Chii chinonzi Antifoam mukurapa mvura yakasviba?

Antifuro, inozivikanwawo se defoamer, chinhu chinoshandiswa mukurapa mvura yakasviba kudzora kuumbwa kwefuro. Furo idambudziko rinowanzoitika mumiti yekurapa mvura yakasviba uye rinogona kubva munzvimbo dzakasiyana-siyana dzakadai sezvinhu zvakasikwa, ma surfactants, kana kumutswa kwemvura. Kunyange zvazvo furo ringaita serisina njodzi, rinogona kukanganisa kushanda zvakanaka kwekurapa mvura yakasviba nekuvhiringidza mashandiro emidziyo, kuderedza kushanda kwemishonga yemakemikari, uye zvinogona kukonzera matambudziko ekuzara kana kutakurwa kwezvinhu.

Mishonga inorwisa furo inoshanda nekukanganisa mabubble efuro, zvichiita kuti aputsike kana kubatana, nokudaro ichideredza huwandu hwefuro uye ichidzivirira kuti isakanganise maitiro ekurapa. Mishonga iyi inowanzova nemusanganiswa wezvinhu zvinosvibisa, mafuta, silicones, kana zvimwe zvinhu zvinosvibisa mvura. Kana zvawedzerwa mumvura yakasviba, mishonga inorwisa furo inotamira pamusoro pefuro uye inovhiringidza kusimba kwenzvimbo, zvichikonzera kuputika kwemabubble efuro.

Kune mhando dzakasiyana dzemishonga inodzivirira furo dzinoshandiswa mukurapa mvura yakasviba, imwe neimwe ine hunhu hwayo uye mashandisirwo ayo:

Mishonga inorwisa furo inobva kuSilicone:

Izvi ndezvimwe zvezvinonyanya kushandiswa pakurapa furo nekuda kwekushanda kwazvo mumamiriro akasiyana-siyana. Zvinodzivirira furo zvakagadzirwa nesilicone zvakagadzikana, hazvinyungudike mumvura, uye zvinogona kugadzirwa kuti zvienderane nemaitiro akasiyana-siyana ekurapa mvura yakasviba.

Mabhenefiti e organosilicon defoamers:

Kusashanda zvakanaka kwemakemikari, kwete kusangana nezvimwe zvinhu, kunogona kushandiswa mu acidic, alkaline, uye munyu.

Kusashanda zvakanaka kwemuviri, kwakakodzera kushandiswa muindasitiri yechikafu nemishonga, uye hakuna kusvibiswa kwenharaunda

Kugadzikana kwekupisa kuri pakati nepakati, kusagadzikana kwakaderera, uye kunogona kushandiswa pakupisa kwakasiyana-siyana

Kusviba kwakaderera, kupararira nekukurumidza pa gas-liquid interface

Kusimba kwemvura kwakaderera kusvika 1.5-20 mN/m (mvura 76 mN/m)

Hainyungudike muzvinhu zvinoshandisa furo

Chipimo chidiki, viscosity yakaderera, uye kupisa kwakaderera

Mishonga inorwisa furo inonzi polymeric:

Mishonga iyi inorwisa furo inobva pamapolymers anokanganisa kuumbwa kwefuro nekunamira pamusoro pemabubbles efuro uye kuchinja kugadzikana kwawo. Mishonga inorwisa furo yePolymeric inowanzo shandiswa mumamiriro ezvinhu apo mishonga yechinyakare inorwisa furo ingave isingashande, senge mumvura ine alkaline yakawanda kana acidic.

Zvimwe zvinodzivirira furo:

Mune zvimwe zviitiko, ma antifoams akagadzirwa nesilicone angasakodzera nekuda kwezvinetso zvetekinoroji kana zvinodiwa pakuita zvinhu. Ma antifoams asiri esilicone, akadai se mineral oil-based kana fatty acid-based antifoams, anopa dzimwe nzira dzinogona kunge dzisina njodzi kune zvakatipoteredza kana kuti dzakakodzera mamwe mashandisirwo.

Mishonga yekudzivirira furo yakapfurwa:

Mimwe mishonga inorwisa furo inowanikwa muchimiro cheupfu, izvo zvinogona kubatsira kana zvikashandiswa kana zvikasashanda kana kuti zvichidikanwa kuti pave nekushanda kwenguva refu kwemishonga inorwisa furo.

Kusarudzwa kwemushonga unodzivirira furo unokodzera kunoenderana nezvinhu zvakaita semhando yemvura yakasviba, maitiro chaiwo ekurapa ari kushandiswa, zvinodiwa nemitemo, uye kufunga nezvemitengo. Pamusoro pekusarudza mushonga unodzivirira furo wakakodzera, chiyero chakakodzera uye nzira dzekushandisa dzakakosha kuve nechokwadi chekuti furo rinodzorwa zvakanaka pasina kukanganisa mashandiro ekurapa mvura yakasviba.

Kunyange zvazvo mishonga inorwisa furo ichibudirira mukudzora furo mukurapa mvura yakasviba, zvakakosha kuishandisa nokuchenjera kudzivirira migumisiro isingatarisirwi yakadai sekupindira mukurapa kwemuviri kana kuburitswa kwezvinhu zvinokuvadza munzvimbo yakapoteredza. Kugara uchitarisa huwandu hwefuro uye kugadzirisa chiyero chefuro sezvinodiwa kunogona kubatsira kugadzirisa kudzora furo uku uchideredza chero kukanganisa kwakaipa pakushanda zvakanaka kwekurapa mvura yakasviba uye kutevedzera mitemo yezvakatipoteredza.
