Hariho ubwoko bwinshi bwaAbasebanyakandi bikoreshwa cyane. Uburyo bwo "guhagarika ifuro" no "gucika kw'ifuro" bya defoamer ni: iyo defoamer yongewe muri sisitemu, molekile zayo zikwirakwizwa ku buryo butunguranye hejuru y'amazi, bibuza ikorwa rya firime irabagirana, ni ukuvuga guhagarika ikorwa rya foam. Iyo sisitemu ikora ifuro rinini, ongeramo defoamer, molekile zayo zihita zikwirakwira hejuru y'ifuro, zigakwirakwira vuba, zigakora urwego rw'ifilimi ebyiri nto cyane, zigakwirakwira cyane, zigacengera, zigakwirakwira mu byiciro, bityo zigasimbuza urukuta rworoshye rwa firime ya foam ya mbere. Kubera ko ifite ubushyuhe buke, itembera mu mazi ifite ubushyuhe bwinshi butanga ifuro, bityo molekile za defoamer zifite ubushyuhe buke bukomeza gukwirakwira no kwinjira hagati y'aho gazi n'amazi bihurira, bigatuma urukuta rwa firime rugabanuka vuba, kandi ifuro naryo rigirwaho ingaruka n'ubuso buyikikije. Urukuta rwa firime rufite ubushyuhe bwinshi rurakurura cyane, ku buryo ubushyuhe bukikije ifuro budakwirakwira, bigatuma "ifuro ricika". Molekile za defoamer zidashongeshwa muri sisitemu zizongera kwinjira mu rundi ruziga rwa foam, bityo, foam yose izasenyuka burundu.
Uburyo bwo guhitamo nezaUmuti wo kurwanya ifuro
Gukora no kubaka irangi bizatanga irangi ku rugero rutandukanye. Gukora irangi bibangamira iterambere ry’umusaruro n’ubwubatsi, kandi icyarimwe bigatera inenge kuri firime irangiye yo gusiga. Guhitamo neza icyuma gisukura gikwiye bishobora kwemeza iterambere risanzwe ry’umusaruro n’ubwubatsi.
Inshingano y'icyuma gikuraho amazi: gusenya icyuma gitwikira amazi kiri ku buso bw'icyuma gikuraho amazi, gukumira ko iki gikuraho amazi kirema kandi kigatuma iki gikuraho amazi kigabanuka. Igikoresho gikuraho amazi kikoreshwa ku bice binini, kandi microfoam igomba gukoreshwa hamwe no gukuramo imyuka no gukuramo amazi.
Ibiranga Defoamer: Defoamer ntishongera mu buryo bw'umwuka, ariko ishobora kwinjira no gukwirakwira mu buryo bw'utudomo duto. Ubugari bwiza bw'utudomo duto twa defoamer bungana n'ubugari bw'urukuta rw'ifuro.
Imiterere ya Defoamer:Abasebanyaku byerekeye irangi ry’inyubako rishingiye ku mazi rigabanyijemo ubwoko butari ubwa silikoni n’uburimo silikoni.Abasebanyazigizwe n'ibi bikurikira:
Ibikoresho bikora: Bikora nk'ikintu gica ifuro kandi gikuraho ubushyuhe bufite ubushyuhe buke. Ibikubiye muri byo birimo amavuta y'inyamaswa n'ibimera, silica idafite amazi, alkoholi nyinshi, nibindi.
Uburyo bwo gukwirakwiza: Gutosesha emulsifier kugira ngo utwo dutonyanga duto dukwirakwira kandi tugakora kuri firime y'ibibuno hanyuma tugakwirakwira. Harimo eteri ya phenol polyoxyethylene itari (octyl), umunyu w'isabune n'ibindi.
Umuyoboro: Ifasha ikintu gikora guhuzwa n'uburyo bwo gusohora ifuro, kandi biroroshye gukwirakwira mu buryo bwo gusohora ifuro. Iyo ukoresheje byombi, ifite ubushyuhe buke, ifasha mu gukumira ifuro, kandi ishobora kugabanya ikiguzi.
Ibisabwa bibiri bigomba kubahirizwa kugira ngo habeho isuku: urwego rwo kwinjira: E=γ1+γ12-γ3 > 0, kugira ngo hamenyekane ko isuku yinjira mu rukuta rw'ifuro; urwego rwo gukwirakwiza S=γ1-v12-γ3 >0, kugira ngo hamenyekane ko isuku itonyanga.
