Abstract:
Provided are a formulation which creates protection layers on the metal friction and wear surface and a method for preparing the same. The formulation provided here comprises 45-99 parts laminar hydroxyl silicate powders, 1-50 parts formulation which creates protection layers on the metal surface and method for preparing the same and 0.05-6 parts carbonization-graphitization catalyst, calculated by weight. Also provided is method for preparing the same. The formulation provided here could create a friction-reducing and wear-resistant nanocrystal protection layer in situ on the metal friction and wear surface, at the same time, it has high hardness of cermet and elastic modulus of formulation which creates protection layers on the metal surface and method for preparing the same high grade alloy steel.
Abstract:
Lubricant formulations comprising a phospholipids such as lecithins and a low hydrophobic lipophilic balance (HLB) surfactant provide improved rheological properties for coating a rapidly moving web, such as a paper web. The low hydrophobic lipophilic balance (HLB) surfactant is preferably an alcohol ethoxylate having an HLB value of between 7 and 10 or more preferably between 7.5 and 9.5. The lubricant formulations of the invention are preferably applied to the paper web as part of a coating mixture. The lubricant is well-suited for short-dwell coating methods.

The invention relates to a stable aqueous particle dispersion, wherein the particles in an aqueous medium are stabilised by a polymer stabiliser embodied in the form of a polycarboxylate.
Abstract:
An anti-seize composition which is non-flowable and dimensionally stable at temperatures greater than about 120° F. and dispensable at room temperature without the application of heat is provided. The composition includes a solid anti-seize lubricant, such as of metallic copper, metallic nickel, metallic aluminum, metallic lead, metallic zinc, graphite, calcium oxide, calcium carbonate, calcium fluoride, calcium stearate, lithium, molybdenum disulfide, boron nitride, barium sulfate, or combinations thereof. The anti-seize lubricant is dispersed in a carrier which is a solid at about room temperature. The carrier includes a grease with an ASTM D 217 penetration at 25° C. from about 200 to about 400 mm, a matrix material, and a naphthenic petroleum oil having a viscosity of less than about 300 SUS at 100° F. and having an API gravity at 60° F. from about 23 to about 25. The matrix material is a polymeric material. Optionally, a refined petroleum wax may also be included.
