从China供应商批发进口Activated Bleaching Earth Use For Oil Refining — FOB条款

Activated bleaching earth is a natural bentonite-derived adsorbent based on activated montmorillonite clay, engineered for the refining and decolorization of vegetable and animal oils as well as select mineral oil streams. This material functions through selective adsorption of pigments, phospholipids, soaps, and oxidation byproducts, with performance calibrated to AOCS reference standards for edible oil processing. Guangxi Longan Ruifeng Industrial & Trading Co., Ltd. supplies this grade in 25 kg multi-wall bags or 1 MT bulk bags, positioned for bulk oleochemical and food-processing buyers sourcing from China.

The clay undergoes acid activation to enlarge its internal surface area and develop enhanced cation-exchange capacity, which distinguishes it from simple natural bentonite. Particle size distribution is typically controlled to 200-325 mesh to balance filtration rate with adsorption kinetics, while moisture content is held below 12% to prevent hydrolytic degradation during storage. The neutral pH profile of this grade reduces the risk of free-acid carryover into finished oil, a common failure mode with strongly acidic activated earths. Standard packaging uses moisture-resistant woven polypropylene with polyethylene liner to maintain activity during ocean transit.

Primary applications span edible vegetable oil refining (soybean, palm, sunflower, cottonseed, rapeseed, peanut, coconut, corn, olive, rice bran, palm kernel, linseed, castor, jojoba, and canola), animal fat processing (tallow, fish oil, lard), and industrial mineral oil treatment including paraffins, waxes, insulating oils, and waste lubricating oil regeneration. Buyers typically include integrated oilseed crushing mills, standalone refineries, biodiesel producers, and oleochemical manufacturers. Trade terms, lead times, and exact MOQ should be confirmed directly with the supplier, as these are not specified in the source data.

Guangxi Longan Ruifeng Industrial & Trading Co., Ltd. is located in Nanning, Guangxi Zhuang Autonomous Region, with the address listed at postal code 530000. The company holds a Harbor trust tier on the platform, which represents a baseline verification level rather than an advanced assurance status. The response rate is recorded at 0.00% with zero average response hours, indicating no historical inquiry engagement is captured in the available data. Buyers should treat direct communication as essential and may wish to request verification documents or arrange third-party confirmation before committing to orders.

The supplier's product focus centers on activated bleaching earth for oil-refining applications across edible, animal, and mineral oil sectors. No manufacturing plant details, production capacity figures, year of establishment, employee count, revenue data, or client references are provided in the source profile. The listing does not cite ISO, HACCP, Halal, Kosher, or other certifications relevant to food-contact materials. Buyers are advised to request a current certificate of analysis (COA) for each batch, confirm the acid-activation protocol used, and validate that the neutral pH claim is supported by independent testing before finalizing supply terms.
