Asphalt film rotary oven structure description:

★ General arrangement: The main body is made of thin steel plate. The upper half is a working room equipped with double doors. The lower half is an electrical control part and a mechanical reduction transmission. The exterior is painted.

★ Observation: The door of the work chamber is a double form. The inner layer is about 30mm thick and the outer layer is about 50mm thick. A square glass observation window is installed in it. There is a light in the room, so that the pool can easily see the indoor state from the outside while the measurement is in progress, and the thermometer is inserted from the upper front.

★ Heating: The heating device is located at the bottom of the studio, and the air is heated by natural air convection. The studio is evenly heated by the up and down air ducts.

★ Insulation and temperature control: The insulation layer and air duct are located between the studio and the casing. In order to prevent the temperature in the working room from affecting the constant temperature and the constant temperature sensitivity, the insulation layer is filled with glass fiber, and the air duct and the studio wall are sprayed high Silver paint. The temperature control is divided into two types of thickness, through the long transfer switch in the 0, 1/3, 2/3, 1, three sections to change the heating wire heating power string to obtain rough temperature rise and temperature control. Adjust the electrical contact thermometer contact installed in the upper part of the working room to obtain the specified operating temperature.

★ Workshop: The workroom is equipped with a turntable where four asphalt containers can be placed. It is driven by a motor. You can also remove the turntable and use it as an ordinary thermostat.

C、將3段轉(zhuǎn)換開(kāi)關(guān)指向1的位置，待整個(gè)工作室溫度上升至所需溫度時(shí)(163℃)應(yīng)檢查工作溫度計(jì)讀數(shù)，通過(guò)調(diào)整電接點(diǎn)溫度計(jì)觸點(diǎn)來(lái)獲得工作室的正確溫度。粗略估計(jì)163℃恒溫功率1300瓦，這時(shí)應(yīng)把3段轉(zhuǎn)換開(kāi)關(guān)指向2/3處(1600w)待整個(gè)工作室在電接點(diǎn)溫度計(jì)控制下，恒溫15min，既可進(jìn)行瀝青薄膜測(cè)定。

★將盛有試樣的盛樣皿放置轉(zhuǎn)盤(pán)上，關(guān)閉烘箱，使轉(zhuǎn)盤(pán)旋轉(zhuǎn)，恒定烘箱溫度在163℃。

★在箱子運(yùn)轉(zhuǎn)中，室內(nèi)照明燈不要隨意啟開(kāi)，以免影響工作室溫度的穩(wěn)定。

★完畢后，必須切斷各個(gè)開(kāi)關(guān)。

Asphalt film rotary oven use method:

★ Power supply equipment: overload safety devices should be installed in the power supply line for this box. And has a good grounding device.

★ Leveling Oven: Rotate the turntable on a horizontal plane, and the inclination angle with the horizontal plane during rotation should not be greater than 3 degrees.

★ Temperature correction:

A. Install a thermometer (the bottom of the mercury ball of the thermometer is about 6.4mm from the surface of the turntable) to calibrate the electrical contact thermometer to the required temperature of 163 ° C.

B. Turn off all switches on the switchboard, plug in the power plug, and turn on the power switch.

C. Point the 3-segment transfer switch to the position 1. When the temperature of the entire working room rises to the required temperature (163 ° C), check the working thermometer reading and obtain the correct temperature of the working room by adjusting the electrical contact thermometer contact. A rough estimate is 1300 watts at a constant temperature of 163 ° C. At this time, the 3-stage transfer switch should be pointed at 2/3 (1600w). The whole studio can be controlled for 15 minutes under the control of an electric contact thermometer to measure asphalt film.

★ Place the sample dish containing the sample on the turntable, close the oven, and rotate the turntable. The constant oven temperature is 163 ° C.

★ During the operation of the box, do not turn on the interior lighting at will, so as not to affect the stability of the studio temperature.

★ When finished, you must turn off each switch.
