Abstract
The present invention relates to a kind of manufacture method of xylon grey cellulose powder, it is characterized in that being completed by lower following procedures：Raw material screening, once high temperature drying, crushing, secondary fine grinding, pack storage etc., this method changes traditional chemical method for Physical, as conventional method needs acidifying, the chemical process of basification is changed to simple physical crushing processing, using it is traditional with bleaching broad-leaved pulp board be that primary raw material is changed to use and is considered as the saw foam of waste as primary raw material by people, and this method has simple and easy to apply, raw material is discarded object, produce at normal temperatures, without chemical process such as acidifying, alkalization, it is free from environmental pollution, production cost is low, is conducive to popularization and application feature.
Description
Technical field
It is a kind of manufacture method of xylon grey cellulose powder the present invention relates to cellulose manufacturing technology field.
Background technology
Lignocellulosic is a kind of raw material of industry product for being widely used in the industries such as food, medicine, process hides.Early in eight
The lignocellulosic of China relies primarily on import before the ten's, and general standard is Italy and Nippon Standard in the world.Eight
After the ten's, China starts to develop and produce lignocellulosic.It is the technique using broad-leaved pulp board as main production raw material
Method use chemical method, i.e. the broad-leaved pulp board to bleaching to be hydrolyzed, acid treatment, alkalization, drying, crushing, pack etc.
Technological process.Therefore, this method is complicated, and production cost is high, low production efficiency, unstable product quality, and price is high, influence
Its popularization and application.The present invention is to provide a kind of manufacture method for the wooden essential color fiber element for being mainly used in leather industry, using quilt
The sawdust that people are considered as waste is primary raw material, and this method is simple and easy to apply, and raw material is discarded object, is produced at normal temperatures,
Without chemical process such as acidifying, alkalization, free from environmental pollution, production cost is low, is conducive to popularization and application.
The content of the invention
A kind of manufacture method of xylon grey cellulose powder, it is characterised in that completed by following procedures：
A, raw material screening
The sawdust for selecting broadleaf tree processing is raw material, and screening process sieve removes the impurity of sawdust, it is ensured that sawdust it is pure
Cleanliness；
B, high temperature drying
The sawdust of leaf wood is carried out with drying plant to dry under high temperature, the moisture content of the sawdust after drying must not exceed
5-7%；
C, once crush
Once crush to refer to and first time crushing is carried out to the sawdust dried by high temperature with pulverizer, and make after crushing for the first time
The fineness of sawdust reaches 200-280 mesh；
D, secondary fine grinding
Sawdust after first time crushes is carried out second to refine, using airslide disintegrating mill, revolution can reach 2600 turns/
Point, the powder after this time refining is xylon grey cellulose powder, and fineness is 400 mesh, and sieving rate is 90%, and moisture content is 3-
5%, pH value is 5.5-6, and unit weight (proportion) is 0.44, and ash is 1.47-1.48%；
E, pack storage
To be tested according to xylon grey cellulose powder made from above-mentioned operation, pack of weighing, be then put in storage, take 25 public
One bag of jin is standard, through examining qualified storage.
The present invention compared with prior art, has the characteristics that：
1st, raw material sources are extensive, price is low.Original production raw material is the pulp board of paper grade (stock), is changed to use sawdust, can both save mesh
The nervous paper making pulp of preceding domestic contrast, while this discarded object of sawdust is turned waste into wealth again, reaches twice laid.
2nd, production cost is greatly reduced, domestic broad-leaved pulp board is 3500 yuan/ton or so at present, produces wooden fibre
The ratio of dimension element can produce 1 ton of lignocellulosic for ton pulp board of 1.3: 1, i.e., 1.3, along with product people such as other acid, alkali
Work, with water, electricity, vapour etc., production cost per ton is up to 5000 yuan/ton or so.And be raw material with broad-leaved sawdust, through screening, drying,
Crush, the lignocellulose production cost per ton of fine grinding production is only thousand yuan or so.
3rd, technological process is simplified, the method for original production lignocellulose is chemical method, and the present invention then uses physics
Method, as long as can standard up to standard by dry, crushing for the first time, fine grinding by the broad-leaved sawdust through screening.It is this wooden through experiment
Essential color fiber element powder, as the additive of leather manufacture, is very popular, the manufacture method of this product is simple thing
Reason processing, can solve the environmental pollution caused due to acidifying, alkali process, purify environment, thus, the present invention profit
State is favorable to the people.
The production method (manufacture method) thinks the technology through Forestry University, the relevant expert of forestry general bureau, scholar's demonstration
It is advanced feasible, and the product of this method production, i.e., xylon grey cellulose powder is through Forestry University college of materials science and engineering
Detection indices reach or better than existing standard (such as table 1).Particularly this xylon grey cellulose powder is through bright north
Plastic cement leather Co., Ltd tests extremely successful in leather production, and by the favorable comment of user, unanimously thinks that the product exists
A kind of indispensable additive, excellent are used as in leather production.
