I-defoamer yesizukulwane sesithathu i-silicone defoamer esekelwe ku-polydimethylsiloxane (PDMS, i-dimethyl silicone oil).Njengamanje, ucwaningo kanye nokusetshenziswa kwalesi sizukulwane sama-defoamers kugxile eChina.I-PDMS yakhiwe iketango le-silicon oxygen namanye amaqembu ezinto eziphilayo, futhi ayikwazi ukuhlelwa ngokuqinile efilimini ye-foam liquid, ukuze amabhamuza aqhume.I-PDMS ye-viscosity ephansi inendawo enhle yokuqeda ugwebu kanye ne-viscosity ephezulu ye-PDMS inendawo enhle yokukhipha amagwebu.
Izinzuzo ze-silicone defoamer
Ine-inertia yamakhemikhali enhle futhi kunzima ukusabela nezinye izinto.Ingasetshenziselwa izixazululo ze-asidi, i-alkali nosawoti.
I-inertia enhle ye-physiological, ingasetshenziswa ezimbonini zokudla kanye nemithi, futhi ayinakho ukungcoliswa kwemvelo.
Inokuqina okuhle kokushisa kanye nokuguquguquka okuphansi, futhi ingasetshenziswa ebangeni lokushisa elibanzi.
I-viscosity iphansi futhi isakazeka ngokushesha ku-interface ye-gas-liquid.
Ukushuba kobuso kuze kufike ku-1.5-20 Mn/M (76 Mn/m ngamanzi).
Akulula ukuncibilika nge-surfactant ohlelweni olugcwele amagwebu.
Umthamo ophansi, i-viscosity ephansi kanye nokuvutha okuphansi.
Ukungalungi kwe-silicone defoamer
1. Kunzima ukuhlakazeka ohlelweni lwamanzi.
2. Ngenxa yokuthi iyancibilika emafutheni, umphumela wokukhipha amagwebu ohlelweni lwamafutha uyancishiswa.
3. Ukumelana nezinga lokushisa eliphansi.
4. Ukumelana okungalungile ne-alkalinity enamandla.
Izindleko eziphezulu:I-PDMS i-emulsion yamanzi kuwoyela (O/W) eyenziwe ngamafutha e-silicone, i-emulsifier, i-thickener, njll., efakwe emanzini.Ukushuba kwendawo kuncipha ngokushesha futhi kunemiphumela eqinile yokunqanda ukugwedla kanye ne-anti-foaming.Icishe ihlukaniswe yaba izingxenye ezintathu: uwoyela we-silicone, uwoyela we-silicone + i-polyether eguquliwe kanye namafutha e-silicone ashintshiwe nge-polyether.
Ibonakala ngokuthi:Ukushuba kwesimo esiphansi, ukusebenza kwendawo ephezulu namandla aqinile okuqeda amagwebu.
Umthamo omncane:Ingavimbela futhi iphule amabhamuza kumidiya yebhamuza eminingi.Inokuqina okuhle kokushisa futhi ingasetshenziswa ebangeni elibanzi lokushisa.Yabelwe nge-polyether futhi inomphumela we-synergistic.Isetshenziselwa kakhulu ukukhipha amagwebu ku-detergent, papermaking, pulp, sugar making, electroplating, chemical fertilizer, izithasiselo, ukwelashwa kwamanzi angcolile nezinye izinqubo zokukhiqiza.Embonini ye-petroleum, isetshenziswa kabanzi ukukhipha i-desulfurization yegesi yemvelo ukusheshisa ukuhlukaniswa kwegesi kawoyela;Iphinde isetshenziselwe ukulawula noma ukucindezela amabhamuza kumadivayisi afana nokomisa kwe-ethylene glycol, ukukhishwa kwe-hydrocarbon enephunga elimnandi, ukucutshungulwa kwe-asphalt kanye ne-lubricating oil dewaxing.Embonini yendwangu, isetshenziselwa ukukhipha amagwebu ekudayeni, ukukhuhla, ukulinganisa nezinye izinqubo;Isetshenziselwa inqubo ye-emulsion yamakhemikhali kanye ne-defoaming embonini;Isetshenziselwa ukukhipha amagwebu ezinqubweni ezihlukahlukene zokuhlushwa, ukuvutshelwa kanye ne-distillation embonini yokudla.
