瀝青軟化點測定儀英文版說明書

First, the applicable standard

This instrument was petroleum and petroleum products test method standards T3536-2000 GB/ "petroleum products-determination of Flash and fire (Cleveland Open Cup method) to design and manufacture.

This instrument also applies to JTJ052 2000 highway code T0611 2000 the asphalt for Flash and fire test (Cleveland Open Cup method) and the international prospective ISTMD 2000 test.

2. purpose and scope of application

The tester is applied to Cleveland Open Cup (hereinafter referred to as COC) determination of viscous oil bitumen, coal tar pitch and test 79 ° c above the liquid asphalt material for Flash and fire safety for construction use.

III. instruments and working conditions

        Power supply: 220V ± 10% 50H

        Ambient temperature: -10 ¡æ ~ 50 ¡æ

        Relative humidity: 85%

Fourth, the main features and technical parameter

 Automatic sweep stroke, ignition;

 Electric heating power 0 ~ 400W continuously adjustable;

 Heating wire consists of transparent quartz tube protection, no open flames, explosions, and the temperature rises rapidly;

VI. installation and use

1 , Open box, press the instrument integration and technical documentation to check instrument appearance and related accessories, such as damage or missing, according to the chart shown in the installation.

2 , Check the power supply and grounding is good.

3 , Turn the power switch, the led lights, then you can carry out test operations. 4, specimen Cup with solvent cleaning, drying, installed in the bracket.

5 , Installing thermometers, thermometers, vertical specimen Cup is inserted, the thermometer mercury bulb from the Cup about 6.5mm, location and relative side margin igniter glass edge 16mm.

6 , Sample preparation, sample Cup to marking and other parts of the sample Cup not stained with asphalt. (Note: the sample heating temperature should not exceed the following 55 flash point ℃)

7 , All equipment should be placed in the Interior light darker and no significant air circulation, and three-sided enclosure windscreen.

8 , Ignitor and gas-pressure vessel (e.g. liquefied propane gas or natural gas) with hose connection, turned the ignition, flame ignition testing, debugging into standard ball shape or diameter 4mm ± 0.8mm small spherical flame test.

7. test procedure

1 , Start heating test, so that the heating rate rapidly achieve 14 ¡æ /min ~ 17 ¡æ/min. When the sample temperature is expected to achieve before 56 flash point ℃, adjust the heater to reduce heating rate so that the expected Flash before 28 ° c can make heating rate control in 5.5 ¡æ /min ± 0.5 ¡æ /min.

2 , Sample temperature desired Flash before 28 ℃, every 2 ° c according to the ignition button once so that the flame igniter test centers along the test Cup 150mm RADIUS for arc level scan once, from the experimental side of the Cup to the other side of the elapsed time of about 1s. You should confirm that the pilot flame Igniter for diameter 4mm ± 0.8mm fireball, and is located in the test above 2.5mm Cup. (Note: the test is not a specimen Cup)

3 , When initially appears on the specimen surface in a moment that is off the blue flame, immediay credited from thermometers, temperature on reading as specimens of Flash. Note do not try to flame around the blue and white flame mistaken for the Flash fire.

4 , Continue to maintain sample heating, heating rate 5.5 ¡æ /min ± 0. 5 ¡æ /min, and press the required test CDI ignition.

5 , Immediay when the sample contact flame ignition and combustion can continue for a period of not less than 5s, stop heating, and read the temperature on the recording thermometer as a specimen.

6 At least the same specimen , parallel test twice, two measuring results is less than the margin of a repetitive test allows poor 8 ℃, the average value of the integer as a test result.

7 , Precision or allow poor

Repetitive test allows the poor to: flash point 8 ℃, lighted 8 ℃;

Reproducibility test allows for: flash point 16 ℃, lighted 14 ℃.

8 , After the end of the test, as well as the cleaning and should cut off the power.
