Thu, 19 Apr 2007 05:00:53 +0000 tommy http://www.guimod.com/blog/index.php/573.html =0.5μm之微尘粒子数目字以10的幂次方表示，取指数为之，若微尘粒子数介于前后二者完全幂次方之间，则以1.5、2.5、3.5….表示。 美国联邦标准FS 209D都以英制每立方英呎为单位，日本则是采用公制，即以每立方公尺为单位，以0.1μm微粒子为计数标准。日本标准之表示法以Class 1，Class 2，Class 3……Class8表示，最好的等级为Class 1，最差则为Class 8，以每立方公尺中微尘粒子总数中化为10的幂次方，取其指数而得。 (三)洁净室控管之项目 1. 能除去空气中飘游之微尘粒子。 2. 能防止微尘粒子之产生。 3. 温度和湿度之控制。 4. 压力之调节。 5. 有害气体之排除。 6. 结构物与隔间之气密性。 7. 静电之防制。 8. 电磁干扰预防。 9. 安全因素之考虑。 10. 节能之考量。 (四)洁净室之分类 1.乱流式(Turbulent Flow)： 空气由空调箱经风管与洁净室内之空气过滤器(HEPA)进入洁净室，并由洁净室两侧隔间墙板或高架地板回风。气流非直线型运动而呈不规则之乱流或涡流状态。此型式适用于洁净室等级1,000-100,000级。 优点：构造简单、系统建造成本，洁净室之扩充比较容易，在某些特殊用途场所，可并用无尘工作台，提高洁净室等级。 缺点：乱流造成的微尘粒子于室内空间飘浮不易排出，易污染制程产品。另外若系统停止运转再激活，欲达需求之洁净度，往往须耗时相当长一段时间。 2.层流式(Laminar)： 层流式空气气流运动成一均匀之直线形，空气由覆盖率100%之过滤器进入室内，并由高架地板或两侧隔墙板回风，此型式适用于洁净室等级需定较高之环境使用，一般其洁净室等级为Class 1~100。其型式可分为二种： (1)水平层流式：水平式空气自过滤器单方向吹出，由对边墙壁之回风系统回风，尘埃随风向排出室外，一般在下流侧污染较严重。 优点：构造简单，运转后短时间内即可变成稳定。 缺点：建造费用比乱流式高，室内空间不易扩充。 (2)垂直层流式：房间天花板完全以ULPA过滤器覆盖，空气由上往下吹，可得较高之洁净度，在制程中或工作人员所 产生的尘埃可快速排出室外而不会影响其它工作区域。 优点：管理容易，运转开始短时间内即可达稳定状态，不易为作业状态或作业人员所影响。 缺点：构造费用较高，弹性运用空间困难，天花板之吊架相当占空间，维修更换过滤器较麻烦。 3.复合式(Mixed Type)： 复合式为将乱流式及层流式予以复合或并用，可提供局部超洁净之空气。 [...]]]> http://www.guimod.com/blog/index.php/573.html/feed 78
