Description

Bubble Simulation Device {Foam Simulation Tester}

The present invention relates to a device for measuring the foaming force of a cleaning product containing a surfactant as a main component, and more specifically, to generate bubbles by rubbing the brush and the projection by rotating and reciprocating motion to reflect the actual use environment of the cleaning product. It relates to a bubble force simulation apparatus for measuring the bubble force by making.

In general, since the foaming power of the cleaning product is not directly related to the cleaning power, but has an effect of improving the feeling of use, proper foaming power is a very important factor in product quality.

Many methods have been tried for a long time in order to measure the foaming power, but it is difficult to experiment with the actual concentration of the product by the existing method, and it is difficult to test the foaming power of various oil pollution mixtures used as a combination of various surfactants and active ingredients. In the evaluation, the results were different from the actual cases.

The most representative method conventionally used in the bubble force test is the Ross-Miles method (ISO standard 696-1975) standardized in the United States, which uses a low concentration of surfactant solution at a certain height. It is a method to drop and generate bubbles, which is very useful for determining the characteristics of the surfactant, such as the cmc concentration of the surfactant. It is difficult to experiment at high concentration because of the small amount, and it tends not to reflect the effects of oil pollution having various compositions.

In order to overcome these disadvantages, the Shaking method developed by Tipel, the Beh-James method that generates bubbles by inserting and rotating the surfactant solution in the cylinder, and hitting the bubble with a tarpaulin Various attempts have been made, such as a perforated disc method, a method of generating bubbles by blowing a certain amount of air, and a method of generating bubbles by using a mixer. Although the results were partially good compared to the Ross-Miles method, the results were mainly inconsistent with the bubble force generated in actual use.

The present invention was devised to solve the above-mentioned problems, and generates bubbles by rubbing the brush and the projection in consideration of the actual use conditions of the cleaning product, low correlation with the actual use conditions of the conventional test method It is an object of the present invention to provide a bubble simulation apparatus that improves the problem of the.

Other objects and advantages of the invention will be described below and will be appreciated by the practice of the invention. Furthermore, the objects and advantages of the present invention can be realized by means and combinations indicated in the appended claims.

In a configuration comprising a means such as,

By putting an aqueous solution of a cleaning product such as shampoo, soap, dish detergent of the experiment object in the cylinder 10, by simultaneously reciprocating and rotating the brush 8 with respect to the plurality of protrusions 9 to generate bubbles It is characterized by enabling the bubble force to be measured.

Preferably, the reciprocating speed of the brush 8 is 1 ~ 240cpm, the rotational speed is in the range of 1 ~ 240rpm, the diameter is in the range of 0.4-1 to the diameter of the cylinder 10, the reciprocating distance is 30-300 Mm range.

And preferably, the length of the projection 9 is in the range of 0.05-0.3 with respect to the diameter of the cylinder 10, the diameter is 2-20mm, the projection 9 is predetermined on the lower side of the cylinder 10 4-12 pieces are arranged at an angle interval from the height, and 5-20 steps are repeatedly arranged at intervals of 10-50 mm, and the ends thereof are rounded to prevent wear of the brush 8. Done.

Further preferably, the cylinder 10 has a diameter of 15-240 mm and a height of 100-500 mm.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Bubble force simulation apparatus according to the present invention is a device for measuring the bubble force by generating bubbles under conditions similar to the actual use of the cleaning product, at the same time generates a bubble by rubbing the brush reciprocating and rotating movement with the projection for replacing the fingers Let's do it.

The front view of the bubble force simulation apparatus which concerns on this invention in FIG. 1 is shown, and the side view is shown in FIG.

Referring to the drawings, a plurality of projections 9 are laid out on the predetermined lower side inner circumferential surface of one or more transparent cylinders 10 up and down, left and right at predetermined intervals, and the brush 8 reciprocates and rotates from the top. It is located inside the cylinder 10 so as to be friction with the projection 9 by the.

The up and down reciprocation of the brush 8 in the cylinder 10 is obtained by the reciprocating motor 2 and the cam structure 5 which converts the rotational movement by the motor 2 into reciprocating motion, and The rotational movement of the brush 8 is obtained by the motor 1 for rotational movement.

As such, the technique of reciprocating and / or rotating a particular component is very general, in which reference numeral 3 denotes a reciprocating guide, 4 a rotational transmission gear, and 6 a reciprocating slide structure. Instruct each one.

According to the present invention, the case in which the reciprocating motion is obtained by the cam structure 5 will be described as a representative embodiment, but in addition to the conventional reciprocating linear motion method such as crank, link, ball screw, pneumatic, hydraulic method, etc. may be used. Of course.

On the other hand, the speed of the reciprocating motion and the rotational motion of the brush 8 and the number of reciprocating motions are shown in FIG. 2, in which the user manipulates the corresponding reciprocating frequency setting counter 11 and the speed adjusting volumes 12, 13, respectively. It can be adjusted.

According to the invention, the reciprocating distance of the brush 8 depends on the size of the cylinder 10 and the projection 9 used, but preferably about 30-300 mm, and the speed of the reciprocating motion is 0-240 cpm (cycles per minute). ), The speed of rotation is about 0-240rpm.

Brush (8) is made of soft materials such as human hair, animal hair, polyethylene, polypropylene, nylon, urethane, silicone rubber, etc. in consideration of the type of cleaning agent to be tested and the actual conditions of use, and its thickness is about 0.03-1.0 mm. And twist the wool helically or insert a hole of diameter 1-5 mm into a nylon rod of diameter 5-50 mm as shown.

However, since the brush 8 is to generate bubbles by rubbing with the protrusions 9, a porous material such as sponge, cloth or the like may also be used in addition to the brush using a wool.

As shown in Fig. 3, the diameter (a) of the brush (8) is appropriately 15-100 mm, the length (b) is about 30-100 mm, the overall length (c) is suitable about 50-300 mm. .

In addition, the diameter of the brush (8) should be manufactured in a standard suitable for the diameter of the cylinder 10 to be used, the ratio of the diameter of the cylinder 10 and the outer diameter of the brush (8) is in the range of 1: 0.4 to 1: 1. Do.

When the outer diameter of the brush 8 is larger than the diameter of the cylinder 10, when the movement of the brush 8 is not smooth due to the protrusion 9, and the diameter of the brush 8 is less than 0.4 times the diameter of the cylinder 10, Bubble generation hardly occurs.

In this way, it is important to limit the uniformity of the brush 8 standard to be large because the influence on the reproducibility of the experiment is large.

Furthermore, as shown in FIG. 4, the length d of the protrusion 9 disposed on the inner circumferential surface of the cylinder 10 is preferably in the range of 1: 0.05 to 1: 0.3 relative to the inner diameter of the cylinder 10, and the diameter ( e) is suitable for 2-20 mm.

If the projection 9 is less than 0.05 times the inner diameter of the cylinder 10, the friction with the brush 8 is so small that bubbles are not generated smoothly, and if the protrusion 9 exceeds 0.3 times, the brush 8 does not move well. It does not result.

And the excavation of the protrusion 9 excretes 4-12 pieces at a predetermined angle interval from the height of about 10 mm of cylinder 10 lower sides, and 5-20 steps are repeatedly overlapped at 10-50 mm intervals.

Here, the excretion intervals and shapes of the projections 9 may be in the form of a single or multiple spirals, etc., and the shape of the ends thereof is rounded to prevent wear of the brush 8.

On the other hand, the cylinder 10 uses a transparent material capable of measuring the amount of bubbles, suitable for the diameter 15-240mm, height 100-500mm.

Bubble force simulation apparatus according to the present invention having the configuration as described above is put a certain amount of detergent solution of 10-200ml in the cylinder 10, and when the brush (8) up and down reciprocating and rotational movement at the same time bubbles generated between the cleaning agents The bubble difference can be measured.

Referring to the above table, in the case of Example, the foaming power was evaluated in the same order as in Comparative Example 2, which is a consumer evaluation result, but in the case of Comparative Example 1, it was found that the correlation with the consumer evaluation result is very inferior.

Particularly, in the case of soap, when experimenting at a low concentration, such as the Ross-Miles method, the effect of water hardness is large, and as the concentration of the soap solution increases, it becomes a gel-like form, and thus the experiment is impossible at the actual concentration. It was found that it is effective to measure the bubble power of the soap by the test method according to the present invention.
