摘要:
The present invention describes a pipe sealing compound/adjunct lubricant used to prevent gas or liquid leaks when applied to pipe threads and other connections of the same. The compound relies on silicone oil lubricant(s) and one or more friction modifier(s), viscosity builder(s) and filler material(s). The compound contains a viscoelastic liquid that does not have a curing phase and is resistant to hardening and/or drying. The compound is chemically resistant to a wide variety of liquids and gases, is food safe and can withstand extreme high or low temperatures and precipitous temperature fluctuations. The compound has been found to exhibit an inverse pressure to leak rate phenomena.

Disclosed is food-grade lubricating grease and a method for preparing the same, belonging to the technical field of lubricating grease. The food-grade lubricating grease is prepared from the following components in percentage by mass: 75% to 85% of food-grade white oil, 6% to 16% of stearic acid, 2.0% to 3.0% of benzoic acid, 4.7% to 8.7% of aluminum isopropoxide, 1.0% to 1.5% of water and 1.0% to 7.0% of nano-PTFE, and has good extreme-pressure, abrasion-resistant and friction-reduction properties, a last non-seizure load (PB) reaching 411.6 N, a sintering load (PD) reaching 1,960 N, and a friction coefficient reduced by 18.5%. The lubricating grease can be used for a food production industry and in household food appliances, the service life of a device and the service life of the food-grade lubricating grease are effectively prolonged, and meanwhile, food security is guaranteed to a certain degree.

摘要:
Disclosed is a component-replaceable water ring vacuum pump in which inner components within a head unit may be disassembled and replaced without separation of the head unit from a main body, thus shortening an operation time and improving operation efficiency through prevention of leakage of an inner liquid during a replacement process. The water ring vacuum pump includes a main body provided with a shaft, a rotor rotated together with the shaft within the main body, a head unit coupled to both sides of the main body, a guide bearing provided within the head unit, and a mechanical seal configured to block inner gas. A bearing bracket to support the guide bearing is detachably fastened to one side of the head unit by a bolt, and an inner cap and an outer cap are assembled to the inner and outer surfaces of the bearing bracket by fixing bolts.
摘要:
A reaction product, useful as a viscosity index improver in a lubricating oil, reacting: a) an oil soluble ethylene-alpha olefin copolymer comprising from 10 to less than 80 weight % ethylene and greater than 20 up to 90 weight % of at least one C3 to C28 alpha olefin, having a number average molecular weight from 5,000 to 120,000 and grafted with 0.5 to 5 weight % of an ethylenically unsaturated acylating agent, with b) a hydrocarbyl substituted poly(oxyalkylene) monoamine of the formula: R1—(O—CHR2—CHR3)x-A wherein: R1 is a hydrocarbyl group having from 1 to 35 carbon atoms; R2 and R3 are each independently hydrogen, methyl, or ethyl and each R2 and R3 are independently selected in each —O—CHR2—CHR3— unit; A is amino, —CH2amino or N-alkyl amino having 1 to 10 carbon atoms; and x is an integer from 2 to 45.

摘要:
A solid lubricant, consisting of solid perfluorocarbons, with linear or substantially linear carbon atoms chain, containing from 10 to 20 carbon atoms and having a value of surface tension ranging from 13 to 15 dyne/cm, is obtained by dimerization or co-dimerization of perfluorocarbonsulphonyl halogenidesC.sub.n F.sub.2n+1 SO.sub.2 X(in which X represents an atom of halogen), having a linear or substantially linear chain of carbon atoms and bearing the --SO.sub.2 X group at one end of the chain, operating at high temperature, with short reaction times, and preferably in the presence of a metal catalyst.The solid perfluorocarbon lubricant can be used, if desired as a mixture with paraffinic wax, on sliding surfaces, particularly consisting of a polymeric material either porous or made porous.

摘要:
One aspect of the disclosure relates to a sliding member. The sliding member includes: a first sliding portion having a first lubricant placed between first parts of a first friction sliding mechanism; and a second sliding portion having a second lubricant placed between second parts of a second friction sliding mechanism. The first sliding portion has a lubricant feed port from which the first lubricant is fed, and the second sliding portion has no lubricant feed port from which the second lubricant is fed. The first lubricant contains base oil and an additive. The second lubricant contains base oil and an additive containing conductive carbon. The second lubricant contains a relatively larger amount of conductive carbon than the first lubricant.

The present disclosure relates to an automotive slide member including a first slide portion having a first lubricant applied between first portions of a first friction slide mechanism, and a second slide portion having a second lubricant applied between second portions of a second friction slide mechanism. The first slide portion is arranged at a part to be touched by an operator who attaches the automotive slide member to an automobile or a user of the automobile. The second slide portion is arranged at a part that is not touched by the operator who attaches the automotive slide member to the automobile or the user of the automobile. The second lubricant contains a relatively larger amount of conductive carbon than that of the first lubricant.
