Water-borne hinders

Experimental investigationsofthermophysicalpropertiesofsuperheatedwater do not reveal any peculiarities in their behavior. However, it should be borne in mind that by now measurements of properties of metastable water have been made in a very narrow range of state variables. In quasi-static experiments a deep entry into the metastable region of water was hindered by a great number of easily activated boiling sites. D5mamic experiments cannot as yet ensure an acceptable accuracy of measurement of thermophysical properties of metastable liquids. 

The ion separation concern several ions such as Co(II), Ni(II), Zn(ll), Cr(III), and Cd(ll). Depending on the membrane characteristics, it can achieve more than 90 % of removal efficiency with metal concentration from 10 to 112 mg/L. In principle, the separation could be enhanced by using a surfactant such as sodium dodecyl sulfate (SDS) to form micelles or a water-borne polymer such as chitosan to complex ions. However, the membrane fouling problems have hindered this technique from a wider industrial waste-water treatment. 

Circulation studies of water-borne metallic basecoats demonstrate a few reasons why specular reflectance is lost during circulation. The flow induced stress of circulation reduces flake size and produces cycles in liquid surface tension. Surface tension in turn controls amount of picture framing and film thickness. If rust is present in the circulation system, it can react with the paint resins, creating gel lumps which under circulation trap the metal flake hindering flake alignment. Smaller flakes, thicker film thickness and poor aluminium alignment all reduce specular reflectance within the sprayed basecoat paint film [109-115].
