Abstract
Description
次に、平均粒子径1μm〜2mmのアクリルアミド単重合体5.0gにイオン交換水200ミリリットルを吸水させて形成された塊状物を、直径45mmの容器に厚さ6mmとなるように収容し、直径40mmの圧縮板により1Nの荷重を印加する操作を1時間に亘って3600サイクル繰り返し、圧縮時に発生した最大荷重を測定した。結果を実施例として図1に示す。
次に、300ミリリットルビーカーに、平均粒子径1μm〜2mmのアクリルアミド単重合体6.0g、精製水240ミリリットルを添加し、24時間静置して形成された塊状物に市販の家庭園芸用複合肥料(株式会社ハイポネックスジャパン製、製品名:ハイポネックス液6−10−6、水溶性肥効成分として、アンモニア性窒素2.90質量%、リン酸10.0質量%、カリウム5.0質量%を含む)60gを添加した。前記ビーカーを上部を開放した状態で、23±1℃、50±5%RHの室内に静置し、質量減を測定することにより、次式から保水率を求めた。
保水率の経時変化を実施例として図2に示す。
次に、平均粒子径1μm〜2mmのアクリルアミド単重合体5.0gに精製水500ミリリットルを吸水させて形成された塊状物に、肥料(水溶性肥効成分として、アンモニア性窒素3.12質量%、リン酸11.7質量%、カリウムを3.84質量%、マグネシウム0.04質量%を含む)を0.125g添加して、緩効性肥料組成物を調製した。
各水溶性肥効成分の質量は、アンモニア性窒素及びリン酸についてはIC(イオンクロマトグラフ)法により求め、カリウム及びマグネシウムについてはICP−AES(誘導結合プラズマ発光分析計)により求めた。結果を表1に示す。
各水溶性肥効成分の質量は、24時間静置後に分離された水分の場合と全く同一にして求めた。結果を表1に示す。
Claims (1)
