Diethanolamine (DEA) siv
- Surfactants: DEA yog cov khoom siv tseem ceeb rau kev tsim cov khoom tsis yog -ionic surfactants, dav siv hauvtshuaj ntxuav tes, tshuaj zawv plaub hau, da dej gels thiab tshuaj pleev ib ce los muab emulsifying, thickening thiab stabilizing zog.
- Kev Kho Roj: Hauv kev lag luam roj av thiab kev lag luam roj, DEA ua haujlwm ua tus neeg sawv cev desulphurisation, tshem tawm cov roj acidic xws li H₂S thiab CO₂ los ntawm amine scrubbing txheej txheem los txhim kho roj purity.
- Muaj additives: Nws ua hauj lwm raws li ib tug corrosion inhibitor los tiv thaiv cov khoom siv hlau los yog emulsifier hauv lubricants thiab txiav kua. Hauv kev lag luam textile, nws yooj yim rau dye dispersion, thaum nyob rau hauv cov tshuaj tua kab nws ua hauj lwm raws li ib tug intermediate compound.
- Chemical synthesis: DEA yog ua hauj lwm los ua ib qho catalyst nyob rau hauv polyurethane ua npuas ncauj ntau lawm thiab ua ib tug precursor nyob rau hauv tshuaj thiab dye synthesis.
Ntim & Xa
- Ntim: Hlau nruas, IBC Drums, Flexitank, ISO TANK thiab hnab thiab lwm yam.
- Lub sij hawm xa tuaj: 7-10 hnub tom qab tau txais kev pom zoo.
- Shipping Method: Los ntawm hiav txwv, huab cua, los yog courier (FedEx, DHL, UPS, TNT).
