It has full-looking and glossy coating resistant to heat, rain and weathering. It can withstand solar thermoradiation and reduce the surface temperature of painting system.
This paper introduces the geological features and the unhomogeneous weathering phenomenon of coral reef limestone of Sudan Port Area,and the bearing capacity of this layer.
The calcite deposits are derived from the recrystallization of the carbonatite as a result of the weathering, eluviation of the fault, and the thermal contact activity and the metamorphism.
There are some independent minerals of Cd, which are secondary minerals formed during weathering and leaching, such as greenockite, otavite and oxides of Cd in the oxidized zone of the deposit.
An oxidized zinc ore from Inner Mongolia was found to be very difficult to treat due to its features of high oxidation rate,heavy weathering and the intimate association of hemimorphite and limonite.
