Npuas nyob rau hauv cov dej kho teeb meem ntau tus neeg, debug thaum ntxov npuas, npuas nto active neeg sawv cev, npuas, npuas, peroxide circulating dej kev kho mob ntawm cic thiab tsis oxidizing bactericide ua npuas ncauj, thiab lwm yam., yog li cov dej kho yog ib qho ntawm feem ntau siv. ntawm kev tshem tawm npuas tus neeg sawv cev, daim ntawv no qhia txog lub hauv paus ntsiab lus ntawm defoaming tus neeg saib xyuas, kev faib tawm, kev xaiv thiab kev siv.
Foam tshem tawm txoj kev
1. Kev siv lub cev
Xav txog physics tshem tawm txoj kev ua npuas ncauj feem ntau suav nrog tso baffle lossis mesh, mechanical stirring, electrostatic, refrigeration, heating, steam generating, radiation, high speed centrifugal, pressure relief, high zaus vibration, instantaneous discharge thiab ultrasonic acoustic kua (tswj) , thiab lwm yam, ntawm cov txheej txheem no nyob rau hauv ntau qhov kev txhawb nqa los ntawm tus nqi thiab cov kua membrane ntawm ob qhov kawg ntawm cov pa roj npuas zaj duab xis ntawm cov kua dej, Cov stabilizing yam ntawm npuas yog tsawg tshaj li qhov decaying yam, thiab cov npuas maj mam txo.Tab sis qhov tsis zoo ntawm cov txheej txheem no yog qhov kev siv ntawm ib puag ncig yam txwv tsis pub, defoaming tus nqi tsis siab, qhov zoo nyob hauv kev tiv thaiv ib puag ncig, siab rov siv dua.
2. Cov txheej txheem tshuaj
Cov txheej txheem ntawm kev tshem tawm cov foams los ntawm cov tshuaj lom neeg pom feem ntau suav nrog cov tshuaj tiv thaiv tshuaj thiab ntxiv defoamer.
Cov tshuaj tiv thaiv kab mob yog hais txog cov tshuaj tiv thaiv ntawm qee cov tshuaj reagents thiab foaming tus neeg sawv cev los tsim cov tshuaj insoluble, yog li txo cov concentration ntawm surfactant hauv cov kua zaj duab xis thiab txhawb kev tawg ntawm npuas.Txawm li cas los xij, txoj kev no muaj qhov tsis zoo xws li tsis paub tseeb foaming tus neeg sawv cev muaj pes tsawg leeg thiab cov khoom tsis zoo rau cov khoom siv hauv lub cev.Tam sim no txoj kev siv defoaming ntau tshaj plaws nyob rau hauv txhua qhov chaw ntawm lub neej yog txoj kev ntxiv defoaming tus neeg sawv cev.Qhov txiaj ntsig loj tshaj plaws ntawm txoj kev no yog tias nws ua haujlwm tau zoo thiab siv tau yooj yim, tab sis nrhiav kev tsim nyog thiab muaj txiaj ntsig defoaming tus neeg sawv cev yog tus yuam sij.
Txoj cai ntawm defoamer
Defoaming tus neeg saib xyuas, tseem hu ua defoaming tus neeg saib xyuas, muaj cov hauv qab no:
1. Lub hauv paus nto nro ntawm cov npuas dej yog txo, uas ua rau bursting ntawm npuas
Lub tshuab pib thaum muaj cawv ntau dua lossis cov roj zaub siv rau hauv cov npuas dej, uas, thaum yaj hauv cov npuas dej, txo qhov nro ntawm qhov chaw ntawd.Vim tias cov tshuaj no feem ntau tsis tshua muaj dej, qhov txo qis hauv qhov nro yog txwv rau thaj tsam ntawm cov npuas dej, thaum qhov nro ntawm cov npuas npuas tsis tshua hloov.Ib feem ntawm qhov txo qhov nro yog rub tawm hauv txhua qhov kev qhia, txuas ntxiv, thiab thaum kawg ruptured.
2, rhuav tshem zaj duab xis elasticity thiab ua rau npuas tawg
Thaum defoaming tus neeg sawv cev ntxiv rau hauv lub tshuab ua npuas ncauj, nws yuav diffuse rau cov roj-kua interface, ua rau nws nyuaj rau cov surfactant nrog npuas stabilizing muaj nuj nqi kom rov qab elasticity ntawm zaj duab xis.
3, txhawb nqa cov yeeb yaj kiab ua kua
Defoaming tus neeg saib xyuas tuaj yeem txhawb nqa cov yeeb yaj kiab ua kua, ua rau npuas tawg, tus nqi ntawm cov npuas dej tuaj yeem cuam tshuam qhov ruaj khov ntawm cov npuas dej, ntxiv cov khoom siv kom nrawm ua npuas dej, tuaj yeem ua lub luag haujlwm ntawm defoaming.
4, ntxiv cov khoom hydrophobic tuaj yeem ua rau npuas tawg
Hydrophobic cov khoom nyob rau saum npoo ntawm npuas yuav nyiam cov hydrophobic kawg ntawm surfactants, yog li cov khoom siv hydrophobic tsim hydrophilicity thiab nkag mus rau theem dej, thiaj li ua lub luag haujlwm ntawm defoaming.
5, solubilizing ua npuas ncauj surfactant tuaj yeem ua rau npuas tawg
Qee cov tshuaj tsis tshua muaj molecular uas sib tov zoo nrog cov tshuaj tuaj yeem solubilize cov bubbling surfactant thiab txo nws cov concentration zoo.Cov tshuaj tsis tshua muaj molecular nrog cov nyhuv no, xws li octanol, ethanol, propanol thiab lwm yam cawv, tuaj yeem tsis tsuas yog txo cov surfactant concentration ntawm txheej txheej, tab sis kuj yaj mus rau hauv cov surfactant adsorption txheej, txo qhov nruj ntawm cov surfactant molecules, yog li tsis muaj zog. stability ntawm lub npuas.
6. Electrolyte dissolves ob txheej ntawm surfactant
Rau cov surfactant nrog kev pab los ntawm ua npuas ncauj ob chav hluav taws xob txheej kev sib cuam tshuam, kev ruaj ntseg ntawm foaming kua, ntxiv cov electrolyte zoo tib yam tuaj yeem zom cov surfactant ob txheej hluav taws xob los ua lub luag haujlwm hauv defoaming.
