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

This 74% calcium chloride powder from Weifang Qihui Chemical Co., Ltd. is an industrial-grade chemical supplied in fine particulate form, with CaCl2 content guaranteed at minimum 74% by weight. The powder format offers rapid dissolution kinetics compared to pelletised grades, achieving homogeneous brine concentration within minutes in agitated systems. Originating from Weifang's Binhai Economical Development Zone, this material serves applications where immediate chemical availability outweighs dust control considerations, including accelerated concrete curing, brine refrigeration, and bulk de-icing solution preparation.

The powder consists primarily of calcium chloride dihydrate (CaCl2·2H2O), with typical particle size distributions ranging from 0.1-2.0 mm depending on milling classification. Standard industrial powder grades exhibit bulk densities of 800-1000 kg/m³, with higher surface area to mass ratios than pellets that increase both dissolution rate and moisture absorption from atmosphere. Flow properties vary with moisture content and particle morphology, with angular fractured particles showing poorer flowability than rounded granules. The material generates heat upon contact with water, with dissolution enthalpies sufficient to raise solution temperatures significantly above ambient.

Primary purchasers include concrete additive suppliers, oilfield service companies requiring completion brines, and industrial facilities operating absorption refrigeration cycles. The powder form is also directed to re-packagers who blend liquid de-icing solutions for regional distribution. Importers should note that powder handling requires dust extraction systems and personal protective equipment for respiratory and ocular protection. Packaging typically involves moisture-barrier bags with welded seams, though specific configurations must be confirmed directly with Weifang Qihui Chemical Co., Ltd. given variable minimum order quantities and container loading arrangements.

Weifang Qihui Chemical Co., Ltd. is located in the Binhai Economical Development Zone of Weifang city in Shandong Province, China. The supplier profile indicates an imported tier classification with harbor trust tier status. Platform-derived response metrics show zero recorded responses and zero average response hours, which limits assessment of communication reliability through standard channels.

The available profile does not disclose year of establishment, registered capital, production capacity, or workforce size. No named international certifications, laboratory accreditations, or major client references appear in the listing data. Buyers must independently verify manufacturing licences, environmental permits, and export qualifications before transferring funds or committing to contractual obligations.
