Paper Fixing agent

1.Introduction

Poly(Dimethyldiallylammonium Chloride)

Chemical Name: 2-Propen-1-aminium, N, N-dimethyl-N-Propenyl-, chloride homopolymer

CAS No.: 26062-79-3

2.SPECIFICATION:

content: 40%MIN

Viscosity: 8000-12000cps

PH:5-7

3.APPLICATION:

Used in paper pulp as a cationic fixing agent. Usually the slurry contains colloidal particles consisted of fiber material, additives and water, which are with anionic charge and interferes the papermaking process, it is also known as anionic trash; the interference is mainly in the following aspects:

1.influence wet chemical additives’ function, especially for cationic retention and drainage aids, sizing agent; or caused to increase the amount of wet chemical additives;

2. deposits in the machine system; interfere with the efficient papermaking machine.

3. COD discharge of sewage systems, increasing the load on the sewage treatment plant.

Recommended for use in mechanical pulp, chemi-mechanical pulp, secondary fiber pulp slurry and coating trash compound. Anionic trash neutralized by fixing agent can be bonded to the fibers so as to be taken away by paper sheet.

4.USING METHOD:

1. Adding methods: excellent water-solubility; can spread out in water in an instant. Dosing pump is generally used to drive it into a static mixer or a mixing pump , mixed with water, diluted to about 0.2% of the dissolved solution, and then into the slurry system.

2. Adding point: the general adding points is in front of flow system, that is, before the machine chest or fan pump; Or add in the pulp plant. Which is taken into consideration for the reaction time of the cationic fixing agent polymer molecules and garbage, also need to time and space for other wet end additives.

According to the slurry source, sometimes you need to select two or more points to add. When the slurry contains a source of coated broke, generally requires additional anionic trash fixative in the transport of the paper sheet.

3. Adding amount: anionic trash content is d measured by PCD (particle charge analyzer) cationic charge gauge in the slurry. The measure will directly show the dosage tips, but the real amount depends on the practical application. For general slurry, the recommend amount is in the range of 0.3kg ~1.8kg/t dry pulp.

5.PACKING:200KG PE drum or IBC drum.
