Paper Making Amylase GR-M203

Product Profile

Starch, a high polymeric carbohydrate is a mixture of two polysaccharide, such as amylose and amylopectin. Special amylase enzyme can change the internal structure of starch, which will decrease the starch viscosity, thereby meeting the requirement in papermaking process.
GR-M203 is mainly used in the pulp and paper making industry (paperboard, culture paper, etc). 

Product Property

Appearance: amber liquid and light yellow powder (color maybe different with each batch, color do not influence the enzyme activity and effects)

Application

       1.  Adding time: add weighed dedicated amylase to brewed pot after original starch dissolved in brewed pot ( before heating gelatinization).

       2.  Gelatinization time: from heating to gelatinization finished (95℃) 25-30 minutes, keep temperature for 20 minutes, then cooling to 60-70℃(spend on manufacturers requirements).

       3.   Dosage of conversion agent:

      Batch:    GR-M203A (liquid)  : 100-150ml／t starch

                    GR-M203B (solid) : 100-150g／t starch

      Continuous system: GR-M203A(liquid) : 200-300ml／t starch

      4.  Specific dosage should be determined by laboratory testing viscosity according to manufacturers requirements.

Storage

Be stored in a cool, dry place and away from direct sunlight for 3 months under normal temperature(25℃).
