GD****4 Oil Content Tester for Petroleum Wax and
Paraffin
Measuring Standard:
1. GB/T***4 “Test Methods
for Oil Content of Petroleum Wax”.
Introduction:
GD****4 Oil content tester for
petroleum wax and paraffin is suitable to determine oil content of
petroleum wax, the congealing point of which is more than *0 ℃ and
the oil content of which is less than *5%.
Note: For some petroleum wax having oil content more than 5%, if
the oil could not be completely dissolved in methyl ethyl ketone
(MEK) and the mixture is separated into two layers, this method is
not applicable.
Characteristics:
1. The special designed refrigeration device,
cooling bath of **5 ℃, contains four cold troughs, so it can make
test for 2 samples at the same time.
2. The wax melting bath and the
evaporator of *5 ℃ are designed as a whole. The lower section is a
wax melting bath having temperature controlling range of room
temperature ~*5℃. The bath temperature can be controlled and
adjustable. The upper section is a air bath evaporation device. Its
controlling temperature is *5 ℃.
3. The temperatures of cooling
bath and bath evaporator are both adjusted and controlled by
digital temperature controller. The temperature can be accurately
adjusted and controlled.
4. The flow rate of air from
evaporator to sample is measured by a glass float-type flow meter.
The flow rate can be accurately controlled as per the test
requirements and the flow time can be preset within *0 minutes
using timer as per the requirements for test time.
5. The instrument adopts desktop
structure. It is novel, and convenient.
