Two, require:
(1) polymer formulation concentration is 0.4%.
(2) mixer rotating speed: adjustable.
(3) in whipping process, note the phenomenon of observing each preparation sample, and make a record.
Three, compound method:
(1) load 1600ml water with the beaker of 2000ml, under being placed on mixer, and debugging is to correct position, opens the running water in two mixers stirring cups simultaneously, and rotating speed is adjusted to desired speed.
(2) weigh polymer dry powder 64 grams, totally two parts, respectively in the water respectively to two beakers slowly add polymer dry powder portion.
More than be one group, often adjust a mixing speed later and again do one group according to above method.
Four, experimental conditions describes and analyzes.
Experiment one:
Two kinds of mixers mixing effect contrast (please refer to table 2) under different rotating speeds condition, and two kinds of mixers describe (please refer to table 3) the stirring state of liquid when different rotating speeds.
Under table 2, each speed conditions, two kinds of mixer polymer formulation initial stage mixing effect contrasts
Table 3, two kinds of mixers describe the stirring state of liquid when different rotating speeds
Upper table 2 and table 3 for polymer be just added to the water time, the mixing effect contrast situation of two kinds of mixers, now the viscosity of solution is close to water.
Phenomenon analysis:
(1) as can be seen from the description figure under different speed conditions, each mixer is all the raising along with rotating speed, the rotary speed of liquid in container also improves thereupon, the sinking degree of liquid level is also in continuous aggravation, with this understanding adjustable mixer rotating speed close to or more than 400 revs/min time, internal tank liquid due to rotary speed too fast and screwed out by mouth from container, experiment finds that this adjustable mixer is 50 ~ 100 revs/min than better suited ideal velocity with this understanding.
(2) after polymer solution stirs 10 minutes, the concentration of the polymer in water increases gradually, the viscosity of solution increases simultaneously, the mixing effect of paddle mixer starts to decline, a part absorbs water, polymer beads in course of dissolution has been wrapped on paddle and puddler, starts to occur " pole-climbing " phenomenon.As Figure 12 A, be stirring after ten minutes, the wrapping phenomena schematic diagram that paddle mixer occurs 400 revs/min time.As Figure 12 B, be stirring after ten minutes, the wrapping phenomena schematic diagram that paddle mixer occurs 800 revs/min time.
(3) after polymer solution stirs 30 minutes, along with the dissolving gradually of polymer beads, the viscosity of solution constantly increases, the mixing effect of paddle mixer also declines thereupon, the polymer solution that paddle stirs with the speed of 400 turns per minute is except the solution near paddle is in fine motion thereupon, all the other major parts, close to inactive state, have lost stirring meaning.Specifically please refer to Figure 13 A, is after the rotating speed of 400 revs/min stirs 30 minutes, the wrapping phenomena aggravation of paddle mixer, because solution viscosity increases mixing effect variation schematic diagram.
And can also slowly rotate with the entirety of the polymer solution of 800 turns of high-speed Stirrings per minute, the winding of polymer is also more obvious with " pole-climbing " phenomenon simultaneously. thereuponBut for making polymer solution in process for preparation fully be stirred, the rotating speed of mixer must be improved under existence conditions.Specifically please refer to Figure 13 B, is after the rotating speed of 800 revs/min stirs 30 minutes, the wrapping phenomena aggravation of paddle mixer, because solution viscosity increases mixing effect variation schematic diagram.
(4) polymer solution that adjustable mixer stirs remains polymer solution in container and adjustable mixer run-in synchronism, although polymer beads can make the viscosity thickening gradually of solution in course of dissolution, but the mixing effect of this adjustable mixer is not affected, and there is no " pole-climbing " phenomenon.Under this condition, the rotating speed of adjustable mixer just can reach more satisfactory mixing effect when low speed 50 ~ 100 revs/min.
Experiment two:
The contrast test of two kinds of mixers by changing solution viscosity after the stirring of polymer solution different time under respective fixed rotating speed.
Table 4, the contrast test of two kinds of mixers by changing solution viscosity after the stirring of polymer solution different time under respective fixed rotating speed.
Table 4
In concrete implementation process, above two lot data are made curve, can be more directly perceived.
First batch of experimental data curve please refer to Figure 14.Figure 15 is please refer to condition second batch of experimental data curve.
Analysis of experimental data:
1, a common rule can be found out by above two groups of experiments with condition, the viscosity of this polymer solution preparation initial stage solution is in continuous growth, peak the phase to about one and a half hours viscosity, viscosity growth afterwards obviously slows down, after two hours, viscosity is close to stable, can determine from the Changing Pattern of viscosity, the dissolution velocity of polymer beads in water is more slowly.
2, the regularity of two groups of data is basically identical, in in the early stage 90 minutes, the viscosity of the polymer solution of two mixer stirrings is all be in ascent stage faster, but the viscosity rate of climb of the polymer solution that paddle mixer stirs is slower, although this is because in solution the concentration of polymer in continuous increase, but there is mechanical shearing in the polymer dissolved in advance, result in the loss of a part of viscosity, and adjustable mixer just can make solution be stirred fully when very low rotating speed, significantly alleviate the viscosity loss that polymer solution produces due to mechanical shearing.Now reduce viscosity loss velocity more than 10%.
3, after 90 minutes, the thickening behavior of the polymer solution that adjustable mixer stirs obviously slows down, this is because most of polymer beads is dissolving before completely, is only having and does not have consoluet bulky grain polymer to dissolve in continuation on a small quantity.For the viscosity loss side effect that the mechanical shearing of paddle mixer produces, substantially mask the thickening power of this partial polymer, demonstrate solution viscosity and have a declining tendency.
4, along with the prolongation of mixing time, the side effect that mechanical shearing produces manifests gradually, the gap of the viscosity number of the polymer solution that two kinds of mixers stir also is increasing gradually, but viscosity loss velocity is not unlimited increase, and after about 3 hours, the decrease speed of viscosity is more and more slower.
Five, conclusion.
(1) due to adjustable mixer be non-stop layer swingle chip revolution agitating mode mixer, efficiently solve the pole-climbing problem of polymer in process for preparation.
(2) due to the improvement of agitating mode, make this adjustable mixer when stirring piece 12 low speed revolves round the sun, the liquid of internal tank can obtain overall stirring fully.
(3) due to the leaching of adjustable mixer in the solution be two revolution stirring pieces 12 with certain angle, the liquid in container can be driven in low rotation speed situation to carry out unitary rotation, effectively reduce the viscosity loss that polymer solution causes due to mechanical shearing in process for preparation.
(4) adjustable mixer is applicable to the preparation stirring of viscous fluid, especially has very strong advantage to the polymer solution of high thickness " slide wall ".
(5) two stirring pieces 12 of adjustable mixer have employed the spacing regulating system of screw, simple to operation, and two stirring pieces 12 remain at and the stability in operation process.The large container varied in size can be adapted to.
By one or more embodiment of the present invention, the present invention has following beneficial effect or advantage:
The adjustable mixer of the present invention's design, by the stirring of original High Rotation Speed oar blade type, make the stirring chip stirring at low speed revolved round the sun into, due to the centre rotational axis that this adjustable mixer immersion liquid part is not rotated, so avoid the generation of polymer " pole-climbing " phenomenon in whipping process, and make mixing effect more abundant, effectively can also alleviate the viscosity loss that the mechanical shearing due to the High Rotation Speed of mixing arm brings to polymer solution.
