ISO 14644-1 CLEAN ROOM REQUIREMENT

------------------------------------------------------------------------

 

The ISO cleanroom classification standard 14644-1 (implemented in 1999) has replaced the USA FS209E standard and becomes the international clean room standard
 

 

 

ISO 14644-1 defines a clean room as

‘A room in which the number of concentration of airborne particles is controlled and which is constructed and used in a manner to minimize the introduction, generation and retention of particles inside the room and in which other relevant parameters e.g. temperature, humidity and pressure, are controlled as necessary.’

 

‘Cleanrooms can have one or more clean zones, protecting a critical area. The environment for a clean process must not necessarily be a cleanroom but can often be a clean zone in a less clean room. These clean zones can be provided by clean benches, work stations, minienvironments and isolators, the standards of which should also be considered by the designer.’

ROOM AIR

 

 

 

CLEAN ROOM EQUIPMENT 

------------------------------------------------------------------------

 

 AIR SHOWER & CARGO SHOWER
 

 

to blow away dust from workers before entering the spray room to enhance the filtering effect of "Clean Room"

 

 

 

 

 

 FILTERING SYSTEM 
 

 

 

to maintain the clean room in positive pressure so that only clean air will be blown in

By use of “Positive Pressurized Theory”, all outside dirty air can be washed away by 3 layers of filters to ensure only clean air can be supplied into the spray room.

 

 

 

 

 DE-IONIZING CABINET & DE-IONIZING MACHINE
 

 

 

to blow away electro-statics and dust by de-ionized blower

 

 

 CHANGING ROOM
 

 

 

Workers need to wear protective clothing (hoods, face masks, gloves, boots) before entering clean zones  

 

 
     

 

 

 LAMINATED PARTITIONS& EPOXY FLOORING
 

 

 

to reduce electro-statics and dust accumulation

  全自動眼鏡架噴漆機

-------------------------------------------------------------------------

 

 運作原理 

 

 

 

本噴漆機利用 "負空氣壓力" 原理清洗漆氣,能吸引過噴漆氣與水混合, 迫使水缸內之水產生 "龍捲風" 效果來徹底清洗漆油廢氣,讓廢漆留於水缸內,被分離之空氣則排出室外, 所以完全適合任何繁重之眼鏡架噴漆應用.

 

 

 

 優點
  本噴漆機符合香港勞工處規定的廢漆最高可排放量標準 (OEL), 因而成為眼鏡架噴漆界指定使用的噴漆機.

 

       
 

 

     

 

 

 

  塑膠或金屬眼鏡架噴漆機

-------------------------------------------------------------------------

 

 過濾原理 
  1. 鏡框旋轉角度, 噴槍搖擺角度及噴漆次數均可自由調校, 保証漆膜均勻

2. 全機採用不袗製造

3. 配備自動氣噴槍, 生產效率高, 每小時產量達 80 串鏡框

4. 可噴塗細小五金塑膠零件及錶殼

 

 

 

 

 

  金屬眼鏡架噴漆機

-------------------------------------------------------------------------

 

 優點 
 

1. 鏡框旋轉角度可自由調校, 噴槍搖擺角度及噴漆次數均可自由調校, 保証漆膜均勻 

 

2. 可選用自動氣噴漆槍或自動靜電噴漆槍, 生產效率高, 每小時產量達 80 串鏡框

 

3. 可噴塗細小五金塑膠零件及錶殼

 

 

 

 

 

 

   

 

 

  眼鏡架流平機

-------------------------------------------------------------------------

Conclusion

The concentrations of five different parameters in the paint mist were measured at Shenzhen (7-1-98) and Chek Lap Kok (30-7-98) respectively and the results are presented. It is concluded that the VOC (including Isopropyl alcohol, n-butyl alcohol, Ethanol, Methylethyl ketone) and Phosphoric acid arepresent in an insignificant amount and within the OES limit.

 

 

A note on the quoted OES listed in the above table

The full name of OES is Occupational Exposure Standard and it is a concentration of an specific airborne Substance averaged over a reference period at which there is currently no evidence that repeated or day after day exposure by inhalation, will be injurious to the Health of employees. The OES’s should not be exceeded but if this does occur, effective measure should be taken to reduce the exposure as soon as practicable.

The OES quoted here is based on the EH40 which is a part of The Control of Substances Hazardous to Health (COSHH) regulations established by the Health and Safety Executive of UK. 

The objective of this regulation is to prevent disease at workplace due to exposure of hazardous substances.
