从China供应商批发进口74% Calcium Chloride Flakes — FOB条款

74% Calcium Chloride Flakes from Weifang Qihui Chemical Co., Ltd. are an industrial-grade desiccant and de-icing agent produced in Binhai Economic Development Zone, Weifang, China. The flakes contain 74% calcium chloride (CaCl2) by weight, offering strong hygroscopic properties and an exothermic dissolution reaction, which makes them effective for moisture control in various applications. The product dissolves rapidly in water, forming a solution that can depress freezing points to as low as -29°C.

Calcium chloride flakes are typically produced by evaporating brine solutions, resulting in a white to off-white crystalline solid. Industry-standard specifications for this grade include a pH range of 7 to 9 in a 10% solution, a chloride content of 74% ± 1%, and a maximum insoluble matter content of 0.5%. The flakes are free-flowing and non-caking under standard storage conditions, with a typical bulk density of 0.8 to 1.0 g/cm³.

Primary applications include de-icing roads and runways, dust suppression on unpaved surfaces, and as a drying agent in food processing and oil and gas sectors. The flakes are also used in concrete acceleration, wastewater treatment, and as a humidity control agent in storage facilities. Buyers should confirm the flake size distribution, as finer grades dissolve faster but may dust more during handling.

Weifang Qihui Chemical Co., Ltd. is based in the Binhai Economic Development Zone in Weifang, Shandong Province, China. The company specializes in the production of industrial chemicals, with calcium chloride flakes as a core product for de-icing and moisture control applications. Its harbor trust tier classification indicates a baseline level of supplier verification.

The supplier’s profile does not provide details on response rates, production capacity, or certifications, so buyers should directly request documentation such as ISO 9001 compliance, REACH registration, or food-grade certifications if applicable. Confirm the supplier’s ability to provide consistent quality and batch testing data, particularly for applications requiring strict purity or impurity limits.
