    Stabilization of Carbohydrate
 
 
 
Antraquinone liquid is a stable water-based   pulping aid, formulated to enhance the digester pulping process, and reduce pitch problems.
 
Antraquinone liquid improves the rate of penetration of the cooking liquor into the wood   chips, non- woods and grasses.  It accelerates delignification and stabilizes carbohydrates.   This combination of activities results one or more of the following:

APPLICATION
 
Antraquinone liquid   is  recommended  at  use  levels ranging  from  0.02  to  0.2%  based  on  cellulosic raw material weight.  The product should be fed to the cooking liquor main flow   line with a metering pump. After being uniformly dissolved and dispersed in the cooking liquor, Antraquinone liquid will immediately impregnate the wood chips upon contact. Dosages can vary depending on mill conditions, wood species and desired effects.
