Abstract
Description
圧力で圧着させる。
る。
圧着加熱ガスグラフティング(hot pressed gas grafting)疎水化処理設備を利用して、PVAコーティング耐熱水性紙を製造した。
クアップ(pick up)量を8g/m2に調整した。脂肪酸塩化物としては、パルミトイルクロライド(palmitoyl chloride:C16)とテアロイルクロライド(stearoylchloride、C18)を、5:5で混合した製品を使った。前記PVAコーティング白剥離紙の原紙に、前記脂肪酸塩化物をアニロックス(
anilox)ローラーで塗布量1.3g/m2だけ塗布した。アニロックス(anilox)ローラー、すなわち、グラビア(gravure)ローラーの温度は、60℃に固定したのであり、乾燥ローラーの温度は200℃に調整した。エアナイフフラッシング(air knife flushing)用の高温空気(hot air)の温度は300℃とした。前記処理条件の下、設備の運転速度を50m/minに固定して疎水化処理を行った。
