Description
本発明は陶磁器産業において、主原料に瓶ガラス及びそのカレット及び廃棄瓶ガラスを用いた陶磁器粘土に関する。 In the ceramic industry, the present invention relates to ceramic clay using bottle glass and its cullet and waste bottle glass as main raw materials.
一般的な陶磁器は粘土鉱物、珪石、長石等を用途に合わせて調製、水と共に混合粉砕を行ない、脱水、成形、乾燥、素焼焼成、顔料を下絵付け、釉薬を施した後、本焼成を行い製品としている。素焼き行程を省いたり、下絵行程が無い場合、釉薬を施さない場合もあるが、更に釉薬にて上絵付けを施して再度低温焼成を行う場合もある。 For general ceramics, clay minerals, quartzite, feldspar, etc. are prepared according to the application, mixed and pulverized with water, dehydrated, molded, dried, unglazed, painted with a pigment, applied with glaze, and then fired. It is a product. If the unglazed process is omitted or there is no sketch process, the glaze may not be applied, but it may be further subjected to low temperature baking after further painting with a glaze.
陶磁器の製造コストには各行程に掛かる設備費、原材料費や人件費等が必要であるが、焼成費の占める割合も大きい。陶磁器業界からは省力化及び焼成コスト削減の為に焼成温度を下げる技術革新が期待されている。 The production cost of ceramics requires equipment costs, raw material costs, labor costs, etc. for each process, but the proportion of firing costs is also large. From the ceramic industry, technological innovation is expected to lower the firing temperature in order to save labor and reduce firing costs.
焼成コスト削減を目的として白雲磁器が開発された。画期的な発明であるが、機械的強度においてやや劣る事が難点である。フリット磁器も研究されたが、価格が割高な事と焼成時の変形に難点がある。 Baiyun porcelain was developed to reduce the firing cost. Although it is an epoch-making invention, it is difficult to be slightly inferior in mechanical strength. Frit porcelain has also been studied, but it is expensive and has problems with deformation during firing.
低温焼成を目標に、これまでフリット或いは廃棄ガラスを主原料に使用した陶磁器粘土の試作が試みられたが、焼成時に軟化変形を生じていた。非晶質のガラスを主原料に使用する以上、避けては通れない課題であるが、焼成時に形状維持に有効な骨材が変形を防ぐ事も予想されていた。 Attempts were made to produce ceramic clay using frit or waste glass as the main raw material with the goal of low-temperature firing, but softening deformation occurred during firing. As long as amorphous glass is used as the main raw material, it is a problem that cannot be avoided, but it has also been expected that an aggregate effective for maintaining the shape during firing will prevent deformation.
園芸用植木鉢、赤煉瓦、透水タイル等、適度な吸水性及び透水性を要求される陶器には低温焼成に適した仕様の素地が使用してあるが、花瓶等の花器、茶碗や急須等の食器など遮水性を要求される陶磁器の製造には向かない。 For pottery that requires moderate water absorption and water permeability, such as flowerpots for gardening, red bricks, water permeable tiles, etc., materials with specifications suitable for low-temperature firing are used, but vases such as vases, tea bowls, teapots, etc. It is not suitable for the production of ceramics that require water-blocking, such as tableware.
一般的な陶磁器粘土には珪素、アルミニウム、カルシウム、マグネシウム、ナトリウム、カリウム等の酸化物が含まれるが、これは通常のガラスにも含まれている成分である。従って、廃棄ガラスは陶磁器原料代替品として使用出来る可能性がある。これまでにも廃棄ガラスを陶磁器粘土に添加して焼成温度を下げる試みが成されており、透水タイル等の舗装材及び建材等として積極的に利用されている。 Common ceramic clay contains oxides such as silicon, aluminum, calcium, magnesium, sodium, and potassium, which are components contained in ordinary glass. Therefore, there is a possibility that waste glass can be used as a substitute for ceramic materials. Attempts have been made to lower the firing temperature by adding waste glass to ceramic clay, and it has been actively used as paving materials such as permeable tiles and building materials.
焼成温度を下げる事により焼成コストを削減出来る陶磁器粘土製造方法の提供。 Providing a ceramic clay manufacturing method that can reduce the firing cost by lowering the firing temperature.
瓶ガラス及びそのカレット及び廃棄瓶ガラスを陶磁器粘土の主原料として有効利用する方法の提供。 Providing a method for effectively using bottle glass and its cullet and waste bottle glass as the main raw material of ceramic clay.
瓶ガラス及びそのカレット及び廃棄瓶ガラスを主原料に使用して、なおかつ焼成時の変形を防ぐ骨材を有する陶磁器粘土製造方法の提供。 A method for producing ceramic clay using a bottle glass, its cullet and waste bottle glass as a main raw material, and having an aggregate which prevents deformation during firing.
ガラス質の原料を多用する素地では焼成時に変形するので、骨材として焼成粘土粉あるいは請求項３の陶磁器粘土焼成品を添加する事により解決した。骨材として他の陶磁器原料にて試験を試みたが効果は明確に現れなかった。粘土鉱物にはカオリン族、モンモリロナイト族、イライト族等を使用する事が出来るが、焼成粘土粉と未焼成の粘土鉱物には同じ粘土鉱物を使用する必要は無い。 Since the substrate that uses a lot of glassy material is deformed at the time of firing, the problem was solved by adding a fired clay powder or a ceramic clay fired product of claim 3 as an aggregate. Tests were conducted with other ceramic materials as aggregates, but the effect was not clearly shown. Kaolin group, montmorillonite group, illite group, etc. can be used as the clay mineral, but it is not necessary to use the same clay mineral for the fired clay powder and the unfired clay mineral.
粘土鉱物を焼成して焼成粘土粉にするのであるが、焼成する際の温度は骨材効果及び成形時の手触りに影響を及ぼした。粘土鉱物の種類により異なるが、焼成温度が７５０度以下では骨材効果が少なく、１２００度以上では成形時の手触りの感触が悪くなった。粘土鉱物を７５０〜１２００度の範囲で焼成すると、未焼成時に含まれていた有機物が燃焼する事、物理吸着水や水酸化物が無くなる事、不純物や粘土内に含まれるナトリウム、カリウム等が溶融材となり粘性を生ずる結晶構造の一部を浸食するものの粘土としての特性を残している状態である為と推測される。骨材効果と成形の際の触感の両立のために粘土鉱物は７５０度以上１２００度以下にて焼成する必要がある。同様の理由により焼成陶磁器粉について７５０〜１１００度焼成物が骨材効果に有効であると推測される。 The clay mineral is baked into a baked clay powder, but the temperature at the time of calcination affected the aggregate effect and the feel during molding. Although it varies depending on the type of clay mineral, the aggregate effect is low when the firing temperature is 750 ° C. or less, and the feel of the hand during molding is poor at 1200 ° C. or more. When clay mineral is baked in the range of 750 to 1200 degrees, the organic matter contained in the unfired burns, the physical adsorption water and hydroxide disappear, impurities and sodium, potassium, etc. contained in the clay melt. This is presumed to be due to the fact that the material remains as a clay, although it erodes part of the crystal structure that becomes a material and produces viscosity. In order to achieve both the aggregate effect and the tactile sensation during molding, the clay mineral needs to be fired at 750 to 1200 degrees. For the same reason, it is presumed that a fired product of 750 to 1100 degrees is effective for the aggregate effect for the sintered ceramic powder.
焼成粘度粉及び焼成陶磁器粉は骨材として５〜３０重量％の添加を必要とした。５重量％以下では明確な効果は無かった。３０重量％以上の添加は焼成温度を上げる事になり、低温焼成の組成には適さなかった。 The fired viscous powder and the fired ceramic powder required addition of 5 to 30% by weight as an aggregate. There was no clear effect below 5% by weight. Addition of 30% by weight or more increases the firing temperature, and is not suitable for a composition for low temperature firing.
請求項２で使用する陶磁器用フリットは使用する瓶ガラス組成より硼素・リチウム・ナトリウム・カリウム・バリウム等の成分の多いものを用意すると組成調整及び焼成温度調整が容易である。この際、目的に合わせて組成調製したフリットを用意した方が良いのであるが、陶磁器用の汎用フリットを利用した方が安価で安定しいる。 The ceramic frit used in claim 2 can be easily adjusted in composition and firing temperature if a ceramic frit having more components such as boron, lithium, sodium, potassium, and barium than the bottle glass composition used is prepared. At this time, it is better to prepare a frit whose composition is adjusted according to the purpose, but it is cheaper and more stable to use a general-purpose frit for ceramics.
瓶ガラスのカレット及び廃棄瓶ガラスを有効利用する事で廃棄物の低減、資源の有効活用に貢献出来る。 Effective use of bottle glass cullet and waste bottle glass can contribute to the reduction of waste and the effective use of resources.
瓶ガラスを積極的に利用する事で、陶磁器粘土の低温焼成による熱エネルギー節約に貢献出来る。 By actively using bottle glass, it is possible to contribute to saving thermal energy by low-temperature firing of ceramic clay.
用途により多様な組成成分の瓶ガラスが存在するので、出来る範囲で分別した方が良い。瓶の色分けも品質の管理には有効である。多種多様な瓶ガラスを選別する事無く混合・縮分して、請求項１の範囲にて先行試験する方法もあるが、極端に異なる性質のガラス混合物は先行試験の再現性が乏しい。縮分しても少量の試験試料では組成変動があると推察され、極端に軟化点の異なるガラス混合物は焼成時の反応点が不確定であると考えられる。 Since there are bottle glasses with various composition components depending on the application, it is better to separate them as much as possible. Bottle color coding is also effective for quality control. There is also a method in which a variety of bottle glasses are mixed and shrunk without sorting, and a preliminary test is performed within the scope of claim 1. However, glass mixtures having extremely different properties have poor reproducibility of the preliminary test. Even if it is shrunk, it is inferred that there is a composition variation in a small amount of test sample, and it is considered that the reaction point at the time of firing is uncertain for glass mixtures having extremely different softening points.
瓶ガラスカレットや廃棄瓶ガラスには内容物表示の紙ラベルや樹脂ラベル、樹脂蓋、金属蓋等の混入が予想される。陶磁器粘土の品質管理の為に可能な限り排除する必要がある。 The bottle glass cullet and the waste bottle glass are expected to be mixed with paper labels, resin labels, resin lids, metal lids, etc. for displaying contents. It is necessary to eliminate as much as possible for quality control of ceramic clay.
町内会の分別資源ゴミ回収の際に透明瓶ガラスを譲り受け、ラベル及び蓋を取り除き洗浄した上で粗砕する。縮分で得られた試料を請求項１の条件にて先行試験を行い、調合割合を決定した。瓶ガラス６０重量％、モンモリロナイト系粘土２０重量％、高島化学工業株式会社販売の焼成粘土、商品名・焼石を１０％、同じく高島化学工業株式会社製フリットＢ０２７を１０重量％、合計１００重量％に同重量の水道水を加え、アルミナボール使用のアルミナ質ボールミルにて粉砕、ＪＩＳ標準ふるい３２メッシュ全量通過する事を確認する。
フィルタープレス脱水装置にて脱水処理の後、手で成形を行う。自然乾燥した後、無鉛上絵付け用釉薬を施し、電気炉にて概ね１００度毎時間の昇温速度、７５０度１時間保持にて焼成する。吸水率０．３％程度の陶器の器を得た。When collecting garbage from the neighborhood association, collect the transparent bottle glass, remove the label and lid, clean it, and crush it. The sample obtained by the reduction was subjected to a prior test under the conditions of claim 1 to determine the blending ratio. 60% bottle glass, 20% montmorillonite clay, 10% calcined clay sold by Takashima Chemical Co., Ltd., trade name and calcined stone, 10% frit B027 manufactured by Takashima Chemical Co., Ltd., totaling 100% by weight Add tap water of the same weight, grind it in an alumina ball mill using alumina balls, and confirm that it passes through the entire 32 mesh of JIS standard sieve.
After dehydration with a filter press dehydrator, molding is performed by hand. After natural drying, a lead-free glaze is applied and baked in an electric furnace at a heating rate of approximately 100 degrees per hour and held at 750 degrees for 1 hour. A pottery bowl with a water absorption rate of about 0.3% was obtained.
商品名・上高地名産河童の涙という瓶ガラスカレットを粗砕する。縮分で得られた試料にて先行試験を行い、調合割合を決定した。瓶ガラスカレット５０重量％、高島化学工業株式会社販売の焼成粘土、商品名・焼石を１５重量％、蛙目粘度２０重量％、高島化学工業株式会社製フリットＢ０２７を５重量％、三河産カリ長石１０重量％、合計１００重量％に同重量の水道水を加え、天然石使用のトロンメルミル粉砕機にて粉砕混合する。ＪＩＳ標準ふるい３２メッシュ全量通過する事を確認して、石膏型にて鋳込み成形、乾燥、仕上げの上、７００度程度で素焼きを行う。楽焼き用釉薬を施し、ガス窯にて概ね１００度毎時間の昇温速度、１０５０度にて焼成して花瓶を制作した。水漏れのない陶器を製造出来る事を確認した。 Crush the bottle glass cullet called Tears of the product name Kamikochi famous Kappa. Prior tests were performed on samples obtained by reduction, and the blending ratio was determined. Bottle glass cullet 50% by weight, calcined clay sold by Takashima Chemical Co., Ltd., 15% by weight of brand name and calcined stone, viscosity of 20% by weight, 5% by weight of frit B027 manufactured by Takashima Chemical Co., Ltd., Mikawa potash feldspar 10% by weight, tap water of the same weight is added to a total of 100% by weight, and pulverized and mixed with a trommel mill using natural stone. After confirming that the entire JIS standard sieve 32 mesh has passed, cast-mold, dry, and finish with a plaster mold, and perform unglazed baking at about 700 degrees. A vase was produced by applying a glaze for easy baking and baking at a heating rate of approximately 100 degrees per hour in a gas kiln at 1050 degrees. It was confirmed that pottery without water leakage could be manufactured.
低温にて焼成可能なので、高温では分解する、あるいは低温での発色に優れている顔料及び釉薬が多用出来る。 Since it can be fired at a low temperature, a pigment and a glaze that decompose at a high temperature or are excellent in coloring at a low temperature can be used.
高温での焼成に比べ焼成炉の設備費が安価になり、焼成費用も下がる。 Compared with firing at a high temperature, the equipment cost of the firing furnace is reduced, and the firing cost is reduced.
ロット毎に組成変動のある瓶ガラスのカレット及び廃棄瓶ガラスを主原料にする事は、陶磁器粘土の安定供給を困難にするのであるが、近似した製品を安価に製造する事は可能である。調合組成決定の為に先行試験が必要であるが、掛かる経費を量産効果で回収出来れば産業として成り立つと考える。 Using cullet of glass bottles and composition of waste bottle glass whose composition varies from lot to lot as a main raw material makes it difficult to stably supply ceramic clay, but it is possible to produce an approximate product at low cost. A prior test is required to determine the composition of the composition, but if the cost can be recovered by mass production, it will be considered as an industry.
