Oct 18,2018
The broad prospects of urea-formaldehyde resin in the construction industry can not be questioned, its excellent thickening performance and water retention performance make its application in the construction industry can not be ignored, then, what are the factors affecting the viscosity of urea-formaldehyde resin glue powder, let's understand together.
1. The relationship between viscosity and concentration: the viscosity of urea-formaldehyde resin in aqueous solution rises with the increase of the concentration of the aqueous solution, and a small concentration change in time can also cause a large change in viscosity.
2. The relationship with the polymer: the viscosity of the aqueous solution of urea-formaldehyde resin is proportional to the polymer and molecular weight, and it increases with the improvement of the polymer, and this effect is more obvious in the case of polymerization than in the case of high polymerization.
3. The relationship between viscosity and shear rate: the test shows that urea-formaldehyde resin does not change significantly at low shear rate, and the viscosity decreases with the increase of shear rate.
4. The relationship between viscosity and temperature: urea-formaldehyde resin is greatly affected by temperature, and as the temperature increases, the viscosity decreases.
5. Other factors: viscosity and various additives, solutions, PH value also have an impact.
