The flash point of diesel oil at atmospheric pressure is above 55℃.
Flash point is a safe index for storage, transportation and use of combustible liquids, and also a volatile index for combustible liquids.
Low flash point flammable liquid, high volatility, easy to fire, poor safety.
Diesel is a light petroleum product, a complex mixture of hydrocarbons (carbon atoms approximately 10 ~ 22).
Fuel for diesel engines.
It is mainly composed of diesel fractions produced in the processes of crude oil distillation, catalytic cracking, thermal cracking, hydrocracking and petroleum coking.
It can also be produced from shale oil processing and coal liquefaction.
Flash point is a safe index for storage, transportation and use of combustible liquids, and also a volatile index for combustible liquids.
Low flash point flammable liquid, high volatility, easy to fire, poor safety.
Diesel flash point detection can be measured by SH105B automatic closed-mouth flash point tester, which adopts microcomputer technology and large-screen LCD.
The instrument is heated according to the standard method, automatic lifting, automatic ventilation, automatic ignition, automatic display, automatic locking flash point value, automatic printing results.
After the completion of the test can be automatically cooled, the work process to achieve full automation.
It has the advantages of accurate measurement, good repeatability, stable performance and simple operation.
Widely used in electric power, petroleum, chemical industry, commodity inspection, scientific research and other departments.
Comply with ISO - 2719,ASTM D93, GB261-2008 standard
Apparatus needed for experiment
1.SH105B automatic closed-mouth flash point instrument, developed and produced by Shandong Shengtai Instrument Co., LTD.
2. Special cup for closed-mouth flash point
Experimental steps:
Preparation work
1. After unpacking the instrument, please count the accessories according to the packing list. If there is any damage, please contact our company.
2. The instrument should be handled vertically. The tilt Angle should not exceed 30 degrees along the height of the instrument.
3. Connect the power supply of the instrument to the socket with a capacity of 220V/10A or above, and pay attention to having a good grounding wire.
Ii. Experiment process
1. After the power is switched on, the measuring arm of the instrument will lift automatically to display the experimental interface.
Click "Start" and the test arm drops to start the test.
Click "Abort" to stop the test and the test arm rises.
The "Test Conditions" section shows the test setting conditions, including expected flash points, printer switch Settings, test criteria, etc.
The "Test Information" section shows the progress of the test.
In the test interface, click "self-check", "Set", "condition", "record" and other buttons to enter the corresponding functional interface.
2. Self-check interface
This interface can perform self-check operation on all parts of the instrument.
Click "Test arm", and the test arm assembly will rise;
Click again, and the test arm component drops.
Click "igniter" to light the highlight igniter;
Click again to extinguish the ignition.
Click "Stir" to start stirring;
Click again and close the stirring.
Click "Open the lid", start the lid skateboard to run, and automatically return to position.
Click "Printer" to start printer printing self-test. The printer will print simulated test results (not real measurement results) to verify whether the printer is working properly.
During the self-inspection of each component, the corresponding operation information will be displayed below it.
3. Interface setting
From this interface, expected flash point value and atmospheric pressure value can be set: Click "Expected Flash point" or "Change" after "atmospheric pressure" to enter the expected flash point or atmospheric pressure setting interface:
Expected flash point setting
