Chii chinonzi Antifoam mukurapa kwemvura yakasviba?

Antifoam, inozivikanwawo se defoamer, ikemikari yekuwedzera inoshandiswa mumararamiro ekuchenesa mvura kudzora kuumbwa kwefuro.Furo inyaya yakajairika mumidziyo yekuchenesa mvura uye inogona kubuda kubva kwakasiyana siyana senge organic matter, surfactants, kana kubvongodzwa kwemvura.Nepo furo ringaite serisingakuvadzi, rinogona kukanganisa kushanda kwemvura yetsvina nekukanganisa kushanda kwemidziyo, kuderedza kushanda kwemishonga yemakemikari, uye zvinogona kukonzera mafashama kana nyaya dzekutakura.

Antifoam agents anoshanda nekudzikamisa furo furo, zvichiita kuti adonhe kana kubatana, nekudaro achidzikisa huro hwefuro uye kudzivirira kuvhiringa maitiro ekurapa.Aya maajenti anowanzo sanganisira musanganiswa weano surfactants, oiri, silicones, kana zvimwe hydrophobic zvinhu.Kana yakawedzerwa kumvura yakasvibiswa, antifoam agents anotamira kumusoro kwefuro uye anovhiringidza kukanganiswa kwepamusoro, zvichiita kuti pave nekuputika kwefuro bubbles.

Kune akati wandei marudzi eantifoam agents anoshandiswa mukuchenesa mvura yetsvina, imwe neimwe iine yayo chaiyo zvivakwa uye mashandisiro:

Silicone-based antifoams:

Aya ari pakati peanonyanya kushandiswa antifoam ejenti nekuda kwekushanda kwawo mumhando dzakasiyana dzemamiriro.Silicone-based antifoams yakagadzikana, isinganyungudika mumvura, uye inogona kugadzirwa kuti ienderane neyakasiyana nzira yekuchenesa mvura.

Zvakanakira zve organosilicon defoamers:

Yakanaka makemikari inertness, kwete kuita nezvimwe zvinhu, inogona kushandiswa mune acidic, alkaline, uye munyu masisitimu.

Yakanaka physiological inertness, yakakodzera kushandiswa mumaindasitiri ezvekudya uye emishonga, isina kusvibiswa kune zvakatipoteredza.

Moderate thermal kugadzikana, yakaderera volatility, uye inogona kushandiswa pamusoro pehupamhi hwekushisa renji

Low viscosity, inokurumidza kupararira pagasi-mvura yemvura interface

Kushushikana kwepamusoro kwakadzikira se1.5-20 mN/m (mvura iri 76 mN/m)

Kwete soluble mune surfactants of foaming systems

Yakaderera dosage, yakaderera viscosity, uye yakaderera kupisa

Polymeric antifoams:

Aya antifoam agents akavakirwa pamapolymer anovhiringidza kuumbwa kwefuro nekushambadza pamusoro pemafuro efuro uye nekuchinja kugadzikana kwawo.Polymeric antifoams inowanzoshandiswa mumamiriro ezvinhu apo echinyakare antifoam maajenti anogona kusashanda, senge mune yakanyanya alkaline kana acidic tsvina yemvura.

Mamwe antifoams:

Mune zvimwe zviitiko, silicone-based antifoams inogona kunge isingakodzeri nekuda kwekunetsekana kwetekinoroji kana chaiwo maitiro ezvinodiwa.Non-silicone antifoams, senge mineral oil-based or fatty acid-based antifoams, inopa dzimwe nzira dzinogona kunge dzakanyanya kushamwaridzana kana kuti dzakanyatsokodzera kune mamwe maitiro.

Powdered antifoams:

Mamwe maantifoam maajenti anowanikwa ari muupfu, izvo zvinogona kubatsira mumashandisirwo apo mvura yekuwedzera isingashande kana kunodiwa kwenguva yakareba antifoam chiitiko.

Kusarudzwa kweakakodzera antifoam mumiririri kunoenderana nezvinhu zvakaita semhando yemvura yetsvina, maitiro chaiwo ekurapa ari kushandiswa, zvinodikanwa zvemitemo, uye kufunga kwemitengo.Pamusoro pekusarudza iyo chaiyo antifoam mumiriri, dosi chaiyo uye nzira dzekushandisa dzakakosha kuti uve nechokwadi chekudzora furo pasina kukanganisa kuita kwemvura yetsvina.

Nepo antifoam vamiririri vari kushanda mukudzora furo mumararamiro ekuchenesa mvura, zvakakosha kuti uzvishandise zvine hungwaru kudzivirira mhedzisiro isingatarisirwe sekukanganisa maitiro ekurapa kwebiology kana kuburitswa kwezvinhu zvinokuvadza munzvimbo.Kugara uchitarisisa mazinga efuro uye kugadziridzwa kweantifoam dosage sezvinodiwa kunogona kubatsira kukwenenzvera kudzora furo uku uchidzikisa chero kukanganisa kunokanganisa kushanda kwemvura yetsvina uye kutevedzera kwezvakatipoteredza.
