Embodiment 1
[0059] First dissolve 3.08g (1.5%) of KGM in 200ml of 1% glacial acetic acid, make it dissolved and prepare KGM solution, then add 3.20g (1.5%) of CA and 200ml of 1% glacial acetic acid into the KGM solution in turn , the blending temperature was 30° C., the pH was adjusted to 4.06 by adding a 10% NaOH solution, and the blending was stopped after stirring for 40 minutes. The blended solution was poured into a beaker, and the resulting KGM-CA blend was found to be a homogeneous, opaque white gel.
[0060] Using a DV3 viscometer (spindle No. 62, 25°C, 50r / min), the viscosity of the blended solution measured was 696.0mPa·s.
[0061] Fill loose loam to the 3 / 4 place of beaker with the beaker of 500ml, the seedling of a creeper is planted in the beaker, the soil surface is treated flat, then the prepared copolymer solution is directly poured on the surface of the soil. Place the beaker in a laboratory with no wind and no light. Through the side wall of the beaker, it can be seen t...
Embodiment 2
[0063] First 2.04g (1.0%) of KGM was dissolved in 200ml of 1% glacial acetic acid, and then it was dissolved to prepare KGM solution, then 2.12gCA (1.0%) was added to the KGM solution, and the blending temperature was 30°C. The pH was adjusted to 4.07 by adding NaOH solution, and the blending was stopped after fully stirring the reaction for 30 minutes. The blended solution was poured into a beaker, and it was found that the obtained KGM-CA blend was uniform, opaque, with a small amount of white gel, and the solution was slightly yellow and contained a large number of bubbles inside. It can be eliminated after 30 minutes by ultrasonic defoaming.
[0064] Using a DV3 viscometer (spindle No. 62, 25°C, 50r / min), the viscosity of the blended solution measured was 1272.0mPa·s.
[0065] Mix the loose soil with environmentally friendly bentonite cat litter, fill a 500ml beaker with loose loam to 3 / 4 of the beaker, plant a creeper seedling in the beaker, smooth the soil surface, and ...
Embodiment 3
[0067] The KGM of 3.08g (1.5%) is dissolved in the glacial acetic acid of 200ml 1% earlier, is mixed with KGM solution after making it dissolve, then the CA of 3.20g (1.5%) is joined in the KGM solution, blending temperature is 30 °C, adjust the pH to 4.06 by adding NaOH solution with a concentration of 10%, and stop the blending after stirring for 40 minutes. The blended solution was poured into a beaker, and the resulting KGM-CA blend was found to be a homogeneous, opaque white gel.
[0068] Using a DV3 viscometer (spindle No. 62, 25°C, 50r / min), the viscosity of the blended solution measured was 2696.0mPa·s.
[0069]Fill loose loam to the 3 / 4 place of beaker with the beaker of 500ml, the seedling of a creeper is planted in the beaker, the soil surface is treated flat, then the prepared copolymer solution is directly poured on the surface of the soil. Place the beaker in a laboratory with no wind and no light. Through the side wall of the beaker, it can be seen that the cop...
