Water-based cutting fluid used in slice machining of hard brittle crystal material and preparation method of water-based cutting fluid

The invention discloses a water-based cutting fluid used in slice machining of a hard brittle crystal material, comprising the following compositions: base oil, organic amine, organic acid, synthetic ester, emulsifier, rust and corrosion inhibitor, dispersion flocculation and hard-water resisting agent, antiseptic bactericide, antifoaming agent, coupling agent, adjuvant and a proper amount of water. Aiming at the machining techniques of inner circle slicing and outer circle slicing, the water-based cutting fluid has good generality, lubricity, strong antirust property and a long service life; when the cutting fluid is used, the machining situation can be observed easily, the cooling property is good, the cleaning and the permeability are strong, cuttings subside easily, and the machining problems of machining error, crack and the like caused by cutter blocking, abrasion and the like are solved; according to the invention, the problems that cuttings are easy to adhere and suspend, a cutter is seriously abraded, a machined product cracks easily, the accuracy is not high, the machining efficiency is low, the later period cleaning is complex and the like existing in the current slice machining of the hard brittle crystal material are solved, and further, a machine bed is protected, and the cost is reduced.

Controllable crystalline form titanium dioxide and graphite alkene composite material with high efficient photoelectricity activity and preparation method thereof

The invention discloses controllable crystalline form titanium dioxide and a graphite alkene composite material with high efficient photoelectricity activity and a preparation method thereof. The composite material is formed by mixing TiO2 powder and graphite alkene or scattering the TiO2 powder in oxidized graphite alkene dispersing agents to perform hydro-thermal reaction. The mass ratio of TiO2 powder and graphite or graphite alkene is 1:1 to 500:1. The preparation method is simple, low in cost and environmental-friendly. The controllable crystalline form titanium dioxide and a graphite alkene composite material with high efficient photoelectricity activity can control crystalline form of the obtained TiO2 according to the ratio of alcohol and water or amount of titanium sources. When the amount is amplified, the controllable crystalline form titanium dioxide and a graphite alkene composite material with high efficient photoelectricity activity have good performances. After the graphite alkene is composed, photocatalysis is greatly improved. All obtained products are applied to fields of dye sensitization solar cells, catalysts, lithium ion cells, sensing and the like.

Polymetallic-ore-dressing wastewater coagulating sedimentation device and method

The invention discloses a polymetallic-ore-dressing wastewater coagulating sedimentation device and a polymetallic-ore-dressing wastewater coagulating sedimentation method. The process comprises the following main devices: a coagulation reaction tank, a flocculation, sedimentation and separation integrated device and a separation wall. The process flows are as follows: the polymetallic-ore-dressing wastewater fully reacts with a coagulant in the coagulation reaction tank to enable the wastewater to be destabilized quickly and flocculated efficiently; the coagulated wastewater enters the flocculation, sedimentation and separation integrated device to fully react with coagulant aid to further perform flocculation coarsening and fast sedimentation, so that high-efficiency mud-water separation is realized; and the processed wastewater is discharged directly or deeply purified by the separation wall to be recycled. The device and the method can effectively solve the problems that in the polymetallic-ore-dressing wastewater treatment, the flocculent precipitation is instable, the flocculation time and sedimentation time are long and the like, and can quickly perform destabilization and realize high-efficiency flocculation, high-efficiency sedimentation and high-efficiency separation. The device and the process flow are simple and practical, the wastewater purifying efficiency can be remarkably improved and the effluent water quality is stable and reaches the standard.

Magnetic microsphere resin for removing nitrate nitrogen selectively, and preparation method thereof

The invention discloses magnetic microsphere resin for removing nitrate nitrogen selectively, and a preparation method thereof, and belongs to the field of ion exchange resin. The resin consists of a resin skeleton, and magnetic granules wrapped in the resin skeleton; and the resin skeleton has a basic structural formula shown in the specification, wherein B is a quaternary ammonium salt group for adsorbing the nitrate nitrogen selectively, the saturation magnetization intensity of the quaternary ammonium salt group is between 5 and 30 emu / g, the exchange capacity of strong base is between 3.0 and 4.5 mmol / g, the exchange capacity of weak base is between 0.5 and 1.5 mmol / g, and the average grain diameter of the resin is between 50 and 500 micrometers. The resin is synthesized by a suspension polymerization method; acrylate monomers are mixed with a pore-forming agent and an initiator to form an oil phase; after being mixed with the magnetic granules uniformly, the mixture is subjectedto suspension polymerization with an aqueous phase mixed with a dispersing agent to form the magnetic polymer granules, and the magnetic polymer granules are subjected to aminolysis and alkylation toform the resin serving as a finished product. The resin can adsorb negative ions such as nitrates, nitrites and the like in a water body selectively, so the magnetic microsphere resin has a bright application prospect in fields of drinking water treatment, groundwater remediation and the advanced treatment of urban domestic sewage.
