    • The present invention provides a method for continuously washing poly(vinyl butyral) in which a poly(vinyl butyral) slurry is passed through multiple continuous stirred tank reactors, each of which is adjusted to specific processing parameters that allow for continuous input, washing, and removal of poly(vinyl butyral). The resulting poly(vinyl butyral) can then be dried to form a powder resin that can be used in place of conventional poly(vinyl butyral) resin. In an alternative embodiment, a counter current screw washing unit is provided that passes wash water over the poly(vinyl butyral) in a direction opposite to the flow of the poly(vinyl butyral), thereby allowing the continuous washing of the poly(vinyl butyral) resin.
    • 本发明提供了一种连续洗涤聚(乙烯醇缩丁醛)的方法,其中聚(乙烯醇缩丁醛)浆料通过多个连续搅拌釜反应器,每个反应器被调整为允许连续输入,洗涤和 去除聚(乙烯醇缩丁醛)。 然后可将所得聚(乙烯醇缩丁醛)干燥以形成可用于代替常规聚(乙烯醇缩丁醛)树脂的粉末树脂。 在替代实施例中,提供了一种逆流螺杆洗涤单元,其在与聚(乙烯醇缩丁醛)流动相反的方向上将洗涤水通过聚(乙烯醇缩丁醛),从而允许连续洗涤聚(乙烯基缩丁醛 )树脂。
