Abstract

The present invention is to provide a kind of paper industry and produce the new material of paper pulp and the processing method of this material, it mainly is the stem skin that makes after corn stalk is processed.The present invention has not only solved present paper industry raw material resources problem of shortage, and this stem skin also can be used for making high-strength fiberboard, and the residue after its processing can be used for making good feed and industrial chemicals.

Description

A kind of material and manufacture method thereof of papermaking slurry

The present invention is to provide a kind of paper industry and make the new material and the manufacture method thereof of paper pulp.

At present, China and countries in the world are with regard to paper industry, the raw material that the papermaking slurry is adopted is timber, reed basically ... the vegetable matter that content of cellulose is higher, wherein a large amount of employings is timber, will have every year a large amount of timber to be consumed by paper-making industry like this.Thus, paper-making industry all has the paper pulp raw material problem of shortage at present.Corn stalk is a kind of agricultural products of cheapness of wide material sources, and once the someone attempts to adopt it to make the raw material of paper pulp in one's early years, but leads to the failure owing to pulping rate is too low, and corn stalk also just is used for the uses of fuel or roughage until now.

Task of the present invention is the raw material resources problem of shortage at present papermaking slurry, and a kind of material and processing method thereof of producing the papermaking slurry that corn stalk is processed is provided.

The raw material of papermaking slurry provided by the present invention is that corn stalk is removed the stem skin that obtains behind leaf, the tip, the core through processing.Its process is: with corn stalk topping, the leaf → roll of drying, rub crowded → skin, core separation → packing with the hands.

Below process is described further:

Dry corn stalk can be that air dry forms, and also can be artificial drying.

Topping, leaf: can adopt cutting mechanics or rural area chopper commonly used that the tip of corn stalk is removed, comb slices off leaf again, promptly removes by this step part that cellulose is less, gives over to the processing feed and uses;

Roll, rub with the hands crowded: the straw that is about to remove the tip, leaf rolls with rolling tool, rolls in the process owing to roll and effect is squeezed in stranding simultaneously, makes the stem skin fully separate with inner core, and makes inner core obtain pulverizing;

Skin, core separate: though the stem skin that rolls, rubs with the hands after squeezing separates with inner core, but it is mixed in together mutually, can utilize the way of selection by winnowing or screening that it is separated, as adopting cyclopneumatic separator or vibrating screen etc. that quality is light and become pulverulent inner core to separate;

Packing: the stem skin that is about to obtain after skin, the core separation carries out Da Cheng Bales or packs being convenient to be transported to the paper mill, or directly utilizes the stem skin to enter the operation of papermaking slurry.

The present invention is owing to carried out processed with corn stalk, and what the stem skin that obtains mainly contained is cellulose, is applied to that pulping rate can reach 35～40% in the papermaking, has solved the problem of paper making raw material shortage of resources to a large extent.The stem skin that obtains not only can be used for making paper pulp and also can be used for making high-intensity fiberboard, and the residue core that obtains, the tip, leaf can become good good feed after crushed, or be used to brew alcoholic beverages, industrial chemicals such as alcohol.

Claims

1, a kind of is the material of the papermaking slurry made of raw material with the corn stalk, it is characterized in that: it is made of the stem skin that corn stalk is removed behind leaf, the tip, the core.

2, a kind of is the manufacture method that raw material is made the material of papermaking slurry with the corn stalk, it is characterized in that:

A, topping, leaf cut the tip, the leaf utilization of corn stalk and the comb segmentation method removes,

B, roll, rub with the hands crowded, will roll with rolling tool with the straw that removes the tip, leaf,

C, skin, core separate, stem skin, the inner core that rolls, rubs with the hands after squeezing separated,

D, packing are Daed Bales or packing with the stem Pi that obtains.
