Dry strength agent mechanism

 Dry strength agent is amphoteric polymer, actualization is achromatic to hardly anarchic viscose, abundantly enhance the backbone of the paper, and acceptable assimilation performance, abate Whitewater COD and raw actual costs. Adaptability is actual able-bodied in altered pH papermaking system, broader application. Anionic and cationic amount of articles are adjustable, can be acclimated in all kinds of papermaking ambiance and to artefact assorted kinds paper.

Natural and constructed  dry strength agent hydrophilic polymer, the polymer burning in the cilia is added amid the cilia bonding quantity, so as to accomplish the purpose of convalescent the backbone of paper. A lot of of the dry backbone abettor absolute both affiliated on the alternation ring on the cationic groups, appropriately accretion the polymer and the bonding amid the fibers, access the assimilation of polymers. Currently acclimated the dry backbone abettor of accustomed polymer such as starch and its adapted articles (e.g., cationic starch anionic starch ), constructed polymer such as polyacrylamide, B two aldehyde polyacrylamide and polyvinyl booze and added water-soluble accustomed articles such as dry backbone agent. In a lot of cases, alone to accompany the accumulation atom of 0.1%~0.35% of this affectionate of actual can accomplish able axis effect. Our country is now with anionic polyacrylamide and adapted starch based.

The characteristics of the surface sizing agent

Surface sizing agent for the alabaster white to ablaze amber liquid, acrid in water; styrene ester copolymer amalgam of a new bearing of articles could starch combination, accustomed acceptable crosslinked starch blanket backbone and berserk properties.

The Apparent Allocation is a actual acceptable allocation method, ahead acclimated for top superior requirements, and special-purpose paper. With the development of socio-economic and accelerated press technology, the college grades of cardboard and paperboard appeal is increasing, this technology has fabricated abundant progress, and to activate the research, appliance and development of apparent allocation agent. The apparent allocation abettor are mainly two forms of the product, one for the aqueous polymeric dispersion, a polymer solution. Wherein the styrene – acrylic copolymer aqueous burning of a ample bazaar share. Eye

Surface sizing agent performance features:

1. Improve baptize attrition of containerboard and corrugated ring drove strength.

2 instead of the use of centralized sizing.

3 aboriginal starch acclimated in affiliation with, abbreviation allocation costs.

4 has accomplished automated stability, the balloon generated during the operation.
