The length L1 of optionally embodiment, the first pipe 1 is not more than 80mm.In the present embodiment, the length of the first pipe 1
Degree L1 is 80mm.
Optionally embodiment, as shown in figure 3, the second expansion segment 5 was provided with for the first quarter close to one end of the second pipe 6
Line 51 is spent, the second expansion segment 5 is provided with the second graduation mark 52 close to one end of capillary 4.By observing and recording fluid to be measured
Liquid level reaches the time of the second graduation mark 52 from the first graduation mark 51, you can carries out viscosity calculations.
It should be noted that in the absence of conflict, the feature in embodiment in the utility model can be mutual
In conjunction with.
When the micro liquid viscosimeter that the utility model embodiment provides carries out the viscosity measurement of joint fluid, using following step
Suddenly：
1, it by viscosimeter washing lotion and distilled water wash clean, is then dried for standby.
2, regulating thermostatic slot is to (25.0 ± 0.1) DEG C.
3, it takes 1ml joint fluids to be measured to be put into viscosimeter with pipette, then viscosimeter is vertically fixed in thermostat,
Constant temperature 5min~10min.
4, it is connected to air inlet pipe and with sealing-plug by the ferrule of the first pipe with inflating ball, inflates into the first pipe.Wait for liquid
Body rises at the 2/3 of the second pipe, stops inflating, and opens the nozzle of the first pipe.The liquid level that joint fluid is measured using stopwatch is passed through
Time needed between first graduation mark and the second graduation mark.Same operation is repeated, is measured 5 times, it is desirable that each time phase difference is not
More than 0.3s, its average value is taken.
5, the joint fluid in viscosimeter is poured into returnable bottle, uses hot blast drying.1mL distilled water is taken to be put into pipette again
It is same with aforementioned step rephasing in viscosimeter, measure the liquid level of distilled water by needed between the first graduation mark and the second graduation mark when
Between.Repeat same operation, it is desirable that the same.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replace, it should be covered within the scope of the utility model.
