摘要:
The invention relates firstly to a new mineral material treatment method using at least one amphoteric polymer, to make these mineral materials effective as an agent to reduce the quantity of natural and organic colloids in the manufacturing process for a sheet of paper. The second purpose of the invention is the treated mineral materials obtained using the method according to the invention. The third, fourth and fifth purposes of the invention consist of dry powders, aqueous suspensions and pellets of treated mineral materials obtained using the method according to the invention. A final purpose of the invention is the use of mineral materials treated using the method according to the invention as an agent to reduce the quantity of natural and organic colloids in the paper sheet manufacturing process.
摘要:
An aqueous fire resistance treatment composition consisting of water, sodium silicate, a calcined filler and a latent acid catalyst is disclosed. The composition may be applied to cardboard substrates such as corrugated cardboard. The composition is then cured to provide enhanced fire resistance.
摘要:
The present invention is drawn to a media sheets, including paper media sheets, which are effective for use in improving water fastness of inks, such as ink-jet inks. The media sheet can comprise a paper substrate, and a polydicyandiamide and a multivalent salt associated with the paper substrate. The polydicyandiamide and the multivalent salt are associated with the paper substrate prior to the ink-jet application.
