Weifang Jiangchang Chemical adheres to the core R&D principles of “scenario-specific adaptation, environmental protection first, and global compliance,” continuously increasing investment in the research and development of green, low-corrosion halide products. Annual R&D expenditures consistently account for 7%–10% of the company’s total revenue. To date, the company has obtained 3 utility model patents and 2 software copyrights, with its core technologies fully implemented across production lines.
The company’s two major self-developed technological systems are as follows: First, a purification process for low-corrosion, long-lasting snow-melting formulations, leveraging calcium–magnesium chloride compound modification technology to address longstanding industry challenges such as high corrosion, damage to pavement vegetation, and severe soil salinization caused by conventional de-icing agents. Second, a multi-stage brine purification technology that enables graded purification of calcium chloride and magnesium chloride products, ensuring that food-grade products meet heavy-metal content levels far below national standards and satisfying the demand for high-purity raw materials among manufacturers of soy products, beverages, and livestock and poultry feed.
On the hardware front, the company is equipped with a complete set of automated production equipment for brine purification, evaporation and crystallization, and automatic packaging. It currently operates six standardized, fully automated production lines, covering specialized lines for dihydrate calcium chloride, anhydrous calcium chloride, magnesium chloride, refined industrial salt, and environmentally friendly de-icing agents. The laboratory conducts round-the-clock quality inspections, monitoring all process parameters from raw brine to finished product release, resulting in a customer after-sales quality dispute rate of less than 0.8%.
The company’s technical team boasts many years of cross-border experience in the salt chemical industry, with a thorough understanding of the chemical trade regulations and industry准入 standards of Russia, Central Asia, and Southeast Asia. They can adjust product specifications according to the regulatory requirements of target markets, customizing specialized raw-material formulations tailored to local compliance standards. In addition, the company provides 24/7 multilingual foreign-trade technical specialists to assist overseas factories, municipal projects, and traders with free product selection and technical guidance on low-temperature formulation design. Should quality issues arise, the company offers returns or exchanges and covers associated logistics costs.
