Plastic Mini-ball Solid Lubricant

plastic mini-ball solid lubricant
hzn-102 plastic mini-ball(micro-sphere) is the cross-linking copolymer of styrene and divinylbenzene. it is a kind of transparent or semi-transparent white sphere. the particle size is between 0.1mm-2.0mm. the softening point is at centigrade 200 degree. it is resilient, anti-extruding, no foaming, abrasiveless that will not abrade the facilities. it has no fluorescence and is insoluble in water, oil, acid and alkali. in the drilling fluid it appears inertia and react with none of other ingredients. it has no toxicity, does no harm to the human and animals, and will not pollute the environment. the mechanism: the plastic mini-balls which distribute in the drilling fluid will adhere to the sidewall and form innumerable "mini-bearings" when the mud cake is taking shape, which changed the contact manner between the drilling tools and the sidewall from surface-contact to point-contact and then achieve the goal of block-reducing, lubricating and anti-seizing.
