Definitions
- the present invention relates to a liquid paper deinking composition, used in the regeneration of pulp from old printed papers from newspapers, magazines, photocopies and computer papers.
- the present invention also relates to the use of a liquid deinking composition for deinking paper.
- the subject of the present invention is a liquid deinking composition as well as its use, suitable for deinking paper by flotation and / or washing, making it possible to obtain a regenerated pulp of high quality having a high whiteness index and a content residual in very low ink and ensuring a stable and reliable deinking process.
- the deinking operation is very important because it represents one of the fundamental steps for recycling old paper.
- the conventional and usual methods of deinking old paper to provide basic material for papermaking fall into two categories; the first is a deinking process by flotation and the second is a deinking process by washing.
- deinking processes essentially consist of two phases. The first consists in defibrating the old paper, an operation also called pulping, and the second in removing the ink by flotation or washing.
- the first phase is carried out by bringing old paper into contact, with stirring, with water and a chemical system generally comprising a silicate, a basic agent, a soap or a surfactant, for example an ethoxylated and / or propoxylated fatty alcohol. , and a bleaching agent, introduced separately.
- a chemical system generally comprising a silicate, a basic agent, a soap or a surfactant, for example an ethoxylated and / or propoxylated fatty alcohol.
- a bleaching agent introduced separately.
- the pulp is diluted and transferred to a flotation cell into which air is injected through the bottom of the tank. A foam is then produced which entrains the ink particles, either by overflowing the tank in which the pulp is located, or by suction.
- the pulp is diluted and washed in water, then separated from the ink particles dispersed in water by filtration or centrifugation, this step being repeated as much as necessary in order to obtain a pulp whose qualities are suitable for reuse.
- a third alternative is to combine the washing and flotation steps to separate the ink from the pulp.
- the chemical systems used for deinking are generally selected according to the mode of separation of the pulp and the ink particles.
- the chemical system For separation procedures by washing, the chemical system must be almost non-foaming in operational conditions in order to limit any mechanical problem with the devices used.
- the ink particles to be extracted from the pulp must be fine and well dispersed in the presence of the chemical system to increase the efficiency of the separation of said particles and obtain a high quality pulp.
- the chemical system must have greater foaming properties than that of washing processes.
- the ink particles in this case adhere to the foam generated within the flotation cell, which thus allows their separation from the pulp.
- the ink particles must be able to agglomerate in order to form large aggregates, also facilitating and increasing their separation from the pulp and their elimination by air bubbles.
- the Applicant has developed a new liquid paper deinking composition which can be used both in deinking processes by flotation, and in deking processes by flotation and washing.
- the new liquid composition according to the invention provides a high quality regenerated pulp with a high whiteness index and a very low residual ink content, while ensuring high performance and reliability in the industrial process using said composition.
- the liquid composition according to the invention has the advantage of being completely non-ecotoxic, and therefore its use for deinking paper has almost no impact on the environment.
