Introduction to the key points of use of the flat viscometer Flat viscometer is one of the many types of viscometers and has certain applications in many industries
.
Usually viscometer has many advantages such as measurement, simple use, convenient maintenance and good stability
.
Users need to master the use of the viscometer when using it at ordinary times.
The following editor will introduce the use of the viscometer in detail.
I hope it can help you
.
The shape of the flat viscometer can be divided into four types: Ubbelohde, Finn, Ping, and countercurrent
.
The sample viscosity they measure is the kinematic viscosity
.
It has been widely used in petroleum, chemical, light industry, electromechanical, national defense, transportation, coal, food, paper, textile, scientific research, colleges and universities and other units
.
Correct use of capillary viscometers is important to ensure product quality and accurate scientific data
.
1.
Washing and drying: The viscometer must be washed before use.
Generally, it is washed repeatedly with a solvent that can dissolve the residue in the viscometer, then washed with alcohol or gasoline, and then washed with fuming sulfuric acid or potassium dichromate lotion.
Soak for 2-3 hours, and finally rinse with tap water, rinse with distilled water, put it in an oven, and heat it up to about 150 ℃, or invert it at natural temperature for a few days and evaporate to dryness
.
2.
Filling the oil: (except that Wu Shi is poured directly from the seminal tube) Use a rubber ball with a small mouth (ear-washing ball) or a syringe to connect the small glass tube on the seminal tube, hold the viscometer in the left hand, and block it with the index finger Thick tube mouth, turn the viscometer upside down, put the long glass tube with capillary into the sample, pull the syringe, suck the sample to the second coil (so that the liquid level is tangent to the coil), and then stand up.
.
After the countercurrent is installed, the latex tube is clamped with a clip and placed on the tube for aspirating the sample
.
3.
Constant temperature and vertical adjustment: Put the viscometer loaded with the sample on the shelf (clamp) of the constant temperature tank, adjust the left, right, front and rear of the capillary to vertical, keep the constant temperature at the measurement temperature for 10 minutes, start the measurement, and write down The outflow time between the first and second circles is generally carried out three times (except for abnormal numbers) to take the average
.
The above is the relevant introduction about the key points of the use of the viscometer.
I believe that everyone has a relevant understanding of this after reading it.
After mastering the relevant matters, the operation can ensure the accuracy of the test, and I hope it will be helpful to everyone
