Description
Technical field
The present invention relates to a kind of oil absorption material, in particular to a kind of nanofiber oil absorption material.
Background technique
Usually during the processing such as being processed, being transported to petroleum, a considerable amount of Oil spills, discarded are had, no
Limited resource is only wasted, also environment is caused greatly to threaten.Removing oil pollution is very difficult, stone in the world at present
The improvement of oily pollution is divided into chemical method and physical method.
Chemical method: pressing pollution condition, is administered using emulsion dispersion, oil-collecting or solidifying oily method.It is less than the oil of 1mm to thickness
Film is effective using new chemical course cleaning greasy dirt, but chemical debridement methods need to consume a large amount of drug, it is also possible to be caused
Secondary pollution.
Physical method: being most common administering method, including the oil fence, contamination removing ship and attached recyclable device and oil suction material
Material.After generalling use oil fence control greasy dirt range, greasy dirt is adsorbed with asphalt felt.
Asphalt felt be it is a kind of be made by inert chemi-cal polypropylene through melt-blown process, it can effectively adsorb liquid and by it
It keeps here.Adsorption production is all wrapped around in the polypropylene fibre or non-woven fabrics handled through surface activation process agent with sewer,
Outer cloth is extremely tough and tensile durable, has the powerful extremely strong adsorptivity of capillary attraction power bring, to absorb leakage liquid
Oil absorbent material is flowed to, it is reusable after effectively preventing the diffusion of leakage, product to be twisted, squeezed.
However existing asphalt felt oil absorbing effect is not high, asphalt felt intensity is low, easily causes asphalt felt whole after outer layer local damage
