Flash point is a safety index for storage, transportation and use of flammable liquids, and it is also a volatile index of flammable liquids.
Flammable liquid with low flash point, high volatility, easy to catch fire and poor safety.
Petroleum products, the flash point below 45℃ for flammable products, such as gasoline, kerosene;
Flashpoint above 45℃ for combustible products, such as diesel oil, lubricating oil.
Lubricating oil with high volatility is easy to evaporate in the process of working, and even causes the increase of lubricating oil viscosity when serious, affecting the use of lubricating oil.
The flash point of flammable liquid is generally required to be 20 ~ 30℃ higher than the operating temperature to ensure the use of safety and reduce the loss of volatilization.
Flash points are items that indicate the evaporation tendency and safety properties of petroleum products. The higher the flash point, the safer it is.
In storage and use, it is forbidden to heat the oil to its flash point. The highest temperature of heating should be generally lower than the flash point of 20~30℃.
Flash point is also important in the use of oil products.
Crude oil flash point detection can be measured by SH105B closed flash point automatic tester, SH105B automatic closed flash point tester is a microcomputer technology, large screen LCD display.
Instrument according to the standard method of heating, automatic rise and fall, automatic ventilation, automatic ignition, automatic display, automatic locking flash point value, automatic printing results.
After the test can be automatically cooled, to achieve the full automation of the work process.
It has the advantages of accurate measurement, good repeatability, stable performance and simple operation.
Widely used in electric power, petroleum, chemical, commodity inspection, scientific research and other departments.
In accordance with ISO - 2719,ASTM D93, GB261-2008 standards
Instruments for the experiment
1.SH105B Automatic Closed Flashpoint Instrument, developed and produced by Shandong Shengtai Instrument Co., Ltd.
2. Closed flash point special cup
Experimental steps:
First, preparation work
1. After the instrument is unpacked, please count the accessories according to the packing list. If there is any damage, please contact our company.
2. The instrument should be carried vertically, and the tilt Angle along the height of the instrument should not exceed 30 degrees. It should be placed in a dark place and placed smoothly, otherwise there will be vibration after the start of the instrument, which will affect the service life of the instrument.
3, the instrument power supply is connected to the capacity of more than 220V/10A socket, pay attention to must have a good grounding wire.
Second, the experimental process
1. After the power is switched on, the test arm of the instrument is automatically lifted to display the experimental interface.
Click "Start", and the test arm falls down to start the test;
Click "Stop" to stop the test and lift the test arm.
The "Test Conditions" section shows the test setting conditions, including the expected flash point, printer switch Settings, and the standard applicable to the test.
The "Test Information" section displays the test progress information.
In the test interface, click "Self-test", "Settings", "Conditions", "Record" and other buttons to enter the corresponding functional interface.
2. Self-check interface
Under this interface, self-check operation can be performed on each component of the instrument.
Click "Test Arm", the test arm component rises;
Click again and the test arm assembly falls.
Click "igniter", point the bright firearm;
Click again to extinguish the igniter.
Click "Stir" to start stirring.
Click again to turn off mixing.
Click "Open the lid" to start the sliding plate of the cup lid and automatically return to its position.
Click "Printer" to start the printer to print self-test. The printer will print the simulated test results (not the real test results) to verify whether the printer works normally.
During the self-test of each component, the corresponding operation information will be displayed below it.
3. Set the interface
Under this interface, you can set the estimated flash point value and atmospheric pressure value. Click "Change" after "Estimated Flash Point" or "Atmospheric Pressure" to enter the interface for setting the estimated flash point or air pressure:
Expected flash point setting
