从China供应商批发进口74%Min Calcium Chloride Dihydrate White Pellets — FOB条款

Weifang Yitong Chemical Co., Ltd offers calcium chloride dihydrate in white pellet form, with a stated minimum calcium chloride content of 74%. The dihydrate composition (CaCl2·2H2O) provides a stable, free-flowing pellet shape that reduces dust generation during handling compared to powder equivalents. The supplier is based in Weifang, Shandong Province, with operations referenced from a central business district address rather than a production facility location.

Pelletised calcium chloride dihydrate at 74% minimum purity is produced by prilling or extrusion of concentrated brine solutions, followed by controlled cooling and screening. The white colour indicates low iron content, typically below 50 ppm for this visual grade, though specific iron analysis should be requested. Standard pellet diameters for industrial calcium chloride range from 2-5mm for broadcast spreader applications, with 4-8mm also common for bulk handling systems, confirm Weifang Yitong's actual sizing. The dihydrate form contains approximately 23.5% water of crystallisation by weight, which is chemically bound and not available as free moisture, this distinction matters for accurate stoichiometric calculations in concrete acceleration and other weight-critical applications.

Primary applications include winter road de-icing (where pellet form resists wind deflection better than powder), concrete curing acceleration (ASTM C494 Type C accelerator), dust suppression on unpaved surfaces, and industrial desiccant systems where gradual moisture absorption is preferred. Buyers include municipal road maintenance departments, ready-mix concrete producers, mining operations for haul road dust control, and chemical distributors serving oil and gas drilling markets. For procurement, confirm with Weifang Yitong whether the pellet specification matches your spreading equipment, and verify whether the quoted 74% refers to CaCl2 content on an anhydrous basis, dihydrate basis, or as-received basis, as this affects effective dosage calculations by 20-25%.

Weifang Yitong Chemical Co., Ltd lists its address at Room 1520, Jintai Building, on Dongfeng Street and Changsong Road in Weicheng District, Weifang, Shandong Province, China (postal code 261000). This central business district location suggests trading or sales office functions rather than primary manufacturing, though the company may operate production facilities elsewhere in the Weifang region. The supplier carries a harbor trust tier with zero recorded response rate and zero average response hours, indicating limited or no engagement through platform-mediated enquiry systems.

The company profile provides no information on year of establishment, number of employees, annual revenue, production capacity, or specific manufacturing certifications. No ISO certificate numbers, SGS report references, or other verifiable quality credentials are disclosed in available data, despite generic claims of compliance. The listing positions Weifang Yitong as a supplier of bulk calcium chloride dihydrate pellets for industrial applications, with emphasis on de-icing, concrete curing, and moisture control. Importers should conduct independent verification of the company's manufacturing credentials, request factory audit reports or third-party inspection certificates, and clarify whether Weifang Yitong manufactures directly or sources from third-party producers in the Weifang chemical cluster.
