Study On The Clustering-Based Network Intrusion Detection Methods

Mixed office wastes (MOW) often include most laser and xerographicprinted papers. Such papers are normally of high quality white fibers and arenormally regarded as a potentially extremely valuable feedstock forpapermaking industry. However, the ink utilized in laser and xerographic printedpapers is comprised of a thermoplastic resin which is called toner. Toner inkparticles are particularly troublesome in some deinking operations. To date, theconventional methods adopted for deinking such papers have not beenparticularly successful. The principles of agglomeration and magnetic separationare utilized to study a kind of new deinking process with more efficient, less costand less pollution. First of all, both of agglomerating agent and magnetite areadded to form bigger and magnetic agglomerates. Then those agglomerates inslurry are removed through a high magnetic field. Finally, the removal of ink isobtained. Agglomeration and magnetic deinking process for MOW is the maintopic in the article. By use of light microscope, SEM, magnetometer, Infra-redanalysis and so on, the mechanics of agglomeration and magnetic deinking isstudied. The outcomes are as follows:Signal design testing optimizes the agglomeration and magnetic deinkingprocess for MOW. The optimal deinking process is as follows: agglomeratingagent 2%, magnetite 0.1%, agglomerating pulp density 4%, time 45min,temperature 70℃, separating pulp density 0.7%, applied magnetic 1.74T.The deinking effect of agglomeration and magnetic deinking process is similar to conventional flotation deinking process. But higher fiber yield andlower pollutional load of waste water are obtained by agglomeration andmagnetic deinking process.By use of the SEM and light microscope, 1-octadecanol (C₁₈H₃₈O) is foundthat can make small toner ink particles to be bigger agglomerates with stabilityand compaction. At the same time, the fibers with clean surface are obtained.By use of Infra-red analysis on ink agglomerates, we find characteristicfunctional groups of laser/electrostatic ink don't change, which means that themagnetic deinking is a kind of physical process.Addition of ferromagnetic magnetite can improve susceptibility of toneragglomerates greatly. Particle size and content of magnetite are main factorswhich can affect toner agglomerates' magnetism. Bigger particle size or morecontent of magnetite, higher the toner agglomerates' magnetism is.
