This has eventually resulted in increased demand for building materials and wood fibre products.
Generally, this can be achieved by making use of wood instead of either fossil fuels or non-wood materials, such as steel, aluminium and concrete materials.
The availability of timber and other wood-based materials locally in large quantity, particularly in the Southern part of Nigeria facilitates high preference for the choice of these materials for finishes.

The analysis shows that the latex cement can be used for deep soft rock rheology theory and polymer materials similar simulation experiment.
The mechanical properties of the deep soft rock are impacted by the environmental deep rock mass and are difficult to be simulated by actual materials, it is relatively easy that the application of latex cement as the similar material to simulate deep soft rock.
This conclusion is consistent with the experimental data，it proves that a reasonable proportion of the latex cement can be used as a soft rock similar materials.

Additionally, etching submicron features in insulating material such as SiO2 or materials masked with insulators, e.g., photoresistmasked polysilicon, are accompanied by feature charging effects caused by differences in electron and ion angular distributions.

It is more severe if the bending is of small bending radii, thin wall thickness or lower ductility materials.
This makes laser bending is mostly suitable to thin wall or low ductility materials tube.

But if using reclaimed materials to replace the total carbon emissions would reduce 52.90%.
So an innovative technology of PP-R raw materials producing and using more reclaimed materials are the keys to cut down the carbon emissions of PP-R pipe.
Production and processing stage, as different manufacturers using reclaimed materials with different proportions, in order to make the process more clear, this study assumes that in this stage no reclaimed materials has been used.
