Cationic cassava starch high DS 0.040 CAS NO.65996-62-5

Cationic starch YS-018C Instruction

1. Introudction

YS-018C quaternary ammonium cationic starch is produced by natural starch and quaternary ammonium salt treated by anti-swelling, activation and other methods, which changes the chemical structure of the D-glucopyranose unit in the starch molecule, thereby changing the physical and chemical properties of natural starch. a modified starch.

Its appearance is basically the same as that of natural starch, but it has many advantages compared with natural starch, mainly in that the gelatinization temperature is reduced, the Zeta potential is raised to positive, the application range is very wide, and the viscosity, transparency and stability of the paste liquid are obvious. improve.

This product can obviously improve the physical properties of paper such as bursting strength, tensile strength, folding strength, lint resistance, etc.; it can improve the sizing effect of rosin gum, AKD emulsion and other sizing agents; it can improve the water drainage of pulp and papermaking. Speed; improves retention of pigments, fillers and fines.

II. Technical indicators

III. Characteristics

1. The gelatinization temperature is low, the paste liquid is clear and transparent, and the storage time is long.

2. It can adsorb negatively charged fibers and fillers, thereby improving the retention rate of fine fibers.

3. Due to the effect of high potential, starch, fibers and fillers can flocculate, speed up water filtration, increase the speed of the paper machine, reduce the concentration of white water, reduce pollution, and reduce energy consumption.

4. It can form hydrogen bonds with fibers and fillers to increase the internal bonding force, so it can improve the dry and wet strength of paper and cardboard, especially the dry strength, and reduce the interruption of the papermaking process.

5. The moisture, viscosity and degree of substitution in the product can be provided according to user requirements within the specified range, with great adjustability.

6. Reduce the amount of sizing agent in the pulp.

7. It can be used as ASA, AKD emulsifier, and can be used in the production of cationic styrene-acrylic surface glue.

IV.  Paste preparation

1. Intermittent gelatinization: Add starch into cold water to make 5-6% starch slurry, stir evenly, heat up to 85℃, keep warm at 85℃-95℃ for 15-20 minutes, add cold water to dilute to 3% Reserve for left and right, add cold water to dilute to about 1.0% before use.

2. Continuous gelatinization: It can be gelatinized according to the specific situation of the user. The gelatinization concentration is 5-8%, and the gelatinization temperature is 105℃-135℃.

V. Packaging and storage

25kg/bag, 500Kg/bag.

Store in a cool, dry and ventilated warehouse;
