ISO 14644-1無塵噴漆房規定:
------------------------------------------------------------------------
|
ISO 14644-1 (於
1999 執行) 這國際標準已取代美國的
FS209E 對無塵噴漆房的規定:
|
|
|
1.無塵房內的溫度,
濕度及壓力會影響塵粒含量
2.無塵房內必須有無塵工作台,
風淋室及除塵柜以確保無塵房可達致不同級別的無塵房要求

無塵房設備
------------------------------------------------------------------------
|
風淋室及貨淋室 |
| |
讓噴漆工在進入噴漆房前清洗身上的灰塵以便提升
"正壓無塵噴漆房"
的過濾效果
|
|

|
 |
 |
|
空氣濾塵機
|
|
|
為了提高客戶的產品質素令工件表面不含塵粒,
噴漆房內必須配合濾塵式強制給氣系統, 增加噴漆房氣壓, 以便形成
"正壓無塵噴漆房",令噴漆房車間內潔淨空氣的壓力大過噴漆房外,
故就算噴漆工人經常進出噴漆房, 房外空氣也不易混入, 確保工件表面無明顯塵粒
|
 |
 |
 |
|

|
 |
 |
|
除塵柜及靜電除塵器
|
|
|
利用離子風去除工件表面靜電和塵粒
|
 |
 |
 |
 |
 |
 |
|
更衣室及工作服
|
|
|
在靜電塗裝區內,
噴漆工不可穿著纖維容易脫落的衣服

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 |

|
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

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.
