Coagulation and flocculation characteristics of talc by different ...
2003年1月1日 As the coagulation of talc suspension in distilled water decreased slowly with increasing pH values, it was strongly coagulated in the presence of cations (i.e., in fresh water) at pH values greater than 10.5, resulting in an increase in the coagulation

Investigation of the co-coagulation of natural rubber latex and ...
2019年12月20日 To achieve a good reinforcing performance from CNCs in rubber, a high level of dispersion is needed. We have studied here the co-coagulation of natural rubber (NR) latex and CNC dispersions, which is possible because of the aqueous colloidal stability of both the CNC dispersion and NR latex.

Mechanisms of pleurodesis
In order to prevent extrapleural talc dissemination, large-particle talc is recommended. Although it could--to some degree--interfere with the mechanisms leading to pleurodesis
