The invention discloses a self-buffering type composite defluorination preparation prepared by resource utilization of chemical sludge, and belongs to the field of sewage treatment preparations. The novel self-buffering type composite defluorination preparation provided by the invention has the capabilities of deeply removing fluorine ions and adjusting pH by utilizing the adsorption, net capturing and other effects of Si-Al-OH colloid generated after phosphorus polysilicate aluminum iron is hydrolyzed, phosphate radical vacancy and Ca < 2 + > and buffering property of calcium carbonate in chalk; the self-buffering type composite defluorination preparation is put into photovoltaic wastewater with the inlet water fluorine concentration of 14.2 mg / L and the pH value of 7.8, and after static settlement is conducted for 30 min, the outlet water fluorine concentration is lower than 1.5 mg / L, and the pH value is still kept to be 6.5 or above.

This invention belongs to the field of welding auxiliary materials technology, specifically relating to a ring-shaped gasket material for pipe welding. From the radial inner side to the radial outer side, it comprises a fusible support layer, a high-temperature resistant skeleton layer, a flexible bonding layer, and an active metallurgical layer. The fusible support layer is composed of a eutectic salt of sodium chloride, potassium chloride, and sodium silicate, which softens or partially melts at 650℃-750℃; the high-temperature resistant skeleton layer is a continuous alumina fiber woven and sintered mesh structure; the flexible bonding layer is a composite pressed layer of graphite worms and aluminosilicate fiber felt; and the active metallurgical layer is a coating layer containing titanium dioxide, cryolite, ferrosilicon powder, ferromanganese powder, and aluminum powder. This gasket addresses three practical engineering problems in pipe circumferential welding: assembly rigidity, high-temperature load-bearing capacity, and curved surface fit. Through the progressive and overlapping effect of the four-layer structure, it allows for a certain degree of asynchronous response among the layers, accommodating a certain range of assembly tolerances and welding parameter fluctuations. After welding, there are virtually no obstructions remaining inside the pipe, and the weld root is well-formed.

This application relates to the field of flame-retardant cable technology, and discloses a B1-grade halogen-free, low-smoke flame-retardant special cable and its preparation method. The cable includes a cable core consisting of at least one insulated conductor. The cable core is covered from the inside out with a wrapping filling layer, a heat insulation layer, an oxygen barrier layer, a flame-retardant layer, and an outer sheath layer. The wrapping filling layer is made of aluminum silicate fiber rope, the heat insulation layer is made of ceramicized silicone composite tape, the oxygen barrier layer is made of halogen-free, low-smoke, flame-retardant polyolefin material, the flame-retardant layer is made of fire-resistant mica tape, and the outer sheath layer is made of an irradiated cross-linked halogen-free, low-smoke, flame-retardant polyolefin material containing ethylene vinyl acetate copolymer, metallocene-catalyzed linear low-density polyethylene, aluminum diethylphosphinate, melamine cyanurate, and an irradiation cross-linking agent. During preparation, the insulated conductor, wrapping filling layer, heat insulation layer, oxygen barrier layer, flame-retardant layer, and outer sheath layer are formed sequentially, and the outer sheath layer is irradiated and cross-linked. This technical solution combines flame retardancy, low smoke, low corrosion, and structural stability.

This invention discloses a heated cigarette device component with a heat-insulating coating, its preparation method, and a cigarette device containing the component. The component includes a metal substrate and a silicate heat-insulating coating coated thereon. This coating is formed by coating, curing, and sintering a heat-insulating slurry containing water glass, specific fillers, and additives. The filler is composed of aluminosilicate fibers, mica powder, hollow glass microspheres, rutile titanium dioxide, low-melting-point glass powder, talc powder, and zirconium dioxide in a specific mass percentage.
