Commissioning of new waterproofing & XPS Foam Plant
It’s also known as asphalt, Black & highly viscous liquid or semi solid for petroleum. Thanks to its waterproofing qualities. It’s widely used in construction & Bituminous membranes are perfect for waterproofing roofs, basements, below ground structures, bridges & other structures.
The ordinary type bituminous roofing felt or membrane used in this application process, generally, comprises: a base sheet of a sheet-like material such as, for example, paper, felt, fabric, synthetic polymer film or metal foil; a bitumen layer coated on one or both faces of the base sheet, and; mineral granules or powder such as fine gravel, sand or talcum deposited to the surface of the bitumen layer.
Steps of Manufacturing:
- A base sheet such as, for example, paper, felt, woven or non-woven fabric, glass fleece, synthetic polymer film or metal foil, is coated with molten bitumen on one or both faces thereof to form surface layer(s) of bitumen of a suitable thickness.
- When a fibrous sheet such as paper, felt, woven or non-woven fabric or glass fleece, is employed as the base sheet, the fibrous sheet may be impregnated with molten bitumen prior to the coating so that the voids existing in the fibrous sheet are filled with bitumen.
- When a synthetic polymer film or a metal foil is employed, this base sheet may be subjected to surface treatment, prior to the coating, so as to improve its affinity for bitumen.
