The invention discloses a concrete high-efficiency water reducer. The water reducer comprises the following raw materials in parts by weight: 20-40 parts of unsaturated alcohol-polyoxyethylene ether,10-30 parts of sodium lignin sulfonate, 10-20 parts of acrylic acid, 5-10 parts of modified starch, 3-8 parts of aloe gel, 2-6 parts of cyclodextrin, 2-5 parts of cross-linked povidone, 2-5 parts of zinc gluconate, 1-3 parts of sodium polystyrenesulfonate, 1-3 parts of sodium alginate, 0.5-2 parts of graphene oxide, 0.2-1 part of sodium silicate, 0.1-0.5 part of a defoaming agent and 3-5 parts ofan initiator. The high-efficiency water reducer prepared by the method is good in stability, and can increase workability of concrete when used in the concrete. In addition, the water reducer can be mixed with other water reducing agents for use, the water adding amount is reduced, the solidification time of concrete is shortened, and strength of the concrete is improved.

The invention discloses an anti-corrosion power protection pipe which is characterized by being prepared from the following raw materials in parts by weight: 100-130 parts of polyvinyl chloride, 2-4 parts of magnesium hydroxide, 0.1-0.4 part of stearic acid, 6-10 parts of calcium carbonate, 0.2-0.5 part of sodium lignosulfonate, 1-2 parts of nano antimony trioxide, 0.5-1 part of sodium oleate, 0.4-1 part of a silane coupling agent kh550, 0.5-0.8 part of hexamethylphosphoramide, 1-2 parts of a quartz powder, 2-3 parts of wollastonite fiber, 1-2 parts of an anti-aging agent 4010, 2-3 parts of urea, and a proper amount of water. The added hexamethylphosphoramide, quartz powder, wollastonite fiber and urea are mixed under certain conditions, so that the dispersion, compatibility and the like of a filler in PVC are promoted to a great extent, corrosion resistance, aging resistance, flame retardancy, and high mechanical strength and toughness are also improved, and the service life of the anti-corrosion power protection pipe is prolonged.

The invention relates to a filter material used for sewage treatment and particularly relates to a high-efficient composite filter material prepared by blending melt-blown polypropylene with modified pseudo-boehmite and used for sewage treatment and a preparation method thereof. The filter material is prepared from following raw materials, by weight: 1-2 parts of manganese sand in 200-300 meshes, 15-18 parts of micro powder of pseudo-boehmite in 200-300 meshes, 30-35 parts of polypropylene, 1-2 parts of a titanate coupling agent, 0.4-0.5 parts of sodium lignin sulfonate, 1-2 parts of polyether-modified silicone oil, 8-10 parts of nano bamboo charcoal powder, 1-2 parts of yttrium sol being 8-10% in solid content, 0.01-0.02 parts of lanthanum-series rare earth salt and 30-40 parts of water. In the invention, the modified pseudo-boehmite-based composite micro powder is supported onto the modified polypropylene master batch melt-blown filaments to prepare the filter material having a stereoscopic network structure. The filter material is excellent in purification effect, is stable and high-efficient in performances, is changeable in shape, is not liable to damage and can be used repeatedly.

The invention discloses a method for producing a high-sulfur petroleum coke slurry additive, which comprises the following steps: uniformly mixing sodium lignin sulfonate, sodium dodecyl benzene sulfonate, a sodium naphthalene sulfonate formaldehyde high-molecular polymer, ethylene glycol and water, and heating; adding carboxymethyl cellulose and sodium hydrogen sulfite, and stirring to obtain a petroleum coke slurry additive; the method can obviously improve the concentration of the petroleum coke slurry, reduce the bleeding rate, improve the stability and efficiently utilize the petroleum coke in an environment-friendly manner, is suitable for gasification or incineration of the petroleum coke, and has creative significance in efficient utilization of the high-sulfur petroleum coke.
