Chii chinonzi Silicone Antifoam

MaSilicone antifoams anowanzo gadzirwa ne hydrophobic silica inoparadzirwa zvakanaka mukati me silicone fluid. Musanganiswa unobuda unozogadziriswa kuita emulsion ine mvura kana mafuta. Ma antifoams aya anoshanda zvakanyanya nekuda kwekusashanda kwawo kwemakemikari, simba kunyangwe kana ari mashoma, uye kugona kupararira pamusoro pefirimu refuro. Kana zvichidikanwa, anogona kusanganiswa nezvimwe zvinhu zvakasimba zve hydrophobic uye zvinwiwa kuti zvivandudze hunhu hwazvo hwekusvibisa.

Mishonga inorwisa furo inonzi silicone ndiyo inowanzo shandiswa. Inoshanda nekupwanya kusimba kwenzvimbo uye kudzikamisa mabubble efuro, zvichiita kuti iparare. Izvi zvinobatsira kubvisa furo riripo nekukurumidza uye zvinobatsirawo kudzivirira kuumbwa kwefuro.

Mabhenefiti eSilicone Defoamer

• Mhando dzakasiyana dzemashandisirwo

Nekuda kwechimiro chemakemikari chemafuta esilicone, haishande nemvura kana zvinhu zvine mapoka epolar, kana nemahydrocarbon kana zvinhu zve organic zvine mapoka ehydrocarbon. Sezvo mafuta esilicone asinganyungudike muzvinhu zvakawanda, silicone defoamer ine mashandisirwo akasiyana-siyana. Inogona kushandiswa kwete chete pakugadzira masisitimu emvura, asiwo pakugadzira masisitimu emafuta.

• Kusimba kwepasi kwakaderera

Kusimba kwemafuta esilicone kunowanzova 20-21 dynes/cm uye kudiki pane simba remvura (72 dynes/cm) uye zvinwiwa zvinofema, izvo zvinovandudza simba rekudzora furo.

• Kugadzikana kwakanaka kwekupisa

Tichitora semuenzaniso wemafuta e dimethyl silicone anoshandiswa zvakanyanya, kuramba kwayo kupisa kwenguva refu kunogona kusvika 150°C, uye kuramba kwayo kupisa kwenguva pfupi kunogona kusvika pamusoro pe300°C, zvichiita kuti silicone defoaming agents ishandiswe pakupisa kwakakura.

• Kugadzikana kwakanaka kwemakemikari

Oiri yesilicone ine kugadzikana kwakanyanya kwemakemikari uye inonetsa kubatanidzwa nemakemikari nezvimwe zvinhu. Saka, chero bedzi chigadzirwa chacho chiri chakanaka, mishonga inobvisa mabhakitiriya inobvumirwa kushandiswa muzvinhu zvine acids, alkalis, uye munyu.

• Kusasimba kwemuviri

Oiri yeSilicone yakaratidzwa kuti haina chepfu kuvanhu nemhuka. Saka, ma silicone defoamers (ane ma emulsifiers asina chepfu, nezvimwewo) anogona kushandiswa zvakachengeteka mu pulp nebepa, kugadzira chikafu, kurapa, mishonga uye maindasitiri ekushongedza.

• Kusvibisa zita zvine simba

MaSilicone defoamers haangogone kupwanya furo risingadiwe chete, asiwo kudzivirira furo zvakanyanya uye kudzivirira kuumbwa kwefuro. Chiyero chacho chidiki kwazvo, uye chikamu chimwe chete chemiriyoni (1 ppm kana 1 g/m3) chehuremu hwechinhu chinopupuma furo chinogona kuwedzerwa kuti chibudise mhedzisiro yekupupuma furo. Huwandu hwayo hwakafanana i1 kusvika 100 ppm. Mutengo wayo hausi wepamusoro chete, asi hauzosvibisi zvinhu zviri kupupuma furo.

Ma silicone antifoam anokosheswa nekuda kwekugadzikana kwawo, kushanda kwawo nezvinhu zvakasiyana-siyana, uye kushanda kwawo muhuwandu hushoma. Zvisinei, zvakakosha kuve nechokwadi chekuti anotevedzera mitemo yepamutemo uye akakodzera kushandiswa kwawo kudzivirira chero mhedzisiro yakaipa pamhando yechigadzirwa kana nharaunda.
