Solvent bonding differs from adhesive bonding, because the solvent does not become a permanent addition to the joined substrate. [4] Solvent bonding differs from other plastic welding processes in that heating energy is generated by the chemical reaction between the solvent and thermoplastic, and cooling occurs during evaporation of the solvent ...
The purpose of installing a cement/mortar lining to the interior wall of the pipe is to reduce the process of tuberculation inside the pipe network. The cement/mortar lining provides an area of high pH near the pipe wall and provides a barrier between the water and the pipe, reducing its susceptibility to corrosion. [1]
