Embodiment 1
[0035] The following content of the present embodiment has described the manufacture process of waterproof foam concrete:
[0036] First take 32 kg of powdered animal fur, hoof horn and other keratin protein powder, 1.8 kg of NaHSO 3 , 300 kg of water was added to the reactor, mixed and stirred, and pretreated at a constant temperature of 40°C for 2 hours. Then add 4.5 kg of Ca(OH) 2 , maintain a constant temperature of 80 ° C, hydrolysis reaction for 4 hours. After entering the filter and filtering, enter the reaction kettle for the second time, keep a constant temperature of 80°C, add an appropriate amount of sulfamic acid to neutralize to a pH of about 7. After reacting for 1 hour, enter the filter again, after filtering, enter the concentration tank for high-temperature dehydration, enter the reaction kettle for three times at a constant temperature of 60°C, add 1.0 kg of sodium dodecylbenzenesulfonate aqueous solution and 0.5 kg of sodium dodecylsulfonate aqueous soluti...
