The invention provides an emulsifying defoaming system and a PVB (Polyvinyl Butyral) resin production method employing the same and relates to an additive and application thereof in a resin production process, wherein the emulsifying defoaming system is composed of an emulsifier and a defoamer; the weight percentage of the emulsifier is 50-99.9%; and the emulsifier is the mixture of sodium hexadecyl sulfosuccinate or octyl phenyl polyoxyethylene ether and sodium alkyl sulfosuccinate. The emulsifying defoaming system is applied so that bubbles generated by stirring while the excellent emulsification effect of the reaction system is achieved; so that therefore, the generation of massive wastes can be reduced and the quality and yield of the product can be improved. Simultaneously, the defoamer applied in the emulsifying defoaming system provided by the invention is also advantages for improving the compatibility of a plasticizer with the resins. The formation of bubbles in the subsequent extrusion curtain coating processing procedure of the resins also can be eliminated in the presence of the defoamer; and the obtained membrane is free of defect apparently.

The invention discloses a seal ring for a special fluororubber motor for nuclear power and a preparation method of the seal ring. The seal ring for the special fluororubber motor for the nuclear power is prepared from the following raw materials in parts by weight: 85 to 90 parts of fluororubber, 5 to 8 parts of acid-acceptor, 2 to 5 parts of compound vulcanizing agent, 8 to 10 parts of reinforcing agent and 1 to 2 parts of additive. The fluororubber motor seal ring is high in mechanical strength, excellent in oil resistance under high temperature, and suitable for a motor of a nuclear-powered ship.

The invention discloses a reactive coating and ink auxiliary agent, which is mainly synthesized from a fluorine-containing acrylate monomer, a double bond-containing organic silicon monomer, an initiator, a chain transfer agent, and a solvent through a radical solution copolymerization process. The product of the present invention can not only effectively reduce the surface tension of the UV-curable coating and prevent the shrinkage cavity of the paint film, but also participate in the cross-linking reaction of the UV-curable coating to prevent it from migrating to the surface of the coating film, so as not to affect the vacuum aluminum plating of adhesion.

The invention relates to the technical field of coatings, in particular to a flexible ceramic coating and a preparation method thereof. The flexible ceramic coating is prepared by mixing a compositionA, a composition B and a composition C, wherein the composition A mainly comprises, by mass, 10-99 parts of acidic silica sol, 0-35 parts of pigments, 0-28 parts of a filler, 0-40 parts of deionizedwater, 0-10 parts of a dispersant, 0-0.7 part of an anti-settling aid, 0.2-0.5 part of a defoaming agent and 0.8-1.5 parts of a wetting leveling agent; the composition B mainly comprises, by mass, 85-93 parts of alkoxy silane monomers, 2-5 parts of a titanate coupling agent and 5-10 parts of an organic solvent; the composition C is an organosilicon-modified acrylic emulsion. The flexible ceramic coating is low in curing temperature, high in toughness and excellent in recoating property, and the phenomena of cracking, shedding and the like cannot occur when the thickness of a film reaches 90 micrometers.

The invention relates to a bio-degradable heat-viscose bi-component filament fiber, which comprises a surface fiber layer and is characterized in that a plurality of core-layer fibers are arranged at the center of the surface fiber layer. The invention further relates to a production method of the bio-degradable heat-viscose bi-component filament fiber, which is characterized by including the following processes of (1) drying poly butylenes succinate and polylactic acid in a vacuum environment; (2) melting and extruding the poly butylenes succinate and the polylactic acid in two screws of a double-screw composite spinning machine, feeding the same into a composite spinning component after being metered by a metering pump, spraying from a composite spinneret plate, cooling to the room temperature, and reeling to form reeled filaments after applying spinning oil; and (3) drafting after balancing the reeled filaments at the room temperature, and accordingly obtaining the bi-component composite filament fiber. The bio-degradable heat-viscose fibers produced by the production method are fine in viscosity, high in strength and better in flexibility and have excellent bio-degradation and absorbability for human bodies.

The invention discloses a heave duty anticorrosion sealing wrapping maintenance method for the surface of a steel component. an originally invalided corrosion prevention material of a substrate is clear away firstly, the surface rust and other pollutants are cleaned, the surface cleanliness reaches an Sa2 level or the same degree, then a quick-drying type zinc-rich silane modified polymer sealantis brushed or scraped, brush coating or scrape coating of a vulcanized silicon-rich silane modified polymer sealant is carried out, and finally scrape coating of a PVF adhesive tape is carried out. The method has the advantages of low surface treatment, corrosion and corrosion resistance sealing, and has the comprehensive characteristics of heat resistance, weather resistance and pollution resistance, on-site operation is simple, fast, efficient, free of dead corners, good in sealing and wrapping appearance decoration performance, and capable of providing the protection life of 20 a or above of the steel component which the steel component is worked in a special harsh corrosion environment such as a heavy-pollution chemical environment, a marine tidal zone and the like, the economic loss caused by frequent maintenance in the fields of a chemical plant, marine engineering and the like is avoided, and the accident risk and abnormal shutdown loss caused by corrosion of equipment or the engineering are avoided.

The invention provides an OLED device containing a light extraction film adhesion promotion layer. The OLED device includes a glass substrate (100), an OLED unit (101) manufactured on the glass substrate; a light extraction film (102) arranged on one side of the glass substrate without the OLED unit; and an adhesion promotion layer arranged between the light extraction film (102) and the glass substrate (100), wherein the unit is a bottom light-emitting device; and the emitted light enters the air through the glass substrate. The invention has the following technical effects that the adhesionpromotion layer is transparent and thin, the light extraction efficiency of the OLED lighting device and the light extraction efficiency of the light extraction film are hardly influenced. The light extraction film of the OLED device prepared by the method has good adhesive force on the glass substrate, and is not easy to wear and scratch; meanwhile, the adhesion promotion layer is easy to prepare, short in time consumption and low in cost, and is particularly suitable for large-scale production.
