Ua npuas ncauj hauvtxheej txheej, qhov tseem ceeb ntawm huab cua raug kaw los ntawm cov yeeb yaj kiab ua kua ruaj khov, tuaj yeem tswj tau los ntawm kev sib xyaw ua ke, kev tswj cov txheej txheem, thiab cov txheej txheem siv.
1. Formulation: Lub Defoamer System
Qhov no yog kauj ruam tseem ceeb tshaj plaws. Kev sib xyaw ua kom zoo defoamers thiab huab cua- tso tawm yog qhov tseem ceeb.
Xaiv: Xaiv cov defoamers raws li koj qhov system:
Mineral Roj-raws li: Tus nqi- zoo rau cov qauv emulsions.
Pom zoo (BASF)--Foamaster® 111, (Evonik)--TEGO® Foamex 810, (Elements PLC)--Burst® 100 / Burst® 200
Silicone-raws li: Ua tau zoo, siv tsawg, ntau yam.
Pom zoo (Evonik)--TEGO®Foamex 810 / 822 / 825, (BASF)--FoamStar® ST 24, (Alnex) - Additol®VXW 4973
Silicone-Dawb Polymers: Kev sib raug zoo heev, zoo tagnrho rau cov tsho loj thiab siab -gloss tiav qhov chaw muaj qhov tsis xws luag.
Pom zoo (EvonikTEGO® Airex, (BASF)--Foamaster® 3407, (Alnex) --Additol® VXW 4940
Ntxiv Strategy: Ntxiv defoamers hauv ob theem:
Thaum sib tsoo: Ntxiv ua ntej siab - nrawm nrawm los tiv thaiv kev ua npuas dej los ntawm cov hmoov sib xyaw.
Thaum lub sij hawm cia-Down: Ntxiv tom qab emulsions sib xyaw kom tshem tawm cov cua nkag los ntawm kev sib tov tom qab.
2. Cov txheej txheem ntau lawm: txo qis cua nkag
Txhim kho kev tsim khoom kom tsis txhob ua npuas ncauj.
Kev sib xyaw: Tsis txhob muaj kev ntxhov siab ntau dhau thiab siab -kev sib xyaw "qhuav" ceev. Siv cov dispersing discs es tsis txhob ntawm cov kiv cua, thiab xyuas kom lawv nyob twj ywm submerged.
Kev tuav cov khoom siv: Tswj tus nqi ntws thaum siv cov kua dej kom txo tau qhov kub thiab txias sib xyaw.
3. Daim Ntawv Thov: Kev Tiv Thaiv Kawg
Cov txheej txheem tsim nyog tiv thaiv kev tsim ua npuas dej ntawm lub substrate.
Cov cuab yeej: Siv siab- zoo, nruab nrab- nap rollers; pheej yig feem ntau entrap ntau cua.
Cov txheej txheem: Siv nrog "slow-nce, nrawm- nqis" dov cov lus kom nteg tawm cov txheej txheem kom du. Tsis txhob dhau - ua haujlwm tib thaj chaw, tshwj xeeb tshaj yog thaum zaj duab xis pib teeb.
Cov xwm txheej: Tsis txhob siv rau qhov chaw kub, vim tias qhov ziab sai sai tuaj yeem tso pa tawm, ua rau micro- npuas thiab pinholes.
Hauv cov ntsiab lus, xaiv thiab theem defoamers kom raug hauv kev tsim, tswj cov txheej txheem sib xyaw kom nruj, thiab tswj cov txheej txheem thov kom raug. Qhov kev sib xyaw ua ke no ua rau txo qis ua npuas ncauj los ntawm kev tsim khoom mus rau qhov kawg zaj duab xis.
