredient retention, as well as optimized transparency and fluidity. Such samples demonstrate superior efficacy stability and crop permeability compared with those produced via traditional processing methods, validating the prominent advantages of the upgraded process. Additionally, the equipment features stable operation, low acoustic noise, continuous cyclic processing capability and convenient routine maintenance. It comprehensively supports full-cycle laboratory operations, including new formulation development, process validation, sample characterization and small-batch trial production. This substantially elevates the laboratory’s R&D efficiency and technology translation capacity, laying a robust technical foundation for the company’s subsequent development and commercialization of high-performance, highly adaptable premium pesticide emulsion products.
Industry development trends indicate that the large-scale and refined progression of modern agriculture has raised stringent market requirements for the efficacy, safety and stability of agrochemical formulations. Outdated extensive manufacturing processes can no longer meet industrial upgrading demands, making low-temperature precision grinding a mainstream manufacturing technology for high-end pesticide emulsions. Leveraging the technical strengths of the newly upgraded grinding system, Shanghai Qixuan Chemical will further optimize its emulsion formulation systems, develop integrated processing solutions combining low-temperature grinding, precise speed regulation and high-precision dispersion, and tackle key technical challenges in high-end emulsion R&D to achieve iterative quality improvement of agricultural products.
Moving forward, Shanghai Qixuan Chemical will sustain investment in laboratory infrastructure and technological innovation. Empowered by three core strengths—advanced hardware configuration, optimized processing systems and innovative formulation technologies—the company will further deepen its layout in high-value agricultural fine chemicals. Committed to the R&D of green, high-efficiency pesticide formulations, Qixuan Chemical will continuously break through industrial technical barriers. Through sophisticated processing technologies, premium-quality products and professional technical services, the company will facilitate the green and high-quality development of modern agriculture and contribute innovative technological solutions to the upgrading of the global plant protection industry.
