Peb tiam neeg dag yog ib qho silicone defoamer raws li polydimethylsiloxane (PDMS, Dosethyl Silicone Roj). Tam sim no, kev tshawb fawb thiab kev thov ntawm cov cim no ntawm defoamers tau cov feem ntau muaj nyob hauv Suav teb. PDMs yog tsim los ntawm silicon cov saw hlau thiab lwm pawg organic, thiab tsis tuaj yeem tau npaj kom nruj ntawm cov npuas dej ua kua, kom cov npuas yuav tawg ntho. LO viscosity pdms muaj cov cuab yeej defoaming zoo thiab siab viscosity pdms muaj cov cuab yeej defoaming zoo.
Qhov Zoo Ntawm Silicone defosamer
Nws muaj cov tshuaj lom neeg hauv cov tshuaj orsia thiab yog qhov nyuaj rau kev hnov mob nrog lwm cov tshuaj. Nws tuaj yeem siv tau rau hauv acid, alkali thiab ntsev daws.
Zoo lub cev hauv kev ua haujlwm, tuaj yeem siv hauv cov khoom noj thiab cov tshuaj lag luam, thiab tsis muaj kuab paug rau ib puag ncig.
Nws muaj cov zoo thermal ruaj khov thiab tsis muaj zog qis, thiab tuaj yeem siv hauv qhov ntsuas kub ntau.
Lub viscosity yog tsawg thiab kis tau sai ntawm cov roj-kua interface.
Sab nro qis li 1.5-20 mn / m (76 mn / m rau dej).
Nws tsis yooj yim los ua solubilized los ntawm surfactant hauv cov foaming system.
Tsawg ntau ntau tshuaj, qis viscosity thiab cov nplaim roj tsawg.
Qhov tsis zoo ntawm Silicone defoamer
1. Nws yog qhov nyuaj rau kev tawg hauv cov dej hauv dej.
2. Vim tias nws yog soluble nyob rau hauv cov roj, defoaming nyhuv nyob rau hauv cov roj system yog txo.
3. Cov siab tsis zoo.
4. Tsis kam mus rau muaj zog alkalinity.
Tus nqi siab:PDMS yog dej hauv cov roj (O / W) emulsion ua los ntawm Silicone roj, emulsifier, thickener, thiab lwm yam, uas yog emulsified los ntawm dej. Cov kev nro saum npoo kom sai thiab muaj zog tiv thaiv ua npuas ncauj thiab tiv thaiv kev ua npuas ncauj. Nws yog kwv yees muab faib ua peb daim qauv: Silicone roj, Silicone ROJ + hloov kho polyether thiab polyether hloov silicone roj.
Nws yog tus cwj pwm los ntawm:Tsawg Degic nro, cov dej num siab thiab muaj zog defoaming zog.
Tsawg npaum li cas noj:Nws tuaj yeem tiv thaiv thiab tawg npuas rau feem ntau yog cov me nyuam npuas ntau.Nws muaj cov zoo thermal ruaj khov thiab tuaj yeem siv rau hauv qhov ntsuas kub ntau.Nws tau koom nrog polyether thiab muaj syergistic nyhuv.Nws yog dav siv rau defoaming nyob rau hauv xab npum, pulrermaking, qab zib ua, hluav taws xob chiv, ntxiv tshuaj ntxiv thiab lwm yam txheej txheem ntau lawm. Nyob rau hauv kev lag luam roj av, nws yog dav siv rau desulfurization ntawm cov nkev nce nrawm roj-roj sib cais; Nws kuj tseem siv los tswj lossis kev tswj hwm bubbles hauv cov khoom siv xws li ethylene glycoling, asphalt ua thiab lubricating roj dewaxing. Hauv kev lag luam textile, nws yog siv rau defoaming nyob rau hauv dyeing, scouring, sizing thiab lwm yam txheej txheem; Nws yog siv nyob rau hauv cov txheej txheem emulsion thiab defoaming hauv kev lag luam; Nws yog siv rau defojing nyob rau hauv ntau lub siab, fermentation thiab cov txheej txheem distillation hauv kev lag luam khoom noj khoom haus.
