(1)污染物

 

(1) pollutant

 

污染物具有什么性質，是有機污染還是無機污染，是水溶性的還是油溶性的，是極性污染還是非極性污染；污染物的形態是固體的還是液體的，是粉末狀的還是薄膜狀的；污染物與工件表面粘附的程度是牢固還是不牢固，是屬機械性粘附、物理性粘附還是化學性粘附等。

 

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，是金屬還是非金屬，是潤濕表面還是不潤濕表面，是高能表面還是低能表面，是否容易受腐蝕或受溶脹、溶裂，表面粗糙程度怎么樣，表面有什么保護層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)清洗介質

 

(3) cleaning media

 

潔凈廠房設計施工中根據污染物的性質及與工件表面粘附的情況，確定選用什么清洗介質。是用有機溶劑還是用水基溶劑，是極性溶劑還是非極性溶劑，應對清洗介質的溶解力、表面活性力、化學反應力、工件材料的腐蝕性、相容性以及對使用的經濟性、安全性和對環境的影響等因素，進行綜合分析。

 

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)洗凈工藝

 

(4) cleaning process

 

用什么工藝方法來清洗，使用有機溶劑汽相清洗還是用半水溶劑清洗，或用水基清洗；用浸洗還是用噴洗、擦洗、刷洗，還是用超聲波來清洗或用多種組合來清洗，用高壓噴洗還是用低壓噴洗，在清洗過程中是否需要附加振動、抖動、轉動等；是常溫清洗還是加熱清洗；清洗的工藝流程是分幾次清洗(精洗和粗洗)，幾次漂洗；工件如何干燥，每一步驟需要多少時間，如何達到規定的清潔度，如何防止在清洗過程中受到再污染，以及對清潔度如何監控等。

 

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)清洗設備

 

(5) cleaning equipment

 

用手工清洗還是用機械清洗，工件用什么機構傳送，用批次式清洗機還是用通過式清洗機；用電加熱還是用蒸汽加熱；超聲波選用多大的功率和頻率；清洗時工件如何搖動、抖動、轉動，清洗過程中清洗介質如何循環再生，清洗過程中如何控制，采用什么安全防護措施等。

 

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.
