MoDTC flash point ≥180°C is 30°C higher than MoDTP (≥150°C) - a direct consequence of the DTC ligand's higher molecular weight and lower vapour pressure vs the DTP ligand. Higher FP means: safer storage and handling (further from flammable liquid territory); better retention in high-temperature engine sumps (>150℃siab); qis volatility poob hauv kev pabcuam. Qhov no yog qhov muaj txiaj ntsig zoo rau qhov ntev -drain PCMO formulations qhov twg additive retention ntawm qhov kawg ntawm cov dej ncua sij hawm.

Daim Ntawv Thov & Kev Qhia Txog Kev Siv Tshuaj
1. ACEA C1/C5 & ILSAC GF-6B - Cov Ntaub Ntawv Siv Tseem Ceeb
MoDTC yog tustsuas yog organomolybdenum kev sib txhuam hloov kev xaiv rau ACEA C1 (P Tsawg dua lossis sib npaug li 0.05%), ACEA C5, thiab ILSAC GF-6B ultra-low-P lubricants. Nyob rau hauv tus qauv ACEA C1 cav roj formulation: ZDDP ntawm 0.35–0.45 wt% contributes ~ 0.035–0.045% P - twb nyob rau los yog ze li ntawm 0.05% txwv. Ntxiv MoDTC ntawm 0.05–0.15 wt% ua rau 0 ntxiv P, xa tag nrho MoS₂ FM kev ua tau zoo (+1.5–2.5% FEI hauv Sequence VIE) hauv P txwv. Cov ntsiab lus N (2.5–3.5%) los ntawm MoDTC decomposition byproducts (dialkylamines) yog sib xws nrog ACEA C1 specifications - N tsis yog SAPS keeb thiab tsis cuam tshuam rau cov kev txwv tshwj xeeb. Rau hybrid thiab plug{20}}hauv hybrid electric tsheb (HEV/PHEV) cav roj - ib daim ntawv thov loj hlob sai qhov twg ACEA C1/C5 specifications predominate - MoDTC yog kev lag luam-tus qauv organomolybdenum FM. Toyota, Honda, thiab European OEMs qhia txog roj- qib roj kev lag luam thoob ntiaj teb lees paub MoDTC raws li FM tsim nyog rau qis -SAPS cov lus qhia tshwj xeeb.
2. PCMO & HDEO Cav Roj - Kev siv roj ntau dua
Beyond ACEA C1, MoDTC is also used across ACEA C2/C3/C5 and API SP/SN+ PCMO formulations where the formulator wants to keep the P budget entirely reserved for ZDDP without splitting it with MoDTP. At 0.05–0.15 wt% MoDTC in 0W-20/0W-30 PCMO, combined with the three-component AO stack (NDPA 0.2–0.3 wt% + L01-type 0.3–0.4 wt% + ZDDP 0.6–0.8 wt%), the complete API SP formulation achieves: ASTM Sequence VIE FEI ≥1.5%; Sequence IIIGH oxidation control; Sequence IVB cam wear (low-P valve-train protection). For HDEO ACEA E6/E9 (low-SAPS diesel), MoDTC at 0.1–0.2 wt% adds FM benefit to long-drain diesel engine oils without any impact on the closely managed P budget - extended-drain HDEO formulations benefit particularly from MoDTC's higher FP (≥180°C vs MoDTP's ≥150°C) ensuring better additive persistence at HDEO operating temperatures (>150℃sump peaks).
3. Muaj Iav, Hydraulic & Compressor Roj
Hauv kev lag luam iav roj (DIN 51517-3 CLP, AGMA EP qib), cov roj hydraulic (DIN 51524-2/3 HLP), thiab cov roj compressor (DIN 51506 VDL) uas tsis muaj P specification txwv siv, MoDTC raug xaiv dhau MoDTP thaum tus formulator xav tauphosphorus -dawb formulation rau ib puag ncig los yog cov cuab yeej compatibility vim li cas- Piv txwv li, hauv cov zaub mov- qib ib puag ncig ib puag ncig, hauv cov khoom siv nrog phosphate- cov coatings rhiab heev, los yog hauv cov xim dawb- cov ntawv lo muaj roj nplua nyeem ua lag luam li "phosphorus-dawb." Ntawm 0.2–0.5 wt% hauv cov roj iav, MoDTC txo cov iav -mesh ciam teb kev sib txhuam thiab txhim kho FZG- ntsuas iav kis tau tus mob los ntawm 0.5–1.5%. Lus Cim: Yog tsis muaj DTP los tiv thaiv- hnav zaj duab xis ntawm MoDTP, MoDTC ntawm cov nqi kho mob yuav tsum tau ua ke nrog rau AW additives (ZDDP lossis S-P EP additive) kom paub meej tias muaj kev tiv thaiv txaus los tiv thaiv- hnav tiv thaiv - MoDTC muab MoS₂ FM tab sis tsis yog tag nrho AWs tiv thaiv MoDTP zaj duab xis.
4. Cov khoom siv hlau ua haujlwm & cov roj ntsha tshwj xeeb
Hauv cov khoom siv hlau ua haujlwm (MWF) - ob qho tib si roj zoo-raws li (ISO 6743-7 MH qeb) thiab raws li cov roj theem ntawm semi- hluavtaws MWFs - MoDTC ntawm 0.1–0.5 wt% muab FM thiab EP kev ua tau zoo rau kev sib tsoo, kev sib tsoo, kev ua haujlwm drilling. Lub P-dawb ntawm MoDTC yog tshwj xeeb tshaj yog muaj nuj nqis hauv MWF daim ntawv thov uas phosphorus tuaj yeem cuam tshuam nrog qee qhov kev kho saum npoo (phosphate ua ntej{10}} cov txheej txheem kho rau tsheb stampings) lossis raug txwv los ntawm cov khoom siv tshwj xeeb (titanium thiab npib tsib xee alloys machined rau aerospace} feem ntau tiv thaiv kev xeb rau{12}). MoDTC's DTC- muab tau los ntawm amine byproducts (dialkylamines) kuj muab cov tshuaj tiv thaiv me me rau ntawm cov hlau tsis tu ncua tshiab - cov txiaj ntsig thib ob uas MoDTP's phosphate byproducts tsis muaj kev huv. Rau biostable MWF formulations (ntev-lub neej semi-synthetic), MoDTC kev sib raug zoo nrog emulsifiers, xeb inhibitors, thiab biocide systems raug txheeb xyuas ntawm cov nqi kho mob uas tsis muaj emulsion so lossis kev ua haujlwm degradation.

Cov lus nug nquag
Q: Puas yog MoDTC muab qhov kev sib txhuam zoo ib yam li MoDTP, txawm tias qhov sib txawv ligand?
Yog -Kev sib txhuam txo kev ua haujlwm ntawm MoDTC thiab MoDTP yog qhov ua haujlwm sib npaug ntawm qhov sib npaug Mo cov ntsiab lus kho tus nqi. Hom FM nquag nyob rau hauv ob qho tib si yog MoS₂ - ligand (DTC lossis DTP) tsuas yog lub tsheb xa khoom uas tswj cov khoom siv lub cev thiab SAPS muaj pes tsawg leeg ntawm niam txiv compound. Ntau tus phooj ywg- tshuaj xyuas cov kev tshawb fawb tribology thiab OEM tsim cov kev pabcuam tau lees paub tau lees paub tias MoDTC thiab MoDTP ntawm qhov sib npaug Mo-cov ntsiab lus kho tus nqi xa cov lej sib npaug: MoS₂ tribofilm thickness ( ntsuas los ntawm SIMS qhov tob profile); ciam teb kev sib txhuam coefficient (μ 0.03-0.07 ntsuas ntawm SRV lossis MTM tribometers); kev txhim kho roj kev lag luam hauv ASTM Sequence VIE (FEI 1.5–2.5%); thiab hnav caws pliav txoj kab uas hla hauv ASTM D4172 plaub- kev sim pob thaum ua ke nrog ZDDP. Qhov sib txawv ntawm qhov kev ua tau zoo tsuas yog tias MoDTP tseem muab AW kev koom tes los ntawm DTP phosphate zaj duab xis, uas MoDTC tsis - hauv cov ntawv thov uas ZDDP muab kev tiv thaiv AW txaus, qhov sib txawv no tsis tseem ceeb.
Q: MoDTC muaj N (2.5–3.5%). Qhov no puas cuam tshuam rau SAPS kev ua raws cai lossis ua rau muaj teeb meem kev sib raug zoo?
Nitrogen los ntawm MoDTC uatsis cuam tshuam rau kev ua raws SAPS- SAPS acronym (Sulphated Ash, Phosphorus, Sulphur) tsis suav nrog nitrogen. N hlawv rau N₂ / NOx hauv combustion yam tsis tau tawm ntawm cov hlau seem (xoom tshauv ntawm N), tsis muaj tshuaj lom catalytic converter lossis DPF, thiab tsis tso npe rau hauv ASTM D482 (ash), D4951 (P), lossis D4294 (S) ntsuas. Cov ntsiab lus N yog li tag nrho cov ACEA thiab API SAPS txwv. Hais txog kev sib raug zoo: DTC- muab dialkylamine byproducts tso tawm thaum lub sij hawm MoS₂ tribofilm tsim yog me ntsis nitrogen hauv paus. Ntawm kev kho tus nqi (0.05–0.15 wt% MoDTC hauv cov roj tiav), cov amine concentration tsawg heev (<0.005 wt% in oil) - generally beneficial as a mild copper/lead corrosion inhibitor. However, formulation compatibility should be confirmed for specific DI packages at the proposed treat rate - ASTM D130 copper strip corrosion is the standard screening test; MoDTC at recommended treat rates typically gives D130 1a or 1b rating (acceptable).
Q: Thaum twg kuv yuav tsum xaiv MoDTC tshaj MoDTP, thiab rov ua dua?
Xaiv MoDTCthaum: (1) ACEA C1 lossis ILSAC GF-6B specification (P Tsawg dua lossis sib npaug li 0.05%) - MoDTC yog qhovnkaus xwborganomolybdenum FM xaiv; (2) ACEA C2/C5 (P Tsawg dua lossis sib npaug li 0.07%) thiab tag nrho P pob nyiaj siv twb xav tau rau ZDDP; (3) phosphorus - cov roj nplua nyeem dawb yuav tsum muaj rau ib puag ncig, khoom siv sib xws, lossis kev lag luam vim li cas; (4) FP siab dua (Ntau dua lossis sib npaug rau 180℃vs Ntau dua lossis sib npaug li 150 degree) yog xav tau rau kev khaws cia zoo dua nyob rau hauv siab -kev siv kub.Xaiv MoDTPthaum: (1) ACEA C3 los yog API SP formulations nrog muaj P pob nyiaj (tsawg dua los yog sib npaug rau 0.08% P) - MoDTP muab FM + AW dual muaj nuj nqi, zoo tso cai rau ZDDP kho tus nqi txo thaum tswj AW kev ua tau zoo; (2) kev lag luam iav / hydraulic daim ntawv thov tsis muaj P txwv qhov twg AW pab los ntawm DTP tshwj xeeb xav tau ntxiv ZDDP. Rau kev taw qhia dav dav:ACEA C1/C5/GF-6B → MoDTC; ACEA C3/C2 nrog rau P pob nyiaj siv → ob qho tib si; tsis muaj P txwv / muaj → MoDTP nyiam dual FM + AW muaj nuj nqi. Hu rau Sinolook nrog koj lub hom phiaj tshwj xeeb rau cov lus pom zoo tshwj xeeb thiab SAPS daim ntawv suav.
