PAPER PROCESSING CHEMICALS
     
   Pulp and paper industries are undergoing phenomenal expansion to meet the growing market demand. Many pulp and paper industries adopt novel process methods to improve the final product to stay ahead of their fellow players.   
    Chemicals used in every stage of the pulp and paper industry play a predominant role in making good and consistent quality paper.  
  DIGESTOR ADDITIVES:  
 A specially formulated product to improve the penetration of alkali into the cell wall of wood fibres in digesters. While doing so, it improves the cooking efficiency and reduces the consumption of alkali used in the cooking process. This product is biodegradable and non hazardous in nature.
  WASH AID:  
   A dual functional silicone base liquid product meant to use in the brown stock washing of the pulp mill.  This product provides better washing and cleaning of the pulp fed through counter current washers. Less alkali loss and less consumption of water for washing are the benefits derived from this product.  
  DYE-FIXING AGENT:  
 As the name precisely indicates this product controls the consumption of the dye being used in the dyeing process. Excessive usage of dye result in shade difference and loss of dye. The dye fixing agent allows only the limited quantity of dye at optimum level thereby eliminates the wastage.
PEROXIDE STABILIZER:
 Peroxide used in the bleaching process tends to decompose quickly. Therefore it's consumption goes up beyond the desirable dose to the pulp. To prevent the decomposition and to optimize the dose of peroxide, the stabilizer for peroxide is recommended.
SLIMICIDES: 
 During the pulp process, due to the environmental conditions the pulp is prone to slime growth. The presence of slime effects breakage of paper at the dry end. Slimicide effectively kills the responsible bacteria completely and ensure no breakage in paper.
DE-INKING CHEMICALS:
 In a waste paper recycling process, it is necessary to remove the inks in the de-inking cell for further processing. Different type of non-ionic polymers are recommended after lab scale evaluation for de-inking performance
  FELT CLEANING CHEMICALS:  
 This enables the stickies and deposits get removed from the felt which otherwise affects the drainage of wet pulp.
PITCH DISPERSANT:
 White and dark pitches are commonly found in pulp processing sequence. It affects the quality of pulp and paper to a greater extent. Pitch dispersant disperses all grades of pitch instantaneously and avoid rejects and downtime.
FLUFF CONTROLLER:
 It fixes the fines which are otherwise cause fluff in the drier end. Printability is affected by the fluff in paper. The suitable fines fixing agent ensures fluff free operation.
 
DRY STRENGTH ENHANCER :
 This is a well refined water Soluable. Polymerized Powder grade product, specifically designed to have cellulose fiber linkage.
This Enhances Strength Property (burst factor improvement). This can be used in Kraft and white varieties of paper.
