In ukucoca kwimizi-mveliso, igwebu aligcini nje ngokuphazamisa ukucoca kodwa likwabangela ukuba ukuhlanjwa kube nzima, lishiya amasalela, kwaye lisenokugcwala kwizixhobo zokucoca, nto leyo ebangela inkunkuma. Ukongeza, igwebu linokuhlutha izinto ezibangela ukuba i-surfactants ingangeni kwisigaba solwelo lokucoca. Ke ngoko, iimveliso zokucoca ezine-foam ephantsi ziyafuneka ukuze kufezekiswe ukusebenza kakuhle kokucoca.
Ukuveliswa kunye nokuzinza kwe-foam ekucoceni kwemizi-mveliso kuchaphazeleka zizinto ezahlukeneyo, ezifana nolwakhiwo lwe-surfactants, ezinye izinto kwizisombululo zokucoca, amaxabiso e-pH kunye nee-electrolytes, ubushushu, ubulukhuni bamanzi, ungcoliseko lweoyile, kunye neendlela zokucoca. Ke ngoko, ii-surfactants ezine-foam ephantsi zibhekisa kwi-surfactants ezingavelisi foam okanye i-foam engagungqiyo enyamalala ngokukhawuleza phantsi kweemeko zenkonzo.
Iimpawu zokusebenza zeIi-Surfactants eziphantsi kwe-Foam
Ukumelana ne-Acid kunye ne-Alkali: Phantsi kweemeko eziqhelekileyo, zinokuthathwa njengezimelana ne-asidi kunye ne-alkali. Ngokukodwa, ii-ethers zotywala ezine-alkali ezigqunywe yi-alkali zinokuhlala zizinzile ixesha elide phantsi kweemeko zobushushu obuphezulu, i-asidi enamandla kunye ne-alkali enamandla ngaphandle kotshintsho kwizakhiwo zazo zangaphakathi.
Umsebenzi woMphezulu: Uthintelwe yisakhiwo se-molecular, umahluko we-polarity phakathi kwamaqela e-hydrophilic kunye namaqela e-lipophilic kwisakhiwo se-amphiphilic se-surfactants uncitshiswe kakhulu.
I-Cloud Point Encitshisiweyo: Ngenxa yamaqela e-lipophilic akhulayo kwisakhiwo, ii-surfactants ezingezizo ii-ionic ezine-foam ephantsi zine-cloud point ephantsi.
Indawo Yokuqandisa Ethontsiweyo: Njengoko iziphelo ze-hydrophilic zivalwe ngamaqela e-lipophilic okanye amaqela e-lipophilic, amandla e-intermolecular ayabuthathaka, nto leyo ebangela ukuba i-frozen point ibe sezantsi. Le propati yenza kube lula ukusetyenziswa kwemveliso enjalo.
Ukuthambekela kokwenza iijeli emanzini: Ezi mveliso zibonisa ukuthambekela okuncinci kakhulu kokwenza iijeli emanzini, nto leyo eluncedo kakhulu ekubunjweni kwemveliso.
Ukusetyenziswa kwee-Surfactants eziphantsi kwe-Foam kwiUkucoca iiShishini
Izixhobo zetafile Ukucoca kwangaphambili: Ngokuqhelekileyo kubhekisa kwizinto zetafile ezihlanjwa ngaphambi kokuba zifakwe kwisitya sokuhlamba izitya.
Ukucoca-kwiNdawo: Ngokuyintloko kubhekisa kwinkqubo yokucoca ngexesha lokuveliswa kokutya kunye nokucubungula. Kwinkqubo yokucoca, umsebenzi oyintloko we-surfactants kukumanzisa. Okwangoku, ii-surfactants ezisetyenziswa kwiimveliso zokucoca zezo zingenamagwebu aphantsi ezineempawu zokususa ifoam kunye nokuthintela ifoam, eziqinisekisa inkqubela phambili ethe tye kwimisebenzi yokucoca.
Ukucocwa kweebhotile zesiselo ezisetyenzisiweyo: Kugxile ekucocweni kweebhotile zebhiya ezisetyenzisiweyo.
Ukucocwa kwesinyithi: Ekucoceni isinyithi, ii-surfactants azenzi nje kuphela imisebenzi yokumanzisa, ukususa ivumba kunye nokuthintela i-foam, kodwa zikwafuna ukunika i-detergent enamandla. Ukongeza, amabala eoyile anokubangela ukuveliswa kwe-foam eninzi kwinkqubo njengoko ukucoca kuqhubeka. Ke ngoko, ii-surfactants kufuneka zibe ne-detergent egqwesileyo, zibe ne-foam ephantsi, kwaye zithintele i-foam ebangelwa zizinto ezingcolisayo yeoyile.
