Definitions
- the present invention relates to a method and apparatus for producing microfibrillated cellulose fibres.
- Chemical pulp is a lignocellulosic fibrous material prepared by chemically separating cellulose fibres from a fibre-containing material. Chemical pulp is produced by combining fibre-containing material and chemicals in large vessels known as digesters where heat and the chemicals break down the lignin, which binds the cellulose fibres together, without seriously degrading of the cellulose fibres.
- fibre-containing material is later to be understood as a wide concept comprising wood chips, grass and other fibre-containing materials originating from the vegetable kingdom, which have been crushed into pieces of appropriate sizes so they can be fed into the device.
- microfibrillated cellulose is also known as nanocellulose. It is a material typically made from wood cellulose fibres, both from hardwood or softwood fibres. It can also be made from microbial sources, agricultural fibres such as wheat straw pulp, bagasse, bamboo or other non-wood fibre sources. In microfibrillated cellulose the individual microfibrils have been partly or totally detached from each other. A microfibrillated cellulose fibre is normally very thin ( ⁇ 20 nm) and the length is often between 100 nm to 10 ⁇ m. However, the microfibrils may also be longer, for example between 10-200 ⁇ m, but lengths even 2000 ⁇ m can be found due to wide length distribution. Microfibrils that are separated and located in a water phase of slurry are included in the definition MFC.
- “Refining” of chemical pulp in a refiner is the mechanical treatment and modification of fibres so that they can be formed into paper or board of desired properties.
- a standard height of the refiner blades when refining fibres is in the range 6-10 mm. This is due to the runnability issues and that the pressure difference must be maintained. Wear of the refiner blades is another issue that is crucial so therefore, a certain height of the blades is needed.
- the apparatus according to the invention is characterized in that the apparatus is a refiner for refining chemical pulp with refiner blades, wherein the height of the refiner blades are in the range of 2-3 mm and wherein the cutting edge length (CEL) value of the refiner is higher than 70 km/rev.
- CEL cutting edge length
- the pulp is highly refined and have a SR value above 50, preferably above 60 .
- the blocking of the refiner blades is prevented due to the lower fibre length and reduced flocking and dewatering tendency of the pulp.
- the no load energy i.e. energy taken by the refiner without the pulp, no load is measured by running refiner with water only
- the no load energy per produce ton of fibres is much less than when using several refiners.
- the method comprising the steps of:
- Pre-treating of chemical pulp such that, the pulp reaches a Schopper-Riegler (SR) value above 50. This may be made by pre-refining of the chemical pulp.
- SR Schopper-Riegler
- the pulp is refined, at a consistency of 3-6%, in a refiner with refiner blades, wherein the height of the refiner blades is in the range 2-3 mm.
- the cutting edge length (CEL) of the refiner during refining is preferably higher than 70 km/rev.
- the surface edge load (SEL) during refining is preferably lower than 0.5 and more preferred lower than 0.3.
- the refining is performed in an alkaline environment where the pH is higher than 8, preferably higher than 9.
- the alkaline environment and the short refiner blades facilitate the refined fibres to slip through the refiner.
- the temperature during refining is higher than 40° C., preferably higher than 50° C. Conventionally, it is difficult to keep these high temperatures, but thanks to the low height of the refiner blades this matter is facilitated. The low height also gives a more even temperature during refining.
- the rotation speed of the refiner blades during rotating is about 1000-1600 rpm.
- the refiner is preferably a conical refiner.
- the invention has several benefits in comparison to prior art, such as:
