Definitions
- the present invention relates to a process for manufacturing paper and also relates to the paper thus obtained.
- the raw paper pulp consisting essentially of cellulose fibers is put into the form of a dilute aqueous suspension which is brought into the headbox of the paper machine from where it is distributed on a filter cloth on which the sheet is formed. of paper. This sheet is then wrung and dried.
- the qualities and properties of the paper obtained are determined in particular by the operating conditions of the paper machine, the raw pulp, the various additives that are added to the suspension before the sheet is formed and also the products that are coated. on the sheet of paper downstream of the filter cloth.
- mineral fillers such as CaCO 3 , TiO 2 , etc.
- Sizing agents such as those of the dimeric alkyl ketene family, are added to make the sheet resistant to liquids, therefore allowing the glued sheet of paper to be used for writing and printing.
- the air or "leaf formation” is of great importance and is representative of the general quality of the paper.
- the epair represents the greater or lesser homogeneity of the distribution of the fibers in the plane and the thickness of the sheet.
- the quality of the air will therefore have a considerable impact on the general quality of printing in the case, for example, of print-writing papers, and on the mechanical properties in the case, for example, of packaging papers.
- more and more additives are added to the suspension entering the headbox.
- the object of the present invention is, among other things, while retaining the quality of the air and the other characteristics of the paper, to obtain high retention rates as well as to allow improved drainage.
- the present invention makes it possible to achieve a higher charge, in particular in products sensitive to acids, and leads to less polluting releases.
- the present invention has for A process for manufacturing paper according to claim 1.
- the suspension containing the cellulose fibers can be raw or bleached pulp, bleached chemical pulp of softwoods or hardwoods or annual plants, unbleached chemical pulp of softwoods or hardwoods, mechanical pulps (SGW, TMP, CTMP, %) unbleached or bleached, de-inked bleached or unbleached pasta, pasta already containing additives, and mixtures thereof.
- the cationic starch - mentioned as component c) 1) - used according to the present invention is a mixture of one or more products sold under the generic name of cationic starch.
- Starch has an average molecular weight of 2.10 4 to 2.10 5 , preferably 3.10 4 to 12.10 4 .
- Cationic starches have a degree of substitution (DS) of between 0.01 to 0.1.
- the cationic starches are, for example, those described in Kirk Othmer, 3rd edition, volume 21, page 503. They represent by weight from 0.2 to 1.7% of the weight of the fibrous suspension entering the headbox.
- the PAC is present in the fiber composition entering the headbox at a rate of 0.01 to 0.3% by weight, relative to the weight of said fibrous composition, said percentage being expressed relative to Al 2 O 3 .
- the PAC is from WAC.
- the WAC corresponds to formula IV.
- the silica is present in the fibrous composition in an amount of 0.01 to 0.3% by weight, relative to the weight of said fibrous composition, the percentage being expressed as a percentage of active material, that is to say in SiO 2 .
- the anionic silica used is that which is in the form of a silica sol, advantageously at 15% of SiO 2 .
- the mineral filler - component a) mentioned above - can be one or more of the following conventionally used fillers, given by way of illustration: clay, CaCO 3 , hydrated alumina, talc, TiO 2 , etc.
- the mineral filler represents 5 to 30% by weight, preferably 10 to 25% by weight, of the weight of said fibrous composition.
- the preferred mineral filler is formed from CaCO 3 .
- the sizing agent - component b) mentioned above - can be one or more of the following agents conventionally used in neutral medium: dimeric alkyl ketenes (AKD), fluorinated phosphates, carboxylic anhydrides, styrene / maleic anhydride copolymers, and their derivatives .
- the amount of sizing agent used is between 0.01 and 2% by weight of commercial product at 6% of active material, relative to the weight of said composition.
- the bonding agent preferably used is AKD.
- the fibrous suspension can also contain conventional additives, such as dyes, optical brighteners, mechanical reinforcing agents, defoamers, antislimes (anti-deposition agent), as well as products chosen from the group consisting of: polyacrylamides , polyethyleneimines, carboxymethylcellulose, urea-formaldehyde resins, melamine-formaldehyde resins, aminopolyamide-epichlorohydrin resins, polyamide-epichlorohydrin resins.
- additives such as dyes, optical brighteners, mechanical reinforcing agents, defoamers, antislimes (anti-deposition agent), as well as products chosen from the group consisting of: polyacrylamides , polyethyleneimines, carboxymethylcellulose, urea-formaldehyde resins, melamine-formaldehyde resins, aminopolyamide-epichlorohydrin resins, polyamide-epichlorohydrin resins.
- WAC is a product marketed by ATOCHEM and corresponds to a poly aluminum chloride of formula IV at 10% Al 2 O 3 .
- the silica is in the form of a silica sol and is commercially available under the name CECASOL from CECA.
- the cationic starch is that manufactured by ROQUETTE and marketed under the name HICAT 142.
- the AKD sizing agent is manufactured by HERCULES and marketed under the name AQUAPEL.
- test 1 there is a very significant improvement in the air caused by the use of WAC instead of silica, a result consistent with what one skilled in the art expects. .
- Test 3 shows the synergy that the association of small quantities of silica develops in the presence of WAC. At equivalent thickness, retention is increased by 10 points, ie an increase of 15 to 20%. This results in less pollution of the water in the circuits and greater ease of treatment of waste water at a lower cost.
