Defoamers nyob rau hauv Industrial Applications

Defoamersyog qhov tseem ceeb hauv kev siv tshuab. Ntau cov txheej txheem kev lag luam tsim ua npuas dej, txawm tias nws yog cov neeg kho tshuab agitation lossis tshuaj tiv thaiv. Yog tias nws tsis tswj thiab kho, nws tuaj yeem ua rau muaj teeb meem loj.

Ua npuas ncauj yog tsim vim muaj cov tshuaj surfactant nyob rau hauv cov dej system, uas stabilize cov npuas, uas ua rau ua npuas ncauj tsim. Lub luag haujlwm ntawm defoamers yog los hloov cov tshuaj surfactant, ua rau cov npuas tawg thiab txo cov npuas dej.

Dab tsi yog hom ua npuas ncauj tseem ceeb?

Biofoam thiab surfactant ua npuas ncauj:

Biofoam yog tsim los ntawm cov kab mob thaum lawv metabolize thiab decompose organic teeb meem hauv dej khib nyiab. Biofoam muaj cov npuas me me, ruaj khov heev, thiab zoo li qhuav.

Surfactant ua npuas ncauj yog tshwm sim los ntawm kev sib ntxiv ntawm surfactants xws li xab npum thiab detergents, los yog los ntawm cov tshuaj tiv thaiv corrosives nrog roj los yog roj thiab lwm yam tshuaj.

Defoamers ua haujlwm li cas?

Defoamers tiv thaiv kev tsim ua npuas ncauj los ntawm kev hloov cov khoom ntawm cov kua. Defoamers hloov surfactant molecules nyob rau hauv nyias txheej ntawm ua npuas ncauj, uas txhais tau hais tias lub monolayer tsis tshua muaj elasticity thiab feem ntau yuav tawg.

Yuav xaiv tus defoamer li cas?

Defoamers feem ntau muab faib ua silicone-based defoamers thiab non-silicone-based defoamers. Kev xaiv ntawm defoamer nyob ntawm qhov yuav tsum tau ua thiab cov xwm txheej ntawm daim ntawv thov tshwj xeeb. Silicone-based defoamers muaj txiaj ntsig zoo nyob rau hauv ntau yam ntawm pH thiab qhov kub thiab txias thiab feem ntau nyiam rau lawv cov kev ruaj ntseg thiab kev ua haujlwm. Non-silicone-raws li defoamers yog defoamers raws li cov organic tebchaw xws li fatty amides, hlau soaps, fatty alcohols, thiab fatty acid esters. Qhov zoo ntawm cov tshuab uas tsis yog-silicone yog loj diffusion coefficients thiab muaj zog ua npuas ncauj tawg muaj peev xwm; Qhov tsis zoo tseem ceeb yog qhov ua npuas ncauj muaj peev xwm ua kom tsis zoo me ntsis vim qhov siab dua qhov nro dua li silicone.

Thaum xaiv qhov zoo defoamer, yam xws li hom kab ke, kev ua haujlwm (kub, pH, siab), tshuaj lom neeg sib raug zoo, thiab kev tswj hwm yuav tsum tau xav txog. Los ntawm kev xaiv txoj cai defoamer, kev lag luam tuaj yeem tswj cov teeb meem cuam tshuam nrog ua npuas ncauj thiab txhim kho cov txheej txheem tag nrho.

Thaum twg defoaming additive xav tau hauv kev kho dej?

Thaum lub sij hawm kho dej, feem ntau muaj tej yam kev mob uas tsim nyog rau foaming, xws li agitation ntawm dej, tso tawm ntawm yaj gases, thiab muaj detergents thiab lwm yam tshuaj.

Hauv cov txheej txheem kho dej khib nyiab, ua npuas dej tuaj yeem txhaws cov cuab yeej, txo cov txheej txheem kho, thiab cuam tshuam rau qhov zoo ntawm cov dej kho. Ntxiv cov defoamers rau dej tuaj yeem txo lossis tiv thaiv kev tsim cov npuas dej, uas pab ua kom cov txheej txheem kho kom zoo thiab txhim kho cov dej kho kom zoo.

Defoamers lossis antifoam agents yog cov khoom siv tshuaj uas tswj tau thiab, yog tias tsim nyog, tshem cov npuas dej los ntawm kev kho dej kom tsis txhob muaj qhov tsis zoo ntawm foaming ntawm cov theem tsis zoo lossis ntau dhau.

Peb cov defoamers tuaj yeem siv rau hauv cov chaw hauv qab no:

● Pulp thiab ntawv kev lag luam

● Kev kho dej

● Kev lag luam detergent

● Xim thiab Txheej kev lag luam

● Oilfield kev lag luam

● Thiab lwm yam kev lag luam
