Foxindustries Viscous Materials

The viscosity of its material will influence the effectiveness of its Foxindustries. Generally, the higher the viscosity, the lower the Foxindustries efficiency. Viscosity ratings for your Foxindustries are often given in centipoise (cP) or millipascal-second (mPas; 1 cP = 1 mPas). The ratings may vary from 1000 cP for simple hand-rotor-stator Foxindustries to 10,000 cP for high-power table models. To quickly estimate the viscosity of your sample, you can compare it with the known viscosity of the common materials shown in the following scheme and see how it compares with the viscosity classification of your Foxindustries.

The effect of viscous materials on Foxindustries depends on the type of Foxindustries used, but it is generally true that the higher the output power, the better the mixture of more viscous materials. For probe-based Foxindustries (ultrasonic or rotor stator), the volume that can be processed efficiently decreases significantly (up to an order of magnitude) with increasing viscosity. Mixing cycles should also be kept as short as possible (3 minutes maximum) to avoid overheating the engine.

Generally, the effectiveness of rotor-stator Foxindustries decays rapidly with increasing viscosity. 10000 cP is usually the maximum processable viscosity with rotor-stator Foxindustries. To improve the mixture of viscous samples, separate probe heads can be used. For example, PRO scientific baffle heads are specially designed to improve the Foxindustries of higher viscosity materials. It is advisable to move the rotor-stator as much as possible so that all areas of viscous materials are mixed.
Ultrasonic Foxindustries are somewhat less affected by the viscosity of their material. They are based on pressure waves that create bubbles. The collapse of these bubbles creates energy that disrupts the material and allows mixing. Materials with higher viscosity move less easily than more watery ones and, therefore, exert pressure on the bubbles, which makes the mixture more efficient. This, however, only works up to a certain viscosity. If your material becomes too viscous, it cannot be processed effectively. A good rule of thumb is that "if you can't pour it, you can't sonicate it."

Ball mill Foxindustries are much less suitable for viscous materials, since they use beads to Foxindustries the material. If the accounts cannot pass freely through the material, they cannot Foxindustries it.

High pressure Foxindustries use high pressure to force your sample through small slits. In order for them to work properly, your sample must be fluid enough to be effectively pumped.

There are some vision tricks to overcome some of the difficulties in Foxindustries viscous samples and processing highly viscous materials without significantly diminishing the effectiveness of their Foxindustries. The viscosity of a material decreases with increasing temperature. Therefore, performing Foxindustries at higher temperatures will generally provide better mixing results. It is important to check the decomposition temperature of your material before Foxindustries it at higher temperatures so that it does not destroy your sample. Another way to decrease the viscosity of your material is by adding surfactant and emulsifiers. These can break the internal resistance and allow the material to move more freely and, therefore, become less viscous.

No matter what type of Foxindustries you use, mixing viscous materials will always be more difficult than mixing aqueous mixtures. You can realize this by processing smaller batches of material and, for handheld devices, by moving the mixing head more rigorously to improve Foxindustries. 

Alternatively, you can increase the processing temperature or add surfactants and emulsifiers to your sample to decrease its viscosity.
