The invention belongs to control of feedwater treatment and disinfection by-products and particularly relates to a feedwater treatment and disinfection process by converting multipoint free chlorine into chloramine. On the basis of structures of precipitation-disinfection process stages of original conventional feedwater treatment processes of a conventional drinking water treatment plant, chlorine is fed for disinfection at two or three points, ammonia nitrogen is required to be fed at once after chlorine is feed at the last point, and accordingly, treated water can be disinfected further by converting the free chlorine into chloramine in place. By the feedwater treatment and disinfection process, disinfection by-products can be effectively controlled, the COD (chemical oxygen demand) can be reduced to a great extent, and the feedwater treatment and disinfection process have great action on preventing forming of biomembranes of a filter tank and nitration of a pipe net is realized. Meanwhile, chlorine feed quantity can be adjusted flexibly according to the characteristics of water quality by means of multipoint chlorine feeding, and accordingly, severe fluctuation of residual chlorine quantity and ammonia nitrogen feed quantity is reduced, and safe and stable water supply of large and mid-size cities can be guaranteed effectively.

The invention discloses a fast-drying cemented carbide molding agent and its mixing process, which is composed of the following components in weight percentage, wherein: paraffin wax, 50-60%; oleylamine, 1-5%; soybean oil , 5 to 10%; n-octane, the balance. The present invention introduces soybean oil lubricating components, through reasonable control of the ratio of plasticizing components and solvent components, endows the extrusion feed with better plasticity and viscosity, and ensures that the extruded billet has better shape maintenance properties; By introducing n-octane as a solvent, n-octane has good miscibility with the molding agent of paraffin wax system compared with the existing solvents, and there will be no segregation of the molding agent after mixing; at the same time, n-octane has moderate volatility, ensuring To ensure the stability of the mixture, it can realize fast drying in the shade or drying.

The invention relates to the technical field of transfer films, in particular to a super-mirror anti-scratch transfer film and a preparation method thereof. The preparation of the super-mirror anti-scratch transfer film includes the following preparation steps: taking a PET film; mixing water-based polyurethane, an alcohol organic solvent and water Mixed and stirred evenly by weight, is modulated into water-based release coating; the prepared water-based release coating is coated on the surface of the PET film to form a water-based release coating; after the water-based release coating is dried, it is a water-based release layer, A PET film semi-finished product loaded with a water-based release layer is obtained; the outer surface of the water-based release layer is coated with an information coating to form an information coating; the surface of the information coating is sequentially provided with a vacuum aluminized layer and an adhesive layer, A finished super-mirror anti-scratch transfer film is obtained. The super-mirror anti-scratch transfer film of the invention has strong scratch resistance, high specular gloss, simple preparation process and high production efficiency.

The invention relates to a method for recrystallizing tylosin tartrate. The method comprises the following process steps: firstly extracting a tylosin tartrate refined solution by using dichloromethane, slowly and dropwise adding sec-butyl acetate in a dichloromethane phase obtained after phase splitting until separating out crystal; then centrifuging and drying the crystal. According to the characteristic that the tylosin tartrate can be dissolved in the dichloromethane but not be dissolved in the sec-butyl acetate, the tylosin tartrate refined solution is subjected to recrystallization treatment by adopting a dichloromethane extracting and sec-butyl acetate crystallization separation method; the yield of a product obtained through the method disclosed by the invention is up to 97.0 percent or more, and the content of a tylosin component A is up to 94.0 percent or more; the method has the characteristics that technological treatment is simple, no pollution is generated, the cost is low, the period is short, the yield of the obtained product is high, the content of the tylosin component A is high, the quality is high, and the like.

The invention relates to an ice-sense tea flavor essence and use thereof. The iced tea flavor essence, in parts by weight, contains the following aroma components: 3.06 parts-3.74 parts of ice-sense flavors; 1.17 parts-1.43 parts of jasmine flavors; 0.32 parts-0.41 parts of floral flavors; 0.21 parts-0.27 parts of tea flavors part; and 0.05-0.08 part of auxiliary flavor. The iced tea flavor has a pleasant iced feel and a pronounced matcha aroma.

The invention discloses rust preventive oil suitable for a valve. The oil is prepared by mixing, stirring, heating and dissolving sodium petroleum sulfonate, zinc naphthenate, lanolin, sodium petroleum sulfonate, zinc naphthenate and aviation kerosene, wherein the sodium petroleum sulfonate serves as a main rust preventing agent; the zinc naphthenate serves as an auxiliary rust preventing agent; the lanolin serves as a main film forming matter; the sodium petroleum sulfonate and the zinc naphthenate serve as auxiliary film forming matters; the aviation kerosene serves as the basic oil of the rust preventive oil; and the rust preventive oil comprises 2 to 6 weight parts of sodium petroleum sulfonate (with a molecular weight of 466), 1 to 4 weight parts of zinc naphthenate, 4 to 8 weight parts of lanolin and 82 to 93 weight parts of aviation kerosene. The rust preventive oil overcomes the defects of poor rust preventive capability, relatively higher viscosity, easy adhesion to other foreign matters, over gross weight of oil films used on the valve, difficulty in drying by hot air of 60 DEG C within 3 minutes, bad odor and the like of the conventional rust preventive oil for the valve.

The invention discloses special varnish for musical instruments and a preparation method thereof. The special varnish for the musical instruments is a four-component coating; a PE (polyethylene) coating and a PU (polyurethane) coating are combined in the formula and give full play of respective advantages, and the defects of single use of the coatings are avoided, thus solving the defects in single use of the conventional products for musical instrument manufacturers. The special varnish has the advantages of high hardness up to over 2H, excellent fullness, good color change property, no greening property of PE, polishability and thickened viscosity for 5 seconds within 2 hours, thus solving the problem of use time of a single PE component. The special varnish for the musical instruments can be sprayed by an electrostatic machine, can be widely applied to the musical instruments such as a guitar, a loudspeaker box, a piano and the like, and has good comprehensive property and good constructability, thus being beneficial to large-scale popularization.
