Abstract
【解決手段】耐熱温度1000℃以上の耐火性粉末と水とを含むスラリーを起泡させた気泡含有スラリーを成形乾燥した多孔質の耐火断熱レンガは、気孔率が60%以上であると共に、耐火断熱レンガ内の全気孔容積のうち80%以上の容積が気孔径200μm以下の気孔よりなる。
【選択図】図1
Description
実施例1の配合は表1に示すとおりである。実施例1の主原料である耐火性粉末は、セラミックス粉末である純度99%以上の4種類の高純度アルミナ粉末(Al2O3)よりなる。助剤としては、起泡成分としてポリビニルアルコール(PVA)及びポリオキシエチレンアルキルエーテル硫酸ナトリウム(AES)、気泡安定成分としてメチルセルロース(MC)、保水成分としてグラニュー糖、粘性調整成分として水ガラスを用いている。実施例1として同一配合及び同一製造方法の2つの試験体(実施例1a及び1b)を製造した。
[手順1]MC及びグラニュー糖を75℃の熱湯を用いて充分に撹拌し、溶解させる。
これに水を加えて冷却したものに、PVAとAESを添加し、混合する。
[手順2]予め計量しておいた主原料に、[手順1]で混合したものを加え、
水ガラスを添加した後、
ホイッパー(容量60L、モーター容量2.2kW)を用いて撹拌する。
1速(98rpm)で1分30秒撹拌。
その後、2速(187rpm)で1分30秒撹拌。
その後、4速(333rpm)で2分撹拌し、起泡させる。
[手順3]充分に撹拌し、所定の容量まで泡立たたせた後、
1速で1分30秒撹拌し、気孔径の大きい気泡を取り除き、
スラリーを均一で滑らかな状態にする。
[手順4]これを所定の枠に鋳込む。
[手順5]これを20℃以上に保持した設備で12時間以上養生する。
[手順6]脱型した後、25〜35℃で24時間、45℃で96時間乾燥する。
[手順7]乾燥終了後、1400℃で焼成する。
実施例2は、実施例1と同一の配合で、実施例1よりも気孔率が小さい(かさ比重が大きい)実施例である。実施例2の製造手順は、上記[手順3]の撹拌時間が実施例1よりも短い点を除けば実施例1と同様である。
実施例3は、実施例1と同一の配合で、実施例1及び2よりも気孔率が小さい(かさ比重が大きい)実施例である。実施例3の製造手順は、上記[手順3]の撹拌時間が実施例1及び2よりも短い点を除けば実施例1と同様である。
比較例1は、実施例1と同一の主原料を使用している。比較例1においては、実施例1の助剤を添加することなく、加水のみで耐火断熱レンガを成形しており、比較例1の耐火断熱レンガの気孔率は54.7%である。
比較例2は、実施例1と同一の主原料を使用している。比較例2においては、実施例1の助剤を添加する代わりに、粒径1〜2mmの発泡ポリスチレンビーズ(EPS)を添加することによって耐火断熱レンガの内部に気孔を含有させている。
このようにして製造された実施例1〜3及び比較例1〜2の耐火断熱レンガの品質及び特性は、表2に示すとおりである。表2において、かさ比重は、並型サイズ(230×114×65mm)の試験体から求めた。気孔率は、試験体の全容積に対する気孔容積の比率(%)であり、真比重とかさ比重との関係から、気孔率=(1−かさ比重/真比重)×100という算出式により求めた。気孔径の測定は、水銀圧入法(JIS R1655)によって行った。その他の各試験については、次のとおりJIS規格で定められた耐火断熱レンガの試験方法に準じて行った。圧縮強さ(JIS R2615)、再加熱収縮率(JIS R2613)、熱伝導率(JIS R2616熱線法)、熱間線膨張率(JIS R2617)。なお、表2において、試験を実施していない項目については空白としている。
実施例1a及び1bの気孔測定結果を図1に示す。図1(a)は、横軸を気孔径Φ(μm)、縦軸を気孔容積(mL/g)とした気孔径分布曲線を示している。ここで、水銀圧入法によって測定できる気孔の大きさは、気孔径400〜500μm程度以下であるため、図1(a)に示す気孔径分布曲線には、気孔径400〜500μm程度を超える気孔の測定値が含まれていない。図1(a)に示すように、実施例1a及び1bのピーク気孔径は100μm程度であり、気孔径1μm付近にも小さなピークがある。
図2に実施例1(1a)、2、3、比較例1及び2の熱伝導率の温度変化を示す。かさ比重が大きい比較例1は熱伝導率が大きく、温度の上昇に伴って熱伝導率が徐々に小さくなる傾向がある。比較例2は、比較例1に気孔径1〜2mmの気孔を含有させたものであり、比較例1に比べて熱伝導率が小さくなっている。実施例1(1a)、2、3は、この順に熱伝導率が小さい。各実施例の中で、かさ比重が最も小さく、気孔率が最も大きい実施例1(1a)が最も断熱性に優れている。いずれの実施例及び比較例においても、温度の上昇に伴って熱伝導率が徐々に小さくなるというアルミナ特有の特徴を有している。
実施例4の配合は表3に示すとおりである。実施例4の主原料である耐火性粉末は、セラミックス粉末である純度99%以上の2種類の高純度アルミナ粉末(Al2O3)と、高アルミナ質の天然鉱物であるアンダルサイト(Al2SiO5)及びカイヤナイト(Al2SiO5)と、少量のアルミナセメントとよりなる。これらの耐火性粉末を焼成するとムライト(3Al2O3・2SiO2)が生成される。助剤としては、起泡成分としてポリビニルアルコール(PVA)及びポリオキシエチレンアルキルエーテル硫酸ナトリウム(AES)、気泡安定成分としてメチルセルロース(MC)、粘性調整成分として水ガラス、硬化促進成分として焼石膏を用いている。実施例4の製造手順は、実施例1と同様である。
実施例5は、実施例4と同一の配合で、実施例4よりも気孔径が大きい実施例である。実施例4の製造手順は、実施例1と同様である。
比較例3は、実施例4及び5と同一の主原料を使用している。比較例3においては、実施例4及び5の助剤を添加する代わりに、比較例2と同様に、粒径1〜2mmの発泡ポリスチレンビーズ(EPS)を添加することによって耐火断熱レンガの内部に気孔を含有させている。
このようにして製造された実施例4、5及び比較例3の耐火断熱レンガの品質及び特性は、表4に示すとおりである。表4に示すように、実施例4及び5は、同一の配合及び同一の製造手順で製造されているものの、両試験体のかさ比重、気孔率及び平均気孔径に差が生じている。また、比較例3のかさ比重及び気孔率は、実施例5と同程度となっている。
実施例4及び5の気孔測定結果を図3に示す。図3(a)の気孔径分布曲線に示すように、実施例4のピーク気孔径は20μm程度であり、実施例5のピーク気孔径は100μm程度であることから、同一の配合及び同一の製造手順で製造された耐火断熱レンガであっても、気孔径の分布はある程度ばらつくことがわかる。
図4に実施例4、5及び比較例3の熱伝導率の温度変化を示す。気孔率が小さいムライト質の耐火レンガは、上述した比較例1と同様に、温度の上昇に伴って熱伝導率が徐々に小さくなる傾向がある(図示せず)。これに対して、このムライト質の原料に粒径1〜2mmの発泡ポリスチレンビーズ(EPS)によって気孔を含有させた比較例3のムライト質の耐火断熱レンガでは、温度の上昇に伴って気孔内の輻射伝熱の影響が大きくなるため、熱伝導率が徐々に大きくなる傾向にある。
