Ma defoamers muMashandisirwo Emaindasitiri

Zvinosvibisa zita remunhuzvakakosha mukushandiswa kwemaindasitiri. Maitiro mazhinji emaindasitiri anogadzira furo, kungave kuri kukanganiswa kwemakemikari kana kuti reaction yemakemikari. Kana ikasadzorwa uye ikasarapwa, inogona kukonzera matambudziko akakomba.

Furo rinoumbwa nekuda kwekuvapo kwemakemikoro e surfactant mumvura, ayo anodzikamisa mabubbles, zvichikonzera kuumbwa kwefuro. Basa revanobvisa furo nderekutsiva makemikari aya e surfactant, zvichiita kuti mabubbles aputika uye furo riderere.

Ndedzipi mhando huru dzefuro?

Foam yeBiofoam ne surfactant:

Biofoam inogadzirwa netupukanana kana ikachinja nekuora zvinhu zvipenyu mumvura yakasviba. Biofoam ine maburi madiki akatenderera, yakasimba, uye inoita kunge yakaoma.

Furo rinoputika rinokonzerwa nekuwedzerwa kwezvinoshandiswa pakugadzira zvinhu zvakaita sesipo nesipo, kana kuti nekuita kwezvinhu zvinoparadza nemafuta kana mafuta nezvimwe makemikari.

Ma defoamers anoshanda sei?

Ma defoamers anodzivirira kuumbwa kwefuro nekuchinja hunhu hwemvura. Ma defoamers anotsiva mamorekuru e surfactant muchikamu chakatetepa chefuro, zvinoreva kuti chikamu chimwe chete hachina kusimba uye chinogona kutyoka.

Ungasarudza sei defoamer?

Ma defoamers anowanzo kamurwa kuita ma defoamers akavakirwa pa silicone uye ma defoamers asina silicone. Sarudzo ye defoamer inoenderana nezvinodiwa nemamiriro ekushandiswa kwacho. Ma defoamers akavakirwa pa silicone anoshanda pasi pe pH yakasiyana-siyana nemamiriro ekupisa uye anowanzo kufarirwa nekuda kwekugadzikana kwawo uye kushanda kwawo zvakanaka. Ma defoamers asina silicone anoshandiswa zvakanyanya kubva pama organic compounds akadai se fatty amides, sipo dzesimbi, fatty alcohols, uye fatty acid esters. Zvakanakira ma non-silicone systems i diffusion coefficients yakakura uye foam breaking ability yakasimba; dambudziko guru nderekuti foam depressure ability haina kunaka nekuda kwekumanikidzwa kwepamusoro kupfuura silicone.

Pakusarudza defoamer yakakodzera, zvinhu zvakaita serudzi rwesystem, mamiriro ekushanda (tembiricha, pH, kumanikidzwa), kuenderana kwemakemikari, uye zvinodiwa nemitemo zvinofanirwa kutariswa. Nekusarudza defoamer yakakodzera, indasitiri inogona kugadzirisa matambudziko ane chekuita nefuro uye kuvandudza mashandiro ese.

Ndirini panodiwa mushonga wekubvisa manyoka mumvura?

Panguva yekuchenesa mvura, panowanzova nemamiriro ezvinhu anokonzera furo, akadai sekumutswa kwemvura, kuburitswa kwemagasi akanyungudutswa, uye kuvapo kwesipo nemamwe makemikari.

Munzira dzekuchenesa mvura yakasviba, furo rinogona kuvharira michina, kuderedza kushanda zvakanaka kwenzira yekuchenesa, uye kukanganisa kunaka kwemvura yakarapwa. Kuwedzera ma defoamers mumvura kunogona kuderedza kana kudzivirira kuumbwa kwefuro, izvo zvinobatsira kuchengetedza nzira yekuchenesa ichishanda zvakanaka uye kunatsiridza kunaka kwemvura yakarapwa.

Zvinobvisa furo kana kuti zvinodzivirira furo zvinhu zvemakemikari zvinodzora uye, kana zvichidikanwa, kubvisa furo mumvura yakanatswa kuti zvisakanganisa kubuda kwefuro padanho risingadiwe kana kuti rakawandisa.

Ma defoamers edu anogona kushandiswa munzvimbo dzinotevera:

● Indasitiri yePulp neBepa

● Kurapa nemvura

● Indasitiri yekuchenesa

● Indasitiri yekupenda nekuputira

● Indasitiri yemafuta

● Uye mamwe maindasitiri
