Nekuda kwekunyungudika kwakadzika kwemamwe maonda mumvura, kana imwe kana akati wandei ezvimedu izvi zviripo muhuwandu hukuru mumushonga wemvura uye zvichizununguswa ne hydraulic kana masimba ekunze, zvinogona kuvapo mumamiriro emulsification mukati memvura, zvichiita emulsion. Nechepfungwa, sisitimu yakadai haina kugadzikana. Zvisinei, muhupo hwema surfactants (zvakadai sezvikamu zvevhu), emulsification inova yakaoma, zvichiita kuti zvive zvakaoma kuti zvikamu zviviri zviparadzanise. Izvi zvinonyanya kucherechedzwa mumisanganiswa yemafuta-mvura panguva yekuparadzaniswa kwemafuta-mvura uye mumvura-oiri musanganiswa mukuchenesa mvura yetsvina, uko kugadzikana kwakagadzikana kwemvura-mu-mafuta kana mafuta-mu-mvura maumbirwo anoumba pakati pezvikamu zviviri izvi. The theoretical hwaro hwechiitiko ichi "double-layer structure."
Mumamiriro ezvinhu akadaro, mamwe makemikari emakemikari anounzwa kuti avhiringidze yakagadzikana kaviri-layer chimiro uye kukanganisa iyo emulsified system, nekudaro kuwana kupatsanurwa kwezvikamu zviviri. Aya maajenti, anoshandiswa zvakananga kuputsa emulsion, anonzi demulsifiers.
A demulsifier chinhu chepamusoro-chinoshanda chinokanganisa chimiro chemvura yakashongedzwa, nekudaro ichiparadzanisa zvikamu zvakasiyana mukati memulsion. Crude mafuta demulsification inoreva maitiro ekushandisa demulsifiers 'kemikari chiito kupatsanura oiri nemvura kubva mumusanganiswa wemafuta-mvura musanganiswa, kuwana kupera simba kwemafuta asina kuchena kuti asangane nezvinodiwa zvemukati zvemvura zviyero zvekufambisa.
Nzira inoshanda uye yakatwasuka yekuparadzanisa organic uye aqueous phases ndiko kushandiswa kwe demulsifiers kubvisa emulsification uye kukanganisa kuumbwa kweiyo yakakwana yakasimba emulsification interface, nokudaro kuwana chikamu chekuparadzaniswa. Nekudaro, akasiyana demulsifiers anosiyana mukukwanisa kwavo kudzikisa organic nhanho, uye kuita kwavo kunokanganisa zvakananga kushanda kwekuparadzanisa kwechikamu.
Mukugadzirwa kwepenicillin, danho rakakosha rinosanganisira kubvisa penicillin kubva mumuto wekuvirisa uchishandisa organic solvent (senge butyl acetate). Pamusana pekuvapo kwezvinhu zvakaoma mumuto wekuvirisa-zvakadai semapuroteni, shuga, uye mycelia-iyo interface pakati peiyo organic uye aqueous phases inova isina kujeka, ichigadzira nharaunda yepakati emulsification, iyo inonyanya kukanganisa goho rechigadzirwa chekupedzisira. Kugadzirisa izvi, demulsifiers inofanirwa kushandiswa kutyora emulsion, kubvisa iyo emulsified state, uye kuwana nekukurumidza uye inobudirira chikamu kupatsanurwa.
