The invention discloses middle-Jiao and Qi tonifying sulfur-free dried mangoes. The middle-Jiao and Qi tonifying sulfur-free dried mangoes are characterized by being prepared from the following raw materials in parts by weight: 280-300 parts of mangos, 15-25 parts of grapefruits, 8-10 parts of glehnia littoralis, 5-7 parts of pawpaws, 6-8 parts of chickpeas, 6-7 parts of cacao beans, 3-5 parts of rhizoma atractylodis macrocephalae, 4-6 parts of radix bupleuri, 8-10 parts of red date powder, 2-3 parts of corn poppy flower powder and a proper amount of white sugar. According to the invention, fresh mangos are directly processed, are not blanched, are not soaked into sugar for a long time, do not need to adopt sulfur dioxide as a color protecting agent so as to achieve the aims of protecting the color and flavor, and preventing corrosion; the middle-Jiao and Qi tonifying sulfur-free dried mangoes are heavy in fruit flavor, do not have sulfur dioxide residue, are relatively rich in nutrition by adding the raw fruit and vegetable materials, such as grapefruits, and glehnia littoralis, are reasonable in nutritional structure proportioning, and have the efficacies of tonifying middle-Jiao and Qi by being matched with the traditional Chinese medicines, such as rhizoma atractylodis macrocephalae, and radix bupleuri.

The invention discloses a heat-clearing lung-moistening sulfur-free dried mango. The dried mango is characterized by being prepared from the following raw materials by weight: 280 to 300 parts of mango, 15 to 20 parts of peach, 6 to 8 parts of cauliflower, 8 to 16 parts of white radish, 7 to 13 parts of tremella, 6 to 10 parts of water chestnut, 10 to 14 parts of lotus leaf, 7 to 9 parts of Smilax glabra, 8 to 12 parts of lotus root starch, 6 to 8 parts of fritillary bulb powder and a proper amount of white sugar. According to the invention, fresh mango is directly processed; the purposes of color protection, taste preservation and anticorrosion can be achieved without blanching, long-time sugar-soaking and application of sulfur dioxide as a color protection agent; the prepared dried mango has rich fruit aroma and is free of residual sulfur dioxide; fruit and vegetable raw materials like peach, cauliflower and white radish make the dried mango have richer nutrients and a reasonable nutritional structure; and through cooperation between the fruit and vegetable raw materials and traditional Chinese medicines like lotus leaf and Smilax glabra, the prepared dried mango has health care effects like a heat-clearing effect and a lung-moistening effect.

This invention relates to a method for applying braze welding in metal straight tubes including: opening multiple holes with in-flanges along a same line on the side wall of a mainstream tube, plugging shunt tubes into the holes, then filling solders and flux in the gap between them then extending a ring inductorium into the mainstream tube and holding the in-flanges of the holes to let strong enough high frequency current flow through the inductorium to melt the solder then to be turned off and cooled to solder the mainstream and shunt tubes. This invention also discloses a device for the solder method.

The invention discloses an exhaust system of a motor boat engine, which comprises an exhaust pipe, an exhaust flange and a water jacket flange; the exhaust pipe comprises a plurality of exhaust manifolds, an exhaust main, a tail pipe and an exhaust pipe flange, wherein the exhaust manifolds and the exhaust main all adopt double layer structures, and a main pipe water jacket and a manifold water jacket are formed between the inner and outer layer pipe bodies; a water inlet connector is arranged at one end of the outer pipe of the main pipe, and is communicated with the main pipe water jacket, the other end of the water inlet connector is communicated with of the cooling water outlet opening of a generalized oil pan, and the water inlet connector is taken as the main cooling water inlet opening of the exhaust system; the water jacket flange is arranged at the outlet opening of the tail pipe, and a plurality of water outlet holes are arranged on the water jacket flange; the exhaust flange is provided with a cooling water jacket, a plurality of through-holes are arranged in the position where the exhaust pipe flange corresponds to the cooling water jacket; an water inlet hole is arranged in the cooling water jacket, and communicates with the cooling water channel of the engine. The exhaust system has the advantages that the surface temperature of the exhaust pipe of the motor boat engine can be effectively reduced, the thermal protection shield of the exhaust pipe can be eliminated, and at the same time, the cabin temperature and the exhaust gas temperature are reduced, thereby guaranteeing the high reliability of the entire exhaust system.

The invention discloses an anticorrosive paint for a door. The anticorrosive paint is prepared from the following materials in parts by weight: 35-40 parts of barium hydroxide, 20-25 parts of zinc oxide, 15-20 parts of aluminium naphthenate, 7-9 parts of barium chromate, 22-24 parts of ceramic micro-powder, 9-15 parts of silicon carbide, 50-55 parts of novolac epoxy resin, 3-5 parts of aluminium phosphate, 7-10 parts of polyvinyl butyral, 6-9 parts of butadiene resin film former, 4-8 parts of acrylic resin, 2-5 parts of mica, 3-8 parts of inositol hexaphosphate, 12-14 parts of chlorinated paraffin, 8-9 parts of toluenesulfonic acid, 6-8 parts of lithopone, 11-14 parts of biuret, 22-26 parts of polysiloxane, 8-10 parts of boiled wood oil, and 16-21 parts of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate.
