It has shown that TPP is an effective deformer in latex paint as well as foam inhibitor without any influence on the paint properties (e. g. viscosity, storage stability and adhesion).
It has obvious actions of leakproof and lost circulation in low pressure absorbent formation because of containing a lot of foam with high shear force and high structural viscosity.
由于含有大量高切力、高结构粘度的泡沫，在低压渗漏地层有显著的防漏堵漏作用。

The paper gives a brief introduction of the installation, the principle and the Computing procedures for measuring the viscosity of foam solution by the capillary method.
