Multipolymer Mix: HEC + Sodium Polyacrylate
I tested the combination of HEC and sodium polyacrylate. It was a simple test to see what happens when I mix the two (disastrous or okay).
Temperature 4.6 ℃, humidity 82%, early morning
The solution was made with the following recipe.　(The amount is somewhat arbitrary)
・ 0.7g Sodium Polyacrylate
・ 5.3g HEC (Natrosol 250HHR)
・ 1,000ml hot water (Boiled)
・ 3,334ml tap water
・ 8.0g baking soda
・ 1.3g citric acid
・ 240g Cucute (Japanese detergent)
I added mixed powder of HEC and sodium polyacrylate to hot water 1,000ml little by little while stirring with a magnetic stirrer (and after that, I added baking soda). After stirring with a magnetic stirrer for about an hour, I saw some lumps (It was clearly due to sodium polyacrylate). I added tap wa…
Combination of sodium polyacrylate and Dawn Ultra
I tested the combination of sodium polyacrylate and Dawn Ultra.
Temperature 15 ℃, humidity 88%, after rainfall
(The bubble color profile may be hard to see because the camera exposure adjustment failed.)
The solution was made with the following recipe.
・ 3.0g Sodium Polyacrylate
・ 6,500ml tap water
・ 1.8g citric acid
・ 240g Dawn Ultra
The mixing method is described below: Japanese Soap Bubble (Dec.2020)
As far as I can see, no problem. However, there are some stringing that was not seen in the case of Cucut. For Dawn Ultra, you may need to adjust the amount of polymer or detergent.
When I was trying this solution in a corner of the park, kids rushed in and looked at it with interest.
And after seeing big bubbles and cheering, they said, "I want t…
