Low Viscosity Dispersant yog dab tsi?
Tsawg viscosity Dispersant(Low Molecular Bis-Succinimide) hais txog cov txheej txheem tseem ceeb ntawm kev siv succinimide dispersants nyob rau hauv niaj hnub qis - viscosity cav roj: viscosity contribution ntawm dispersant nws tus kheej. Raws li OEM specifications tau ua tiav cov cav roj viscosity qib nce qis dua - los ntawm SAE 10W-40 (ib txwm HDEO hauv xyoo 2000s) → 5W-30 (GF-4 era) → 0W-20 (GF-5 / API SN era) → 0W-16 / 20ILAC-6 tshwm sim 0W-8 - lub qhov rais kinematic viscosity ntawm cov roj tiav tau nqaim los ntawm Ntau dua lossis sib npaug ntawm 12 cSt rau 5.6–7.1 cSt @ 100℃(rau 0W-16).

Cov lus nug nquag
Q: Puas yog Low Viscosity Dispersant tsuas yog diluted bis -succinimide (cov roj diluent ntxiv ntxiv kom txo cov viscosity)?
Tsis yog - qhov no yog qhov sib txawv tseem ceeb. Tsawg Viscosity Dispersant ua tiav nws cov viscosity qis dua los ntawm kev siv lub hauv paus qis dua -MW PIB qaum (~ 400–600 MW vs ~ 900–1300 rau cov qauv bis), tsis yog los ntawm kev ntxiv roj ntxiv. Ntxiv cov roj diluent rau tus qauv bis-succinimide txo cov dispersant N% cov ntsiab lus proportionally thaum lub polymer chains lawv tus kheej nyob siab -MW (thiab yog li siab -intrinsic-} viscosity) - yuav tsum tau ntau dua diluent theem kom ua tiav cov khoom qis heev thiab viscosity siab. cov ntsiab lus uas yog ib qho tseem ceeb diluted standard{13}}qib khoom. Los ntawm qhov sib txawv, Low Viscosity Dispersant qhov viscosity tsawg yog los ntawm cov polymer tus kheej cov viscosity qis dua (qis -MW chains) - yog li cov N% tseem txaus (1.0-2.5%) ntawm cov khoom lag luam ib txwm diluent cov ntsiab lus. Ob yam khoom - diluted standard-qib vs lub hom phiaj-synthesised qis-MW qib - muaj tib yam khoom viscosity tab sis txawv heev polymer architecture, N% ib chav tsev qhov hnyav, thiab cov yam ntxwv ntawm kev ua tau zoo ntawm qhov sib npaug ntawm cov roj tiav lawm.
Q: Puas yog qhov luv luv PIB tus Tsov tus tw ua rau txo qis kev ua haujlwm sib txawv vs tus qauv Bis-Succinimide?
At moderate soot concentrations (≤3 wt%), the difference in dispersancy is small and practically insignificant. The polar head group architecture (bis-succinimide + free –NH₂) is preserved in the low-MW grade - the adsorption affinity of the succinimide heads for soot particle surfaces is unchanged. The PIB tail's role is primarily steric stabilisation (creating a physical barrier between suspended soot particles to prevent agglomeration) - and shorter PIB tails provide a proportionally smaller steric exclusion zone. At high soot concentrations (>4–5 wt%, as in severe EGR HDEO applications), this smaller steric zone means earlier soot particle flocculation onset - requiring slightly higher treat rates (6–8 wt% vs 4–6 wt% for standard bis) or blending with higher-MW bis-succinimide to compensate. For PCMO (typical soot concentration 0.5–2 wt%), this limitation is largely irrelevant - Low Viscosity Dispersant performs equivalently to standard bis-succinimide at matched N% delivery. The grade selection guidance is straightforward: primary application constraint is viscosity (0W grades, cold blending, hydraulic/compressor) → choose Low Viscosity Dispersant; primary performance constraint is high-soot capacity (severe EGR HDEO >4% soot) → xaiv tus qauv lossis Poly-Succinimide.
Q: Tsawg Viscosity Dispersant piv rau Poly-Succinimide li cas rau cov roj viscosity qis?
Qhov no yog ib qho kev sib piv tsis nkag siab ntau zaus. Poly-succinimide feem ntau pom zoo rau qis- cov roj viscosity vim nws siab N% (2.0–6.0%) txhais tau hais tias tib qho kev sib cais tuaj yeem ua tiav ntawm tus nqi kho mob qis dua - thiab yog li txo qis viscosity. Ntawm N 4.0%, poly-succinimide ntawm 2.5 wt% xa tib N li Low Viscosity Dispersant ntawm ~ 6 wt%; poly-succinimide's viscosity contribution ntawm 2.5 wt% kho yog kwv yees li +1.5-2.5 cSt vs Low Viscosity Dispersant's +4 cSt ntawm 6 wt% kho - nyiam poly-succinimide me ntsis ntawm pob nyiaj siv. Txawm li cas los xij, Low Viscosity Dispersant muaj ntau qhov zoo tshaj plaws ntawm poly-succinimide hauv ntau 0W- qib kev tsim cov xwm txheej: (1) tus nqi qis dua ib kg; (2) tuav tau yooj yim dua (100–250 cSt vs 200–1000 cSt rau poly); (3) txias zoo dua- huab cua blendability; (4) kev kwv yees ntau dua viscosity pab tau (ntxhiab ntau); (5) Sequence VH sludge kev ua tau zoo (dawb -NH₂ pawg davhlau ya nyob twg, zoo ib yam li mono-PIBSI). Qhov kev xaiv zoo tshaj plaws yog nyob ntawm qhov kev tsim tshwj xeeb N qhov yuav tsum tau muaj, pob nyiaj siv viscosity, thiab kev sib xyaw cog kev txwv. Nyob rau hauv kev xyaum, ib tug peb -cov khoom dispersant sib tov (Low Viscosity Dispersant + standard Bis + trace Borated Bis rau TBN) feem ntau muab qhov zoo tshaj plaws ua ke ntawm viscosity tswj, dispersancy, thiab nqi rau premium 0W-20 PCMO formulations.
