Filtering principle
|
|
|
1. By use of “Negative Pressure” to attract
overspray
2.
When the exhausting fan of the booth is
turned on, a strong “Negative Pressure” will
be created to attract the overspray.
Overspray & water mixture will be
co-entrained into the booth by the high
velocity of air flow created by the fan.
An
extreme turbulence as “Tornado Effect” will
be formed to scrub the overspray in the
washing tank. Only exhausted gas will flow
outside – so it can nearly 100% wash away
the overspray.
|

|
|
Advantages |
| |
Any uncaptured overspray (VOC and phosphoric acid) will be present in an
insignificant amount and within the OEL set by the Labour Department of Hong
Kong

RACK ROTATION CABINET |
|
|
1.
coated frames should be
allowed for rotation in the Rack Rotation Cabinet
immediately after coating and before drying in the static oven
2. with the Rotation, formation of drops can be avoided
and the fresh varnish
remains smooth on the surface of the frames
3.
Features:
a.
can hold 10 racks of coated frames
b. rotation time: 3-6 minutes
c. dimension: LxWxH = 1200x550x1700mm

STATIC OVEN FOR FRAME
DRYING
|
|
|
1. Heating
by convention
"horizontal hot air circulation"
& equipped with
"interlock
hot air supply"
to avoid the risk of sudden temperature rise
2.
Oven
temperature: ambient to 220℃,
thermostatic,
self-timing with explosion proof window and
fresh air supply by convention
3.
Perfect insulation: oven outside
temperature is less than 40℃, so
heat loss can be minimized
4.
Control panel composed of: master
switch, thermostatic, automatic drying timer with
alarm, indication lights and

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. |

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.
