Further panels break down sliding behavior on lubricated textured surfaces, three-dimensional pillar geometries, contact angle hysteresis under external forces, and droplet propulsion inside a tapered capillary tube.

https://oil-glup.ru/threads/natjazhenie-smachivanie-astm-d971-i-ne-tolko.189/#post-5079 Three schematic diagrams contrast different wetting behaviors of a liquid droplet on a rough solid surface in contact with air. Diagram a illustrates the Wenzel state where the liquid fully penetrates the microgrooves of the solid. Diagram b shows the Cassie-Baxter state with the droplet resting on top of the surface structures while trapping air pockets underneath. Diagram c depicts the wet Cassie state where the liquid sits atop the solid features but partially fills the lower grooves.

Next to him, an anthropomorphic green jerrycan with wide, googly eyes and thin legs scratches its spout with a hand-like appendage while carrying a small wheel on the other side. A rustic wooden barn sits in the foggy background beneath barren trees, and utility poles stretch along the damp roadside under a gray, overcast sky.

Each phrase corresponds to a colored horizontal distribution showing median values, interquartile ranges, and individual data points scattered across the grid. Looking at the data, it is what it is, showing that people actually agree pretty well on extreme probabilities while grouping around fifty percent for ambiguous terms.

Base oil shows a van der Waals value of 17.013, an electrostatic value of 0.874, and a total of 17.407. Sulfonate and Ca2+ display a low van der Waals contribution of 10.436 alongside a high electrostatic parameter of 49.213, summing to a total solubility parameter of 50.445. Sulfonate detergent records values of 18.991 for van der Waals and 23.442 for electrostatic, resulting in a total parameter of 30.439.

This test finds the temperature where equal parts aniline and base oil become miscible, serving as a handy gauge for solvent power toward VI improvers, detergents, and anti-wear agents. High saturates oils show high aniline points, whereas naphthenic oils drop much lower, meaning you can fix additive drop-out by blending in a polar synthetic basestock like polyolester.

The accompanying text explains that these degraded one-hour ring zone samples show varying phase separation across different lubricant formulations, while analysis of the separated solid phase points directly to polymer from the viscosity index improver.

Most data points cluster tightly below one gram of wear across various viscosity levels, except for a single outlying point near 5.5 grams at lower viscosity.

https://oil-glup.ru/threads/motornye-masla-exline.187/page-2#post-5055 An Exxon Mobil Corporation monthly report document lists operational receipts from various industrial locations and partners. The table maps incoming sources like MOBIL location LA and TX, EM Chemical Co Baytown Chem Plant, and Infineum USA LP against corresponding RRC numbers.

https://oil-glup.ru/threads/motornye-masla-exline.187/page-2#post-5055 The document lists Exxon Mobil Corporation as the operator alongside a tabulated log of incoming shipments from various industrial chemical companies. Air Products & Chemicals and ExxonMobil Chemical are tagged with CHEM and code 23, while Eurenco, ExxonMobil Oil Corp, Honeywell, and Infineum USA are marked WR with corresponding index numbers. Everything is pretty straightforward once you look at the columns.

https://oil-glup.ru/threads/fedor-gudok-ivanov-bloger-po-prostomu-ili-good54.158/page-7#post-5048 A forum post dated 24.03.2023 at 08:40 shows a user named Good54 from Novosibirsk with 24766 messages responding to a quote from k.v.v asking where to go. The main reply reads Hello write phone to zeropsf@yandex.ru and I will call back. It is what it is when oil forum discussions pivot abruptly to private emails.

https://oil-glup.ru/threads/saen-schugo-who-is-mr-sae20.207/page-2#post-5046 A forum discussion shows a user named SAE20 replying to a question about reverse engineering in motor oils with a casual shrug, deflecting certainty to Igor from Rostov and the folks at ato24. He wraps up his thought by dropping an image of the Voynich manuscript alongside a deadpan note apologizing for the nonsense because it is just a coded joke.

https://oil-glup.ru/threads/hths-high-temperature-high-shear-chto-ehto.204/#post-5043 A scientific plot at T = 293 K displays apparent viscosity against shear rate for three oligomer structures, showing a transition from Newtonian behavior at low shear to non-Newtonian shear-thinning above the critical rate. At the end of the day, tetramers deliver higher baseline viscosity than trimers and dimers across the board before all curves merge into a slope of minus one at extreme shear rates. Chemical sketches on the right depict branched molecular chains for dimer, trimer, and tetramer configurations that dictate these rheological properties.

https://oil-glup.ru/threads/api-sq.79/page-4#post-5042 An ExxonMobil chart illustrates the historical evolution of engine oil performance from 1911 to 2021, showing how base stock and additive technologies advanced alongside stricter API gasoline categories. Early improvements crept along slowly, but emissions and efficiency standards kicked things into high gear starting in the 1970s. The stacked area graph breaks down performance gains into contributions from base stocks and additives, charting the steady climb from SA up to modern SP specifications.
