use
For the determination of various textile mill slurry viscosity slurries of different viscosities can be used to detect four different plates were measured. The viscometer has a simple structure, wide adaptability, easy to use, durable and can be quickly measured characteristics of the slurry viscosity.
YT821 type Funnel viscometer, the choice of the detection plate, directly affect the slurry out of time, so choose properly is very important. Such as the selection plate is too large, the flow time is short; the choice of orifice too small, out for a long time, and the slurry temperature drops too large. Two kinds of the above will affect the measurement accuracy.
According to our experiments and Textile Research Institute, Jiangsu actual usage pulp slurry different viscosity recommended following the detection plate.

Using the methods and precautions
1. Instructions
YT821 type Funnel viscometer Determination pm with a stopwatch. Select the appropriate detection plate according to a slurry concentration. Stopwatch left hand, right hand to take the viscometer. The determination of the first test of the viscometer is immersed in the slurry, (immersion depth is generally the slurry over the tub 2 ~ 3cm can) and later moved up and down several times to stand for 3 minutes, the temperature and the slurry temperature is the same as the barrel, then Gently viscometer quickly raised slurry level height of about 10cm, while pressing a stopwatch (two action requires synchronization), until all the slurry from the bucket out of date (to start flowing slurry bit standard) by stopping the stopwatch, reading record . Continuous, repeated three times to take the average of measured, i.e. the viscosity of the slurry (units / sec).
