Performance Profile - Tsib Simultaneous Functions
① Soot/Sludge Dispersancy (Bis Backbone)
The bis-succinimide backbone provides dual-PIB steric stabilisation of soot particles in the bulk oil phase - same mechanism as non-borated bis-succinimide. Dispersancy performance confirmed by ASTM D7843 blotter spot test and Sequence VH sludge rating. The N% (1.5–3.0%) maintains adequate polar adsorption site density for soot encapsulation despite partial conversion of –NH groups to B and P ester linkages. In extreme soot-loading conditions (Mack T-13 test, soot >4 wt%), dual-PIB bis architecture muab superior viscosity tswj vs mono-succinimide qib.

Q: Puas yog phosphate ester linkage nyob rau qib no rhiab heev rau hydrolysis, thiab nws cov dej noo ruaj khov piv rau borate ester li cas?
Phosphate esters (P-O-C bonds) feem ntau yog hydrolytically ruaj khov dua li borate esters (B-O-C bonds) nyob rau hauv tib yam kev mob - phosphorus cov ntaub ntawv muaj zog P-O-C bonds (daim ntawv cog lus dissociation zog ~ 360 kJ / mol) piv rau cov B-O-C daim ntawv cog lus (J3) pawg (~ 3) mol (~ 3) Lewis acid tsis zoo dua li qhov chaw boron, ua rau nws tsis tshua muaj kev cuam tshuam rau nucleophilic nres los ntawm cov dej molecules. Hauv kev xyaum: (1) Cov phosphate ester nyob rau hauv qib no tsis tas yuav tsum muaj tib yam kev txwv tsis pub ya raws nruj raws li cov qib borated - tus qauv kaw cia (tsawg dua lossis sib npaug ntawm 0.15% dej los ntawm KFT) txaus; (2) Nyob rau hauv cov roj tiav ntawm qhov kub crankcase, phosphate ester hydrolysis yog negligible tshaj 15,000 km ntws lub caij; (3) Cov borate ester pawg hauv tib lub molecule yog cov dej noo ntau dua -sensitive dua li cov phosphate ester pawg - KFT Tsawg dua lossis sib npaug li 0.15% dej txwv feem ntau siv los tiv thaiv borate ester tivthaiv. Qib- cov ntaub ntawv tshwj xeeb ntawm cov dej rhiab heev yog muaj nyob rau ntawm SDS thiab TDS muab rau txhua qhov khoom xa tuaj.
