Description
Technical field
The present invention relates to pulp technology for making paper, the method for conduit in more particularly, to a kind of quick-pick wood pulp material.
Background technology
Conduit is water conduction tissue (being equivalent to the blood vessel of human body) in broad-leaved wood, is thin by the very big tubulose of diameter
The end wall of born of the same parents is connected.It is present in a large number between the fibrous tissue of broad leaf tree, during trees grow up, play transporting tree
Liquid, is the pivotal role that plant conveys nutrition, and due to special transport function, its diameter is more much bigger than fibre diameter.Conduit divides
The shape of son differs, and different with seeds, common have cydariform, spindle, cylinder and rectangle etc..General ring porous wood earlywood portion
Vessel element mostly is cydariform, and the vessel element of late wood's part mostly is cylindrical and rectangle, and this is the feature comparing evolution.And be in
Fusiform vessel element is then original feature.
Conventional leaf wood slurrying assortment：Eucalyptus (includes tail alpine ash, Eucalyptus eamalducensis Dehnd．, lobule eucalyptus globuluss), yearning between lovers (inclusion Acacia mangiumwilld,
Acacia auriculiformis, lobule yearning between lovers, crassicarpa), 100,000 layers, Casuarina equisetifolia L. ... etc..These broad-leaved assortments have leading of oneself uniqueness
Ror molecule.Hardwood pulp slurrying low cost, can improve sheet uniformity and opacity, and to the bulk of paper, soft
Softness and absorbability are all highly beneficial, and leaf wood is made up of parenchyma cells such as conduit and the wood fiber, and in wood pulp material, conduit contains
Amount is often higher, and the intensity of conduit is less than fiber, if the quantity of conduit is more, the intensity being formed will reduce, therefore
Can there is surface strength problem, leaflet white point problem in the paper product that the high wood pulp material of conduit content is made.After paper pulp made by timber,
Its conduit form is substantially unchanged, how the conduit in separating, selecting hardwood pulp, domestic at present no concrete grammar research, utilizes
In wood pulp, conduit speculates pulping raw material so that the quality of papermaking has certain lifting.Chinese patent CN201420579373.4 is open
The detection means of conduit content in leaf wood slurry, quality that this detection means can accurately measure leaf wood slurry is given
Accurately assess.But this detection means is directly to use electron-microscopic analysis using after slurry dispersion, and slurry with microscope is
At one piece it is not easy to see the surface character of conduit clearly, do not determine belonged to which kind of seeds yet.It is thus desirable to a kind of quick-pick
The method of conduit in wood pulp material, convenient follow-up further observation conduit, can clearly see conduit external appearance characteristic, different conduits clearly
External appearance characteristic is different, and the impact for inferring conduit seeds source and analysis conduit provides early stage sampling method so that wood pulp material
The paper product quality made gets a promotion.
Content of the invention
In view of this, the invention provides in a kind of quick-pick wood pulp material conduit method, solve and can not separately choose
Select the problem of conduit, there is provided a kind of early stage is for the method for sample.
The technological means that the present invention adopts are as follows：In a kind of quick-pick wood pulp material, the method for conduit, comprises the following steps：
(1) wood pulp dispersion：Measure hardwood pulp and be placed in and discongest in device, add water, dissociation disperses to obtain first time slurry；
(2) wood pulp is collected：First time addition in pulp is filtered, obtains second slurry；
(3) wood pulp dyeing：Take second slurry, be placed on glass surface ware, the conspicuous Albert'stain Albert agent of Deca is dyeed, and places
Pulp suspension is made to dye；
(4) conduit is selected：Select the conduit of rectangular outward appearance after dyeing with the most advanced and sophisticated adhesion of fine needle, be placed in Deca He Shi dye
Secondary dyeing on the microscope slide of toner.
(5) observe：Microscope slide covered is observed.
Preferably, the hardwood pulp measuring 8g～15g in described step (1) is placed in and discongests in device, adds 1.5L～2.5L
Water, dissociation disperses to obtain first time slurry.
Preferably, the rotating speed discongesting device described in described step (1) is：10000～30000r/min.
Preferably, in described step (2), first time slurry is crossed screening on 300～350 eye mesh screens.
Preferably, in described step (2), the concentration of second slurry is 8%～12%.
Preferably, in described step (3), the taken amount of second slurry is 0.5g～1.5g.
Preferably, after the conspicuous Albert'stain Albert agent of Deca 5～10mL is dyeed in described step (3), place 2～5min, make to hang
Supernatant liquid dyes.
Preferably, the conduit of rectangular outward appearance after dyeing is selected in described step (4) with the most advanced and sophisticated adhesion of fine needle.
Preferably, utilize the form of micro- sem observation conduit in described step (5).
Using the method for conduit in a kind of quick-pick wood pulp material provided by the present invention, the present invention is simple to operate, separates
Conduit form afterwards preserves completely, and catheter surface pit etc. is clear, when subsequently checking using microscope, can clearly differentiate conduit
Mode of appearance, and operation equipment and personnel requirement relatively low, easy to operate, and can determine whether conduit seeds originate, be conduit observe
