Embodiment 1
[0013] 40% thiourea, 20% sodium sulfite, 10% EDTA, and the remaining water. Heat the water to 50-60°C, add other components, and stir for 30 minutes to obtain a polymer viscosity stabilizer.
Embodiment 2
[0015] 50% thiourea, 30% sodium sulfite, 5% EDTA, and the rest of water. Heat the water to 50-60°C, add other components, and stir for 30 minutes to obtain a polymer viscosity stabilizer.
Embodiment 3
[0017] 45% thiourea, 25% potassium sulfite, 10% EDTA, and the remaining water. Heat the water to 50-60°C, add other components, and stir for 30 minutes to obtain a polymer viscosity stabilizer.
