Abstract

A process for physically extracting bamboo fibres includes such steps as cutting short, rolling to become sheets, digesting for removing saccharide, fat, protein and starch and splitting, mechanical beating and tearing to open bamboo fibres, screening and drying. It can be used as the substitute of glass fibres with low cost.

Description

The technology of extracting bamboo fibre by physical method

Affiliated technical field:

The present invention relates to a kind of bamboo wood deep processed product and process, particularly a kind of processing technology that adopts the method extraction bamboo fibre of pure physics.

Background technology:

Bamboo fibre is a kind of novel fibrous material; many good performances are arranged; particularly has very high environmental protection characteristic; just progressively be familiar with,, utilized its very high strength character as substitute and some specific use of some fiber by common people; the instead of glass fiber; eliminate the environmental pollution of glass fibre, the environment of preserving our planet, as be used for automobile industry etc.Utilize its fiber finer, hollow, very high absorbing sweat ability and gas permeability preferably, and unique resilience, become a kind of new material of textile industry, replace some textile fiber material.Utilize its filtering function strong, non-environmental-pollution is used for some sewage disposal again, and as the building sewage disposal, tap water filter is handled.Fiber dust can be used for special smelting industry, makes reducing agent and uses.Along with bamboo fibre by people's further understanding, his application will be more and more widely.

Goal of the invention:

The purpose of this invention is to provide a kind of diameter that extracts in 0.03-0.4 millimeter, length method at the natural bamboo fibres of 10-250 millimeter, this bamboo fibre is different from and generally is tubbiness or block bamboo fibre, also is different from the polymerization bamboo fibre that forms with other fiber blends in the textile industry.

The basic principle of production technology of the present invention is: former bamboo (bamboo chip) is adopted the method for pure physics, divides silk by boiling, desaccharification, degrease, protein, after starch is handled, through mechanical impact, tear, shredding becomes bamboo fibre.

Technological process of the present invention is: former bamboo cut-out, roll extrusion burst, boiling divide silk, fiber to extract, screening is dry, packaging and warehousing.

Concrete processing step of the present invention is as follows:

A, former bamboo cut off: former bamboo or bamboo chip are cut into ring more than 50 millimeters with artificial or mechanical system;

B, roll extrusion burst: adopt the roll extrusion wafer separator that ring roll extrusion shredding is become bamboo chip;

C, boiling divide silk: the bamboo chip through the roll extrusion shredding is put into boiling container, adds water to the water surface and exceeds bamboo chip more than 10 millimeters, sends into after the boiling under 1-6 atmospheric condition in the roll extrusion branch silk machine and carries out the branch silk, obtains the bamboo chip of expanded metals shape; Or earlier the bamboo chip of roll extrusion shredding is sent into roll extrusion divide carry out the branch silk in the silk machine after, put into boiling container boiling under 1-6 atmospheric condition again;

D, fiber extract: the bamboo chip of expanded metals shape is sent into carried out the fiber extraction in the fiber extractor, obtain containing the bamboo fibre of impurity such as bamboo powder, bamboo head, bamboo stalk, tabasheer;

E, screening are dry: sieve with artificial hand-sort screening or mechanical system or streamer mode, obtain pure bamboo fibre after, place natural air drying under the sunlight, or carry out drying with drying room, drier, the water content to bamboo fibre is 3-30%;

F, packaging and warehousing: to pressure packing after the product inspection.

Product standard of the present invention:

1, appearance color is yellow; Diameter in 0.03-0.4 millimeter, length at the 10-250 millimeter;

2, free from admixture, worm-eaten, mildew and rot;

3, moisture is controlled at 3-30%;

4, the content of bamboo powder, bamboo stalk, bamboo head is not more than 20%;

Process of the present invention is applicable to the substitute of glass fibre and the production of effluent treatment and filtering net inner layer material, and by the result of use comparative analysis, this product can satisfy the serviceability requirement fully, the very high value of environmental protection is arranged again, and financial cost is low.

The specific embodiment:

Concrete processing step of the present invention is as follows:

A, former bamboo cut off: with former bamboo or bamboo chip is split with artificial cutter or mechanical system cuts into 1000 millimeters ring;

B, roll extrusion burst: adopt the roll extrusion wafer separator that ring roll extrusion shredding is become bamboo chip; The nip roll of length direction of bamboo and roll extrusion wafer separator meets at right angles, and purpose is to be convenient to boiling and to do preliminary treatment for the branch wire process, and the roll extrusion wafer separator can adopt another utility model patent equipment " the roll extrusion burst divides a silk machine " of the applicant.

C, boiling divide silk: the bamboo chip through the roll extrusion shredding is put into boiling container, adds water to the water surface and exceeds 10 millimeters of bamboo chips, sends into after the boiling under 1 atmospheric condition in the roll extrusion branch silk machine and carries out the branch silk, obtains the bamboo chip of expanded metals shape; Or earlier the bamboo chip of roll extrusion shredding is sent into roll extrusion divide carry out the branch silk in the silk machine after, put into boiling container again, add water to the water surface and exceed 10 millimeters of bamboo chips, boiling under 1 atmospheric condition; The purpose of boiling is to remove materials such as lignin, sugar, fat, albumen, starch, makes phenomenon and softnesses such as bamboo fibre is difficult for going mouldy, infested; Another utility model patent equipment " the roll extrusion burst divides the silk machine " that roll extrusion divides the silk machine can adopt the applicant, its purpose is that the bamboo fibre extraction is prepared, certainly manual hammering or the similar manual machinery of beating can realize that also roll extrusion divides the silk purpose, and the bamboo fibre on the bamboo chip of roll extrusion branch silk back is thread arrangement.

D, fiber extract: the bamboo chip of expanded metals shape is sent into carried out the fiber extraction in the fiber extractor, obtain containing the bamboo fibre of impurity such as bamboo powder, bamboo head, bamboo stalk, tabasheer; The fiber extractor can adopt another utility model patent equipment " nail roller bamboo fibre extractor " of the applicant.

E, screening are dry: sieve with artificial hand-sort screening or mechanical system or streamer mode, obtain pure bamboo fibre after, place natural air drying under the sunlight, or carry out drying with drying room, drier, the water content to bamboo fibre is 3-30%; The mechanical system screening can be adopted another utility model patent equipment " pendulum-type grading oscillating screen " of the applicant.Dry employed thermal source can be coal, electricity, oil, hot blast, hot water, steam etc.; According to circumstances simultaneously, artificial hand-sort screening, mechanical grading mode and airflow screening mode can supportingly be used better effects if.The purpose of screening is to remove not by the tubbiness bamboo fibre of shredding fully, bamboo powder, ring, bamboo stalk etc., obtains to meet the fiber of bamboo fibre standard-required, and the qualified bamboo fibre after the screening will prevent to pollute, as sneaks into impurity such as iron nail, stone, sand grains.

F, packaging and warehousing: to pressure packing after the product inspection, the rectangle Fibre Bag that is packaged into every bag of 20～25Kg on baling press is dressed up product.
