The steel cord (30) comprising a core strand (32) and three or more outer strands (34) twisted around said core strand (32). The outer strands (34) are multi- layer strands comprising multiple steel filaments arranged in an outer strand core (36) and at least one outer strand layer (38, 40), the steel filaments in the outer strands have a round or substantially round cross-section. At least one outer strand (34) comprises flattened portions (52) and non-flattened portions (54) along its length. The flattened portions create spacing S between adjacent outer strands (34) and gaps G between adjacent filaments in the outer strand (34), which improves rubber penetration and elongation of the steel cord (30), and finally improves the impact resistance of the steel cord (30). Besides, the flattened portions (52) limit the flare of the steel cord.

In view of the facts that a particle size of kainite is fine, viscosity of ore pulp will be obviously increased, and an adsorption activity of the kainite on a collecting agent is strong, for decomposed slurry of carnallite, a kainite flotation reagent is firstly employed to perform flotation on the kainite, and the kainite is separated from a flotation system, such that excessive consumption of the flotation reagent by the kainite is avoided, a capping behavior between the kainite and sodium chloride is broken. And then a certain amount of potassium chloride flotation collecting agent is employed to achieve efficient separation of the potassium chloride and the sodium chloride.

[WEI HONGZHEN] CN A fireproofing cover for a light fitting includes a cover top 1, a bevel edge 2, a cover enclosure 6 and a cover skirt 9. On the bevel edge there are heat sinks made up of two layers: an intumescent underlayer 8 and a ceramic fiber paper upper layer 4. The cover top, bevel edge, cover enclosure and cover skin are made of glass fiber cloth, one side of which is surfaced with fireproofing coat. Inside the cover enclosure there is an inner cover support bracket 14. The intumescent layer for the said heat sink uses ceramic fiber, 32-mesh expandable graphite and polyvinyl alcohol as the main raw materials, and can completely and instantly seal the air holes on the heat sinks to achieve the goal of extinguishing fire automatically.

[WEI HONGZHEN] CN Abstract The present invention provides a fireproofing cover and a special intumescent material for its heat sinks. The fireproofing cover can stop fast spreading of fire, 5 causing flame to have no burning conditions and go out by itself. The present fireproofing cover includes the cover top, bevel edge, cover enclosure and cover skirt. On the bevel edge there are the heat sinks. The heat sinks are made up of two layers: the intumescent piece underlayer 10 and the ceramic fiber paper upper layer. The cover top, bevel edge, cover enclosure and cover skirt are made of the glass fiber cloth, one side of which is surfaced with fireproofing coat capable of resisting high temperature. Inside the cover enclosure there is an inner cover support 15 bracket. On the cover enclosure there is a mounting support. The special intumescent piece for the said heat sink uses the ceramic fiber, 32-mesh expandable graphite and polyvinyl alcohol as the main raw materials. And the 32-mesh expandable graphite has a content of 20%-50% in 20 the material. The special intumescent piece for the heat sinks used on the fireproofing cover of the present invention has an excellent expansion performance, and it can completely and instantly seal the air holes on the heat sinks of the fireproofing cover as to achieve the 25 goal of extinguishing fire automatically.
