The environment-friendly faucet structure is simple, convenient and fast to produce and capable of effectively avoiding the problem that heavy metal exceeds the standard, and therefore the domestic drinking water security is guaranteed.

The invention provides a UV (ultraviolet) ink bridging agent and application thereof. The bridging agent comprises resin, a curing agent and a solvent, wherein the resin comprises the following components in percentage by weight: 30-50% of alkyd resin, 10-30% of cellulose nitrate, 20-30% of ester solvent, 0-1.5% of antioxidant, 0-0.8% of tetrafluoroethylene gas-phase wax, 3-8% of diethylene glycol monobutyl ether and 0-1% of leveling agent; the curing agent comprises the following components in percentage by weight: 20-80% of low free TDI (toluene diisocyanate) curing agent raw material and 20-80% of ethyl acetate; and the solvent comprises the following components in percentage by weight: 70-90% of ethyl acetate, 8-20% of ethylene glycol monoethyl ether acetate and 1-10% of diethylene glycol monobutyl ether. The bridging agent provided by the invention is used for the UV ink printing of plates and can effectively enhance the adhesive force of ink on the plates.

The invention provides a method for industrially producing organic selenium-rich original wine with Tibetan cordyceps.The method includes steps of 1), carrying out slant strain cultivation on the Tibetan cordyceps and cultivating seed solution; 2), carrying out submerged fermentation and enlarge cultivation on the seed solution by the aid of water cultivation media, proportionally adding wine into the seed solution and continuing to ferment the seed solution; 3), breaking walls of cells of active mycelia of the Tibetan cordyceps, alternately, soaking and sealing the Tibetan cordyceps by the aid of wine, aging the Tibetan cordyceps and producing aroma; 4), preparing traditional Chinese medicine extract; 5), breaking the walls of mycelia of fermentation liquor of the Tibetan cordyceps, proportionally adding the high-purity traditional Chinese medicine extract and fermentation wine into the fermentation liquor of the Tibetan cordyceps and blending the high-purity traditional Chinese medicine extract, the fermentation wine and the fermentation liquor of the Tibetan cordyceps with one another to obtain the organic selenium-rich original wine.The method has the advantages that the mycelia of the Tibetan cordyceps are subjected to submerged liquid fermentation, baijiu, the sweet wine, the yellow rice wine and the grape wine are respectively added into the Tibetan cordyceps when the sufficient mycelia are obtained, the mycelia of the Tibetan cordyceps continues to be fermented, the walls of the mycelia are broken when active components are sufficient, the mycelia are mixed with the fermentation wine and the extract of radix ophiopogonis, rhizoma polygonati odorati, fructus corni, herba cistanches, herba epimedii, selenium-rich sweet herba gynostemmatis pentaphylli, radix astragali and radix panacis quinquefolii, and accordingly the organic selenium-rich original wine with the Tibetan cordyceps and effects of improving the immunity, resisting kidney gland and thymus gland atrophy, prolonging lives and tendering skins can be produced.

The invention relates to the technical field of agriculture, particularly to cultivating substrate and a preparation method thereof and a ginseng planting method. The cultivating substrate comprises a substrate, a fertilizer and an organic material, wherein the organic material is obtained by anaerobic fermentation, disinfection and drying of waste bacteria sticks, quick lime and microorganisms. The cultivating substrate provided by the invention can be used for effectively preventing soil-borne diseases and effectively preventing soil from being hardened, the air permeability, the water permeability, the water retention and the fertilizer preserving performance are high, and the yield of crops is ensured.

The invention provides a method for printing ultraviolet (UV) ink onto furniture boards. The method comprises the following steps of (1) mixing resin, a curing agent and a solvent according to proportion to obtain a bridging agent; (2) filling the bridging agent into a spraying device to spray and enabling the bridging agent to be sprayed onto cleaned and dried furniture boards; (3) drying the furniture boards with the bridging agent at the normal temperature for more than 30 minutes; and (4) placing the dried furniture boards on a UV ink-jet printer to be subjected to ink spraying. Patterns printed by means of the method have good adhesive force, and the problem that the UV ink patterns on the furniture boards are easy to come off in the prior art. In addition, the UV ink used in the method is water-borne environment-friendly ink, the problem that heavy metal exceeds the standard due to the fact that furniture boards are coated with heavy metal paint is solved, and environment-friendly furniture can be provided for users.
