The asphalt evaporation loss test box is a professional asphalt testing instrument, which is suitable for determining the evaporation loss of petroleum asphalt materials. The residue after evaporation loss should be tested for penetration. Calculate the percentage of the penetration of the residue to the penetration of the original sample. Be sure to read the instructions carefully beforehand.
Asphalt evaporation loss test chamber features:
It is used to determine the evaporation loss of petroleum asphalt material. The residue after evaporation loss should be tested for penetration. Calculate the percentage of the penetration of the residue to the penetration of the original sample, and determine the ductility of the asphalt residue as needed. Other tests, such as softening points, are used to assess changes in the properties of the asphalt as it is heated.
The instrument is a stainless steel inner tank and a touch switch. It can be set, display set and instantaneous temperature in the temperature range of 50~199 °C. After setting, the oven is thermostated by the automatic control system.

Asphalt evaporation loss test chamber apparatus and materials:
★ Oven: The internal size is not less than 330mm × 330mm, equipped with a temperature automatic regulator, the accuracy of the control temperature is 1 °C. A turntable with a diameter of more than 250 mm is installed in the box, and the center is suspended from the center of the oven by a vertical axis, and the turntable is rotated at a speed of 5.5 r/min ± 1 r/min through a transmission mechanism. The turntable is horizontal and has six concave circular grooves for placing samples. The front side of the oven is equipped with hinged sealing window doors larger than 100mm×100mm. The inner layer of the window door is made of glass. It is not necessary to open the oven door during the test. As long as the window door is opened, the reading of the thermometer in the box can be read through the glass. The oven should have at least one air inlet and one outlet. The oven can also be replaced by a film heating oven used in the T 0609 "asphalt film heating test".
★ Sample dish: made of metal or hard glass, not less than two, flat bottom, cylindrical, inner diameter 55mm ± 1mm, depth 35mm ± 1mm. It can also be replaced with a sample dish with a clean penetration test.
★ Thermometer: 0 ° C ~ 200 ° C, the index is 0.5 ° C.
★ Balance: the sensitivity is not more than 1mg.
★ Others: asphalt melting pot, timer, etc.
