| 摘要 |
<p>This invention relates to an improved press felt conditioning treatment which controls the deposition of particulate substances in papermachine felts. The treatment comprises applying to the felt during paper production an effective inhibiting amount of an aqueous solution containing a pH control agent and a nonionic or anionic surfactant. The surfactant is preferably selected from the group consisting of dodecyl benzene sulfonates, lauryl ether sulfates, octyl phenol ethoxylates, nonyl phenol ethoxylates, dodecyl phenol ethoxylates, primary alcohol ethoxylates, secondary alcohol ethoxylates, ethoxylated polyoxypropylene glycols, dialkyl phenol ethoxylates, polyoxyethylene sorbitan monoester, linear alkylbenzene sulfonic acids, sodium xylene sulfonate, linear olefin sulfonates, fatty amine oxides, phosphate esters, fatty imidazoles, carboxylated derivatives of fatty imidazoles, sulfonated derivatives of fatty imidazoles, fatty amidobetanes, fatty sulphoamido-betanes and mixtures thereof.</p> |
