Chizvarwa chechitatu defoamer ndeye silicone defoamer yakavakirwa polydimethylsiloxane (PDMS, dimethyl silicone mafuta).Parizvino, kutsvagisa uye kushandiswa kweichi chizvarwa che defoamers kwakanyatso kunangana muChina.PDMS inoumbwa nesilicon okisijeni cheni uye mamwe organic mapoka, uye haigone kurongeka zvakasimba pane furo remvura firimu, kuitira kuti mabhuru aputika.Low viscosity PDMS ine yakanaka defoaming pfuma uye yakakwirira viscosity PDMS ine yakanaka defoaming pfuma.
Zvakanakira silicone defoamer
Iine inertia yakanaka yemakemikari uye yakaoma kuita nezvimwe zvinhu.Inogona kushandiswa mu acid, alkali uye munyu mhinduro.
Yakanaka physiological inertia, inogona kushandiswa mumaindasitiri ezvekudya uye emishonga, uye haina kusvibiswa kune zvakatipoteredza.
Iine kugadzikana kwakanaka kwekupisa uye kuderera kwakadzika, uye inogona kushandiswa muhupamhi hwekushisa.
Iyo viscosity yakaderera uye inopararira nekukurumidza kune gasi-mvura yemvura interface.
Surface tension yakaderera se 1.5-20 Mn / M (76 Mn / m yemvura).
Hazvisi nyore kunyungudutswa ne surfactant mu furo system.
Yakaderera dosage, yakaderera viscosity uye yakaderera kupisa.
Kuipa kwesilicone defoamer
1. Zvakaoma kupararira muhurongwa hwemvura.
2. Nemhaka yekuti inonyungudika mumafuta, iyo inosvibisa maitiro muoiri system inoderedzwa.
3. Kusagadzikana kwekushisa kwepamusoro.
4. Kusagadzikana kupikisa kune alkalinity yakasimba.
Mutengo wepamusoro:PDMS imvura iri mumafuta (O/W) emulsion yakagadzirwa nesilicone girisi, emulsifier, thickener, nezvimwewo, iyo inonatswa nemvura.Iko kushushikana kwepamusoro kunodzikira nekukurumidza uye kune yakasimba anti furo uye anti furo mhedzisiro.Iyo yakakamurwa kuita matatu magadzirirwo: silicone mafuta, silicone mafuta + yakagadziridzwa polyether uye polyether yakagadziridzwa silicone mafuta.
Inoratidzwa ne:Kudzika kwepasi tension, yakakwirira pamusoro pekuita uye yakasimba defoaming simba.
Mushonga mushoma:Inogona kuvharidzira nekupwanya mabubble kune akawanda bubble media.Iine kugadzikana kwakanaka kwekushisa uye inogona kushandiswa muhupamhi hwekushisa.Inogovaniswa nepolyether uye ine synergistic effect.Inoshandiswa zvakanyanya kusvibisa detergent, papermaking, pulp, shuga kugadzira, electroplating, makemikari fetiraiza, additives, tsvina yemvura uye mamwe maitiro ekugadzira.Muindasitiri yepetroleum, inoshandiswa zvakanyanya pa desulfurization yegasi rechisikigo kuti ikurumidze kuparadzaniswa kwemafuta-gasi;Inoshandiswawo kudzora kana kudzvanyirira mabubble mumidziyo yakaita se ethylene glycol kuomesa, inonhuhwirira hydrocarbon kudhirowa, asphalt kugadzirisa uye yekuzora mafuta dewaxing.Muindasitiri yemachira, inoshandiswa pakubvisa furo mukudhaya, kukwesha, saizi uye mamwe maitiro;Inoshandiswa mukuita kwemakemikari emulsion uye defoaming muindasitiri;Iyo inoshandiswa pakubvisa furo mune dzakasiyana siyana, kuvirisa uye distillation maitiro muindasitiri yechikafu.
