Abstract
Description
(1)共重合変性、すなわち、共重合により塩化ビニルのセグメントに親水基を有する他
の化学物質を導入すること、
(2)プラズマ表面変性、すなわち、プラズマでポリ塩化ビニル粉末またはポリ塩化ビニ
ル膜を処理し、ポリ塩化ビニル粉末またはポリ塩化ビニル膜の表面に塩素を含む親水基を生じること、
(3)表面グラフト変性(濾膜の化学変性の一種である)、すなわち、γ線または電子線
(ビ−ム)など高エネルギ−放射線で、ポリ塩化ビニルの分子鎖にラジカルを生成し、それからグラフト重合反応により膜表面に必要な親水基を導入すること。上述の三つ種類の方法はポリ塩化ビニル濾膜の親水性を改善するものの、工業化生産が難しく、コストが高い。
本発明のポリ塩化ビニル中空濾膜は、主に下記の成分を含む:
30重量%〜95重量%のポリ塩化ビニルと、
5重量%〜70重量%の塩化ビニル−酢酸ビニル−無水マレイン酸の三元共重合体、
そのうち、上述したポリ塩化ビニルの重合度は700〜2500であり、
上述した三元共重合体において共重合体の総重量に基づいて、酢酸ビニルが10〜19重量%で、無水マレイン酸が18〜40重量%であり、
また、その三元共重合体の絶対粘度が1.2〜1.9mPa・sである。
膜の製造用のスラリ−の総重量に基づいて、
ポリ塩化ビニル 5.6〜14.1%、
塩化ビニル−酢酸ビニル− 0.4〜13.0%、
無水マレイン酸の三元共重合体
熱安定剤 0.1〜0.7%、
溶媒 61.5〜85.1%
制孔剤 1.1〜10.4%
を含有する製膜ためのスラリ−を調製し、
そのうち、ポリ塩化ビニルの重合度が700〜2500で、前記三元共重合体において共重合体の総重量に基づいて、酢酸ビニルが10〜19重量%で、無水マレイン酸が18〜40重量%であり、また、その三元共重合体の絶対粘度が1.2〜1.9mPa・sで
あり、
上述したポリ塩化ビニルと、塩化ビニル−酢酸ビニル−無水マレイン酸の三元共重合体と、安定剤と、溶媒とを上述した比率で混合し、40〜90℃で溶解し、それから制孔剤を添加し、10〜24時間撹拌、溶解続け、10〜15時間静置することによって、製膜ためのスラリ−を形成し、公知の方法によってスプレー製膜し、膜を凝固させ、本発明のポリ塩化ビニルの中空濾膜を製造する。
主な作用はスラリ−のポリ塩化ビニルのサーマルデグラデ−ション(thermal degradation)を調製、加熱する過程において避けるものである。制孔剤は膜の気孔率を高め、膜の透
過能力を増強でき、またある程度に膜の強靭性を向上させる。制孔剤としてポリビニルピ
ロリドン(PVP)、ポリエチレングリコ−ル(PEG)を選んでもよい。ポリエチレングリコ−ル(PEG)が好ましい。膜を製造するためのスラリ−の溶解温度は40〜90℃である。50〜80℃が特に好ましい。
[実施例]
以下、本発明を実施例を挙げて詳細に説明するが、本発明の範囲は下記実施例に限定されることはない。
下に純水の濾過率が800L/m2・hである。
