  • Description: The invention discloses an assistant specially used in a papermaking digesting technology. The assistant comprises, by mass, 50-100 parts of trifluoromethanesulfonic acid, 50-100 parts of paratoluenesulfonic acid, 20-30 parts of polyoxyethylene nonyl phenyl ether, 30-40 parts of a nonionic surfactant, 10-15 parts of styrylphenol polyoxyethylene ether, 10-15 parts of phenylethylphenol polyoxyethylene ether, 1-5 parts of an alpha-alkynol anthraquinone derivative, 2-5 parts of menadione, 5-10 parts of nonylphenyl polyoxyethylene ether, 5-8 parts of dodecyl polyoxyethylene ether, 5-10 parts of polyethylene glycol dodecyl phosphate, 3-5 parts of dioctadecyl phosphate, 5-10 parts of sodium silicate, 5-10 parts of 1,5-naphthalenedisulfonic acid disodium salt, 3-5 parts of sodium tripolyphosphate, 3-5 parts of sodium metaphosphate and 150-250 parts of water. The assistant specially used in a papermaking digesting technology shortens the digesting time of a pulp, obviously improves the drainability, improves the dispersion state of fibers, and improves the single stage bleaching degree.
