Introduction:
The instrument is designed and manufactured in accordance with the requirements of the People's Republic of China GB / T3554 "Determination of oil content of petroleum wax" and is suitable for the determination of the wax freezing of 30 ° C or higher and the oil content of not more than 15% Oil content.
Note: Some oil containing more than 5% oil, if the oil can not be completely dissolved in the butanone and layered, it is not appropriate to use this method. Features:
1, -35 ℃ cold bath for the independent design of the refrigeration device, a total of four cold, two groups can be tested in groups.
2, the wax water bath, 35 ℃ evaporator designed as a whole, the lower part of the room temperature ~ 95 ℃ wax water bath, water bath temperature control, adjustable; the upper part of the air bath evaporator, the control temperature 35 ° C.
3, cold bath and water bath evaporator temperature adjustment and control are used digital temperature controller, temperature control and control accuracy.
4, the amount of blowing into the sample into the sample by the glass rotor flowmeter detection, according to the specific requirements of the test to accurately control the amount of blowing, blowing time according to the test time required by the timer in 60min arbitrarily set.
5, the overall design of the instrument for the desktop structure, innovative design, reasonable structure, easy to use. Technical Parameters:
1, work power: AC 220V ± 10% 50Hz;
2, the wax water bath temperature: room temperature ~ 90 ℃ ± 5 ℃
3 ﹑ cold bath temperature: -35 ℃ ± 1 ℃;
4, evaporation temperature: 35 ℃ ± 1 ℃;
5, air blowing flow: 2 ~ 3L / min;
6, the timer timer range: 0 ~ 60min.
