Embodiment 1
[0027] 1) Add 1 kg of wood bran, 10 kg of peanut cake, 3 kg of lignite, and 0.005 kg of yeast, after crushing, add about 1.5 kg of diluted urea solution (the weight concentration of urea solution is 10%) for mixing, and mix and stack at room temperature for fermentation Two weeks (or fermented by fermentation equipment, the fermentation time can be shortened to 24-72 hours), after that, dry it in the sun for three days (or dry it with a drying mechanism), and become a dry product of about 10 kg (organic matter ≥ 70%) ), and carry out secondary pulverization, cross 100 mesh sieves.
[0028] Soak 3 kg of attapulgite in 10% hydrochloric acid by weight for 24 hours, dry at 120°C until constant weight, and crush it for later use.
[0029] 2) Add 8 kg of cornstarch to distilled water, gelatinize at 95°C for 30 minutes, cool down to 40°C, add 3 kg of attapulgite, 10 kg of organic matter, 0.3 kg of initiator potassium persulfate, and 20 kg of propylene under vigorous stirring Amide, ...
Embodiment 2
[0033]1) Put 10 grams of wood bran, 150 grams of bean cake, 35 grams of lignite, and 0.07 grams of yeast. After crushing, add 20 grams of urea solution with a total concentration of 10% for stirring. After mixing, stack them at room temperature for two weeks (or use fermentation equipment to ferment , the fermentation time can be shortened to 24-48 hours), and then dried in the air for three days (or dried with a drying mechanism), and become a dry product with about 140 grams, which is crushed twice and passed through a 100-mesh sieve.
[0034] Soak 78 grams of attapulgite in hydrochloric acid with a total concentration of 10% for 24 hours, bake at 120° C. to constant weight, and grind it for later use.
[0035] 2) Add 150 grams of cornstarch into distilled water, gelatinize at 95°C for 30 minutes, cool down to 40°C, add 78 grams of attapulgite, 140 grams of organic matter, 6 grams of initiator ammonium sulfate, and 120 grams of acrylamide under vigorous stirring , 2 grams of...
