Kugwiritsa ntchito ma surfactants otsika thovu poyeretsa mafakitale

Poyeretsa mafakitale, thovu silimangokhudza kuchotsa zinthu zodetsa, komanso limakhala lovuta kutsuka, limakhala ndi zotsalira, ndipo limatha kusefukira kuchokera ku zipangizo zotsukira, zomwe zimayambitsa zinyalala. Komanso, thovu limatha kunyamula zinthu zosungunulira kuchokera ku gawo la madzi otsukira. Chifukwa chake, ndikofunikira kugwiritsa ntchito zinthu zotsukira zopanda thovu kuti mupeze zotsatira zabwino zotsukira.

Kupanga ndi kukhazikika kwa thovu poyeretsa mafakitale kumakhudzidwa ndi zinthu zosiyanasiyana, monga kapangidwe ka ma surfactants, zinthu zina zomwe zili mu yankho loyeretsera, acidity-alkalinity ndi electrolytes, kutentha, kuuma kwa madzi, madontho a mafuta, ndi njira zoyeretsera. Chifukwa chake, ma surfactants otsika thovu amatanthauza ma surfactants omwe sapanga thovu pansi pa mikhalidwe yogwiritsidwa ntchito, kapena omwe thovu lawo ndi losakhazikika ndipo limatha kutha msanga.

Makhalidwe a Ogwira Ntchito Otsika Thovu

Kukana kwa asidi/alkali: Munthawi yabwinobwino, amatha kuonedwa kuti ndi osagwirizana ndi asidi/alkali, makamaka ma ether a alcohol okhala ndi alkyl-capped, omwe amatha kukhala okhazikika kwa nthawi yayitali pansi pa kutentha kwambiri komanso kuchuluka kwa asidi/alkali (kapangidwe kawo sikasintha). Ntchito ya pamwamba: Chifukwa cha kuchepa kwa kapangidwe ka mamolekyulu, kusiyana kwa polarity pakati pa gulu la hydrophilic ndi gulu la lipophilic mu kapangidwe ka amphiphilic ka surfactant kumachepa kwambiri. Kuchepetsa mfundo za mitambo: Chifukwa cha kuchuluka kwa magulu a lipophilic mu kapangidwe kake, mfundo za mitambo za ma surfactants omwe siionic okhala ndi thovu lochepa ndi zochepa. Kutsika kwa mfundo zozizira: Popeza kumapeto kwa hydrophilic kumatsekedwa ndi magulu a lipophilic kapena lipophilic, mphamvu ya mamolekyulu imachepa, zomwe zimapangitsa kuti kuzizira kwa chinthucho kuchepe. Kapangidwe kameneka kamapangitsa kuti zinthuzi zigwiritsidwe ntchito mosavuta. Kuchepa kwa chizolowezi chopanga gel: Chizolowezi cha zinthuzi kupanga ma gels m'madzi chimachepa kwambiri, zomwe zimathandiza kwambiri pokonzekera chinthucho.

Kugwiritsa ntchito ma surfactants otsika thovu poyeretsa mafakitale

Kutsuka makina ochapira mbale: Nthawi zambiri, amatanthauza kutsuka mbale asanalowe mu chotsukira mbale. Kutsuka mkati: Amatanthauza kutsuka nthawi yopanga ndi kukonza chakudya. Mu ntchito yoyeretsa, ntchito yaikulu ya ma surfactants ndi kunyowetsa. Nthawi yomweyo, ma surfactants mu zinthu zotsukira ndi ma surfactants otsika thovu, omwe ali ndi zotsatira zochotsa thovu komanso zoletsa thovu ndipo amatha kuonetsetsa kuti kuyeretsa kukuyenda bwino. Kuyeretsa mabotolo a zakumwa zobwezerezedwanso: Makamaka kumaphatikizapo kutsuka mabotolo a mowa obwezerezedwanso. Kuyeretsa zitsulo: Poyeretsa zitsulo, kuwonjezera pa kunyowetsa, kuchotsa thovu komanso kuletsa thovu, ma surfactants ayeneranso kukhala ndi mphamvu zochotsa thovu. Kuphatikiza apo, pamene kuyeretsa kukupitirira, mabala a mafuta angayambitse kuchuluka kwa thovu m'dongosolo, kotero ma surfactants amafunika kukhala ndi mphamvu zabwino zochotsera thovu. Nthawi yomweyo, sayenera kungotulutsa thovu lochepa komanso amatha kuletsa thovu loyambitsidwa ndi mabala a mafuta.
