Abstract

The invention discloses a manufacturing method of a bamboo fiber molding type product. The manufacturing method comprises the steps of: machining bamboo fibers through a machining process of accurate grinding, dissolving, vacuum-absorbing and shaping; enabling the fibers to take on brooming to the maximum extent by accurately grinding and hydraulically stirring the bamboo fibers for 30-50 min based on characteristics that the fibers of the bamboo fibers are long and thick, but not soft enough; and then enabling a surface of a finished product to be smooth and beautiful like a ceramic through vacuum absorption of moisture and high-temperature instant shaping. The manufacturing method of the bamboo fiber molding type product realizes 60-70% high-purity machining of the bamboo fibers, not only can realize green production of the bamboo fiber products, but also can be satisfied with requirements on production of environment-friendly tableware and packaging containers as the bamboo fibers obtained through the manufacturing method can be satisfied with the requirements on the bamboo fibers needed for the environment-friendly tableware.

Description

Bamboo fibrid moulding type article fabrication methods

Technical field

The preparation method of a kind of moulding article bamboo of the present invention fibrid belongs to be particularly related to and produces environment protecting tableware and the used bamboo fiber material of packing container moulding type article fabrication methods.

Background technology

Present environment protecting tableware and packing container process by alloy, pottery and plain paper, and right such material makes its cost of goods manufactured high, are unfavorable for the unfavorable phenomenons such as environmental protection and easy germ contamination;

Existing bamboo fibrid has good gas permeability, moment water imbibition, stronger ABRASION RESISTANCE and the good characteristics such as dyeability, have again simultaneously natural antibacterial, antibacterial, except mite, deodorization and anti-ultraviolet function.And bamboo fibrid in the market has following two classes: the one, and the regenerated fiber with bamboo pulp is produced is commonly referred to bamboo pulp fiber; The 2nd, the fiber that directly from bamboo, extracts through special process.China is in the existing many patents of invention of bamboo fiber manufacture method in recent years, CN11078520C has announced a kind of manufacture method, CN1261290C that former bamboo is opened bar, kicker, formation bamboo fibrid bundle goods and has announced a kind of method that former bamboo bamboo chip is adopted pure physics, by the boiling sub-wire, desaccharification, degrease, after protein, starch are processed, through mechanical impact, tear, shredding well-thought-out plan fibrid.Yet the said method production step, but in the above-mentioned several different methods, the impurity content of the bamboo fibrid of its complex process and extraction is high, and then be unfavorable for producing.

Summary of the invention

Purpose of the present invention is to overcome the deficiency that exists in the background technology, for proposing to replace with the bamboo fibrid material of original tableware and packing container, therefore it provides the bamboo fibrid moulding type that a kind of bamboo fibrid dna purity is high, productivity effect is high article fabrication methods.

For achieving the above object, the present invention adopts following scheme:

A kind of bamboo fibrid moulding type article fabrication methods, comprise the steps: correct grinding: bamboo class bamboo fibrid directly enters hot grinder and carries out mechanical lapping, makes the fiber fracture destroy the destruction of the inner hydrogen bond of cellulose; Dissolving: the bamboo fibrid after will grinding is dissolved in organic solvent and carries out hydraulic mixing formation fiber pulp, and the bamboo fibrid is unfolded fully; Vacuum suction: fiber pulp is absorbed water by vavuum pump, and the bamboo fibrid after the suction is adsorbed on the net mould; Typing: the net mould is placed in the setting machine, finalizes the design by High Temperature High Pressure.

For perfect scheme, in the above-mentioned bamboo fibrid moulding type article fabrication methods, in step a, the bamboo fibrid is the 110-125 degree at the hot grinding temperature of hot grinder, and its correct grinding time at hot grinder is 20-30 minute.

For perfect scheme, in step c, after the suction of bamboo fibrid, by putting into the also lower pressure network mould of net mould the bamboo fibrid is adsorbed on the net mould.

For perfect scheme, in step b, make bamboo fibrid generation brooming, keep simultaneously the TENSILE STRENGTH of fiber to remain on 2.5-2.8cN/dtex, and be 60-70% through the fiber content after purifying, and described organic solvent is ethanolic solution.

For perfect scheme, in step c, its vavuum pump pressure that is that absorbs water is 3.5-4.5KG.

The present invention's beneficial effect compared to existing technology is: pass through said method, realized the 60-70% high-purity processing of bamboo fibrid, and can satisfy the requirement of the required bamboo fibrid of environment protecting tableware by the bamboo fibrid that obtains, not only can realize the green production of bamboo fibrid preparation, satisfy simultaneously the requirement that environment protecting tableware and packing container are produced, simultaneously its processing method is simple, makes as the finished surface pottery smoothly, attractive in appearance in typing processing, and then has improved its end product quality.

The specific embodiment

The invention will be further described below in conjunction with drawings and Examples:

In order to guarantee its stability, be that the bamboo fibrid can fully finish grind, in step a, the bamboo fibrid is the 110-125 degree at the hot grinding temperature of hot grinder, and its correct grinding time at hot grinder is 20-30 minute.

In order to make its amount that guarantees its absorption, in step c, after the suction of bamboo fibrid, by putting into the also lower pressure network mould of net mould the bamboo fibrid is adsorbed on the net mould.

The invention will be further described below in conjunction with embodiment:

In order to guarantee the effect of its vacuum dehydration, guarantee the purity of bamboo fibrid, in step c, its vavuum pump pressure that is that absorbs water is 3.5-4.5KG

It is long, thick that the bamboo fibrid has fiber, soft not characteristic, by with the bamboo fibrid by correct grinding, hydraulic mixing 30-50 minute, make fiber present farthest " brooming ", again by " vacuum moisture absorption ", high temperature moment finalize the design make as finished surface such as the pottery smooth, attractive in appearance.

The above only is preferred embodiment of the present invention, not take the present embodiment as restriction, all any modifications of making within the spirit and principles in the present invention, is equal to and replaces or improvement etc., all should be included within protection scope of the present invention.
