  • 实验室装修物料净化应该注意什么?
    来源:最新澳门网址大全 浏览: 发布日期:2020-10-28
    洁净车间设计的物料净化主要是针对原材料、半成品、工具设备等的运输和传递过程中对其进行的清洁处理。物料出入口与人员出入口应分别独立设置。
    The material purification of clean workshop design is mainly for the cleaning treatment of raw materials, semi-finished products, tools and equipment in the process of transportation and transmission. Material access and personnel access should be set separately.
    物料在清洁准备间内经过清洁后,应该如何继续输送下去?主要取决于产品生产工艺流程的要求,它直接影响着清洁准备间的位置选择。物料一般应经过气闸间进人洁净室(区),气闸间往往和洁净室内(区)相毗邻或者就在洁净区内,所以其室内空气压力应与洁净生产区之间保持一个合理的压差。使净化空气从洁净生产区流向准备间。
    How to continue to transport materials after cleaning in the cleaning preparation room mainly depends on the requirements of product production process, which directly affects the location selection of cleaning preparation room. Generally, materials should enter the clean room (area) through the airlock room, which is usually adjacent to or in the clean area. Therefore, the indoor air pressure should be kept at a reasonable pressure difference between the clean production area and the air lock room. Make the purified air flow from clean production area to preparation room.
    如果车间内生产流水性强或为了防止不同等级的洁净室(区)间相互污染或交叉污染或生产工艺要求防止不必要的交叉污染,物料在洁净室之间按照规定工艺流程通过传递窗或者其他装置依次传递。

    If the production flow in the workshop is strong, or in order to prevent the mutual pollution or cross pollution between different levels of clean rooms (areas), or to prevent unnecessary cross pollution according to the production process requirements, the materials shall be transferred successively between the clean rooms through the transfer window or other devices according to the specified process flow.
    为了适应产品、中间产品在工序之间进行物料传递的不同情况,使用的传递窗也有不同的类型。一般多为两道平开门式的箱式传递窗,往往将两道门作成机械联锁开关,即一道门处于关闭状态时,另一道门才能开启;也有的简化为非联锁式,依靠使用人员自行管理;在药品生产工厂采用箱体内部设置紫外灯用于对 传递物进行灭菌;在开关频繁或者开启较长时间的情况下,有的还在箱体内设置有过滤器的空气幕。
    In order to adapt to the different situations of material transfer between products and intermediate products, different types of transfer windows are used. Generally, the two doors are usually used as mechanical interlocking switches, that is, when one door is closed, the other door can be opened; some are simplified as non interlocking type, which depends on the user's self-management; in drug production plants, ultraviolet lamp is set inside the box to sterilize the transfer materials; the other door is opened only when one door is closed; In the case of frequent switching or opening for a long time, some air curtain with high efficiency filter is also set in the box.
    无菌洁净室中经常使用通过式灭菌设备来传递物料,此类设备大多为电热或蒸汽加热,设备一端从有菌区开门,输入物料后经过一段加热灭菌后再从无菌室内开启另一端门取出物料。
    In aseptic clean room, through type sterilization equipment is often used to transfer materials. Most of these equipment are electric heating or steam heating. One end of the equipment opens the door from the bacteria area. After the input of materials, it is heated and sterilized for a period of time, and then the material is taken out from the sterile room by opening the door at the other end.
    此外,流水作业时,有的需要在洁净宰隔墙上开孔,以不断穿墙输出成品,于是孔洞处即成为室内净化的一个薄弱环节。一般处理办法是增加室内正压,或者河时在孔洞上方设置气幕装置;当运输小件物品时,例如无菌室的分装药瓶,也可以在保证室内正压的情况下将传送带分别设在孔洞的两侧,洞口设紫外线灯。
    In addition, during the flow process, some need to open holes on the clean partition wall to continuously output finished products through the wall, so the hole becomes a weak link of indoor purification. The general treatment method is to increase the indoor positive pressure, or set up air curtain device above the hole in the river; when transporting small articles, such as the sub charging bottles in the sterile room, the conveyor belt can be set on both sides of the hole under the condition of ensuring the indoor positive pressure, and the hole is equipped with ultraviolet lamp.
    总之,在物净的区划设计中需要使其与工艺流程、净化空调系统的布置以及物料的传递特点等有机结合起来。同时物净路线应简洁、明确;避免往返、过多曲折和交叉;空间尽量开敞通顺,并应与安全出入口和参观线路等一起考虑。
    In a word, it is necessary to combine it with the process flow, the layout of purification air conditioning system and the characteristics of material transfer. At the same time, the physical and clean route should be concise and clear; avoid going back and forth, too many twists and turns and intersections; the space should be as open and smooth as possible, and should be considered together with the safe access and visiting routes.
