Technical Specifications

Manufacturing Process Flow and Quality Assurance for Agrochemicals

The production of the Agrochemicals Selective Herbicide Acetochlor 25% Atrazine 25% Nicosulfuron 2% OD is a meticulously controlled process, engineered to ensure consistent quality, stability, and efficacy. Unlike mechanical components that undergo casting, forging, or CNC machining, agrochemical manufacturing focuses on precise chemical synthesis, formulation, and comprehensive quality control. This product exemplifies advanced formulation technology, crucial for delivering effective pesticides and agrochemicals.

Key Stages of Oil Dispersion (OD) Formulation:

1. Raw Material Sourcing & Qualification:

   High-purity technical grade Acetochlor, Atrazine, and Nicosulfuron, along with specialized co-formulants (e.g., non-ionic/anionic surfactants, polymeric dispersants, carrier oils, rheology modifiers), are sourced from qualified global suppliers. Each incoming batch undergoes rigorous inspection to verify purity, concentration, and absence of contaminants, aligning with ISO 9001 standards for raw material quality and traceability. Only materials meeting stringent specifications are approved for use.

2. Pre-treatment & Dissolution/Dispersion:

   Solid active ingredients (Atrazine, Nicosulfuron) are typically pre-milled or micronized to achieve a specific particle size distribution, essential for stable OD formulation. Acetochlor, often liquid, is precisely measured. The active ingredients are then systematically dispersed or dissolved in an appropriate non-aqueous carrier oil, alongside selected emulsifiers and dispersants to ensure robust stability and prevent phase separation during storage and dilution.

3. High-Shear Mixing & Wet Milling:

   The mixture undergoes intense high-shear mixing, typically followed by wet milling using specialized equipment like horizontal bead mills. This critical step further reduces the particle size of the solid active ingredients into the sub-micron or nanometer range. Precise control of particle size distribution is paramount to enhance suspension stability, optimize sprayability, and maximize the bio-availability and efficacy of the active ingredients upon application. In-process quality checks for particle size and viscosity are continuous.

4. Stabilization & Homogenization:

   Additional stabilizers, anti-foaming agents, and rheology modifiers are incorporated to prevent sedimentation, flocculation, or creaming over the product's shelf life. The entire blend is then thoroughly homogenized to ensure a uniform distribution of all components, maintaining the physical and chemical integrity of the OD formulation. Advanced analytical techniques, including spectroscopy (e.g., FTIR) and chromatography (e.g., HPLC), are employed to confirm ingredient uniformity and stability.

5. Final Quality Control & Packaging:

   Before packaging, the finished product undergoes a comprehensive battery of final tests. These include precise active ingredient content analysis (e.g., by HPLC-MS), measurements of pH, density, viscosity, suspensibility, pourability, and accelerated storage stability tests (e.g., at elevated temperatures per CIPAC methods). Only products meeting stringent internal and international standards (e.g., FAO specifications, ANSI/ASAE S387.2) are approved. The product is then accurately filled into appropriate high-density polyethylene (HDPE) container111s, sealed, and labeled according to local and international regulatory requirements. The service life of the herbicide, under recommended storage, is typically two years, ensuring consistent performance. Target industries for such high-quality products are predominantly large-scale agricultural operations, particularly those focused on cotton. The advantages in typical application scenarios include energy saving through reduced spray passes, enhanced efficacy requiring lower application rates, and improved equipment longevity due to the non-corrosive properties of the OD formulation.
