Composition of compound calcium sulfonate-based lubricating grease for improving high-temperature performance and preparation method thereof
InactiveCN104327906AGood high temperature resistanceImprove retentionThickenersTemperature resistanceSalicylic acid
The invention relates to a composition of compound calcium sulfonate-based lubricating grease for improving high-temperature performance and a preparation method thereof. The composition is prepared from a high-alkalinity calcium sulfonate cleaner, methanol, lithium hydroxide, salicylic acid, C12-C16 salicylic acid and base oil. The lubricating grease provided by the invention has relatively good high-temperature resistance and meets the seepage loss of ASTM D4290 and ASTM D1263 (industrial standard is SH / T0326). Experiments show that the seepage loss ranges from 5 to 10 which is obviously better than that (15-35g) of marketed products. The improving method provided by the invention can be used for prolonging the retentivity of the lubricating grease in a friction pair so as to ensure the operating reliability of equipment.

Polyester silk with function of preventing radiation
InactiveCN105297154AHigh strengthImprove wear resistanceSpinnerette packsFilament forming substance formingPolyesterEngineering
A polyester silk with a function of preventing radiation relates to the technical field of polyester silk production and can be machined according to the following steps of (1) preparing basic filaments, (2) pre-orientating POY filaments and polyester full-stretch filaments PDY on the same rolling rack, (3) forming six equal-side and angle filament spraying slits on a filament spraying plate, (4) enabling PDY to enter a traction area from the same side of a pair of traction rollers, (5) compositing the basic filaments, the POY and the PDY filaments in the step (4) to a filament guide roller, (6) compositing the basic filaments, the POY and the PDY filaments to a beam of fialments and tracting the beam of filaments to polyester filaments via a heating large-diameter roller and a non-heating small-diameter roller. The side interval of two adjacent filament spraying slits is 0.05 to 0.07mm. The polyester filament has high strength, great wear-resistance and excellent radiation-proof effect.
