摘要:
Methods, systems, and processes are used to prepare novel ceramic composite structures that are strong, durable, light-weight, high performance and suitable for a myriad of industrial applications, including, but not limited to, ceramic plates of material suitable for use as ballistic armor. The low manufacturing costs of the processes disclosed provide cheaper, faster ways of producing ceramic matrix composites at lower temperatures and allow for the existence of composite materials and structures which currently are not available.
摘要:
The engine oil degradation inhibitor produced by mixing a fermentation bacterium and a soil bacterium cultivated separately in a culture medium made from molasses diluted with water, and then adding an organic fat.
摘要:
A method for making compatibilizer for a concentrated viscosity index improving polymer blend includes polymerizing a mixture of (meth)acrylate monomers in the presence of a polyolefin polymer. A concentrated blend of viscosity index improving polymers includes a non-nitrogenous dispersant poly(meth)acrylate copolymer, a polyolefin copolymer, the compatibilizer and a hydrocarbon diluent.
摘要:
An antirust, anticorrosion grease composition comprising a major amount of a fluorinated polysiloxane base fluid, a minor amount of a fluorocarbon polymer thickening agent, and a rust and corrosion inhibiting amount of a benzimidazole.
摘要:
A motor configured to power an electric or hybrid vehicle, comprising a lubricant oil composition including a polyalkylene glycol (PAG) base oil, at least one of a poly-alpha-olefin (PAO) and an ester, and an additive package that includes at least a sulfur-based extreme pressure agent.
摘要:
Methods, processes, systems, devices and apparatus are provided for additive manufacture resulting in the 3D printing of novel ceramic composites. Additive manufacture or 3D printing of bulk ceramic and ceramic composite components occurs at considerably lower temperatures and shorter manufacturing intervals than the current state of the art. The methods, processes, systems, devices and apparatus and selection of precursor resins produce ceramic and ceramic composite material systems which have not been produced before by 3D printing.
摘要:
Methods for producing Polymer Derived Ceramic (PDCs) particles and bulk ceramic components and compositions from partially cured gelatinous polymer ceramic precursors and unique bulk composite PDC ceramics and unique PDC ceramic particles in size and composition. Methods of making fully dense PDCs over approximately 2 μm to approximately 300 mm in diameter for applications such as but not limited to proppants, hybrid ball bearings, catalysts, and the like. Methods can include emulsion processes or spray processes to produce PDCs. The ceramic particles and compositions can be shaped and chemically and materially augmented with enhancement particles in the liquid resin or gelatinous polymeric state before being pyrolyzed into ceramic components. The resulting ceramic components have a very smooth surface and are fully dense, not porous as ceramic components from the sol-gel process.
摘要:
A two-stroke, cross-head, slow-speed, compression-ignited marine engine is operated by (i) fuelling it with a diesel fuel, as a pilot fuel, and with a low sulphur fuel, as a main fuel; and (ii) lubricating the engine cylinder(s) with a lubricant having a BN of 20 or less and having a detergent additive system comprising at least two different metal detergents each having one surfactant group selected from phenate, salicylate and sulphonate, or one or more complex metal detergents containing two or more different surfactant soap groups selected from phenate, salicylate and sulphonate.
摘要:
Additives useful for reducing the coefficient of friction in lubricants, greases, or cosmetic formulations, and useful as a substitute for talc and as an anti-misting material are obtained by subjecting a raw plant material, such as cotton, to a dosage of radiation from an electron beam source. The irradiated plant material is subsequently fragmented, or micronized, to product the friction-reducing additive with a reduced diameter capable of reducing the coefficient of friction, used for anti-misting or as a substitute for talc in a variety of applications.
摘要:
There is disclosed a group of lubricant additives that have improved oxidative stability, high viscosity and relatively lower cost and that comprise telomerized vegetable oils having no more than 4% polyunsaturated fatty acids. There is also disclosed sulfurized and phosphite adduct derivatives of telomerized vegetable oil for use as lubricant additives.
