Special pulping Enzyme GR-M204
Product description:

Special pulping Enzyme GR-M204

GR-M204 is the special enzyme used for chemi-mechanical pulping and long fiber pulping. It is extracted from three special-effect enzymes and is suitable for the range of pH 5.0-8.0 and temperature 22-65 °C. Based on its effects to fibers in pulp, GR-M204 can make the fibers absorb adequate water and expand and promote fiber brooming, so reduce the energy consumption in the subsequent pulping process. Because the fibers absorb enough water and are fully expanded, they become soft and thickening, and increase the bulk and flexibility. At the same time, GR-M204 can re-combine the fiber fines, which is conducive for water draining of wet sheet, can reduce the fiber fines content in white water and improve the recycling rate of white water, thereby reduce consumption and clear water usage per ton primary pulp. GR-M204 has certain stripping roles to slime pulp adhered in the system, long tome use can make the entire approach system of paper machine more, avoid the paper flaw such as color spot and paper breakage phenomenon resulting from slime pulp, reduce the cleaning frequency of forming wire and blankets and prolong the life of forming wire and blankets.

Properties:

  • Optimum pH value: 6.5-7.5
  • Effective PH value: between 6-9
  • Optimum dosage: 45-70g/t pulp

Advantage:

  1.  Polymerization capability
Polymerization capability can re-combine fine fibers in pulp. When pulping specific enzyme be added to pulp, it encounters those fine fibers remaining in pulp firstly, surround these fine fibers with its quantitative superiority more than tiny fibers myriad times to make fine fibers re-combined together, when these chain fits crash with macrofiber, attaches to macrofibers, meanwhile due to the very small volume of pulping specific enzyme microorganisms, after added to pulp, it will be crashed out even contact with macrofibers in advance. But when they recombine with fine fibers to major volume, superadd its adhesiveness, they will recombine with macrofibers naturally when encounter macrofibers later. The property of pulping specific enzyme brings advantages as follows:

  1)  Reduces the white water concentration of paper-making machine, promote retention, reduce unit pulp consumption, improve unit time output.
  2)  Paper machine part close recycling water becomes clearly clean, which can reduce cost of water treatment or reduce amount of added clear water.
  3)  Improve the strength of short fiber part-paper, which can reduce the matching of paper high quality raw material, create benefits for enterprise.
  4)  Increased drainability of pulp obviously, rotate speed of paper machine can be improved, thus improve production or reduce available machine time. 

  2.  Sub-wire broom effect 
Pulping specific enzyme GR-M204 bio enzyme direct act on fiber surface, make smooth fiber surface produce many branches, which get sub-wire broom effect, this property brings advantages as follows:

  1)  Because the connection between fiber and fiber changed to multi-point connection after sub-wire broom, the paper strength、bursting strength、tearability are all improved, plus fines fibers recombined on these sub-wire broomed fibers, the paper quality is further improved, thus improved market competitiveness for enterprise product.
  2)  Because the improved bursting strength can decrease high quality raw materials matching, create benefits for enterprise.

  3.  Water absorption swelling effect
    Pulping specific enzyme GR-M204 make fiber interior loosen, thus make fiber easier to absorb water swell, the advantages are as follows:

  1)  Fiber be soft after imbibition, so that can save wasting energy of millstone defibrination, create benefits for enterprise.
  2)  Thicken finished paper, which is called thicken paper in status ration.
  3)  Synthesize above advantages, enterprise can reduce pulping beating degree appropriately under the condition that guarantee every finished paper quality index invariable, meanwhile reduce energy consumption.

  4.  Bacteriostat and clean system capability.           
GR-M204 has certain stripping roles to slime pulp adhered in the system, long tome use can make the entire approach system of paper machine more, avoid the paper flaw such as color spot and paper breakage phenomenon resulting from slime pulp, reduce the cleaning frequency of forming wire and blankets and prolong the life of forming wire and blankets.

  Synthesize above advantages:

Pulp after adding pulping specific enzyme becomes more clean, Improves degree of whiteness, extends life of paper blankets and product quality, decrease energy consumption without pollution.

Packaging:

20kgs per drum, specific packaging and weight can be determined by user requirement.

Attention Matters:

Avoid contact skin and eyes. Please rinse with water if leakage occur. Use clean and dry implements and utensils when accessing and transfering GR-M204 from the container for use. 

Storage: 

Store in a cool, dry place and away from direct sunlight. The reduction of its activity will be no more than 10% when stored properly for up 1 year. Sealed after use.
