SURFACE SIZING AGENT

GDPL offers full range of sizing agents to helps to improve the water resistance of paper and allows inks and pigments to sit on the surface of the fibers instead of being absorbed

    Benefit
  1. Wet end sizing can be reduced/eliminated
  2. Suitable for multi-purpose printing
  3. Improved surface strength (wax pick, IGT)
  4. Improves base paper/board for coating

PAC LIQUID

Paper manufacture - Used as a rosin sizing control in Neutral and alkaline paper Production affects the Drainage of liquor from the paper. POLY ALUMINIUM CHLORIDE provide many advantages for pulp and paper manufacture. Their range of applications xtends from process water and effluent treatment to paper making processes. The effectiveness of PAC compared to traditional coagulants like alum means that good results can be seen, even a low dosage levels. In papermaking operations, PAC is useful as a fixative to control anionic substances and as a retention / drainage aid.

PAC POWDER

Polyaluminium Chloride (PAC) is often referred to as the basic aluminium chloride or coagulant, it is between AICI3 and AI(OH) 3 between a water soluble inorganic polymer, the product has a strong bridge adsorption performance, during the hydrolysis process, accompanied by condension, adsorption and precipitation and other physical and chemical processes.
Polyaluminium Chloride, abbreviated as PAC, the appearance of the product is golden yellow, light yellow, brown and white powder.

ENZYMES FOR STARCH COOKING

When starch is heated with water, its granules swell and burst. As a result of this, Natural/Native starch changes into high viscosity solution. α-Amylase is used to cleave starch molecules to reduce the viscosity of natural starch and improve the overall condition of the paper.

WET STRENGTH RESIN

The cellulose fibreweb of paper is mainly held together by hydrogen bonds. These are dependent on physical contact between the fibres and can be broken by wetting of the fibres. The residual strength of a wetted paper can be less than 10% of the original strength.[1] Various techniques, such as refining of the pulp and wet pressing on the paper machine can be used to reduce the strength loss of the paper upon wetting. To improve the wet strength it is common to use chemicals. The use of chemicals can retain as much as 10% to 30% of the original dry strength of the paper.[1] The wet strength chemicals may improve the dry strength of the paper as well.
