Description
まず、炭素含有廃棄物の大きさを一定とし、界面活性剤及び過酸化水素の量を変化させて試験を行うことにより、界面活性剤及び過酸化水素の量による影響を評価した。以下、この試験を「燃焼性評価試験」という。
炭素含有廃棄物:廃CFRP(炭素繊維含有率:58質量%)
廃CFRPの試料サイズ:平均粒子径1mm
過酸化水素:和光純薬工業製試薬特級(純度30%)
界面活性剤:直鎖アルキルベンゼンスルホン酸ナトリウム、直鎖アルキルベンゼンスルホン酸、及びアルキルエーテル硫酸エステルナトリウム混合物(ライオン株式会社製:ママレモン(商品名))
界面活性剤及び過酸化水素の使用方法:界面活性剤及び過酸化水素が気化した雰囲気下に炭素含有廃棄物を曝露した条件を想定し、廃CFRPを事前に過酸化水素に含侵させることなく、該廃CFRPの周囲に界面活性剤を添加した過酸化水素を滴下して、同時に加熱した。過酸化水素への界面活性剤の添加量は、表1のとおりとした。
炭素含有廃棄物:廃タイヤ
廃タイヤの試料サイズ:3×3×3mm
過酸化水素:試験1と同じ
界面活性剤:試験1と同じ
界面活性剤及び過酸化水素の使用方法:過酸化水素が気化した雰囲気下に界面活性剤が塗布された炭素含有廃棄物を曝露した条件を想定し、界面活性剤を廃タイヤに滴下し、混合することによって、その表面に界面活性剤を塗布した該廃タイヤを、事前に過酸化水素に含侵させることなく、その周囲に過酸化水素を滴下して、同時に加熱した。廃タイヤへの界面活性剤の塗布量は、廃タイヤ100質量部に対し、1質量部とした。
次に、炭素含有廃棄物の平均粒子径を変化させ、界面活性剤及び過酸化水素の量を一定として試験を行うことにより、炭素含有廃棄物の平均粒子径による影響を評価した。以下、この試験を「粒子径評価試験」という。
炭素含有廃棄物:試験例1と同じ廃CFRP(炭素繊維含有率:58質量%)
廃CFRPの試料サイズ:平均粒子径が16mm、9.5mm、6.7mm、4.75mm、2.8mmの5種類
過酸化水素:試験例1と同じ
界面活性剤:試験例1と同じ
界面活性剤及び過酸化水素の使用方法:各廃CFRPに接触させる過酸化水素及び界面活性剤の量は、廃CFRPの量を100質量部としたときに、過酸化水素(純度30%)の量を150質量部、界面活性剤の量を5質量部とした(試験例1の実施例3の試験水準とした。)。
