Embodiment 1
[0086] Fully stir the carbon fiber with a mass fraction of 1% and the polyacrylamide with a mass fraction of 20% in a dry-blending mixer to form a uniform dry-blended polyacrylamide / carbon fiber and set aside. 30% diatomaceous earth, 2% gas phase silica, and 6% sodium carbonate were fully mixed in the reaction kettle, and 35% water was added, and the reaction was stirred at 60°C for 5- 6h, then sequentially add 1% mass fraction of coupling agent KH-560, and 0.5% mass fraction of antifungal agent sodium benzoate, stir in the reaction kettle for 1-2h, and mix to form a uniform slurry. Add dry-blended polyacrylamide / carbon fiber to the above-mentioned uniform slurry, and add 4.5% water, and then vigorously stir and shear to form a uniform hydrogel mud with a certain toughness and moderate hardness; the above-mentioned moderate hardness hydrogel Put the mud into the hopper of the press, adjust the gap between the two rollers of the press to make the forming thickness 5mm, press th...
Embodiment 2
[0091] The ceramic fiber with a mass fraction of 0.5% and the N-methylol polyacrylamide modified condensation polyacrylamide with a mass fraction of 22% are fully stirred in a dry blending mixer to form a uniform dry blended modified polyacrylamide / ceramic fiber, spare. In the reactor, fully mix bentonite with a mass fraction of 35% and chitosan with a mass fraction of 5%, add water with a mass fraction of 33%, stir and react at 50°C for about 8 hours, and then add 0.5% mass fraction of The coupling agent DL602 and the antifungal agent sodium pentachlorophenolate with a mass fraction of 0.5% are stirred in the reaction kettle for 1-2 hours to form a uniform slurry. Add dry-mixed modified polyacrylamide / ceramic fiber to the above-mentioned uniform slurry, and add 3.5% water, and then vigorously stir and shear to form a uniform hydrogel mud with a certain toughness and moderate hardness; Send the hydrogel mud into the hopper of the press, adjust the gap between the two press r...
Embodiment 3
[0096] The mass fraction is 1% glass fiber and mass fraction is 15% hydroxymethyl cellulose, 2% polyacryl alcohol fully stirred in a dry mixing mixer, mixed into a uniform dry mixing hydrogel / glass fiber, spare. Mix 45% diatomaceous earth and 2% chitosan in the reaction kettle, add water with a mass fraction of 30%, stir and react at room temperature for 3 hours, and then add 1% coupling Agent KH-550 and antifungal agent benzoic acid with a mass fraction of 0.5% are stirred in the reaction kettle for 1-2 hours, and mixed into a uniform slurry. Add uniform dry-mixed hydrogel / glass fiber to the above-mentioned uniform slurry, and add 3.5% water, and then vigorously stir and shear to form a uniform hydrogel mud with a certain toughness and moderate hardness; the above-mentioned moderate hardness Send the hydrogel mud into the hopper of the press, adjust the gap between the two press rollers of the press to make the forming thickness 6mm, and press the hydrogel mud tightly at a u...
