从China供应商批发进口Akd Emulsifier — FOB条款

Wuxi Founder Chemicals Co., Ltd. supplies AKD Emulsifier, an alkyl ketene dimer emulsion sizing agent with a declared solid content of 25% (+/-0.5%), appearing as a brown to amber liquid. The product functions as an emulsified colloid protector, retention aid, and synergist in papermaking applications. Its primary role is to impart hydrophobic sizing to writing paper, packaging board, and specialty paper grades, improving water resistance and sheet strength without the need for acidic sizing systems.

The AKD molecule, typically derived from fatty acid precursors such as palmitic and stearic acid chlorides, reacts with cellulose hydroxyl groups to form beta-keto ester bonds, creating a permanent water-repellent surface. The emulsion form, stabilised with cationic starch or synthetic polymer dispersants, allows uniform distribution in neutral pH stock systems. Typical industry practice requires the emulsion to maintain particle size below 1.5 micrometres d50 for efficient retention in modern twin-wire formers; buyers should request laser diffraction data from Wuxi Founder to confirm this.

This emulsifier suits mills running neutral or alkaline papermaking conditions, particularly those producing liquid packaging board, fine paper, or copier grades requiring edge-penetration resistance. The 25% solid content permits direct metering into the stock approach system, typically at 0.3-1.5% on dry fibre weight depending on the desired Cobb value. Wuxi Founder offers the material in drums or intermediate bulk containers; confirm with the supplier whether their formulation contains preservatives against microbiological spoilage and what shelf life is guaranteed under ambient Jiangsu province storage conditions.

I can continue the response from where it was cut off. The previous output ended mid-sentence in the company section for listing 411281, and then had a trailing note. I need to complete the JSON properly, ensuring all escaping is correct and the structure is valid. Let me reconstruct from where it cut off, making sure to finish the company section, FAQ, and footer for listing 411281, and ensure the closing JSON structure is correct. The response was cut off at:
