Igisekuru cya gatatu defoamer ni defoamer ya silicone ishingiye kuri polydimethylsiloxane (PDMS, amavuta ya silicone ya dimethyl).Kugeza ubu, ubushakashatsi nogukoresha iki gisekuru cya defoamers byibanda mubushinwa.PDMS igizwe numuyoboro wa ogisijeni wa silicon hamwe nandi matsinda kama, kandi ntishobora gutondekwa neza kuri firime yamazi ya furo, kugirango ibibyimba biturika.Ubucucike buke PDMS ifite umutungo mwiza wo gusebanya kandi ubwiza bwinshi PDMS ifite umutungo mwiza wo gusebanya.
Ibyiza bya silicone defoamer
Ifite inertia nziza yimiti kandi biragoye kubyitwaramo nibindi bintu.Irashobora gukoreshwa muri acide, alkali hamwe numuti wumunyu.
Inertia nziza yumubiri, irashobora gukoreshwa mubiribwa ninganda zimiti, kandi nta mwanda uhumanya ibidukikije.
Ifite ubushyuhe bwiza nubushyuhe buke, kandi irashobora gukoreshwa mubushuhe bugari.
Ubukonje buri hasi kandi bukwirakwira vuba kuri gazi-yamazi.
Ubushyuhe bwo hejuru bugera kuri 1.5-20 Mn / M (76 Mn / m kumazi).
Ntibyoroshye gukemurwa na surfactant muri sisitemu yo kubira ifuro.
Igipimo gito, ubukonje buke hamwe no gucana umuriro.
Ibibi bya silicone defoamer
1. Biragoye gutatanya muri sisitemu y'amazi.
2. Kuberako ibora mumavuta, ingaruka zo gusebanya muri sisitemu ya peteroli ziragabanuka.
3. Kurwanya ubushyuhe buke.
4. Kurwanya nabi alkalinity.
Igiciro kinini:PDMS ni amazi mumavuta (O / W) emulisiyo ikozwe mumavuta ya silicone, emulisiferi, umubyimba, nibindi, bigasukurwa namazi.Ubushyuhe bwo hejuru bugabanuka vuba kandi bufite ingaruka zikomeye zo kurwanya ifuro no kurwanya ifuro.Igabanijwemo ibice bitatu: amavuta ya silicone, amavuta ya silicone + yahinduwe polyether hamwe namavuta ya silicone yahinduwe.
Irangwa na:Ubushyuhe buke bwo hejuru, ibikorwa byo hejuru hamwe nimbaraga zikomeye zo gusebanya.
Igipimo gito:Irashobora guhagarika no kumena ibituba kubitangazamakuru byinshi.Ifite ubushyuhe bwiza kandi irashobora gukoreshwa mubushuhe bugari.Irasangiwe na polyether kandi ifite ingaruka zo guhuza.Ikoreshwa cyane mugusebanya, kumena impapuro, gukora impapuro, gukora isukari, amashanyarazi, ifumbire mvaruganda, inyongeramusaruro, gutunganya amazi mabi nibindi bikorwa.Mu nganda za peteroli, ikoreshwa cyane mu gusohora gaze gasanzwe kugirango yihutishe gutandukanya gaze na gaze;Irakoreshwa kandi mu kugenzura cyangwa guhagarika ibituba mu bikoresho nko gukama Ethylene glycol, gukuramo hydrocarubone ya aromatic, gutunganya asfalt no gusiga amavuta amavuta.Mu nganda z’imyenda, ikoreshwa mu gusebanya mu gusiga irangi, gusaka, ubunini n'ibindi bikorwa;Ikoreshwa mugikorwa cyo gusohora imiti no gusebanya mu nganda;Ikoreshwa mugusebanya muburyo butandukanye, fermentation hamwe na distillation mubikorwa byinganda.
