Polyterm of solubility of the NH₃-C0₂-H₂0 system

The NH₃-C0₂-H₂0 system is studied by a visual and polythermal method in the range of temperatures from 0 to 85 °C. On a solubility diagram three triple nonvariant nodal points are established. For these points compositions of equilibrium solution and crystallization temperatures corresponding to them are defined.

Polyethylene for production of pipes of the RE-80 standard on the basis of brands of Shurtansky GCC

In article PE80 conforming to requirements on Shurtansky GCC is reported about a possibility of a poluneniye of polyethylene for production of pipes. Properties of similar brands of polyethylene of global manufacturers are analysed that I allow to reveal the directions of modification of ShGHK polyethylene. By the conducted research it is established that at some changes of parameters of production and addition of particular amount of carbon (soot), it is possible to receive polyethylene on properties PE80 meeting the requirements.
