Abstract
Description
本発明は、ガラスのミクロ相分離を利用して得られる多孔質ガラスを表面に被膜として施した陶磁器またはガラス容器に関するものである。 The present invention relates to a ceramic or glass container having a surface coated with porous glass obtained by utilizing microphase separation of glass.
従来、水の酸化還元電位を低下させる方法として、例えば特許文献１のような還元水用粒状セラミックスなどを直接水中に沈めて改質する手段が一般的である。
しかしながら、特許文献１のようなセラミックスでは限られた容量の水と接触する面積には限界があり、セラミックスを多くすると本来利用目的の水容量が小さくなり、少ないセラミックスで大量の水を改質するとなると長時間を要するなど手軽に水改質することに対しては難しい。例えば、飲料用容器内に注いだ液体が、時間をかけなくても直ぐに改質されるためには、液体との豊富な接触面積が必要である。 However, in ceramics such as Patent Document 1, there is a limit to the area that comes into contact with a limited amount of water, and when the amount of ceramics is increased, the water capacity originally intended for use is reduced, and when a large amount of water is modified with less ceramics. Then, it is difficult for water reforming easily because it takes a long time. For example, in order for a liquid poured into a beverage container to be immediately modified without taking time, an abundant contact area with the liquid is required.
本発明は、従来技術の問題点に鑑みて鋭意研究を重ねた結果、液体との豊富な接触面積が期待できるガラスの相分離を利用した多孔質ガラス皮膜を表面に施した陶磁器またはガラス容器を形成することを見出した。 As a result of intensive research in view of the problems of the prior art, the present invention provides a ceramic or glass container having a porous glass film on the surface utilizing phase separation of glass that can be expected to have abundant contact area with liquid. Found to form.
本発明によると、容器内に水を注いだ直後から水改質が起こり、その豊富な表面積を有するシラノール基との接触効果により、例えば、飲料用の器などに形成すると水をまろやかに改質することができる。 According to the present invention, water reforming occurs immediately after pouring water into the container, and due to the contact effect with the silanol group having abundant surface area, for example, when it is formed in a beverage container, the water is gently reformed. can do.

［実験例１］
図１（ｄ）に示す本発明に係る基材容器１内面の底部に前記SPG被膜を形成した約100cc容の陶器に関し、蒸留水を注いだ直後の酸化還元電位を経時的に計測した。本発明に係る基材容器１内面の底部に前記SPG被膜を形成した約100cc容の陶器５検体に注いだ蒸留水は、それぞれ表１中「Ａ」、「Ｂ」、「Ｃ」、「Ｄ」、「Ｅ」の５検体で、比較対象として、SPG被膜を形成していないそのままの同類陶器に注いだ蒸留水（表１中「原水」）、底部が埋まる程度にSPG破片を投入した１００ｃｃ容プラスチック容器に注いだ蒸留水（表１中「SPG破片」）、底部が埋まる程度に外径３ｍｍ×内径２ｍｍ×長さ４ｍｍのＳＰＧビーズを投入した１００ｃｃ容プラスチック容器に注いだ蒸留水（表１中「ＳＰＧビーズ大」）である。ここで、本実施例で形成したＳＰＧ被膜の微細孔は、１μｍ以下である。
[Experimental Example 1]
The oxidation-reduction potential immediately after pouring distilled water was measured over time for an approximately 100 cc pottery having the SPG film formed on the inner surface of the base material container 1 according to the present invention shown in FIG. Distilled water poured into approximately 100 cc pottery specimens having the SPG film formed on the bottom of the inner surface of the base material container 1 according to the present invention is “A”, “B”, “C”, “D” in Table 1, respectively. ”,“ E ”, 100 cc of distilled water (Table 1“ raw water ”) poured into a similar pottery without an SPG film, and SPG fragments to the extent that the bottom is filled. Distilled water poured into a plastic container (“SPG fragment” in Table 1), distilled water poured into a 100 cc plastic container filled with SPG beads with an outer diameter of 3 mm, an inner diameter of 2 mm and a length of 4 mm to fill the bottom (Table 1 is “large SPG beads”). Here, the micropores of the SPG film formed in this example are 1 μm or less.
このように、本発明に係る容器によると、水道水など原液そのものの酸化還元電位が５００ｍＶなど高い数値の水溶液を、−２００ｍＶ程度下げることができる。 Thus, according to the container of the present invention, an aqueous solution having a high numerical value such as a redox potential of 500 mV of the stock solution itself such as tap water can be lowered by about -200 mV.
本発明のガラスの相分離を利用して得られる多孔質ガラス被膜を形成した陶磁器またはガラス容器は、現在の一般に酸化還元電位が５００ｍＶ以上といわれる水道水社会において手軽に酸化還元電位を下げることのできる容器として利用することができる。飲用する水やアルコール類、水割り用水、生け花、植物水栽、プランター、観賞魚などあらゆる場面で使用される酸化還元電位の高値な水道水を生体環境に良い酸化還元電位の低値な水として供給させることができる。酸化還元電位の高値な水は生体を酸化させてしまい老化の原因にもなる。このように本発明に係る容器の形態を、陶磁器やガラス製などの飲料用容器や水差し、かめ、花瓶など種々の基材に合わせて多孔質ガラス被膜を形成することが可能で、より酸化還元電位の低い水を手軽に提供することができる。 The ceramic or glass container formed with the porous glass film obtained by utilizing the phase separation of the glass of the present invention can easily lower the redox potential in a tap water society where the current redox potential is generally said to be 500 mV or more. It can be used as a container that can be used. Supply tap water with a high oxidation-reduction potential used in various situations such as drinking water, alcohol, water splitting, ikebana, plant water planting, planters, ornamental fish, etc., as water with a low oxidation-reduction potential that is good for the living environment Can be made. Water with a high oxidation-reduction potential oxidizes the living body and causes aging. In this way, it is possible to form a porous glass film according to various base materials such as pottery containers, water bottles, turtles, vases, etc., in the form of containers according to the present invention. Water with low potential can be easily provided.
