[0100] Raw material name Raw material mass content (%) Water 9.95 Acid Red 33 0.05

[0101] 2. Mixing effect test

[0102] In the test, the base material and the tracer material are added into different mixers (mixer 1-7) according to the ratio of 45g:5g at room temperature. After mixing, the material is moved into a petri dish and spread out, and the uniformity of the tracer is observed to judge the mixing effect.

[0103] (1) Mixer:

[0104] The mixing mode of beaker + stirring paddle, the stirring paddle is a propeller stirring paddle, room temperature 500 rpm, mixing for 10 minutes, the mixing effect has reached the limit, and the mixing effect is shown in Figure 1 .

[0105] From Figure 1 It can be seen that the uniform mixing of the two cannot be realized by using the mixer. This is because the shear force of rotation dissipates very quickly in high viscosity fluid, and cannot tear more fluid units to realize the dispersion of fluid at macro and mesoscopic scale.

[0106] (2) Mixing device:

[0107] Use Figures 2A to 2DThe mixing device was used for mixing, wherein 1 is a flexible mixing chamber made of natural rubber (the orthographic projection size of the flexible mixing chamber is 10cm*15cm), 2 and 3 are the top and bottom sealing sections respectively, and 4 and 4' are the central extrusion module (the central extrusion module is made of metal, and the contact area with the flexible mixing chamber is 10cm*2cm). After 100 extrusions, the mixing effect reached its limit, and the result is as follows. Figure 2E As shown.

[0108] from Figure 2E It can be seen that a mixing device cannot achieve uniform mixing of the two at room temperature.

[0109] (3) Mixing device:

[0110] use Figures 3A to 3D The mixing device consists of a flexible mixing chamber made of natural rubber (10cm x 15cm in orthographic projection), two and three sealing the top and bottom sides, and two and three' forming a central stretching module (made of metal with a contact area of ​​10cm x 2cm with the flexible mixing chamber). After 100 stretches, the mixing effect reaches its limit, as shown in the figure. Figure 3E As shown.

[0111] from Figure 3E It can be seen that a mixing device cannot achieve uniform mixing of the two at room temperature.

[0112] (4) Mixing device:

[0113] use Figures 4A to 4D The mixing device consists of a flexible mixing chamber made of natural rubber (10cm x 15cm in orthographic projection), seals on the upper and lower sides (2 and 3), and a set of rollers (cylindrical, 3cm in diameter and 15cm in length) with gaps between them. The rollers repeatedly roll between the upper seal 2 and the lower seal 3. After 100 repetitions, the mixing effect reaches its limit, as shown in the figure. Figure 4E As shown.

[0114] from Figure 4E It can be seen that a mixing device cannot achieve uniform mixing of the two at room temperature.

[0115] (5) Mixing device:

[0116] use Figures 5A to 5DThe mixing device consists of a flexible mixing chamber made of natural rubber (10cm x 15cm in orthographic projection), two and three sealing the top and bottom sides, and a set of extrusion modules (7 and 7' made of metal with a contact area of ​​10cm x 2cm with the flexible mixing chamber) and another set of extrusion modules (7” and 7”' made of metal with a contact area of ​​10cm x 2cm with the flexible mixing chamber). The two sets of extrusion modules alternately extrude for 100 cycles, after which the mixing effect reaches its limit, as shown in the figure. Figure 5E As shown.

[0117] from Figure 5E It can be seen that a mixing device cannot achieve uniform mixing of the two at room temperature.

[0118] (6) Mixing device:

[0119] use Figures 6A to 6C The mixing device consists of a flexible mixing chamber made of natural rubber (10cm x 15cm in orthographic projection), and two and three sealing sections, respectively. Rollers 8 and 8' form one group (3cm in diameter and 6cm in length), and rollers 8" and 8"' form another group (3cm in diameter and 6cm in length). The rollers repeatedly roll between the upper sealing section 2 and the lower sealing section 3. Gaps exist between 8 and 8', and between 8" and 8"', allowing the flexible mixing chamber 1 to pass through before fluid is added. The rollers 8 and 8" and 8' and 8"' have a gap when they meet, allowing the two groups of rollers to reciprocate between the upper sealing section 2 and the lower sealing section 3. The group of rollers formed by 8 and 8' moves in the opposite direction, but at the same speed and opposite phase, rolling synchronously. After 100 reciprocating cycles, the mixing effect reaches its limit, as shown in the figure. Figure 6D As shown.

[0120] from Figure 6D It can be seen that, using this mixing device, the formulation chassis material and the tracer material are mixed relatively evenly, indicating that using this mixing device can make high viscosity fluid and low viscosity fluid mix evenly at room temperature.

[0121] (7) Mixing device:

[0122] use Figures 7A to 7CThe mixing device is mixed by a mixing device, wherein 1 is a flexible mixing cavity (the size of the orthographic projection of the flexible mixing cavity is 10cm*15cm) made of natural rubber material, 2 and 3 are upper and lower two side seals, and the flexible mixing cavity 1 is fixed on the left support plate 9. 8 and 8" are each a group of rollers (the diameter of the roller is 3cm, and the length of the roller is 6cm), and there is a space between the roller 8 and the support plate 9 and between the roller 8" and the support plate 9, which can allow the flexible mixing cavity 1 before being filled with fluid to pass. The rollers 8 and 8" have a space when intersecting, which can make the two groups of rollers reciprocate between the upper side opening 2 and the lower side opening. The moving direction of the rollers 8 and 8" is opposite, the speed is the same, the phase is opposite, and the rollers roll synchronously. After 100 times of reciprocating motion, the mixing effect has reached the limit, and the result is shown in Figure 7D .

[0123] From Figure 7D It can be seen that the formula base material body and the tracer material body are mixed relatively uniformly by using the mixing device, and it is indicated that the mixing device can make the high-viscosity fluid and the low-viscosity fluid be mixed uniformly at normal temperature.
