Reason, wherein the temperature of drying process is 35-45 DEG C, drying time 1-2h, and dried object is made, spare；
3) dried object made from step 2 is poured into together in three-dimensional motion mixer and carries out mixed processing, wherein three maintenance and operations
The speed of mainshaft of dynamic mixing machine is 10-13r/min, incorporation time 3-5h, and mixture is made；
4) mixture made from step 3) is poured into pelletizer and carries out granulation processing, wherein when being granulated processing in machine barrel
Temperature is 50-60 DEG C, and granular auxiliary agent is made.
The beneficial effects of the present invention are: not only can effectively adsorb the moisture in paper pulp, and ingredient drops into paper pulp
In it is advantageous to papermaking；Using granular structure and possess preferable intensity, addition and dosage are easy to control, it is only necessary to pour into
Into wet paper pulp, auxiliary agent is separated with paper pulp again after mixing water suction, it is easy to use.
The characteristics of being the principle of dewatering of pulp auxiliary agent below or effect:
Atlapulgite: be with clay being raw material, handles through inorganic acidifying or salt or other methods, then is made through water rinsing, drying
Adsorbent, appearance is off-white powder, and odorless, tasteless, nontoxic, absorption property is very strong, due to for off-white powder, to paper pulp
Color influences it is less.
Acrylyl oxy-ethyl-trimethyl salmiac: being a kind of chemicals, and molecular formula is, for producing water process flocculation
Agent, antistatic coating, paper making additive, chemicals, textile auxiliary agent etc. are finely from molecule product.
Sepiolite fibre: silicate mineral of the sepiolite as a kind of layer of chain, in structure among two layers of oxygen-octahedron
One layer of magnesia octahedron is pressed from both sides, the layered structure unit of 2: 1 types is formed.Its tetrahedral layer is continuous, the direction of active oxygen in layer
Periodically reverse.Octahedral layer forms the spaced channel of upper and lower level.The orientation in channel is consistent with fiber axis, allows
Hydrone, metal cation, small organic molecule etc. enter wherein it is possible to play outstanding water sorption, while as reinforcing agent,
Whole intensity can be promoted, product can be prevented because water swelling is the case where leading to be easy to appear abrasion and fall off, and
Due to its Filamentous fibre structure, drop into also less on the influence of the papery for the paper made in paper pulp.
Peach gum: being peach naturally secret, and can absorb water the hair that rises, and can play the role of water suction, while using again as binder.
Four acicular type zinc oxide crystal whisker: its three-dimensional crystalline structure dispersion plays skeleton function, unique three-dimensional space in the base
Between structure keep it bigger with the gripping power of matrix, reinforcing effect is more significant, obviously increases tensile strength, and horizontal and vertical
Tensile strength numerical value is essentially identical, isotropically reinforces the mechanical performance of basis material, improves matrix strength significantly and adds
Work performance.Intensity can effectively be promoted by compounding with sepiolite fibre, prevent product from leading to be easy to appear mill because of water swelling
The case where damaging and falling off mixes with paper pulp and can be promoted the mechanical property of paper pulp since it is with outstanding reinforcing effect, right
The negative effect that paper pulp is made into is few.
Titanium dioxide: the amphoteric oxide of white powder has hydrophily and hygroscopicity, and titanium dioxide is that the world is more white
Thing, especially bleached paper less to the Color influences of paper.
Pollen pini: pollen pini not has very strong water imbibition, non-stimulated to skin, and undesirable shadow will not be caused to human body
It rings.
Gluten: being the native protein extracted from wheat, water imbibition, liposuction and good mechanical performance,
Glutenin molecule is threadiness, and molecular weight is larger, has elasticity, but extensibility is small, crude, at the same in paper pulp
Plant is similar, and biggish side effect will not be generated ingredient drops into paper pulp.
Oxidized starch: make a kind of converted starch obtained from starch oxidation.Product colour is pure white, be widely used in weaving,
Papermaking, food and Fine Chemical.In paper industry, be used as Cypres, coating binder, wet end additive, watt
Corrugated paper board adhesive.Starch water swelling can play good drying effect to paper pulp, and dropping into paper pulp can be with
Play preferable beneficial effect.
Crystalline aluminosilicate compound: having regular and uniform duct in its crystal structure, rate of moisture absorption is exceedingly fast, in pole
A large amount of moisture content are absorbed in the short time.
Sodium carboxymethyl starch: white powder is added in filler and is used as stabilizer, thickening cementation is played, with peach gum, sea
Afrodite fiber and four acicular type zinc oxide crystal whisker compounding, can effectively promote whole stability, and dropping into paper pulp can
So that paper gloss is bright-coloured, improve the printing performance of paper, enhances the toughness and wearability of paper.
Microcrystalline cellulose: being the cellulose of a kind of purifying, part depolymerization, white, odorless, tasteless, by small porous particle group
At crystalline powder can play the role of absorbing moisture since it is with porous structure.Simultaneously microcrystalline cellulose molecule it
Between there are hydrogen bond, hydrogen bond association when compression, therefore the compressibility with height, be often used as can be improved particle in binder
Hardness.The heat resistance for improving oxidized starch, to promote yield rate.
Water-based zinc stearate: it has wide range of applications, and can be used as release agent, color preserving agent, lubricant, interleaving agent etc., can be with
Reduce the friction between auxiliary agent finished product and paper pulp.
Nanometer calcium carbonate: it is good with resin compatible, it can effectively improve or adjust the rigid of product, toughness, finish and curved
Qu Qiangdu；Improve processing performance, improve product rheological property, dimensional stability, heat-resistant stability have filling and enhancing,
The effect of toughening.Also there is excellent ink absorption and high drying property, can ink is preferably attached in paper pulp
On plant fiber, beneficial effect is caused to paper.
