沥青薄膜旋转烘箱结构说明

★总体安排:主体由薄钢板构成,上半部是装有双重门的工作室,下半部是电器控制部分和机械减速传动装置,外表喷漆。

★观察:工件室门是双重形式,内层厚约30mm,外层厚约50mm,装有方形玻璃观察窗。在室内有照明灯,可以在测定进行时能方便池从外面看到室内状态,温度计从上部前面插入。

★加热:加热装置在工作室底部,采用空气自然对流法加热空气。通过上下和背后的风道均匀加热工作室。

★保温和控温:工作室和箱壳之间是保温层和风道,为使工作室内温度不致外导而影响恒温和恒温灵敏度,保温层内充填玻璃纤维,风道和工作室壁上喷高银粉漆。控温分粗细两种,通过长转换开关在0、1/3、2/3、1、三段中的转换,改变电热丝加热功串获得粗略的升温和控温。调整安装在工作室上部的电接点温度计触点,获得指定的工作温度。

★工作室:工作室装有可以放置四只沥青盛样皿的转盘它由电机带动。也可以取去转盘,作为普通很恒温箱使用。

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.

 

沥青薄膜旋转烘箱使用方法

★电源设备:应在供电线路中装有超负荷的保险装置,供此箱专用。并具有良好的接地装置。

★校平烘箱:使转盘在水平面上旋转,旋转时与水平面的倾角不得大于3度。

★温度校正:

A、装上温度计(温度计水银球底部距离转盘项面约6.4mm)校对电接点温度计至所需温度163℃。

B、关闭配电盘上所有开关,将电源插头插上,打开电源开关。

C、将3段转换开关指向1的位置,待整个工作室温度上升至所需温度时(163℃)应检查工作温度计读数,通过调整电接点温度计触点来获得工作室的正确温度。粗略估计163℃恒温功率1300瓦,这时应把3段转换开关指向2/3处(1600w)待整个工作室在电接点温度计控制下,恒温15min,既可进行沥青薄膜测定。

★将盛有试样的盛样皿放置转盘上,关闭烘箱,使转盘旋转,恒定烘箱温度在163℃。

★在箱子运转中,室内照明灯不要随意启开,以免影响工作室温度的稳定。

★完毕后,必须切断各个开关。

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.
