Mfundo ndi kugwiritsa ntchito ma demulsifiers

Chifukwa cha kusungunuka kochepa kwa zinthu zina zolimba m'madzi, pamene chimodzi kapena zingapo mwa zinthu zolimbazi zilipo zambiri mumadzi amadzi ndipo zimagwedezeka ndi mphamvu zamadzimadzi kapena zakunja, zimatha kukhalapo mu mkhalidwe wa emulsification mkati mwa madzi, ndikupanga emulsion. Mwachidziwitso, dongosolo lotereli silikhazikika. Komabe, pamaso pa zinthu zosungunulira (monga tinthu ta dothi), emulsification imakhala yoopsa, zomwe zimapangitsa kuti zikhale zovuta kuti magawo awiriwa asiyane. Izi nthawi zambiri zimawonedwa mu zosakaniza za mafuta ndi madzi panthawi yolekanitsa mafuta ndi madzi komanso mu zosakaniza za mafuta ndi madzi pokonza madzi otayira, komwe mapangidwe okhazikika a madzi mu mafuta kapena mafuta mumadzi amapanga pakati pa magawo awiriwa. Maziko a chiphunzitso cha izi ndi "kapangidwe ka magawo awiri."

Muzochitika zotere, mankhwala enaake amayambitsidwa kuti asokoneze kapangidwe kokhazikika ka zigawo ziwiri ndikusokoneza dongosolo la emulsified, motero zimapangitsa kuti magawo awiriwa asiyane. Mankhwalawa, omwe amagwiritsidwa ntchito makamaka kuswa ma emulsion, amatchedwa demulsifiers.

Demulsifier ndi chinthu chomwe chimagwira ntchito pamwamba chomwe chimasokoneza kapangidwe ka madzi osungunuka, motero chimalekanitsa magawo osiyanasiyana mkati mwa emulsion. limatanthauza njira yogwiritsira ntchito mankhwala a demulsifiers kulekanitsa mafuta ndi madzi ndi osakaniza a mafuta ndi madzi osungunuka, zomwe zimapangitsa kuti mafuta osakonzedwa asamathe madzi kuti akwaniritse miyezo yofunikira ya madzi kuti anyamulidwe.

Njira yothandiza komanso yosavuta yolekanitsira magawo achilengedwe ndi amadzi ndi kugwiritsa ntchito ma demulsifiers kuti athetse emulsification ndikusokoneza mapangidwe a emulsification yolimba mokwanira, motero kukwaniritsa kulekanitsa magawo. Komabe, ma demulsifiers osiyanasiyana amasiyana pa kuthekera kwawo kochotsa ma organic magawo, ndipo magwiridwe antchito awo amakhudza mwachindunji magwiridwe antchito a kulekanitsa magawo.

Pakupanga penicillin, gawo lofunika kwambiri limaphatikizapo kuchotsa penicillin kuchokera mu msuzi wa fermentation pogwiritsa ntchito organic solvent (monga butyl acetate). Chifukwa cha kupezeka kwa zinthu zovuta mu msuzi wa fermentation.—monga mapuloteni, shuga, ndi mycelia—Kulumikizana pakati pa magawo a organic ndi amadzi kumakhala kosamveka bwino, zomwe zimapangitsa kuti pakhale gawo la emulsification yocheperako, zomwe zimakhudza kwambiri zokolola za chinthu chomaliza. Kuti athetse vutoli, ma demulsifier ayenera kugwiritsidwa ntchito kuti aswe emulsion, achotse emulsified state, ndikupangitsa kuti magawo achepe mwachangu komanso moyenera.

Lumikizanani nafe!
