从China供应商批量进口Akd Sizing Agent

Hubei Jiayun Chemical Technology Co., Ltd. produces an AKD sizing agent formulated as a white emulsion with a solid content of 15% ± 0.5% and a pH range of 3-5. The product carries a cationic charge and is designed for rapid ripening in neutral to alkaline papermaking systems, with a stated general resistance to water penetration of 60 seconds under machine conditions. The supplier recommends a dosage of 5-10 kg per ton of absolute dry pulp, delivered via metering pump into the mixing tank, high tank, or slurry pipeline. This formulation uses a proprietary polymer emulsifier based on petroleum resin rather than conventional starch emulsifiers, which the supplier claims improves retention, reduces particle size, and cuts dosage by more than 15% compared with standard AKD products.

The emulsifier system incorporates cationic surfactants to achieve high charge density and uniform dispersion. The product is stable for three months when stored sealed at 5-30°C. For optimal performance, the supplier advises maintaining a forward mesh headbox pH of 7.0-8.5 and ensuring at least one drying cylinder operates at 95°C or above. The formulation is compatible with calcium carbonate filler systems and is positioned as a replacement for traditional rosin sizing and conventional AKD neutral sizing agents. Polyacrylamide (6.0 million molecular weight, 200-300 g per ton dry pulp) is recommended as a retention aid.

Paper mills converting from acidic to neutral/alkaline papermaking constitute the primary buyer segment. The product serves manufacturers of printing and writing papers, packaging boards, and other grades requiring controlled water resistance. Packaging is in 200 kg or 1000 kg sealed plastic barrels for room-temperature indoor storage. Importers should confirm freight classification for liquid chemical transport, verify drum integrity standards for ocean shipment, and discuss Incoterms directly with the supplier, as no terms are stated in the listing.

Hubei Jiayun Chemical Technology Co., Ltd. is located at 2# Yehe Road, Liukou Industrial Park, Xiantao, 433000, in Hubei Province, China. The supplier is classified as an imported-tier account on the platform with a harbor trust designation. The response rate is recorded at 0.00% with zero average response hours, which indicates either a new listing, limited platform engagement, or data that has not yet populated. Buyers should not assume responsiveness based on this profile and should initiate contact through multiple channels to gauge actual communication speed.

The company positions itself as a developer of proprietary emulsifier technology, specifically highlighting independent development of a petroleum-resin-based polymer emulsifier for AKD sizing agents. No verified certifications, production capacities, year of establishment, or client references appear in the available data. The listing focuses entirely on technical product claims rather than corporate credentials. Importers should conduct standard due diligence: request business registration documents, quality management certificates, and references from existing paper industry customers before committing to trial orders.
