Chii chinonzi Silicone Antifoam

Silicone antifoams inowanzo umbwa ne hydrophobized silica iyo inoparadzirwa zvakanaka mukati mesilicone fluid.Mushonga unoguma unobva wagadziriswa mumvura-based kana mafuta-based emulsion.Aya antifoams anoshanda zvakanyanya nekuda kweakajairwa makemikari inertness, potency kunyangwe mukudzika kwakadzika, uye kugona kupararira pamusoro pefuro firimu.Kana zvichidikanwa, zvinogona kusanganiswa nemamwe mahydrophobic solids uye zvinwiwa kuti zvivandudze zvimiro zvavo zvekubvisa furo.

Silicone antifoam agents inowanzosarudzwa.Vanoshanda nekupwanya kusawirirana kwepasi uye kukanganisa furo furo, zvichiita kuti vapunzike.Chiito ichi chinobatsira kubvisa furo nekukurumidza uye chinobatsira kudzivirira kuumbwa kwefuro.

Zvakanakira silicone defoamer

• Wide siyana mafomu

Nekuda kwechimiro chakakosha chemakemikari esilicone oiri, haienderane nemvura kana zvinhu zvine mapoka epolar, kana nemahydrocarbon kana organic zvinhu zvine mapoka ehydrocarbon.Sezvo mafuta e-silicone asingasviki muzvinhu zvakawanda, silicone defoamer ine zvakasiyana-siyana zvekushandisa.Inogona kushandiswa kwete chete kusvibisa masisitimu emvura, asiwo kune defoaming oiri masisitimu.

• Kuderera kwepasi pasi

Iko kunetsana kwepamusoro kwesilicone oiri kunowanzo kuve 20-21 dynes/cm uye idiki pane tension yemvura (72 dynes/cm) uye zvinwiwa zvinopupuma furo, izvo zvinovandudza kudzora furo.

• Kugadzikana kwakanaka kwekushisa

Kutora inowanzo shandiswa dimethyl silicone oiri semuenzaniso, iyo yenguva refu tembiricha yekudzivirira inogona kusvika 150 ° C, uye yayo yenguva pfupi yekupisa tembiricha inogona kusvika pamusoro pe300 ° C, kuve nechokwadi chekuti silicone defoaming agents inogona kushandiswa munzvimbo yakakura yekupisa.

• Kugadzikana kwakanaka kwemakemikari

Mafuta eSilicone ane kugadzikana kwemakemikari akakwirira uye zvakaoma kuita makemikari nezvimwe zvinhu.Nokudaro, chero bedzi gadziriro yacho ine musoro, silicone defoaming agents inobvumirwa kushandiswa mumasitimu ane acids, alkali, uye munyu.

• Physiological inertia

Silicone mafuta yakaratidza kuti haina chepfu kuvanhu nemhuka.Naizvozvo, silicone defoamers (ine yakakodzera isiri-chepfu emulsifiers, nezvimwewo) inogona kushandiswa zvakachengeteka mu pulp uye bepa, kugadzira chikafu, kurapwa, mishonga uye cosmetic maindasitiri maapplication.

• Kubvisa furo kune simba

Silicone defoamers haingogone kuputsa furo iripo isingadikanwi, asiwo inodzivirira zvakanyanya furo uye kudzivirira kuumbwa kwefuro.Muyero wacho idiki zvakanyanya, uye chikamu chimwe chete chemiriyoni (1 ppm kana 1 g/m3) chehuremu hwemhepo inopupuma inogona kuwedzerwa kuti ibudise furo.Iyo yakajairika chiyero ndeye 1 kusvika 100 ppm.Haisi iyo chete mutengo wakaderera, asi haizosvibisa zvinhu zviri kusvibiswa.

Silicone antifoams inokosheswa nekugadzikana kwayo, kuenderana nezvinhu zvakasiyana, uye kushanda muyakadzika.Nekudaro, zvakakosha kuve nechokwadi kuti vanoteedzera zvimiro uye vakakodzera kune chaiyo application kudzivirira chero yakaipa mhedzisiro pamhando yechigadzirwa kana nharaunda.
