摘要:
A method of improving retention and drainage in a papermaking process is disclosed. The method provides for the addition of an associative polymer, prepared by an inverse emulsion polymerization process that utilizes multiple, discrete additions of initiator. Additionally, a process for preparation of an associative polymer, prepared by an inverse emulsion polymerization process that utilizes multiple discrete additions of initiator is disclosed.
摘要:
Disclosed herein are hydrophobically-modified poly(aminoamides) useful as fixative detackifiers for stickies and pitch control in papermaking processes. These polymers are prepared via modification of amine-containing water-soluble poly(aminoamides) with reactive functional group-containing hydrophobic compounds. In particular, poly(aminoamides) may be modified, under appropriate reaction conditions, with long chain alkyl glycidyl ether, AKD (alkyl ketene dimer), ASA (alkyl succinyl anhydride), or Quab (3-chloro-2-hydroxypropyl-N,N,N-dimethylalkyl ammonium chloride). These novel polymers are effective in inhibiting deposition of organic contaminants in pulp and papermaking systems.
摘要:
The invention relates to a stable aqueous slurry composition comprising clay or clay-like material, hydrophobically associative polymer, and optionally a surfactant; and a method of inhibiting the deposition of organic contaminants in pulp and papermaking applications.
摘要:
Methods for inhibiting the depositions of organic contaminants from pulp in pulp and papermaking systems are disclosed. Hydrophobically modified poly[ethylene glycol] are added to the pulp or applied to deposition-prone surfaces of a papermaking system.
