High Quality Modified Starch Used in Surface Sizing for Paper Making

Oxidized starch is an important kind of modified starch, which is white in color, easy to gelatinize, easy to control the gelatinization temperature, high transparency, good film-forming property, strong adhesive force and high stability. It is widely used in papermaking, textile, food and other industries. widely.

Product performance

1. The viscosity of the product can be specially processed within the range required by the user, which has a high cost performance.

2. The paste liquid has strong cohesive force and high stability. Long-term use will not cause excessive fluctuations in viscosity, ensuring the stability of ring compressive strength and water absorption of corrugated paper.

3. The paste liquid has good film-forming property, which is more uniform than native starch, and can effectively improve the ring pressure strength.

4. The impurity and protein content of this product are very low, the hydrophilicity of the particles increases, no peculiar smell, the paper has good water resistance and is not easy to absorb moisture.

5. At the same time, oxidized starch is also used in textile and food industries.

一、  Suggested method of use

1. Under stirring, add the product into cold water, adjust it to a suspoemulsion with a concentration of about 2% - 6% (the concentration of special high-strength paper will reach 10%), spray it between the papers, and in the later stage During the heating process, it gelatinizes and plays a bonding role.

2. Generally, the amount of paper per ton is 20-60 kg, and some high-strength paper types can reach 100 kg.

3. The increase or decrease of the dosage mainly depends on the adjustment of the water spray volume of the nozzle, the number of the nozzle and the pressure of the booster pump.

4. Pay attention to adjust the temperature and pressure of the oven to ensure that the starch can be completely gelatinized.

Storage and packing:

1. Packing: net weight 25kg/ bag (can also be adjusted according to needs).

2.Store in a dry, ventilated and cool place.

3. Storage period: 24 months.

4. Oxidized starch ensures safe use and does not affect human health.

Application 

1. Application in oil drilling, used as slurry stabilizer and Water retaining agent

2. Application in paper industry, used as surface sizing agent, surface coating agent, wet additive and adhesive in corrugated paper

3. Application in textile industry, used as sizing agent in yarm, veil.
