The invention discloses a copper ion test paper, which comprises a substrate (1) and chromogenic test paper (2) fixed on the substrate (1), and is characterized in that the chromogenic test paper (2) is prepared by steeping filter paper in a steeping fluid, taking out the filter paper from the steeping fluid and drying the filter paper, wherein the steeping fluid consists of the following components by weight: 0.07 to 1.4 percent of sodium diethyl dithiocarbamate, 5.7 to 11.4 percent potassium sodium tartrate, 0.036 to 0.71 percent of soluble starch, and 86.49 to 94.194 percent of distilled water. The invention also provides a method for preparing the copper ion test paper. The test paper has the advantages of simple fabrication, low cost, convenient use, no pollution to the environment, and favorability for environmental protection; and besides, the test paper has wide test range, is not required to be operated by a professional, and is particularly applicable to quick field test of copper content.

The invention provides a method for desalting sea sand and a device for desalting the sea sand with the same. The steeping is skillfully combined with sea sand flushing, fresh water is injected into the upper part or the lower part of the steeped sea sand by utilizing the principle of high sand permeability, additional water pressure is artificially applied to the upper part or the lower part of the sea sand body, steep water of which the chloridion content is increased due to steeping is gradually extruded and separated from the sea sand body, and the chloridions on the surface of the sea sand body are repeatedly flushed, thereby achieving the effect of desalting the sea sand, increasing the effect and the efficiency of desalting the sea sand, saving a great amount of fresh water and achieving the effect of getting twice the result with half the effort. The device for desalting the sea sand has the advantages of low early investment and operation cost as well as long service life.

A tea maker comprises a vessel in which is located a conveyor. The conveyor, preferably vertically, transports a carriage. The conveyor and a carriage are surrounded by a tube and are protected from the water in the vessel. An enclosed basket is coupled to the carriage. An external user interface allows a user to select brewing parameters such as the type of beverage brewed, the brewing temperature, and the steeping time. The selection is sent to a processor. The processor then encodes the selection into a control data for the heating assembly or the conveyor.

The invention discloses a method for willow artwork dyeing through a natural indigo pigment. The method comprises the following aspects that (1) indigo extraction is conducted, specifically, a plant raw material is subjected to crushing, fermentation, water soluble extraction and low-temperature drying, and the indigo pigment is prepared; (2) acid-alkali steeping is conducted, specifically, a hydrochlric solution with the concentration being 0.3-0.4% and a sodium hydroxide solution with the concentration being 0.25-0.3% are used to steep a willow artwork correspondingly; (3) cooking for impurity removal is conducted, specifically, impurities in the willow artwork is removed through cooking; (4) steaming for dyeing is conducted, specifically, the indigo pigment with the mass being 11-13% that of distillation boiler water is added, and steam dyeing is conducted; (5) low-temperature drying is conducted, specifically, the dyed willow artwork is dried; (6) infrared color fixing is conducted, specifically, the willow artwork is wrapped through mixed slurry and placed under infrared lamplight with the illumination intensity being 470-520 lux for color fixing; (7) ultraviolet inspection is conducted, specifically, the willow artwork subjected to color fixing is placed under an ultraviolet lamp, and the color fixing condition is inspected; and (8) tung oil layer coating is conducted, specifically, the willow artwork qualified after inspection is coated with tung oil, and after drying, the willow artwork with the natural indigo pigment is prepared.

The invention discloses a method of cultivating rice by layer construction and utilization of straw and soil and solves the problems of crop stalk returning, soil aeration and water-fertilizer coupling. The method includes the steps of 1, performing a bed-furrow project on a rice field for the whole year; 2, performing moisture management before each season of crop harvesting; 3, treating stalks of crops of each season; 4, clearing beds and furrows and spreading soil; 5, planting crops; 6, performing field management; 7, harvesting the crops. The method has the advantages that the soil arable layer structure is changed, and a mud layer, a straw layer and a soil layer are formed from top to bottom; the method is good for deeply placing chemical fertilizers and improving availability of the fertilizers; water content of bed soil is decreased, soil aeration is improved, and availability of natural rainfall is improved; the rice field production process is free of tillage, straw burning and field steeping, ecological benefits are significant, operational energy consumption is reduced, haze is decreased, and irrigation water is decreased.

The invention discloses gelatin and a preparation method thereof. The preparation method comprises steps of steeping fish skin of cold water fish in an alkaline solution; cleaning the fish skin steeped in the alkaline solution and steeping in an acid solution; adjusting the fish skin after the acid treatment step and the alkaline treatment step to be neutral, and extracting in hot water having a temperature of 40-100 DEG C to obtain the first gelatin solution; after the first gelatin solution is filtered, exchanging through a cation exchange resin and then exchanging through an anion exchange resin to obtain the second gelatin solution; and drying the second gelatin solution directly, or concentrating the second gelatin solution and then drying. The preparation method is simple in operation, easy in control, and low in cost. The waste fish skin is fully utilized and the waste is changed into things of value, thus reducing environment pollution. The gelatin is different from warm-water fish gelatin and terrestrial-animal gelatin, and is capable of preventing dehydration synthesis and playing a systematization function, and is suitable for preparing chilled food.
