(1)污染物

 

(1) pollutant

 

污染物具有什么性质，是有机污染还是无机污染，是水溶性的还是油溶性的，是极性污染还是非极性污染；污染物的形态是固体的还是液体的，是粉末状的还是薄膜状的；污染物与工件表面粘附的程度是牢固还是不牢固，是属机械性粘附、物理性粘附还是化学性粘附等。

 

What is the nature of pollution, organic pollution or inorganic pollution, water soluble or oil soluble, is highly polluting or non polar pollution; the form of pollutants is solid or liquid, is a powder like or film; pollutants and the extent of surface adhesion is strong or not strong, is a mechanical, physical or chemical adhesion, etc..

 

(2)工件

 

(2) work piece

 

要清洗的工件是什么材料的，是金属还是非金属，是润湿表面还是不润湿表面，是高能表面还是低能表面，是否容易受腐蚀或受溶胀、溶裂，表面粗糙程度怎么样，表面有什么保护层和有什么特殊要求等。

 

What is the material of the workpiece is to be cleaned, metal or non-metallic, is the wetting surface or non wetting surface, is high-energy surface or low energy surface, whether it is susceptible to corrosion or by swelling, dissolution, surface roughness, what is the surface of the protective layer and what special requirements, etc..

 

(3)清洗介质

 

(3) cleaning media

 

洁净厂房设计施工中根据污染物的性质及与工件表面粘附的情况，确定选用什么清洗介质。是用有机溶剂还是用水基溶剂，是极性溶剂还是非极性溶剂，应对清洗介质的溶解力、表面活性力、化学反应力、工件材料的腐蚀性、相容性以及对使用的经济性、安全性和对环境的影响等因素，进行综合分析。

 

In the design and construction of a clean workshop, according to the nature of the pollutant and the adhesion to the surface of the workpiece, the cleaning medium is determined. Organic solvent or water based solvent, is a polar solvent or non polarity solvent, to deal with the dissolution of the medium, the surface active force, chemical reaction force, the material of the workpiece corrosion, compatibility and the use of economic, safety and environmental impact and other factors, a comprehensive analysis.

 

(4)洗净工艺

 

(4) cleaning process

 

用什么工艺方法来清洗，使用有机溶剂汽相清洗还是用半水溶剂清洗，或用水基清洗；用浸洗还是用喷洗、擦洗、刷洗，还是用超声波来清洗或用多种组合来清洗，用高压喷洗还是用低压喷洗，在清洗过程中是否需要附加振动、抖动、转动等；是常温清洗还是加热清洗；清洗的工艺流程是分几次清洗(精洗和粗洗)，几次漂洗；工件如何干燥，每一步骤需要多少时间，如何达到规定的清洁度，如何防止在清洗过程中受到再污染，以及对清洁度如何监控等。

 

What method to use organic solvent cleaning, vapor phase cleaning or semi aqueous cleaning, or water-based cleaning; with immersion or spray cleaning, cleaning, washing, or ultrasonic cleaning or cleaning with a variety of combinations, with high pressure spray washing or low pressure spray washing, whether you need additional vibration, jitter in the cleaning process, rotating at room temperature or heating; is cleaning cleaning; cleaning process is divided into several cleaning (washing and washing), rinse several times; how to dry, each step requires much time, how to achieve the required cleanliness, how to prevent pollution by another in the cleaning process, and how to monitor the cleanliness of etc..

 

(5)清洗设备

 

(5) cleaning equipment

 

用手工清洗还是用机械清洗，工件用什么机构传送，用批次式清洗机还是用通过式清洗机；用电加热还是用蒸汽加热；超声波选用多大的功率和频率；清洗时工件如何摇动、抖动、转动，清洗过程中清洗介质如何循环再生，清洗过程中如何控制，采用什么安全防护措施等。

 

Hand washing or mechanical cleaning, work with any mechanism, using batch type washing machine or by using the type of cleaning machine; electric heating or steam heating; ultrasonic selection of power and frequency; how to clean the workpiece how to shake, shake, rotate, clean the medium how to recycle, how to control the process, using what security measures.
