本発明は自己施釉セラミック材料の製造法に関し、特に
湿式成形後の片面乾燥（こよって片面のみ光沢のあるこ
とを特徴とする自己施釉セラミック材料の製造法に関す
る〇
従来、自己施釉セラミック材料は長石等を加えそのアル
カリ分の溶融によってガラスを生威し、光沢を得るもの
であったが、焼成の際、溶融ガラス生成のため、製品と
焼成台板とが付着しやすい欠点があった。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a self-glazing ceramic material, and in particular to a method for producing a self-glazing ceramic material characterized by drying on one side after wet forming (thereby being glossy on only one side). Self-glazing ceramic materials were made by adding feldspar etc. and melting the alkaline content to create glass and obtain gloss, but since molten glass is produced during firing, the product and the firing plate tend to stick together. There were drawbacks.
ところで自己施釉セラミックは、成形直後、物質内部で
均一に分布している水溶性アルカリ分が水分の乾燥にと
もなって表面で高濃度となることによって光沢を得る。Immediately after molding, self-glazing ceramics acquire luster because the water-soluble alkaline content uniformly distributed inside the material becomes highly concentrated on the surface as the water dries.
一般に自己施釉セラミック材料は湿式成形で賦形され、
次で自然乾燥されるのであるが、本発明者の研究による
と、乾燥速度の差により自己施釉が生じない焼成品を得
ることができることが分った。Generally, self-glazed ceramic materials are shaped by wet molding,
According to research conducted by the present inventors, it has been found that due to the difference in drying speed, it is possible to obtain a fired product that does not self-glaze.
そこで本発明では乾燥速度を湿式成形品の各部に対゛し
て変化させることにより、焼成台板への焼成品の付着を
防止させる方法を開発した。Therefore, in the present invention, a method has been developed to prevent the fired product from adhering to the firing base plate by varying the drying rate for each part of the wet molded product.
即ち、本発明は自己施釉セラミック材の出発原料の湿式
成形品のうち、少くとも焼成台板に接触する個所及びそ
の近傍にすなわち乾燥防止手段を施し、そして成形品を
自然乾燥し、次で焼成台板に載せて焼成することＩこよ
り、合板への付着のない自己施釉セラミック材料を得る
ものである。That is, in the present invention, a drying prevention means is applied to at least a portion of a wet molded product of a starting material of a self-glazed ceramic material that contacts a firing base plate and its vicinity, and the molded product is naturally dried, and then fired. By placing the material on a base plate and firing it, a self-glazing ceramic material that does not adhere to plywood is obtained.
本発明のセラミック材料は例えば電子レンジの導波管カ
バー等全面施釉の必要がない用途に利用できる。The ceramic material of the present invention can be used in applications that do not require full-surface glazing, such as waveguide covers for microwave ovens.
乾燥方法としては、施釉の必要な個所は自然乾燥とし、
他の部分は急速乾燥とする。As for the drying method, areas that require glazing are allowed to dry naturally.
Other parts should be dried quickly.
例えば必要な乾燥防止手段（プラスチックシートの貼着
等）を講じた上で自然乾燥をし、次でこの手段を剥離し
た後、熱風乾燥するとか、或いは乾燥防止手段の除去後
直接焼成炉に入れて焼成温度へ向けて加熱すること（こ
より急速乾燥してもよい。For example, after taking necessary drying prevention measures (such as attaching a plastic sheet), the product is air-dried, then this means is peeled off, and then the product is dried with hot air, or after the drying prevention measures are removed, it is directly placed in a kiln. (Rapid drying may also be used.)
以下実施例について説明する。Examples will be described below.
粘土、タルク、アルミナ等でコープイライト鉱物の組成
（８１０２５１，３ｖｖｔ％、 Ａ１２０３３４．９ｗ
ｔ％、 ＭｇＯ１３，８ｗｔ％）となるよう（こ配合し

３％程度加えた材料を板状に湿式成形する。Copeillite mineral composition (810251.3vvt%, A120334.9w) with clay, talc, alumina, etc.
t%, MgO 13.8 wt%), and the material is wet-formed into a plate shape with about 3% alkaline content such as feldspar added to make it self-glaze.
この成形体は成形直後、水分を１０％前後含んでいるが
、これを次の３方法で乾燥させた。Immediately after molding, this molded product contained approximately 10% water, but was dried using the following three methods.
（１）熱風を用いて表裏両面を急速乾燥する。(1) Rapidly dry both the front and back surfaces using hot air.
（２）表裏両面を自然乾燥する。(2) Air dry both the front and back sides.
（３）板状体の裏面にプラスチックシートを貼りつけ、
表を自然乾燥する。(3) Attach a plastic sheet to the back of the plate,
Air dry the surface.
これらの生成品を裏面を下（こして焼成炉の焼成台板上
へ載せ、溶融直前の温度（１３００℃前後）＊＊で焼成
した。These products were placed with their back sides down on the firing plate of the firing furnace and fired at a temperature just before melting (around 1300°C)**.
上記３の場合はプラスチックシートは剥離して炉に入れ
た。In case 3 above, the plastic sheet was peeled off and placed in a furnace.
焼成品の光沢並びに焼成台板との付着の有無を調べた。The gloss of the fired product and the presence or absence of adhesion to the firing plate were examined.
その結果は次表の通りであった。The results are shown in the table below.
上記表に示したように片面自然乾燥によって焼成台板と
の付着もなく片面のみ光沢のある材料が得られる。As shown in the table above, by air drying on one side, a material with gloss on only one side can be obtained without adhesion to the firing plate.
なお、急速乾燥の場合、水分の急激な移動にアルカリ分
がともなわず表面に光沢が山なかったと考えられる。In addition, in the case of rapid drying, it is thought that the rapid movement of water was not accompanied by alkaline content, and the surface did not have a shiny peak.
以上、本発明は成形後の片面自然乾燥によって片面のみ
光沢のある自己施釉セラミック材料を提供するものであ
る。As described above, the present invention provides a self-glazing ceramic material that is glossy on only one side by air drying on one side after molding.
