Akd Wax

Akd wax is pale yellow waxy flake solid which is widely used in the paper industry as sizing agent. Our akd wax is a neutral sizing agent which can directly react to fiber with high content and i2, assay and low acid, and is more efficient sizing agent without organic impregnant like toluene¯benzene¯ and so on. After sizing with akd emulsion, it can make paper less water absorbing and controls its printing properties. It is welcomed by the paper mills all over the world.

AKD wax(Alkyl ketene dimer) for akd emulsion used as paper internal sizing agent
AKD wax, alkyl ketene dimer wax, can be divided into 3 models: AKD 1840, AKD 1865 and AKD 1895, is mainly used for internal sizing of various paper, such as copper plate base paper, copy paper, archival paper, high quality writing paper and corrugated paper.
AKD wax is usually used together with AKD emulsifier, AKD dispersant, AKD stabilizer to make AKD emulsion.
AMAZON provide technical support for new customers in AKD emulsion production process.

AKD wax introduction
Chemical name: Alkyl Ketene Dimer
Alias: AKD wax
AKD powder is also called AKD wax. Chemical name is Alkyl ketene dimer. CAS registration number is 144245-85-2. Appearance is pale yellow flake or granular solid. It is produced by fatty acid (C16), via acylation and dehydrochlorination to become AKD wax. AKD wax is mainly used for papermaking neutral sizing agent. R or R' in the above structural formula is the alkyl group, and a series of alkyl ketene dimers can be obtained through modifying different alkyl groups. Octodecane and cetane are applicable to the papermaking neutral sizing agent.

Alkyl ketene dimer is a white-to-yellow solid with the melting point of about 47 ~ 51 , which can be soluble in ethyl alcohol, benzene, chloroform and other organic solvents. The reactive group of alkyl ketene dimer-ketone group has high activity
and makes esterification reaction with the hydroxyl in cellulose.

Product Application
AKD wax can be made into AKD emulsion applied as in sizing agent in the papermaking production.

AKD wax is emulsified by the cationic emulsifier, and melted AKD wax and emulsifier undergo high-speed shearing and high pressure homogenization to form the liquid AKD sizing agent after cooled.
In the papermaking process, application of AKD sizing agent gives the fluid resistance to paper and paperboard to prevent or delay the penetration and diffusion of some liquids on paper fibers, thus satisfying people's requirements on the processing and use of paper products.

AKD contains hydrophobic group and hydrophilic group, which are well distributed in the sizing process to transfer to locate the process of bonding with cellulose. AKD emulsion particles stay between negatively charged paper fibers since they carry with
positive charge by virtue of cationic starch and PAM and other retention agents; In the pressing and drying process of the paper machine, these globular AKD particles are easily expanded and distributed on the surface of fibers due to the lower melting point to form a homogeneous cover film; When paper is dried and stored for a period, the active group (lactone ring) on AKD molecule makes the esterification reaction with the hydroxyl on fibers under certain conditions to be binding on fibers in the form of fixed covalent bonds. Hydrophobic long-chain alkyls transfer to the paper surface in order to give the penetration resistance to paper.
