APP Bitumen Waterproof Membrane

Modified bitumen waterproofing membrane is widely used in industrial and civil buildings, such as roof, basement, toilet, bridge, park, swimming pool, tunnel for waterproof and moisturepr of. Bitumen is a hydrocarbon and is created naturally from crude oil. It is a useful carbon store and does not generate greenhouse gases. The membrane is therefore a sustainable way of storing carbon on the earth's surface.
Working principle
the whole working principle can be divided into 3 steps.
1.to mix the bitumen,rubber powder , talcum powder , enginee oil and some other raw materials via mixing tanks(the mixing tank should be kept warm by conduction oil).the finished mixtures can be called bituminous mixtures .
2.the bituminous mixtures will be delivered into coating pools.then the base material(reinforcement ) will be coated with the bituminous mixtures.at last ,the coated reinforcement will be covered by pe film or sand or other materials.at that time ,the bitumen membrane preliminary forming.
3.the finished products will be cooled by water and air,then be rolled by auto winder.
