Rolling Thin Film Oven About

Thin Film Oven

When the bitumen is heated it loses the volatility and gets hardened. About 50gm of the sample is weighed and heated to a temperature of 163^oC for 5 hours in a specified oven designed for this test. The sample specimen is weighed again after the heating period and loss in weight is expressed as percentage by weight of the original sample. Bitumen used in pavement mixes should not indicate more than 1% loss in weight, but for bitumen having penetration values 150-200 up to 2% loss in weight is allowed.

Precision and Safety in Bitumen Testing

This Rolling Thin Film Oven is engineered to provide consistent and reliable results in bitumen aging tests. Featuring a digital temperature controller and uniform air circulation, the oven ensures controlled conditions and effective specimen processing. Safety is prioritized with over-temperature protection and alarms, while viewing ports and sturdy construction aid laboratory workflows. Its programmable timer and smooth, motor-driven rotation make automated operations straightforward.

Robust Construction for High Performance

The ovens inner chamber is built from stainless steel and insulated with mineral wool, promoting longevity and thermal efficiency. The powdered-coated mild steel exterior adds durability and enhances appearance. The heavy-duty door latch and tempered glass window ensure both security and clear visibility during testing. Designed for ease of use, its table-top mounting and semi-automatic controls support fast setup and minimal maintenance.

FAQs of Rolling Thin Film Oven:

Q: How does the Rolling Thin Film Oven ensure uniform heating and air circulation during bitumen testing?

A: The oven uses a high-quality heating element with mineral wool insulation and a motor-driven mechanism for smooth, uniform bottle rotation. An integrated air flow system maintains an accurate 4000 ml/min rate (200 ml/min), helping achieve even heat distribution and specimen exposure.

Q: What types of bitumen samples can be processed with this oven and how many at one time?

A: This equipment accommodates up to eight standard bitumen sample bottles, each around 140 ml, per testing cycle. It is suitable for bitumen specimens according to ASTM D2872 and IS 9382 compliance requirements.

Q: When should the programmable timer be used and how long can tests be set for?

A: The programmable timer allows users to set test durations from a few minutes up to 999 minutes, making it adaptable for various laboratory protocols and specific bitumen aging test requirements.

Q: Where are safety features implemented in this ovens design?

A: Safety measures include an over-temperature protection system, an alarm for heat irregularities, a tempered glass viewing door, and a heavy-duty latch mechanism to prevent accidental opening during operation.

Q: What is the operational process for running a test using the Rolling Thin Film Oven?

A: Specimens are placed in the chamber, and test parameters like temperature (up to 200C) and timer are set using the digital controller. The oven then heats and rotates bottles uniformly, while air flow remains continuous. Immediate responses can be monitored via the digital LED display.

Q: How does the oven benefit laboratories or manufacturers involved in bitumen analysis?

A: The oven offers precise, consistent test conditions, supports high throughput (eight samples per cycle), and minimizes operator intervention. Its safety, control features, and robust construction enable efficient, reliable analysis for research, quality assurance, or manufacturing processes.
