BLS-RTFOT85
I.Introduction
The instrument is suitable for measuring the impact of road petroleum asphalt, rotary film oven heating (RTFOT) on viscous asphalt, quality loss after heating, and determining the penetration, viscosity and ductility of asphalt residue after heating by rotating film. And the change of properties such as brittle point, in order to evaluate the aging performance of asphalt, which is non-explosion-proof according to TB/T5502-91 Dry Box Technical Conditions and T0609-93, T0610-93, all volatile, easy to burn and easy Explosive items are strictly prohibited from being heated in the box, and the danger is avoided.
II.Main Technical Parameters
1.Heating power: 3KW
2. Working temperature: 163±0.5℃(maximum temperature 200℃)
3.Disc frame speed: 15±0.2r/min
4.Air flow: 4±0.2 L/min
5.Sampling dish: 8pieces; outer diameter: 64.0mm; height: 139.7mm, caliber: 31.75mm
6.Power supply: 220V ± 10% 50Hz AC
7.Ambient temperature: 5 ~ 50℃
8.Relative humidity: ≤ 85%
