The invention specifically relates to a seabuckthorn solid beverage, which comprises the following components by weight fraction: 19-23 parts of seabuckthorn powder, 1-3 parts of dry beet juice powder, 13-14 parts of sweetener, 25-45 parts of stabilizer, 1-2 servings of konjac flour. After brewing, the seabuckthorn solid beverage prepared by the present invention is uniform and fine, free of foreign matter and layered, has the unique aroma of seabuckthorn and is thick, has the natural orange color of seabuckthorn, and moderate taste.

The present invention combines the field of floor heating with the wet forming technology of papermaking, and proposes a floor heating heating chip material, which is made by mixing and pulping plant fibers and carbon fibers, dispersing, refining, and then slag removal and screening. Its uniform structure and morphology make the paper surface smooth, wrinkle-free, and foreign matter-free; furthermore, through the application of graphene coating, floor heating is given the characteristics of high heat conversion efficiency, high efficiency and energy saving, faster and more uniform heating.

The invention discloses a production method of a knitted cloth sanitary napkin. The specific steps are as follows: composite the two-wing material with the surface layer: spray structural glue on the back of the two-wing material and composite the surface layer, send it to a conveyor belt and wait for it to be composited with the core body, and the surface layer It is pure cotton knitted fabric; the core body is combined with the bottom film: first spray structural glue on the bottom film, and then fold the core body in three. In the production method of a knitted cloth sanitary napkin according to the present invention, each layer is gradually compounded step by step, which increases the composite connection strength of the sanitary napkin, makes the production of the sanitary napkin have a sense of hierarchy, and can increase production efficiency while increasing production efficiency. The composite strength of large sanitary napkins, the surface layer is pure cotton knitted fabric woven with 100% pure cotton JC50S cotton yarn, and through dyeing, finishing and slitting processing to meet the production needs of sanitary napkins, weaving hygienic, no foreign matter, no oil stains 1. The pure cotton knitted fabric without serious defects improves the feeling of using the sanitary napkin in direct contact with the skin, provides a softer surface layer, and is better for people to use.

The invention relates to a repair tooling of a hot-blast branch pipe lining of a hot-blast furnace and a repair method thereof. The repair tooling comprises split type structural support track beams including a left support track beam and a right support track beam, wherein the support track beams are connected with end flanges of hot-blast branch pipes, two sliding trolleys are installed on the support track beams in a sliding mode, and insulation blind plates are respectively hoisted on each sliding trolley. The hot-blast branch pipe lining of the hot-blast furnace is repaired in a hot state of the hot-blast furnace by utilizing the repair tooling of the hot-blast branch pipe lining of the hot-blast furnace, and the repair method mainly comprises the following steps that after the blast furnace blows down, firstly, the hot-blast furnace is put in a cold stoking state, the condition that the states of all valves meet operation requirements on site is confirmed, the lining repair tooling is installed, an insulation wall is built, the lining is repaired, the repair tooling and the insulation wall are disassembled, and the hot-blast furnace is reassembled and started to normally supply air. According to the scheme, the lining of the hot-blast furnace cannot be influenced by low temperature, and the repair can be quickly realized; in an actual repair process, the safety of operating personnel is guaranteed, and the repair difficulty is reduced; additionally, a hot-blast valve is installed with time saving and labor saving, and the operating efficiency is greatly improved.

The invention discloses a polyethylene film with high peeling strength on a non-aluminized surface of VMPET and a preparation method thereof. The polyethylene film comprises the following substances by weight: 5 to 15% of hydrogenated dimer acid / rosin-based polyester polyamide, 2 to 5% of maleic anhydride-grafted polyethylene and 80 to 93% of polyethylene, wherein the hydrogenated dimer acid / rosin-based polyester polyamide is prepared by reacting carboxyl-terminated polyamide with dihydric alcohol; the carboxyl-terminated polyamide is prepared by reacting hydrogenated dimer acid with maleic rosin acid and diamine, a weight ratio of the hydrogenated dimer acid to the maleic rosin acid is 5: 5 to 3: 7, and a ratio of the sum of the mole numbers of carboxyl groups in the hydrogenated dimer acid and the maleic rosin acid to the mole number of amino groups in the diamine is 1: 0.6-0.8; and a ratio of the mole number of hydroxyl groups in the dihydric alcohol to the mole number of carboxyl groups in the carboxyl-terminated polyamide is greater than or equal to 1.8: 1. The prepared polyethylene film in the invention has the advantages of smooth surface, uniform color and no foreign matters, and high peeling strength on the non-aluminized surface of a VMPET film.

The invention discloses a carton lining plastic bag preparation technology which comprises the following steps: a low-density high-pressure polyethylene film is selected, the size of the film is determined as demanded, the film is folio, two squares are cut off at two angles on one side of the line made by folding according to the length of one half of the bottom width of a plastic inner bag, the cut-off film is opened and is erected along the cut-off lines to form a three-dimensional square bag shape, the horizontal sides and central vertical sides at the bottoms of two side faces are sealed, and eyelet work is carried out on long sides and narrow sides of the inner bag as demanded. According to the invention, the sealing sides of the carton lining plastic bag are decreased to four sides, so that the production processes are reduced, the raw material is saved, investment in labor force and the production cost are reduced, and the production efficiency is improved; and in addition, the product is uniform and transparent in color and luster, is free from extraneous odor and foreign matter, and is higher in quality level.
