Description
Technical field
The invention relates to the manufacture method of a kind of environment protecting tableware or container, but refer to a kind of natural decomposition of a kind of energy manufacturing especially, and the manufacture method of environment protecting tableware with low cost or container.
Background technology
At present, many deserted, once tableware disposable after use or container uses in daily life widely, they can be abandoned after using, to reach convenient, to save trouble and the timesaving effect.Use and be used as disposable utensils that bowl, plate, cup etc. use or container more mass society is popular.Yet, this kind disposable utensils or container are normally made by the plastic cement of for example Poly dragon, polypropylene, polyester foamed plastics etc., its processing after using has many defectives, major defect is exactly the decomposition that the disposable tool of this kind or container can't natures, therefore accumulation is many more more, cause serious environmental issue, and in the time need being handled, as through the heating or the burning, then can produce toxic gas, further cause the pollution of air, and it is uncomfortable that human body is taken place, extremely influence environmental protection and people's health.For today of emphasizing environmental consciousness, these disposable utensils or container are considered as the public enemy by people, and gradually cast aside, existing multinational legislation forbidding is with these materials made disposable utensils or container or relative article in countries in the world, China also has relevant organization just promoting legislation, believe soon in the future, with the made disposable utensils of these materials or container or relative article in domestic also with disabled, because of this is a trend of the times.
Therefore, but dealer or government's associated mechanisms all are devoted to develop the tableware or the container of natural decomposition in recent years, to meet environmental protection requirement, and the descendants that brings benefit to the next generation, for example paper tableware or container or with the starch of corresponding plants made tableware or container are the disposable utensils or the container of material with plastic cement or Poly dragon in the hope of substituting aforementioned fully.It is raw material that this kind paper tableware or container are to use paper, only paper is made by timber, paper pulp etc., it is to stem from trees, and because growing up to of trees is quite consuming time, and limited amount, problem (influence water and soil conservation, and then cause disaster) of existing very serious forest estrepement, so this kind paper tableware at present or container still are not a kind of preferably selections of making the material source of disposable utensils or container.And starch dishware or container are to utilize the material that contains starch based content in the cereals of nature, for example wheat, rice etc. are raw material, through foaming process in addition after the expansion process, bonding and get with paper again, but because it is to use edible cereal such as wheat, rice to be used as raw material, except the suitable costliness of manufacturing cost, and make us unavoidably feeling to waste natural products (as application number be: 80107265,74103826 and append patent cases such as case), it very is the waste resource, therefore these materials can not be used for making disposable utensils or container widely.So, as Japanese publication 6-259384 patent case, United States Patent (USP) the 5th, 500, No. 089 and Taiwan apply for that No. 82104019 patent case etc. all discloses the manufacture method of a kind of environment protecting tableware or container, in the hope of making a kind of environment protecting tableware or container that can solve serious day by day environmental issue.
Manufacture method by this Japanese publication 6-259384 patent includes the following step:
(1) cereal duricrust (husks) is milled to powdery or graininess;
(2) the cereal duricrust with step (1) is mixed with laccol coating (cashew paint);
(3) mixture with step (2) is placed in the mould, then at the HTHP compacted under; And
(4) underwater paint is coated on the surface of the in type tableware of step (3) or container.
Yet, the manufacture method that this Japanese publication 6-259384 patent case is disclosed does not disclose and defines the mixed proportion relation between cereal duricrust and the laccol coating clearly, make cereal duricrust and laccol coating can may cause the indefinite of tableware or container quality because of the change of content and change, thereby have only the fraction defective that increases product, and can cause the increase of manufacturing cost.
Moreover, as United States Patent (USP) the 5th, 500, though the manufacture method that No. 089 it disclosed includes many steps, but the condition and the ratio of itself and incomplete exposure correlation step and constituent, two steps in the step are only mentioned respectively dry pars fibrosa (fibersections) are added in the gelatinized corn starch (starch paste) that contains water as described in it, then pars fibrosa is mixed fully with gelatinized corn starch, do not define pars fibrosa clearly but study carefully, mixed proportion relation between gelatinized corn starch and the water, therefore see it with the angle of implementing, as if its technology indeterminate, and the difficult possibility that reaches enforcement, vertical or implemented, so fail to understand because of ratio, also may be because of pars fibrosa, gelatinized corn starch and water content be because of the change of ratio, and cause the change of tableware or container quality, thereby increase the fraction defective of product, and then cause the increase of manufacturing cost.
And the described manufacture method of patent case is applied in Taiwan No. 82104019, though also mention some steps, relevant condition, ratio and technology are also failed in its specification one by one exposure; By its processing procedure mainly is to draw materials from having the natural plants that obvious strip divides bundle fiber, then the organic property fiber in this plant being blocked becomes the short fiber shape and had both done broken diffusing processing, again short fiber is dropped in the starch heap, through doing fully, stirring uniformly, and cooperate the gelatinization of starch to handle, both are allocated under the condition of a geometric ratio or specific multiple proportions mix.Yet, though this method has exposure a little to the proportionate relationship of short fiber and starch, but look into, the obvious strip of tool to be divided organic property fiber in the natural plants of bundle fiber to block to become program that the short fiber shape both done broken diffusing processing difficulty considerably, because when strip being divided bundle fiber block into the short fiber shape, the phenomenon that strip divides bundle fiber very easily to tear because of the effect of external force, perhaps when blocking, also easily float because of light weight, and can't block into the short fiber shape fully, when stirring with starch and water again, then can be entangled with into bulk, make quality wayward.Moreover short fiber and starch to be stirred, real in being difficult for, because of before not adding water, above fluffy fiber must maintain, starch oneself can't with its sufficient mixing; And after adding entry, if water shortage, both are easier to be entangled with into mutually bulk, can make the difficulty that takes place of feed separation and feed operation procedure inevitably, and can't reach continuous and a large amount of production.And when increasing the water yield, though convenient the stirring, follow-up dehydration and drying program are suitable consuming time, and if excessive dehydration, not carrying on a shoulder pole increases flow process and cost, also can make product generation crack performance itself, causes the bad flaw of quality; And a large amount of waters is not only wasted resource, and can increase manufacturing cost, and more the discharging of person's waste water also can cause environmental issue.
Aforementioned again all do not disclose in the case before all its when producing the equipment or the device that should use, therefore technological means is indeterminate, moreover the big person of these cases directly pours into mixed raw material in the so-called forming mould, can't produce in a large number first, then uncontrollable its product thickness in addition, and will influence quality, in addition, with regard to economic benefit, only cause the raising of cost, will increase burden to the user.
Edge this, the inventor is implementing and is carrying out that thoughts on the manufacture method of commonly using environment protecting tableware or container many disappearances are still arranged, be that the spy concentrates on studies, and cooperate application academic and scientific principle, propose a kind of reasonable in design and can effectively improve the manufacture method of the environment protecting tableware or the container of above-mentioned disappearance finally.
