Papermaking industry --- Coating and surface sizing

Oxidized starch

Feathers

1.    Oxidized starch has high whiteness

2.    Good freeze thawing resistance

3.    Paste is clear and has good stability, low viscosity, weak retrogradation, strong adhesive force, good film-forming property

4.    Strong adhesion, high penetrability

5.    It has good intermiscibility with other chemicals

 

Functions and advantages

1.    Improve paper surface smoothness, reduce paper surface powder, make paper more delicate

2.    Improve paper surface strength, such as bursting strength, folding strength, etc.

3.    Improve degree of paper sizing, paper picking speed, physical strength

4.    Improve paper printability

Applications

1.    As adhesive for laminated paper, paperboard pasting and bonding corrugated paper

2.    In papermaking industry, used as surface sizing agent, coating adhesive agent, wet-end additive

3.    In packing industry, used as paper products adhesive. It can be compound in cold water, and has some advantages, such as fast drying, paperboard stiffness is good, good freeze thawing resistance, no moisture absorption, no whiskering, strong adhesive relay, etc. Suitable for manual single machine, veneer machine, glue machine, tube coiling machine, paper tube machine, etc.

 

 

Papermaking industry --- Paper pulp additive / Wet end additive

Cationic starch

Feathers

1.    Cationic starch has strong adsorption force to fiber and filler in paper pulp. It is widely used as fortifier, retention agent, filter aid, etc. in papermaking industry

2.    As the degree of substitution increases, the paste’s viscosity, transparency and stability are enhanced obviously

 

Functions and advantages

1.    Improve paper bursting strength, tension stress, folding strength, resists shedding and other physical property

2.    Improve the sizing effect of rosin and bauxite

3.    Improve paper pulp drainability and forming & pressing speed

4.    Improves retention rate of various dyes and fillers, such as clay, titanium dioxide, calcium carbonate, etc. which can save cost for papermaking

5.    As fixative and emulsifier for latex, synthetic resin, alkyl vinyl ketone dimer, etc., dispersant for neutral sizing agent

6.    Reduce the degree of waste water pollution, beneficial to eliminate public hazards
