Zogulitsa zathu zazikulu: Amino silicone, chotchinga silika, ma fluoritic iwo, ma fluorine amasuta, Mangapor 8, 1986619 (Whats618)
Mafala Akutoma Nawo
Orfactots ali ndi mawonekedwe amtundu wazomwezi: Mapeto ake amakhala ndi gulu la hydrophilic, pomwe mbali inayo ili ndi gulu la hydrophobic, lomwe limatchedwa mchira wa hydrophobic. Mutu wa hydrophilic amalola okonda zokonda kusungunuka m'madzi mu mawonekedwe awo atomeri.
Gulu la Hydrophilic nthawi zambiri limakhala gulu la Polaryl, lomwe limatha kukhala gulu la Carboxyl (-cooh), gulu la suluno), magulu a amino (-),)
Gulu la hydrophobic limakhala lopanda pake, monga hydrophobic alkyl maunyolo (R- a Alkyl) kapena magulu onunkhira (ar-).
Zogwiritsa ntchito zimagawidwa mu ionic surfactonts (kuphatikiza zikhulupiriro ndi anionic surfactonts), osagwirizana ndi oionic suniculants, ampherotic surfactalts, ndi ena. Mu zothetsera zowonjezera, pamene kuchuluka kwa zowopsazi kukufika pamtengo winawake, mamolekyulu othandiza kwambiri apangidwe osiyanasiyana omwe aperekedwa oitanitsa omwe amatchulidwa kuti amadziwika kuti ndi mikala. Njira ya ma pentillizirization, kapena ma mapangidwe a Miclele, ndi malo ofunika kwambiri othandiza kwambiri, monga zochitika zingapo zofunika kuphatikizidwa ndi mapangidwe a mikala.
Kukhazikika komwe amapanga amapanga ma micrelleles mu njirayi amatchedwa michelle yovuta (cmc). Micleles siili okhazikika, owoneka bwino; M'malo mwake, amawonetsa mosavutikira kwambiri komanso mawonekedwe amphamvu. Panthawi zina, ogwiritsa ntchito amathanso kuwonetsanso machelo.
Zosangalatsa CMC:
- Kapangidwe ka zowonjezera
- Lembani ndi kupezeka kwa zowonjezera
- Kutentha
Kuyanjana pakati paofana ndi mapuloteni
Mapuloteni amakhala ndi polar, polar, ndi magulu oyimbidwa, komanso mamolekyulu ambiri amtundu wambiri amatha kulumikizana ndi mapuloteni m'njira zosiyanasiyana. Kutengera mikhalidwe, ogwiritsa ntchito amatha kupanga maselo opangidwa ndi magulu osokoneza bongo okhala ndi magulu osiyanasiyana, monga ma milielle kapena kusintha ma mateli, omwe amalumikizana mosiyana ndi mapuloteni.
Kuyankhidwa pakati pa mapuloteni ndi maofesi ogwiritsa ntchito (mapuloteni-surticticticnt, KHALO) makamaka ndi magetsi pamagetsi komanso ma hydrophobic. Ionic magaofactonts amalumikizana makamaka kudzera m'magetsi am'magetsi a gulu la polar ndi madera omangiriza ndi madera a hydrophobic a protein, motero amapanga mapulogalamu.
Zosagwirizana ndi ionic zothandizira zimalumikizana ndi mapuloteni a hydrophobic amphamvu, pomwe maunyolo a hydrophobic amalumikizana ndi zigawo za hydrophobic za mapuloteni. Kuchita masewerawa kumatha kupangitsa kapangidwe kake ndi ntchito ya zowonjezera ndi mapuloteni. Chifukwa chake, choyimira ndi kuchuluka kwa okonda, limodzi ndi nkhani yazachilengedwe, dziwani ngati zothandiza kukhazikitsa kapena kuwunika mapuloteni, komanso ngakhale amabala.
Mtengo wa HLB wa Surfacttonts
Kuti muwonetse ntchito yake yapadera, iyenera kuyang'anira hydrophobic ndi hydrophilic zigawo zikuluzikulu. Makina a HLB (hydrophhile-lipophhile) ndi muyeso wa hydrophilic-apophilic moyenera kwambiri ndipo amagwira ntchito ngati chisonyezo cha ogwiritsa ntchito a ydrophilic ndi hydrophobic katundu.
Mtengo wa HLB ndi mtengo wachibale (kuyambira 0 mpaka 40). Mwachitsanzo, paraffin ili ndi mtengo wa hlb wa 0 (wopanda hydrophilic glycol ali ndi mtengo wa HLB ya 20, ndipo mtengo wa HLDS ukhoza kukhala wogwiritsa ntchito zowongolera posankha zochita. Mtengo wapamwamba wa HLB umawonetsa bwino hydrophilicity, pomwe mtengo wotsika wa HLB ukuwonetsa kuti hydrophilicity.
