Abstract

PURPOSE:To prevent possible environmental pollution with sufficient deodorizing power by granular solids of bamboo dried is molded by pressure compression and porous parts of the granular solids are exposed to an ambient atmosphere without being blocked by a synthetic resin or the like to make smelling components adsorb on the porous parts. CONSTITUTION:Dried dry granular solids 1 with an average particle size of about 0.1-6.0mm produced by drying chips of bamboo to be discarded and burned as waste are packed into a lower die 3 of a press molding apparatus 2 and a specified amount thereof is measured. Then, the upper die 4 is pressed down onto a lower die 3 to compress the material by a pressure of 1-5ton/cm<2>. After the compression, the material is taken out of the press molding apparatus 2 to obtain a deodorizing molded product. The porous part of the deodorizing molding is exposed to an ambient atmosphere without being blocked by a synthetic resin or the like to make smelling components adsorb on the porous parts. When the deodorizing effect reduces with the prolonged use thereof, the deodorizing molding can restore the deodorizing effect thereof by exposing it to the sun shine for a while.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a deodorized molded article.

[0002]

2. Description of the Related Art Conventionally, as a method for deodorizing putrid odors such as organic substances, cigarette odors and other household goods, a fragrance using natural or artificial fragrances or a deodorant using activated carbon which is a porous substance is used. Deodorizing is done.

[0003]

By the way, the fragrance is
Since some components are harmful to the human body, they may be problematic when used in daily necessities such as clothing and food. On the other hand, activated carbon is produced by carbonizing raw materials such as wood, palm shell, and liquefied petroleum gas, and further activated by steam and chemicals, and is relatively harmless to the human body, Since most of the raw materials are imported, there is a problem that the manufacturing cost increases.

Since activated carbon is granular, it is usually packed in a breathable bag before use. Therefore, there is a problem that the capacity cannot be easily adjusted according to the space for deodorizing. Therefore, in order to solve such a problem, the present applicants have prepared a deodorized molded product obtained by solidifying dry-distilled bamboo powder and granules (hereinafter referred to as “dry-distilled powder and granules”) with a synthetic resin (Japanese Patent Application No. No. 3-316348) has been previously proposed.

According to this deodorized molded product, it is possible to use the scraps of bamboo that have been discarded and incinerated as a waste material, which leads to environmental protection and can reduce the manufacturing cost. Moreover, if it is formed into a tablet shape, it has the advantage that the amount used can be freely adjusted according to the space for deodorization. However, the deodorized molded product has a problem that the deodorizing ability of the dry-distilled powder is hindered by the synthetic resin because the dry-distilled powder is solidified with the synthetic resin.

In view of such circumstances, it is an object of the present invention to provide a deodorant molded article which can exhibit a sufficient deodorizing ability.

[0007]

In order to achieve such an object, the deodorized molded article according to the present invention is obtained by press-molding a dry-distilled powder into a desired shape. In the above structure, the particle size of the dry-distilled powder is not particularly limited, but it is 0.1 to 0.1 in average particle size.
It is preferably about 6.0 mm (particularly 0.5 to 4 mm).

When molding is carried out, the pressure applied is preferably 1 to 5 ton / cm ² , particularly preferably 3 ton / cm ² .

The raw material bamboo is not particularly limited, but Meng bamboo is preferable. The molding temperature and humidity are not particularly limited, but may be normal temperature and normal humidity. Further, the deodorized molded article is not particularly limited, but for example, a refrigerator, a kitchen or an underfloor storage part, a microwave oven or a gas stove when not in use, a kitchen corner of a triangular corner of a sink, a drawer, a closet, It can be used in a kotatsu, in a box, inside shoes and bags when not in use, in a cooler box for fishing, in a car, pots and planters for foliage plants, etc.

[0010]

According to the above construction, since the dry-distilled powder and granules are solidified and molded only by compression under pressure, the porous portion of the powder and granules is exposed to the surrounding atmosphere without being disturbed by the synthetic resin or the like, and the odor is eliminated. The components are adsorbed on the porous part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings showing the embodiments thereof. FIG. 1 shows one embodiment of a method for producing a deodorized molded article according to the present invention in the order of steps. That is, as shown in FIG. 1 (a), first, the dry-distilled powder granules 1 are filled in the lower mold 3 of the press molding machine 2,
A predetermined amount is measured as shown in FIG. Then, as shown in FIG. 1C, the upper mold 4 is pushed down to the lower mold 3 side, compressed at a predetermined pressure, and then taken out from the press molding machine 2 as shown in FIG. Can be obtained.

(Example 1) Using a commercially available dry-distilled powder (manufactured by Takezumi Sangyo Co., Ltd., trade name "Kiyora" having an average particle size of 4 mm or less), as shown in FIG. ₁ = about 2
cm, L ₂ = about 0.5 cm, L ₃ = about 2.5 mm, and a weight of 1 g of a tablet-shaped deodorant molded product 5 was obtained. 30% of this deodorized molded body 5
As shown in FIG. 3, the particles are stored in the closed chamber 6 with the microsyringe 7 into the closed chamber 6,
Ammonia gas with a concentration of 85 ppm was injected, and the ammonia gas concentration in the closed chamber 6 was detected with time using a detector tube (north gas detector tube: manufactured by Komei Rigaku Kogyo Co., Ltd.) 8.
The removal rate of ammonia gas from the deodorized molded body 5 was examined.

Example 2 The removal rate of ammonia gas from the deodorized molded article 5 was examined in the same manner as in Example 1 except that the concentration of the injected ammonia gas was 112 ppm.

Comparative Example 1 Commercially available dry-distilled powder (manufactured by Takezumi Sangyo Co., Ltd., trade name "Kiyora" having an average particle size of 4 mm or less) and a polyester resin were mixed at a weight ratio of 4: 1. The molded product as shown in Fig. 5 is molded and the weight of the dry-distilled powder is 3
The molded body was housed in the closed chamber 6 so that the weight became 0 g, and the ammonia gas removal rate of the molded body was examined in the same manner as in Example 1.

Table 1 shows the time-dependent removal rates of ammonia gas examined in Examples 1 and 2 and Comparative Example 1.

[0016]

[Table 1]

As is apparent from Table 1 above, the deodorized molded product of the present invention is molded entirely from dry-distilled powder granules, so that the gas removal rate is very good. In addition, when the deodorizing effect of the deodorizing molded article according to the present invention was reduced over a long period of time, the deodorizing effect could be restored by exposing it to the sun for a while.

[0018]

EFFECTS OF THE INVENTION Since the deodorized molded article according to the present invention is constructed as described above, it is possible to use the scraps of bamboo that have been discarded and incinerated as a waste material, which leads to environmental protection and reduces the manufacturing cost. It can be reduced. Moreover, if it is formed into a tablet shape, it has the advantage that the amount used can be freely adjusted according to the space for deodorization.

Further, since it is formed only from dry-distilled powder and granules, the gas removal rate is very good and a sufficient deodorizing ability can be exhibited. Further, since it is formed only by dry-distilled bamboo powder and granules, even if it is no longer needed, it can be completely assimilated with soil by burying it in the soil, without causing environmental pollution.
