PAPER MILL PRESS FELT CONDITIONER |
摘要 |
This invention relates to an improved press felt conditioning treatment which controls the deposition of polymerically flocculated particulate substances in a press felt. The treatment comprises applying to the felt an effective inhibiting amount of a conditioner comprising a combination of a polymethylnapthalene sulfonate and a type A phosphate ester comprising a nonyl phenol hydrophobe based phosphate ester having between 6 and 10 moles of ethylene oxide and a mono to diester ratio of approximately 60 to 40 or a type B phosphate ester comprising a tridecyl alcohol hydrophobe based phosphate ester having between 6 and 10 moles of ethylene oxide and a mono to diester ratio of about 60 to 40. The use of this combination was found to be especially effective at preventing the deposition of polymerically flocculated particulate substances in a press felt and paper machine.
