The invention provides an environment-friendly degradable child colored oiled crayon. The colored oiled crayon comprises the following components the content of which is in mass fraction: 0.3-12% of chromogenic reagent, 6-15% of color-developing agent, 35-53% of emulsifying wax, 15-20% of polyethylene glycol, 12-25% of stearic acid, and 2-15% of talcum powder. The child colored oiled crayon disclosed by the invention overcomes the shortcoming that the existing child crayon is difficult to erase, and has the advantages that after writing, color can be removed by wiping with water, and no trace is left. The colored oiled crayon is dust-pollution-free, environment-friendly, non-toxic and innocuous, and can be not only used as a child crayon, but also used to write on a whiteboard for teaching. The production process is simple and mass production of the crayon is easy to realize.

The invention provides a colored pencil lead and a preparation method thereof. The colored pencil lead comprises components in parts by mass as follows: 62-73 parts of sodium thiosulfate, 13-20 parts of a color developing agent, 7-15 parts of CMC (carboxy methylated cellulose) and 0-8 parts of kaolin, wherein the color developing agent consists of sodium carbonate and an acid-base indicator. The preparation method of the colored pencil lead includes steps of weighing the raw materials in proportion, mixing sodium carbonate and the acid-base indicator, adding absolute ethyl alcohol dropwise and mixing to a heavy paste, then pouring molten sodium thiosulfate in and stirring evenly, adding CMC and kaolin, stirring evenly, pouring into a die, drying, and taking out. The provided colored pencil lead can fade both when the lead meets water and when the lead is placed in the air for a long time, is easy to wash when adhering to hands or clothes, is non-residual, non-toxic and harmless, and is suitable for occasions where long-stem storage is not needed, such as temporary marking, calligraphy and painting exercise, and the like.

The invention discloses an information outputting method using coding / decoding, coding static information which needs outputting as a program runs and keeps constant in the running course of the program and making the coding unique; establishing a corresponding relation between code and static information; executing the program and receiving output information; using a code in the output information to inquire the corresponding relation so as to obtain corresponding static information and substituting the corresponding static information for the code in the output information and finally outputting the information.

The invention relates to a solid color writing pen, which consists of an acid-base indicator, an alkaline compound, a humectant, a surfactant, a lubricant, an adhesive, a substrate, ethanol and water.The preparation method comprises the following steps: a mixture is subjected to mixing, heating, dissolving, evenly stirring, film injection and molding to form the solid color writing pen. The solidcolor writing pen can replace chalks and whiteboard pens and is mainly used for teaching board writing, office noting and the like. The color writing pen has the characteristics that the pen has goodstability, smooth writing, does not contaminate cloths and articles, has no pollution of dust and is environment-friendly; the writing can be wiped and fade by a wet cloth instantly; the pen also haslong service life; the ruling length of a 1gram of pen body can reach 446.5 meters; compared with the chalk with the same quality, the writing amount of one color writing pen corresponds to the writing amount of seven common chalks; in addition, the pen also has the characteristics that the pen protects the environment and has bright and clear writing color, and even if under the environment with70 percent relative humidity, the writing can be also remained and does not fade for a long time.

The invention provides a preparation method for black marking glaze for a borosilicate glass insulator. The preparation method comprises the following steps of: adjusting a proper burdening point by taking various chemical pure oxides as basic raw materials, sintering at the high temperature, and water-quenching to obtain basic glass; smashing and grinding, and mixing the smashed basic glass and an organic solvent to obtain the black marking glaze; and finally printing the prepared marking glaze through a silk screen. The preparation method for the black marking glaze for the borosilicate glass insulator has the advantages that: 1, in the preparation method, the marking glaze is prepared by mixing the organic solvent and an inorganic glass material; the marking glaze prepared by the method is encapsulated by an atmosphere furnace at the high temperature and subjected to post chemical polishing, so letters or numbers marked by the marking glaze are hard to fall off and clear, and shortlines and decoloration phenomena are avoided; and the appearance quality of a sealed socket meets the requirements; 2, the marking glaze which is prepared by the method and subjected to the whole test of the sealed socket has no influence on the electric insulation performance; and 3, the marking glaze prepared by the method is directly printed on a glass blank cake, and the glaze is deep black in color, strong in stereoscopic sensation, clear to see words, convenient to operate and simple in process.
