Defoamer

Vim li cas cov defoamers xav tau hauv cov dej txo qis?

Vim yog cov qauv molecular ntawm PCE, nws nyiam ua kom paub ntau dhau ntawm cov npuas tsis sib xws thaum sib xyaw. Yog tias tsis muaj kev tswj xyuas, cov npuas no tuaj yeem ua rau ob qho teeb meem loj: ua ntej, lawv cuam tshuam qhov zoo ntawm cov pob zeb, thiab qhov tseem ceeb tshaj, lawv txo cov pob zeb ua kom ntev - lub zog thiab kav ntev.

Hom thiab yam ntxwv tseem ceeb ntawm defoamers

Cov defoamers feem ntau siv hauv PCE-raws li dej reducers poob rau hauv pawg hauv qab no:

Silicone-raws li defoamers:Cov no muaj kev ceev heev defoaming thiab yog dav siv. Lawv kuj yog ib qho ntawm feem ntau tshawb fawb thiab siv hom.

Polyether-raws li defoamers:Hloov kho polyether defoamers muab ua npuas ncauj ntev dua - lub sijhawm tiv thaiv thiab feem ntau pom muaj kev sib raug zoo nrog PCE dua li cov khoom siv silicone -raws li kev xaiv.

Mineral roj-raws li defoamers:Qhov no yog hom tshuaj ntau dua, tab sis nws tsis tshua siv niaj hnub no, vim tias nws cov txiaj ntsig thiab kev ruaj ntseg feem ntau qis dua ob pawg dhau los.

Daim ntawv thov:

Precise ntau npaum:Ntau tsis tas yuav zoo dua. Kev tshawb fawb qhia tau hais tias ua kom cov defoamer ntau npaum li cas los ntawm 0.01% - 0.02% mus rau 0.04% ntawm tag nrho cov huab hwm coj hloov nws lub luag hauj lwm tseem ceeb ntawm huab cua-entraining tus neeg saib xyuas mus rau ib tug defoaming tus neeg saib xyuas, ua rau ib tug ntse poob rau hauv cov huab cua ntsiab lus. Qhov pom zoo pib noj ntau npaum li cas0.05%–0.2%ntawm tag nrho cov huab hwm coj. Overdosing tuaj yeem ua rau los ntshav thiab ua haujlwm tsis zoo ntawm cov pob zeb.

"Defoam ua ntej, ces entrain" txheej txheem:Qhov no yog ib txoj kev paub dav dav thiab siv tau zoo. Lub defoamer tau ntxiv ua ntej txhawm rau tshem tawm cov npuas loj tsis sib xws thaum sib xyaw, ua raws li qhov sib ntxiv ntawm huab cua -entraining tus neeg sawv cev los ua kom paub zoo thiab ruaj khov micro- npuas. Txoj hauv kev no ua kom ob qho tib si pob zeb zoo fluidity (ua haujlwm tau zoo) thiab txhim kho lub zog los ntawm cov qauv pore optimized.

Kev sib xyaw thiab kev khaws cia:Vim muaj teeb meem compatibility, lub defoamer yuav ntab mus rau saum npoo thaum lub sij hawm cia ntawm cov compounded water reducer. Nws raug nquahu kom do tsis tu ncua lossis sib tov kom huv si ua ntej siv. Tsis tas li ntawd, nws yog qhov zoo tshaj plaws los ua haujlwm ntawm apH qis dua 10, raws li ntau dhau alkalinity tuaj yeem cuam tshuam kev ua haujlwm.

Raws li ib qho ntawm cov kws tshaj lij defoamer tuam ntxhab thiab cov muag khoom hauv Suav teb, peb tau tshwj xeeb los ntawm cov khoom zoo thiab tus nqi zoo. Thov so assured mus yuav defoamer ua nyob rau hauv Suav teb nov los ntawm peb lub hoobkas.
