Pulping cooking catalyst

CG-II series of pulping cooking catalyst
Characteristics:
CG-II series of pulping cooking catalyst is the latest generation of pulp cooking for high efficient catalyst afterwards anthraquinone and anthraquinone derivatives. It has the wetting, penetration ability that anthraquinone and alkali sulfide could not be comparable. It can make the cooking solution rapidly wetting materials surface and penetrate into the fiber material. It shortens the cooking time, effectively protects the fiber strength, improves pulp yield.
Application:
The product has a wide range of adaptability to the fiber material. It can be used for alkaline pulping of wheat straw, rice straw, Chinese alpine rush, reed, bamboo, bagasse, wood and other raw materials.
In the cooking of caustic soda, ammonium sulfite and sodium sulfite method, it can reduce 1% -3% alkali dosage, improve fine pulp yield 1% -3%; The pulp color is lighter. It can reduce the drift rate of 1%.
In the Kraft process it can reduce the sodium sulfide dosage more than 80%. Cooking straw material can be completely without sodium sulfide, thus greatly reduce the pulp costs and reduce environmental pollution. It not only has no any adverse impact on alkali recovery system. Recovery of its system is not only without any adverse effects, on the contrary the qualified rate of the strong white liquor muddy corrosion-degree is up to 100%. The service life of leaf filter, and can be increased several times, and it can reduce the scaling phenomenon in the cooking container and pipeline.
Product advantages:
The catalyst, compared with the anthraquinone and sodium sulfide, under the same process conditions, has the following obvious advantages:
1. Automatic biodegradation, safety, high efficiency, no pollution;
2, The fine pulp yield increase 1-3 percentage points;
3, Water filtering performance improve significantly. More than 0.2 g wet weight increase;
4, The brightness of single stage bleached pulp increases 1% -3% on average;
5, The total cost of per ton pulp can reduce 50-100 Yuan. (USD 0.82-1.65 0
The dosage and usage:
This product is added 0.05% when cooking straw material (on absolute dry material), and 0.1% when cooking bamboo and wood materials (on absolute dry material). This product can be added directly to alkali tank. After stirred evenly, it is added to the cooking tank with lye or scattered in several times.
Package, transportation and storage
1. 25 kg lined with plastic film woven bag (also according to user’s requirements)
2. Stored in a cool and dry place. Be valid for one year.
