Description
ライナー(厚さ1.5mm,平均細孔径30μm,気孔率50%)が、芯材(段高1.5mm,段山数8個/cm)に貼付された厚さ3mmの片面Bフルートダンボールシートに、黒鉛粉を混合したフェノール樹脂を含浸させた(樹脂含浸量50質量%,黒鉛含浸量5質量%)。含浸中、ライナーと中芯間の空間に、樹脂が含浸されないよう通風処理等を施した。乾燥後、800℃の仮焼成を行い、ダンボール原紙材料やフェノール樹脂分を炭化すると共にタール等余分な成分を除去した。仮焼成後、2500℃で焼成し、黒鉛化処理を行った。
ライナー(厚さ0.5mm,平均細孔径35μm,気孔率55%)が、芯材(段高1mm,段山数10個/cm)に貼付された厚さ1.5mmの片面Eフルートダンボールシートに、黒鉛粉を混合したフェノール樹脂を含浸させた(樹脂含浸量50質量%,黒鉛含浸量5質量%)。含浸中、ライナーと中芯間の空間に、樹脂が含浸されないよう通風処理等を施した。乾燥後、800℃の仮焼成を行い、ダンボール原紙材料やフェノール樹脂分を炭化すると共にタール等余分な成分を除去した。仮焼成後、2500℃で焼成し、黒鉛化処理を行った。
芯材(段高1mm,段山数10個/cm)の一方の面に、ライナーA(厚さ1.5mm,平均細孔径35μm,気孔率55%)が、他方の面に、ライナーB(厚さ0.5mm,平均細孔径45μm,気孔率70%)が貼付された厚さ3mmの両面Bフルートダンボールシートに、黒鉛粉を混合したフェノール樹脂を含浸させた(樹脂含浸量40質量%,黒鉛含浸量5質量%)。含浸中、ライナーと中芯間の空間に、樹脂が含浸されないよう通風処理等を施した。乾燥後、不活性ガス雰囲気下で、800℃の仮焼成を行い、ダンボール原紙材料やフェノール樹脂分を炭化すると共にタール等余分な成分を除去した。仮焼成後、2500℃で焼成し、黒鉛化処理を行った。
