洁净室的洁净度要达到要求必须具备的四大条件
发布时间:2019/3/26 8:41:44   点击次数:2290

洁净室要获得良好的洁净效果,不仅要着重采取合理的空调净化措施,而且也要求工艺、建筑及其他专业采取相应的措施:不但要有合理的设计,而且还要精心的符合规范的施工安装,以及正确的使用洁净室和科学的维护管理。为使洁净室获得良好的效果,国内外已有不少文献从不同的角度作过阐述。实际上,不同专业之间很难做到理想地配合,而且设计者很难把握施工安装质量以及使用和管理情况,尤其后者。就洁净室净化措施而言,许多设计者,或者还有施工方,往往对其必要条件未予足够重视,造成洁净效果不理想。本文仅就洁净室净化措施中达到洁净度要求的四个必要条件简要论述。
